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, reconunended that DUSA also address elevated chloride
concentration in the Nitrate Monitoring Reports.
The CIR was submitted to the Co-Executive Secretary of the Utah Water Quality Board
(the "Co-Executive Secretary") on December 30, 2009. By a letter dated October 5,
2010, the Co-Executive Secretary notified DUSA of his determination that the CIR is
incomplete. As a result of that letter, additional negotiations with UDEQ have been
completed, and DUSA agreed to submit to the Co-Executive Secretary for approval a
plan and schedule to perform further investigations in order to remedy deficiencies.
DUSA and UDEQ entered into a Tolling agreement on November 30, 2011, revised on
April 28, 2011, to allow time to perform a multi-phased field investigation, evaluate a
number of potential Mill-related and non-Mill sources, and to revise and update the CIR.
Based on agreements between UDEQ and DUSA, the Tolling Agreement was revised
and finalized on June 30, 2011, to allow sufficient time for preparation and UDEQ
approval of work plans and milestones dates for the remainder of the investigations.
This is the Quarterly Nitrate Monitoring Report, as required under the Consent
Agreement, State of UDEQ Docket No. UGW -09-03 for the second Quarter of 2011 (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 (April through June 2011), are discussed in the remainder of
this section.

Table 1 provides an overview of all locations sampled during the current period, along
with the date samples were collected from each location, and the date(s) upon which
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 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 I.E.3 of the Groundwater Discharge Permit (the "GWDP") (February 15, 2011):
• The quarterly groundwater compliance monitoring wells.
2
N:lRcquircd Repon.lNilrale Quarterly Moniloring Reportl20 II Q212011 Q2 Nilrale Report leXl.doe
• Existing well MW-4 and all of the temporary chloroform investigation wells.
• Piezometers -P-l, P-2, P-3, P-4 and P-5.
• MW-20, MW-22, and MW-34
• 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 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 (February 15,2011).
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 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.
3
N:lRcquired RepOiISINilrate Quarterly Monitoring Reponl20 II Q2120 II Q2 Nitrate Repun text.doc
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 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 fromMr.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.
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.
4
N:IRequircd ReporlslNilrale Quarterly Moniloring Rcport12011 Q2120 II Q2 Nitrale Report lexLdoe
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 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.
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 the second 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 second Quarter of 2011 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 Agreements 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 and
additional investigations into potential sources have been on going since second quarter
2011. 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 additional studies described in the plans submitted to UDEQ are
complete and subsequent negotiations with UDEQ are complete.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The Mill QA Manager performed a QAJQC 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 QAJQC, holding times, receipt
temperature and laboratory data QAJQC are discussed in Sections 3.4.1 through 3.4.7
below.
The analytical laboratory has provided summary reports of the analytical QAJQC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The Analytical Laboratory QAJQC 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
QAJQC information are provided under Tab H and discussed in Section 3.4, below.

N:IRequired RcporlslNilralC Quarterly Monitoring Reportl2011 Q2120 II Q2 Nilrale Report leXl.doc
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 ("DlFB") and equipment rinsate
samples.
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). 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 (February 15, 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 QAlQC 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
7
N:IRequired Repo((slNilrale Quarterly Monilocing Rcportl2011 Q212011 Q2 Nilrale Report Icxl.doc
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.
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-lO, TWN-14, TWN-15, TWN-17, and TWN-19. These nine wells were all
pumped to dryness before two casing volumes were evacuated. 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-10
before it was 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, 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 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.
• Seventeen well measurements and the measurements from UWLP, Piezometers 1,
2, and 3 exceeded the QAP's 5 NTU turbidity goal as noted in Tab H. In addition,
the turbidity measurements in four wells (TWN-7, TWN-9, TWN-lO, and TWN-
19) exceeded the QAP's 10% RPD requirement as noted in Tab H. All four wells
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. Additionally, five wells were purged to dryness before more than one
set of field parameters could be collected.
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 undergone redevelopment utilizing several strategies. The redevelopment
8
N:IRcquircd RcportsINilralc Quarterly Monitoring Rcportl20 II Q2120 II Q2 Nitrate Report lexLdoc
strategies include additional surging and bailing and overpumping as necessary. Surging
and bailing and overpumping for the nitrate, groundwater, and chloroform wells is
complete. Data from the redevelopment of the nitrate wells will be reviewed with the
data from the redevelopment of the chloroform and groundwater programs. A single
report will be prepared at the completion of the redevelopment program for the wells in
all three programs which is planned for submittal on or before the end of the third quarter
2011. DUSA will review the redevelopment data and summarize the status of the Mill
wells. 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.
The conductivity RPD exceeded the QAP specified limit of 10% in TWN-9 because
TWN-9 was pumped dry prior to stabilization of field parameters and as such the QAP
requirement is not applicable. Additionally, the pH RPD in TWN-7 and TWN-lO and the
Redox RPD in TWN-lO exceeded the QAP specified limit of 10%. Both TWN-7 and
TWN-lO were pumped dry prior to stabilization of field parameters, so as noted above,
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.
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 eight samples and one duplicate sample 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.
Of the four rinsate blanks collected, one rinsate blank sample reported concentrations of
nitrate. A DIFB was analyzed and was reported as non detect 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 the one rinsate blank sample with a detection of nitrate met this criterion.
Corrective action for the rinsate blank detections is discussed below and in Section 5.
As noted in previous reports, low level detections of nitrate in the rinsate blanks have
been reported in both the nitrate sampling program and the chloroform sampling
program. In addition, increased nitrate concentrations in the nitrate program rinsate
blanks were noted in the first quarter 2011. An investigation into the increased nitrate
concentrations in the first quarter of 2011 by the QA Manager was completed. The
investigation results showed that Field Staff were reusing the decontamination soap and
nitric acid decontamination fluids for more than the one day currently permitted per a
UDEQ November 15, 2010 e-mail. The corrective actions implemented during the first
quarter 2011 yielded a decrease in nitrate contamination in second quarter 2011, but did
not eliminate the issue entirely. To further address the low level nitrate detections in the
second quarter of 2011, changes were made to the rinsate collection process during the
second quarter chloroform program conducted in May 2011
Corrective actions delineating the changes in the rinsate process are described in Section
5. Assessment of the effectiveness of the corrective actions for the rinsate blank issues
from the first quarter 2011 are also discussed 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 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 except as indicated in Tab H.
The recoveries, which are above the laboratory established acceptance limits, do not
affect the quality or usability of the data because the recoveries above the acceptance
limits are indicative of matrix interference. 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.
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
11
N:\Requu-ed ReportsINitratc Quarterly Monitoring Repon\2011 Q2\2011 Q2 Nitrate Repon texl.doc
interpreted (kriged) and plotted in a water table contour map, provided under the same
tab. The contour map is based on the June 21,2011 data for all wells.
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 first quarter of 2011, as submitted
with the first quarter of 2011 report are attached under Tab D.
A comparison of the water table contour maps for the second quarter of 2011 to the water
table contour maps for the previous quarter (first quarter of 2011) indicates similar
patterns of drawdown related to pumping of MW -4, MW -26, TW 4-4, TW 4-19 and TW 4-
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 TW 4-4, which began in the first quarter of 2010, has depressed the water table near
TW4-4, but does not yet appear to have affected water levels at adjacent wells
sufficiently for a well-defined cone of depression to be evident.
Reported increases in water levels of approximately 5 feet occurred in MW-18, of
approximately 7 feet occurred in both MW-35 and TW4-3, and of approximately 5 feet
occurred in TW4-21. The apparent increase in water level at MW-35 this quarter was due
to use of a surveyed rather than estimated casing elevation. A reported decrease in water
level of approximately 5 feet occurred in well MW -20. Low water levels in MW -20 are
potentially the result of the recent surging and bailing activities. Reported increases in
water levels of nearly 11 feet occurred in pumping well MW-4, of approximately 20 feet
occurred in pumping well TW4-19, and of approximately 16 feet occurred in pumping
well TW4-20. A reported decrease in water level of approximately 9 feet occurred in
pumping well MW-26. The water level change at the remaining pumping well (TW4-4)
was less than 1 foot.
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 9
feet occurred in well MW-26 and the largest increase (decrease in drawdown), of
approximately 20 feet, occurred at TW4-19. The water level reported for MW-18 during
the current quarter is more similar to historical measurements than that reported for the
previous quarter.
4.1.3 Hydrographs
Attached under Tab E are hydro graphs showing groundwater elevation in each nitrate
contaminant investigation monitor well over time.

N:IRequircd ReportslNitrate Quarterly Monitoring Reportl20J I Q212011 Q2 Nitrate Report text.doc
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
second quarter 2011 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 seven 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 six quarters and within laboratory variation) and the plume
does not appear to be migrating in the down gradient direction. In general, both nitrate
and chloride concentrations in nitrate monitoring wells are similar to values from last
quarter or have declined (Tables 2 and 3).
A notable exception is the nitrate concentration in samples from TWN-lO which rose
from 0.3 mg/L in the first quarter of 2011 to 1.2 mg/L in the second quarter of 2011 (as
noted in Table 2 and in Tab K). The range of concentrations of nitrate in samples from
this well during the last seven quarters is 0.2 to 1.5 mg/L (Table 2). The increase in
concentration noted above occurred in a well that is upgradient of Mill activities. 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.

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
During this reporting period the nitrate levels in the rinsate blanks, after having
significantly decreased since last quarter, were still present.
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 Nit)" te Levels Still Present
Upon review of the data, it was noted by the QA manager that nitrate contamination in
the rinsate blanks was still present. However, it is important to note that the low level
nitrate detection in the rinsate blanks is not having an impact on the well samples. An
ongoing investigation to determine the potential sources of nitrate contamination
continued in second quarter 2011. Denison believes that the nitric acid used during the
decontamination procedure is the source of nitrate contamination noted in the rinsate
blanks. Small amounts of nitric acid are being moved from decontamination vessel to
decontamination vessel and cross-contaminating the rinsate blanks.
5.4 Determination of a Corrective Action to Eliminate the Problem
Rinsate Blank Sample Nitrate Levels
A second Dr water rinse was added to the decontamination process to eliminate the low
level nitrate contamination. Addition of the second Dr rinse was implemented for the
chloroform program in the second quarter 2011. The results were successful in
eliminating the nitrate contamination. This addition to the rinsate process will be
implemented in the nitrate program during the third quarter sampling event.
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.
14
N:lRequired Report,lNilrale Quarterly Monitoring Reponl2011 Q212011 Q2 Nitrate RepOl1texl.doc
5.6 Implementing the Corrective Action and Evaluating Effectiveness
Rinsate Blank Sample Nitrate Levels
The low level detections of nitrate in the rinsate blanks will be removed after the addition
of a second Dr water rinse to the process. The corrected procedure will be implemented
during the third quarter nitrate sampling event.
5.7 Verifying That the Corrective Action Has Eliminated the Problem
Nitrate Contamination in Rinsate Blanks
Verification of the corrected procedure was implementation for the second quarter
chloroform sampling. The corrected procedure eliminated the nitrate contamination in
the rinsate blanks. The same procedure will be used in the third quarter nitrate sampling
event. The third quarter 2011 data will be used to determine if additional investigations
into the low level contamination are needed.
5.S Assessment of Previous Quarter's Corrective Actions
The first quarter 2011 report identified a corrective action for increased nitrate
contamination in the rinsate blanks.
An investigation into the rising concentrations in the first quarter of 2011 by the QA
Manager was completed. The investigation results showed that Field Staff were reusing
the decontamination soap and nitric acid decontamination fluids for more than the one
day currently permitted per a UDEQ November 15,2010 e-mail. The results are noted in
the rising concentrations on consecutive days that rinsate blanks were collected. The
decontamination procedure was discussed with Field Personnel. Field Personnel were
reminded that decontamination fluids could be reused for only one day before disposal.
Verification of the corrected procedure implementation was conducted in April 2011.
The verification was completed by the QA Manager during a visit to the Mill. The QA
Manager observed decontamination procedures during the second quarter 2011 event.
No further corrective actions are necessary regarding the decontamination procedures.
6.0 CONCLUSIONS AND RECOMMENDATIONS
Generally, the shapes of the nitrate and chloride plumes appear to be stable and
unchanged for the last seven 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 six quarters and within laboratory variation) and the plume
15
N:lRequired ReportslNilrale QuaJ1erly Monitoring Reportl201 L Q212011 Q2 Nitrate Report text.doc
doe not appear to be mjgrating in the downgradient direction. In general both citrate
and chloride concentration in nitrate monitoring well ' are imilar to value from la l
quarter or have declined (Table 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.

Comments: all depths were checked on 6/21/11 with the exeption of the DR series wells, they were
checked on 6/22/11. we don't have logged depths on the DR series as of yet. We obtained the MW-36
and MW-37 logged depths as a special request. We still do not have a tagged depth on the MW series
of wells as they all have dedicated pumps in the wells and we do not want to distrub the column.
Time was not recorded on the DR series wells. 1m not sure why, but moving forward we will ensure
that the time is recorded on these wells.

CLIENT: Denison Mines USA Corp
Project: 2nd Quarter Nitrate 2011 Report Date: 05/03/11
Sample Delivery Group: C11040728 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(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 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 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.

CLIENT: Denison Mines USA Corp
Project: 2nd Quarter Nitrate 2011
Sample Delivery Group: C11040896
ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Report Date: OS/20/11
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
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.
