1.0 INTRODUCTION
Denison Mines (USA) Corp. (DUSA) received a Request for Voluntary Plan and
Schedule to Investigate and Remediate Nitrate Contamination at the White Mesa Mill
(the “Mill”) Site, near Blanding, Utah (the “Request”) (Attachment 1). The Request was
dated September 30, 2008 and was received from the Co-Executive Secretary (the
“Executive Secretary”) of the Utah Water Quality Board, of the Utah Department of
Environmental Quality (UDEQ). In the Request, the Executive Secretary noted that
groundwater nitrate levels have exceeded the State water quality standard of 10
milligrams per liter (mg/L) in certain monitoring wells at the Mill Site. Figure 1 is a
regional map showing the location of the Mill Site.
As a result of the Request, DUSA agreed to submit a plan of action and a schedule for
Executive Secretary approval for completion of a Contamination Investigation Report
(CIR) to determine the physical cause(s), location(s), transfer mechanism(s) and
characteristics of all source(s) of the nitrate contamination in order to form a basis for
and facilitate later submittal of a groundwater Corrective Action Plan (CAP) that meets
the requirements of Utah Administrative Code (UAC) R317-6-6.15D, or to demonstrate
conclusively that DUSA did not cause or contribute to the nitrate contamination in any
manner and that, as a result, such a CAP is not necessary. DUSA retained INTERA,
Incorporated (INTERA) to develop a plan and schedule for completing this CIR and, if
necessary, a CAP. A Plan and Schedule for Nitrate Contamination Investigation Report
and Groundwater Corrective Action Plan (The Plan) (INTERA, 2008) was submitted to
the Executive Secretary on November 19, 2008. A Stipulated Consent Agreement
(Agreement) between DUSA and the Utah Water Quality Board (Board) was entered
into in January, 2009. Subsequently, in a letter dated December 1, 2009, UDEQ noting
that elevated chloride concentrations exist, apparently coincident with elevated nitrate
concentrations, recommended that DUSA also address and explain the elevated
chloride concentrations in this Report. Therefore, this Report will serve as a CIR for both
nitrate and chloride at the Mill Site.
The purpose of this Report is to characterize nitrate and chloride contamination in
groundwater at the Mill Site. The contamination investigation activities follow The Plan,
as amended by the Agreement and the requirements found in UAC R317-6-6.15(D). As
will be discussed in detail in Sections 2 and 3, the following conclusions are reached in
this CIR:
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 2
1. The nitrate and chloride are extensive and appear to originally come from the
same source.
2. That source is upgradient of the Mill property more than 1.2 miles from the Mill
facilities, is not the result of Mill activities and was not caused or contributed to in
any manner by Mill activities.
As a result, DUSA has concluded that it should not be required to prepare a CAP for
nitrate/chloride contamination that is from an off-site source.
1.1 Documents Incorporated by Reference
The Mill has been the subject of numerous studies. According to UAC R317-6-6.15 (C),

Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 4
2.0 CONTAMINATION INVESTIGATION ACTIVITIES
All potential contributing surficial sources that could generate nitrate and chloride in the
perched aquifer that have been identified to date, have been described in Sections 2, 3,
4 and 5 of the Source Review Report for Nitrate and Chloride in Groundwater at the
White Mesa Mill dated December 30, 2009, prepared by Ms. Jo Ann Tischler (the
Source Report), a copy of which is appended to this CIR as Attachment 2.
Contamination investigation activities included the above referenced analysis of
possible sources at the Facility, installation of new perched groundwater wells, sampling
of groundwater in the new wells, and analyses of groundwater in all wells and wildlife
ponds.
Installation of 19 new monitoring wells (Figure 2) has allowed the nitrate and chloride
plumes to be fully bounded at the Site (Figures 3 and 4). On Figure 3, nitrate iso-
contours start at 5 mg/L because that value appears to separate the plume from
background. However, as evident from Figure 3, the 10 mg/L contour that defines the
groundwater compliance limit for nitrate at a number of wells at the Site as specified in
the Groundwater Discharge Permit No. UGW370004 (GWDP) is completely closed and
defined at the Site. Per discussions with UDEQ, the nitrate plume is considered to have
been bounded when the concentrations of nitrate in monitoring wells upgradient,
downgradient, and in both crossgradient directions are less than 10 mg/L. There is no
groundwater standard for chloride but the iso-contours start at 100 mg/L because that
value appears to separate the plume from background.
A feature of the plume maps is that the nitrate (Figure 3) and chloride plumes (Figure 4)
are co-located geographically. Almost all locations that have elevated nitrate
concentrations also have elevated chloride concentrations, implying that the nitrate and
chloride impacts to groundwater had the same source. However, the nitrate plume
shows a lobe extending to the southeast coincident with the chloroform plume (Figure 5)
but the chloride plume does not. This indicates that elevated nitrate was present in the
chloroform plume but chloride was not. The chloride plume demonstrates that there are
two distinct plumes; a nitrate-chloride plume and the chloroform plume with distinctly
different sources.
2.1 Possible Sources of the Pollution at the Facility
As discussed in detail in Section 3, based on new well installation and recent
groundwater sampling, the source of nitrate and chloride contamination is off the DUSA
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 5
property to the northeast (see Figures 6 and 7). However, the Source Report, which is
appended to this Report (Attachment 2), identified the following possible sources of
nitrate and/or chloride in groundwater at the Site:
 The septic leach fields at the site;
 The municipal sewage plant discharge water used historically as Mill water
makeup;
 Livestock activities at the wildlife ponds;
 Livestock activities at the Historic Pond;
 Agricultural activities;
 The former Fly Ash Pond;
 Potential historic spills of ammonia-bearing and/or chloride-bearing process
chemicals;
 Potential breach in the Mill circuit floor drains or tailings transfer lines; and
 A potential leak in the Mill’s tailings cells.
As will be discussed in more detail below, the municipal sewage plant discharge water
used historically as Mill water makeup is the best candidate for the source of both
elevated nitrate and elevated chloride in groundwater. However the following sections
will review potential sources and compare their potential for contributing nitrate and
chloride to groundwater based on data collected during this study.
2.1.1 Potential Tailings Cell Source
Elevated nitrate and chloride concentrations at TWN-3 are clearly a part of the plume.
This monitoring well is more than 1,000 feet upgradient of the tailings cells. It is unlikely
that tailings solutions could travel this distance horizontally in the vadose zone. Further
the plume at TWN-3 is clearly spatially and chemically related to the plume at TWN-19
which is more than 7,200 feet upgradient of any tailings cell.
Other suggested possibilities include a groundwater mound from the tailings cells that
might cause elevated nitrate and chloride concentrations upgradient. A quick calculation
for nitrate to evaluate this possibility (a calculation for chloride would be similar)
suggests that on the order of eleven percent tailings solution (assuming the highest
recently observed nitrate concentration in the tailings of 290 mg/L) would have to mix
with unimpacted groundwater (assuming 1 mg/L) in order to account for the observed
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 6
mass of nitrate in groundwater, assuming an average nitrate concentration in the plume
above the 20 mg/L isopleth of 30 mg/L.
The size of the nitrate plume above 20 mg/L is approximately 40 acres, or 1,800,000
square feet in map area (Figure 3). Assuming 45 feet of saturation (Chloroform
Investigation Report) and a porosity of 0.2, there are 16,200,000 cubic feet or
121,176,000 gallons of groundwater in that area. Eleven percent of that is 13,329,360
gallons (approximately 41 acre feet) which is a conservative estimate of the volume of
tailings solution that would have to be mixed with groundwater to account for the mass
of nitrate in the portion of the plume above 20 mg/L nitrate.
That amount of seepage from the tailings cells would certainly generate a groundwater
mound. Such a mound would have to be on the order of 5 feet on average over the
entire 40 acres, but would likely be much higher than that at the centroid of the plume
and would taper off toward the edges of the plume. However, no such mounding exists
under the tailings cells. While groundwater mounding can be observed towards the
eastern portion of the site, away from the tailings cells, it is clearly related to the wildlife
ponds and not the tailings cells (See Figure 8). As a final point, if the concentration of
nitrate in tailings documented in the Statement of Basis (24 mg/L) were used in the
calculation, no amount of tailings solution would bring the plume concentration to 30
mg/L.
Based on the results of the nitrate investigation, the discussion above, and recent
studies by the University of Utah (Solomon and Hurst, 2008) indicating that the Mill’s
tailings cells have not leaked, the tailings cells have been removed from the list of
potential sources of nitrate and chloride at the Site.
2.1.2 Potential Mill Circuit Source
The Mill circuit is located downgradient of elevated nitrate and chloride concentrations
at TWN-3, and the same argument advanced for the tailings cells applies. The plume at
TWN-3 is clearly spatially and chemically related to the plume at TWN-19 which is more
than 6,900 feet upgradient of TWN-3. Additionally, there is no known history of leaks or
spills of the magnitude required to supply the mass of nitrate currently observed in
groundwater. Further, as noted in the Source Report, spills of these materials are too
finite a phenomenon to account for an ongoing plume on their own. Therefore, a Mill
circuit source has been removed from the list of potential sources of nitrate and chloride
at the Site. Similar arguments rule out a Mill laboratory source from the list of potential
sources of nitrate and chloride at the site.
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 7
2.1.3 Potential Fly Ash Pond Source
As with the potential tailings cell and Mill circuit the former Fly Ash Pond is also
considerably downgradient of demonstrated elevated levels of nitrate and chloride in
groundwater in samples from TWN-3 and TWN-19. The contents of the Fly Ash Pond
were removed and the pond was covered and closed in 1989. The Fly Ash Pond was
called a pond because it was located at a low point that collected storm run-off water.
However, standing water in the pond was pumped regularly to the tailings cells thereby
reducing the pond’s ability to drive any recharge to groundwater. Further, a component
of fly ash is lime (CaO). This chemical reacts with water (H2O) to form calcium
hydroxide [Ca(OH)2]. This property of fly ash leads to the formation of a kind of natural
cement that would tend to form a barrier to infiltration (Scott and Thomas, 2007),
favoring evaporation of pond solutions rather than groundwater recharge. Therefore, a
Fly Ash Pond source, while possible, is less likely than potential sources upgradient of
TW4-25. This potential source has been removed from the list of potential sources of
nitrate and chloride at the Site.
2.1.4 Potential Septic System Sources
As above, this potential source cannot explain the nitrate and chloride plume far to the
north of the Mill Site. However, a number of septic leach fields exist at the Mill Site, and
septic systems have caused regional nitrate contamination in many areas (McQuillan,
2004). Figure 7 shows five separate leach fields at the Mill Site along with associated
piping. Two of the Site leach fields, the Former Office Leach Field and the Scale House
Leach Field, apparently gave rise to the chloroform plume that is currently under
remediation. It is worth noting that the nitrate and chloride plume is chemically distinct
from the chloroform plume in that the chloroform plume has distinctly lower levels of
chloride. Therefore, this potential source has been removed from the list of potential
sources of nitrate and chloride at the Site. Any nitrate in the chloroform plume that has
resulted from these leach fields will be remediated under the chloroform investigation.
2.1.5 Potential Frog Pond Water Sources
Until the early 1990s, process water for the Mill was limited to the deep water supply
wells on Site, and the Mill sought additional sources of process water. Recapture
Reservoir was not constructed until 1988-1989, and the pipeline from Recapture
Reservoir to the Mill was not completed until around 1991-1992. From the mid 1980s
until the Recapture Reservoir water was first piped to the Mill in 1991-1992, the Frog
Pond served as an additional water source for Mill operations.
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 8
This source is considered to be the most likely explanation for the distribution of the
nitrate and chloride plume. The waste water treatment facility described in the Source
Report is located several miles upgradient of the Mill Site (Figure 6) but discussions with
Mill staff indicate that effluent from that facility was allowed to flow to a pond (Frog
Pond) near the Mill boundary where it was subsequently piped to the northern-most
Wildlife Pond at the Site and to another holding pond on Site for Mill makeup water
(Lawzy Lake, see Figures 6 and 7). The Mill staff reports that this water had a bad odor
and may have had a high sludge content. Nitrate and chloride are commonly associated
with wastewater treatment effluent (McQuillan, 2004).
At the Frog Pond an electric pump carried the water for use at the Mill via underground
pipe to ponds at the rate of about 200 gallons per minute (gpm). Just north of the Mill’s
restricted area, the water could be diverted to either the northern most wildlife pond or
to a secondary pond, referred to as “Lawzy Lake”. At the wildlife pond a diesel pump
was activated when water was needed in the Mill. Water was then pumped from the
northern wildlife pond to the Mill’s pre-leach tanks, which acted as water storage for the
Mill. The water in Lawzy Lake was gravity fed to a sump (the “Lawzy Sump”) within the
restricted area. Once the water reached the sump, it was pumped to the pre-leach tanks
for water storage (Figure 7). Neither the wildlife pond nor Lawzy Lake is lined.
This potential source term was a high priority during this contamination investigation for
several reasons. The period of Mill use of water from the waste water treatment plant
was from the mid 1980s to about 1991 or 1992 when it was replaced with water from
Recapture Reservoir. As documented in the Background Report (INTERA, 2007),
groundwater levels at the Site have been influenced by the Wildlife Ponds so we know
that the head in those ponds has been sufficient to drive infiltration to the water table.
The “slug” like character of the nitrate and chloride plume is consistent with a source
that has been removed. The distances from the northern-most Wildlife Pond and Lawzy
Lake to the centroid of the nitrate plume are approximately 2,300 feet and 2,100 feet,
respectively. Assuming 26 years since nitrate/chloride laden water entered the system,
groundwater would have had to travel at an average velocity of 88 feet per year (ft/yr)
from the northern-most Wildlife Pond and 81 ft/yr from Lawzy Lake to account for the
current distribution of nitrate concentrations. The velocity of 88 ft/yr from the northern-
most Wildlife Pond is a relatively high velocity compared to other values that have been
calculated for the Site, but possible given the high gradient in this limited portion of the
Site due to mounding at the wildlife ponds. Further, the eastern portion of the Site is
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 9
known to have higher permeability than the western portion (see the Preliminary
Contamination Investigation Report [HGC, 2007]). The Lawzy Sump is even closer to
the plume. The Frog Pond was constructed prior to Mill operations, by creation of a dike
to capture surface water, by local ranchers in order to capture available surface waters.
The Mill was not involved in any way in the construction of the Frog Pond.
For the above reasons Lawzy Lake, the Lawzy Sump, and the northern-most Wildlife
Pond are likely infiltration points for Frog Pond water. These potential infiltration points
have been addressed by installation of two monitoring wells. One (TWN-3) was installed
half way along a line between the north end of the Mill building and Lawzy Lake.
Analytical results of samples of groundwater from well TWN-3 (29 mg/L nitrate and 106
mg/L chloride) indicate that this well may be near a potential source. The other
monitoring well (TWN-4) was installed on a line approximately half way between the
north end of the Mill building and the northern-most Wildlife Pond. Groundwater
samples from TWN-4 contained 0.4 mg/L nitrate and 11 mg/L chloride.
Another possible explanation for the distribution of nitrate and chloride using the Frog
Pond water source is that the pipeline from the Frog Pond to the northern wildlife pond
and Lawzy Lake may have leaked. However, it seems likely that leaks would have been
noticed, particularly leaks of enough volume to travel to groundwater and add the
observed mass of nitrate and chloride.
2.1.6 Livestock Activity at Wildlife Ponds and Historic Pond
The northern-most Wildlife Pond was a stock watering pond for years prior to
construction of the Mill. The Historic Pond, which no longer exists, but was located
where the Mill’s sulfuric acid tank is currently located, (Figure 7) pre-existed
construction of the Mill by several decades, tracing back possibly to the 1920s.
Livestock can generate nitrate in and around stock watering ponds and salt licks for
livestock can generate chloride, and the water head in the ponds could potentially drive
those nitrates into the groundwater. However these mechanisms alone would be
unlikely to generate enough mass to account for the current mass of nitrate and chloride
observed in groundwater.
2.1.7 Agricultural Sources
The Mill is located south of Blanding, Utah in a rural agricultural region of the state.
Land uses proximal to the Mill include farming, ranching, cattle grazing and feed and

grain silos. Those activities could generate both nitrate and chloride to groundwater.
While it is possible that agricultural practices on neighboring properties that occurred at
some time in the past (but which no longer occur) could have contributed a slug of both
nitrate and chloride contamination to groundwater, this is difficult to quantify and
appears much less likely than the Frog Pond source discussed above.
2.2 New Wells
TWN-1 through TWN-19, were drilled, completed, and developed in the same manner
as the chloroform investigation wells as specified under UAC R 317-6-6.3 (I) (6) and the
Mill’s State of Utah Division of Water Quality GWDP. The locations of the new wells are
shown in Figure 2.
2.3 Groundwater Sampling
Groundwater in all groundwater wells on Site, including groundwater in the 19 new TWN
wells was collected and analyzed for nitrate and chloride as part of the contamination
investigation. The rationale behind the groundwater sampling plan is described below.
2.3.1 Sampling Design
New sampling locations have been determined based on concentrations of nitrate and
chloride from previous analytical results, including quarterly groundwater and chloroform
reports and an analysis of potential sources (see Section 2.1 above). Groundwater
samples were collected according to Section 6 “Ground Water Sampling and
Measurement of Field Parameters” of the White Mesa Uranium Mill Groundwater
Monitoring Quality Assurance Plan (the QAP) (DUSA, 2009, Attachment 3). Sample
locations, parameters, and rationale are listed in Table 1 of this Report.
Table 1 of the QAP presents the analytical method, reporting limit, maximum holding
time, and sample preservation requirements (including temperature) for nitrate and
chloride samples.
2.3.2 Sampling Quality Assurance/Quality Control
Sample collection, handling, identification, and shipping were performed according to
the QAP. See the Initial Nitrate Monitoring Report included as Attachment 4, for a
QA/QC analysis and for identification of any deviations from the requirements of the
QAP.

2.3.3 Laboratory QA/QC and Reporting
To ensure quality of laboratory analysis, the Mill’s contract analytical laboratory (Energy
Laboratories, Inc.) was required to analyze quality assurance/quality control (QA/QC)
samples as specified by the analytical method. This QA/QC was performed in the same
manner as the quarterly groundwater and chloroform analysis, and according to the
QAP. See the Initial Nitrate Monitoring Report included as Attachment 4.
Laboratory analytical reports were submitted to DUSA and INTERA in the form of an
Electronic Data Deliverable, which was verified by INTERA.

3.0 CHARACTERIZATION OF POLLUTION
The following sections describe the characterization of pollution as required by R317-6-
6.15 D 1.
3.1 Characteristics of Contaminants in Groundwater and Contributing Surficial
Contaminants
The contaminants of concern have been identified as nitrate and chloride in the perched
aquifer at the Mill Site. Characteristics of nitrate and chloride in groundwater are
described in the following sections.
3.1.1 Amount, Form, Concentration, and Toxicity of Contaminants
Based on Figure 3 and Figure 4, elevated concentrations of nitrate and chloride appear
to be co-located across the Site, suggesting derivation from the same source.
3.1.1.1 Nitrate
Groundwater from Site monitoring wells has been sampled and nitrate has been
measured as nitrate+nitrite and reported as nitrogen. Nitrate (NO3-) and nitrite (NO2-)
are naturally occurring inorganic ions that are part of the nitrogen cycle. Because nitrite
is easily oxidized to nitrate, nitrate is the compound predominantly found in
groundwater. Nitrates themselves are relatively nontoxic. However, when swallowed,
they are converted to nitrites that can react with hemoglobin in the blood, oxidizing its
divalent iron to the trivalent form and creating methemoglobin. This methemoglobin
cannot bind oxygen, which decreases the capacity of the blood to transport oxygen, so
less oxygen is transported from the lungs to the body tissues, thus causing a condition
known as methemoglobinemia (Argonne National Laboratory, 2005).
The U.S. Environmental Protection Agency (EPA) has developed toxicity values to
estimate the risk of non-cancer health effects from ingesting nitrates and nitrites. The
toxicity value used to estimate a non-cancer effect following ingestion is called a
reference dose (RfD). An RfD is an estimate of the highest dose that can be taken in
every day without causing an adverse effect. The RfD for nitrate was developed
considering the concentration at which methemoglobinemia was indicated at levels
above 10% for 0- to 3-month-old infants. This was based on a daily intake of formula
made with water containing 10 mg/L of nitrate as nitrogen. This reflects the amount of
nitrogen within a nitrate molecule, where 1 mg nitrate as nitrogen = 4.4 mg nitrate as
measured in the water.
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 13
Most cases of infant methemoglobinemia are associated with exposure to formula
prepared with drinking water at nitrate-nitrogen levels at least two times higher, or
exceeding 20 mg/L nitrate-nitrogen. For nitrite, the RfD is based on a 10-kilogram (22-
pound) child drinking 1 liter, or about 1 quart, of water every day. The RfD represents a
“safe daily dose” and so is compared to the amount an individual is estimated to take in
every day, as a ratio (Argonne National Laboratory, 2005). Thus the EPA Standard for
nitrate in groundwater is 10 mg/L as nitrogen.
With respect to the amount and concentration of nitrate in the plume, the highest nitrate
level that has been detected at the Site is 45.3 mg/L in monitor well TW4-24 in a sample
collected on June 25, 2008. Nitrate levels in that well have declined and the most
recently measured value in a sample of groundwater, taken on September 15, 2009, is
30.7 mg/L. Typical concentrations in the area of the nitrate plume range from 5 mg/L to
25 mg/L. The areal extent of the plume is depicted on Figure 3. The vertical extent is
the perched groundwater zone within the area of the plume.
3.1.1.2 Chloride
Chloride is considered to be a major element that occurs in almost all groundwater
(Hem, 1992) and occurs as a chloride ion (Cl-). There is no human health standard for
chloride in groundwater. The EPA Standard for chloride in drinking water (250 mg/L) is
an aesthetic standard related to the salty taste of water with chloride concentrations in
excess of that amount. The recommended EPA criterion for the propagation of wildlife is
1,500 mg/L.
With respect to the amount and concentration of chloride in the plume, the highest
chloride level that has been detected at the Site is 1,180 mg/L, again in monitor well
TW4-24 in a sample collected on September 10, 2008. Chloride levels in that well have
declined and the most recently measured value in a sample of groundwater, taken on
September 15, 2009, is 618 mg/L. Typical concentrations in the area of the nitrate
plume range from 100 mg/L to 300 mg/L. The areal extent of the plume is depicted on
Figure 4. The vertical extent is the perched groundwater zone within the area of the
plume.
3.1.2 Environmental Fate and Transport
Nitrate and chloride behave in a similar way in many groundwater systems. With some
exceptions described below, both are non-reactive and conservative constituents whose
concentrations are diminished in groundwater only by diffusion and dispersion with
travel distance.
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 14
3.1.2.1 Nitrate
Since it is very soluble and does not bind to soils, nitrate has a high potential to migrate
to ground water. Because it does not evaporate, nitrate/nitrite is likely to remain in water
until consumed by plants or other organisms (http://www.epa.gov/safewater/
contaminants/dw_contamfs/nitrates.htm). The retardation factor (R) is one of the
coefficients that describe the migration abilities of particular components in
groundwater. It shows how many times the migration of the substance subjected to
adsorption is slower than the actual speed of water flow in pores. The average intensity
of nitrate adsorption is described as low, and the retardation factor ranges between 1
and 2 (Deutch, 1997). However, if nitrate is discharged into anoxic ground water, or if
oxic ground water containing nitrate either migrates into anoxic conditions or is made
anoxic by anthropogenic discharges, de-nitrification can occur, converting nitrate to
nitrogen gas (N2) (McQuillan, 2004).
3.1.2.2 Chloride
Chloride ions do not significantly enter into oxidation or reduction reactions and they
form no important solute complexes with other ions unless the chloride concentration is
extremely high. Chloride ions do not form salts of low solubility, are not significantly
adsorbed on mineral surfaces, and play few vital biochemical roles. Thus, the
attenuation of chloride ions in the hydrologic cycle is largely through the physical
processes of hydrodynamic dispersion and diffusion (Hem, 1992).
3.2 The Areal and Vertical Extent of the Contaminant Concentration, Distribution
and Chemical Make-Up
Groundwater at the Mill has been monitored for the past 30 years; therefore, certain
characteristics of nitrate and chloride contamination have already been determined.
Prior to the contamination investigation activities, the nitrate and chloride plumes were
well constrained in the downgradient direction. They had clear boundaries to the west
and to the south.
On the east side, apparently nitrate partially comingles with nitrate associated with the
chloroform plume. Groundwater extraction for remediation of chloroform may have
caused additional comingling in this area obscuring any relationship that may have
existed between the two plumes. New wells have defined an elongated plume extending
over a mile to the northeast from the northern-most wildlife pond to DUSA’s property
boundary (Figures 3 and 4). Sampling has confirmed the association of nitrate with
chloride in this plume. The plume exists in two distinct parts divided by a zone of low
concentrations in the vicinity of the northern-most wildlife pond.
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 15
3.2.1 New Wells
The new monitoring wells were installed according to UAC R317-6-6.3(I)(6). Initially,
DUSA installed four new monitoring wells (TWN-1 through TWN-4) in late January,
2009 as described in the Plan (INTERA, 2008). Sampling of those wells revealed that
elevated nitrate and chloride concentrations exist north of the Mill Site proper and north
of the ore pads (in TWN-3). Based on this information, an additional six monitoring wells
were installed in July 2009 (TWN-5 through TWN-10). Sampling of those wells revealed
that elevated nitrate and chloride concentrations exist still further north at TWN-9.
Therefore, an additional nine monitoring wells were installed (TWN-11 through TWN-19)
in late September and early October, 2009 to further bound the plume.
Figures 3 and 4 present nitrate and chloride data, respectively, from November 2009
and contoured by the krieging routine in SURFER 8. On Figure 3, nitrate iso-contours
start at 5 mg/L because that value appears to separate the plume from background.
However, as evident from Figure 3, the 10 mg/L contour that defines the groundwater
compliance limit for nitrate at a number of wells at the Site as specified in the GWDP is
completely closed and defined at the Site. Above the 10 mg/L contour, nitrate contours
increase in 10 mg/L increments. There is no groundwater standard for chloride but the
iso-contours start at 100 mg/L because that value appears to separate the plume from
background and thereafter chloride contours increase in 100 mg/L increments.
These figures demonstrate that a plume exists in groundwater that is clearly unrelated
to the tailings cells and other Mill facilities and is apparently moving southwest with
groundwater flow from a source northeast of the Mill Site. This plume is distinctive in its
association of nitrate with chloride and, as described in Section 2, can be distinguished
from the chloroform plume based on its distinctive chemistry. The most upgradient
location within the nitrate-chloride plume is the new monitoring well TWN-19,
approximately 1.4 miles upgradient of the tailings cells and at the north east boundary of
the Mill property, where nitrate concentrations are 7.4 mg/L and chloride concentrations
are 125 mg/L. Currently, the centroid of the plume is downgradient of the Mill office
building, at TW4-24 where current nitrate concentrations in groundwater are near 30
mg/L and chloride concentrations are near 600 mg/L.
The current plume configuration appears to approximate “plug-flow” behavior, where a
“slug” of contamination moves as a mass with groundwater. If so, the distribution of
nitrate and chloride concentrations suggest a point source of nitrate contamination
Nitrate Contamination Investigation Report
White Mesa Mill Site

upgradient of the Mill property that contributed to groundwater for a finite period of time
and has subsequently been removed.
3.2.2 Hydrogeological Report of New Wells
Hydraulic testing of new monitoring wells TWN-1 through TWN-19 was conducted to
estimate perched zone hydraulic properties in the vicinity of each new well. The
complete Perched Nitrate Monitoring Well Hydraulic Tests report (HGC, 2009) is
included in this Report as Attachment 5.
Slug test data were collected and analyzed using AqtesolvTM software. Estimates of
hydraulic conductivity range from 3.6 x 10 -7 centimeters per second (cm/s) at TWN-7
to 0.0142 cm/s at TWN-16. Except for the hydraulic conductivity estimate at TWN-16,
values are within the range previously reported for the Site. Pore zone velocities along
hypothetical pathways through elevated nitrate areas have been calculated as
approximately 0.55 ft/yr to 7 ft/yr in the northeast area plume. Pore velocity for the Mill
area plume is 23 ft/yr.
These values are lower than might be expected. However, coupling the fact that the
highest conductivity ever measured at the Site is located in this area and the relatively
small number of measurement locations (19 over an approximately one square mile
area) it is unlikely that these are accurate estimates of actual pore velocities. Note that
wells installed at a higher density in a smaller area for the chloroform investigation
(Hydro Geo Chem, 2007) confirmed higher hydraulic conductivities in that area.
Another line of evidence that hydraulic conductivities in the area of the nitrate and
chloride plume might be higher than the sample would indicate lies in the shape of the
water table surface (Figure 8). Note that southwest of the Mill Facility itself, groundwater
flow directions change to more westerly and the gradient steepens. This is a classic
example of flow crossing a boundary from a zone of higher permeability to a zone of
lower permeability.
The gradient steepens to accommodate the lower permeability and flow is refracted into
a new direction. This is known as the tangent refraction law. Analytically, a refraction of
flow lines occur such that the permeability ratio of the two zones equals the ratios of the
tangents of the angles the flow lines make with the normal to the boundary (Domenico
and Schwartz, 1990). The nitrate and chloride plume occurs in the area of high
conductivity where the water table is behaving in a similar way to the area of known
higher conductivities associated with the chloroform plume (Figure 5).

3.2.3 Groundwater Analysis of New Wells
The Sampling Plan submitted to the Executive Secretary as part of The Plan (INTERA,
2008) sets out a plan to define the north and northeast boundary of the nitrate plume.
The following activities have been completed according to the Plan and the following
deliverables have been prepared and will be submitted to the Executive Secretary along
side this Report:
 Drilled, installed, and completed 19 new monitoring wells (TWN-1 through TWN-
19);
 A recovery test and aquifer testing to determine hydraulic conductivity was
performed on each of the new monitoring wells;
 The 19 new monitoring wells were developed and sampled for nitrate and
chloride;
 A hydrogeological report (“Site Hydrogeology and Estimation of Groundwater
Pore Velocities in the Perched Zone, White Mesa Uranium Mill Site Near
Blanding, Utah” [HGC, 2009]) including the results from the recovery tests and
aquifer testing on the new monitoring wells was prepared (Attachment 5); and
 A QA/QC analysis was performed on all nitrate and chloride sample results for
the 19 new wells, as contained in the Initial Nitrate Report (Attachment 4).
The results of groundwater sampling for nitrate and chloride are presented in Table 2.
3.3 Contaminant Migration
As stated above, calculated pore zone velocities along hypothetical pathways are
approximately 0.55 ft/yr to 7 ft/yr in the northeast area plume. Calculated pore velocity
for the Mill area plume is 23 ft/yr. These travel times are not long enough to have
transported nitrate and chloride from the upgradient to the downgradient portions of the
two areas within a reasonable time frame. Assuming the 23 ft/year pore velocity and a
source just upgradient of the DUSA property boundary in the vicinity of TWN-19, it
would take over 300 years for nitrate and chloride to arrive at monitor well TW4-24. Yet
the plume at TW4-24 is clearly spatially and chemically related to the plume at TW4-19.
Spatially, it can be traced on a trajectory from TWN-19 to MW-19 where it is separated
from the Mill area plume by only a few hundred feet. Chemically, the areas of elevated
nitrate correspond to the areas of elevated chloride suggesting a common source for
the two constituents and both plume areas.
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 18
Possible explanations for the above observations include: 1) actual pore velocities are
higher than calculated pore velocities, 2) each nitrate area has resulted from multiple
localized sources that have the same water type, or 3) some combination of the above.
The following discussions will examine each of these possibilities in detail.
3.3.1 Velocities
Pore velocities are calculated by multiplying the measured hydraulic conductivity times
the hydraulic gradient and dividing the result by the effective porosity of the aquifer
matrix. The measured hydraulic conductivities are the average of conductivities in the
various sedimentary facies over the entire saturated thickness at the well where testing
is done. This means that if sandstone and claystone are both within the saturated
thickness at a well, the resulting measured hydraulic conductivity is an average of the
conductivity of both aquifer matrix types. However, the bulk of groundwater flow will be
in the sandstone that could result in an underestimate of hydraulic conductivity.
Fluvial environments such as those represented by the Burro Canyon Formation
comprise lens-like interfingering of the following deposit types (sedimentary facies):
 Channel floor deposits comprising coarse sand or gravel;
 Point bar deposits of fine-grained sand; and
 Flood plain deposits comprising silt and mud.
As sediment deposition occurs over time, these deposit types are distributed back and
forth across the larger stream channel, producing the characteristic discontinuous
lens-like nature of a fluvial geologic unit. In general, groundwater moves relatively
quickly through the coarse channel sand and gravel but much more slowly through silt
and clay flood plain deposits. Hydraulic heads can be maintained within the unit but the
bulk of groundwater flow will be restricted to the gravel and sand facies.
In general, measured hydraulic conductivities are higher to the north and east of the Mill
tailings impoundments and lower to the south and west. The plume is in the north and
east where some of the highest conductivities have been measured, so it may be
appropriate to assume an increased hydraulic conductivity and a corresponding
increased pore velocity. However, given the distance of 1.4 miles from TWN-19 to TW4-
24, it would take 60 years for contamination to make the trip assuming a pore velocity of
120 ft/yr. This value is almost five times higher than any calculated and not consistent
with Site observations, for example at MW-30 downgradient of the highest plume
Nitrate Contamination Investigation Report
White Mesa Mill Site

concentrations where chloride concentrations of 128 mg/L in 2005 have declined to 113
mg/L in February 2009.
3.3.2 Multiple Sources
Nitrate and chloride in monitor well TWN-19 clearly have their source off of DUSA’s
property to the north indicating that the ultimate source of contamination lies off of the
DUSA property. Potential sources to the north include extensive agricultural irrigation
just to the north of the property boundary that is plainly visible on aerial photographs
(Figure 6) and the Frog Pond to the northeast.
Nitrate contamination from the use of fertilizers during agricultural irrigation is well
documented (Hem, 1992; McQuillan, 2005) and Hem cites an example in Arizona where
83 mg/L nitrate in groundwater was accompanied by 205 mg/L chloride, which is in the
general range observed in the plume at White Mesa. Furthermore, water table contours
(Figure 8) show what may be the toe of a groundwater mound located directly north of
TWN-12 where mounding from irrigation might be expected. However, nitrate and
chloride contamination appears to be coming from the east of TWN-12, suggesting the
Frog Pond as a potential source.
The presence of associated nitrate and chloride in septic and wastewater treatment
systems is well documented (McQuillan, 2005). Currently, the Frog Pond does not
contain elevated levels of nitrate and chloride. However, anecdotal evidence suggests
that water in the pond has exhibited a septic/sewage odor in the past (which could have
been mistaken for a marshy smell). Furthermore, there is a wastewater treatment facility
located 1.2 miles north of the Frog pond. Effluent from the water treatment plant
overflows into an arroyo that leads to Corral Canyon, just east of the Mill Site. This
overflow was dammed by local ranchers prior to construction of the Mill to form the Frog
Pond. DUSA has no information on current or past operating practices at the treatment
facility.
If either agricultural irrigation or the Frog Pond is the ultimate source of the nitrate and
chloride plume, the dilemma of the long travel times required to move the plume to its
current location remains to be explained.
3.3.3 Combination of Faster Travel Times and an Off-Site Source
A plausible explanation that would account for the observed spatial and chemical
relationships that characterize the plume relies on water from the Frog Pond transported
to secondary storage at the Mill Site. Until the early 1990s, process water for the Mill
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 20
was limited to the deep water supply wells on Site, and the Mill sought additional
sources of process water. Recapture Reservoir was not constructed until 1988-1989,
and the pipeline from Recapture Reservoir to the Mill was not completed until around
1991-1992. From the mid 1980s until the Recapture Reservoir water was first piped to
the Mill in 1991-1992, the Frog Pond served as an additional water source for Mill
operations.
The timing of these events suggests the following scenario: The unlined Frog Pond
contained nitrate and chloride, which entered the groundwater and began migrating to
the southwest. Meanwhile, DUSA pumped nitrate and chloride laden Frog Pond water
to the northern-most wildlife pond and Lawzy Lake during the period from the early
1980’s to the early 1990’s where it began to seep into groundwater aided by the artificial
head maintained on those ponds. The artificial head created a groundwater mound
(notably still present under the wildlife ponds) and began driving elevated
concentrations of nitrate and chloride west from the wildlife pond and south from Lawzy
Lake, but also northeast toward TWN-9 due to circular gradients away from the mound.
This nitrate and chloride laden water could also have reached the perched zone from
the Lawzy Sump.
When Recapture Reservoir water replaced the Frog Pond in the early 1990’s, Lawzy
Lake was abandoned and the wildlife ponds were refilled with clean Recapture
Reservoir water. The groundwater mound beneath Lawzy Lake dissipated and
contamination from that infiltration point continued to migrate south, meanwhile the
clean groundwater mound beneath the wildlife ponds continued to push already
contaminated groundwater to the north where it impinged upon and joined with the
plume traveling southwest from the Frog Pond. The wildlife pond’s groundwater mound
is also still pushing contamination to the west and the slug that is now centered on
TW4-24 is moving southwest away from the stagnant zone in groundwater that results
from the mound upgradient of TWN-12 impinging on the wildlife mound.
Hydro Geo Chem concludes (HGC, 2009) that the presence of higher permeability
horizons within the nitrate/chloride plume (by analogy with the area near MW-4 in the
chloroform plume) would allow greater spreading of perched zone nitrate/chloride within
the applicable time frames. Hydro Geo Chem notes that the high hydraulic conductivity
estimated at TWN-16 indicates the possible existence of such a horizon, although such
a horizon does not appear to be penetrated by other TWN-series wells. However,
Hydro Geo Chem notes that additional data might reveal the presence of a zone
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 21
analogous to the chloroform plume near MW-4 that may have transported nitrate and
chloride over longer distances.
This scenario would explain the co-located nitrate and chloride in both the upper and
lower plumes. INTERA considers this to be the best explanation for the nitrate and
chloride plume that has been observed on and up-gradient of the Mill site.
3.3.4 Expected Future Migration
The nitrate and chloride are already being removed by pumping from the chloroform
remediation. The extent of future migration of the nitrate and chloride will depend upon
factors that include: 1) the rate of future mass removal by pumping, 2) perched zone
hydraulic gradients, 3) perched zone permeabilities downgradient of the nitrate and
chloride plume, and 4) natural attenuation processes including denitrification of nitrate
and hydrodynamic dispersion of both nitrate and chloride. Pumping of MW-4, MW-26
(TW4-15), TW4-19, and TW4-20 for chloroform remediation, directly removes nitrate
and chloride mass from the perched zone, and reduces the magnitude of the hydraulic
gradients in the downgradient portions of the plume. As a result of this pumping, nitrate
and chloride concentrations are reduced within the plume and the rate of downgradient
migration is slowed.
Figure 9 is a map showing the nitrate/chloride plume boundary superimposed over the
estimated combined chloroform capture zones of MW-26 (TW4-15), TW4-19, and TW4-
20, and the estimated capture zone for MW-4 (from HGC, 2009). A portion of the
southern half of the plume is currently outside the estimated capture zone. Although the
extent of the capture zone is expected to increase over time, including expansion to the
south, it is unlikely that complete hydraulic capture of the plume is achievable with the
current pumping scheme. However, pumping in the southern (downgradient) extremity
of the plume is impractical due to low permeability and low saturated thickness (HGC,
2005), as discussed below.
The estimated range of perched zone permeabilities over much of the area of the nitrate
and chloride plume is one to two orders of magnitude greater than estimates for areas
downgradient of the nitrate and chloride plume and the tailings cells as discussed
above. This reduction in permeability to the south and southwest is interpreted as a
"pinching out" of a coarser-grained, higher permeability zone identified during
installation of many of the temporary wells (HGC, 2005). The pinching out of this zone is
important in limiting the rate of downgradient migration of nitrate and chloride, in
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 22
stabilizing the plume boundaries, and in allowing natural attenuation to be more
effective in limiting plume migration.
The combination of relatively high permeability and relatively large saturated thickness
in the upgradient portions of the plume that make the productivity of the perched zone
high and allow relatively high nitrate and chloride mass removal rates via interim
pumping, is absent at downgradient wells such as TW4-4 and TW4-6. The combination
of relatively low permeability and small saturated thickness near these downgradient
wells makes pumping at these wells impractical. Because low permeability conditions to
the south and southwest, and flattening hydraulic gradients resulting from upgradient
pumping will reduce rates of downgradient migration, natural attenuation will likely be
effective in treating that portion of the plume that will remain outside hydraulic capture
(Attachment 2). Natural attenuation processes that will reduce concentrations are
primarily limited to denitrification and hydrodynamic dispersion that relies on mixing with
recharge and waters outside the plume lowering concentrations with distance.
As a result of ongoing nitrate and chloride mass removal by pumping, and natural
attenuation processes, the plume at present appears to be relatively stable. However it
will be necessary to collect additional data to assess stability over time.

4.0 CHARACTERIZATION OF THE FACILITY
As required by UAC R317-6-6.15 D 1. b., the characterization of the facility includes a
description of the following items.
4.1 Contaminant Substance Mixtures Present and Media of Occurrence
The contamination has been identified as a nitrate and chloride plume in the perched
aquifer at the Mill Site. The Source Report has analyzed potential contaminant
substance mixtures at the Mill Site and surrounding properties, identified to date, that
could have generated nitrate and/or chloride in the perched aquifer. The Source Report
summarizes nitrate and chloride compounds or sources that are present at the Site, the
uses of the compound, if the compound can generate nitrate and chloride, and if there
are off-Site sources.
4.2 Hydrogeologic Conditions Underlying and, Upgradient and Downgradient of
the Facility
Hydraulic testing of new monitoring wells TWN-1 through TWN-19 was conducted to
estimate perched zone hydraulic properties in the vicinity of each new well. This
information is detailed in an updated Site Hydrogeology and Estimation of Groundwater
Pore Velocities in the Perched Zone, White Mesa Uranium Mill Site near Blanding, Utah
(HGC, 2009) included in this Report as Attachment 5.
Slug test data were collected and analyzed using AqtesolvTM software. Estimates of
hydraulic conductivity range from 3.6 x 10 -7 cm/s at TWN-7 to 0.0142 cm/s at TWN-16.
Except for the hydraulic conductivity estimate at TWN-16, values are within the range
previously reported for the Site. Pore zone velocities along hypothetical pathways
through elevated nitrate/chloride areas have been calculated as approximately 0.55 ft/yr
to 7 ft/yr in the northeast area plume. Pore velocity for the Mill area plume is 23 ft/year.
4.3 Surface Waters in the Area
The Mill is located on White Mesa, a gently sloping (1 percent SSW) plateau that is
physically defined by the adjacent drainages which have cut deeply into regional
sandstone formations. There is a small drainage area of approximately 62 acres (25 ha)
above the Site that could yield surface runoff to the Site. Runoff from the mesa
discharges into an unnamed branch of Cottonwood Wash. Surface runoff from 624
acres of the Mill Site drains westward and is collected by Westwater Creek. Runoff from
another 384 acres drains east into Corral Creek, while the remaining southern portions
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 24
of the Site drain indirectly into Cottonwood Wash. Total runoff from the mesa is
estimated to be less than 0.5 inch annually (Dames & Moore, 1978).
With the exception of the wildlife ponds, which were made or maintained by DUSA to
divert birds and other animals from the tailings cells, there are no perennial surface
waters on or in the vicinity of the Mill Site. This is due to the gentle slope of the mesa on
which the Site is located. Sampling of these ephemeral surface waters in the vicinity is
possible only during major precipitation events (DUSA, 2007).
See Section 1.4 of the Reclamation Plan, Rev. 4.0 for further details on surface waters
in the area of the Mill.
4.4 Climatologic and Meteorologic Conditions in the Area of the Facility
The climate of southeastern Utah is classified as dry to arid continental. Climate in the
vicinity of the Mill can be considered semi-arid with average annual precipitation of
approximately 13.32 inches. The area receives two separate rainfall seasons: one from
August to October and the other from December to March. The mean annual relative
humidity is about 44 percent and is normally highest in January and lowest in July. The
weather in Blanding is typified by warm summers and cold winters and the mean annual
temperature is about 50.3 degrees Fahrenheit.
The predominant wind directions during 2008 were north-northeasterly. Northerly winds
are drainage winds occurring during the nighttime. The southerly winds are upslope
winds occurring during daytime hours. The annual mean wind speed was 3.5 m/s
(McVehil-Monnett Associates, Inc., 2009).
See Section 1.1 of the Reclamation Plan, Rev. 4.0 for further details on the climatologic
and meteorologic conditions in the area of the Mill.
4.5 Possible Sources of the Pollution at the Facility: Type, Location, and
Description
As discussed in Section 3, based on new well installation, the source of nitrate and
chloride contamination is believed to be off the DUSA property to the northeast. At this
point the municipal sewage plant discharge water used historically as Mill water makeup
appears to be the best candidate for the source of elevated nitrate and chloride in
groundwater.
The waste water treatment facility described in the Source Report is located several
miles upgradient of the Mill Site but discussions with Mill staff indicate that effluent from
Nitrate Contamination Investigation Report

that facility was allowed to flow to a pond (Frog Pond) near the Mill boundary where it
was subsequently piped to the northern-most Wildlife Pond at the Site and to another
holding pond on Site for Mill makeup water (Lawzy Lake, see Figures 6 and 7). The Mill
staff reports that this water had a bad odor and may have had a high sludge content.
Nitrate and chloride are commonly associated with wastewater treatment effluent
(McQuillan, 2004).
This potential source term was a high priority during this contamination investigation for
several reasons. The period of Mill use of water from the Frog Pond was from the mid
1980s to about 1991 or 1992 when it was replaced with water from Recapture
Reservoir. As documented in the Background Report (INTERA, 2007), groundwater
levels at the Site have been influenced by the Wildlife Ponds so we know that the head
in those ponds has been sufficient to drive infiltration to the water table.
The “slug” like character of the nitrate and chloride plume is consistent with a source
that has been removed. The distances from the northern-most Wildlife Pond and Lawzy
Lake to the centroid of the nitrate and chloride plume are approximately 2300 feet and
2100 feet, respectively. Assuming 26 years since nitrate/chloride laden water entered
the system, groundwater would have had to travel at an average velocity of 88 ft/yr from
the northern-most Wildlife Pond and 81 ft/yr from Lawzy Lake to account for the current
distribution of nitrate concentrations. The velocity of 88 ft/yr from the northern-most
Wildlife Pond is high relative to other values that have been calculated for the Site, but
possible given the high gradient in this limited portion of the Site due to mounding at the
wildlife ponds. Further, the eastern portion of the Site is known to have higher
permeability (consistent with the 88 ft/yr velocity required) than the western portion (see
the Chloroform Contaminant Investigation Report). The Lawzy Sump is even closer to
the plume.
For the above reasons Lawzy Lake, the Lawzy Sump, and the northern-most Wildlife
Pond are likely potential infiltration points for Frog Pond water. These potential
infiltration points have been addressed by installation of two monitoring wells. One
(TWN-3) was installed half way along a line between the north end of the Mill building
and Lawzy Lake. Analytical results of samples of groundwater from well TWN-3 show
29 mg/L nitrate and 106 mg/L chloride, indicate that this well may be near a potential
infiltration point. The other monitoring well (TWN-4) was installed on a line
approximately half way between the north end of the Mill building and the northern-most
Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 26
Wildlife Pond. Groundwater samples from TWN-4 contained 0.4 mg/L of nitrate and 11
mg/L chloride.
The northern-most Wildlife Pond was a stock watering pond for years prior to
construction of the Mill. The Historic Pond, which no longer exists, but was located
where the Mill’s sulfuric acid tank is currently located, pre-existed construction of the Mill
by several decades, tracing back possibly to the 1920s. Livestock can generate nitrate
in and around stock watering ponds as salt licks for livestock can generate chloride, and
the water head in the ponds could potentially drive those nitrates into the groundwater.
Therefore, livestock activity at these ponds had the potential to contribute nitrate and
chloride to groundwater but these mechanisms alone would be unlikely to generate
enough mass to account for the current mass of nitrate and chloride observed in
groundwater.
4.6 Groundwater Withdrawals, Pumpage Rates, and Usage Within a 5-Mile
Radius of the Mill
Two hundred sixty one groundwater appropriation applications, within a five-mile radius
of the Mill site (which includes a 2-mile radius from the nitrate/chloride plume), are on
file with the Utah State Engineer's office. A summary of the applications is presented in
Table 1.5-4 and shown on Figure 1.5-8 of the Reclamation Plan, Rev. 4.0. The majority
of the applications are by private individuals and for wells drawing small, intermittent
quantities of water, less than eight gpm, from the Burro Canyon formation. For the most
part, these wells are located upgradient (north) of the Mill site. Domestic water, stock
watering, and irrigation are listed as primary uses of the majority of the wells. It is
important to note that no wells completed in the perched groundwater of the Burro
Canyon formation exist directly downgradient of the site within the five-mile radius. Two
water wells, which available data indicate are completed in the Entrada/Navajo
sandstone, exist approximately 4.5 miles southeast of the site on the Ute Mountain Ute
Reservation. These wells supply domestic water for the Ute Mountain Ute White Mesa
Community, situated on the mesa along Highway 191. Data supplied by the Tribal
Environmental Programs Office indicate that both wells are completed in the
Entrada/Navajo sandstone, which is approximately 1,200 feet below the ground surface.
Insufficient data are available to define the groundwater flow direction in the
Entrada/Navajo sandstone in the vicinity of the Mill.

Nitrate Contamination Investigation Report
White Mesa Mill Site
December 30, 2009 27
The well yield from wells completed in the Burro Canyon formation within the White
Mesa site is generally lower than that obtained from wells in this formation upgradient of
the site. For the most part, the documented pumping rates from on-site wells completed
in the Burro Canyon formation are less than 0.7 cubic feet per second. Even at this low
rate, the on-site wells completed in the Burro Canyon formation are typically pumped
dry within a couple of hours.
This low productivity suggests that the Mill is located over a peripheral fringe of perched
water; with saturated thickness in the perched zone discontinuous and generally
decreasing beneath the site, and with conductivity of the formation being very low.

5.0 DATA USED AND DATA GAPS
Data used for this CIR consists of existing data and new data collected specifically for
the nitrate and chloride investigation. Data collected for use in this CIR, are included in
the Initial Nitrate Monitoring Report (Attachment 3). The Initial Nitrate Monitoring Report
includes laboratory analytical reports and QA/QC reports.
Data gaps were encountered as drilling and field sampling began. These gaps were
addressed by installing additional wells as needed.

6.0 ENDANGERMENT ASSESSMENT
As discussed above, the nitrate/chloride contamination appears to be from a source (the
Frog Pond) upgradient of the Mill property, which was not caused or contributed to by
Mill activities. DUSA has taken the position that the responsibility for the contamination
should not be attributed to the Mill, and DUSA should not be required to prepare a CAP
for contamination resulting from a source off of its property.
However, were a CAP to be required, and were such a CAP to propose standards
under UAC R317-6-6.15F.2 or Alternate Corrective Action Concentration Limits that are
higher than the applicable State of Utah Groundwater Quality Standards, an
endangerment assessment would be performed. The endangerment assessment would
contain any risk evaluation necessary to support a proposal for a standard under UAC
R317-6-6.15F.2 or Alternate Corrective Action Concentration Limits that are higher than
the groundwater quality standards. The schedule for completion of any such
endangerment analysis would be agreed upon prior to commencement of the analysis.

7.0 PROPOSED CORRECTIVE ACTION PLAN UAC R317-6-6.15 (D)
As discussed above, the nitrate/chloride contamination appears to be from a source (the
Frog Pond) upgradient of the Mill property, which was not caused or contributed to by
Mill activities. DUSA has taken the position that the responsibility for the contamination
should not be attributed to the Mill, and DUSA should not be required to prepare a CAP
for contamination resulting from a source off of its property.
However, were a CAP to be required, such a CAP would include an explanation of the
construction and operation of the proposed corrective action, addressing the factors to
be considered by the Executive Secretary as specified in R317-6-6.15.E and would
include such other information as the Executive Secretary may require. It would also
include a proposed schedule for completion of the proposed corrective action.

SUBJECT:· Nitrate Contamination Investigation and Corrective Action Plan, White Mesa
Uranium near Blanding. Utah. Request for Voluntary Plan and Schedule to
Investigate and Remediate.
Dear Mr. Frydenlund:
On September 16, 2008 the Utah Division of Radiation Control (DRC) sent an bye-mail request
for a meeting with DUSA concerning nitrate concentrations that exceeded the Utah Ground Water
Quality Standard (GWQS) of 10 mgIL at the White Mesa Uranium Mill (facility) near Blanding.
DRC attached a draft letter documenting DRC finilings concerning the nitrate concentrations
exceeding the GWQS. A meeting was held by a conference call with DRC and DUSA
representatives on September 24, 2008. In this meeting both parties agreed that:
1) Nitrate concentrations have exceeded the GWQS in the groundwater at the facility in five
monitoring wells, most of which are not located within the confines of the known
chloroform groundwater plume (MW-30, MW-31, TW4-22, TW4-24, and TW4-25).
2) For the monitor wells in question multiple samples in each have been found in excess of
the nitrate GWQS, beginning as early as June 22, 2005 (2nd quarter 2005 monitoring
event).
3) The nitrate plume has migrated in a different direction than the chloroform plume.
4) The physical boundaries of the nitrate plume are not fully defined.
5) The source(s) of the nitrate contamination are currently unknown.

Source Review Report (Tischler, 2009)

MEMORANDUM

To: Denison Mines (USA) Corp.

From: Jo Ann Tischler

Date: December 30, 2009

Subject: Source Review Report for Nitrate and Chloride in Groundwater at the
White Mesa Mill

Introduction

In correspondence dated September 15 and September 30, 2008. At that time, the DRC
noted that on a review of the 13 quarterly groundwater monitoring reports for the White
Mesa Mill (Mill), submitted by Denison Mines (USA) Corp. (Denison) to DRC since the
second quarter of 2005, groundwater nitrate levels had exceeded the State water quality
standard of 10 mg/L in certain monitoring wells at the Mill site. Specifically, DRC noted
that:

1. Nitrate concentrations have exceeded the Ground Water Quality Standard
(GWQS) in the groundwater at the facility in five monitoring wells, most of
which are not located within the confines of the known chloroform groundwater
plume (MW-30, MW-31, TW4-22, TW4-24, and TW4-25);
2. For the monitor wells in question multiple samples in each have been found in
excess of the nitrate GWQS, beginning as early as June 22, 2005 (2nd quarter 2005
monitoring event);
3. The nitrate plume has migrated in a different direction than the chloroform plume;
4. The physical boundaries of the nitrate plume are not fully defined; and
5. The source(s) of the nitrate contamination are currently unknown.

A map indicating the location of all monitoring wells under the Mill’s Groundwater
Discharge Permit (GWDP) and chloroform investigation, which includes the five
monitoring wells in question, is attached to this report as Figure 1. A map indicating the
1st Quarter 2008 water levels and direction of groundwater flow in the perched aquifer is
attached to this report as Figure 2.

In correspondence dated December 1, 2009, the Utah Division of Radiation Control
stated their observation that “an apparent chloride plume is in concert with the nitrate
contamination plume” at the white Mesa Mill. The observation was based on data from
chloroform investigation wells and tailings cell compliance wells during the fourth
quarter of 2008 and the first quarter of 2009. DRC’s letter included a nitrate and chloride
plume map. DRC noted that chloride concentrations ranged from 113 to 1010 mg/L
inside the 100 mg/L iso-concentration line.

DRC has recommended that Denison address and explain the chloride concentrations in
the nitrate Contamination Investigation Report (CIR) that is due to DRC, on or before
January 4, 2010.

My report of November 19, 2008 addressed my findings and conclusions regarding
sources of nitrate at, and proximal to, White Mesa Mill. The purpose of the current
report is to perform an evaluation of the “type, location and description of possible
sources of pollution at the facility,” which is required by R317-6-6.15b.(4) to be included
in the CIR. This report expands the analysis in the November 19, 2008 report to address
sources of groundwater chloride, as well as potential sources that may result in the
presence of both nitrogen and chloride.

To perform this evaluation, I have considered:

1. What are the current and historic sources of nitrogen-bearing chemicals
and biological nitrogen at the Mill?

2. What off-site sources of chemical and biological nitrogen exist within
proximity of the Mill?

3. What are the current and historic sources of chloride-bearing chemicals at
the Mill?

4. What off-site sources of chemical chloride exist within the proximity of
the Mill?

5. Do mechanisms exist for the nitrogen and chloride to reach groundwater?

6. Do mechanisms exist for the nitrogen to reach groundwater as nitrate?

7. Are the known volumes and concentration of the sources consistent with
ongoing nitrogen and chloride presence in groundwater?

1.0 Basis and Limitations of this Evaluation

This evaluation was limited to a qualitative process source review. That is, it considered
a broad range of nitrogen and chloride sources present on or in the vicinity of the Mill
and narrowed them down to those most likely to affect groundwater. The review did not
limit the potential sources based on quantitative factors in groundwater hydrogeology or
geochemistry.

The evaluation in this report is based on the following information:

1. Interviews with Denison corporate staff during October 2008, to gather
information on nitrogen-bearing materials used or present on site throughout the
Mill’s operating history.
2

2. Interviews with Denison corporate staff during October 2008, to gather
information on historical use of pits, ponds, landfills, and offsite water sources at
the Mill.

3. Interviews with Denison corporate staff during December 2009 to supplement
previous operations information to address chloride, as well as nitrate, sources.

4. Current and historic site maps provided by Denison corporate staff.

5. The Mill’s process and equipment description from Denison’s Radioactive
Materials License renewal application dated February 2007.

6. Tailings solution sample data provided by Denison corporate staff.

7. Reagent, Laboratory Chemical Inventory, and Petroleum Products tables from the
White Mesa Mill Spill Prevention, Control, and Countermeasures (SPCC) Plan
(2001).

2.0 Overview of Environmental and Human (Anthropogenic) Nitrogen Sources

In both the natural and industrial environments, nitrogen exists in three chemical forms:
either as free nitrogen gas (N2), “fixed” in inorganic compounds or “bound” into organic
compounds, as discussed below.

2.1 Biological Nitrogen Cycle

Apart from free atmospheric nitrogen (gaseous N2), nitrogen exists in the natural
environment in four chemical forms:

• Organic nitrogen (urea, uric acid, amines, amino acids, nucleic acids,
alkaloids, proteins, etc.);
• Inorganic free ammonia, that is present in equilibrium between its non-ionic
form (NH3) at high pH, and ionized form (NH4OH) at neutral and low pH;
• Inorganic nitrite, an intermediate oxidized form (NO2); and
• Inorganic nitrate, a stable oxidized form (NO3).

Nitrogen is ubiquitous in the living environment and is part of the living tissues, digestive
wastes, and decomposition products of every living thing on the earth’s surface. As a
result, there are many natural sources that mobilize nitrates into surface water and many
mechanisms for nitrates to enter groundwater.

Nitrogen is continuously converted and recycled through the biosphere in a series of
processes that comprise the nitrogen cycle. The wastes from living things and the
proteins in dead plant and animal tissues are decomposed by ammonification bacteria to
form ammonia. Specialized nitrifying bacteria convert the available ammonia to nitrite
and/or nitrate in aquatic environments and soils. Nitrite is relatively short-lived in water
and hydrated environments because aquatic bacteria convert it rapidly to nitrate.
Organisms such as fungi and denitrifying bacteria use the nitrates as a source of oxygen,
releasing the bound nitrogen back to the atmosphere as gaseous nitrogen.

In aquatic environments, the least stable form of nitrogen in water is ammonia. In
oxygenated aquatic environments, it is readily converted to nitrite and nitrate. In oxygen-
deficient waters it may be converted to nitrogen gas and hydrogen ions.

2.2 Anthropogenic Nitrogen

Nitrogen compounds are some of the most widely synthesized, converted, and consumed
materials in every human industrial, commercial, and domestic activity. Human activity
introduces nitrogen into the environment from four major types of sources:
4

• Agricultural;
• Combustion-related;
• Sewage and septic-related; and
• Industrial chemicals.

Agricultural

By far the largest source of nitrogen compounds introduced to the environment by human
activity are from agricultural sources. Per the US EPA, the largest loads of ammonium
and nitrite/nitrate nitrogen reach the environment from agricultural, domestic and
commercial runoff to surface water bodies and infiltration to groundwater from overuse
of fertilizers, as well as feedlots, cattle yards, slaughterhouses and dairies. In the western
US particularly, nitrate/nitrite overloads from agricultural sources far outweigh by several
orders of magnitude all the chemical/industrial loads to most surface receiving waters.

Combustion

The second largest source is the combustion of fossil fuels, resulting in atmospheric
nitrogen both from the nitrogen bound in the fuel (particularly in coal) and the conversion
of atmospheric nitrogen to oxygenated compounds at combustion temperatures in motor
vehicles, power plants, boilers, incinerators, kilns, and other fired heaters. In stationary
equipment, depending on the efficiency of combustion, some nitrate may remain bound
in compounds in the resulting fly ash and/or bottom ash.

Per even the oldest literature on the topic, all coal sources worldwide average from 1.0 to
1.5 percent (10,000 to 15,000 ppm or 10,000,000 to 15,000,000 ppb) bound nitrogen.
More modern data indicates the range to be as wide as 0.5 to 2 percent. Nitrogen in coal
is generally bound into complex heterocyclic molecules (ring compounds containing both
carbon and nitrogen). The nitrogen content of ash resulting from coal combustion varies,
and may have even higher levels, depending on the type of burner and type of emissions
control. Both stack gases and residual ash exhibit nitrogen in oxidized form, as
nitrite/nitrate. In fact, historically, the earliest industrial attempts at synthesis of
ammonia and nitrate compounds for the chemical industry were based on converting this
nitrogen content of coal.

Sewage and Septic Sources

The third largest sources are from septic systems and sewage plant byproducts.
Ubiquitous and relatively uncontrolled leach fields and septic systems load nitrogen in a
variety of compounds and forms (from sanitary wastes, food wastes, detergents, and
cleaning chemicals) directly to surface and subsurface soils. Both the US EPA and US
Geological Survey consider septic systems to be one of the largest uncontrolled threats to
surface water and drinking water quality nationwide. Recent source investigations
published by Dennis McQuillan at the 2004 National Onsite Wastewater Recycling
Conference for nearly 1,200 water wells in New Mexico indicated that, in that setting,
5
on-site septic systems contaminated more acre-feet of groundwater, and more public
supply systems, than all other sources in the region combined.

Land disposal or land application of sludges and solids from aerators, digesters, and other
municipal sewage treatment plant processes, which convert, dewater, and concentrate
multiple forms of nitrogen from treated influent water have a comparable or greater effect
on receiving soils. Wastewater plants also add nitrogen to the atmosphere through the
off-gases from driers, digesters and open process equipment.

Table 1 presents data on nitrate levels in influent liquids and residual solids from a wide
range of municipal sewage treatment plants as studied by Metcalf and Eddy. Both
primary sludges and digester sludges range as high as 60,000 mg/L (ppm) of total
nitrogen.

Historic Sewage Treatment Practices

Very little specific information is available regarding the Blanding municipal sewer
treatment plant or Publicly-Owned Treatment Works (POTW). However, general
historic information on wastewater management history provides some idea of what
operations were likely in a rural POTW which was already in operation before the
construction of White Mesa Mill in the late 1970s, and may have been in operation as
early as the first decades of the twentieth century.

Data from the USEPA wastewater treatment inventory indicates that in 1945, only 5,786
sewer treatment plants operated throughout the entire US. By 1974, this number had
increased to 21,011. These numbers indicate that prior to and during this period, a large
number of communities managed sewage waste by untreated direct discharge to surface
water bodies, deep wells, land disposal areas, and septic fields. The data also indicates
that as recently as 1974, primarily in rural areas, 78 percent of the existing treatment
plants had less than 1 million gallons per day (MGD) capacity and 14 percent still had no
secondary treatment (no biological or chemical processes to remove organic content). Of
all 21,011 plants of all types operating in 1974, 95 percent had no post-treatment nitrogen
or chloride removal.

According to the US EPA 1974 Needs Survey, the most common type of treatment
design in facilities of less than 1 MGD, and in many above that size, was aerobic
stabilization ponds. This type of treatment attempts to increase the oxygen content
available to treatment bacteria by aeration and mixing, or by aeration and mixing coupled
with algae growth for additional oxygen. These types of facilities are defined as
suspended growth treatment processes. In suspended growth treatment, the biomass is
mixed and suspended throughout the wastewater. After microbial contact and treatment,
the majority of the biomass (bacteria and algae) exits the pond with the treated water. If
there is little or no downstream solids removal processing, nearly the entire solids mass
exits with the treated water.

6
It should also be noted that biological treatment, whether suspended or fixed type, is
designed primarily to convert, not remove, organic carbon and nitrogen content. While
the sewage carbon and nitrogen compound levels are reduced during bio-treatment, they
are converted into an increase in biomass (microbes and algae). Unless solids reduction
steps follow the bio-treatment, nearly the same carbon and nitrogen levels exit in the
treated water, just in different forms.

Suspended growth systems are far more prevalent in rural settings than the more
sophisticated attached growth processes (trickling filters, rotating biological contactors,
and packed bed reactors) used in large urban plants, in which the biomass is attached to
an engineered surface, wastewater passes through the mass for bio-treatment, and exits
with lower suspended and dissolved solids content.

Application of a Time-Relevant Case Study

For two years during the late 1970’s, I participated in a sampling and analysis study of
municipal sewage treatment plant outfalls and nearby receiving waters in a non-urban
area of northern New Jersey. The study was part of an ongoing program to assess
nitrogen-based pollutant loads and other sources of chemical and biochemical oxygen
demand exiting from small-community secondary treatment plant discharges into the
upper reaches of the Hackensack Meadowlands. Water samples from drainages that
received flows from industrial/commercial outfalls just upstream and downstream were
also sampled for comparison. The work was published by Dr. R. Trattner in “Water
Quality in a Recovering Ecosystem” in 1978. While the receiving environments differed
from the Blanding area situation (surface water versus soil and groundwater), the
wastewater treatment plant sources in New Jersey were of comparable vintage and type
to warrant the extension of some observations to the Blanding situation.

The most significant observation from two years of monthly monitoring was that with
respect to effluent nitrate, the plants were generally in upset conditions more often than
they were in controlled conditions. The upsets included the periodic overtopping of
settling and solids removal equipment and discharge of high total suspended solids
(TSS), indicating that bio sludge was exiting via the effluent water instead of through the
solids management circuit.

The other significant observation was that the receiving waters outside the sewer plant
outfalls exhibited amine and nitrate levels orders of magnitude higher than receiving
waters near the industrial outfalls, including outfalls from nitrogen-wasting processes
including tanning and dyeing, leather finishing, rendering, and meat-packing plants.

While the above findings resulted from monitoring of aqueous waste to surface water
discharges (not aqueous waste to soil to groundwater), the indications are consistent with
the USEPA and McQuillan opinions regarding the relatively greater importance of
sewage nitrogen than industrial nitrogen as an environmental pollutant.

Industrial Chemicals

Industrial chemicals and chemical wastes are generally a smaller source of nitrogen than
those identified above. In the US chemical industry, non-gaseous industrial nitrogen
compounds typically reach the environment through:

• Industrial discharges into municipal wastewater treatment systems
followed by treatment and water discharge into surface water bodies;
• On-site wastewater treatment to permit-driven standards and discharge
into surface receiving waters;
• Land disposal of the solids and sludges from either of these types of
treatments; and
• Direct spills of nitrogen-bearing chemical products or chemical/industrial
wastes.

As mentioned above, however, in biotic environments, nearly all inorganic nitrogen
compounds, upon exposure to water and oxygen, are readily converted to nitrites, then
nitrates, by ubiquitous natural biochemical processes in surface water bodies and runoff
channels. Therefore, nearly any industrial spill or release of inorganic nitrogen
compounds that is exposed to atmospheric oxygen and soil or water bacteria will
eventually be converted to nitrate. For this reason, ammonia nitrogen compounds that
reach groundwater through surface spills will eventually be exhibited in groundwater as
nitrate, not ammonia, nitrogen.

3.0 Overview of Natural and Anthropogenic Chloride Sources

3.1 Natural Sources and Properties

The chloride ion is present in one of the most ubiquitous materials on earth – seawater
and natural brines. In inland areas, inorganic chloride compounds may be present in
regional geologies as residual salts and mineral deposition from ancient inland seas.
Chloride as sodium chloride is present in biotic systems almost universally as a dilute
saline component of cellular fluids in both micro- and macro-species.

Chloride is a polar ion that in many forms (chlorates, chlorites, hypochlorites, chlorine
dioxide, metal chlroides) is a strong oxidizer, generally destructive to both microscopic
and macroscopic life. Since the late 19th century chlorine-containing bleaches and
preparations have seen increasingly widedspread use as germicides and sterilants,
beginning even before their ability to destroy microbes by penetration and disruption of
their cell membranes was understood.

However, unlike the plethora of nitrogen-bearing chemicals and biochemicals in biotic
systems, few or no organo-chlorine compounds exist in nature. Organo-chlorine species
(arochlors, chloroohenols, dioxins, chloramines, chlorinated olefins, chlorosulfonic
compounds) are also disruptive to biotic processes, hence their extensive use during the
8
20th century of chlorinated organics as tissue-soluble pesticides and herbicides.
Overwhelmingly, the chloro-organic compounds present in the natural environment today
are the products of synthetic organic chemistry and/or the secondary chlorination of
synthetic and natural organic chemicals in wastewater treatment settings.

3.2 Anthropogenic Sources

Sewage and Septic Sources

Chloride is a relatively non-reactive solute that occurs in all sewage. It enters sewage
from two sources – household chemicals and wastes discharged into the sewer system,
and additional chloride added during sewage treatment. Chloride-bearing household
chemicals include primarily bleaches, cleaners, and water softener salts used and
disposed in relatively large volumes, and pharmaceuticals, solvents and pesticides
generally present in domestic wastewater at very low levels. US EPA data from the past
decade indicates that domestic water entering a typical household increases in chloride
content from 20 to 50 times before it reaches the sanitary sewer or septic sump. For
households using salt-regenerated water softeners, this ratio of increase may be one or
more orders of magnitude higher.

Data from the same period indicates that from tap water to the effluent of a sewage
treatment plant, chloride levels increases an average of 74 times and up to 200 times.
That is, the municipal treatment of domestic wastewater not only does not remove the
chloride ion prior to discharge, it adds significantly to its concentration. Chloride
addition in wastewater treatment is discussed below.

Disinfection in Sewage Treatment Plants

Chlorine, in one of several forms, is the most common disinfectant in wastewater
treatment throughout the world. Depending on plant size, safety considerations, and
economic factors, it is applied either as free chlorine gas, sodium hypochlorite, calcium
hypochlorite, and/or chlorine dioxide. Chlorine in one of these forms is added to
generate an excess of solubilized chlorine, in the form of hypochlorous acid.

Chlorine reacts first with inorganic ions in biotreated sewage to form chloride ions. The
effluent from most wastewater treatment aerobic steps contains significant amounts of
nitrogen in either the ammonia form, or as nitrate if the plant is designed to achieve
nitrification. As additional chlorine is added, and the inorganic demand is satisfied, free
chlorine reacts readily with the ammonia content of bio-treated wastewater to form
mono-, di- and tri-chloramines, which act as disinfectants. Some chloramines are
eventually oxidized to nitrous oxide and nitrogen.

The point beyond oxidation, at which all the reaction demands have been met and all
added chlorine remains as free chlorine, is referred to as the break point. The majority of
chlorinated compounds formed up to the breakpoint, other than the nitrous oxide and
nitrogen gas, precipitate as solids and increase the sludge volume. The goal of
9
wastewater plant chlorination is to add chlorine far in excess of the breakpoint over the
process from biotreatment through discharge. As a result, treated effluent may contain
heavy loads of excess chlorine, to ensure disinfection. Metcalf and Eddy indicate that
wastewater plants running optimally may have residual chlorine levels (all forms) in
effluent from the biotreatment step only, as ranging from less than 1 ppm to as much as 7
ppm. They do not report chlorine addition levels for the subsequent steps of the process
prior to discharge, which is where the heaviest chlorine use takes place. If the plant does
not have a de-chlorination process step, the chlorine residuals remain in the discharged
effluent. The levels of chloride and chlorinated compounds that exit the plant during
upset conditions, or when impoundments overtop and sludges and sludge solutions exit
the plant, are significantly higher than what is exhibited at the exit of the biotreatment
step.

Other Uses in Typical Wastewater Plants

Chlorine is added widely throughout other parts of typical sewage plants, also adding to
the effluent chloride load. In the collection area it may be applied for slime growth
control, corrosion protection, and odor control. In the treatment section it may be
applied for grease removal, BOD reduction, oxidation of ferrous sulfate, filter process
control, reduction of sludge bulking, oxidation of supernatant form digesters and control
of foaming in digesters, ammonia oxidation, odor control and oxidation of bio-refractory
(non-degraded) compounds. It is also heavily used in the disposal section of most plants
for disinfection (bacteria reduction) and odor control.

In the New Jersey case study for example, 10 of the 11 monitored sewer plant designs
were based on aerated stabilization ponds, and one was an anaerobic Imhoff tank design.
Typical of the era, the Imhoff plant and nine of the aerobic plants used inorganic forms of
chlorine, primarily hypochlorites, at multiple points in the process for odor control, slime
and microbe control, corrosion control, general disinfection and microbe destruction prior
to effluent discharge. One aerobic plant used a UV/bromine treatment for the same
purpose. Also typical of the era, 10 of the 11 had no tertiary treatment for nitrogen
removal, and none of the 11 had any polishing treatment for chloride or bromide removal.

Industrial Chemicals

The production of chlorine (gas), primarily via the hydrolysis of natural brines, is one of
the most important heavy chemical industries, ranking as one of the top three chemicals
produced in the US, both by tonnage and dollar value. Chlorine’s organic and inorganic
chloride products are used in a wide spectrum of chemical processes including pulp and
paper, solvents and degreasers, polymers and plastics, pesticides, refrigerants, bleaches
and sanitizers, heat transfer fluids, dry cleaning, military chemical weapons (nerve and
blister agents), road de-icing, and metallurgy.

Industrial chlorine or chloride enters the environment via the same routes as described for
industrial nitrogen, above, that is, wastewater treatment associated with chemical
manufacture or use, or direct spills of chemical products.
10

In industrial settings, the presence of chloride in environmental media may be affected
significantly by all of the industrial and domestic use of inorganic chlorides (salts),
synthetic chemicals, and sewer treatment sources. In rural and non-industrial settings,
where the presence of synthetic industrial chlorinated chemicals are present at household
(or ranch or farm) sized quantities, the effects of inorganic salts (salt licks, road deicing,
water softeners) and sewage treatment sources, tend to predominate.

4.0 Potential Sources of Groundwater Nitrate

Table 2a provides a summary of industrial, commercial, agricultural and municipal
sources of nitrogen compounds from which potential candidate sources for the Mill
nitrogen can be elicited. The list does not itemize every scientifically known nitrogen
compound. That is, it does not include short-lived or rare compounds synthesized solely
for research purposes. For brevity, in many cases the list presents a class of compounds
or types in lieu of naming every species in the category.

The upper section of the table identifies those compounds and classes of materials that
could be expected to be present on the Mill site or in the vicinity of the Mill. The lower
section completes a broader survey of compounds and sources and indicates why they are
not, or are likely not, present at or proximal to the Mill.

The potential sources are evaluated and discussed in more detail in the sections below.

4.1 On-Site Nitrate Sources at the Mill

The Mill commenced operations in May 1980, and operated on a campaign basis at near
full capacity on conventional ores from the Colorado Plateau (uranium-vanadium ores)
and Arizona Strip (uranium ores) until 1991. The Mill also processed conventional ores
for short durations in 1995 from the Arizona Strip, in 1999 from the Colorado Plateau,
and in 2008 and 2009 from the Henry Mountains complex and the Colorado Plateau.. In
addition, commencing in 1993, the Mill processed finite volumes of alternate feed
materials from several Formerly Utilized Sites Remedial Action Program (FUSRAP)
sites and from other uranium and metal industry sources. As indicated in my evaluations
of alternate feed characteristics since 1997, alternate feed materials have never been an
appreciable source of nitrogen compounds, never exhibiting more than ppm levels in
finite volumes of materials that have either been stored in closed containers or have
remained on the ore pad less than a few months before processing. Based on this history,
the potentially larger sources of nitrogen introduction into the Mill likely preceded and
were independent of the alternate feed program.

Tables 3a and 3b provide integrated lists of nitrogen-bearing laboratory and bulk reagents
stored and used on the Mill site. Potential sources of groundwater nitrogen from among
these and other materials on the Mill site are discussed below.

11
Septic Leach Fields

As mentioned above, both the US EPA and US Geological Survey consider septic
systems to be one of the largest sources of nitrate loads to surface water and groundwater,
nationwide. The Mill has several operating or historic septic leach fields. The locations
of these leach fields are indicated on the attached Figure 3. Some key facts relating to
these leach fields are discussed below.

The Former Office Leach Field (located south east of the Mill’s Administration
Building) is no longer in use. It was used in the early 1980’s to accept septic waste
from the Mill’s administration building. For a short period of time, it also accepted
wastes from the Mill’s chemical and metallurgical laboratories, until Cell 1 was
competed in 1981;

The Scale House Leach Field (located south west of the Scale House) may no longer
be in use (see discussion under Main Leach Field below). It was used until the mid
1980’s to accept septic waste from the restroom in the Scale House. It also accepted
laboratory wastes from the temporary laboratory in the Scale House from around
1977 until the main laboratories in the Mill’s administration building were
commissioned in 1980;

The Cell 1 Leach Field (located just east of Cell 1) is currently used to accept septic
wastes from the restrooms in the Mill’s Central Control Room and SX Building;

The SAG Leach Field (located just north of the Mill building) was used to accept
septic waste from the restroom in the Shifter’s Office near the SAG Mill. It is
currently operable, but that office and restroom have been closed since the 1999 Mill
run. The toilet at that location is currently not operable.

The Main Leach Field (located east of the ore pad) was put into use in the mid 1980’s
and is currently in use. Septic wastes from the restrooms in the Administration
Building, the Maintenance Shop, the Warehouse and the Changing/Shower rooms are
piped to the Sewage Vault, located under the current yellowcake storage area, where
it is pumped to the Main Leach Field. There is a pipe from the Scale House to the
Sewage Vault. However, effluent is not entering the Sewage Vault from that pipe,
which suggests that the waste from the Scale House restroom is still being discharged
into the Scale House Leach Field, or that there could possibly be a breach in the pipe
and the Scale House waste may be discharging at that point.

Two of these leach fields (the Scale House Leach Field, and the Former Office Leach
Field) are believed to be the source of the existing chloroform contamination at the Mill,
due to the historic disposal of laboratory wastes in those leach fields (see the discussion
below relating to Mill Laboratories). Nitrate, along with chloroform, has been sampled in
all of the chloroform investigation wells as part of the chloroform investigation.
Attached as Table 4 to this report is a list of all chloroform and nitrate sample results
from the chloroform investigation, as taken from the Mill’s most recent Chloroform
12
Monitoring Report. Attached as Table 5 to this report is a table prepared by DRC and
attached to the draft September 15, 2008 Request for Additional Information, which
shows nitrate concentrations in monitoring wells within the chloroform contamination
plume and highlights in yellow nitrate concentrations in those wells that have exceeded
the GWQS of 10 mg/L. Table 6, provided by Denison Corporate staff, is a tabulation of
chloride and nitrate data from Mill monitoring wells and test wells collected during the
last quarter of 2009.

In addition, as described below, prior to the construction of Cell 1, the Mill laboratories
have also discharged a variety of non-septic nitrogen-bearing chemical solutions to
several of the leach fields.

From this information, it is clear that the Scale House Leach Field and Former Office
Leach Field have contributed nitrate to groundwater at the site. It is possible that the
other septic leach fields alone, or in conjunction with these two leach field, have given
rise to or contributed to the nitrate contamination that is the subject of this report. A
number of these other leach fields are either upgradient or cross-gradient to such nitrate
contamination. In particular, the SAG Leach Field is located upgradient of the nitrate
plume. The Main Leach Field has been the Mill’s main septic leach field since the mid
1980’s, and is located upgradient/crossgradient of the nitrate plume.

Because the SAG Leach Field is upgradient of the nitrate plume and the Main Leach
Field is located upgradient/crossgradient of the nitrate plume, they should be given a high
priority in the Sampling Plan.

Frog Pond

Until the early 1990s, process water for the Mill was limited to the deep water supply
wells on site, and the Mill sought additional sources of process water. Recapture
Reservoir was not constructed until 1988-1989, and the pipeline from Recapture
Reservoir to the Mill was not completed until around 1991-1992. From the mid 1980s
until the Recapture Reservoir water was first piped to the Mill in 1991-1992, effluent
from the regional sewage treatment plant, north-east and upgradient of the Mill site
served as an additional water source for Mill operations.

The two ponds associated with the water treatment facility are unlined. Effluent and
seepage from the water treatment plant flows to Corral Canyon, just east of the Mill site.
This flow was dammed by local ranchers prior to construction of the Mill to form a pool
just north of the entrance to Corral Canyon. This pool exists today and is referred to as
the “Frog Pond”. Discussions with personnel at the City of Blanding have confirmed that
the water in the Frog Pond is fed by the water treatment facility.

At the Frog Pond an electric pump carried the water for use at the Mill via an
underground pipe at the rate of about 200 gallons per minute (gpm). Just north of the
Mill’s restricted area, the water could be diverted to either the northern most wildlife
pond (the “Upper Wildlife Pond”) or to a secondary pond, referred to as “Lawzy Lake”.
13
At the Upper Wildlife Pond a diesel pump was activated when water was needed in the
Mill. Water was then pumped from the Upper Wildlife Pond to the Mill’s pre-leach
tanks, which acted as water storage for the Mill. The water in Lawzy Lake was gravity
fed via a pipe to a sump (the “Lawzy Sump”) within the restricted area. Once the water
reached the Lawzy Sump, it was pumped via a pipe to the pre-leach tanks for water
storage. None of the ditches, the Upper Wildlife Pond, or Lawzy Lake are lined.

The locations of the water treatment ponds, the Frog Pond, the Upper Wildlife Pond and
Lawzy Lake are shown on Figure 4. The various ditches and pipelines connecting Lawzy
Lake to Lawzy Sump, the wildlife ponds to the SAG leach field, and the sewage vault to
the Main Leach Field are also shown on the attached Figures 5.

Water was pumped from the Frog Pond to the Upper Wildlife Pond and/or Lawzy Lake
as needed during operations. During periods of full operations, those ponds were filled
with water from the Frog Pond several times per year, and sometimes several times per
month.

Anecdotal evidence suggests that the waste treatment facility experienced upsets and
leakages in their post-treatment sludge ponds, resulting in discharges of sewage sludge
and/or sludge-laden water from the plant to the Frog Pond. The sludge-laden waters
exhibited a septic/sewage odor in the channel, in each ponded area, in the Lawzy Sump,
and where it entered the uranium leach circuit. Various Mill staff described adding the
water to the Mill process at rates varying from 25 to 200 gpm depending on the specific
needs of the ore run (at normal operating rates the Mill consumes and evaporates
approximately 650 gpm). This use of pond water was finite and lasted until about 1992,
when Recapture Reservoir water became available.

As discussed above, sanitary sewage byproducts are extraordinarily high in nitrates and
other nitrogen-bearing compounds concentrated in the precipitation, concentration and
digestion steps of the sewage treatment process. As mentioned in Table 1, typical sludge
exhibits nitrogen contents ranging up to 60,000 ppm. Because sewage sludge has already
undergone physical/chemical treatment (primary treatment) and, in some plants, bio-
oxidation (secondary treatment), the majority of the nitrogen content is present in the
nitrated form.

This source review did not include any study of the size, process configuration or
operational practices of the regional sewage treatment plant at the time of reuse of its
effluent at the Mill. It is not known whether the plant had primary (suspended solids),
secondary (biological treatment and disinfection), or tertiary (color, odor and
nitrate/chloride conversion and polishing) treatment. Based on the location and time
period under consideration it is likely the plant was limited to primary and/or secondary
treatment. The data in Table 1 is relevant and representative because it represents an
overview of nationwide treatment plants, including some of greater sophistication,
collected in the late 1970s through 1980, a period when the Blanding treatment plant
operated but the Mill was not yet constructed.

14
Although the Mill’s use of sewage-based water ceased in the early 1990’s, sediments and
residuals from the Frog Pond and transfer ponds remained and may still be detectable by
soil sampling or additional groundwater sampling. However, nitrate concentrations
would be expected to diminish significantly over time due to natural biodegradation, and
current nitrate levels would be expected to be lower than when these structures were
actively used.

This source could be the sole or a significant contributor to the nitrate plume at the Mill
site, and is upgradient to the most upgradient well in question (TW4-25). Furthermore,
the fact that the water from the Frog Pond was conveyed on the surface via pipeline to the
Mill site, could explain why high nitrate concentrations have not been observed in the
Mill’s most upgradient monitoring wells, MW-1, MW-18 and MW-19, as noted by DRC.

For these reasons, the Upper Wildlife Pond, Lawzy Lake and the Lawzy Sump are likely
sources of nitrate in on-site groundwater.

Fly Ash Pond

From 1980 to 1989, the Mill used a coal-fired steam boiler for operations. Fly ash and
bottom ash from combustion of bituminous Colorado Plateau coal were disposed of
primarily in tailings Cell 2. However, the ash disposal system did not always work as
intended, due to the high clinker volume in the ash. In upset situations, the fly ash was
disposed of in a pit referred to as the “Fly Ash Pond” that was located just north of TW4-
24. The Fly Ash Pond was originally built to hold construction water. The location of
the Fly Ash Pond is indicated on Figure 3.

The Fly Ash pond was located in the area of the Mill close to tailings Cell 1 that was
designed to catch surface runoff from the site and direct it into the tailings cells, that is, it
was a low area. As a result, the pit was often filled with water after rainfalls, and came to
be referred to as a pond. Because it was often the focal point for runoff from the Mill’s
ore pad and process facilities, it may also have accumulated any runoff from surface
spills of re-agents or process streams that could potentially have occurred during the
history of Mill operations. For example, any potential upsets in the nearby vanadium
circuit (which could contain nitrates, as discussed below) that may have resulted in spills
to the surface could have potentially impacted the Fly Ash Pond.

The Fly Ash pond was emptied out and the deposited fly ash was disposed of in Cell 2 in
1989. The emptied pit was filled with random fill and use of the pit ceased at that time.
However, because the area where the Fly Ash Pond had been located is at a relatively low
point, it has until recently continued to pool rainwater and has frequently been covered in
standing water during storms, overflowing onto the surrounding surface. This area was
re-graded and re-contoured in 2007 in an effort to better direct the runoff water to tailings
Cell 1 and to thereby minimize this pooling.

As discussed in Section 2, above, coal and coal-based combustion ash may exhibit up to
percent levels (tens of thousands of ppm) of bound or oxidized nitrogen. As also
15
mentioned, oxidized, distilled, and treated coal residuals were the chemical industry’s
most important source of nitrogen chemicals before the advent of high pressure synthesis
technology. The Fly Ash Pond could therefore be considered to be a potential source for
nitrate contamination in groundwater at the site. However, because the Fly Ash Pond is
located several hundred feet downgradient of TW4-25 and the upgradient boundary of the
plume, the Fly Ash Pond is not likely the most significant contributing source to the
plume.

Potential Spills from Uranium and Vanadium Circuit Chemicals

The Mill uses ammonia or amine compounds at several points in the processing circuits.
A summary of nitrogen-bearing compounds used in the Mill’s processes, from the
Operations Chemical Inventory in the Mill’s SPCC Plan is provided in Table 3a.

Anhydrous ammonia is stored as a gas in the tank farm before it is volatilized in a
vaporizer for 1) introduction to the yellowcake precipitation area and 2) pH adjustment in
the vanadium circuit. In these circuits, ammonia is dissolved into aqueous process
streams as ammonium hydroxide.

Ammonium sulfate, purchased and stored both as powdered solid and aqueous solution,
is added to the vanadium precipitation circuit. An organic amine, purchased and stored
as a liquid, is added to the solvent extraction (SX) circuit; however it is present in only
trace amounts in both the SX and counter-current decantation (CCD) areas.

Spills and overflows of these materials within the process buildings enter the floor drains
and are transferred to the tailings system. The process circuits and floor drains and
sumps that could historically have held or carried these solutions are designated on
Figure 3.

Based on information from Mill personnel, there has been no history of failures or upsets
of the storage tanks, drums, or powder containers of the liquid or solid materials in the
tank farm or in transfer to the Mill buildings. Although some of these materials contain
high concentrations of fixed or bound nitrogen, spills of these materials are too finite a
phenomenon to account for an ongoing plume on their own.

There is no history of spills or upsets of the anhydrous ammonia tank system. If an upset
were to occur in this system it would, in any case, generate primarily a gaseous emission,
not a liquid or solid discharge to the tank farm pads and berms.

The only potential ongoing source within the current Mill operations is theoretically the
vanadium and/or uranium circuit floor drain systems. Within the process buildings,
spills, overflows, wash-downs and other process waters containing ammonium hydroxide
(generated from the anhydrous ammonia), ammonium sulfate, and organic amine enter
the floor drain system from time to time and are transferred by above-ground pipe to the
tailings system. The floor drains are typical concrete box channels with top gratings,
designed to receive, collect, and channel spills, vessel overflows and drain-outs, and
16
wash-down waters to the tailings transfer lines. The types of activities that transfer
nitrogen-bearing solutions to the floor drains are ongoing and can be relatively frequent
during operational periods.

At the current time, there is no reason to expect that there are breaches or breaks in the
floor drains or the tailings transfer lines. As a result, the floor drains and transfer system
are an unconfirmed potential source.

However, for the foregoing reasons, and because all of the process circuits, floor drains
and sumps are located downgradient of TW4-25 and the upgradient boundary of the
plume, these should be considered to be low priority potential sources and hence given a
low priority in the Sample Plan.

Mill Laboratories

Table 3b lists nitrogen-bearing chemicals used and stored in small quantities in the Mill’s
on-site chemical and metallurgical laboratories. The laboratories stored and used small
(from 100ml vials to kilogram and liter quantities) of a variety of nitrogen-bearing
compounds as reagents, titrants, indicators, separating agents, and surfactants, for sample
preparation, extraction, and testing steps and received additional nitrogen-bearing process
samples from various points in the vanadium circuit for QC testing. Testing materials,
residuals, rinsates and other chemicals that reached the lab sinks and lab drain systems
were, as required by the Mill’s license conditions, discharged to the tailings system
commencing in June 1981, after completion of tailings Cell 1. Between around May
1980 and June 1981, laboratory wastes were discharged to the Former Office Leach
Field. Some nitrogen may therefore have been discharged to the Former Office Leach
Field prior to June 1981. In addition, potential leaks or breaches in the lab drain system
could also theoretically be a potential source of groundwater nitrogen, in part due to the
sheer number of different types of nitrogen compounds they may have transported.
However, the mass of nitrogen contained in the small volumes of bottled reagents and
process samples in the labs, even if their contents entered the drains in their entirety, are
likely too insignificantly small to account for the observed nitrate plume. Furthermore,
the Mill’s laboratory is located downgradient of TW4-25 and the upgradient boundary of
the nitrate plume. Therefore, the labs are a relatively low-priority source.

Tailings

The Mill’s tailings cells contain nitrogen in both the ammonia and nitrate forms. Mill
tailings solutions have been sampled from time to time over the Mill’s history. Care must
be taken in interpreting sample results, because the concentrations of analytes in tailings
solutions can vary significantly from one sample event to another, depending on:

• whether or not the Mill is operating,
• whether or not it is re-circulating tailings solutions into the process or adding
fresh water to the process, and
17
• the extent to which evaporation or rainfall have affected concentration or dilution
prior to sampling.

The Statement of Basis for the Mill’s GWDP reports that sample data from September
1980 through March 2003 showed a range for nitrite /nitrate in the Mill’s tailings
solutions of 17.0 mg/L to 49.2 mg/L, with an average of 30.91 mg/L. Recent sample
results obtained in August 2009 show concentrations of nitrite and nitrate in the solutions
in the slimes drain for Cell 2 of 38 mg/L that are consistent with these historic results.
The average concentrations for nitrite and nitrate in the pond solutions in Cells 1 and 3
were 254 mg/L and 102 mg/L, respectively, which are somewhat higher than those
historic numbers, possibly demonstrating the results of evaporation in those ponded areas
prior to sampling.

The presence of nitrate, as well as ammonia, in the Mill’s tailings is reasonable and
expected for the reasons discussed above, and summarized here:

• The Mill uses ammonia and amine nitrogen in several locations in the process
and re-circulates solutions of these materials to the tailings system – yielding
large masses and concentrations of ammonia nitrogen in tailings;
• The Mill introduced nitrate nitrogen, albeit for a finite period of two years,
into the uranium circuit and ultimately to the tailings system – yielding
smaller masses and concentrations of nitrate nitrogen in tailings; and
• Other sources of nitrogen (such as fly ash ) and surface runoff containing
nitrogen compounds, were exposed to atmospheric oxidizing conditions
before they were transferred to tailings – yielding smaller masses and
concentrations of nitrate nitrogen in tailings.

As a result, it is reasonable to expect and detect both a low level of nitrate and a higher
level of ammonia nitrogen in the tailings.

As discussed above, in biotic systems, ammonia nitrogen is readily converted to nitrite
and nitrate. In abiotic (non-living) systems, such as the tailings, this is not the case.
Ammonia nitrogen is soluble and stable in water in a non-living, non-oxidized system. It
remains in water in either ionized or unionized form, switching easily between the two,
depending on the pH of the solution. In aqueous systems with high pH, ammonia
remains in the non-ionized NH3 form. At neutral pHs and in low pH (acidic) systems
such as tailings, ammonia is present primarily in the ammonium ion form (NH4+). In the
abiotic, hot, acidic, low-oxygen, nutrient- and microbe-deficient environment of the
tailings solutions, ammonia nitrogen is not converted to nitrate (however, nitrate that
enters the system as nitrate remains as nitrate).

Like abiotic aqueous systems, groundwater also does not normally exhibit either the
aggressive chemical oxidizing or biologically enzyme-catalyzed conditions to convert
ammonia nitrogen into nitrite/nitrate. Hence, ammonia nitrogen that reaches groundwater
directly through failure of surface impoundment or structure liners, which has not been
exposed to atmospheric oxygen and bacteria before reaching groundwater, generally
18
would be expected to remain and be detected as ammonia or ammonia nitrogen, not
nitrate/nitrite, in groundwater.

In order for an ammonia nitrogen source to appear in groundwater as nitrate, it would
need to reach groundwater via a surface spill in which it would have time to be converted
to nitrate by chemical or biological processes before reaching groundwater.

Because the Mill’s tailings contain nitrate, the tailings cells are included here as a
potential source of nitrate in groundwater. However, given that:

• recent studies have indicated that the Mill’s tailings cells are not leaking ,
(including the July 2007 Hurst and Solomon Mill sampling event summary, the
INTERA Revised Background Groundwater Quality Report, November 2007
INTERA Revised Evaluation of Pre-Operational Background Data, and the April
2008 INTERA Revised Background Groundwater Quality Report).
• the nitrate plume has been detected in high concentrations in TW4-25, which is
almost a quarter of a mile upgradient of the Mill’s tailings cells;
• There appears to be no groundwater mounding under the tailings cells (see Figure
2 from the Stewart report),

it would appear that although the Mill’s tailings cells are a potential source of the nitrate
contamination, they are not a likely source of the contamination and should not be given
a high priority in the Sample Plan.

Other Surface Disposal Areas

During the Mill’s earlier history, the site contained a short-lived landfill for non-
contaminated Mill solid wastes. The landfill received non-hazardous debris and office
trash until it was shutdown in approximately 1982. All of the contents of that landfill
were excavated and disposed of in the solid waste disposal area of tailings Cell 2.

The location of this landfill is indicated on Figure 3.

While the landfill may have contained nitrogen-bearing compounds from food waste,
soap containers, and organic garbage, it would have been present at minutely low levels.
Unless chemical materials or sewage related solids were inadvertently placed there, it is
unlikely that the former landfill could pose an important source for the groundwater
nitrate plume, and should not be given a high priority in the Sample Plan.

Historic Pre-Mill Sources

Prior to construction of the Mill and related facilities, the Mill property was privately
owned and was used for cattle grazing. A barn and corral were located in the area close
to the current dike between Cell 1 and Cell 2, west of monitoring well TW4-24. Also, a
stock watering pond (the “Historic Pond”) was located northwest of the Mill’s
administration building, where the Mill’s sulfuric acid tank is currently located. There
19
was no irrigation or agriculture on the land. An aerial photo depicting the land use prior
to construction of Mill facilities is attached as Figure 5.

The Historic Pond was dammed and put in place many years prior to construction of the
Mill. In fact, it had the recognition of being the first dam built in Utah by a gas-powered
tractor, so it probably dates back to approximately the 1920s. The Historic Pond was
displaced by Mill facilities when the Mill was constructed. The main sulfuric acid tank at
the Mill is currently located on the site of the former Historic Pond. Many years of
livestock watering at the Historic Pond could have contributed significant amounts of
nitrate to the local soils and the pond. Pooled water in the pond could have provided a
sufficient head to drive this nitrate to groundwater. As the Historic Pond is a reasonable
source of nitrate over many years, and is located upgradient of the nitrate plume, it should
be given a priority in the Sample Plan.

It is also possible that the historic barn and corral could have been a source of nitrate at
the site. However, in the absence of standing water at that location, it is not likely that
such a source could have impacted groundwater. Also, the location of this potential
source is downgradient of the upgradient boundary of the current nitrate plume. For
these reasons, this potential historic source of nitrate should not be given a high priority
in the Sample Plan.

4.2 Offsite Sources

The Mill is located south of Blanding, Utah in a rural agricultural region of the state.
Land uses proximal to the Mill include farming, ranching, cattle grazing, feed and grain
silos, and the municipal wastewater treatment plant that serves Blanding and some of the
surrounding area. A substantial number of farms and ranches are likely not connected to
the municipal treatment facility and likely use septic systems for domestic sewage.
Direct fertilization with swine or cattle manure is also still practiced in rural Utah. The
town of Blanding, population 3,162 (2000 census), is approximately 5 miles north-
northeast of the Mill boundary.

One potential offsite source of nitrate is the management of livestock on properties
adjacent to the Mill’s restricted area, which are subject to cattle grazing leases. Such
cattle use the wildlife ponds for drinking water, and may have contributed nitrate to the
wildlife pond area. However, any addition of nitrate into the wildlife ponds from
livestock would be commingled with, and minimal compared to, the addition of nitrate
into the wildlife ponds from the Frog Pond waters. Therefore there is no need to perform
any additional investigations relating to livestock influences at the wildlife ponds. If the
wildlife ponds are determined to be the source of the nitrate plume, then it would be
reasonable to assume that the nitrate in the wildlife ponds could have originated from a
combination of the Frog Pond Water and these livestock activities.

It should be noted that nitrate in surface waters, estuarine, riparian, and humic surfaces is
a plant nutrient (hence the widespread use of nitrate fertilizers in agriculture). Nitrate in
these environments will be uptaken and converted by terrestrial and aquatic plants,
20
plankton, and algae in a cycle over time (nitrates are stable and non-volatile so they do
not vaporize directly to air from aqueous solutions). The total nitrate mass in such a
system is re-distributed among the sediments and precipitates, benthic materials, aquatic
plants and microorganisms, terrestrial plants and microorganisms, and macro-organisms
in the system in a cycle, whether the nitrate entered the system through aqueous transport
or soil deposition. Therefore the wildlife ponds could once have exhibited higher
concentrations of nitrate and been the source or contributor to a nitrate plume, even
though the current water in the wildlife ponds does not presently demonstrate high
concentrations of nitrate

Although this study did not include a rigorous itemization of all regulatory-listed sites or
contamination sources upgradient and side gradient of the Mill, overall, there are many
potential past and ongoing agricultural and domestic sources that may also affect the
nitrogen balance in groundwater entering the Mill boundary. However, because
upgradient monitoring wells MW-1, MW-18, and MW-19 do not indicate high
concentrations of nitrate, it is unlikely that any of these offsite sources are a continuing
source of the nitrate contamination. While it is possible that agricultural practices on
neighboring properties that occurred at some time in the past (but which no longer occur)
could have contributed a slug of nitrate contamination to groundwater that has passed by
the upgradient monitoring wells and that now forms the nitrate plume at the site, this
would appear to be unlikely and should not be a high priority in the investigation.

5.0 Potential Sources of Groundwater Chloride

For the discussion in the following section, it should be noted that, like the nitrate plume,
the chloride plume appears to originate to the northwest end of the Mill property,
generally upgradient of the tailings area, the Mill process buildings, and the outdoor
chemical storage areas.

5.1 On-Site Sources at the Mill

Processing and Laboratories

As indicated in my evaluations of alternate feed characteristics, alternate feed materials
have never been an appreciable source of chloride compounds, never exhibiting more
than ppm levels in finite volumes of materials that have either been stored in closed
containers or have remained on the ore pad less than a few months before processing.
Based on this history, chloride introduction into the Mill groundwater was likely
independent of the alternate feed program.

Table 3c lists chloride-bearing chemicals used in the Mill operations. Sodium chloride is
stored as bulk salt and used in regeneration of ion exchange resins in the uranium
recovery circuit. Sodium chlorate is stored in two fiberglass tanks (17,700 gallons and
10,500 gallons) within a dike east of the solvent extraction building. Other inorganic
chlorine compounds including sodium perchlorate, sodium hypochlorite, calcium
hypochlorite, and hydrochloric acid are stored in the tank farm or storage dike areas for
21
use throughout the process. Smaller quantities of inorganic and chloro-organic
compounds such as Ajax, bowl cleaner, and PVC cements are stored and used in the Mill
building and shops.

Based on information from Mill personnel, there has been no history of failures or upsets
of the storage tanks, drums, or powder containers of the liquid or solid materials in the
tank farm or in transfer to the Mill buildings. Although the salt storage area contains a
large volume of sodium chloride, spills of this material is too finite a phenomenon to
account for an ongoing plume by itself, as are sodium chlorate spills from the tank dikes
outside the solvent extraction tank area.

There is no history of spills or upsets of the chlorine tank system. If an upset were to
occur in this system it would, in any case, generate primarily a gaseous emission, not a
liquid or solid discharge to the tank farm pads and berms.

The only potential ongoing source within the current Mill operations is theoretically the
vanadium and/or uranium circuit floor drain systems. As discussed above, the types of
activities that transfer chloride solutions to the floor drains are ongoing and can be
relatively frequent during operational periods, however, at the current time, there is no
reason to expect that there are breaches or breaks in the floor drains or the tailings
transfer lines. More importantly, all of the process circuits, floor drains and sumps are
located downgradient of TW4-25 and the upgradient boundary of the chloride and nitrate
plumes, and as a result, cannot be the primary source of the groundwater contamination.

Table 3d lists chloride-bearing chemicals used and stored in small quantities in the Mill’s
on-site chemical and metallurgical laboratories. The laboratories stored and used small
(from 100ml vials to kilogram and liter quantities) of ammonium chloride and chlorine-
containing color indicators. However, the mass of chlorides contained in the small
volumes of bottled reagents and process samples in the labs, even if their contents entered
the laboratory drains in their entirety, are likely too insignificantly small to account for
the observed chloride plume. Furthermore, the Mill’s laboratory is located downgradient
of TW4-25 and the upgradient boundary of the chloride plume. Therefore, the labs could
be considered only a relatively low-priority source.

While there exist a number of different nitrogen-bearing and chloride bearing chemicals
at the Mill, the only single compound containing both a nitrogen and chloride source is
ammonium chloride. Ammonium chloride is stored in reagent bottle quantities in the
laboratory, and has never been inventoried in bulk quantities anywhere on site. Its
presence in the laboratory and occasionally in the laboratory drain system is not sufficient
to explain ongoing and coincident plumes of nitrate and chloride.

Tailings

The single largest mass of chloride in the Mill is the tailings system. USDOE data for
mills operating in the Moab area on Colorado Plateau ores indicates that tailings cell
chlorides average 310 mg/L. Data on Cell 3 indicate chloride levels from 3,191 mg/L
22
(Titan Enviornmental studies 1994) to 30,600 mg/L (Hazen studies 2001). Nitrate
content was not analyzed during these studies. If a source the size of the 3 million gallon
Cell 3 impoundment were continuously leaking a solution of these levels of chlorides, it
could potentially produce or contribute to an appreciable chloride plume. However, the
Mill tailings system is not likely a primary source of chloride for two reasons. First, if the
tailings system were leaking at an appreciable rate, there would be a sizeable hydraulic
mound under the tailings cells and chloride would not be the only ion detected in a
measurable plume. That is, other tailings constituents would be detected as well. Second
the plumes in question originate in the northeast corner of the site, and the tailings system
is side-gradient, and down-gradient of the majority of the affected wells.

5.2 Off-site Sources

Table 2b provides a summary of industrial, commercial, agricultural and municipal
sources of chloride compounds from which potential candidate sources for the Mill
chloride can be elicited. Due to the large number of synthetically created chlorinated
species in modern use, the table summarizes and addresses classes of chemicals rather
than individual compounds. Potential sources proximal to the Mill site are discussed
below. The upper section of the table identifies those compounds and classes of
materials that could be expected to be present on the Mill site or in the vicinity of the
Mill. The lower section completes a broader survey of compounds and sources and
indicates why they are not, or are likely not, present at or proximal to the Mill.

Sewage Sources

As mentioned above, chloride is present in all domestic wastewater and all septic and
sewage treatment effluent. In fact, per the McQuillan study, the presence of chloride in
nitrate contaminated groundwater is a primary parameter indicating for groundwater
nitrate originating from sewage sources. In sewage-related groundwater contamination,
groundwater chloride generally increases with nitrate level. In groundwaters affected by
septic system effluents, the relationship may be linear, as indicated in the New Mexico
studies. In surface waters receiving municipal treated sewage effluent, the relationship
varies with both treatment plant factors and receiving water factors, but still increases
with nitrate level.

Sewage sources are the most likely explanation for the coincident chloride and nitrate
plumes for several reasons. As discussed above, the coincident plumes appear to
originate northwest and upgradient of the Mill’s tailings, processing and storage areas.
The major potential source upgradient of the Mill is the Blanding POTW effluent
discharge system that reaches the Frog Pond, the Upper Wildlife Pond, Lawzy Lake, and
the Lawzy Sump. As evidenced by anecdotal information specific to the plant, it has had
multiple upsets that could have discharged sludge-bearing liquids to the ditches and
ponds upgradient of the site. As indicated in the technical literature on sewage treatment
plants from its time period, it very likely discharged both high nitrate and high chloride
loaded waters even in non-upset conditions. As evidenced by Mill operating history,
23
these wastewaters were transported on-site to the Mill for use as makeup water for the
leach circuit into the early 1990’s.

Moreover, the POTW effluent was a continuous source at one time. Unlike the Mill
chemical inventories, which are stored in finite quantities and can reach the environment
primarily by finite spills, the POTW effluent continually “recharges” the pond and ditch
systems upgradient of the identified plumes. However, management practices at the
POTW may have changed, and nitrate and chloride concentrations in effluent may have
decreased over time. This could have resulted in a “sludge flow” effect in the vicinity of
the site.

Agricultural Sources

In rural, non-industrial environments, the uses of inorganic chloride salts outweigh
synthetic organic chloride chemicals. Primary uses include road and surface de-icing,
water softening, septic system odor control, salt licks, meat curing and preserving, and
disinfectants in dairies and slaughter areas. Recent data from the middle Rio Grande
Valley indicate that the highest ratios of chloride to nitrate are generated in plumes from
dairies (likely a combination of nitrogen from cattle wastes and chlorine from dairy
surface disinfection).

To a lesser degree, some organic chlorides are still applied in agricultural areas in the
form of pesticides, herbicides, and grain and legume silo fumigants

Per the pre-operational baseline information for the Mill site, the site was used as
ranchland prior to construction of the Mill. The exact nature of historic operations is
unclear, that is, it is not known whether the ranch supported dairy cattle or beef cattle,
fertilized and grew feed and fodder of any type, maintained deer and cattle salt licks,
drained slops from slaughtering, or cured slaughtered meat, as well as where on the site
each activity occurred, and when the activity ceased. Hence it is plausible, but cannot be
confirmed, that on site agricultural activities using chloride salts, or generating chloride
byproducts and nitrogen wastes occurred.

Industrial Sources

The Blanding area and southeastern Utah in general are notable for their lack of chemical
production and heavy chemical use industries. None of the industrial processes that use
chlorine or chlorinated compounds as reagents, solvents or intermediates are present on
or near the Mill area. The presence of synthetic chloro-chemical sources in the region
can be assumed to be limited to small quantities of cleaners and solvents in homes,
ranches and farms, dry cleaners, and machine maintenance shops. With the exception of
the agricultural uses described in the paragraphs above, these uses are likely either too
small or too remote to have an appreciable effect on Mill site groundwater.

6.0 Conclusions

Based on the foregoing information, it can be concluded that:

There are several reasonable potential sources for nitrates in Mill groundwater:

• The septic leach fields at the site;
• The municipal sewage plant discharge water used historically as Mill
water makeup;
• Livestock activities at the wildlife ponds;
• Livestock activities at the Historic Pond;
• The former Fly Ash Pond;
• Potential historic spills of ammonia-bearing process chemicals;
• Potential breach in the vanadium circuit floor drains or tailings transfer
lines; and
• A potential leak in the Mill’s tailings cells.

There are several plausible sources for chloride in Mill groundwater:

• The septic leach fields at the site;
• The municipal sewage plant discharge water used historically as Mill
water makeup;
• Potential historic spills of chloride-bearing process chemicals;
• A potential leak in the Mill’s tailings cells.
• Agricultural/ranching activities on the site prior to Mill operations.

To date, the nitrate and chloride plumes have been identified to extend upgradient of
TW4-25, and to the northeast boundary of the Mill property. Of the potential sources
listed above, the only ones that originate upgradient of TW4-25 are:

1. the waters from the Frog Pond, the Upper Wildlife Pond, Lawzy Lake and the
Lawzy Sump, including potential livestock activity near the wildlife ponds;
2. possible livestock activity near the Historic Pond; and
3. possible influences from septic leach fields at the site, in particular the SAG
Leach Field and the Main Leach Field.

The other on-site potential sources would not appear to be able to explain the nitrate and
chloride contamination in TW4-25 or further upgradient. In addition, contamination due
to spills would appear to be too small and infrequent to give rise to the identified plumes,
and there is no apparent reason to expect a breach in process facilities and drains that
would give rise to the plume. Based on the currently available process and historic
information, the most plausible source for apparently coincident chloride and nitrate
plumes would be a chlorinated sewage-based source north or northwest of the Mill.

NOTES
1. Chemicals are generally adressed in this table as classes of materials rather than individual compounds.
2. Many chlorinated compounds , while not synthesized or used regionally or at the Mill, are present at low levels in domestic products
in the Mill offices, kitchen areas, shops, and labs.
3. Compunds containing both nitrogen and chlorine are addressed in Table 2a.
4. Additional chemicals inventoried from 100 ml to kilogram/liter levels at the laboratories are identifed in Table 3d.

Groundwater Monitoring
Quality Assurance Plan (QAP)
1. INTRODUCTION
Date:4-16-09 Revision-4
Page 6 of43
This Groundwater Monitoring Quality Assurance Plan (the "Plan") details and describes all
sampling equipment, field methods, laboratOlY methods, qualifications of environmental
analytical laboratories, data validation, and sampling and other corrective actions necessary to
comply with UAC R317-6-6.3(I) and (L) at the White Mesa Uranium Mill (the "Mill"), as
required under paragraph LH.6 of State of Utah Groundwater Discharge Permit No.
UGW370004 (the "GWDP") for the Mill. This Procedure incorporates the applicable
provisions of the United States Environmental Protection Agency ("EP A") RCRA
Groundwater Monitoring Technical Enforcement Guidance Document (OSWER-9950.1,
September, 1986), as updated by EPA's RCRA Ground-Water Monitoring: Draft Technical
Guidance (November 1992).
Activities in an integrated program to generate quality data can be classified as management
(i.e., quality assurance or "QA") and as functional (i.e., quality control or "QC"). The
objective of this Plan is to ensure that monitoring data are generated at the Mill that meet the
requirements for precision, accuracy, completeness, representativeness and comparability
required for management purposes and to comply with the reporting requirements established
by applicable permits and regulations.
2. ORGANIZATION AND RESPONSIBILITIES
2.1. Functional Groups
This Plan specifies roles for a QA Manager as well as representatives of three different
functional groups: the data users; the data generators, and the data reviewers/approvers. The
roles and responsibilities ofthese representatives are described below.
2.2. Overall Responsibility For the QAlQC Program
The overall responsibility for ensuring that the QA/QC measures are properly employed is the
responsibility of the QA Manager. The QA Manager is typically not directly involved in the
data generation (i.e., sampling or analysis) activities. At the Mill, the QA Manager is the
Mill's Radiation Safety Officer ("RSO") or other qualified person designated by Denison
Mines (USA) Corp. ("DUSA") corporate management.
2.3. Data Requestors/Users
The generation of data that meets the objectives of this Plan is necessary for management to
make informed decisions relating to the operation of the Mill facility, and to comply with the
reporting requirements set out in the GWDP and other permits and applicable regulations.
Accordingly, the data requesters/users (the "Data Users") are therefore DUSA's corporate
MiU-Groundwater Discharge Permit
Groundwater Monitoring
Quality Assurance Plan (QAP)
Date:4-16-09 Revision-4
Page 7 of43
management and regulatory authorities through the implementation of such permits and
regulations. The data quality objectives ("DQOs") required for any groundwater sampling
event, such as acceptable minimum detection limits, are specified in this Plan.
2.4. Data Generators
The individuals who carry out the sampling and analysis activities at the request of the Data
Users are the data generators. For Mill activities, this involves sample collection, record
keeping and QA/QC activities conducted by one or more sampling and quality control/data
monitors (each a "Sampling and QC Monitor"). The Sampling and QC Monitors are
radiation and environmental technicians or other qualified Mill personnel as designated by
the QA Manager. The Sampling and QC Monitors perform all field sampling activities,
collect all field QC samples and perform all data recording and chain of custody activities in
accordance with this Plan. Data generation at the contract analytical laboratory (the
"Analytical Laboratory") utilized by the Mill to analyze the environmental samples is
performed by or under an employee or agent (the "Analysis Monitor") of the Analytical
Laboratory, in accordance with specific requirements of the Analytical Laboratory's own
QA/QC program.
The responsibilities of the data generators are as follows:
2.4.1. Sampling and QC Monitors
The Sampling and QC Monitors are responsible for field activities. These include:
a) Ensuring that samples are collected, preserved, and transported as specified in Plan;
b) Checking that all sample documentation (labels, field data worksheets, chain-of-
custody records, packing lists) is correct and transmitting that information, along
with the samples, to the Analytical Laboratory in accordance with this Plan;
c) Maintaining records of all samples, tracking those samples through subsequent
processing and analysis, and, ultimately, where applicable, appropriately disposing of
those samples at the conclusion of the program;
d) Preparing quality control samples for field sample collection during the sampling
event;
e) Preparing QC and sample data for review by the QA Manager; and
f) Preparing QC and sample data for reporting and entry into a computer data base,
where appropriate.

2.4.2. Analysis Monitor
Date:4-16-09 Revision-4
Page 8 of43
The Analysis Monitor is responsible for QA/QC activities at the Analytical Laboratory.
These include:
a) Training and qualifying personnel in specified Analytical Laboratory QC and
analytical procedures, prior to receiving samples;
b) Receiving samples from the field and verifying that incoming samples correspond to
the packing list or chain-of-custody sheet; and
c) Verifying that Analytical Laboratory QC and analytical procedures are being
followed as specified in this Plan, by the Analytical Laboratory's QA/QC program,
and in accordance with the requirements for maintaining National Environmental
Laboratory Accreditation Program ("NELAP") and/or National Voluntary Laboratory
Accreditation Program ("NA VLAP") certification.
2.4.3. Data ReviewerslApprovers
The QA Manager has broad authority to approve or disapprove project plans, specific
analyses and final reports. In general, the QA Manager is responsible for reviewing and
advising on all aspects of QA/QC, including:
a) Ensuring that the data produced by the data generators meet the specifications set out
in this Plan;
b) Making on-site evaluations and submitting audit samples to assist in reviewing
QA/QC procedures;
c) Determining (with the Sampling and QC Monitor and Analysis Monitor) appropriate
sampling equipment and sample containers, in accordance with this Plan, to
minimize contamination; and
d) Supervising all QA/QC measures to assure proper adherence to this Plan and
determining corrective measures to be taken when deviations from this Plan occur.
The QA Manager may delegate certain of these responsibilities to one or more Sampling and
QC Monitors or to other qualified Mill personnel.

2.5. Responsibilities Of Analytical Laboratory
Date:4-16-09 Revision-4
Page 9 of43
Unless otherwise specified by DUSA corporate management, all environmental analysis of
groundwater sampling required by the GWDP or by other applicable permits, will be
performed by a contract Analytical Laboratory.
The Analytical Laboratory is responsible for providing sample analyses for groundwater
monitoring and for reviewing all analytical data to assure that data are valid and of sufficient
quality. The Analytical Laboratory is also responsible for data validation in accordance with
the requirements for maintaining NELAP and/or NAVLAP certification.
In addition, to the extent not otherwise required to maintain NELAP and or NAVLAP
certification, the Analytical Laboratory must adhere to U. S. EPA Guideline SW-846 and, to
the extent consistent with NELAP and EPA practices, the applicable portions of NRC
Regulatory Guide 4.14.
The Analytical Laboratory will be chosen by DUSA and must satisfy the following criteria:
(1) experience in analyzing environmental samples with detail for precision and accuracy, (2)
experience with similar matrix analyses, (3) operation of a stringent internal quality assurance
program meeting NELAP and/or NA VLAP certification requirements and that satisfies the
criteria set out in Section 8 below, (4) ability to satisfy radionuc1ide requirements as
stipulated in the applicable portions of NRC Regulatory Guide 4.14, and (5) certified by the
State of Utah for and capable of performing the analytical methods set out in Table 1. The
analytical procedures used by the Analytical Laboratory will be in accordance with Utah
Administrative Code R317-6-6.3L.
3. QUALITY ASSURANCE OBJECTIVES FOR MEASUREMENT OF DATA
The objective of this Plan is to ensure that monitoring data are generated at the Mill that meet
the requirements for precision, accuracy, representativeness, completeness, and comparability
required for management purposes and to comply with the reporting requirements established
by applicable permits and regulations (the Field and Analytical QC samples described in
Sections 4.3 and 8.1 below are designed to ensure that these criteria are satisfied). Data
subject to QA/QC measures are deemed more reliable than data without any QA/QC
measures.
3.1. Precision
Precision is defined as the measure of variability that exists between individual sample
measurements of the same property under identical conditions. Precision is measured
through the analysis of samples containing identical concentrations of the parameters of
concern. For duplicate measurements, precision is expressed as the relative percent
difference ("RPD") of a data pair and will be calculated by the following equation:
Mill-Groundwater Discharge Permit
Groundwater Monitoring
Quality Assurance Plan (QAP)
RPD= [(A-B)/{(A+B)/2}] X 100
Date:4-16-09 Revision-4
Page 10 of43
Where A (original) and B (duplicate) are the reported concentration for field duplicate
samples analyses (or, in the case of analyses performed by the Analytical Laboratory, the
percent recoveries for matrix spike and matrix spike duplicate samples) (EPA S W -846,
Chapter 1, Section 5.0, page 28).
3.2. Accuracy
Accuracy is defined as a measure of bias in a system or as the degree of agreement between a
measured value and an accepted or measured value. The accuracy of laboratory analyses is
evaluated based on analyzing standards of known concentration both before and during
analysis. Accuracy will be evaluated by the following equation (EPA SW -846, Chapter 1,
Section 5.0, page 24):
Where:
% Recovery = (I A-B I /C) x 100
A = the concentration of analyte in a sample
B = the concentration of analyte in an un spiked sample
C = the concentration of spike added
3.3. Representativeness
Representativeness is defined as the degree to which a set of data accurately represents the
characteristics of a population, parameter, conditions at a sampling point, or an
environmental condition. Representativeness is controlled by performing all sampling in
compliance with this Plan.
3.4. Completeness
Completeness refers to the amount of valid data obtained from a measurement system in
reference to the amount that could be obtained under ideal conditions. Laboratory
completeness is a measure of the number of samples submitted for analysis compared to the
number of analyses found acceptable after review of the analytical data. Completeness will
be calculated by the following equation:
Completeness = (Number of valid data points/total number of measurements) x 100
Mill -Groundwater Discharge Permit
Groundwater Monitoring
Quality Assurance Plan (QAP)
Date:4-16-09 Revision-4
Page II of 43
Where the number of valid data points is the total number of valid analytical measurements
based on the precision, accuracy, and holding time evaluation. Completeness is detennined
at the conclusion of the data validation.
Executive Secretary approval will be required for any completeness less than 100 percent.
3.5. Comparability
Comparability refers to the confidence with which one set of data can be compared to another
measuring the same property. Data are comparable if sampling conditions, collection
techniques, measurement procedures, methods, and reporting units are consistent for all
samples within a sample set.
4. FIELD SAMPLING QUALITY ASSURANCE METHODOLOGY
4.1. Controlling Well Contamination
Well contamination from external surface factors, is controlled by installation of a cap over
the surface casing and cementing the surface section of the drill hole. Wells have surface
covers of mild steel with a lockable cap cover. Radiation Safety staff has access to the keys
locking the wells.
Subsurface well stagnation, for pumped wells, is reduced by pumping two well casing
volumes of water from the wells, to the extent practicable. This ensures, to the extent
practicable, that the aquifer zone water is being drawn into the well and is a representative
sample.
4.2. Controlling Depth to Groundwater Measurements
Monitoring of depth to groundwater is controlled by comparing historical field log data to
actual measurement depth. This serves as a check of the field measurements.
4.3. Water Quality QC Samples
Quality assurance for ground water monitoring consists of the following QC samples:
4.3.1. VOC Trip Blanks
Trip blanks will be used to assess contamination introduced into the sample containers by
volatile organic compounds ("VOCs") through diffusion during sample transport and storage.
At a minimum (at least) one trip blank will be in each shipping container containing samples
to be analyzed for VOCs. Trip blanks will be prepared by the Analytical Laboratory,
transported to the sampling site, and then returned to the Analytical LaboratOlY for analysis
Mill -Groundwater Discharge Pennit
Groundwater Monitoring
Quality Assurance Plan (QAP)
Date: 4-16-09 Revision-4
Page 12 of43
along with the samples collected during the sampling event. The trip blank will be unopened
throughout the transportation and storage processes and will accompany the technician while
sampling in the field (DTG, Field and Laboratory Quality Assurance/Quality control, 7.8,
pages 7-30, 7-31)
4.3.2. Equipment Rinsate Samples
Where a portable (non-dedicated) pump is used, a rinsate sample will be collected prior to
using and after decontaminating the sampling equipment at the beginning of each sampling
event and at the beginning of each day of the sampling event (TEGD) Field QA/QC Program,
page 119). Where a non-dedicated bailer is used a rinsate sample will be collected prior to
any well sampling or purging and after decontamination at the beginning of each sampling
event and at the beginning of each day of the sampling event. In the case of equipment
rinsate blank samples for a pump, the sample will be prepared by pumping de-ionized water
into the sample containers. In the case of equipment rinsate blank samples for a non-
disposable or non-dedicated bailer, the sample will be prepared by pouring de-ionized water
over and through the bailer and into the sample containers. . During quarterly/semi-annual
monitoring events, equipment rinsate blanks will need to be analyzed only for the
contaminants required during the accelerated monitoring event.
4.3.3. Field Duplicates
One Duplicate set of samples submitted with each Batch (defined in Section 4.3.4) of
samples (DTG, Field and Laboratory Quality Assurance/Quality Control, 7.8), taken from
one of the wells being sampled and will be submitted to the Analytical Laboratory and
analyzed for all contaminants listed in Table 2 of the GWDP (EPA SW-846, Chapter 1,
Section 3.4.1).
4.3.4. Definition of "Batch"
For the purposes of this Plan, a Batch is defined as 20 or fewer samples (PA SW-846, Chapter 1,
Section 5.0, page 23).
5. CALIBRATION
A fundamental requirement for collection of valid data is the proper calibration of all sample
collection and analytical instruments. Sampling equipment shall be calibrated in accordance
with manufacturers' recommendations, and Analytical Laboratory equipment shall be
calibrated in accordance with Analytical Laboratory procedures.

5.1. Depth to Groundwater Measurements
Date:4-16-09 Revision-4
Page 13 of43
Equipment used in depth to groundwater measurements will be checked prior to each use to
ensure that the Water Sounding Device is functional.
5.2. Water Quality
The Field Parameter Meter will be calibrated prior to each sampling event and at the
beginning of each day of the sampling event according to manufacturer's specifications (for
example, by using two known pH solutions and one specific conductance standard.)
Temperature will be checked comparatively by using a thermometer. Calibration results will
be recorded on the Field Data Worksheet.
6. GROUND WATER SAMPLING AND MEASUREMENT OF FIELD

e) In any other wells or piezometers required by the Executive Secretary of the Utah
Radiation Control Board, as indicated by the Mill's RSO.
6.1.2. Equipment Used For Groundwater Head Monitoring
Measurement of depth to groundwater is accomplished by using a Solinist -IT 300 or
equivalent device (the "Water Sounding Device").
6.1.3. Field Sampling Procedure for Groundwater Head Monitoring
In the case of any well that is being sampled for groundwater quality, depth to groundwater is
measured prior to sampling.
Depth to groundwater is measured from the top of the inner well casing, or for the
piezometers, from the top of the casing, and is recorded on the Field Data Worksheet for
Groundwater described in Section 7.1 (the "Field Data Worksheet"). Readings are taken by
lowering the Water Sounding Device into the casing until the Device alarms, indicating that
the water surface has been reached. The depth to groundwater is then determined by
reference to the distance markings on the line attached to the Device. Data is recorded on the
Field Data Worksheet as Depth to Water, to the nearest 0.01 of a foot.
6.2. Ground Water Compliance Monitoring
6.2.1. Location and Frequency of Groundwater Compliance Monitoring
Groundwater quality shall be measured in the following wells at the following frequencies:
a) Semi-annually in the following Point of Compliance wells: MW-l, MW-2, MW-
3, MW-5, MW-12, MW-15, MW-17, MW-18 and MW-19;
b) Quarterly in the following Point of Compliance wells: MW -11, MW -14, MW -20,
MW-22, MW-26 and MW-32; and
c) Quarterly in the following new Point of Compliance wells, until 8 quarters of
background data are obtained: MW-23, MW-24, MW-25, MW-27, MW-28,
MW-29, MW-30 and MW-31. Thereafter, these wells will be sampled on a
quarterly or semi-annual basis, as required by the GWDP.

d) Chlorofonn Investigation sampling will collected from the locations and at the
frequencies listed at Item 2) in the Chloroform Investigation Monitoring Quality
Assurance Program (Appendix A to this document)
In addition, quarterly or monthly sampling may be required for certain parameters in certain
wells for which accelerated monitoring is required under paragraph I.G.I or I.G.2 of the
GWDP. It is important to confinn with the Mill's RSO prior to conducting any monitoring
well sampling, whether or not any parameters in any wells are subject to this accelerated

Mill -Groundwater Discharge Permit
Groundwater Monitoring
Quality Assurance Plan (QAP)
d) rinse the Sampling Equipment with de-ionized water.
Date:4-16-09 Revision-4
Page 18 of43
The probe should then be placed in the decontaminated probe sheath, or otherwise protected
from contamination until used for purging or sampling.
All water produced during decontamination will be containerized. Containerized water will
be disposed of in Tailings Cell 1.
All sampling and purging equipment that has been decontaminated as per the foregoing
procedure shall be covered with a plastic sheet to shield such equipment from dust or other
materials that may contaminate the equipment when traveling to and between
purging/sampling locations.
6.2.6. Pre-Purging/Sampling Activities
a) If a portable (non-dedicated) pump is to be used, prior to commencing the event's
sampling activities, check the pumping equipment to ensure that no air is leaking
into the discharge line, in order to prevent aeration of the sample;
b) If a portable (non-dedicated) pump is to be used, prior to each sampling event and at
the beginning of each day during the sampling event, decontaminate the sampling
pump using the procedure set forth in Section 6.2.5;
c) If a portable (non-dedicated) pump is to be used, after completion of
decontamination and prior to the beginning of each day of each sampling event,
prepare one Equipment Rinsate Sample by following the procedure set forth in
Section 4.3.2; and
d) Prior to leaving the Mill office, place the Trip Blank(s) into a cooler that will
preserve the VOC samples. The Trip Blank(s) will accompany the groundwater
samplers throughout the monitoring event.
6.2.7. Well Purging/Measurement of Field Parameters
a) Remove the well casing cap and measure and record depth to groundwater by
following the procedures set out in paragraph 6.1.3 above;
b) Determine the casing volume (V) in gallons, where h is column height of the water
in the well (calculated by subtracting the depth to groundwater in the well fi:om the
total depth of the well), V= O.653*h, for a 4" casing volume and V = .367*h for a 3"
casing volume. Record the casing volume on the Field Data Worksheet;
c) If the RSO has advised the field technician that immiscible contaminants (i.e.,
LNAPLs or DNAPLs) are known to occur or could potentially occur in the
Mill-Groundwater Discharge Pennit
Groundwater Monitoring

Date:4-l6-09 Revision-4
Page 19 of43
subsurface at the location of the well, follow the additional procedures, to be
provided by the RSO, prior to well purging;
d) Purging, Where Use of Pump is Effective (See paragraph 6.2.7 e)) below, where
bailer is required)
If a portable (non-dedicated) pump is used, ensure that it has been decontaminated in
accordance with Section 6.2.5 since its last use in a different well, lower the pump
into the well, making sure to keep the pump at least five feet from the bottom of the
well. Be sure never to drop the pump into the well, as this will cause degassing of the
water upon impact. Once the pump is lowered into the well, or if the well has a
dedicated pump, perform the following steps:
(i) Commence pumping;
(ii) Determine pump flow rate by using a stopwatch and a calibrated bucket by
measuring the number of seconds required to fill to the one-gallon mark.
Record this in the "pumping rate" section of the Field Data Worksheet;
(iii)Calculate the amount of time to evacuate two casing volumes;
(iv)Evacuate two casing volumes (if possible) by pumping for the length of time
determined in paragraph (iii);
(v) Take measurements of field parameters (pH, specific conductance,
temperature, redox potential and turbidity) during well purging, using the
Field Parameter Meter and turbidity measuring instrument. These
measurements will be recorded on the Field Data Worksheet. Purging is
completed after two casing volumes have been removed and the field
parameters pH, temperature, specific conductance, redox potential (Eh) and
turbidity have stabilized to within 10% over at least two consecutive
measurements. The groundwater in the well should recover to within at
least 90% of the measured groundwater static surface before sampling. In
addition, turbidity measurement in the water should be .:S 5 NTU prior to
sampling (DTG Well Development 6.7, page 6-48) unless the well is
characterized by water that has a higher turbidity. A flow-cell needs to be
used for field parameters. If the well is purged to dryness or is purged such
that full recovery exceeds two hours, the well should be sampled as soon as
a sufficient volume of groundwater is available to fill sample containers
(DTG, Well Purging, 7.2.4, page 7-9);
(vi) If the well yields two casing volumes, the individual performing the
sampling should immediately proceed to Section 6.2.8);
Mill-Groundwater Discharge Permit
Groundwater Monitoring
Quality Assurance Plan (QAP)
(vii) If the well cannot yield two casing volumes,
Date:4-16-09 Revision-4
Page 20 of43
A. Evacuate the well to dryness and record the number of gallons
evacuated on the Field Data Worksheet; and
B. Prior to sampling, measure and record depth to groundwater on the
Field Data Worksheet following the procedures set out in paragraph
6.1.3 above;
e) Purging, Where Use of Pump is Not Effective
For wells where a pump is not effective for purging and/or sampling (wells with
shallow water columns, i.e., where the water column is less than five feet above the
bottom of the well casing or the well takes over two days to recover from purging), a
disposable bailer, made of inert materials, may be used. If a bailer is used, the
following procedure will be followed:
(i) Use the sound level instrument to determine the water column and figure the
amount of water that must be evacuated;
(ii) Attach a 3" disposable bailer to a rope and reel;
(iii)Lower the bailer into the well and listen for contact with the solution. Once
contact is made, allow the bailer to gradually sink in the well, being careful
not to allow the bailer to come in contact with the bottom sediment;
(iv) After the bailer is full, retrieve the bailer and discharge the water from the
bailer into 5 gallon buckets. By doing this, one can record the number of
gallons purged;
(v)After the bailer is emptied, lower the bailer back into the well and gain another
sample as before. This process will continue until the two casing volumes
have been collected or until no more water can be retrieved. When the process
is finished for the well, the bailer will be disposed of; and
(vi)Take field measurements referred to in paragraph 6.2.7 (v) above from the
water in the buckets;

6.2.8. Samples to be taken and order a/taking samples
Date:4-16-09 Revision-4
Page 21 of43
For each sampling event, unless sampling for a specific parameter under the accelerated
monitoring requirements of paragraphs LG.1 or LG.2 of the GWDP as specified by the RSO,
the following separate samples shall be taken in the following order from each monitoring
well:
a) VOCs,3 sample containers, 40 ml each, (a bailer is used);
b) Nutrients (ammonia, nitrate and nitrite), 1 sample container, 100 ml (a bailer is
used);
c) Heavy metals, 1 sample container, 250 ml, filtered;
d) All other non-radiologics (fluoride, general inorganics, TDS, total cations and
anions), 1 sample container, 250 ml, filtered; and
e) Gross alpha, 1 sample container, 1,000 ml, filtered.
f) The sample collection containers and sample volumes for chloroform sampling are
specified at Item 3) of the Chloroform Investigation Monitoring Quality Assurance
Program (Appendix A to this document)
The number of sample containers and the quantities taken shall be as set out above, unless
otherwise dictated by the Analytical Laboratory, as specified by the RSO.
6.2.9. Field Duplicate Samples
a) One duplicate set of samples is required for each Batch of samples (see Section
4.3.4) for definition of Batch) (EPA SW-846, Chapter 1, Section 3.4.1). Field
duplicate samples will be analyzed for the contaminants listed in Table 2 of the
GWDP;
b) The duplicate samples should be as near to split samples as reasonably practicable,
rather than merely taking a second set of samples from the same well after the field
samples have been taken from that well. This can be accomplished by alternately
partially filling the field sample containers and duplicate containers until both sets of
containers are full.

Groundwater Monitoring
Quality Assurance Plan (QAP)
Date:4-16-09 Revision-4
Page 23 of43
(ii) Pump the sample through the filtration unit, and into the sample container at
the same rate or a lesser pumping rate than was used to purge the well;
(iii)The pump should be operated in a continuous manner so that it does not
produce samples that are aerated in the return tube or upon discharge;
(iv)Remove pump from the well; and
(v) If using a portable (non-dedicated pump), decontaminate pump as per Section
6.2.5. Do not place decontaminated pump on the ground or on other
contaminated surfaces;
d) When using a bailer to sample (wells with shallow water columns, i.e., where the
water column is less than five feet above the bottom of the well casing or the well
takes over two days to recover from purging), then one of the following two
procedures will be used:
(i) Filtering Water Samples at the Well Head
A. The sample water is collected by use of a 3 inch Teflon bailer, or the
equivalent, that is capable of being attached to a hand-operated
pressure pump, or the equivalent. Only disposable parts of the
pressure pump may come into contact with the sample water;
B. Attach the pump to the disposable bailer and activate the pump in
accordance with manufacturer's instructions, such that the sample
water in the bailer is forced through a clean, un-used, disposable 0.45
micron filter into a clean previously unused sample container, in a
manner such that only disposable parts of the pump mechanism come
into contact with the sample water;
C. Sample water should be transferred to sample containers in a
controlled manner that will minimize sample agitation and aeration;
D. Rinse lid of sample container with any remaining filtered water, after
container is filled with filtered water, and tighten lid onto container;
E. Unless dedicated to a particular well, dispose of the bailer, filter and
any parts of the pump mechanism that come into contact with the
sample water; and
F. No rinsate sample is needed, because everything that comes into
contact with the sample water is clean and unused prior to sampling,
and disposed of after sampling the well;
(ii) Filtering Water Samples at the Mill Laboratory
Mill -Groundwater Discharge Pennit
Groundwater Monitoring
Date:4-16-09 Revision-4
Quality Assurance Plan (QAP) Page 24 of43
A. A new, clean 1 gallon raw sample container must be used to capture
waters needed to be filtered;
B. The sample water is collected by use of a 3 inch Teflon bailer, or the
equivalent, and then discharged into the 1 gallon container;
c. After all the samples have been collected for the well and placed in the
field sample container, which contains blue ice to keep the samples at
the required temperature, the sampler will then proceed directly back
to the Mill laboratory and perform the filtration on the sample;
D. Unless the bailer is dedicated to a particular well, it will be disposed of
after completion of sampling in the well;
E. Upon arrival at the administration building, all other samples from the
well (that do not require filtration) will be placed in the sample holding
refrigerator in the locked sample storage room;
F. The sampler will then carry the sample that requires filtration in the
cooler to the laboratory and set up the equipment to be used for
filtration of the sample;
G. The equipment needed for this process consists of:
• 2000 ml glass filter flask
• 250 ml bell and glass frit for a micro-filtration 0.45 micron
filter setup
• 0.45 micron filter paper
H. The glass filter flask and micro-filtration equipment will go through a
cleaning and rinsate process. The processing will included the
following:
• Rinsing of the equipment using DI water
• Rinsing the equipment with a mixture ofDI water and HN03
• Rinsing the equipment with a mixture ofDI water and Liqui-
Nox soap
• Rinsing the equipment with DI water
• Finally the collection of the final process rinsate solutions are
placed in the sample collection cooler and labeled as a filtration
equipment rinsate sample;
1. The flask is attached to the vacuum system in the laboratOlY using
Tygon Vacuum Tubing, or the equivalent;
J. The micro-filtration system is then inserted into the filter flask;
K. A 0.45 micron filter paper is then placed between the bell and the glass
frit and clamped in place to prevent solution leaking out;
L. The water sample is then slowly added into the bell and the vacuum is
turned on;
M. As the vacuum draws the water through the filter paper, additional
solutions are added until the flask is full;
Mill -Groundwater Discharge Pennit
Groundwater Monitoring
Quality Assurance Plan (QAP)
Date:4-16-09 Revision-4
Page 25 of43
N. When the flask is full, the vacuum is turned off and the bell is
unclamped from the frit. The Tygon tubing is then removed from the
flask. The glass frit is then pulled out of the flask;
O. The filtered solutions are then poured into the various remaining
sample collection bottles. Sample water should be transferred to
sample containers in a controlled manner that will minimize sample
agitation and aeration;
P. Rinse lid of sample container with any remaining filtered water, after
container is filled with filtered water, and tighten lid onto container;
Q. If additional filtered water is required to complete the sample
requirements, the sample bottles will be placed in the field cooler
along with the raw sample and housed there while the filtration system
is being hooked back up and the procedures set out in paragraphs I to P
above are repeated until sufficient sample water has been filtered to fill
up the required number of sample bottles;
R. After all samples from the well that require filtration have been filtered
in accordance with the foregoing procedure and placed in the proper
sample bottles, the remainder of the raw sample is then discharged into
the laboratory sink, which runs to tails; and
S. The filtered samples are then transported to the locked sample storage
room and placed in the sample holding refrigerator.
The time lapse between the actual sampling times to the completion of the
filtration process is approximately 12 hour. Samples are always in the field
sample container, except for when the raw sample is pulled from the cooler
and poured in the bell on the filter flask.
6.2.12. Procedures to Follow After Sampling
a) In each case, once a sample is taken, identify and label the sample container with:
• Sample location/facility
• Date and time of sample
• Any preservation method utilized
• Sampler's initials
• Filtered or unfiltered
• Parameters requested to be analyzed
b) Place each sample in an ice-packed cooler, immediately upon taking the sample
and labeling the sample container;
c) Replace the casing cap on the well. Lock the well;

Page 28 of43
Original Certificates of Analysis from the Analytical Laboratory, showing the laboratory
analytical results for the water samples, are maintained at the Mill.
Once all the data for the quarter (all wells sampled during the quarter) is completed, key data
from the Field Data Worksheets and from the Certificates of Analysis are typed into a
computer file. Key data entered into the computer file will include well I.D., sample date,
depth to groundwater, average field data, and all laboratory analytical data. These computer
files are maintained at the Mill.
8. ANAL YTICAL PROCEDURES AND QA/QC
Analytical Laboratory QA provides a means for establishing consistency in the performance
of analytical procedures and assuring adherence to analytical methods utilized. Analytical
Laboratory QC programs include traceability of measurements to independent reference
materials and internal controls.
8.1. Analytical Quality Control
Analytical QA/QC will be governed by the QA/QC program of the Analytical Laboratory. In
choosing and retaining the Analytical Laboratory, DUSA shall ensure that the Analytical
Laboratory is certified by the State of Utah and by NELAP and/or NAVLAP, is capable of
performing the analytical procedures specified in Section 8.2, and that the QA/QC program
of the Analytical Laboratory includes the spikes, blanks and duplicates described in Section
8.1.2.
8.1.2. Spikes, Blanks and Duplicates
Analytical Laboratory QC samples will assess the accuracy and precision of the analyses.
The following describes the type of QC samples that will be used by the Analytical
Laboratory to assess the quality of the data. The following procedures shall be performed at
least once with each Batch of samples:
a) Duplicate Spike (Matrix Spike)
A split/spiked field sample shall be analyzed with every analytical batch. Analytes
stipulated by the analytical method, by applicable regulations, or by other specific
requirements must be spiked into the sample. Selection of the sample to be spiked
and/or split depends on the information required and the variety of conditions within a
Mill -Groundwater Discharge Pennit
Groundwater Monitoring
Quality Assurance Plan (QAP)
Date:4-16-09 Revision-4
Page 29 of43
typical matrix. The duplicate spike (matrix spike) sample serves as a check
evaluating the effect of the sample matrix on the accuracy of analysis.
b) Blanks
Each batch shall be accompanied by a reagent blank. The reagent blank shall be
carried through the entire analytical procedure. Contamination detected in analysis of
reagent blanks will be used to evaluate any Analytical Laboratory contamination of
environmental samples which may have occun-ed.
c) Field Samples/Sun-ogate Compounds
Every blank, standard, and environmental sample (including matrix spike/matrix
duplicate samples) shall be spiked with surrogate compounds prior to purging or
extraction. Sun-ogates are organic compounds which are similar to analytes of
interest in chemical composition, extraction, and chromatography, but which are not
normally found in environmental samples. Surrogates shall be spiked into samples
according to the appropriate organic analytical methods.
d) Check Sample
Each analytical batch shall contain a number of check samples. For each method, the
Analytical Laboratory will normally analyze the following check samples or their
equivalents: a method blank, a laboratory control spike, a matrix spike, and a matrix
spike duplicate, or the equivalent, with relative percent difference reported.
8.2. Analytical Laboratory Procedures
The analytical procedures to be used by the Analytical Laboratory will be as specified
in Table 1, or as otherwise authorized by the Executive Secretary. With respect to
Chloroform Investigation sampling, the analytical procedures for parameters
monitored under that program are specified at Item 4) of the ChlorofOlm Investigation

9. INTERNAL QUALITY CONTROL CHECKS
Internal quality control checks are inherent in this Plan. The QA Manager will monitor the
performance of the Sample and QC Monitors, and, to the extent practicable, the Analysis
Monitor to ensure that they are following this Plan. In addition, either the QA Manager or a
Sampling and QC Monitor will review and validate the analytical data generated by the
Analytical Laboratory to ensure that it meets the DQOs established by this Plant. Finally,
periodic system and performance audits will be performed, as detailed in Section 12 below.
9.1. Field QC Check Procedures
The QA Manager will perform the following QA/QC analysis of field procedures:
9.1.1. Review of Compliance With the Procedures Contained in this Plan
Observation of technician performance is monitored by the QA Manager on a periodic basis
to ensure compliance with this Plan.
9.1.2. Analyte Completeness Review
The QA Manager will review all Analytical Results to confirm that the analytical results are
complete (i.e., there is an analytical result for each required constituent in each well). The
QA Manager shall also identify and report all instances of non-compliance and non-
conformance (see Part I.E. 1. (a) of the Permit. Executive Secretary approval will be required
for any completeness (prior to QA/QC analysis) less than 100 percent. Non-confonnance
will be defined as a failure to provide field parameter results and analytical results for each
parameter and for each well required in Sections 6.2.2 and 6.2.3, for the sampling event,
without prior written Executive Secretary approval.
9.1.3. Blank Comparisons
Trip blanks, and equipment rinsate samples will be compared with original sample results.
Non-conformance conditions will exist when contaminant levels in the blank(s)/samples(s)
are within an order of magnitude of the original sample result. (TEGD, Field QA/QC
Program, page 119).
9.1.4. Duplicate Sample Comparisons
The following analyses will be performed on duplicate field samples:
Mill -Groundwater Discharge Pelmit
Groundwater Monitoring
Quality Assurance Plan (QAP)
a) Relative Percent Difference.
Date:4-16-09 Revision--4
Page 33 of43
RPDs will be calculated in comparisons of duplicate and original field sample results.
Non-conformance will exist when the RPD ~20%, unless the measured activities are less
than 5 times the required detection limit (Standard Methods, 1998) (EPA Contract
Laboratory Program National Functional Guidelines for Inorganic Data Review, February
1994,9240.1-05-01, p. 25).
b) Radiologies Counting Enor Term
All gross alpha analyses shall be reported with an error term. All gross alpha analysis
reported with an activity equal to or greater than the GWCL, shall have a counting
variance that is equal to or less that 20% of trhe reported activity concentration. An error
term may be greater than 20% of the reported activity concentration when the sum of the
activity concentration and enol' telm is less than or equal to the GWCL.
c) Radiologies, Duplicate Samples
Comparability of results between the original and duplicate radiologic samples will be
evaluated by determining compliance with the following formula:
Where:
A = the first duplicate measurement
B = the second duplicate measurement
sa2 = the uncertainty of the first measurement squared
sb2 = the uncertainty of the second measurement squared
Non-conformance exists when the foregoing equation is 2: 2.
(EP A Manual for the Certification of Laboratories Analyzing Drinking Water, Criteria and
Procedures Quality Assurance, January 2005, EPA 815-R-05-004, p. VI-9).
If the QA Managers review finds any situations of non-conformance, see Section 10.

Laboratory procedures are followed, (4) analytical results are correct and complete, (5) QC
samples are within established control limits, (6) blanks are within QC limits, (7) special
sample preparation and analytical requirements have been met, and (8) documentation is
complete.
The Analytical Laboratory will prepare and retain full QC and analytical documentation. The
Analytical Laboratory will report the data as a group of one batch or less, along with the
QA/QC data. The Analytical Laboratory will provide the following information: (1) cover
sheet listing samples included in report with a narrative, (2) results of compounds identified
and quantified, and (3) reporting limits for all analytes. Also to be included are the QA/QC
analytical results.
9.3. QA Manager Review of Analytical Laboratory Results and Procedures.
The QA Manager shall perform the following QA reviews relating to Analytical Laboratory
procedures:
a) Reporting Limit (RL) Comparisons
The QA Manager shall confirm that all reporting limits used by the Analytical Laboratory are
in conformance with the reporting limits set out on Table 1. Non-conformance shall be
defined as: 1) a reporting limit that violates these provisions, unless the reporting limit must
be increased due to sample matrix interference (i.e., due to dilution gain); or 2) a reporting
limit that exceeds the respective GWQS listed in Table 2 of the GWDP.
b) Laboratory Methods Review
The QA Manager shall con film that the analytical methods used by the Analytical Laboratory
are those specified in Table 1, unless otherwise approved by the Executive Secretary. Non-
confOlmance shall be defined when the Analytical Laboratory uses analytical methods not

9.4. Analytical Data
All QA/QC data and records required by the Analytical Laboratory's QA/QC program shall
be retained by the Analytical Laboratory and shall be made available to DUSA as requested.
Analytical data submitted by the Analytical Laboratory should contain the date/time the
sample was collected, the date/time the sample was received by the Analytical Laboratory,
the date/time the sample was extracted (if applicable), and the date/time the sample was
analyzed.
All out-of-compliance results will be logged by the Analysis Monitor with corrective actions
described as well as the results of the cOlTective actions taken. All raw and reduced data will
be stored according to the Analytical Laboratory's record keeping procedures and QA
program. All Analytical Laboratory procedures and records will be available for on-site
inspection at any time during the course of investigation.
lfre-runs occur with increasing frequency, the Analysis Monitor and the Mill's QA Manager
will be consulted to establish more appropriate analytical approaches for problem samples.
10. CORRECTIVE ACTION
10.1. When Corrective Action is Required
The Sampling and QC Monitors and Analytical Laboratory are responsible for following
procedures in accordance with this Plan. COlTective action should be taken for any procedure
deficiencies or deviations noted in this Plan. All deviations from field sampling procedures
will be noted on the Field Data Worksheets or other applicable records. Any QA/QC
problems that arise will be brought to the immediate attention of the QA Manager.

Page 38 of43
In addition, an electronic copy of all analytical results will be transmitted to the Executive
SecretalY in comma separated values (CSV) format, or as otherwise advised by the Executive
Secretary.
Further reporting may be required as a result of accelerated monitoring under paragraphs
LG.l and LG.2 of the GWDP. The frequency and content of these reports will be defined by
DUSA corporate management working with the Executive Secretary.
12. SYSTEM AND PERFORMANCE AUDITS
12.1. QA Manager to Perform System Audits and Performance Audits
DUSA shall perform such system audits and perfOlmance audits as it considers necessary in
order to ensure that data of known and defensible quality are produced during a sampling
program. The frequency and timing of system and performance audits shall be as determined
by DUSA.
12.2. System Audits
System audits are qualitative evaluations of all components of field and Analytical
Laboratory QC measurement systems. They determine if the measurement systems are being
used appropriately. System audits will review field and Analytical Laboratory operations,
including sampling equipment, laboratory equipment, sampling procedures, and equipment
calibrations, to evaluate the effectiveness of the QA program and to identify any weakness
that may exist. The audits may be calTied out before all systems are operational, during the
program, or after the completion of the program. Such audits typically involve a comparison
of the activities required under this Plan with those actually scheduled or performed. A
special type of systems audit is the data management audit. This audit addresses only data
collection and management activities.
12.3. Performance Audits
The perfOlmance audit is a quantitative evaluation of the measurement systems of a program.
It requires testing the measurement systems with samples of known composition or behavior
to evaluate precision and accuracy. With respect to performance audits of the analytical
process, either blind performance evaluation samples will be submitted to the Analytical
Laboratory for analysis, or the auditor will request that it provide results of the blind studies
that the Analytical Laboratory must provide to its NELAP and/or NA VLAP accreditation
agency on an annual basis. The performance audit is carried out without the knowledge of
the analysts, to the extent practicable.
Mill -Groundwater Discharge Petmit
Groundwater Monitoring
Date:4-16-09 Revision-4
Quality Assurance Plan (QAP) Page 39 of43
12.4. Follow-Up Actions
Response to the system audits and perfonnance audits is required when deviations are found
and corrective action is required. Where a corrective action is required, the steps set out in
Section 10.2 will be followed.
12.5. Audit Records
Audit records for all audits conducted will be retained in Mill Central Files. These records
will contain audit reports, written, records of completion for corrective actions, and any other
documents associated with the audits supporting audit findings or corrective actions.
13. PREVENTIVE MAINTENANCE
Preventive maintenance concerns the proper maintenance and care of field and laboratory
instruments. Preventive maintenance helps ensure that monitoring data generated will be of
sufficient quality to meet QA objectives. Both field and laboratory instruments have a set
maintenance schedule to ensure proper functioning of the instruments.
Field instruments will be maintained as per the manufacturer's specifications and established
sampling practice. Field instruments will be checked and calibrated prior to use, in
accordance with Section 5. Batteries will be charged and checked daily when these
instruments are in use. All equipment out of service will be immediately replaced. Field
instruments will be protected from adverse weather conditions during sampling activities.
Instruments will be stored properly at the end of each working day. Calibration and
maintenance problems encountered will be recorded in the Field Data Worksheets or
logbook.
The Analytical Laboratory is responsible for the maintenance and calibration of its
instruments in accordance with Analytical Laboratory procedures and as required in order to
maintain its NELAP and/or NAVLAP certifications. Preventive maintenance will be
perfonned on a scheduled basis to minimize downtime and the potential interruption of
analytical work.
14. QUALITY ASSURANCE REPORTS TO MANAGEMENT
14.1. Ongoing QA/QC Reporting
The following reporting activities shall be undertaken on a regular basis:
a) The Sample and QC Monitors shall report to the QA Manager regularly regarding
progress of the applicable sampling program. The Sample and QC Monitors will
Mill -Groundwater Discharge Pennit

Quality Assurance Plan (QAP) Page 40 of43
also brief the QA Manager on any QA/QC issues associated with such sampling
activities.
b) The Analytical Laboratory shall maintain detailed procedures for laboratory record
keeping. Each data set report submitted to the Mill's QA Manager or his staff will
identify the analytical methods performed and all QA/QC measures not within the
established control limits. Any QA/QC problems will be brought to the QA
Manager's attention as soon as possible; and
c) After sampling has been completed and final analyses are completed and reviewed, a
brief data evaluation summary report will be prepared by the Analytical Laboratory
for review by the QA Manager, by a Sampling and QC Monitor or by such other
qualified person as may be designated by the QA Manager. The report will be
prepared in accordance with NELAP and/or NAVLAP requirements and will
summarize the data validation efforts and provide an evaluation of the data quality.
14.2. Periodic Reporting to Management
The QA Manager shall present a report to DUSA's ALARA Committee at least once per
calendar year on the performance of the measurement system and the data quality. These
reports shall include:
a) Periodic assessment of measurement quality indicators, i.e., data accuracy, precision
and completeness;
b) Results of any perfOlmance audits, including any corrective actions;
c) Results of any system audits, including any corrective actions; and
d) Significant QA problems and recommended solutions.
15. AMENDMENT
This Plan may be amended from time to time by DUSA only with the approval of the
Executive Secretary.

This document sets out the quality assurance plan to be used by Denison Mines (USA)
Corp. for Chlorofonn Investigation conducted pursuant to State of Utah Notice of
Violation and Groundwater Corrective Action Order (UDEQ Docket No. UGW-20-01)
(the "Order).
Specifically, the mill will use the same sampling regimen for the Chlorofonn
Investigation that is utilized for groundwater sampling under its groundwater discharge
pennit, as set forth in the attached groundwater discharge pennit Quality Assurance Plan
(QAP), except as set forth below:
1) Dedicated Purge Pump
Chlorofonn Investigation samples are collected by means of dedicated bailer(s) that
remain inside the well casing (suspended and secured with a rope) or by means of a
disposable bailer used only for the collection of a sample only from an individual well
and disposed subsequent to the sampling. The wells are purged by means of a p0l1able
pump. Each quarterly pumping and sample collection event begins at the location least
affected by chlorofonn (based on the previous quarters sampling event) and proceeds by
affected concentration to the most affected location. -. Decontamination of All sampling
equipment will follow the decontamination procedure outlined in section 6.2.5 of the
QAP.
2) ChlorofOlID Investigation Sampling Frequency, Order and Locations
The chlorofonn investigation wells listed below are required to be monitored on a
quarterly basis under State of Utah Notice of Violation and Groundwater Corrective
Action Order UDEQ Docket No. UGQ-20-01. ChlorofOlID wells shall be collected from
the least contaminated to the most contaminated as based on the most recent quarterly
results.

The chloroform investigation sampling program requires a specific number of
sampling containers and the collection of specific volumes of sample.
Accordingly, the following sample volumes are collected by bailer from each
sampling location:
• For Volatile Organic Compounds (VOC), collect three samples into three
separate 40 ml containers.
• For NitratelNitrite determinations, collect one sample into a 100 ml
container.
• For inorganic Chloride, collect one sample into a 100 ml container.
4) Laboratory Requirements
Collected samples which are gathered for chloroform investigation purposes are
delivered to an outside laboratory where the requisite analyses are performed. At
the laboratory the following analytical specifications must be adhered to:

Attachment 4
Initial Nitrate Monitoring Report

laboratory analysis and quality assurance documentation under Tab F of this report, and the Field
Data Worksheets for those samplings are provided at Tab B.

Regularly scheduled sampling of compliance monitoring wells under the Mill’s State of Utah
Groundwater Discharge Permit No UGW370004 (the “GWDP”) and under the chloroform
investigation for nitrate and chloride are reported in the applicable quarterly groundwater
monitoring reports for those sampling events.

2.1.3 Constituents Monitored

Wells sampled as an element of the Nitrate Investigation were analyzed for the following
constituents:

 Nitrogen, Nitrate + Nitrite as N
 Chloride

2.1.4 Groundwater Head Monitoring

Depth to groundwater measurements were taken in the following wells and/or piezometers at the
time of sample collection for the purposes of the Nitrate Investigation:

a) All nitrate contaminant investigation wells listed in paragraph 2.1.1 above;
and
b) Site Piezometers – P-1, P-2, P-3, P4, and P5 (Routine GWDP 12-11-09)

2.2. Sampling Methodology, Equipment and Decontamination Procedures

The sampling methodology, equipment and decontamination that were applied to the nitrate
contaminant investigation can be summarized as follows:

2.2.1 Well Purging and Depth to Groundwater

a) A list was prepared of the wells in order of increasing nitrate contamination.
The order for purging was established in accordance with this listing. Mill personnel
started purging with the lowest concentration well (as initially determined by nitrate
field test strips and later by means of laboratory results as the Investigation proceeded)
and then moved to the more contaminated wells in order of nitrate contamination; and

With respect to sampling that was done prior to October 29, 2009, before leaving the Mill office,
the pump and hose were decontaminated utilizing the cleaning agents described in Section 6.2.5
of the White Mesa Mill Groundwater Monitoring Quality Assurance Plan (QAP) (the “QAP”).
Mill personnel then proceeded to the first well, that being the well indicating the lowest
concentration of nitrate either at the time of well construction or by means of further laboratory
analyses as the project proceeded. Well depth measurements were taken and the two casing
volumes were calculated (measurements were made using the same.

3.1 Analytical Results

3.2.1 Copy of Laboratory Results

Included under Tab F of this Report are copies of all laboratory analytical results for the
groundwater quality samples collected in 2009 during the Nitrate Investigation.

3.2.2 Electronic Data Files and Format (Tab G)

DUSA is providing the Executive Secretary an electronic copy of all laboratory results for
groundwater quality monitoring conducted under the Nitrate Investigation, in Comma Separated
Values (CSV). These transmissions will be sent via email on or before January 4, 2010.

3.2.3 Current Nitrate Isoconcentration Map

Included under Tab C of this Report are current nitrate and chloride isoconcentration maps for
the Mill site.

3.2.4 Data and Graphs Showing Nitrate and Chloride Concentration

Attached under Tab H is a table summarizing nitrate and chloride values reported in 2009 for
each sampling point under investigation.

Attached under Tab I are graphs showing nitrate and chloride concentration trends in each
sampling point during 2009

3.3. Quality Assurance Evaluation And Data Validation

Quality assurance evaluation and data validation procedures described in the Mill’s Quality
Assurance Program for Groundwater Monitoring (QAP) were in effect at the time of sampling
events and were deemed applicable to the Nitrate Investigation. These procedures involve three
basic types of evaluations: Field QC checks; Analytical Laboratory checks; and checks
performed by DUSA personnel, as described below.

3.3.1 Field QC Checks

Field Quality Control samples for the Nitrate Investigation consisted of a field duplicate samples,
DI blank samples and equipment rinsate samples. The results of these analyses are included with
the routine analyses under Tab F.

3.3.2 Analytical Laboratory QA/QC Procedures

The Analytical Laboratory has provided summary reports of the analytical quality
assurance/quality control (QA/QC) measurements necessary to maintain conformance
12

The QA Manager reviewed the Analytical Laboratory’s QA/QC Summary Reports and made the
following conclusions;

i. Check samples were analyzed for each method used in analyzing the
Nitrate investigation samples. These methods were:

Parameter Method

Nitrogen, (Nitrate + Nitrite as N)E353.2

Chloride A4500-CL B and E300.0

ii. The check samples included at least the following: a method blank, a
laboratory control spike (sample), a matrix spike and a matrix spike duplicate;

iii. All qualifiers, if any and the corresponding explanations in the
summary reports are reviewed by the QA Manager. The only qualifiers reported
were for matrix interference in some of the analyzed monitoring location
samples. However, despite the increase in detection limit, sample results were
detected.

The laboratory holding time for all analyses was within specification and sample temperature
was acceptable upon receipt.

4.0 Corrective Actions

Based upon the review of sample procurement and the exceptions noted in Section 3.3.3.b)
above, sample collection activities require improvement. Accordingly, necessary corrective
actions in accordance with Section 10 of the QAP are as described below:

4.1 Identification and definition of the problem

The problems identified during the review of Field Data Worksheets included:

 Failure to decontaminate non-dedicated pumping equipment between
sampling locations during the February, July and August sampling events.
 Failure to evacuate 2 casing volumes during purging operations,
 Failure to measure at least 2 field parameter data sets within +/- 10%, and
 Failure to maintain turbidity below 5 NTU in collected samples.

Sample Delivery Group: C09070903
ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submitlals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Date: 03-Aug-09
CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS USING EPA 505
Data for Atrazine and Simazine are reported from EPA 525.2, not from EPA 505. Data reported by ELI using EPA method
505 reflects the results for seven individual Aroclors. When the results for all seven are NO (not detected), the sample
meets EPA compliance criteria for PCB monitoring .
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

Date: 04·Sep·09
CASE NARRATIVE
37/37
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable wa ters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE. SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB da ta reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected). the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the

Project: 4th Quarter Nitrate & Chloride CASE NARRATIVE
Sample Delivery Group: C09101104
ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been retumed with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (±2'C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after co llection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low lOS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recomme nded delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE. SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by Ell reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qu alified contract laboratori es for this service. Any such laboratories will be indicated within the

Sample Delivery Group: C091 10461
ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (±2'C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed B days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE. SIMAZINE AND PCB ANALYSIS
Data for PCBs. Atrazine and Simazine are reported from EPA 525.2. PCB data reported by Ell renects the results for seven
individual Aroclors. When the results for all seven are NO (not detected). the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so. ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the

ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been retumed with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (±2'C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low lOS waters. Data provided by
thi s method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recom mended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLI D SAMPLES
All samples reported on an as received basis unless otherwise indica ted.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Arodors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.

1. INTRODUCTION

This report provides a brief description of the hydrogeology of the White Mesa Uranium
Mill Site, located south of Blanding, Utah, and focuses on the occurrence and flow of
groundwater within the relatively shallow perched groundwater zone at the site. Based on
available existing hydrogeologic information from the site, estimates of hydraulic gradients and
intergranular rates of groundwater movement (interstitial or pore velocities) are provided. These
estimates are then used to calculate average pore velocities for a hypothetical conservative solute
(assuming no hydrodynamic dispersion) within 1) an area downgradient of the tailings cells, 2)
beneath and immediately upgradient and crossgradient of the tailings cells, and 3) within the
northeastern portion of the site.

The results of hydraulic testing of the TWN-series wells, located in the northeastern
portion of the site are provided in Appendix A and are used to calculate pore velocities in an area
affected by elevated nitrate concentrations. Figure 1 shows the locations of these and other
perched zone monitoring wells at the site.

2. SITE HYDROGEOLOGY

Titan, 1994 provides a detailed description of site hydrogeology based on information
available at that time. A brief summary of site hydrogeology that is based primarily on Titan,
1994, but includes the results of more recent site investigations, is provided below.

2.1 Geologic Setting

The White Mesa Uranium Mill site (the “Mill” or the “site”) is located within the
Blanding Basin of the Colorado Plateau physiographic province. Typical of large portions of the
Colorado Plateau province, the rocks underlying the site are relatively undeformed. The average
elevation of the site is approximately 5,600 feet above mean sea level (ft amsl).

The site is underlain by unconsolidated alluvium and indurated sedimentary rocks
consisting primarily of sandstone and shale. The indurated rocks are relatively flat lying with
dips generally less than 3º. The alluvial materials consist mostly of aeolian silts and fine-grained
aeolian sands with a thickness varying from a few feet to as much as 25 to 30 feet across the site.
The alluvium is underlain by the Dakota Sandstone and Burro Canyon Formation, which are
sandstones having a total thickness ranging from approximately 100 to 140 feet. Beneath the
Burro Canyon Formation lies the Morrison Formation, consisting, in descending order, of the
Brushy Basin Member, the Westwater Canyon Member, the Recapture Member, and the Salt
Wash Member. The Brushy Basin and Recapture Members of the Morrison Formation,
classified as shales, are very fine-grained and have a very low permeability. The Brushy Basin

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 4
Member is primarily composed of bentonitic mudstones, siltstones, and claystones. The
Westwater Canyon and Salt Wash Members also have a low average vertical permeability due to
the presence of interbedded shales.

Beneath the Morrison Formation lie the Summerville Formation, an argillaceous
sandstone with interbedded shales, and the Entrada Sandstone. Beneath the Entrada lies the
Navajo Sandstone. The Navajo and Entrada Sandstones constitute the primary aquifer in the
area of the site. The Entrada and Navajo Sandstones are separated from the Burro Canyon
Formation by approximately 1,000 to 1,100 feet of materials having a low average vertical
permeability. Groundwater within this system is under artesian pressure in the vicinity of the
site, is of generally good quality, and is used as a secondary source of water at the site.

2.2 Hydrogeologic Setting

The site is located within a region that has a dry to arid continental climate, with an
average annual precipitation of approximately 13.3 inches, and an average annual lake
evaporation rate of approximately 47.6 inches. Recharge to aquifers occurs primarily along the
mountain fronts (for example, the Henry, Abajo, and La Sal Mountains), and along the flanks of
folds such as Comb Ridge Monocline.

Although the water quality and productivity of the Navajo/Entrada aquifer are generally
good, the depth of the aquifer (approximately 1,200 feet below land surface [ft bls]) makes
access difficult. The Navajo/Entrada aquifer is capable of yielding significant quantities of water

to wells (hundreds of gallons per minute [gpm]). Water in wells completed across these units at
the site rises approximately 800 feet above the base of the overlying Summerville Formation.

Perched groundwater in the Dakota Sandstone and Burro Canyon Formation is used on a
limited basis to the north (upgradient) of the site because it is more easily accessible. Water
quality of the Dakota Sandstone and Burro Canyon Formation is generally poor due to high total
dissolved solids (TDS) and is used primarily for stock watering and irrigation. The saturated
thickness of the perched water zone generally increases to the north of the site, increasing the
yield of the perched zone to wells installed north of the site.

2.3 Perched Zone Hydrogeology

Perched groundwater beneath the site occurs primarily within the Burro Canyon
Formation. Perched groundwater at the site has a generally low quality due to high total
dissolved solids (TDS) in the range of approximately 1,100 to 7,900 milligrams per liter (mg/L),
and is used primarily for stock watering and irrigation in the areas upgradient (north) of the site.
Perched water is supported within the Burro Canyon Formation by the underlying, fine-grained
Brushy Basin Member. Figure 2 is a contour map showing the approximate elevation of the
contact of the Burro Canyon Formation with the Brushy Basin Member, which essentially forms
the base of the perched water zone at the site. Wells and piezometers shown in Figures 1 and 2
consist of surveyed perched zone monitoring wells and piezometers that include temporary
perched zone monitoring wells (TW4-and TWN-series wells). The TW4-series wells are
associated with an area of elevated perched zone chloroform concentrations located east and

December 29, 2009 6
northeast (cross-gradient to upgradient) of the tailings cells. The TWN-series wells are
associated with areas of elevated nitrate and chloride in the northeastern portion of the site,
upgradient of the tailings cells. Contact elevations between the Burro Canyon Formation and
Brushy Basin Member are based on perched monitoring well drilling and geophysical logs and
surveyed land surface elevations. As indicated, the Burro Canyon/Brushy Basin contact
(although irregular because it represents an erosional surface) generally dips to the
south/southwest beneath the site.

Figures 3 through 6 are perched groundwater elevation contour maps for the years 1990,
1994, 2002, and 2009, respectively. Based on the contoured water levels, groundwater within
the perched zone flows generally south to southwest beneath the site. Beneath the tailings cells,
perched groundwater flow is generally southwest to south-southwest. Perched groundwater flow
will be discussed in more detail in Section 2.3.2.

2.3.1 Lithologic and Hydraulic Properties

Although the Dakota Sandstone and Burro Canyon Formations are often described as a
single unit due to their similarity, previous investigators at the site have distinguished between
them. The Dakota Sandstone is a relatively-hard to hard, generally fine-to-medium grained
sandstone cemented by kaolinite clays. The Dakota Sandstone locally contains discontinuous
interbeds of siltstone, shale, and conglomeratic materials. Porosity is primarily intergranular.
The underlying Burro Canyon Formation hosts most of the perched groundwater at the site. The
Burro Canyon Formation is similar to the Dakota Sandstone but is generally more poorly sorted,

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 7
contains more conglomeratic materials, and becomes argillaceous near its contact with the
underlying Brushy Basin Member. The permeabilities of the Dakota Sandstone and Burro
Canyon Formation at the site are generally low.

No significant joints or fractures within the Dakota Sandstone or Burro Canyon
Formation have been documented in any wells or borings installed across the site (Knight
Piésold, 1998). Any fractures observed in cores collected from site borings are typically
cemented, showing no open space.

2.3.1.1 Dakota

Based on samples collected during installation of wells MW-16 (no longer used) and
MW-17, located immediately downgradient of the tailings cells, porosities of the Dakota
Sandstone range from 13.4% to 26%, averaging 20%, and water saturations range from 3.7% to
27.2%, averaging 13.5%. The average volumetric water content is approximately 3%. The
hydraulic conductivity of the Dakota Sandstone based on packer tests in borings installed at the
site ranges from approximately 2.7 x 10-6 centimeters per second (cm/s) to 9.1 x 10-4 cm/s, with a
geometric average of 3.9 x 10-5 cm/s.

2.3.1.2 Burro Canyon

The average porosity of the Burro Canyon Formation is similar to that of the Dakota
Sandstone. Based on samples collected from the Burro Canyon Formation at MW-16 (no longer

Site Hydrogeology & Est. GW Travel Times

used), located immediately downgradient of tailings cell #3, porosity ranges from 2% to 29.1%,
averaging 18.3%, and water saturations of unsaturated materials range from 0.6% to 77.2%,
averaging 23.4%. Titan, 1994, reported that the hydraulic conductivity of the Burro Canyon
Formation ranges from 1.9 x 10-7 to 1.6 x 10 -3 cm/s, with a geometric mean of 1.1 x 10-5 cm/s,
based on the results of 12 pumping/recovery tests performed in monitoring wells and 30 packer
tests performed in borings prior to 1994.

Hydraulic testing of wells MW-01, MW-03, MW-05, MW-17, MW-18, MW-19,
MW-20, and MW-22 during July, 2002, wells MW-23, MW-25, MW-27, MW-28, MW-29,
MW-30, MW-31, MW-32, TW4-20, TW4-21, and TW4-22 during June, 2005, wells TW4-23,
TW4-24, TW4-25 during November, 2007, and TWN-series wells in October, 2009 (Figure 1),
yielded average perched zone hydraulic conductivities ranging from approximately 2 x 10-7 cm/s
to 0.01 cm/s. Except for the values of 0.01 cm/s at TWN-16, the range of conductivities was
similar to the range reported by previous investigators at the site (Hydro Geo Chem, Inc [HGC],
2002; HGC, 2005; HGC, 2007b). Downgradient (south to southwest) of the tailings cells,
average perched zone conductivities based on tests at MW-3, MW-5, MW-17, MW-20, MW-22,
and MW-25 ranged from approximately 4 x 10-7 to 1 x 10-4 cm/s Permeability estimates from
these tests were based on pumping/recovery and slug tests analyzed using several different
methodologies.

25 temporary perched zone monitoring wells (the TW4-series wells shown in Figure 1)
have been installed at the site to investigate elevated concentrations of chloroform initially
discovered at well MW-4 in 1999. The chloroform likely originated from two former leach

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 9
fields, one located north of TW4-18, and the other near TW4-19, that received both laboratory
and lavatory wastes in the early years of Mill operation. Some of the coarser-grained and
conglomeratic zones encountered within the perched zone during installation of these wells are
believed to be partly continuous or at least associated with a relatively thin, relatively continuous
zone of higher permeability (International Uranium [USA] Corporation [IUSA] and HGC, 2001).
The higher permeability zone defined by these wells is generally located east to northeast of the
tailings cells at the site, and is hydraulically cross-gradient to upgradient of the tailings cells with
respect to perched groundwater flow.

Based on analyses of pumping tests at MW-4 and drilling logs from nearby temporary
wells, the hydraulic conductivity of this relatively thin coarser-grained zone was estimated to be
as high as 2.5 x 10-3 cm/s. Relatively high conductivities measured at MW-11, located on the
southeastern margin of the downgradient edge of tailings cell #3, and at MW-14, located on the
downgradient edge of tailings cell #4, of 1.4 x 10-3 cm/s and 7.5 x 10-4 cm/s, respectively
(UMETCO, 1993), may indicate that this zone extends beneath the southeastern margin of the
cells. However, this zone of higher permeability within the perched water zone does not appear
to exist downgradient (south-southwest) of the tailings cells. At depths beneath the perched
water table, the zone is not evident in lithologic logs of temporary wells TW4-4 and TW4-6
(located east [cross-gradient] of cell #3, as shown in Figure 5), nor is it evident in wells MW-3,
MW-5, MW-12, MW-15, MW-16, MW-17, MW-20, MW-21, or MW-22, located south to
southwest (downgradient) of the tailings cells, based on the lithologic logs or hydraulic testing of
the wells. The apparent absence of the zone south of TW4-4 and south-southwest of the tailings
cells indicates that it “pinches out” (HGC, 2005).

December 29, 2009 10
To test the potential existence and continuity of this higher permeability zone, and to
refine hydraulic parameter estimates, long term pumping of MW-4 and TW4-19 began in April
2003. MW-26 (TW4-15) was added to the pumping network in August 2003, and TW4-20 was
added in August, 2005. These wells were selected for pumping because they were 1) located in
areas of the perched zone having relatively high transmissivity, and could therefore sustain
relatively high pumping rates, and 2) because the wells were also located in perched water
having relatively high chloroform concentrations, which resulted in significant rates of
chloroform mass removal. As such, the pumping has constituted an interim action to mitigate
chloroform in the perched zone (HGC, 2004).

Analysis of drawdown data collected from wells that responded measurably to pumping
between the start of pumping (April 2003) and November 2003, indicated average hydraulic
conductivities ranging from 4 x 10-5 to 5 x 10-4 cm/s in the area east to northeast of the tailings
cells, assuming the perched zone is unconfined, and from 5 x 10-5 to 1 x 10-3 cm/s if the perched
zone is considered semi-confined (HGC, 2004). Figure 7 shows the approximate area where
detectable drawdowns were measured during the 7 months of pumping. This area is interpreted
to coincide roughly with the zone of higher permeability. Wells located outside this zone that
did not respond measurably to pumping are interpreted to be completed in lower permeability
materials.

2.3.2 Perched Groundwater Flow

Perched groundwater flow at the site has historically been to the south/southwest. As
presented in Section 2.3, Figures 3 through 6 are perched groundwater elevation contour maps
for the years 1990, 1994, 2002, and 2009, respectively. The 1990, 1994, and 2002 maps were
hand contoured because of sparse data. As groundwater elevations indicate, the perched
groundwater gradient changes from generally southwesterly in the western portion of the site, to
generally southerly in the eastern portion of the site. The most significant changes between the
2002 and 2009 water levels result from pumping of wells MW-4, TW4-19, TW4-20, and
MW-26. These wells are pumped to reduce chloroform mass in the perched zone east and
northeast of the tailings cells.

In general, perched groundwater elevations have not changed significantly at most of the
MW-series site monitoring wells since installation, except in the vicinity of the wildlife ponds
and the pumping wells. For example, relatively large increases in water levels occurred between
1994 and 2002 at MW-4 and MW-19, located in the east and northeast portions of the site, as
shown by comparing Figures 4 and 5. These water level increases in the northeastern and
eastern portions of the site are likely the result of seepage from wildlife ponds located near the
piezometers shown in Figure 5, which were installed in 2001 for the purpose of investigating
these changes. The increase in water levels in the northeastern portion of the site has resulted in
a local steepening of groundwater gradients over portions of the site. Conversely, pumping of
wells MW-4, TW4-19, TW4-20, and MW-26 has depressed the perched water table locally and
reduced average hydraulic gradients to the south and southwest of these wells. Perched zone

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc

hydraulic gradients currently range from a maximum of approximately 0.05 ft/ft east of tailings
cell #2 to approximately 0.01 ft/ft downgradient of cell #3, between cell #3 and MW-20.

Perched water discharges in springs and seeps along Westwater Creek Canyon and
Cottonwood Canyon to the west-southwest of the site, and along Corral Canyon to the east of the
site, where the Burro Canyon Formation outcrops. The discharge point located most directly
downgradient of the tailings cells is Ruin Spring. This feature is located approximately 10,000
feet south-southwest of the tailings cells at the site and is depicted on the USGS 7.5-minute quad
sheet for Black Mesa (Figure 8).

2.3.3 Saturated Thickness

The saturated thickness of the perched zone as of the 3rd quarter of 2009 ranges from
approximately 93 ft in the northeastern portion of the site to less than 6 ft in the southwest
portion of the site (Figure 9), and depths to water range from approximately 15 ft in the
northeastern portion of the site (adjacent to the wildlife ponds) to approximately 114 ft at the
southwest margin of tailings cell #3 (Figure 10). The relatively large saturated thicknesses in the
northeastern portion of the site are likely related to seepage from wildlife ponds located near the
piezometers shown in Figure 10.

Although sustainable yields of as much as 4 gpm have been achieved in wells
intercepting the larger saturated thicknesses and higher permeability zones in the northeast
portion of the site, perched zone well yields are typically low (<0.5 gpm) due to the generally

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 13
low permeability of the perched zone. Sufficient productivity can generally be obtained only in
areas where the saturated thickness is greater, which is the primary reason that the perched zone
has been used on a limited basis as a water supply to the north (upgradient) of the site, but not
downgradient of the site.

3. PERCHED GROUNDWATER PORE VELOCITIES

Average rates of movement of a conservative solute in perched groundwater (equivalent
to interstitial or pore velocities) have been calculated for the areas of the perched zone 1)
downgradient of the tailings cells, 2) beneath and immediately upgradient and crossgradient of
the tailings cells, and 3) within the northeastern portion of the site (HGC, 2005, and
Appendix A).

3.1.1 Downgradient of the Tailings cells

As discussed in Section 2.3.2, the nearest discharge point for perched water downgradient
of the tailings cells is Ruin Spring. The average hydraulic gradient between the downgradient
edge of tailings cell #3 and Ruin Spring is approximately 0.013 ft/ft assuming the following:
1) The surveyed elevation of Ruin Spring, based on the USGS topographic map for
Black Mesa, is approximately 5,380 ft amsl.

2) The distance between the downgradient edge of tailings cell #3 and Ruin Spring is
approximately 10,000 ft.

3) The average groundwater elevation at the downgradient edge of tailings cell #3 is
approximately 5,511 ft amsl.

The calculated rate of movement downgradient of the tailings cells was based on 1) an
effective porosity of 0.18, 2) an average hydraulic gradient of 0.013 ft/ft, and 3) geometric
averages of hydraulic conductivities estimated from hydraulic tests at wells located at the
downgradient edge of the cells and south and southwest of the cells. The geometric averages
were based on slug tests performed at MW-3, MW-5, MW-17, MW-20, MW-22, and MW-25

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 16
(HGC, 2002; HGC, 2005), and pump tests performed by Peel Environmental (UMETCO, 1993)
at MW-11, MW-12, MW-14, and MW-15, as summarized in Table 1. Two averages were
calculated; one using conductivities estimated from HGC slug test data analyzed using the
Bouwer-Rice solution (Bouwer and Rice, 1976) and the other using conductivities estimated
from the same data using the KGS solution (Hyder, 1994), as summarized in Table 2. Included in
each average were the results of the pump tests reported in UMETCO, 1993, for MW-11, MW-
12, MW-14, and MW-15. The geometric averages thus calculated were 2.3 x 10-5 and 4.3 x 10-5
cm/s. Assuming the average conductivity ranges from 2.3 x 10-5 to 4.3 x 10-5 cm/s (0.064 ft/day
to 0.120 ft/day), the calculated average rate of movement ranges from 0.0047 ft/day to 0.0087
ft/day (or 1.7 ft/year to 3.2 ft/year).

3.1.2 The Vicinity of the Tailings cells

Perched zone pore velocities beneath and immediately upgradient of the tailings cells
were calculated in HGC, 2005, based on data from wells MW-23, MW-25, MW-27, MW-28,
MW-29, MW-30, MW-31, MW-32, TW4-20, TW4-21, and TW4-22 (Table 3). Estimated
hydraulic conductivities range from approximately 2 x 10-7 to 1 x 10-4 cm/s and yield a geometric
average of approximately 3 x 10-5 cm/s or 31 ft/yr. Using hydraulic gradients in the vicinity of
each well, the estimated conductivity at each well, and an effective porosity of 0.18, the
estimated pore velocities ranged from 49.5 ft/year at TW4-21, to 0.010 ft/year at MW-23, and
have a geometric average of approximately 4.5 ft/year. Hydraulic gradients in the vicinity of
most of these wells have not changed significantly since 2005, nor have the estimated pore

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 17
velocities. The largest changes have occurred in wells located near pumping wells due to
periodic changes in pumping rates.

East of the tailings cells, within the area of the chloroform plume (Figure 7), perched
zone pore velocities are calculated using hydraulic conductivities reported in HGC, 2004, as
summarized in Tables 4 and 5. Wells TW4-5, TW4-9, and TW4-1 are on a line subparallel to the
hydraulic gradient in that area. Using the (arithmetic) average hydraulic conductivity of 321 ft/yr
for these wells (assuming unconfined conditions) a hydraulic gradient of 0.029 ft/ft, and an
effective porosity of 0.18, the estimated pore velocity is 52 ft/yr. If semi-confined conditions are
assumed (and that flow is primarily through only coarser-grained zones defined by drilling logs
as discussed in HGC, 2004), an average hydraulic conductivity of 663 ft/yr is calculated, and the
pore velocity is estimated as 110 ft/yr. The arithmetic average conductivity was used because
the range for these three wells is within an order of magnitude.

3.1.3 The Northeastern Portion of the Site

Perched zone pore velocities in the northeastern portion of the site are provided in Table
6 and Appendix A. The geometric average hydraulic conductivity of the TWN-series hydraulic
tests is approximately 5.3 x 10-5 cm/s or 54 ft/yr. Using hydraulic gradients in the vicinity of
each TWN-series well, the estimated conductivity at each well, and an effective porosity of 0.18,
the calculated pore velocities range from 0.04 feet per year (ft/yr) at TWN-7 to 762 ft/yr at
TWN-16, with a geometric average of approximately 7 ft/yr. The calculated pore velocity at
TWN-16 is the highest of any perched zone well at the site due to the relatively high

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 18
conductivity of 0.01 cm/s estimated for the well. This suggests the presence of a relatively thin
high permeability zone (or set of such zones) analogous to that inferred to exist east of the
tailings cells near MW-4. Although none of the nearby wells appear to intercept such a zone,
suggesting that it is likely not continuous additional data might reveal the continuity of such a
zone.

Appendix A also provides a discussion of nitrate distribution with respect to permeability
and perched zone pore velocities in the northeastern portion of the site. Areas of elevated
perched zone nitrate (> 5 mg/L) that exist northeast of and proximal to the Mill are referred to as
Area 1 and Area 2 respectively (Figure 11). Average perched zone pore velocities along
hypothetical pathlines oriented with the long axes of these areas of elevated nitrate
concentrations are calculated as approximately 0.55 ft/yr to 7 ft/yr for Area 1 and 23 ft/yr for
Area 2 using geometric averages of hydraulic conductivity estimates along the pathlines
(Appendix A). These velocities are insufficient to transport nitrate from the upgradient to the
downgradient portions of the two areas within the approximate 30 year operational time of the
Mill, suggesting that 1) actual rates are faster than calculated using the geometric averages of the
estimated hydraulic conductivities, 2) each nitrate area has resulted from more than one localized
seepage area and/or one or more diffuse, distributed seepage areas located upgradient of the
tailings cells, or 3) the nitrate distribution results from a combination of these factors. With
regard to 2) above, more than one seepage area may have received water from the same source
resulting in similar seepage chemistry at more than one areal location. Furthermore, some
seepage areas may have existed prior to Mill construction, and contributed nitrate for decades
prior to the existence of any source areas related to Mill operation. Another complicating factor

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 19
is that hydraulic gradients have changed over time over portions of the site. For example,
hydraulic gradients have changed as a result of seepage from the wildlife ponds, and would be
expected to have changed in response to any other sources of seepage present prior to Mill
construction and operation.

The higher the pore velocities, the fewer localized seepage areas are needed to distribute
the nitrate detected in both Area 1 and Area 2. Higher pore velocities would result in spreading
of nitrate from each potential source location over a larger area. Past and present pore velocities
may be high enough to support minimal contributing seepage locations if 1) greater weight were
given to the highest conductivity estimates when calculating the averages or 2) flow is primarily
through one or more relatively thin, relatively continuous higher permeability zones similar to
that inferred to exist in the vicinity of MW-4, located east of the tailings cells within an area of
elevated chloroform (HGC, 2007a). Because the estimated hydraulic conductivities in Table 6
are averages over the entire saturated thicknesses at the estimation points, the conductivity of a
relatively thin horizon or horizons through which most of the flow was occurring would be
underestimated as would the effective pore velocity.

The presence of higher permeability horizons within both Area 1 and Area 2 (by analogy
with the area near MW-4) would allow greater spreading of perched zone nitrate within the 30
year operational time history of the Mill. Fewer localized seepage areas could then be called
upon to yield the observed nitrate distributions. The high hydraulic conductivity estimated at
TWN-16 indicates the possible existence of such a horizon within Area 1. Such a zone does not
appear to be penetrated by other TWN-series wells near and within Area 1, suggesting that any

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 20
higher permeability zone penetrated by TWN-16 is not continuous over Area 1. However,
additional data might reveal the presence of a zone analogous to that near MW-4 that could have
transported nitrate over longer distances.

4. SUMMARY

Perched groundwater at the site is hosted primarily by the Burro Canyon Formation,
which consists of a relatively hard to hard, fine- to medium-grained sandstone containing
siltstone, shale and conglomeratic materials. The Burro Canyon Formation is separated from the
underlying regional Navajo/Entrada aquifer by approximately 1000 ft of Morrison Formation
and Summerville Formation materials having a low average vertical permeability. The Brushy
Basin Member of the Morrison Formation is a shale that immediately underlies the Burro
Canyon Formation and forms the base of the perched water zone at the site. Based on hydraulic
tests at perched zone monitoring wells, the hydraulic conductivity of the perched zone ranges
from approximately 2 x 10-7 to 0.01 cm/s.

Perched water flow is generally from northeast to southwest across the site. Beneath and
downgradient of the tailings cells, on the west side of the site, perched water flow is south-
southwest. On the eastern side of the site perched water flow is more southerly. Perched water
generally has a low quality, with total dissolved solids ranging from approximately 1,100 to
7,900 mg/L, and is used primarily for stock watering and irrigation north (upgradient) of the site.

Depths to perched water range from approximately 15 ft near the wildlife ponds in the
northeastern portion of the site to approximately 114 ft at the southwestern margin of the tailings
cells. Saturated thicknesses range from approximately 93 ft near the wildlife ponds to less than 6
ft in the southwest portion of the site, downgradient of the tailings cells. Although sustainable
yields of as much as 4 gpm have been achieved in wells penetrating higher transmissivity zones,

Site Hydrogeology & Est. GW Travel Times
H:\718000\hydrpt09b\report\hydr122909 Final.doc
December 29, 2009 22
well yields are typically low (< 0.5 gpm) due to the generally low permeability of the perched
zone.

In general, the highest permeabilities and well yields are in the area of the site
immediately northeast and east (upgradient to crossgradient) of the tailings cells. A relatively
continuous, higher permeability zone has been inferred to exist in this portion of the site which is
associated with an area of elevated chloroform concentrations that most likely originated from
two former leach fields that received both laboratory and lavatory wastes in the early years of
Mill operation. Hydraulic tests at wells located in this area indicate hydraulic conductivities in
the range of 10-3 to 10-4 cm/s. Using data from TW4-5, TW4-9, and TW4-1 (which form a north-
south line approximately parallel to perched water flow east of the tailings cells) pore velocities
are estimated to range from approximately 52 to 110 ft/yr in this area.

Hydraulic conductivities in the northeastern portion of the site, upgradient of the tailings
cells (within elevated nitrate Area 1), are generally in the intermediate range of values estimated
for the site, although the highest conductivity estimated for the site (approximately 0.01 cm/s),
and one of the lowest conductivities estimated for the site (approximately 4 x 10-7 cm/s) occur in
this area. Hydraulic tests of TWN-series wells yield a geometric average of approximately 5.3 x
10-5 cm/s or 54 ft/yr. Calculated pore velocities range from approximately 0.04 to 762 ft/yr and
have a geometric average pore velocity of approximately 7 ft/yr.

Permeabilities beneath and immediately upgradient of the tailings cells are generally
within the intermediate to low range of values estimated for the site. Hydraulic conductivity

estimates for wells MW-23, MW-25, MW-27, MW-28, MW-29, MW-30, MW-31, MW-32,
TW4-20, TW4-21, and TW4-22 range from approximately 2 x 10-7 to 2 x 10-4 cm/s and yield a
geometric average of approximately 3 x 10-5 cm/s or 31 ft/yr. Estimated pore velocities ranged
from 0.010 ft/yr to 49.5 ft/yr and have a geometric average of approximately 4.5 ft/year.

Permeabilities downgradient of the tailings cells are generally low. Combined with
shallow hydraulic gradients, average calculated pore velocities downgradient of the tailings cells
are among the lowest on site. Hydraulic tests at wells located at the downgradient edge of the
cells, and south and southwest of the cells (MW-3, MW-5, MW-11, MW-12, MW-14, MW-15,
MW-17, MW-20, MW-22, and MW-25), yielded geometric average hydraulic conductivities of
2.3 x 10-5 and 4.3 x 10-5 cm/s (23 ft/yr and 44 ft/yr, respectively) depending on the testing and
analytical method. Assuming the average conductivity ranges from 2.3 x 10-5 to 4.3 x 10-5 cm/s,
the calculated average pore velocity ranges from 1.7 ft/year to 3.2 ft/year.

With regard to nitrate distribution (as discussed in Appendix A), within Area 1, a
geometric average pore velocity along the indicated pathline of as high as 7 ft/yr is calculated,
and in the western portion of Area 2, a geometric average pore velocity along the indicated
pathline of 23 ft/yr is calculated (Figure 11). These velocities are insufficient to transport nitrate
from the upgradient to the downgradient portions of either area within the approximate 30 year
operational time of the Mill, suggesting that 1) actual pore velocities are higher than calculated
using the geometric averages of the estimated hydraulic conductivities, 2) each nitrate area has
resulted from more than one localized seepage areas and/or one or more diffuse, distributed
seepage areas located upgradient of the tailings cells, or 3) the nitrate distribution results from a

combination of these factors. With regard to item 2) above, more than one seepage area may
have received water from the same source resulting in similar seepage chemistry at more than
one areal location. Furthermore, some seepage areas may have existed prior to Mill construction,
and contributed nitrate for decades prior to the existence of any seepage areas related to Mill
operation.

The higher the pore velocities, the fewer localized seepage areas are needed to distribute
the nitrate detected in both Area 1 and Area 2. Higher pore velocities would result in spreading
of nitrate from each potential source location over a larger area. Past and present pore velocities
may be high enough to support minimal contributing seepage locations if 1) greater weight were
given to the highest conductivity estimates when calculating the averages or 2) flow is primarily
through one or more relatively thin, relatively continuous higher permeability zones similar to
that inferred to exist in the vicinity of MW-4, located east of the tailings cells within an area of
elevated chloroform (HGC, 2007a). Because the estimated hydraulic conductivities in Table 6
are averages over the entire saturated thicknesses at the estimation points, the conductivity of a
relatively thin horizon or horizons through which most of the flow was occurring would be
underestimated as would the effective pore velocity.

The presence of higher permeability horizons within both Area 1 and Area 2 (by analogy
with the area near MW-4) would allow greater spreading of perched zone nitrate within the 30
year operational time history of the Mill. Fewer localized seepage areas could then be called
upon to yield the observed nitrate distributions. The high hydraulic conductivity estimated at
TWN-16 indicates the possible existence of such a horizon within Area 1. Such a zone does not

appear to be penetrated by other TWN-series wells near and within Area 1, suggesting that any
higher permeability zone penetrated by TWN-16 is not continuous over Area 1. However,
additional data might reveal the presence of a zone analogous to that near MW-4 that could have
transported nitrate over longer distances.

1. INTRODUCTION

This report describes the hydraulic testing of 19 new temporary perched zone groundwater
monitoring wells at the White Mesa Uranium Mill (the “Mill” or the “site”). The wells, designated
TWN-1 through TWN-19 as shown in Figure A.1, were installed to better define the distribution of
nitrate and chloride in the perched groundwater. All wells were completed in nominal 6 ¾ inch
diameter boreholes using flush-thread, 4-inch diameter PVC casing and factory slotted screen. Wells
TWN-11 through TWN-19 were the last round of TWN-series wells to be installed and development
of these wells was completed during the week prior to the testing. Wells TWN-1 through TWN-10
were tested first to allow more time for water levels in the newest wells (TWN-11 through TWN-19)
to stabilize.

Hydraulic testing consisted of slug tests conducted between October 19 and October 26,
2009. Test data were analyzed to estimate perched zone hydraulic properties in the vicinity of each
new well. Slug testing and analysis procedures were similar to those used in previous testing at the
site during July 2002 and June, 2005 as described in Hydro Geo Chem, Inc. (HGC), 2002, and HGC,
2005.

2. HYDRAULIC TESTING

HGC personnel conducted hydraulic tests between October 19 and October 26, 2009. The
hydraulic tests consisted of slug tests performed in the same manner as described in HGC, 2002, and
HGC, 2005. Hydraulic tests were performed at all TWN-series perched well installations and at
existing well MW-24. The test results at MW-24 are described in a separate document. The purpose
of the tests was to estimate hydraulic parameters (primarily hydraulic conductivity) in the vicinity of
each new well. The same slugs and electric water level meter were used in both the current testing
event and the June 2005 testing event. The submersible 0-30 pounds per square inch absolute (psia)
Level Troll 500TM pressure transducers and data loggers used in the current tests were similar to
those used in previous tests.

2.1 Data Collection

Two slugs consisting of sealed, pea-gravel-filled, schedule-80 PVC pipe, one approximately
3 feet long, and one approximately 4 feet long, as described in HGC, 2002, were used for the tests.
The 3-foot slug had a larger diameter and displaced approximately 0.75 gallons of water. The 4-foot
slug had a smaller diameter and displaced approximately 0.47 gallons. Typically, the 3-foot,
0.75-gallon displacement slug was used. If a test using the 3-foot slug was slow due to low
permeability conditions, a concurrent test could be started in the next well using the 4-foot, 0.47-
gallon slug. Two Level-TrollJ data loggers were available to allow two wells to be tested
simultaneously.

H:\718000\hydrpt09b\report\App A-TWN hydraulic tests 122909 Final.doc

In all cases, water level data were collected automatically using a Level-TrollJ data logger
and by hand using the electric water level meter. Automatically logged data were collected at
5-second intervals except at TWN-16, where a 1-second interval was used. Hand-collected data
were obtained more frequently in the first few minutes of each test when water levels were changing
rapidly, then more slowly as the rate of water level change diminished.

Prior to each test, the static water level in each well was measured by hand using the electric
water level meter. The data logger was then lowered to a depth of approximately 8 to 10 feet below
the static water level, and background pressure readings were collected for approximately 30 to 60
minutes prior to beginning a test. The purpose of collecting the background data was to allow
correction of test data for any trends in water levels measured at the wells. Typically, 30 minutes of
background readings were collected for TWN-1 through TWN-10, and 1 hour of background
readings for TWN-11 through TWN-19. The longer interval was used for wells TWN-11 through
TWN-19 because these were the most recently installed wells and there was a higher likelihood that
water levels in these wells had not yet stabilized after installation and development. Wells TWN-1
through TWN-10 were also tested first to give the more recently installed wells more time to
stabilize.

Once background data were collected, the slug and electric water level meter sensor were
then suspended in the well just above the static water level. Each test commenced by lowering the
slug to a depth of approximately 2 feet below the static water level over a period of a few seconds
and taking water level readings by hand as soon as possible afterwards. Upon completion,

equipment pulled from each well was rinsed with clean water prior to its use in the next test.
Automatically logged data were checked, backed up on the hard drive of a personal computer, and
e-mailed to HGC’s Tucson office daily for review and processing.

2.2 Data Analysis

Data were analyzed using AqtesolvTM (HydroSOLVE, 2000), a computer program developed
and marketed by HydroSOLVE, Inc. In preparing the automatically logged data for analysis, the
total number of records was reduced. In general, all data collected in the first 50 seconds were
retained, then every 2nd, then 3rd, then 4th, etc. record was retained for analysis. For example, if the
first 10 records were retained (50 seconds of data at 5-second intervals), the next records to be
retained would be the 12th, the 15th, the 19th, the 24th, etc. In general, the maximum measured rise
in water levels was slightly below what would be expected considering the slug volume, the volume
in the 4-inch-diameter casing, and the volume in the annular space between the casing and the 6
¾-inch-diameter bore. Assuming a 30 percent effective porosity for the filter pack, the expected rise
in water level is approximately 1 foot per gallon. The maximum expected rise for the 3-foot,
0.75-gallon slug is therefore about 0.75 feet, and for the 4-foot, 0.47-gallon slug, about 0.47 feet. If
only the 4-inch diameter casing is considered, a maximum rise of approximately 1.12 ft is expected
for the 0.75 gallon slug, and approximately 0.75 ft for the 0.47 gallon slug.

Data were analyzed using two solution methods: the KGS unconfined method (Hyder et al.,
1994) and the Bouwer-Rice unconfined method (Bouwer and Rice, 1976). When filter pack

A-6
porosities were required by the analytical method, a value of 30 percent was used. The saturated
thickness was taken to be the difference between the static water level measured just prior to the test
and the depth to the Brushy Basin contact as defined in the drilling logs (Table A.1). In cases where
the static water level was below the top of the screened interval, the saturated thickness was also the
effective screen length. In cases where the static water level was above the top of the screened
interval, the partial penetration of the well was considered in the analysis.

Background data were analyzed for any obvious trends and when detected were used to
correct subsequent test readings. Background trends were used to correct data from wells TWN-2,
TWN-9, TWN-10, TWN-11, and TWN-12. (Data from TWN-7 were corrected for barometric
pressure changes as discussed below.) The method for background correction was to fit a linear or
logarithmic function to the background data then use that function to correct the subsequent test
readings. In all cases, the corrections were a small fraction of the total displacement created by the
slugs. Plots of raw and corrected displacements for these wells are provided in Appendix A.1.

Barometric pressure was recorded throughout each test using a BaroTrollTM pressure
transducer and logger. In all cases, except at TWN-7, the test duration was short enough that the
impact of changing barometric pressure could be ignored. The overnight test at TWN-7 required a
correction for atmospheric pressure changes. Good agreement exists between hydraulic conductivity
estimates made by different solution methods after correcting the data. The interpretation at TWN-7
is complicated by the extremely low hydraulic conductivity, the consequent small rate of change in

App A: Perched Nitrate Monitoring Well Hydraulic Tests
H:\718000\hydrpt09b\report\App A-TWN hydraulic tests 122909 Final.doc
December 29, 2009
A-7
water levels during the test, and by the possibility that the relationship between changes in water
level and changes in barometric pressure was not constant over the test.

The behavior of water levels at TWN-7 in relation to changes in barometric pressure is
consistent with the discussion in HGC, 2004. Water level changes in the perched wells are impacted
by instantaneous transmission of barometric pressure changes down the well casings and delayed
(lagged and attenuated) transmission of pressure changes to the water table at locations remote from
the wells. The lag and attenuation at remote locations result from vertically downward propagation
of pressure changes through the low permeability vadose materials.

The KGS solution allows estimation of both specific storage and hydraulic conductivity,
while the Bouwer-Rice solution allows estimation of only the hydraulic conductivity. The Bouwer-
Rice solution is valid only for the straight-line portion of the data that results when the log of
displacement is plotted against time, and is insensitive to both storage and the specified initial water
level rise. Typically, only the later-time data are interpretable using Bouwer-Rice. The KGS
solution generally allows a fit to both early and late time data, and is sensitive to storage and the
specified initial water level rise. Both solutions were used for comparison. Automatically logged
and hand-collected data were analyzed separately using both solution methods. The hand-collected
data, therefore, served as an independent data set and a check on the accuracy of the automatically
logged data.

2.3 Results

The results of the analyses are provided in Table A.2 and Appendix A.2. Appendix A.2
contains plots generated by AqtesolveJ that show the quality of fit between measured and simulated
results, and reproduce the parameters used in each solution. Estimates of hydraulic conductivity
range from 3.6 x 10-7 centimeters per second (cm/s) at TWN-7 to 0.0142 cm/s at TWN-16. The
value of 0.0142 cm/s estimated using the KGS solution for the test at TWN-16 is higher than any
value previously estimated for the perched zone. Except for the hydraulic conductivity estimate at
TWN-16, values are within the range previously measured at the site.

In general, the agreement between hydraulic conductivities estimated from the KGS and
Bouwer-Rice solutions is good, and values agree within a factor of 2 except at TWN-4, where the
estimates differed by a factor of about 63, and at TWN-16, where the estimates differed by a factor
of 2.2.

The agreement between estimates obtained from automatically logged and hand-collected
data is also good. In all but three cases, the estimates based on automatically logged and
hand-collected data using the KGS solution are within a factor of 2, and in the other three cases are
within a factor of 3. Estimates obtained from automatically logged and hand-collected data using the
Bouwer-Rice solution are also close: identical or within a factor of 2 in all cases except at TWN-13,
where the estimates differ by a factor of 3.

Specific storage estimates of 0.1 obtained at TWN-10 and TWN-13 using KGS are
anomalously high. These estimates suggest that these tests were impacted by near-well storage
effects not encountered at other wells.

3. ESTIMATED PERCHED WATER TRAVEL TIMES IN THE NORTHEASTERN
PORTION OF THE SITE

Average perched groundwater travel times in the vicinity of the TWN-series wells are
estimated based on the hydraulic conductivity estimates obtained from the wells and hydraulic
gradients calculated from site water levels. This method is identical to that presented in HGC, 2005.
Because the hydraulic conductivity estimates represent values vertically averaged over the measured
saturated thicknesses of the wells, the calculated travel times also represent values averaged over the
saturated thicknesses.

Except for the high hydraulic conductivity of 0.0142 cm/s estimated for TWN-16 using the
KGS solution, hydraulic conductivity estimates from the new wells are within the range previously
reported for the site. Perched zone hydraulic conductivities at the site are generally highest in the
area northeast and east (upgradient to crossgradient) of Tailings Cell #2.

Figure A.2 is a contour map of December, 2009 perched water level data. This map was
generated by gridding the raw data using ordinary linear kriging with a linear variogram. The general
direction of perched water flow inferred from the water level contours is to the south-southwest.
Flow is complicated immediately northeast of the Mill site by the groundwater mound associated
with the wildlife ponds. Perched water flow at many of the new installations located immediately
north of the ponds is to the north-northwest, and a broad region of relatively flat hydraulic gradient
exists to the northwest of the ponds. The highest measured water level was at TWN-12, the most
northern of the newly installed TWN-series wells.

Table A.3 provides the average perched water pore (interstitial) velocities in the vicinities of
the new wells based on hydraulic conductivity estimates and hydraulic gradients calculated from
water levels shown on Figure A.2. Hydraulic conductivities shown in Table A.3 are averages of
KGS and Bouwer-Rice estimates shown in Table A.2. An effective porosity of 18 percent was used
in the calculations. The heavy green lines in Figure A.2 indicate the positions and lengths over
which the perched zone hydraulic gradients were calculated. The method of calculation is
substantially the same as described in HGC, 2005.

As indicated, the calculated pore velocities range from 0.04 feet per year (ft/yr) at TWN-7 to
762 ft/yr at TWN-16. Calculated velocities at TWN-1, TWN-4, TWN-5, TWN-6, TWN-8, TWN-12,
TWN-16, TWN-18, and TWN-19 are greater than 10 ft/yr; velocities at TWN-2, TWN-3, TWN-8,
TWN-9, TWN-10, TWN-11, and TWN-15 are between 1 and 10 ft/yr; and velocities at TWN-7,
TWN-13, TWN-14, and TWN-17 are less than 1 ft/yr.

Figure A.3 is a map posting nitrate concentrations obtained from samples of perched zone
wells that shows the approximate areas where nitrate concentrations exceed 5 mg/L. These areas are
hereafter referred to as areas of elevated nitrate. Figure A.4 is a water level contour map showing
these same areas. The northeastern area of elevated nitrate is referred to as Area 1, and the central
area as Area 2..Area 1 consists of two sub-areas, the northernmost associated with TWN-17 and
TWN-19, and the other associated with TWN-9 and PIEZ-1. Areas 1 and 2 are separated by a
groundwater mound associated with the wildlife ponds. Areas 1 and 2 are generally elongated in the
northeast-southwest direction, roughly parallel to the perched hydraulic gradient. The eastern portion

of the central area contains a lobe (or spur) that is elongated in the north-south to south-southeast
direction.

Average perched groundwater pore velocities are calculated for two hypothetical pathlines
through elevated nitrate Areas 1 and 2. These pathlines are shown in Figure A.4. The northeastern
pathline (from TWN-17 to TWN-9) is associated with Area 1 (northeast of the wildlife ponds) and
the central pathline (from TWN-2 to MW-11) is associated with Area 2 (west and southwest of the
wildlife ponds). These pathlines, although subparallel to the long axes of portions of the two areas,
are considered hypothetical because they are not always parallel to the current hydraulic gradient.

The average hydraulic gradient along the Area 1 pathline is approximately 0.012 ft/ft, and
along the Area 2 pathline, 0.025 ft/ft. The geometric mean hydraulic conductivity along the Area 1
pathline (based on estimates at TWN-9, TWN-14, and TWN-17) is approximately 8 ft/yr, and along
the Area 2 pathline (based on estimates at TWN-2, TW4-24, and MW-11), approximately 165 ft/yr.
Assuming a porosity of 18 percent, average pore water velocities of 0.55 ft/yr for the Area 1 pathline
and 23 ft/yr for the Area 2 pathline are calculated. A larger velocity of approximately 7 ft/yr is
calculated for the Area 1 pathline if the hydraulic conductivity for nearby well TWN-16 is
substituted for that of TWN-17 (which yields a geometric mean hydraulic conductivity [based on
estimates at TWN-9, TWN-14, and TWN-16] of approximately 100 ft/yr).

4. DISCUSSION

Perched water pore (interstitial) velocities in the vicinities of the new wells are calculated
(using averages of KGS and Bouwer-Rice hydraulic conductivity estimates) to range from
approximately 0.04 ft/yr at TWN-7 to 762 ft/yr at TWN-16. Calculated average velocities along the
two hypothetical pathlines shown in Figure A.4 are 0.55 ft/yr to 7 ft/yr for nitrate Area 1 and 23 ft/yr
for nitrate Area 2. Calculated velocities are insufficient to move nitrate from the upgradient to the
downgradient portions of either area during the approximately 30 years of site operation. This
suggests that 1) actual velocities are higher than calculated using the geometric averages of the
estimated hydraulic conductivities, 2) each nitrate area has resulted from more than one localized
seepage area and/or one or more diffuse, distributed seepage areas located upgradient of the tailings
cells, or 3) the nitrate distribution results from a combination of these factors. With regard to item 2)
above, more than one seepage area may have received water from the same source resulting in
similar seepage chemistry at more than one areal location. Furthermore, some seepage areas may
have existed prior to Mill construction, and contributed nitrate for decades prior to the existence of
any seepage areas related to Mill operation. Hydraulic gradients have changed as a result of seepage
from the wildlife ponds, and would be expected to have changed in response to any other sources of
seepage present prior to Mill construction and operation.

The higher the pore velocities, the fewer seepage areas are needed to distribute the nitrate
detected in both Area 1 and Area 2. Higher pore velocities would result in spreading of nitrate from
each potential source location over a larger area. Past and present pore velocities may be high enough

to support minimal contributing seepage locations if 1) greater weight were given to the highest
conductivity estimates when calculating the averages or 2) flow is primarily through one or more
relatively thin, relatively continuous higher permeability zones similar to that inferred to exist in the
vicinity of MW-4, located east of the tailings cells within an area of elevated chloroform (HGC,
2007). Because the estimated hydraulic conductivities in Table A.2 are averages over the entire
saturated thicknesses at the estimation points, the conductivity of a relatively thin horizon or
horizons through which most of the flow was occurring would be underestimated as would the
effective pore velocity. For example, if nearly all the flow were occurring within a horizon with a
thickness that was only 10 percent of the total saturated thickness, then the conductivity of that
horizon could be nearly 10 times as high as the average estimated over the entire saturated thickness,
and the effective pore velocity nearly 10 times higher than estimated using the vertically averaged
conductivity. Based on hydraulic test data and drilling logs at or near MW-4, the conductivity of a
relatively thin, relatively continuous higher permeability zone penetrated by MW-4 was estimated to
be as much as 5 to 10 times higher than the vertically averaged conductivity estimates (HGC, 2007).

The presence of higher permeability horizons within both Area 1 and Area 2 (by analogy with
the area near MW-4) would allow greater spreading of perched zone nitrate within the 30 year
operational time history of the Mill. Fewer localized seepage areas could then be called upon to yield
the observed nitrate distributions. The high hydraulic conductivity estimated at TWN-16 indicates
the possible existence of such a horizon within Area 1. Such a zone does not appear to be penetrated
by other TWN-series wells near and within Area 1, suggesting that any higher permeability zone
penetrated by TWN-16 is not continuous over Area 1. However, additional data might reveal the

distances.

5. CONCLUSIONS

Hydraulic conductivity estimates based on slug tests at the new wells range from 3.6 x 10-7
cm/s at TWN-7 to 0.014 cm/s at TWN-16. The value of 0.014 cm/s, based on the test conducted at
TWN-16 and obtained using the KGS solution, is higher than any previously reported value for the
perched zone. The average of the KGS and Brouwer-Rice results at TWN-16 was 0.01 cm/s. Except
for estimates obtained at TWN-16, the range of hydraulic conductivities estimated for the new wells
is within the range of perched zone values previously reported for the site. Perched zone hydraulic
conductivities at the site are generally highest in the area northeast to east (upgradient to
crossgradient) of Tailings Cell #2.

Perched water pore (interstitial) velocities in the vicinities of the new wells are calculated to
range from 0.04 feet per year (ft/yr) at TWN-7 to 762 ft/yr at TWN-16. Calculated velocities at
TWN-1, TWN-4, TWN-5, TWN-6, TWN-8, TWN-12, TWN-16, TWN-18, and TWN-19 are greater
than 10 ft/yr; velocities at TWN-2, TWN-3, TWN-8, TWN-9, TWN-10, TWN-11, and TWN-15 are
between 1 and 10 ft/yr; and velocities at TWN-7, TWN-13, TWN-14, and TWN-17 are less than 1
ft/yr.

Areas of elevated perched zone nitrate that exist northeast of and proximal to the Mill are
referred to as Area 1 and Area 2 respectively. Average perched zone pore velocities along
hypothetical pathlines oriented with the long axes of these areas of elevated nitrate concentrations are
calculated as approximately 0.55 ft/yr to 7 ft/yr for Area 1 and 23 ft/yr for Area 2 using geometric

averages of hydraulic conductivity estimates along the pathlines. These velocities are insufficient to
transport nitrate from the upgradient to the downgradient portions of either area within the
approximate 30 year operational time of the Mill, suggesting that 1) actual pore velocities are higher
than calculated using the geometric averages of the estimated hydraulic conductivities, 2) each nitrate
area has resulted from more than one localized seepage area and/or one or more diffuse, distributed
seepage areas located upgradient of the tailings cells, or 3) the nitrate distribution results from a
combination of these factors. With regard to item 2) above, more than one seepage area may have
received water from the same source resulting in similar seepage chemistry at more than one areal
location. Furthermore, some seepage areas may have existed prior to Mill construction, and
contributed nitrate for decades prior to the existence of any seepage areas related to Mill operation.
Hydraulic gradients have changed as a result of seepage from the wildlife ponds, and would be
expected to have changed in response to any other sources of seepage present prior to Mill
construction and operation.

Attachment 6: Calculation to Evaluate Potential Tailings Cell Source

Assume:
 Nitrate Concentration in Tailings Solution = 290 mg/L
 Nitrate Concentration in un-impacted Groundwater = 1 mg/L
 Average Plume Concentration = 30 mg/L

Mixing Equation: Ct*Vt + Cg*Vg = Cm*Vm (eq 1)
Where: Ct = Concentration of nitrate in tailings solutions
Vt = Volume of tailings solutions
Cg = Concentration of nitrate in unimpacted groundwater
Vg = Volume of unimpacted groundwater
Cm = Concentration of nitrate in mixture
Vm = Volume of mixture
Another Equation: Vt + Vg = Vm (eq 2)
Substituting eq2 in eq1: Ct*Vt + Cg*Vg = Cm*( Vt + Vg) (eq 3)
Substitute Nitrate Concentrations in eq3
290*Vt + 1*Vg = 30*( Vt + Vg)
290*Vt + 1*Vg = 30*Vt + 30*Vg
260*Vt = 29*Vg
Vt = 29/260*Vg = 0.11* Vg
The volume of tailings solution would have to be eleven percent of the volume of
unimpacted groundwater in the mixture.
