1.0 INTRODUCTION
The Utah Department of Environmental Quality ("UDEQ") Division of Radiation
Control ("DRC") noted in a Request dated September 30, 2008 (the "Request"), for a
Voluntary Plan and Schedule to Investigate and Remediate Nitrate Contamination at the
White Mesa Uranium Mill (the "Mill") (the "Plan"), that nitrate levels have exceeded the
State water quality standard of 10 mglL in certain monitoring wells. As a result of the
Request, Denison Mines (USA) Corp. ("DUSA") entered into a Stipulated Consent
Agreement (the "Agreement") with the Utah Water Quality Board in January 2009 which
directed the preparation of a Nitrate Contamination Investigation Report and Quarterly
Nitrate Monitoring Reports. A subsequent letter dated December 1, 2009, among other
things, recommended that DUSA also address elevated chloride concentration in the
Nitrate Monitoring Reports.
This is the Quarterly Nitrate Monitoring Report, as required under the Agreement, State
ofUDEQ Docket No. UGW-09-03 for the fourth Quarter of2010 (the "Quarter").
2.0 GROUNDWATER NITRATE MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, temporary chloroform contaminant investigation wells and temporary nitrate
investigation wells is attached under Tab A. Nitrate samples and measurements taken
during this reporting period (October through December 2010), are discussed in the
remainder of this section.

N:lRequired ReportslNilrate Quarterly Monitoring Report120 10 Q412010 Q4 Nilrate Report text.doc
As indicated in Table 1, nitrate monitoring was performed in all of the nitrate monitoring
wells, the UWLP, and Piezometers 1,2, and 3. Analytical data for all of the nitrate wells,
piezometers and the UWLP are included in Tab G.
Nitrate and chloride are also monitored in all of the Mill's groundwater monitoring wells
and chloroform investigation wells. Data from those wells for the Quarter are
incorporated in certain maps and figures in this report but are discussed in their respective
programmatic reports.
2.1.2 Parameters Analyzed
Locations sampled during this reporting period were analyzed for the following
constituents:
• Inorganic Chloride
• Nitrate plus Nitrite as Nitrogen (referred to herein as nitrate)
Use of analytical methods consistent with the requirements of the White Mesa Uranium
Mill Groundwater Quality Assurance Plan, Revision 6, March 22,2010 (the "QAP") was
confirmed for all analytes, as discussed later in this report.
2.1.3 Groundwater Head and Level Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant
to Part 1.E.3 of the Groundwater Discharge Permit (the "GWDP") (June 17,2010):
• The quarterly groundwater compliance monitoring wells (including newly
installed MW-33, MW-34, and MW-35 if water is present).
• Existing well MW-4 and all of the temporary chloroform investigation wells.
• Piezometers -P-1, P-2, P-3, P-4 and P-5.
• MW-20 and MW-22
• Nitrate monitoring wells.
• In addition to the above, depth to water measurements are routinely observed in
conjunction with sampling events for all wells sampled during quarterly and
accelerated efforts, regardless ofthe sampling purpose.
All well levels used for groundwater contour mapping were measured and recorded
within 5 calendar days of each other as indicated by the measurement dates in the
summary sheet under Tab C.
2.2 Sampling Methodology and Equipment and Decontamination Procedures
The QAP provides a detailed presentation of procedures utilized for groundwater
sampling activities under the GWDP (June 17,2010).
2
N:lRequired ReportslNitrale Quarterly Moniloring Report12010 Q412010 Q4 Nitrate Report lexl,doc
The sampling methodology, equipment and decontamination procedures that were
performed for the nitrate contaminant investigation, as summarized below, are consistent
with the QAP.
2.2.1 Well Purging and Depth to Groundwater
A list of the wells in order of increasing nitrate contamination is generated quarterly. The
order for purging is thus established. The list is included with the Field Data Worksheets
under Tab B. Mill personnel start purging with all of the non-detect wells and then move
to the more contaminated wells in order of nitrate contamination, starting with the wells
having the lowest nitrate contamination.
Before leaving the Mill office, the pump and hose were decontaminated using the
cleaning agents described in Section 6.2.5 of the QAP. Mill personnel then proceed to
the first well which is the well with the lowest concentration of nitrate based on the
previous quarter's sampling results. Well depth measurements are taken and the two
casing volumes are calculated (measurements are made using the same instrument used
for the monitoring wells under the Mill's GWDP). The Grundfos pump (a 6 to 10 gallon
per minute [gpm] pump) is then lowered to the bottom of the well and purging is begun.
At the first well, the purge rate is established for the purging event by using a calibrated 5
gallon bucket. After the evacuation of the well has been completed, the well is sampled
when possible, and the pump is removed from the well and the process is repeated at each
well location moving from the least contaminated to most contaminated well. If sample
collection is not possible due to the well being purged dry a sample is collected after
recovery as described below. All wells are capped and secured prior to leaving the
sampling location.
Decontamination of non-dedicated equipment, using the reagents in Section 6.2.5 of the
QAP, is performed between each sample location, and at the beginning of each sampling
day, in addition to the pre-event decontamination described above.
2.2.2 Sample Collection
Wells
Following the purging of a nitrate investigation well, the sampling takes place once
stabilization has been achieved in accordance with Section 6.2.7 of the QAP. Prior to
leaving the Mill office to sample, a cooler along with ice is prepared. A trip blank is not
required as the sampling event does not include analyses for Volatile Organic
Compounds ("VOCs"). Once Mill Personnel arrive at the well sites, labels are filled out
for the various samples to be collected. All personnel involved with the collection of
water and samples are then outfitted with rubber gloves to avoid sample contamination.
Each sample collection event begins at the location least affected by nitrate (based on the
previous quarter's sampling event) and proceeds by affected concentration to the most
affected location. The dedicated portable pump is appropriately decontaminated prior to
each sampling event, each sampling day, and between well samples. It is important to
note that the rinsate blank sample frequency was modified this quarter as recommended
3
N:lRequired Report,INitr,te Quarterly Monitoring Repnrt120 100412010 04 Nitrate Report text.doc
by UDEQ personnel present on site for split sampling during the chloroform sampling
program. Previously, a rinsate blank sample was collected after each decontamination of
the nondedicated pump and prior to the next use of the pump. Per an e-mail from Mr.
Phil Goble, dated, November 15, 2010, the decreased rinsate blank frequency
implemented during the chloroform sampling program was acceptable for
implementation on the nitrate sampling program. Based on the revised procedure, rinsate
blank samples are only required at the beginning of the sampling event and at the
beginning of each day of sampling. The frequency change was implemented immediately
and the rinsate blank frequency will be modified for all future sampling events.
Samples are taken from the portable pump after stabilization has been achieved, unless
the well is pumped dry. If the well is pumped dry, Mill personnel use a disposable bailer
to sample the well after it has recovered in accordance with Section 6.2.7 of the QAP.
The bailer is attached to a reel of approximately 150 feet of nylon rope and then lowered
into the well. After coming into contact with the water, the bailer is allowed to sink into
the water in order to fill. Once full, the bailer is reeled up out of the well.
Sample bottles are filled as follows;
• First, a 250 ml sample is collected for nitrate/nitrite. This sample is not filtered,
but is preserved with H2S04.
• Second, a 500 ml sample is collected for chloride. This sample is not filtered and
is not chemically preserved.
After the samples have been collected for a particular well, the samples are placed into
the cooler that contains ice. The well is then recapped and Mill personnel proceed to the
next well. If a bailer has been used it is disposed of.
Ponds
Grab samples are taken from the UWLP using a disposable bailer. Sample bottles are
filled in the same manner as for wells, as stated above. After the samples are collected,
the bailer is disposed of and samples are placed into a cooler containing ice for sample
preservation and transit to the Mill's contract analytical laboratory, Energy Laboratories
("EL").
Piezometers
Samples are collected from Piezometers 1, 2 and 3, if possible. Samples are collected
from piezometers using a disposable bailer following the procedures described for wells
that have been pumped dry, above. However, due to the difficulty in obtaining samples
from the piezometers, the purging protocols set out in the QAP are not followed.
After samples are collected, the bailer is disposed of and samples are placed into a cooler
containing ice for sample preservation and transit to the Mill's contract analytical
laboratory, EL.

2.3 Field Data
Attached under Tab B are copies of all Field Data Worksheets that were completed
during the quarter for the nitrate contaminant investigation monitoring wells,
piezometers, and UWLP identified in Section 2.1.1 above, and Table 1. It is important to
note that the field data sheet appearance has changed as a result of the implementation of
an electronic data capture system. The field data sheets contain the same information as
the approved field data sheet attached to the approved QAP in approximately the same
location. The new data sheets allow the electronic capture of data while still maintaining
the real-time recording of information manually in ink as required by UDEQ. The
changes were made to accommodate the data recording and validation system.
2.4 Depth to Groundwater Data and Water Table Contour Map
Depth-to-groundwater measurements which were utilized for groundwater contours are
included on the Quarterly Depth to Water Sheet at Tab C of this Report along with the
kriged groundwater contour map for the current quarter generated from this data. All
well levels used for groundwater contour mapping were measured and recorded within 5
calendar days of each as indicated by the measurement dates in the summary sheet under
Tab C. A copy of the kriged groundwater contour map generated from the previous
quarter of2010 data is provided under Tab D.
2.5 Laboratory Results
2.5.1 Copy of Laboratory Results
All analytical results were provided by EL. Table 1 lists the dates when analytical results
were reported to the Quality Assurance ("QA") Manager for each well or other sample.
Results from analysis of samples collected for the fourth Quarter nitrate investigation are
provided under Tab G of this Report. Also included under Tab G are the results of
analyses for duplicate samples and rinsate samples for this sampling effort, as identified
in Table 1. See the Groundwater Monitoring Report and Chloroform Monitoring Report
for the fourth Quarter of 2010 for nitrate and chloroform analytical results for the
groundwater monitoring wells and chloroform investigation wells not listed in Table 1.
2.5.2 Regulatory Framework
As discussed in Section 1.0 above, the Request, Plan, and Agreement each triggered a
series of actions on DUSA's part. Potential surficial sources of nitrate and chloride have
been described in the December 30, 2009 Contamination Investigation Report. This
quarterly report documents the continued monitoring consistent with the program
described in the Nitrate Contamination Investigation Report.

N:lRequired ReportsINitr.!e Quarterly Morutoring Report120 10 Q41201 0 Q4 Nitr.te Report text.doc
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The Mill QA Manager perfonned a QNQC review to confinn compliance of the
monitoring program with requirements of the QAP. As required in the QAP, data QA
includes preparation and analysis of QC samples in the field, review of field procedures,
an analyte completeness review, and QC review of laboratory data methods and data.
Identification of field QC samples collected and analyzed is provided in Section 3.1.
Discussion of adherence to Mill sampling Standard Operating Procedures ("SOPs") is
provided in Section 3.2. Analytical completeness review results are provided in Section
3.3. The steps and tests applied to check field data QNQC, holding times, receipt
temperature and laboratory data QNQC are discussed in Sections 3.4.1 through 3.4.7
below.
The analytical laboratory has provided summary reports of the analytical QNQC
measurements necessary to maintain confonnance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The Analytical Laboratory QNQC Summary Reports, including copies of the Mill's
Chain of Custody and Analytical Request Record fonns for each set of Analytical
Results, follow the analytical results under Tab G. Results of review of the laboratory
QNQC infonnation are provided under Tab H and discussed in Section 3.4, below.
3.1 Field QC Samples
The following QC samples were generated by Mill personnel and submitted to the
analytical laboratory in order to assess the quality of data resulting from the field
sampling program.
Field QC samples for the nitrate investigation program consist of one field duplicate
sample for each 20 samples, one DI Field Blank ("DIFB") and equipment rinsate
samples.
During the fourth Quarter of 2010, two duplicate samples were collected as indicated in
Table 1. The duplicates were sent blind to the analytical laboratory and analyzed for the
same parameters as the nitrate wells.
Rinsate samples were also collected at the beginning of the sampling period and at the
beginning of each day of sampling from the decontaminated pump used for purging and
sampling. Rinsate samples were labeled with the name of the subsequently sampled well
with a tenninal letter "R" added (e.g. TWN-7R). The results of these analyses are
included with the routine analyses under Tab G.
3.2 Adherence to Mill Sampling SOPs
On a review of adherence by Mill personnel to the existing sampling SOPs, the QA
Manager observed that QNQC requirements established in the QAP were being adhered
to and that the SOPs were implemented, except as described below.
6
N:IRequired Report.INi!r.!e Quarterly Monitoring Report12010 Q412010 Q4 Nitr.te Report text.doc
3.3 Analyte Completeness Review
All analyses required by the GWDP for nitrate monitoring for the period were perfonned.
3.4 Data Validation
The QAP and GWDP (June 17,2010) identify the data validation steps and data QC
checks required for the nitrate monitoring program. Consistent with these requirements,
the QA Manager perfonned the following evaluations: a field data QAlQC Evaluation, a
holding time evaluation, an analytical method check, a reporting limit evaluation, a QC
evaluation of sample duplicates, a QC evaluation of control limits for analysis and
blanks, a receipt temperature evaluation, and a rinsate evaluation. Because no VOCs are
analyzed for the nitrate contamination investigation, no trip blanks are required in the
sampling program. Each evaluation is discussed in the following sections. Data check
tables indicating the results of each test are provided under Tab H.
3.4.1 Field Data QAlQC Evaluation
The QA Manager perfonns a review of all field recorded parameters to assess their
adherence with QAP requirements. The assessment involved review of two sources of
infonnation: the Field Data Sheets and the Quarterly Depth to Water summary sheet.
Review of the Field Data Sheets addresses well purging volumes and stability of five
parameters: conductance, pH, temperature, redox potential, and turbidity. Review of the
Depth to Water data confinns that all depth measurements used for development of
groundwater contour maps were conducted within a five-day period of each other. The
results of this quarter's review are provided under Tab H.
Based upon this review, all well locations confonned to the QAP requirement to evacuate
two well casing volumes before sampling except TWN-3, TWN-7, TWN-14, and TWN-
15. These four wells were all pumped to dryness before two casing volumes were
evacuated. In each case, representative samples of fonnation water were collected after
the wells were allowed to recover. Piezometers 1, 2, and 3 were not pumped, and were
sampled directly after measurement of one set of parameters. Two casing volumes were
pumped from TWN-9, TWN-10 and TWN-17 before they were purged to dryness.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water for the quarterly sampling programs to the nearest
0.01 foot.
All field parameters for all wells were within the QAP required limits, except as follows.
The review of the field sheets for compliance with QAP requirements resulted in the
observations noted below. The QAP requirements in Section 6.2.7 specifically state that
field parameters must have stabilized to within 10% over at least 2 consecutive
measurements. The QAP states that turbidity should be less than 5 Nephelometric
Turbidity Units ("NTU") prior to sampling unless the well is characterized by water that
has a higher turbidity. The QAP does not require that turbidity measurements be less
7
N:lRequired ReportslNilrale Quarterly Monitoring Report12010 0412010 04 Nitrale Report lext.doc
than 5 NTU prior to sampling. As such, the noted observations regarding turbidity
measurements less than 5 NTU below are included for information purposes only.
• Fourteen well measurements and the measurements from Piezometer 3 exceeded
the QAP's 5 NTU turbidity goal as noted in Tab H. In addition, the turbidity
measurements in two wells (TWN-10 and TWN-17) exceeded the QAP's 10%
RPD requirement as noted in Tab H. Both TWN-1 0 and TWN-17 were purged to
dryness before the stabilization of turbidity and as such these wells are not subject
to the QAP stabilization requirement of 10% RPD for turbidity.
DUSA's letter to DRC of March 26,2010 discusses further why turbidity does not appear
to be an appropriate parameter for assessing well stabilization. In response to DRC's
subsequent correspondence dated June 1, 2010 and June 24, 2010, DUSA is currently
implementing a monitoring well redevelopment program. The redevelopment program
has reviewed the available turbidity data for the nitrate wells and has developed a list of
wells that have or will undergo redevelopment utilizing several strategies. The
redevelopment strategies include additional surging and bailing and overpumping as
necessary. Redevelopment is underway, and at the completion of the redevelopment
program, DUSA will review the redevelopment data and summarize the status of the
nitrate wells. Redevelopment results will be discussed with DRC in an effort to come to
a consensus regarding any additional redevelopment steps and/or future turbidity
considerations for the nitrate wells at the Mill site.
The temperature RPD exceeded the QAP specified limit of 10% in TWN-14 because
TWN -14 was pumped dry prior to stabilization of field parameters and as such the QAP
requirement is not applicable.
3.4.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample
holding time checks are provided in Tab H. All samples were received and analyzed
within the required holding time.
3.4.3 Receipt Temperature Evaluation
Chain of Custody sheets were reviewed to confirm compliance with the QAP requirement
in QAP Table 1 that samples be received at 6°C or lower. Sample temperatures checks
are provided in Tab H. All samples were received within the required temperature limit.
3.4.4 Analytical Method Checklist
All analytical methods reported by the laboratory were checked against the required
methods enumerated in the QAP. Analytical method checks are provided in Tab H. All
methods were consistent with the requirements of the QAP.
8
N:\Required Repm1s\Nitrate Quarterly Monitoring Report\2010 Q4\201O Q4 Nitrate Report text.doc
3.4.5 Reporting Limit Evaluation
All analytical method reporting limits reported by the laboratory were checked against
the reporting limits enumerated in the QAP. Reporting Limit Checks are provided in Tab
H. All analytes were measured and reported to the required reporting limits, with the
exception of eleven samples that had increased reporting limits due to matrix interference
or required dilution due to the sample concentration. However, in all of those cases the
analytical results were greater than the reporting limit used.
3.4.6 QAlQC Evaluation for Sample Duplicates
Section 9.1.4 a) of the QAP states that RPDs will be calculated for the comparison of
duplicate and original field samples. The QAP acceptance limits for RPDs between the
duplicate and original field sample is less than or equal to 20% unless the measured
results (described as activities in the QAP) are less than 5 times the required detection
limit. This standard is based on the EPA Contract Laboratory Program National
Functional Guidelines for Inorganic Data Review, February 1994, 9240.1-05-01 as cited
in the QAP. The RPDs are calculated for all duplicate pairs for all analytes regardless of
whether or not the reported concentrations are greater than 5 times the required detection
limits. However, data will be considered noncompliant only when the results are greater
than 5 times the required detection limit and the RPD is greater than 20%. The additional
duplicate information is provided for information purposes.
All analytical results were within the 20% RPD acceptance limits for each of the two
duplicates and its associated well. Results of the RPD test are provided in Tab H.
3.4.7 Rinsate Check
Rinsate checks are provided in Tab H.
Three rinsate blank samples had reported low level concentrations of nitrate. A DIFB
was analyzed and was reported as nondetect for nitrate. A comparison of the rinsate
blank sample concentration levels to the QAP requirements -that rinsate sample
concentrations be one order of magnitude lower than that of the actual well -indicated
that two of the rinsate blank samples met this criterion.
As noted in previous reports, an investigation into the source of the nitrate contamination
present in the rinsate blank samples has been ongoing. Below are the results of the
source investigations, and corrective actions are detailed in Section 5.
The nitrate levels reported in the rinsate blank samples for this investigation are similar to
the nitrate rinsate sample concentrations reported for the previous nitrate sampling
programs and for the chloroform program. Data collected for this ongoing investigation
are as follows:
9
N:IRequired Report.INitrate Quarterly Monitoring Report12010 0412010 Q4 Nitrate Report lext,doc
• The nitrate concentrations in the rinsate samples from both the chloroform
sampling program and the nitrate sampling program are just at or slightly above
the detection limit and are not dependent on or affected by the previous sample
concentrations.
• The presence of nitrate in both the chloroform and nitrate sampling programs
indicates that the contamination is due to external factors such as the nitric acid
rinse during the decontamination process and potential absorption of nitrogen
from the nitric acid into the non-stainless steel portions of the purging equipment
including the pump tubing and connectors.
• Nitrate was detected in a minimum of samples collected for the fourth quarter
2010 nitrate sampling programs.
The investigation into the nitrate in the rinsate blanks is continuing, with additional focus
on the sampling equipment and possible absorption of nitrogen from the nitric acid into
the non-stainless steel portions of the equipment as well as the rinsate collection process.
Nitric acid introduced during the decontamination process is the single highest possible
source of nitrate ions. However, there may be some contribution of nitrate from the
decontamination process and/or the purging equipment. To address these issues, the
decontamination process and rinsate collection process are being reviewed to determine if
the purging equipment in combination with the nitric acid wash used during the
decontamination process are causing the nitrate detections in the rinsate blanks.
Corrective actions are described in Section 5.
3.4.8 Other Laboratory QAlQC
Section 9.2 of the QAP requires that the laboratory's QAlQC Manager check the
following items in developing data reports: (1) sample preparation information is correct
and complete, (2) analysis information is correct and complete, (3) appropriate Analytical
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. In addition to other laboratory checks described above,
DUSA's QA Manager rechecks QC samples and blanks (items (5) and (6)) to confirm
that the percent recovery for spikes and the relative percent difference for spike
duplicates are within the method-specific required limits, or that the case narrative
sufficiently explains any deviation from these limits. Results of this quantitative check
are provided in Tab H. All lab QAlQC results met these requirements.
4.0 INTERPRETATION OF DATA
4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions.
4.1.1 Current Site Groundwater Contour Map
As stated above, a listing of groundwater level readings for the current quarter (shown as
depth to groundwater in feet) is included under Tab C. The data from this tab has been
10
N:lRequired ReportslNitrale Quarterly Monitoring Report12010 Q412010 Q4 Nitrate Report text doc
interpreted (lcriged) and plotted in a water table contour map, provided under the same
tab. The contour map is based on the December 21, 2010 data for all wells.
4.1.2 Comparison of Current Groundwater Contour Map to Groundwater
Contour Map for Previous Quarter
The groundwater contour map for the Mill site for the third quarter of 2010, is attached
under Tab D.
A comparison of the water table contour map for the fourth quarter of 201 0 to the water
table contour map for the previous quarter indicates similar patterns of drawdown related
to pumping of MW-4, MW-26 (TW4-1S), TW4-4, TW4-19 and TW4-20. Water levels
and water level contours for the site have not changed significantly since the last quarter,
except for a few locations. Pumping at TW4-4, which began in the first quarter of 2010,
has depressed the water table near TW4-4, but does not yet appear to have measurably
affected water levels at adjacent wells.
A reported decrease in water level of approximately 7 feet Qppurred in Piez-3. Reported
increases in water levels of approximately 4 feet occurred in well MW-23 , of
approximately 21 feet occurred in well TW 4-18, of approximately S feet occurred in well
TW 4-21, and of approximately 20 feet occurred in well TWN -18. A reported decrease in
water level of approximately 12 feet occurred in pumping well TW4-4, and a reported
increase in water level of approximately 33 feet occurred in pumping well TW4-19.
Water level changes at other pumping wells were less than S feet.
Water level fluctuations at pumping wells MW-4, MW-26 (TW4-1S), TW4-4, TW4-19,
and TW4-20 are due in part to fluctuations in pumping conditions just prior to and at the
time the measurements are taken. The largest decrease (increase in drawdown) of
approximately 12 feet occurred in well TW4-4 and the largest increase (decrease in
drawdown), of approximately 33 feet, occurred at TW4-19. The reported water level at
TW 4-18 appears to be anomalous based on past measurements at the well and results in
an apparent (but localized) groundwater mound in the water level contours. The reported
water level at TWN-18 also appears anomalous based on past measurements and creates
an apparent localized ridge in the water level contours.
4.1.3 Hydrographs
Attached under Tab E are hydro graphs showing groundwater elevation in each nitrate
contaminant investigation monitor well over time.
4.1.4 Depth to Groundwater Measured and Groundwater Elevation
Attached in Tab F are tables showing depth to groundwater measured and groundwater
elevation over time for each of the wells listed in Section 2.1.1 above.

4.2 Review of Analytical Results
4.2.1 Current Nitrate and Chloride Isoconcentration Maps
Included under Tab I of this Report are current nitrate and chloride iso-concentration
maps for the Mill site. Nitrate iso-contours start at 5 mg/L and chloride iso-contours start
at 5 mg/L because those values appear to separate the plumes from background. All
nitrate and chloride data used to develop these iso-concentration maps are from the fourth
quarter 2010 sampling events.
4.2.2 Nitrate and Chloride Concentration Trend Data and Graphs
Attached under Tab J is a table summarizing values for nitrate and chloride for each well
over time. Some data (MW-18, MW-19 and the Frog Pond) were not sampled this period
but the historical data are included for information purposes.
Attached under Tab K are graphs showing nitrate and chloride concentration trends in
each monitor well over time.
4.2.3 Interpretation of Analytical Data
Generally, the shapes of the nitrate and chloride plumes appear to be stable and
unchanged for the last five quarters. The nitrate and chloride plumes maintain their
general geographic association and it is still possible to separate the plumes into a
segment northeast of the wildlife ponds and a southwest segment near the mill site.
Nitrate and chloride concentrations in samples from the downgradient edge of the plumes
(in the vicinity of tailings impoundment monitoring wells MW-30 and MW-31) have
remained essentially unchanged (current concentration within one standard deviation of
the average of the previous four quarters and within laboratory variation) and the plume
does not appear to be migrating in the downgradient direction. In general, both nitrate
and chloride concentrations in nitrate monitoring wells are within 30 percent of values
from last quarter or have declined (Tables 2 and 3).
Notable exceptions include nitrate concentrations in samples from TWN-2 which rose
from near 20 mg/L in the fourth quarter of 2009 to a high of 69 mg/L in the second and
third quarters of2010 (as noted in Table 2 and in Tab K). The concentration of nitrate in
the sample from the fourth quarter of 2010 has fallen to 48 mg/L. A similar, although
less dramatic, pattern can be observed in the chloride data for samples from TWN-2 (as
noted in Table 3 and in Tab K). The concentration of chloride from the fourth quarter
2009 sampling event was 55 mg/L. The chloride concentration rose to a high of 106
mg/L in third quarter 2010 and declined to 93 mg/L in the sample from fourth quarter
2010. Other notable trends include a decline in chloride concentration in samples from
TWN-17 from 152 mg/L in the sample from fourth quarter 2009 to the concentration in
the fourth quarter 2010 of 35 mg/L (as noted in Table 3 and in Tab K). Similarly, the
chloride concentration in Piez-3 declined from 116 mg/L in the sample from first quarter
2010 to 25 mg/L in the sample from fourth quarter 2010. Piez-3 was not sampled in the
fourth quarter of2009 (as noted in Tab K). The current quarter's data continue to support
12
N:lRequired ReportslNitrate Quarterly Monitoring Report120JO 0412010 Q4 Nitrate Report text.doc
the conclusion in the Nitrate Contamination Investigation Report that the nitrate and
chloride are co-extensive and appear to originally come from the same source.
5.0 CORRECTIVE ACTION REPORT
Necessary corrective actions identified during the current monitoring period are described
below.
5.1 Identification and definition of the problem
Nitrate Contamination in Rinsate Blanks
DI water used for decontamination does not show the presence of nitrate. Contamination
does not appear to be related to the nitrate presence in the preceding well that was
purged. Rinsate samples following high concentration wells appear to be the same as
rinsate samples following low concentration wells, rinsate samples following purging of
uncontaminated wells appear to also be contaminated with nitrate. Presence of nitrate in
the rinsate samples is not consistent from one sampling event to the next.
5.2 Assignment of Responsibility for Investigation of the Problem
The problems have been investigated by the QA Manager.
5.3 Investigation and Determination of Cause of the Problem
Rinsate Blank Sample Nitrate Levels
To address the nitrate contamination, DUSA has investigated the potential sources of
nitrate contamination. Nitrile gloves were removed from the rinsate collection process to
eliminate the potential for mobilizing nitrogen compounds present in nitrile gloves
(possibly caused by leaching of nitrogen from the gloves by the nitric acid). In an effort
to address the nitrate contamination, DUSA has reviewed the entire rinsate collection
process and has made additional changes to try and eliminate the source of the nitrate in
the rinsate sample blanks. These additional changes are discussed below.
In addition, DUSA has requested in the revised QAP, submitted June 4, 2010, the
removal of the nitric acid rinse step when samples are not collected for heavy metals,
which will effectively remove the source of nitrate. DUSA will proceed with the removal
ofthat step only upon approval of the QAP revision.
5.4 Determination of a Corrective Action to Eliminate the Problem
Rinsate Blank Sample Nitrate Levels
The nitrate source is most likely the nitric acid rinse used during decontamination
procedures, however, additional conditions which may be contributing to the nitrate
detections in the rinsate blank samples are being investigated. The additional items for
investigation include a contribution from the non-stainless steel purging equipment
13
N:IRequired ReportslNitrate Quarterly Monitoring Report120 10 Q412010 Q4 Nitrate Report text.doc
absorbing nitrate from the nitric acid rinse. To address this potential, all of the non-
stainless steel portions of the purging equipment have been replaced including the pump
tubing and connectors. A single piece of tubing has been placed on the purging pump to
eliminate the absorption or collection of nitric acid by the connectors during the
decontamination process. The tubing is an acid resistant inert material.
5.5 Assigning and Accepting Responsibility for Implementing the Corrective
Action
It will be the responsibility of the Director, Compliance and Permitting to implement the
following corrective actions.
5.6 Implementing the Corrective Action and Evaluating Effectiveness
Rinsate Blank Sample Nitrate Levels
Nitrate sources will be removed after the removal of the nitric acid rinse from the
decontamination procedure when heavy metals are not collected (assuming requisite
changes to the QAP submitted June 4, 2010 are approved by the Executive Secretary).
Additive effects from the decontaminationlrinsate procedure and the contribution from
the non-stainless steel portions of the purging equipment will be evaluated. To eliminate
the potential for contribution made by the non-stainless steel portions of the purging
equipment, the tubing and all other non-stainless steel items have been replaced.
5.7 Verifying That the Corrective Action Has Eliminated the Problem
Nitrate Contamination in Rinsate Blanks
Verification of the contribution from the purging equipment will be completed after the
first quarter 2011 samples have been collected using the new purging equipment and the
data have been reviewed. If nitrate contamination persists then additional sources will be
researched and the investigation will continue. Removal of the nitric acid from the
decontamination procedure will be completed after the Executive Secretary approval of
the June 4,2010 QAP revision is received.
5.8 Assessment of Previous Quarter's Corrective Actions
The third quarter 2010 report identified two corrective actions, which are: turbidity
measurements which exceeded the 10% RPD requirement and nitrate contamination in
the rinsate blanks.
Nitrate contamination in the rinsate blanks is discussed above in Section 5.1.
Turbidity corrective actions are ongoing with the monitoring well redevelopment
program in progress at the Mill. The data collected during the redevelopment program
will be presented to UDEQ under separate cover and discussed to determine the
14
N:lRequired ReportslNitrate Quarterly Monitoring Report12010 0412010 Q4 Nitrate Report text doc
resolution of the turbidity issues discussed in the UDEQ letters dated June 1,2010 and
June 24, 2010.
6.0 CONCLUSIONS AND RECOMMENDATIONS
Generally, the shapes of the nitrate and chloride plumes appear to be stable and
unchanged for the last five quarters. The nitrate and chloride plumes maintain their
general geographic association and it is still possible to separate the plumes into a
segment northeast of the wildlife ponds and a southwest segment near the mill site.
Nitrate and chloride concentrations in samples from the downgradient edge of the plumes
(in the vicinity of tailings impoundment monitoring wells MW-30 and MW-31) have
remained essentially unchanged (current concentration within one standard deviation of
the average of the previous four quarters and within laboratory variation) and the plume
does not appear to be migrating in the downgradient direction. In general, both nitrate
and chloride concentrations in nitrate monitoring wells are within 30 percent of values
from last quarter or have declined (Tables 2 and 3).
The current quarter's data continue to support the conclusion in the Nitrate
Contamination Investigation Report that the nitrate and chloride are co-extensive and
appear to originally come from the same source.
7.0 ELECTRONIC DATA FILES AND FORMAT
DUSA has provided to the Executive Secretary an electronic copy of all laboratory
results for groundwater quality monitoring conducted under the nitrate contaminant
investigation during the Quarter, in Comma Separated Values ("CSV") format. A copy
ofthe transmittal e-mail is included under Tab L.

Sample Delivery Group: C10120464 CASE NARRATIVE
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 tor 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
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results tor 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
