1.0 INTRODUCTION
This is the Routine Groundwater Monitoring Report, as required under Part I.F.1 of State
of Utah Groundwater Discharge Pennit No. UGW370004 (the "GWDP") for the first
quarter of 2012 (the "quarter") for Denison Mines (USA) Corp's. ("DUSA's") White
Mesa Uranium Mill (the "Mill"). As required under Parts I.E. 1 , I.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.
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, chlorofonn 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 first quarter included
both quarterly and accelerated monitoring. Accelerated monitoring is discussed below in
Section 2.1.2. In this first 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 I.E.1.c) 2)ii of the GWDP
dated 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 previous reports.
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
quarter, MW -26 and the duplicate MW -65 were resampled for metals and Gross Alpha
due to preservation (PH) outside of acceptance limits when the samples were received at
the laboratory. In addition MW -26 and the duplicate were unnecessarily resampled for
THF because of a communication error. The extra THF data for MW -26 and MW -65 are
included for infonnation purposes.

N:\Required Reports\Oroundwater Quarterly Monitoring Report\2012 QI\lst Qtr 2012 OW.doc
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, have been sampled quarterly since third quarter 2011.
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 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 July 14, 2011:
• The groundwater compliance monitoring wells including MW -20, MW -22, MW-
34, MW-35, 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-5.
• Nitrate monitoring wells.
• The DR piezometers which were installed during the Southwest Hydrogeologic
Investigation.
2
N :\Required Reports\Groundwater Quarterly Monitoring Report\20 12 Q 1\1 st Qtr 2012 GW.doc
• 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 5 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
January and March 2012 accelerated monitoring and sampling efforts.
2.3 Laboratory Results -Quarterly Sampling
2.3.1 Copy of Laboratory Results
All analytical results are provided by one of the Mill's two contract analytical
laboratories Energy Laboratories ("EL") or America West Analytical Laboratories

N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Ql\lst Qtr 2012 GW.doc
2.3.2 Regulatory Framework and Groundwater Background
Under the GWDP (July 14,2011), background groundwater quality has been detennined
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 detennined the
accelerated monthly monitoring program implemented during this quarter.
Exceedances of the GWCLs for the first quarter (January through March) of2012 are
listed in Table 2 for sampling required under the revised GWDP (July 14, 2011). 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 nonnally
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.
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 perfonn 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 first quarter 2012 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 first quarter
2012 will be sampled on an accelerated schedule as noted in Table 2. Analytes which
4
N :\Required Reports\Groundwater Quarterly Monitoring Report\20 12 Q 1 \ 1 st Qtr 2012 GW.doc
exceeded their respective GWCLs during 2010 are currently sampled on an accelerated
schedule. A review of the accelerated data collected during first quarter 2012 indicate
that one analyte has exceeded its respective GWCLs for two consecutive sampling
periods as reported in DUSA's letter to DRC on May 11, 2012. Table 3 summarizes the
results of the accelerated sampling pro gram from first quarter 2010 through first quarter
2012.
Part LG.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 May 11, 2012 for the first quarter 2012 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 currently 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 May 11, 2012 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
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 QAlQC 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 QAlQC are discussed
in Sections 3.4.4 through 3.4.9 below.
5
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 QI \Ist Qtr 2012 GW.doc
The Analytical Laboratories have provided summary reports of the analytical QAlQC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The analytical laboratory QAlQC 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
QAlQC 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.
Three 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.
Four trip blanks were provided by A W AL and returned and analyzed with the quarterly
monitoring samples.
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 this quarter 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.

N :\Required Reports\Oroundwater Quarterly Monitoring Report\20 12 Q 1 \ 1 st Qtr 2012 OW.doc
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 perfonned. The
accelerated quarterly sampling (quarterly to monthly and semi-annual to quarterly)
required for this quarter, as shown in Tables 2 and 3, was perfonned.
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 perfonned 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, aQAlQC 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 infonnation. 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 perfonns a review of all field recorded parameters to assess their
adherence with QAP requirements. The assessment involved review of two sources of
infonnation: the Field Data Sheets and the Quarterly Depth to Water summary sheet.
Review of the Field Data Sheets addresses well purging volumes and stability of five
parameters: conductance, pH, temperature, redox potential, and turbidity. Review of the
Depth to Water data confinns that all depth measurements were conducted within a five-
day period. The results of this quarter's review are provided in Tab G.
Based upon this review, all quarterly sampled locations confonned 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 confonned 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.
7
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 QI\lst Qtr 2012 OW.doc
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 N ephlometric
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-19, MW-29, MW-32, 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.
The EL laboratory pH data are qualified with an "H" flag noting that the analyses were
performed beyond the recommended holding time. EL noted that per their last NELAC
audit, to maintain certification, all pH analyses that are not completed within 15 minutes
of sample collection are required to be qualified as completed beyond the recommended
holding time. It is important to note that those laboratory pH data are not used for
compliance or reporting purposes. Compliance with the pH GWCLs for all groundwater
samples is determined using the field pH collected immediately prior to sample
collection.
3.4.3 Receipt Temperature Evaluation
Chain of Custody sheets (for AWAL) and temperature blank data sheets (for EL) were
reviewed to confirm compliance with the QAP requirement in QAP Table 1 that samples
8
N:\Required Reports\Groundwater Quarterly Monitoring Report\20l2 Ql\lst Qtr 2012 GW.doc
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. A revised QAP is
currently in process which incorporates multiple methods for all analytes to allow
flexibility and to address improvements in technology. The Revised QAP will be
implemented upon receipt of approval byUDEQ.
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 analyte 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
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
9
N:\Required Reports\Groundwater Quarterly Monitoring Report\20l2 Ql\lst Qtr 2012 GW.doc
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
chloride result in the duplicate pair MW -26/MW -65. Duplicate results are provided
under Tab G. A revised QAP is currently in progress (Revision 7.1). In response to
requests from UDEQ, a separate corrective action for duplicate RPDs outside of
acceptance limits has been developed and was documented in the revised QAP. The
revised procedure for duplicate results outside of acceptance limits was implemented
during the first quarter 2012 for the chloride results in duplicate pair MW-26/MW-65.
The corrective actions that were taken in accordance with the revised procedure are as
follows: the QA Manager contacted the Analytical Laboratory and requested a review of
the raw data to assure that there were no transcription errors and the data were accurately
reported. The laboratory noted that the data were accurate and reported correctly.
Reanalysis was not completed as the samples were beyond the holding time.
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 Radiologics 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 QAlQC Manager check the
following items in developing data reports: (l) sample preparation information is correct
and complete, (2) analysis information is correct and complete, (3) appropriate analytical
laboratory procedures are followed, (4) analytical results are correct and complete, (5)
10

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 under Tab G. All lab QAlQC 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.
Fifteen sets of quarterly sample results (thirteen 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 QAIQC 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.
11
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 QI\lst Qtr 2012 GW.doc
The information from the Laboratory QA/QC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all quarterly and monthly accelerated
samples were within acceptable laboratory limits for all regulated compounds except as
indicated in Tab G. The recoveries which are above the laboratory established acceptance
limits do not affect the quality or usability of the data because the recoveries outside of
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.
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 and monthly accelerated 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 the quarterly samples were within acceptable laboratory limits for all LCS
compounds.
The information from the Laboratory QAlQC Summary Reports indicates that the LCS
recoveries for the accelerated monthly samples were within acceptable laboratory limits
for all LCS compounds except as indicated in Tab G. In all instances the LCS compound
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 compounds in the
LCS and all other LCS compounds were within limits. Furthermore, there are no QAP
requirements for LCS recoveries. The QAP requirement to analyze an LCS with each
analytical batch was met and as such the data are compliant with the QAP.
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
12
N:\Required Reports\Groundwater Quarterly Monitoring Report\20 12 Q 1 \1 st Qtr 2012 GW.doc
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 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
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 detection reported by EL does 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.
4.0 CORRECTIVE ACTION REPORT
A revised QAP is currently in progress (Revision 7.1). In response to requests from
UDEQ, a separate corrective action for duplicate RPDs outside of acceptance limits has
been developed and was documented in the revised QAP. The revised procedure for
duplicate results outside of acceptance limits was implemented during the first quarter
2012 for the chloride results in duplicate pair MW-26/MW-65. The corrective actions
that were taken in accordance with the revised procedure are as follows: the QA Manager
contacted the Analytical Laboratory and requested a review of the raw data to assure that
there were no transcription errors and the data were accurately reported. The laboratory
noted that the data were accurate and reported correctly. Reanalysis was not completed
as the samples were beyond the holding time.
There are no other corrective actions resulting from first quarter 2012 groundwater
sampling event.
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 I.
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 ("EDD") format
from the AWAL data. A copy of the transmittal e-mail is included under Tab J.

RE: 1st Quarter GW 2012
Dear Garrin Palmer: Lab Set ill: 1202256
American West Analytical Laboratories received 8 sample(s) on 2/16/2012 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 accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are 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.
Thank You, , Digitally signed by Jose G.

RE: 1st Quarter GW 2012
Dear Garrin Palmer: Lab Set ill: 1202257
American West Analytical Laboratories received 7 sample(s) on 2/16/2012 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 accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are 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.
QA Officer This is a revision to a report originally issued 3/5/2012. Pages 1 and 4-10 have been revised.
Thank You,

RE: 1st Quarter Ground Water 2012
Dear Garrin Palmer: Lab Set ill: 1203040
American West Analytical Laboratories received 3 sample(s) on 3/5/2012 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 accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are 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.
QA Officer This is a revision to a report originally issued 3/14/2012. This report contains results for
Tetrahydrofuran and Tin. All pages have been revised and updated for pagination.
Thank You, Digitally signed by Jose G.

RE: 1st Quarter Ground Water 2012
Dear Garrin Palmer: Lab Set ill: 1203144
American West Analytical Laboratories received 3 sample(s) on 3/9/2012 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 accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are 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.
Thank You,
Approved by:

RE: 1st Quarter GW 2012
Dear Kathy Weinel: Lab Set ill: 1205180
American West Analytical Laboratories received 4 sample(s) on 5/10/2012 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 accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are 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.
Thank You,
Approved by:

CASE NARRATIVE
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: C12030065 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

CLIENT: Denison Mines USA Corp
Project: 1 st Quarter Groundwater 2012 Report Date: 03/20/12
Sample Delivery Group: C12020681 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: January Monthly Groundwater 2012
Dear JoAnn Tischler: Lab Set ID: 1201399
American West Analytical Laboratories received 2 sample(s) on 1/27/2012 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 accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are 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, 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.

Sample Delivery Group: C12010822 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: March Monthly Ground Water 2012
Dear JoAnn Tischler: Lab Set ill: 1203257
American West Analytical Laboratories received 2 sample(s) on 3/16/2012 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 accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are 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.
Thank You, Digitally signed by Jose G.

Denison Mines USA Corp
Project: March Monthly Groundwater 2012
Sample Delivery Group: C12030624
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Report Date: 04/12/12
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.
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.
