1.0 INTRODUCTION
This is the Routine Groundwater Monitoring Report, as required under Part 1.F.1 of State
of Utah Groundwater Discharge Permit No. UGW370004 (the "GWDP") for the third
quarter of 2011 (the "quarter") for Denison Mines (USA) Corp's. ("DUSA's") White
Mesa Uranium Mill (the "Mill"). As required under Parts 1.E.1, 1.E.2 and I.E.5 of the
GWDP this Report includes all recorded field measurements and laboratory analyses for
well monitoring conducted during the quarter.
1.1 GWDP Modifications During the Third Quarter
During the third quarter of 2011, the approved February 15, 2011 GWDP was revised on
July 14, 2011. The revision incorporated changes necessary to address various activities
at the Mill. No changes were issued to the Groundwater Compliance Limits ("GWCLs")
specified in Table 2 or to the groundwater monitoring program described herein.
2.0 GROUNDWATER MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, chloroform contaminant investigation wells and nitrate contaminant investigation
wells is attached under Tab A. Groundwater samples and measurements were taken
during this reporting period (January through March), as discussed in the remainder of
this section.
2.1.1 Groundwater Compliance Monitoring
Groundwater samples and field measurements collected during the third quarter included
both quarterly and accelerated monitoring. Accelerated monitoring is discussed below in
Section 2.1.2. In this third quarter report, samples classified as being collected quarterly
include those wells which are routinely sampled every quarter as well as semi-annual
wells which are sampled on an accelerated quarterly schedule due to exceedances
reported in previous quarterly reports. Wells which are sampled routinely every quarter
were analyzed for the parameters listed in Table 2 and Part 1.E.1.c) 2)ii of the GWDP
dated February 15, 2011 and July 14, 2011. The semi-annual wells which have been
accelerated to quarterly are analyzed only for those parameters which exceeded the
GWCLs in Table 2 and Part I.E.1.c) 2)ii of the GWDP as described in the 2nd Quarter
Groundwater Monitoring Report (DUSA August 31, 2011).
Table 1 of this report provides an overview of all wells sampled during the current
period, along with the required sampling frequency applicable to each well during the
current monitoring period, the date samples were collected from each well, and the
date(s) analytical data were received from the contract laboratory(ies). Table 1 also
indicates which sample numbers are associated with the required duplicates. During this
1
N:lRequired Report.\Groundwater Quarterly Monitoring Report\2011 Q3\3,d Qtr 20 11 GW.doc
quarter, five wells and one duplicate were resampled due to preservation (pH) outside of
acceptance limits when the samples were received at the laboratory. In addition one well
and the duplicate were resampled because the laboratory inadvertently lost the thallium
sample aliquot for the duplicate sample (MW -70). The sample and its duplicate were
resampled for thallium. The following is a list of wells which were resampled:
• MW -14 was resampled for metals, nitrate, ammonia, and Gross Alpha minus
Rn222 and Uranium ("gross alpha") due to preservation issues.
• MW-18/MW-70 were resampled for thallium because the laboratory lost the
thallium aliquot for MW -70.
• MW-25, MW-26, MW-32, MW-35, and MW-65 (duplicate of MW-26) were
resampled for metals and gross alpha due to preservation issues.
2.1.2 Accelerated Groundwater Monitoring.
In addition to the quarterly monitoring referenced above, accelerated monthly sampling
was performed, and results reported, for the wells indicated in Table 1. The accelerated
sampling frequency, analyte list and well list were determined based on the previously
reported analytical results and are included in Table 2 of this report.
Table 1 provides an overview of the wells sampled for the accelerated monthly program
along with the routine sampling frequency as well as the accelerated sampling frequency,
the date samples were collected from each well, the associated duplicates and the date(s)
which analytical data were received from the contract laboratory(ies).
2.1.3 Background Well Monitoring
A requirement was added to the GWDP on February 15, 2011, which required the Mill to
begin quarterly sampling of wells MW-35, MW-36 and MW-37 to develop eight quarters
of background data. MW-35, which was installed in the third quarter 2010, has been
sampled quarterly since fourth quarter 2010. MW-36 and MW-37, which were installed
during the second quarter 2011, were sampled for the first time this quarter. Quarterly
samples will continue to be collected until 8 quarters of data are available to complete the
background report as required by the GWDP.
2.1.4 Parameters Analyzed
All routine quarterly groundwater monitoring samples were analyzed for the parameters
listed in Table 2 and Part I.E.1.c) 2)ii of the GWDP dated February 15,2010 and July 14,
2011. The accelerated monitoring samples were analyzed for a more limited and specific
parameter list as shown in Table 2 of this report.

2.1.5 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant
to Part I.E.2 of the GWDP dated February 15, 2011and July 14,2011:
• The groundwater compliance monitoring wells including MW-20, MW-22, MW-
34, MW-3S, MW-36 and MW-37.
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-1, P-2, P-3, P-4 and P-S.
• 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 water 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 D.
2.2 Field Data
Attached under Tab B are copies of all field data sheets recorded in association with the
quarterly effort for the groundwater compliance monitoring wells referred to in paragraph
2.1.1, above. Sampling dates are listed in Table 1.
Attached under Tab C are copies of all field data sheets recorded in association with the
July and September 2011 accelerated monitoring and sampling efforts.
2.3 Laboratory Results -Quarterly Sampling
2.3.1 Copy of Laboratory Results

Tab E are the results of analyses for duplicate samples for this sampling effort, as
identified in Table 1.
The laboratory report dates for samples collected for the July and September accelerated
sampling (i.e. quarterly accelerated to monthly) are provided in Table 1. Results from
analysis of samples collected for the July and September accelerated sampling (i.e.
quarterly accelerated to monthly) are provided in Tab F. Also included under Tab Fare
the results of analyses for duplicate samples for this sampling effort, as identified in
Table 1.
Copies of laboratory QNQuality Control ("QC") Summaries are included with the
reported data under their corresponding Tabs.
2.3.2 Regulatory Framework and Groundwater Background
Under the GWDP (February 15, 2011 and July 14, 2011), background groundwater
quality has been determined on a well-by-well basis, as defined by the mean plus second
standard deviation concentration or the equivalent. New GWCLs that reflect this
background groundwater quality have been set for all monitoring wells in the January 20,
2010 GWDP. These new GWCLs were in effect for sampling required during the current
third quarter monitoring period.
Exceedances of the January 21,2010 GWCLs as reported in 2010 reports determined the
accelerated monthly monitoring program implemented during this quarter.
Exceedances of the GWCLs for the third quarter (July through September) of 2011 are
listed in Table 2 for sampling required under the revised GWDP (February 15,2011 and
July 14). Table 3 shows the accelerated sampling program which started in the second
quarter 2010 and shows the results and frequency of the accelerated sampling conducted
since that time.
It should be noted, however, that, because the GWCLs have been set at the mean plus
second standard deviation, or the equivalent, un-impacted groundwater would normally
be expected to exceed the GWCLs approximately 2.5% of the time. Therefore,
exceedances are expected in approximately 2.5% of all sample results, and do not
necessarily represent impacts to groundwater from Mill operations.
2.4 laboratory Results -Accelerated Monitoring
2.4.1 Copy of Laboratory Results
The analytical results for the accelerated monthly monitoring of the various constituents
in certain monitoring wells for the quarter are provided at Tab F.

N:IRequired RcporlslGroundwale,.Quartcrly Monitoring Repon12011 Q313rd Qlr201 ) GW.doc
2.4.2 Regulatory Framework and Groundwater Background
As a result of the issuance of the revised GWDP on January 20, 2010, which sets revised
GWCLs, all requirements to perform accelerated monitoring under Part I.G.1 of the
previous GWDP ceased effective on January 20, 2010, and the effect of the issuance of
the revised GWDP was to create a "clean slate" for all constituents in all wells going
forward.
This means that accelerated monitoring during the third quarter 2011 was required under
the revised GWDP for only those constituents that exceeded the GWCLs in 2010.
2.4.3 Compliance Status
Analytes which have exceeded the GWCLs set forth in the GWDP are summarized in
Table 2. The analytes which exceeded their respective GWCLs during the third quarter
2011 will be sampled on an accelerated schedule as noted in Table 2. Analytes which
exceeded their respective GWCLs during 2010 are currently sampled on an accelerated
schedule. A review of the accelerated data collected during third quarter 2011 indicate
that several analytes have exceeded their respective GWCLs for two consecutive
sampling periods as reported in DUSA's letter to DRC on November 3, 2011. Table 3
summarizes the results of the accelerated sampling program from first quarter 2010
through first quarter 2011.
Part I.G.1 c) of the GWDP states, with respect to exceedances of GWCLs, "that the
Permittee shall prepare and submit within 30 calendar days to the Executive Secretary a
plan and a time schedule for assessment of the sources, extent and potential dispersion of
the contamination, and an evaluation of potential remedial action to restore and maintain
groundwater quality to insure that Permit limits will not be exceeded at the compliance
monitoring point and that DMT or BAT will be reestablished." DUSA submitted an
exceedance notice on November 3,2011 for the third quarter 2011 results. The summary
in the Exceedance Notice includes, for each exceedance, a brief discussion of whether
such a plan and schedule is required at this time in light of other actions cUlTently being
undertaken by Denison, as determined by Utah Department of Environmental Quality
("UDEQ") Staff and stated in teleconferences with Denison on April 27 and May 2,
2011. The applicability of the plans and time schedules for assessment was submitted to
the Executive Secretary in the November 3,2011 Exceedance Notice.
2.5 Depth to Groundwater and Water Table Contour Map
As stated above, a listing of groundwater level readings for the quarter (shown as depth to
groundwater in feet) is included under Tab D. The data from Tab D has been interpreted
(kriged) and plotted in a water table contour map, provided under Tab H.
The water table contour map provides the location and identity of all of the wells and
piezometers for which depth to groundwater is recorded. The groundwater elevation at
each well and piezometer, measured in feet above mean sea level, and isocontour lines to
5
N:IRequircd RepollslGruundwaler Quarterly Moniloring Repor[12011 Q313rd QIr 20 11 GW.doc
delineate groundwater flow directions observed during the quarter's sampling event, are
displayed on the map.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The Mill QA Manager performed a QNQC 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 quality control 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 laboratory data QNQC are discussed
in Sections 3.4.4 through 3.4.9 below.
The Analytical Laboratories have provided summary reports of the analytical QNQC
measurements necessary to maintain conformance 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 forms for each set of Analytical Results,
follow the analytical results under Tabs E and F. Results of review of the laboratory
QNQC information are provided under Tab G and discussed in Section 3.4, below.
3.1 Field QC Samples
The following field 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:
Two duplicate samples were collected during quarterly sampling as indicated in Table 1.
The QC samples were sent blind to the analytical laboratory and analyzed for the same
parameters as permit-required samples.
One duplicate sample was collected during each month of accelerated sampling as
indicated in Table 1. The QC samples were sent blind to the analytical laboratory and
analyzed for the same accelerated parameters as the parent sample.
Two trip blanks were provided by EL and returned and analyzed with the quarterly
monitoring samples.
One trip blank per month was provided by EL and returned and analyzed with the
accelerated monthly monitoring samples.
Two trip blanks were provided by AWAL and returned and analyzed with the quarterly
monitoring samples.
6
N:lRequired ReportslOroundwaler Quarterly Monitoring Reporl120 II Q313rd Qlr 20 II OW.doc
One trip blank per month was provided by A W AL and returned and analyzed with the
accelerated monitoring samples.
Rinsate samples were not collected during the third quarter 2011 because all equipment
used during sample collection was dedicated and did not require decontamination. All
wells except MW-37 have dedicated pumps for purging and sampling and as such no
rinsate blanks samples are required. MW-37 was sampled with a disposable bailer and
no rinsate blank was required. A deionized field blank (DIFB) was not required because
equipment decontamination was not required and deionized water was not used during
this sampling event.
Duplicate and trip blank sample results are shown in 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 SOP's were implemented, except as described below.
3.3 Analyte Completeness Review
All analyses required by the GWDP for the quarterly wells were performed. The
accelerated quarterly sampling (quarterly to monthly and semi-annual to quarterly)
required for this quarter, as shown in Tables 2 and 3, was performed.
3.4 Data Validation
The QAP and GWDP identify the data validation steps and data quality control checks
required for the groundwater monitoring program. Consistent with these requirements,
the QA Manager performed the following evaluations: a field data QAlQC evaluation, a
receipt temperature check, a holding time check, an analytical method check, a reporting
limit check, a trip blank check, a QAlQC evaluation of routine sample duplicates, a
QAlQC evaluation of accelerated sample duplicates, a gross alpha counting error
evaluation and a review of each laboratory's reported QAlQC information. Each
evaluation is discussed in the following sections. Data check tables indicating the results
of each test are provided under Tab G.
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
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 were conducted within a five-
day period. The results of this quarter's review are provided in Tab G.
7
N:IR<quired ReportslGroundwater Quarterly Monitoring Reporl120 II Q313rd Qlr 20J I GW.doc
Based upon this review, all quarterly sampled locations conformed to the QAP
requirement to evacuate two well casing volumes before sampling except for MW-3A,
MW-12, MW-23 , MW-24 , and MW-37. In all cases these wells were evacuated to
dryness before two casing volumes could be purged.
All accelerated sampled locations conformed to the QAP requirement to evacuate two
well casing volumes before sampling.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water for the quarterly and accelerated sampling programs
to the nearest 0.01 foot.
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 have to be stabilized to within 10% over at least 2 consecutive
measurements. The QAP states that turbidity should be less than 5 Nephlometric
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 greater than 5 NTU below are included for information purposes only.
• Turbidity measurements were less than 5 NTU for all of the quarterly wells
except MW-5, MW-ll, MW-23 , MW-27, MW-29, MW-32, MW-32 res ample
and MW-37. The QAP does not require that turbidity measurements be less than 5
NTU prior to sampling. Per the QAP Section 6.2.7 d) (v) Turbidity measurements
prior to sampling were within a 10% Relative Percent Difference ("RPD") for all
quarterly sampling wells.
• Turbidity measurements were less than 5 NTU for all of the accelerated sampling
wells except MW -11. Turbidity measurements prior to sampling were within a
10% RPD for all accelerated sampling wells
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 groundwater
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 under Tab G. All samples were received and analyzed
within the required holding time.
8
N:lRcquiretl ReportslGroundwater Quarterly Moniloring Reportl2011 Q313rtl Qtr 2011 GW.doc
3.4.3 Receipt Temperature Evaluation
Chain of Custody sheets (for A W AL) and temperature blank data sheets (for EL) were
reviewed to confirm compliance with the QAP requirement in QAP Table 1 that samples
be received at 6°C or lower. Sample receipt temperature checks are provided under Tab
G. All quarterly and accelerated samples were received within the required temperature
limit.
3.4.4 Analytical Method Checklist
All analytical methods reported by both laboratories were checked against the required
methods specified in Table 1 of the QAP. Analytical method check results are provided
in Tab G. The review indicated that all quarterly and accelerated samples were analyzed
in accordance with Table 1 of the QAP.
It is recommended that the QAP be improved and updated to include additional
methodologies currently in use by other laboratories certified under the Environmental
Lab Certification Program administered by the Utah Department of Environmental
Quality ("UDEQ") Bureau of Lab Improvement. Potentially, to accommodate ongoing
improvement in technology and methodology, the entire Table 1 and the Chloroform
Investigation Appendix table should be revised to include other currently approved
analytical methods in use by other Utah certified laboratories.
3.4.5 Reporting Limit Evaluation
All analytical method reporting limits reported by both laboratories were checked against
the reporting limits specified in the QAP Table 1. Reporting limit evaluations are
provided in Tab G. All analytes were measured and reported to the required reporting
limits except several sets of routine and accelerated sample results had the reporting limit
raised for at least one anaiyte due to matrix interference and/or sample dilution as noted
in Section 3.4.9. In all cases the reported value for the analyte was higher than the
increased detection limit.
3.4.6 Trip Blank Evaluation
All trip blank results were reviewed to identify any blank contamination. Trip blank
evaluations are provided in Tab G. All trip blank results associated with both the
quarterly and accelerated samples were less than detection level for all VOCs.
3.4.7 QAlQC Evaluation for Routine 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
9
N:lRequired RcponslOroundwatcr Quanerly Monitoring Reponl20 II Q313rd Qtr 2011 GW.doc
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 with detections in both the
parent and duplicate sample 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 in the quarterly samples except for the
uranium result in the duplicate pair MW-26/MW-65. Duplicate results are provided
under Tab G.
All duplicate results were within a 20% RPD in the accelerated samples. Results of the
RPD test are provided under Tab G.
3.4.8 Radiologies Counting Error and Duplicate Evaluation
Section 9.14 of the QAP requires that all gross alpha analysis reported with an activity
equal to or greater than the GWCL, shall have a counting variance that is equal to or less
than 20% of the reported activity concentration. An error term may be greater than 20%
of the reported activity concentration when the sum of the activity concentration and
error term is less than or equal to the GWCL.
Section 9.4 of the QAP also requires a comparability check between the sample and field
duplicate sample results utilizing the formula provided in the text. The quarterly and
accelerated sample and duplicate results met the comparability check specified in the
QAP.
Results of quarterly and accelerated radiologic sample QC are provided under Tab G. All
quarterly and accelerated radiologic sample results met the counting error requirements
specified above.
3.4.9 Other Laboratory QAlQC
Section 9.2 of the QAP requires that the laboratory's QNQC 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
10
N:IRequircd RcportslGroundwater Quarterly Monitoring Reportl20 II Q313rd Q,r 2011 GW.doc
are provided under Tab G. All lab QNQC results from both EL and A W AL samples for
compounds regulated under the GWDP met these requirements. There were QC results
which did not meet laboratory established acceptance limits, as identified in Tab G and
described below.
There were no qualifiers attached to the A W AL tetrahydrofuran data.
Fourteen sets of quarterly sample results (twelve wells and two duplicates) and seven sets
of accelerated samples (six samples and one duplicate) had the reporting limit raised for
at least one analyte due to matrix interference and/or sample dilution. In all cases the
reported value for the analyte was higher than the increased detection limit. Data are
qualified by the laboratory with a "D" flag when the reporting limit is raised due to
dilution or matrix interferences.
The check samples included at least the following: a method blank, a laboratory control
spike ("LCS"), a matrix spike ("MS") and a matrix spike duplicate ("MSD"), or the
equivalent, where applicable. It should be noted that:
• Laboratory fortified blanks are equivalent to LCSs.
• Laboratory reagent blanks are equivalent to method blanks.
• Post digestion spikes are equivalent to MSs.
• Post digestion spike duplicates are equivalent to MSDs.
• For method E900.1, used to determine gross alpha, a sample duplicate was
used instead of a MSD.
All qualifiers, and the corresponding explanations reported in the QNQC Summary
Reports for any of the check samples for any of the analytical methods were reviewed by
the QA Manager.
The QAP Section 8.1.2 requires that a 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 a 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 QNQC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all quarterly samples were within
acceptable laboratory limits for all regulated compounds except as indicated in Tab G.
The recoveries and RPDs which are outside of the laboratory established acceptance
limits do not affect the quality or usability of the data because the recoveries and RPDs
outside of the acceptance limits are indicative of matrix interference. Furthermore, the
11
N:lRequired ReportslGroundwater Quarterly Monitoring ReporLI2011 Q313rd Qlr 20 II GW.doc
quarterly VOC sample (C11080529) and two of the metals samples (CI1090045) that
were spiked for the MS/MSD analyses were not collected at the Mill, and as such the
matrix interference is not applicable to the Mill samples reported herein. 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 QAlQC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all accelerated samples were within
acceptable laboratory limits for all regulated compounds except as indicated in Tab G.
The percent recovery for the July monthly manganese sample in (Cl1070824) spiked for
the MS/MSD analyses was not collected at the Mill, and as such the matrix interference is
not applicable to the Mill samples reported herein. 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 QAP specifies that surrogate compounds shall be employed for all organic analyses
but the QAP does not specify acceptance limits for surrogate recoveries. The analytical
data associated with the quarterly and accelerated sampling met the requirement specified
in the QAP. The information from the Laboratory QAlQC Summary Reports indicates
that the surrogate recoveries for all quarterly samples were within acceptable laboratory
limits for all surrogate compounds except as indicated in Tab G. In all instances the
surrogate recoveries outside of acceptance limits were above the upper limit or had a high
recovery, indicating a high bias to the individual sample results. A high bias means that
reported results for this analyte will tend to be higher than the actual concentration.
There is no effect on the quality or usability of the data because there are multiple
surrogates added to each sample and all other surrogates were within limits. Furthermore,
there are no QAP requirements for surrogate recoveries. Since surrogate compounds
were added to all of the organic analyses as required by the QAP, the data are compliant
with the QAP requirements.
The information from the Laboratory QAlQC Summary Reports indicates that the LCS
recoveries for both the quarterly and accelerated samples were within acceptable
laboratory limits for all LCS compounds.
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. For the Mill samples, a method blank is
prepared for all analytical methods. Per the approved QAP, contamination detected in
analysis of method blanks will be used to evaluate any analytical laboratory
contamination of environmental samples. The QAP does not specify the process for
evaluation of method blanks. For consistency, the QAP required evaluation criteria for
rinsate blanks will be used. The QAP criteria for rinsate blanks states that
nonconformance will exist when blanks are within an order of magnitude of the sample
results. Two analytes (selenium in the July accelerated samples and bicarbonate in the
third quarter samples) were reported in the method blanks from EL. Method blank results
are included in Tab E. In all cases where the associated sample reported a positive
12
N:IRequired Rep0rlslGmundwater Quarterly MonitOring Reportl2011 Q313rd Qtr 2011 GW.doc
detection, the method blank results were less than an order of magnitude relative to the
positive sample results reported, that is the detections meet the QAP criteria. The method
blank detections reported by EL do not affect the quality or usability of the data due to
the high level of the constituents in the samples relative to the associated method blank
concentrations. Additionally, blank detections are indicative of a false positive or high
bias to the sample results as the laboratory contribution to the results would likely cause
higher sample results. The QAP requirement to analyze a method blank with each batch
and evaluate the results has been completed as required.
It is important to note that the selenium detection in the method blank for the July
accelerated samples is the result of the low reporting limit (RL) used by EL for selenium,
which is lower than the RL for selenium used for the samples. The corrective action for
method blank detections in the Second Quarter 2011 Groundwater Report, submitted
August 31, 2011, specified that the RLs for method blanks would be changed to be the
same as the sample RLs. This corrective action was implemented as described in the
Second Quarter 2011 Groundwater Report beginning with the samples collected in
August 2011. The July data were received prior to completion of the corrective action
report submitted with the Second Quarter 2011 Groundwater Report on August 31, 2011.
4.0 CORRECTIVE ACTION REPORT
There are no corrective actions resulting from third quarter 2011 groundwater sampling
event.
4.1 Assessment of Previous Quarter's Corrective Actions
The second quarter 2011 report identified a corrective action for 29 low level detections
in the method blanks.
An investigation into the low level method blank detections in the second quarter of 2011
was completed by the QA Manager. The investigation indicated that the RLs used by the
laboratory for method blanks are below the QAP-required RLs used for groundwater
samples which results in numerous false detections to be reported in the method blanks.
DUSA directed EL to use the same QAP-required RLs for the method blanks as are used
for the groundwater samples to eliminate false reports of analytes in the method blanks
below the levels that are reported in the groundwater samples. The corrective action was
successful as the number of method blank detections reported in the third quarter 2011
decreased significantly and the problem has been eliminated. No further corrective
action is necessary at this time.
5.0 TIME CONCENTRATION PLOTS
Time concentration plots for each monitoring well for the following constituents:
chloride, fluoride, sulfate, and uranium, are included under Tab 1. Time concentration
plots are completed consistent with the EPA Document Statistical Analysis of
13
N:lRequired Rep0rlslGroundwalcr Quarterly Monitoring Rcporll20 II Q3131 d Qlr 20 II GW.doc
Groundwater Monitoring Data at ReRA Facilities, Unified Guidance, March 2009

exceeds three hmes the mterquarttle range above the 75t percentile and below the 25 th
percentile) are removed. For the purpose of compliance, extreme outliers are not
removed.
6.0 ELECTRONIC DATA FILES AND FORMAT
DUSA has provided to the Executive Secretary electronic copies of all laboratory results
from groundwater quality monitoring conducted during the quarter in Comma Separated
Values ("CSV"), from the EL data; and in Electronic Data Deliverable C'EOD") format
from the A W AL data. A copy of the transmittal e-mail is included under Tab J.

RE: 3rd Quarter Ground Water 2011
Dear Jo Ann Tischler: Lab Set ID: 1108108
American West Analytical Laboratories received 9 sample(s) on 8/5/2011 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado, Idaho, and Missouri.
Certification document is available upon request. If you have any questions or concerns
regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, andlor
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be reported
by the method referenced and the sample matrix. The reporting limit must not be confused
with any regulatory limit. Analytical results are reported to three significant figures for
quality control and calculation purposes.
Thank You,
Approved by:

RE: 3rd Quarter Ground Water 2011
Dear JoAnn Tischler: Lab Set ID: 1108246
American West Analytical Laboratories received 3 sample(s) on 8/12/2011 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado, Idaho, and Missouri.
Certification document is available upon request. If you have any questions or concerns
regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be reported
by the method referenced and the sample matrix. The reporting limit must not be confused
with any regulatory limit. Analytical results are reported to three significant figures for
quality control and calculation purposes.

CLIENT: Denison Mines USA Corp Revised Date: 10/07/11
Project: 3rd Quarter Groundwater Resample 2011 Report Date: 10/04/11
Sample Delivery Group: Cl1090045 CASE NARRATIVE
REVISED/SUPPLEMENTAL REPORT
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
October 6, 2011 for the addition of cations on samples -001 through -006. The data presented here is from that additional
analysis.
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.
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.

Sample Delivery Group: C11090914 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 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.

Sample Delivery Group: C11080529 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.

RE: July Monthly Ground Water 2011
Dear Jo Ann Tischler: Lab Set ID: 1107136
American West Analytical Laboratories received 2 sample(s) on 7/8/2011 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado and Idaho. Certification
document is available upon request. If you have any questions or concerns regarding this
report please feel free to call.
The abbreviation "SUff" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitaion limit (PQL). This is the minimum concentration that can be reported
by the method referenced and the sample matrix. The reporting limit must not be confused
with any regulatory limit. Analytical results are reported to three significant figures for
quality control and calculation purposes.

CLIENT: Denison Mines USA Corp
Project: July Monthly Groundwater 2011 Report Date: 08/01/11
Sample Delivery Group: C11070274 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 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.

Sample Delivery Group: C11070824 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 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.

RE: September Monthly Ground Water 2011
Dear Jo Ann Tischler: Lab Set ill: 1109163
American West Analytical Laboratories received 2 sample(s) on 9/9/2011 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado, Idaho, and Missouri.
Certification document is available upon request. If you have any questions or concerns
regarding this report please feel free to call.
The abbreviation "SUIT" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, andlor
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be reported
by the method referenced and the sample matrix. The reporting limit must not be confused
with any regulatory limit. Analytical results are reported to three significant figures for
quality control and calculation purposes.
Thank You, Digitally signed by Jose G.

Tetrahydrofuran
General Set Comments: Tetrahydrofuran was observed in the Trip Blank above reporting
limits. To confirm the result of the first vial, a second sample vial was analyzed with a
similar result. The result in sample MW-11 was < 1.00 /lg/L and therefore demonstrates
that the contamination in the Trip Blank did not occur during the analysis. It is important to
note that the vials used for the Trip Blanks were not provided by American West Analytical
Laboratories.
Holding Time and Preservation Requirements: All samples were received in appropriate
containers and properly preserved. The analysis and preparation of all samples were
performed within the method holding times following the methods stated on the analytical
reports.
Analytical QC Requirements: All instrument calibration and calibration check
requirements were met. All internal standard recoveries met method criterion.
Batch QC Requirements: MB, LCS, MS, MSD, RPD, and Surrogates:
Method Blanks (MBs): No target analytes were detected above reporting limits,
indicating that the procedure was free from contamination.
Laboratory Control Sample (LCSs): All LCS recoveries were within control
limits, indicating that the preparation and analysis were in control.
Matrix Spike 1 Matrix Spike Duplicate (MS/MSD): All percent recoveries and
RPDs (Relative Percent Differences) were inside established limits, indicating no
apparent matrix interferences.
Surrogates: All surrogate recoveries were within established limits.
Corrective Action: None required.

Sample Delivery Group: C 11090325 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.
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.

The QAP states that turbidity should be less than 5 Nephelometric Turbidity Units (HNTV") 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 are included for information purposes only.
MW -26 is a continuously pumped well. Per the QAP, only one set of parameters are required to be collected from continuously pumped wells.
Well was pumped dry
N/ A = The amount of water in the well was insufficient to pump. The pump was not able to operate due to the minimal amount of water. The well was sampled with a bailer.
