1.0 INTRODUCTION
This is the Routine Groundwater Monitoring Report, as required under Part LF.1 of State
of Utah Groundwater Discharge Permit No. UGW370004 (the "GWDP") for the third
quarter of 2010 (the "quarter") for Denison Mines (USA) Corp's. ("DUSA's") White
Mesa Uranium Mill (the "Mill"). As required under Parts LE.1, I.E.2 and LE.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 (July through September), as discussed in the remainder of
this section.
2.1.1 Groundwater Compliance Monitoring
Groundwater samples and field measurements collected during the third quarter included
both quarterly and accelerated monitoring. Accelerated monitoring is discussed below in
Section 2.1.2. In this third quarter report, samples classified as being collected quarterly
include those wells which are routinely sampled every quarter as well as semi-annual
wells which are sampled on an accelerated quarterly schedule due to exceedances
reported in the second quarter report. Wells which are sampled routinely every quarter
were analyzed for the parameters listed in Table 2 and Part LE.l.c) 2)ii of the GWDP
dated June 17,2010. The semi-annual wells which have been accelerated to quarterly are
analyzed only for those parameters which exceeded the Groundwater Compliance Limits
("GWCLs") in Table 2 and Part LE.l.c) 2)ii of the GWDP as described in the 2nd
Quarter Groundwater Monitoring Report (DUSA August 26, 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). Several wells were
resampled for Tetrahydrofuran ("THF") due to the receipt temperature being out of
compliance. In addition, MW-27 was resampled for TDS as the original sample was not
analyzed for TDS prior to the holding time expiration. The second date with the notation
"resample" for wells MW-20, MW-26, MW-27, MW-30, MW-31, and MW-65 (duplicate
of MW-31), reflect the date of the resampling efforts. Table 1 also indicates which
sample numbers are associated with the required duplicates.

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 first and
second quarter analytical results and are included in Table 2. MW-30 was resampled for
selenium as it was inadvertently omitted from the original sample suite. The second date
with the notation "resample" for well MW-30 reflects the date of the resampling effort.
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 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. These two wells will continue to be monitored on a quarterly basis until such time
as the State of Utah Division of Radiation Control ("DRC") determines otherwise. Table
1 indicates the sampling dates and the dates DUSA received laboratory data for these
wells.
2.1.4 Parameters Analyzed
All routine quarterly groundwater monitoring samples were analyzed for the parameters
listed in Table 2 and Part I.E. I. c) 2)ii of the GWDP dated June 17,2010. 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 andlor piezometers, pursuant
to Part 1.E.2 of the GWDP dated June 17,2010:
• The quarterly groundwater compliance monitoring wells.
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-1, P-2, P-3, P-4 and P-S.
• Nitrate monitoring wells.
2
N:\Required ReportslGroundwater Quarterly Monitoring Report12010 Q312010 _ Q3 _ GW _Report text 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. Tab B also includes field data sheets
for background wells MW-20 and MW-22, which continue to be monitored quarterly.
Attached under Tab C are copies of all field data sheets recorded in association with the
July and August 2010 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
("A W AL").
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 quarter under the GWDP (i.e.,
all regular quarterly and semiannual samples), as well as results from background wells
MW-20 and MW-22, which continue to be sampled quarterly, are provided in Tab E.
Also included under Tab E are the results of analyses for duplicate samples for this
sampling effort, as identified in Table 1.
The laboratory report dates for samples collected for the July and August accelerated
sampling (i.e. quarterly accelerated to monthly) are provided in Table 1. Results from
analysis of samples collected for the July and August 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.

2.3.2 Regulatory Framework and Groundwater Background
Under the GWDP (June 17,2010), background groundwater quality has been determined
on a well-by-well basis, as defined by the mean plus second standard deviation
concentration or the equivalent. New GWCLs that reflect this background groundwater
quality have been set for all monitoring wells in the January 20, 2010 GWDP. These new
GWCLs were in effect for sampling required during the current third quarter monitoring
period.
Exceedances of the January 21, 2010 GWCLs as reported in the 1st quarter (January
through March) and second quarter (April through June) reports determined the
accelerated monthly monitoring program implemented during this quarter.
Exceedances of the GWCLs for the third quarter (July through September) of 2010 are
listed in Table 2 for sampling required under the revised GWDP (June 17,2010). 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 I.G.l of the
previous GWDP ceased effective on January 20,2010, and the effect of the issuance of
the revised GWDP was to create a "clean slate" for all constituents in all wells going
forward.
This means that accelerated monitoring during the third quarter was required under the
revised GWDP for only those constituents that exceeded the GWCLs in first and second
quarters of2010.

N:IRequired ReportslGroundwater Quarterly Monitoring Report120J 0 Q3120J 0_ Q3 _ GW _Report text doc
2.4.3 Compliance Status
Analytes which have exceeded the GWCLs set forth in the GWDP for the first, second,
and third quarters are summarized in Table 2. The analytes which exceeded their
respective GWCLs during the third quarter 2010 will be sampled on an accelerated
schedule as noted in Table 2. Analytes which exceeded their respective GWCLs during
the first and second quarters 2010 are currently sampled on an accelerated schedule. A
review of the accelerated data collected during third quarter 2010 indicate that several
analytes have exceeded their respective GWCLs for two consecutive sampling periods as
reported in DUSA's letter to DRC on November 12, 2010. Table 3 summarizes the
results of accelerated sampling program from first quarter 2010 through third quarter
2010.
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. In review of this form (which is not the
field data form contemplated by the White Mesa Uranium Mill Groundwater Monitoring
Quality Assurance Plan ["QAP"D it was noted that the millimeters of mercury (MMHG)
that is, the barometric pressure, was not recorded for the quarter. This measurement is
not required by either the Permit or the QAP and as such there is no effect on the data
collected and no corrective action is required. 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.
The Analytical Laboratories have provided summary reports of the analytical QAIQC
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
5
N:lRequired Repo"slGroundwater Qu."erly Monitoring Repo,,1201 0 Q312010 _ Q3 _ GW _Repo" text doc
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.
As previously stated, some locations were resampled due to the loss of the trip blank.
MW -65 (duplicate of MW -31) was resampled as part of this effort and as such appears
twice on Table 1. The QC samples were sent blind to the analytical laboratory and
analyzed for the same parameters as permit-required samples.
One duplicate sample was collected during each month of accelerated sampling as
indicated in Table 1. The QC samples were sent blind to the analytical laboratory and
analyzed for the same accelerated parameters as the parent sample.
Two trip blanks were provided by EL and returned and analyzed with the quarterly
monitoring samples.
One trip blank per month was provided by EL and returned and analyzed with the
accelerated monthly monitoring samples.
Two trip blanks were provided by A W AL and returned and analyzed with the quarterly
monitoring samples. As noted in Section 2.1.1, several wells were resampled for THF
due to the receipt temperature being out of compliance. To assure that all QAP required
QC samples were collected, the wells were resampled and submitted with the appropriate
QC samples (trip blank).
One trip blank per month was provided by A W AL and returned and analyzed with the
accelerated monitoring samples.
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 period were performed. In addition, all
accelerated sampling required for this quarter, as identified in Table 2, was performed.

3.4 Data Validation
The QAP and GWDP identify the data validation steps and data quality control checks
required for the groundwater monitoring program. Consistent with these requirements,
the QA Manager performed the following evaluations: a field data QAlQC evaluation, a
receipt temperature check, a holding time check, an analytical method check, a reporting
limit check, a trip blank check, a QAlQC evaluation of routine sample duplicates, a
QAlQC evaluation of accelerated sample duplicates, a gross alpha counting error
evaluation and a review of each laboratory's reported QAlQC information. Each
evaluation is discussed in the following sections. Data check tables indicating the results
of each test are provided under Tab G.
3.4.1 Field Data QAlQC Evaluation
The QA Manager performs a review of all field recorded parameters to assess their
adherence with QAP requirements. The assessment involved review of two sources of
information: the Field Data Sheets and the Quarterly Depth to Water summary sheet.
Review of the Field Data Sheets addresses well purging volumes and stability of five
parameters: conductance, pH, temperature, redox potential, and turbidity. Review of the
Depth to Water data confirms that all depth measurements were conducted within a five-
day period. The results of this quarter's review are provided in Tab G.
Based upon this review, all quarterly sampled locations conformed to the QAP
requirement to evacuate two well casing volumes before sampling except for MW-3A,
MW-20, and MW-23. In all cases these wells were evacuated to dryness before two
casing volumes could be pumped. Purge issues were noted for wells MW-12 and MW-
23. The Mill Staff noted that the flow rates decreased during purging, and it is unclear if
2 full casing volumes were purged prior to sample collection. The decreased flow rates
are indicative of the wells approaching dryness. Samples were collected at the
completion of the calculated purge times. Based on the decreased flow rate it appears
that the wells were recovering slower than the pump rate and formation water was being
drawn into the wells. Because the samples were formation water, these samples are
acceptable.
All accelerated sampled locations conformed to the QAP requirement to evacuate two
well casing volumes before sampling.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water for the quarterly sampling programs to the nearest
0.01 foot.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water for both the accelerated sampling programs to the
nearest 0.01 foot except MW-26 during the July sampling event. The Mill Staff noted
that the depth to water tape snagged at 83 feet 6 inches and it was not possible to collect a
7
N:lRequired ReponslGroundwater Quanerly Monitoring Repon1201 0 Q3120 10_ Q3 _ GW _Repon teKl-doc
depth to water measurement prior to sampling. MW -26 is a continuously pumped well
and the depth to water measurement is for information purposes only and does not affect
the usability of the data. There is no loss of data as a result of this measurement not
being collected.
The review of the field sheets for compliance with QAP requirements resulted in the
observations noted below. The QAP requirements in Section 6.2.7 specifically state that
field parameters have to be stabilized to within 10% over at least 2 consecutive
measurements. The QAP states that turbidity should be less than 5 Nephlometric
Turbidity Units ("NTU") prior to sampling unless the well is characterized by water that
has a higher turbidity. The QAP does not require that turbidity measurements be less
than 5 NTU prior to sampling. As such the noted observations regarding turbidity
measurements greater than 5 NTU below are included for information purposes only.
• Turbidity measurements were less than 5 NTU for all of the quarterly wells
except MW -22 and MW -32. 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 except MW -24. It is important to note
that the turbidity measurements for MW-24 were 0.7 NTU and 0.8 NTU which is
an RPD of 13.33%. Due to the numbers being less than 1, any difference would
produce a noncompliant RPD. The accuracy of the instrument is greater than the
difference between these two measurements. As such the data are usable and the
RPD is considered acceptable. 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 addition, DUSA is currently employing additional
well development strategies as required by DRC prior to DRC's consideration of
turbidity variances.
• Turbidity measurements were less than 5 NTU for all of the accelerated sampling
except MW-14, MW-26, and MW-31 in the July sampling event. MW-26 is a
continuously pumped well and the field parameters are used for informational
purposes only and not as an indication of stabilization. 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
except MW-14, MW-26, and MW-31. MW-14 and MW-31 were purged longer
than was required to purge 2 casing volumes in an attempt to achieve
stabilization. Stabilization of all other parameters was achieved, indicating the
wells had stabilized and the samples were representative of formation water. The
turbidity did not reach an RPD of 10% or less due to inherent turbidity present in
the aquifer. As previously stated, MW -26 is a continuously pumped well.
Continuously pumped wells are pumped on a set schedule per the remediation
plan and are considered sufficiently evacuated to immediately collect a sample.
Due to the continuous pumping of MW-26 turbidity measurements are collected
for informational purposes only. 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 addition, DUSA is currently employing additional
8
N:lRequired Report,IGroundw.ter Quarterly Monitoring Report12010 QJI20JO_Q3 _GW _Report textdoc
well development strategies as required by DRC prior to DRC's consideration of
turbidity variances.
All other field parameters (conductance, pH, redox potential, and temperature) for all
wells were within the required RPD for both quarterly and accelerated sampling.
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 and accelerated samples were received within the required temperature
limit.
3.4.4 Analytical Method Checklist
All analytical methods reported by both laboratories were checked against the required
methods specified in Table 1 of the QAP. Analytical method check results are provided
in Tab G. The review indicated that all quarterly and accelerated samples were analyzed
in accordance with Table 1 of the QAP.
It is recommended that the QAP be improved and updated to include additional
methodologies currently in use by other laboratories certified under the Environmental
Lab Certification Program administered by the Utah Department of Environmental
Quality ("UDEQ") Bureau of Lab Improvement. Potentially, to accommodate ongoing
improvement in technology and methodology, the entire Table 1 and the Chloroform
Investigation Appendix table should be revised to include other currently approved
analytical methods in use by other Utah certified laboratories.
3.4.5 Reporting Limit Evaluation
All analytical method reporting limits reported by both laboratories were checked against
the reporting limits specified in the QAP Table 1. Reporting limit evaluations are
provided in Tab G. All analytes were measured and reported to the required reporting
limits except several sets of routine and accelerated sample results had the reporting limit
raised for at least one 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.

N:lRequired ReportslGroundwater Quarterly Monitoring Report1201 0 Q31201 0_ Q3 _ GW _Report text doc
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.
A deionized ("DI") rinse water sample is no longer used in the groundwater sampling
program as all sampling equipment is dedicated and no rinsate blanks are collected
during this sampling program.
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 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.
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 radiologic sample QC are provided under Tab G. All quarterly
radiologic sample results met the counting error requirement except MW-32. Within
rounding error, the results of MW-32 also approximately met the counting error
requirement. and the duplicate check.
10
N:lRequired Report,IGroundwoter Quarterly Monitoring Report12010 Q312010 _ Q3 _ GW _Report text doc
None of the accelerated samples were analyzed for gross alpha activity because none of
the previous quarter's samples exceeded the GWCL for Gross Alpha.
3.4.9 Other Laboratory QAlQC.
Section 9.2 of the QAP requires that the laboratory's QA/QC 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.
Twelve sets of quarterly sample results (eleven wells and one duplicate) and five setsof
accelerated samples had the reporting limit raised for at least one analyte due to matrix
interference andlor 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 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
11
N:lRequired ReportslGroundwater Quarterly Monitoring Report\20lD Q3\20lD _ Q3 _ GW _Report (eXl doc
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 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
quarterly VOC sample (C10090689) 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 QAIQC 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 July
monthly VOC sample (C10070878) 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 August monthly sample spiked for the MS/MSD pair is a
chloroform well sample. The recoveries for the August monthly MS/MSD pair were high
and indicated 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 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
12
N:lRequired ReportslGroundwater Quarterly Monitoring Report12010 Q31201O_Q3 _GW _Report text.doc
were added to all of the organic analyses as required by the QAP, the data are compliant
with the QAP requirements.
The information from the Laboratory QAlQC Summary Reports indicates that the LCS
recoveries for both the quarterly and accelerated samples were within acceptable
laboratory limits for all LCS compounds except for naphthalene in one analytical batch
for the accelerated sampling. As indicated on Tab G, the LCS recovery for naphthalene
was below the lower acceptance limit and as such indicate a low bias to the sample
results associated with that LCS for naphthalene only. It is important to note that there is
no QAP requirement for LCS recovery assessment.
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. Reagent blanks are blanks created post
sample preparation and are applicable only to samples which do not undergo an
analytical preparation step such as digestion or extraction. For the Mill samples, a
method blank is prepared for all analytical methods, but reagent blanks are created only
for the metals samples. Per the approved QAP, contamination detected in analysis of
reagent blanks (and method blanks) will be used to evaluate any analytical laboratory
contamination of environmental samples. The QAP does not specify the process for
evaluation of reagent or 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. Seventeen analytes were reported in either the method blanks or reagent blanks
from EL. Method and reagent blank results are included in Tab E. In all cases the
method/reagent blank results were less than an order of magnitude relative to the positive
sample results. The detections noted for the reagent/method blanks are significantly lower
than the reporting limits specified in the QAP. Due to the low level of the detections
there is no affect on the quality or usability of the data. 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/reagent blank with each batch and evaluate the results
has been completed as required.
4.0 CORRECTIVE ACTION REPORT
Necessary corrective actions identified during the current monitoring period are described
below, in accordance with Part LF.l.e of the GWDP
4.1 Identification and Definition of the Problem
The problems identified were:
• Turbidity RPDs exceeded 10% for one quarterly sampling well, and two
accelerated sampling wells.
13
N:IRequired ReponslGroundwater Quarterly Monitoring Repon12010 Q312010 _ Q3 _ GW _ Repon t.><t.doc
• Decreased flow rates were noted in two wells during purging. The decreased flow
rates may have resulted in sample collection prior to purging two full casing
volumes from the wells.
4.2 Assignment of Responsibility for Investigating the Problem
The problems have been investigated by the QA Manager.
4.3 Investigation and Determination of Cause of the Problem
Turbidity
Data indicate that it may not be feasible to achieve both a turbidity level of less than 5
NTU and a stabilized turbidity between any two measurements within 10% RPD in every
well. DUSA is currently implementing well redevelopment in response to DRC's letters
dated June 1,2010 and June 24, 2010 to address turbidity variances.
Purge Volumes
Historical data indicate that decreased flow rates occur prior to wells being purged to
dryness. Mill personnel did not purge the wells to dryness and did not recalculate the
time necessary to purge 2 casing volumes which resulted in less than two casing volumes
being purged from two wells prior to sampling.
4.4 Determination of a Corrective Action to Eliminate the Problem
Turbidity
DUSA is currently evaluating the suitability of turbidity, as well as other parameters, in
determining stabilization of monitoring wells. DUSA is implementing a well
redevelopment program. DUSA's letter of July 12,2010 and DRC's response of July 15,
2010 identified the parameters for selecting wells for redevelopment.
Purge Volumes
Mill personnel have been advised that recalculation of purge times is required when flow
rates decrease to ensure that two casing volumes have been purged prior to sampling.
Retraining of sampling personnel has been completed.
4.5 Assigning and Accepting Responsibility for Implementing the Corrective
Action
It will be the responsibility ofthe Director, Compliance and Permitting to implement both
corrective actions.
Turbidity
Development of recommendations and QAP changes to address turbidity have been
submitted and a discussion between DRC and DUSA conducted regarding selection of
wells to be redeveloped. Redevelopment of the wells at the Mill is underway. DUSA is
currently reviewing historical well development data in response to DRC's letters dated
14
N :\Requ ired ReportslGroundwater Quarterly Monitoring Report120 10 Q3120 10_ Q3 _ GW _Report text.doc
June 1,2010 and June 24,2010 and the parameters developed on July 12,2010 and July
15,2010 to determine the list of wells requiring redevelopment.
Purge Volumes
The QA Manager will be responsible for retraining sampling personnel and reviewing
field data sheets as they are completed. Any wells which do not meet the criteria and did
not purge to dryness will be repurged and resampled.
4.6 Implementing the Corrective Action and Evaluating Effectiveness
Implementation of the corrective action for turbidity will follow development of a list of
wells which require redevelopment
Implementation of the corrective action for purge volumes has begun with the retraining
of the sampling staff. Additional reviews will be implemented as samples are collected.
4.7 Verifying That the Corrective Action Has Eliminated the Problem
Verification will occur following review of the well redevelopment data and development
of further actions plans as required.
Verification of the retraining and review processes will be completed after the next
quarter's data collection has begun.
4.8 Assessment of Corrective Actions from Previous Period
The previous Groundwater Monitoring Report (DUSA August 26, 2010) specified a
corrective action for depth to water measurements that were measured properly to the
nearest 0.01 feet, but trailing zeros were not recorded on the field sheets. The corrective
action included advising field staff to record the measurements fully and for DUSA to
implement a data capture system.
As required, field staff were advised of the proper recording of depth to water
measurements. In addition, data were checked as soon as possible after collection to
assure proper recording of depth to water measurements. All measurements were
recorded properly and the corrective action was successful in preventing recurrence.
Furthermore, the data capture system has been modified to accommodate the field forms
in the approved QAP. Implementation of this system will begin during the fourth quarter
2010 sampling event.
Full verification of the data capture implementation portion of the corrective action will
be completed after this quarter's field activities.

REVISED/SUPPLEMENTAL REPORT
Revised Date: 11/04/10
Report Date: 10/13/10
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
October 27,2010 for the correction of the report limit significant figures for cations and to report Manganese and Zinc by
Method 200.8 on sample MW 22. The data presented here shows these corrections.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

REVISED/SUPPLEMENTAL REPORT
Revised Date: 11/08/10
Report Date: 10/14/1 0
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
October 27,2010 for the correction of the report limit significant figures for cations. The data presented here shows this
correction.
COMMENTS
Sample MW 27 was inadvertantly logged for pH instead of TDS analysis at the time of sample receipt. The error was found
after the sample hold time had expired. Energy Laboratories apologizes tor any inconvenience this may have caused.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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: 3rd Quarter Ground Water
Dear Jo Ann Tischler: Lab Set ID: 1009176
American West Analytical Laboratories received 5 sample(s) on 9/10/2010 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.
Thank You, OigilaOy signed by Jose G.

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.

REVISED/SUPPLEMENTAL REPORT
Revised Date: 11/08/10
Report Date: 08/06/1 0
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
October 27, 2010 to report Manganese by Method 200.8 on sample MW 11. The data presented here shows this correction.
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.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (nclt 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: C10071093 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.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

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.
Thank You, K yl e F., gr:-K-=~ ~::;A":t.

Sample Delivery Group: C10081016 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.
SOIUSOLlD 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: C10080767 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S}
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (±2'C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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: August Monthly Ground Water
Dear Jo Ann Tischler: Lab Set 10: 1008533
American West Analytical Laboratories received 3 sample(s) on 8/2712010 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.
Jose Rocha Thank You,
