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 mg/L in certain monitoring wells. As a result of the
Request, Denison Mines (USA) Corp. ("DUSA") entered into a Stipulated Consent
Agreement (the "Consent Agreement") with the Utah Water Quality Board in January
2009 which directed the preparation of a Nitrate Contamination Investigation Report
("CIR") 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. The Consent Agreement ("CA") was
amended in August 2011. Under the amended Consent Agreement, DUSA submitted a
Corrective Action Plan ("CAP"), pursuant to the requirements of the Utah Groundwater
Quality Protection Rules [UAC R317-6-6.15(C -E)] on November 29, 2011 and revised
versions of the CAP on February 27,2012 and May 7, 2012.
This is the Quarterly Nitrate Monitoring Report, as required under the Consent
Agreement, State ofUDEQ Docket No. UGW-09-03 for the first quarter of2012.
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 (January through March 2012), are discussed in the
remainder of this section.

with the date samples were collected from each location, and the date( s) upon which
4
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
analytical data were received from the contract laboratory. Table 1 also identifies rinsate
samples collected, as well as sample numbers associated with any required duplicates.
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 this 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 andlor piezometers, pursuant
to Part I.E.3 of the Groundwater Discharge Permit (the "GWDP") (dated July 14,2011):
• The quarterly groundwater compliance monitoring wells.
• Existing well MW -4 and all of the temporary chloroform investigation wells.
• Piezometers -P-1, P-2, P-3, P-4 and P-S.
• MW-20, MW-22, and MW-34.
• The DR piezometers which were installed during the Southwest Hydrogeologic
Investigation.
• 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 of the sampling purpose.
All well levels used for groundwater contour mapping were measured and recorded
within S 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
S
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
The QAP provides a detailed presentation of procedures utilized for groundwater
sampling activities under the GWDP (July 14,2011).
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 are decontaminated using the cleaning
agents described in Section 6.2.5 of the QAP. A rinsate blank is collected after the first
pump decontamination of each day as described below. 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 measured 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 for sampling, Mill Personnel prepare a cooler with ice. 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.
6
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
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 during the fourth quarter 2010
as recommended 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 during
fourth quarter 2010. The rinsate blank sample frequency will be modified again during
the third quarter 2012 sampling event pursuant to UDEQ approval of the Groundwater
QAP, Revision 7.1 on May 30, 2012. The frequency for rinsate blank samples will be
one rinsate blank sample for every 20 field samples.
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").
7
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
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 was changed in the fourth quarter 2010 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. Revised field forms will be used during the third quarter 2012
sampling event. The revised field forms are based on the changes approved in the
Groundwater QAP, Revision 7.1. Approval of the QAP, Revision 7.1 was received May
30, 2012.
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's 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 this quarter's 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
8
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
for this quarter 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 Consent 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 CIR and additional investigations
into potential sources were completed. Pursuant to the Consent Agreement, the most
recent version of the CAP was submitted to the Co-Executive Secretary on May 7, 2012.
The CAP will describe future activities associated with the nitrate in groundwater. This
quarterly report documents the continued monitoring consistent with the program
described in the initial Nitrate Contamination Investigation Report submitted in 2009.
The monitoring program and reporting requirements set forth in the 2009 Contamination
Investigation report will remain in effect until further notice and completion of the CAP.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The Mill QA Manager performed a QAIQC review to confirm 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 QAlQC, holding times, receipt
temperature and laboratory data QAlQC are discussed in Sections 3.4.1 through 3.4.7
below.
The analytical laboratory has provided summary reports of the analytical QAlQC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The Analytical Laboratory QAIQC Summary Reports, including copies of the Mill's
Chain of Custody and Analytical Request Record forms for each set of Analytical
Results, follow the analytical results under Tab G. Results of review of the laboratory
QAIQC information 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.
9
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
During the quarter, 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 terminal letter "R" added (e.g. TWN-7R). During the quarter three rinsate samples
were collected and were sent to the analytical laboratory and analyzed for the same
parameters as the nitrate wells. 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 QAlQC requirements established in the QAP were being adhered
to and that the SOPs were implemented, except as noted below.
3.3 Analyte Completeness Review
All analyses required by the GWDP for nitrate monitoring for the period were performed.
3.4 Data Validation
The QAP and GWDP (July 14, 2011) identify the data validation steps and data QC
checks required for the nitrate monitoring program. Consistent with these requirements,
the QA Manager performed 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 QAJQC Evaluation
The QA Manager performs a review of all field recorded parameters to assess their
adherence with QAP requirements. The assessment involved review of two sources of
information: 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 confirms 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.
10
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 Ql\2012 Ql Nitrate Report text.docx
Based upon this review, all well locations conformed to the QAP requirement to evacuate
two well casing volumes before sampling except TWN-2, TWN-3, TWN-7, TWN-9,
TWN-14, TWN-15, and TWN-17. These seven wells were all pumped to dryness before
two casing volumes were evacuated and more than one set of field parameters could be
collected. In each case, representative samples of formation 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-I0 before it was purged to dryness; however, only one set of field
parameters were collected prior to TWN -10 being pumped dry.
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, as indicated
below.
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 must be
less 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.
• Fifteen well measurements and the measurements from Piezometers 2 and 3
exceeded the QAP's 5 NTU turbidity goal as noted in Tab H. All turbidity RPD's
met the QAP Requirement to stabilize within 10%.
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 has completed
a monitoring well redevelopment program. The redevelopment report was submitted to
DRC on September 30, 2011. Redevelopment results will be discussed with DRC in an
effort to come to a consensus regarding turbidity considerations for the nitrate wells at the
Mill site.
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
11
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
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.
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 9 samples (8 samples and 1 duplicate) 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 duplicate results were within a 20% RPD. Results of the RPD test are provided in Tab
H.
3.4.7 Rinsate Check
Rinsate checks are provided in Tab H. A review of the analytical results reported for
rinsate samples indicated that one of the rinsate samples had a low level detection of
nitrate at 0.2 mg/L nitrate.
A comparison of the rinsate 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 the rinsate sample had concentrations of nitrate above this
conformance level.

The nitrate concentration in the rinsate sample is just slightly above the detection limit
and is not dependent on or affected by the previous sample concentrations. This indicates
that the contamination is due to some external factor such as the nitric acid rinse during
the decontamination process rather than cross-contamination from the purging process.
However, based on the above findings, for this current quarter's data, the presence of
nitrate in the rinsate sample does not affect the validity or utility of the groundwater data
for the following reasons:
• F or the one well in which the preceding rinsate sample levels exceeded the
conformance criterion, the nitrate concentrations in the well and the rinsate
samples were significantly lower than the GWDP GWCL of 10.0 mg/L for nitrate.
• Low level rinsate samples are indicative of potential false positive results in the
low level sample results. Higher level sample results could potentially be biased
high. Both situations are a more conservative approach to the assessment of
sample results because a high bias means that reported results for this analyte will
tend to be more conservative or higher than actual concentrations.
Complete assessment of the nitrate detections in the rinsate samples cannot be completed
until the nitric acid rinse is removed from the decontamination process. To address the
likely nitric acid contamination, DUSA has submitted a revised QAP (Revision 7.1) in
which the nitric acid rinse step has been removed from the decontamination procedure
when samples are not collected for heavy metals. UDEQ provided approval of QAP,
Revision 7.1 on May 30, 2012. DUSA will remove the nitric acid step from the
decontamination procedure and has initiated the assessment of the effect of this removal
as of May 31,2012.
If nitrate is detected in rinsate samples after the removal of the nitric acid wash from the
decontamination procedure an investigation into the possible causes will be completed
including but not limited to review of the laboratory procedures, split analysis of rinsate
samples, and an investigation into the DI system. It is important to note that an
appropriate DI system has been identified. Installation is scheduled to follow construction
of other capital improvements in the Mill in late 2012 or early 2013.
Corrective actions for this issue are described in Section 5.1.
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: (l) 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
13
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
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 specified acceptance limits except as noted below.
The QAP Section 8.1.2 requires that an MS/MSD (referred to as Duplicate Spike [Matrix
spike] in the QAP) pair be analyzed with each analytical batch. The QAP does not
specify acceptance limits for the MS/MSD pair, and the QAP does not specify that the
MS/MSD pair be prepared on DUSA samples only. Acceptance limits for MS/MSDs are
set by the laboratories. The review of the information provided by the laboratories in the
data packages verified that the QAP requirement to analyze an MS/MSD pair with each
analytical batch was met. While the QAP does not require it, the recoveries were
reviewed for compliance with the laboratory established acceptance limits. The QAP
does not require this level of review, and the results of this review are provided for
information only.
The information from the Laboratory QAlQC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all quarterly nitrate samples are within
acceptable laboratory limits for all regulated compounds as indicated in Tab H. The QAP
requirement to analyze a MS/MSD pair with each analytical batch was met and as such
the data are compliant with the QAP.
The information from the Laboratory QAIQC Summary Reports indicates that the LCS
recovenes were acceptable which indicate that the analytical system was operating
properly.
The QAP Section 8.1.2 requires that each analytical batch shall be accompanied by a
reagent blank. All analytical batches routinely contain a blank, which is a blank sample
made and carried through all analytical steps. F or the Mill samples, a method blank is
prepared for all analytical methods. The information from the Laboratory QAlQC
Summary Reports indicates that the method blanks did not contain detections of any
target analytes above the RL.
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
interpreted (kriged) and plotted in a water table contour map, provided under the same
tab. The contour map is based on the current quarter's data for all wells.
14
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
4.1.2 Comparison of Current Groundwater Contour Map to Groundwater
Contour Map for Previous Quarter
The groundwater contour maps for the Mill site for the previous quarter, as submitted
with the Nitrate Monitoring Report for the previous quarter, are attached under Tab D.
A comparison of the water table contour maps for the current (first) quarter of2012 to the
water table contour maps for the previous quarter (fourth quarter of 2011) indicates
similar patterns of drawdown related to pumping of MW -4, MW -26, TW 4-4, TW 4-19
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. As discussed in Section
4.1.1, pumping at TW4-4, which began in the first quarter of 2010, has depressed the
water table near TW4-4, but a well-defined cone of depression is not yet evident, likely
due to variable permeability conditions near TW 4-4 and the low water level at adjacent
well TW4-14.
Reported increases in water levels of approximately 7 feet occurred in recently installed
well TW4-27 and of approximately 5 feet occurred in well MW-37. Reported increases in
water levels of approximately 9 feet occurred in pumping well TW 4-20 and of
approximately 8 feet occurred in pumping well MW-26. The water level changes at
pumping wells MW-4, TW4-4, and TW4-19 were less than 5 feet.
Water level fluctuations at pumping wells MW-4, MW-26, 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 1
foot occurred in well TW 4-4 and the largest increase (decrease in drawdown), of
approximately 9 feet, occurred in well TW4-20. The reported water level at well MW-37
during the current quarter is similar to the reported third quarter, 2011 water level, and
the water level at TW4-27 is similar to that reported at the time of installation. Reported
water levels at both wells in the previous quarter were lower than typical. The decrease
in water level in TW4-27 in the fourth quarter of 2011 is due to the fact that the water
level in that well was measured immediately following development activities prior to
complete stabilization of the water level in the well.

contaminant investigation monitor well over time.
4.1.4 Depth to Groundwater Measured and Groundwater Elevation

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 100 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
current quarter's 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 plots 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 nine 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 at 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 eight quarters and within laboratory variation) and the plume does not
appear to be migrating in the downgradient direction.
In general, nitrate concentrations in nitrate monitoring wells are similar to values from
last quarter or have declined (Table 2). The nitrate concentration measured in TWN-10 of
0.8 mg/L is 300% higher than the 0.2 mg/L measured last quarter but lower than the 1.5
mg/L concentration that has previously been measured in samples from this well. Some
chloride concentrations are up slightly from last quarter but, with one exception, are
within the range of previously measured concentrations. The measured chloride
concentration in PIEZ-1 of 78 mg/L is higher than the previous high of 60 mg/L (Table
3). The current quarter's data continue to support the conclusion in the Nitrate
Contamination Investigation Report that the nitrate and chloride at the Mill site are co-
extensive and appear to originally come from the same source.
Note that samples from recently installed chloroform monitoring wells TW 4-26 and
TW 4-27 had measured nitrate concentrations that are higher than 10 mg/L. However,
nitrate concentrations in these wells are clearly separated from the nitrate/chloride plume
at the Mill site by many wells that are below 10 mg/L or are nondetect for nitrate,
16
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
including but not limited to, TW4-23, MW-32 and TW4-16. Thus, nitrate in TW4-26 and
TW4-27 appears to be isolated from the plume at the Mill site, in the same way that the
relatively small nitrate plumes at TWN-09 and TWN-17 are isolated from the plume at
the Mill site.
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
Rinsate Nitrate Levels
One rinsate sample has nitrate levels that most likely result from decontamination
procedures.
5.2 Assignment of Responsibility for Investigation of the Problem
The problem has been investigated by the QA Manager.
5.3 Investigation and Determination of Cause of the Problem
To address the nitric acid contamination, DUSA requested in the revised QAP the
removal of the nitric acid rinse step when samples are not collected for heavy metals.
DUSA received approval of the revised QAP on May 30, 2012.
5.4 Determination of a Corrective Action to Eliminate the Problem
The corrective action is the removal of the nitric acid rinse from the decontamination
procedures when samples are not collected for heavy metals.
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 action.
The corrective action is the removal of the nitric acid rinse from the decontamination
procedures when samples are not collected for heavy metals.
5.6 Implementing the Corrective Action and Evaluating Effectiveness
Removal of the nitric acid rinse from the decontamination procedure has been
implemented as of May 31, 2012.
5. 7 Verifying That the Corrective Action Has Eliminated the Problem
17
N:\Required Reports\Nitrate Quarterly Monitoring Report\2012 QI\2012 QI Nitrate Report text.docx
Verification that nitrate source(s) have been removed is underway. DUSA is currently
evaluating whether the removal of the nitric acid rinse from the decontamination
procedure has effectively removed the nitrate source in the rinsate blank samples.
5.8 Assessment of Previous Quarter's Corrective Actions
Chloride was present in the rinsate blanks and in the DIFB for the fourth quarter 2011.
To address previous nitrate contamination in the nitrate and chloroform sampling
programs, an additional rinse with 55-gallons of DI water has previously been added to
the decontamination process. DUSA believes that the source for the chloride present in
the rinsate blanks in the fourth quarter appears to be related to the increasing volume of
DI water used in the rinsate process due to the second 55-gallon rinse of the portable
pump with DI water. The chloride present in the rinsate blanks is present in the DI water
and is not the result of inadequate decontamination of the purging pump. The chloride
contamination in the DI water is most likely the result of chlorination of the intake water
(from the potable water supply source) used for the DI system. At high volume use rates,
the DI system appears to be unable to remove all of the chloride introduced with the DI
intake (supply) water.
To address the issue, the QA Manager and the mill staff have identified an appropriate DI
system. Installation is scheduled to follow construction of other capital improvements in
the Mill in late 2012 or early 2013.
Verification that chloride contamination has been eliminated will occur upon completion
of the system upgrades and receipt of at least the two quarters of data. If chloride
contamination persists then additional sources will be researched and the investigation
will continue.
6.0 CONCLUSIONS AND RECOMMENDATIONS
Generally, the shapes of the nitrate and chloride plumes appear to be stable and
unchanged for the last nine 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 at 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 eight quarters and within laboratory variation) and the plume
does not appear to be migrating in the downgradient direction.
The current quarter's data continue to support the conclusion in the Nitrate
Contamination Investigation Report that the nitrate and chloride at the Mill site are co-
extensive and appear to originally come from the same source.

Sample Delivery Group: C12010435
REVISED/SUPPLEMENTAL REPORT
Revised Date: 04/09/12
Report Date: 01/23/12
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
April 9, 2012 for the correction of the collection time on sample TWN-65.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
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.
SOIL/SOLID 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 for all seven are ND (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.
