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 second
quarter of 2011 (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, chloroform contaminant investigation wells and nitrate contaminant investigation
wells is attached under Tab A. Groundwater samples and measurements were taken
during this reporting period (April through June), as discussed in the remainder of this
section.
2.1.1 Groundwater Compliance Monitoring
Groundwater samples and field measurements collected during the second quarter
included quarterly, semi-annual and accelerated monitoring. Accelerated monitoring is
discussed below in Section 2.1.2. In this second quarter report, samples classified as
being collected quarterly include those wells which are sampled every quarter and the
wells sampled semi-annually. Wells which are sampled routinely every quarter and
semi-annually were analyzed for the parameters listed in Table 2 and Part I.E.l.c) 2) ii of
the GWDP dated February 15,2010.
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 and the
rinsate blank sample. During this quarter, several wells were resampled for
Tetrahydrofuran ("THF") and/or Volatile Organic Compounds ("VOCs") due to the
receipt temperature being out of compliance. MW -17 and its duplicate, MW -70, were
resampled for chloride only due to the Relative Percent Difference ("RPD") of the
original and duplicate samples being outside of acceptance limits. MW-35 was sampled
in April 2011 and was resampled in June 2011. MW-35 was initially sampled in April
2011 by use of a low flow pump. However, Denison did not feel the data in April 2011
could be relied upon because the sample was collected by a method (the low-flow pump)
that had not been authorized by UDEQ for this well. MW-35 was re-sampled on June 7,
2011 by an authorized method, that is, use of a high-flow removable pump. Subsequent
to the re-sampling, Denison received approval from UDEQ, in an email on June 9, 2011,
l
N:IRequired Rcporl,IGroundwaler Quartcily Monitoring Reporll20 II Q2120 I CQ2_GW _Rerort lexl.doc
for use of either type of pump. The second date with the notation "res ample" for wells
MW-1, MW-17, MW-20, MW-28, MW-35 and MW-70 (duplicate of MW-17), reflect
the date of the resampling efforts.
2.1.2 Accelerated Groundwater Monitoring.
Accelerated monthly sampling was also performed (quruterly wells to monthly), and
results reported, for the wells indicated in Table 1. The accelerated sampling frequency,
analyte list and well list were determined based on the previous analytical results as
shown in Table 2.
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).
MW-35 was installed September 1 and 2, 2010 as required by the GWDP. MW-35 was
developed and quarterly sampling was initiated beginning in fourth quarter 2010.
GWCLs were set in the February 15, 2011 revision to the GWDP. The GWCL
exceedances noted for the fourth quarter 2010 in Table 3 were not noted in the Q4 2010
Exceedance Notice because the Exceedance Notice for fourth quarter 2011 was submitted
to UDEQ on February 14, 2011, prior to the GWDP revision date of February 15, 2011
and the GWDP receipt date of February 18, 2011. It should be noted that during Q1,
MW-35 was sampled on February 14, 2011, prior to Denison's receipt on February 18,
2011 of the revised GWDP containing GWCLs dated February 15, 2011. At the time of
the Q1 sampling, the current GWCLs were not applicable to MW-35. Therefore
sampling results from MW-35 were not addressed in the Q1 Exceedance Notice dated
May 13, 2011, because the GWCLs for this well were not in effect at the time of
sampling. Nonetheless, MW-35 was sampled in June 2011, and has been sampled
monthly thereafter as would have been the case had any GWCLs been in effect.
2.1.3 Background Well Monitoring
A requirement was added to the GWDP on March 17, 2008, which required the Mill to
begin quarterly sampling of wells MW-20 and MW-22 to develop eight quarters of
background data. A background report for MW-20 and MW-22 was submitted on June 9,
2010. The Utah Division of Radiation Control ("DRC") has since determined that these
wells will not serve as point of compliance wells, but will continue to be sampled semi-
annually as "general monitoring wells." MW-20 and MW-22 were sampled during the
second quarter 2011 to keep them on the same schedule as the other semi-annual wells.
Additionally, per the revised GWDP dated February 15,2011, MW-35 will be monitored
for eight consecutive quarters to establish background data. MW-33 is consistently dry
and will not be monitored. Per the revised GWDP dated February 15,2011, MW-34 will
only be included in the quarterly depth to water measurements and will not be sampled
for any of the analytes listed in Table 2 of the revised GWDP dated February 15, 2011;
however, MW -34 was inadvertently sampled during the second quarter of 2011. The
2
N:IRequired RcporLslGroundwater QUalterly Monitoring Repunl20 II Q2120J I_Q2_GW_RcporL texl.doc
data for MW-34 is included for information purposes only. Table 1 indicates the
sampling dates and the dates DUSA received laboratory data for these wells.
2.1.4 Parameters Analyzed
All routine quarterly and semi-annual groundwater monitoring samples were analyzed for
the parameters listed in Table 2 and Part I.E.I.c) 2) ii of the GWDP dated February 15,
2011. The accelerated monitoring samples were analyzed for a more limited and specific
parameter list as shown in Table 2.
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 15,2011:
• The quarterly groundwater compliance monitoring wells (including MW-33,
MW-34, and MW-35 if water was present).
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-l, P-2, P-3, P-4 and P-5.
• Nitrate monitoring wells.
• In addition to the above, depth to water measurements are routinely observed III
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 (sampled in April) for the groundwater compliance monitoring wells
referred to in paragraph 2.1.1, above. Sampling dates are listed in Table 1. Tab B also
includes field data sheets for general monitoring wells MW-20 and MW-22, which were
monitored during second quarter 2011 as the first semi-annual event.
Attached under Tab C are copies of all field data sheets recorded in association with the
May and June 2011 accelerated monitoring and sampling efforts.
It is important to note that the field data sheet appearance has changed as a result of the
implementation of an electronic data capture system. The field data sheets contain the
3
N:IRcquired RcporlslGroundwalcr Quallefly Monitoring RepOlll20 II Q2120 II_Q2_GW _Rep0rllexl.doc
same information as the field data sheet attached to the approved QAP in approximately
the same location. There are absolutely no changes in the information collected on the
electronic capture field form. All data are still collected using a pen and the hard copy
form. The difference in the field form is the formatting of the cells which now have
boxes around the input areas rather than plain lines. The new data sheets allow the
electronic capture of data while still maintaining the real-time recording of information
manually in ink as required by UDEQ. The changes were made to accommodate the data
recording and validation system. It is also important to note that the approved QAP,
Section 7.1 requires the use of a field data sheet, and notes that "An example of a Field
Data Worksheet that incorporates ... .is included as Attachment I." The QAP does not
state that the form included in Attachment 1 will be used, but is an example of a form that
incorporates the required information. Based on the wording of the currently approved
QAP, any form that incorporates the required information is allowable. The wording in
the approved QAP does not preclude the use of a re-formatted Field Data Worksheet
provided the required information is collected.
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
("AWAL").
Table 1 lists the dates when analytical results were reported to the Quality Assurance
("QA") Manager for each well.
Results from analysis of samples collected for the second under the GWDP (i.e., all
regular quarterly and semi-annual samples), as well as results from general monitoring
wells MW-20 and MW-22, which will be sampled semi-annually, are provided in Tab E.
Also included under Tab E are the results of analyses for duplicate samples and the
rinsate blank sample for this sampling effort, as identified in Table 1.
The laboratory report dates for samples collected for the May and June accelerated
sampling (i.e. quarterly accelerated to monthly) are provided in Table 1. Results from
analysis of samples collected for the May and June accelerated sampling (i.e. quarterly
accelerated to monthly) are provided in Tab F. Also included under Tab F are the results
of analyses for duplicate samples for this sampling effort, as identified in Table 1.
Copies of laboratory QAlQuality Control ("QC") Summaries are included with the
reported data under their corresponding Tabs.
2.3.2 Regulatory Framework and Groundwater Background
Under the GWDP dated February 15, 2011, background groundwater quality has been
determined on a well-by-well basis, as defined by the mean plus second standard
4
N:IRequired ReportslGroundwaLcr Quarterly MoniLoring RcporLI20 II Q2121J II_Q2_GW _Report Lext.doc
deviation concentration or the equivalent. New GWCLs that reflect this background
groundwater quality have been set for all monitoring wells. It is important to note that
the GWDP dated February 15,2011 also set GWCLs for MW-35. The GWCLs for MW-
35 have been set at one-quarter of the Utah Groundwater Quality Standard ("GWQS"),
pending determination of background for the well, and are not based on eight quarters of
data from that well. A background report for MW -35 will be completed after the
collection of eight quarters of data.
Exceedances of the GWCLs determined the accelerated monthly monitoring program
implemented during this quarter as noted in Tables 1 and 2.
Exceedances of the GWCLs for the second quarter (April through June) of 2011 are listed
in Table 2 for sampling required under the revised GWDP February 15, 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 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.
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 J.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 second quarter was required under the
revised GWDP for only those constituents that exceeded the GWCLs since January 20,
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 second quarter
2011 will be sampled on an accelerated schedule as noted in Table 2. Analytes which
5
N:IRequjred Rep0rlslGroundwaler Quarterly Monitoring Reportl2011 Q2120 I 1_Q2_GW_Report text.doc
exceeded their respective GWCLs during 2010 are currently sampled on an accelerated
schedule. A review of the accelerated data collected during second 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 August 8, 2011. Table 3
summarizes the results of the accelerated sampling program from first quarter 2010
through second quarter 2011.
Part I.G.l 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 August 8, 2011 for the second 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 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. Where applicable, the plans and time schedules for assessment will be submitted
to the Executive Secretary within 30 days of the August 8,2011 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
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 3.4.10 below.
6
N:\Required ReporL,IGroundwater Quanerly MonitoliIlg Reportl2011 Q212011_Q2_GW_Rcporllcxt.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.
Five 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.
Five 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 also collected prior to well samples where nondedicated purging
equipment was used. Rinsate samples were labeled with the name of the subsequently
purged well with a terminal letter "R" added (e.g. TW4-7R). The results of these
analyses are included with the routine analyses under Tab E. One rinsate blank sample
was collected during this quarterly sampling event as indicated in Table 1. All of the
groundwater wells have dedicated sampling equipment except MW-34 and MW-35.
MW-34 was sampled with a disposable bailer and as such no rinsate blank sample was
required. A rinsate blank sample was collected from the pump prior to the collection of
MW-35.

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 and semi-annual wells were
performed. The accelerated sampling for the semi-annual wells (semi-annual to
quarterly) was completed as required by the GWDP and as shown in Tables 2 and 3. The
accelerated quarterly sampling (quarterly to monthly) required for this quarter, as shown
in Tables 2 and 3, was performed as required.
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.
Based upon this review, all quarterly and semi-annually sampled locations conformed to
the QAP requirement to evacuate two well casing volumes before sampling except for
MW-12, MW-20, MW-23 , and MW-24. MW-12, MW-20, MW-23, and MW-24 were
evacuated to dryness before two casing volumes could be pumped. MW-34 had
insufficient water to purge and the pump would not operate due to the insufficient amount
of water in the well. Due to the small volume of water present, a sample was collected
using a disposable bailer. It should be noted that MW-3A and MW-35 were pumped dry
after purging two casing volumes.
All accelerated sampled locations conformed to the QAP requirement to evacuate two
8
N:IReqll~ed ReportslGroundwalcr Qu.ltcrly Monitoring RepOltl20 II Q2120 II_Q2_GW _Report [eXl.doc
well casing volumes before sampling except MW -26 which is a continuously pumped
well. If a well is continuously pumped, it is pumped on a set schedule per the
remediation plan and is considered sufficiently evacuated to immediately collect a
sample; however, if a pumping well has been out of service for 48 hours or more, DUSA
will follow the purging requirements outlined in Section 6.2.7(d)(v) of the QAP.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water for the quarterly, semi-annual 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 and semi-
annual wells except MW-I resample, MW-5, MW-12, MW-20 resample, MW-22,
MW-29, MW-34 and MW-35. 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 and semi-annual wells except MW-20 resample and
MW-35. MW-20 resample was purged to dryness prior to achieving stabilization
and MW-35 was purged dry after 2 casing volumes were removed but prior to
stabilization within 10%. As such the requirement to achieve an RPD of 10% or
less is not applicable. 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 program reviewed the available turbidity data for
the nitrate wells and developed a list of wells that have undergone redevelopment
utilizing several strategies. The redevelopment strategies include additional
surging and bailing and overpumping as necessary. Surging and bailing and
overpumping for the nitrate, chloroform, and groundwater wells is complete. Data
from the redevelopment of the groundwater wells will be reviewed with the data
from the redevelopment of the nitrate and chloroform programs. A single report
will be prepared at the completion of the redevelopment program for the wells in
all three programs which is planned for submittal on or before the end of the third
quarter 2011. DUSA will review the redevelopment data and summarize the
status of the Mill wells. Redevelopment results will be discussed with DRC in an
effort to come to a consensus regarding turbidity considerations for all of the
wells at the Mill site.
• Turbidity measurements were less than 5 NTU for all of the accelerated sampling

wells except MW -25 in both the May and June monthly sampling events and
MW-ll in the June monthly sampling event. As previously stated, the QAP does
not require that turbidity be less than 5 NTU. Turbidity measurements prior to
sampling were within a 10% RPD for all accelerated sampling wells. As
previously stated, the redevelopment program is completed and DUSA will
review the redevelopment data and summarize the status of the Mill wells.
Redevelopment results will be discussed with DRC in an effort to come to a
consensus regarding turbidity considerations for all of the wells at the Mill site.
All other field parameters (conductance, pH, redox potential, and temperature) for all
wells were within the required RPD for the quarterly, semi-annual and accelerated
sampling except redox potential in MW -20 resample and specific conductivity, redox
potential, and temperature in MW-35. MW-20 and MW-35 were both purged to dryness
prior to achieving stabilization and as such this requirement is not applicable.
3.4.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample
holding time checks are provided under Tab G. All samples were received and analyzed
within the required holding time.
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
be received at 6°C or lower. Sample receipt temperature checks are provided under Tab
G. All quarterly, semi-annual 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, semi-annual 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 quarterly, semi-annual 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 VOC sample contamination which is
the result of sample handling and shipment. Trip blank evaluations are provided in Tab
G. All trip blank results associated with both the quarterly, semi-annual 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
in the QAP. The RPDs are calculated for all duplicate pairs for all analytes regardless of
whether or not the reported concentrations are greater than 5 times the required detection
limits; however, data will be considered noncompliant only when the results are greater
than 5 times the required detection limit and the RPD is greater than 20%. The additional
duplicate information is provided for information purposes.
All duplicate results were within a 20% RPD in the quarterly and semi-annual samples.
Results of the RPD test 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 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.
11
N:lRcquired ReportslGroundwaLer Quarterly MoniLoring RepOlLI20 II Q212011_Q2_GW _Report LexL doc
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.
Results of quarterly, semi-annual, and accelerated radiologic sample QC are provided
under Tab G. All quarterly, semi-annual, and accelerated radiologic sample results met
the counting error requirement specified in the QAP.
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: (1) sample preparation information is correct
and complete, (2) analysis information is correct and complete, (3) appropriate analytical
laboratory procedures are followed, (4) analytical results are correct and complete, (5)
QC samples are within established control limits, (6) blanks are within QC limits, (7)
special sample preparation and analytical requirements have been met, and (8)
documentation is complete. In addition to other laboratory checks described above,
DUSA's QA Manager rechecks QC samples and blanks (items (5) and (6» to confirm
that the percent recovery for spikes and the relative percent difference for spike
duplicates are within the method-specific required limits, or that the case narrative
sufficiently explains any deviation from these limits. Results of this quantitative check
are provided 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.
There were no qualifiers attached to the A W AL tetrahydrofuran data.
Multiple sets of quarterly, semi-annual and accelerated sample results 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.
12
N:IRcquircd RepUltslGroundwalcr Quarterly Monitoring Rcportl2011 Q21201l_Q2_GW_Report text.doc
All qualifiers, and the corresponding explanations reported in the QA/QC 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 QAlQC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all quarterly and semi-annual samples
were within acceptable laboratory limits for all regulated compounds except as indicated
in Tab G. The recoveries and RPDs which are outside the laboratory established
acceptance limits do not affect the quality or usability of the data because the recoveries
and RPDs above or below the acceptance limits are indicative of matrix interference.
Matrix interferences are applicable to the individual sample results only. Furthermore,
the MS/MSD samples in Work Order Numbers Cl1040106, Cl1040612, Cl1060429
which 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 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
above the acceptance limits are indicative of matrix interference. Furthermore, the
MS/MSD samples in Work Order Number Cl1060884 which was 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 QAP specifies that surrogate compounds shall be employed for all organic analyses
but the QAP does not specify acceptance limits for surrogate recoveries. The information
from the Laboratory QAlQC Summary Reports indicates that the surrogate recoveries for
all quarterly, semi-annual and 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
13
N:lRequired ReporlslGroundwaler Quarterly Moniloring Repor[12011 Q2120 I I_Q2_GW_ReporlleXl.doc
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 RepOlts indicates that the LCS
recoveries for both the quarterly, semi-annual and accelerated samples were within
acceptable laboratory limits for all LCS compounds. 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
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. Twenty-nine analytes were reported in the method blanks from EL. The method
blank detections are a result of the low reporting limits (RLs) used by EL, which are
lower than the RLs used for the samples. 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. In many other instances method
blanks with positive detections for certain analytes were associated with samples that
were reported as nondetect for the same analyte. The majority of the method blank
detections are caused by the laboratory reporting detections in the method blanks below
the QAP required RL. The method blank detections reported by EL do not affect the
quality or usability of the data due to either the low level of the constituent in the method
blank (below the QAP-required RL) or 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. Corrective actions for the method blank contamination are
discussed in Section 4 of this report.
3.4.10 Rinsate Blank Samples
Rinsate blank sample checks are provided in Tab G. Per an e-mail from Mr. Phil Goble,
dated October 4, 2010, rinsate blank samples are only required at the beginning of the
14
N:lRequired RcponsIGroundw,(er QU'rterly Monitoring Repor(12011 Q212011_Q2_GW_Repon (ex(.doe
sampling event and at the beginning of each day of sampling. The frequency of rinsate
blank collection was acceptable this quarter.
A comparison of the rinsate blank sample concentration levels to the QAP requirements
-that rinsate sample concentrations be one order of magnitude lower than that of the
actual well -indicated that all of the rinsate blank analytes met this criterion except
chloroform. Chloroform contamination in rinsate blanks has been problematic during the
chloroform sampling programs at the Mill. Corrective actions and investigations are on-
going under the chloroform program.
A deionized field blank ("DIFB") is not required by the approved QAP but is collected
when DI water is used to collect rinsate blank samples to verify that the DI water is not
the source of contamination during the rinsate blank sampling process. The DIFB was
nondetect for all analytes except bicarbonate. The level of bicarbonate in the DIFB was
at least 2 orders of magnitude less than the associated groundwater sample and as such
had no affect on the quality or usability of the data.
4.0 CORRECTIVE ACTION REPORT
Necessary corrective actions identified during the current monitoring period are described
below, in accordance with Part I.F.t.e of the GWDP.
One item of note was identified during this reporting period which was a deviation from
requirements but is not discussed in the corrective action section below. The item is the
chloroform in the rinsate blank. This issue is discussed in detail in the chloroform report
for third quarter 2010 as well as the second quarter 2011 chloroform report. Corrective
actions to address the chloroform issue include upgrading the DI system. Completion of
the upgrades and corrective actions will be discussed in the chloroform report. In
addition, dedicated pumps have been installed in all of the groundwater wells and rinsate
blanks will no longer be collected under this program. If future sampling with a portable
pump is necessary, rinsate blanks will be collected and assessed as necessary.
4.1 Identification and Definition of the Problem
The problems identified were:
False Method Blank Contamination
Numerous positive detections in method blanks were reported by EL.
4.2 Assignment of Responsibility for Investigating the Problem
The problems have been investigated by the QA Manager.
15
N:IRequired ReportslGroundwuLer Quarterly MoniLOI ing RepOlLI20 11 Q2120 II_Q2_GW _RepOi L LexL.doc
4.3 Investigation and Determination of Cause of the Problem
False Method Blank Contamination
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.
4.4 Determination of a Corrective Action to Eliminate the Problem
False Method Blank Contamination
DUSA will direct 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.
4.5 Assigning and Accepting Responsibility for Implementing the Corrective
Action
It will be the responsibility of the QA Manager to implement the corrective action.
4.6 Implementing the Corrective Action and Evaluating Effectiveness
False Method Blank Contamination
Implementation of the corrective action for method blank RL changes will follow
direction to the laboratory.
4.7 Verifying That the Corrective Action Has Eliminated the Problem
Verification of the corrective action for the method blank RL changes will be completed
after the verification of the analytical data reports by the QA Manager.
4.8 Assessment of Corrective Actions from Previous Period
Below is a discussion of the corrective actions specified in previous reports.
The previous Groundwater Monitoring Reports noted that during Denison's management
review of groundwater QAlQC, an error was identified in the checking spreadsheet for
field pH. Correction of the spreadsheet resulted in corrections to some field pH entries
reported in the Exceedance Notices for QI through Q4, 2010. No other analytes were
affected. The corrections to the field pH values were the result of a spreadsheet error
which caused the incorrect reporting of several field pH values in Ql through Q4 2010.
All spreadsheets used for data checking have been verified. Additional staff were trained
to review data management tools and verify entries. The corrective action described
16
N:IRequired ReportslGroundwatcr Quarterly Monitoring Rcportl20 L 1 Q2120 L I_Q2_GW _Report text.doe
above is complete. The data management spreadsheets have been verified and all field
pH data have been corrected. The corrected values are currently reflected in the data
management tools in use. Additional verification will be conducted quarterly to assure
that the spreadsheets accurately reflect the reported values.
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 A W AL data. A copy of the transmittal e-mail is included under Tab J.

Notes:
I GWCL Values are taken from February 15. 20 I I version of the GWDP.
* THF has not reported an exceedance since QI 2010 and has had 13 consecutive monitoring results below the GWCL. Although based on previous instances, UDEQ has dropped
accelerated monitoring after 8 periods of results below the GWCL. UDEQ requires continued monitoring of this constituent.
** Table 2 of the 2010 Q3 Groundwater .report listed the start of accel~rat'7.d. monitoring as Q4 20 I O. Accelerated monitoring began i~ Q I 20 II.
sample period.
Highlighted text shows accelerated requirements resulting from Q2 20 II sampliog event.
2 The Q 1 2011 exceedances noted here were not reported in the Q 1 Exceedance Notice submitted May 13, 20 II because the Q2 sample was collected prior to
the GWCLs being set.

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

RE: 2nd Quarter Ground Water ISemi Annual Ground Water
Dear Jo Ann Tischler: Lab Set ID: 1104045
American West Analytical Laboratories received 4 sample(s) on 4/5/2011 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 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 "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to detennine 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.
Jose Rocha Thank You,
QA Officer F . Digitally signed by K~e F. Gross

RE: 2nd Quarter Ground Water 1 Semi Annual
Dear 10 Ann Tischler: Lab Set ID: II 04133
American West Analytical Laboratories received 12 sample(s) on 4/8/2011 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 "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 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.

RE: 2nd Quarter Ground Water 1 Semi Annual
Dear Jo Ann Tischler: Lab Set ID: 1104255
American West Analytical Laboratories received 15 sample(s) on 4/15/2011 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 "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 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.

Tetrahydrofuran
General Set Comments: Tetrahydrofuran was observed above reporting limits on sample
MW 5 (1104255-005A). Results could not be reported out for samples for MW 1
(1104255-001A) and MW 20 (1104255-008A) due to all VOA vials being received frozen
and broken.
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 I Matrix Spike Duplicate (MSIMSD): 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.

RE: 2nd Quarter Ground Water 1 Semi-Annual
Dear Jo Ann Tischler: Lab Set ID: 1104383
American West Analytical Laboratories received 2 sample(s) on 4/22/2011 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 "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 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.

RE: Semi Annual Ground Water 2011
Dear Jo Ann Tischler: Lab Set ID: 1106181
American West Analytical Laboratories received 5 sample(s) on 6/9/2011 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 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 "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 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.

Sample Delivery Group: C11040106 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.

Sample Delivery Group: Cll040280 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.

CLIENT: Denison Mines USA Corp
Project: 2nd Quarter Groundwater 2011 Report Date: OS/23/11
Sample Delivery Group: C11040506 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: C11040733 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 4B 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: C11050977 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
beginn ing 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: C11060429 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: May Monthly
Dear Jo Ann Tischler: Lab Set ID: 1105245
American West Analytical Laboratories received 2 sample( s) on 5/13/2011 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 "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to detennine 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.

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: June Monthly Ground Water 2011
Dear Jo Ann Tischler: Lab Set ID: 1106348
American West Analytical Laboratories received 2 sample(s) on 6/17/2011 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 "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 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.

Sample Delivery Group: C 11060884 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 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.

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

Mr. Lundberg,
Revised Q2 2011 Groundwater CSV Data for all Analytes
C11040506.CSV; 11 04255-EDD CSV -R2.csv
Denison Mines (USA) Corp. (DUSA) transmitted electronic files of the 02 2011 laboratory results for groundwater
monitoring conducted under the Groundwater Discharge Permit for White Mesa Mill on August 23, 2011.The transmittal
included fifteen attached files.
This transmittal includes 2 attached files intended to replace files 11042SS-EDD-R.csv and Cll040S06-R.CSV transmitted
on August 23, 2011. Since that date DUSA has noted that the files are incomplete and are missing the April 2011 data
for MW-3S. The attached file contains the missing data as well as the data for all of the other wells and analytes
contained in the original submission. These files should be used in place of the files submitted on August 23, 2011.
Please contact me if you have any questions on this submission
Yours Truly
Kathy Weinel
