1.0 INTRODUCTION
This is the Routine Groundwater Monitoring Report, as required under Part J.F. I of State
of Utah Groundwater Discharge PClmit No. UGW370004 (the "GWDP") for the 2nd
quarter of 2010 (the "Qumier") for Denison Mines (USA) Corp's. ("DUSA's") White
Mesa Uranium Mill (the "Mill"). As required under Parts I.E. I, 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.
1.1 GWDP Modifications During the Second Quarter
During the second quarter of2010, the approved January 20, 2010 GWDP was revised on
June 17, 2010. The revision incorporated changes necessary to address Cell 48 at the
Mill. No changes were issued to the Groundwater Compliancc Limits ("GWCLs")
specified in Table 2 or to the groundwater monitoring program described herein.
2.0 GROUNDWATER MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, chlorofonTI 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 2nd quarter included
both quarterly and semi-annual wells. Tablc I 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 Volatile Organic Compounds ("VOCs") due to the loss
of the associated trip blank during shipment. The second date noted for wells MW-I,
MW-3, MW-3A, MW-17, MW-IS, MW-19, MW-70 (duplicate of MW-19), MW-22,
MW-24, and MW-27 reflect the date of the VOC resampling effort. During this
sampling event MW-4, which is a chlorofOlm monitoring well, was inadvertently
sampled for all quarterly analytes. The data, while not compared to GWCLs, are
included in this report for information purposes only. Table 1 also indicates which
sample numbers are associated with the required duplicates.
2.1.2 Accelerated Groundwater Monitoring.
In addition to the routine monitoring referenced above, accelerated sampling was
perfonned, and results reported, for the wells indicated in Table I. The accelerated
sampling frequency, analyte list and well list were detennined based on the lSI quarter
analytical results and are included in Table 2. Table I provides an overview of the wells
sampled for the accelerated 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 Monitol'ing
A requirement was added to the GWDP on March 17, 2008, which required the Mill to
begin quatierly 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,
20 I O. 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") detennines otherwise. Table
I 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.l.c) 2)ii of the GWDP (January 20, 2010/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 and/or piezometers, pursuant
to Part I.E.2 of the GWDP (January 20, 2010/June 17,2010):
• The quarterly groundwater compliance monitoring wells.
• Existing monitoring well MW -4 and all of the temporary chlorofonn investigation
wells.
• Piezometers -P-I, P-2, P-3, P-4 and P-S.
• Nitrate monitoring wells.
• In addition to the above, depth to water measurements are routinely observed 111
conjunction with sampling events for all wells sampled during quarterly and
accelerated efforts, regardless of the sampling purpose.
2
All water levels used for groundwater contour mapping were measured and recorded
within 5 calendar days of each other except TW 4-26 as indicated by the measurement
dates in the summary sheet under Tab D. TW4-26 was installed after the quarterly water
levels were measured. Water level data for TW 4-26 was recorded when the well was
first sampled in June 2010.
2.2 Field Data
Attached under Tab B are copies of all field data sheets recorded in association with the
routine quarterly and semi-annual effort for the groundwater compliance monitoring
wells referred to in paragraph 2.1.1, above. Sampling dates are listed in Table I. 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
May and June 2010 accelerated monitoring and sampling efforts.
2.3 Laboratory Results -Routine 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 I lists the dates when analytical results were repOlted to the Quality Assurance
("QA") Manager for each well.
Results from analysis of samples collected for the 2nd Qumter under the OWDP (i.e., all
regular quarterly and semi-annual 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 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 I.
Copies of laboratory QAlQuality Control ("QC") Summaries are included with the
reported data under their corresponding Tabs.

2.3.2 Regulatory I<'ramcwork aud Groundwater Background
As previously stated in Section 1.1, during the second quarter 20 I 0, a revision was issued
to the approved January 20, 2010 GWDP on June 17,2010. The revision incorporated
changes necessary to address Cell 48 at the Mill. No changes were issued to the GWCLs
specified in Table 2 or to the groundwater monitoring program described herein. Under
the GWDP (January 20, 2010/June 17,2010), background groundwater quality has been
detelmined 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 2nd
Quarter monitoring period.
Exceedances of the January 21,2010 GWCLs as reported in the 1st quarter (January
through March) report determined the accelerated monitoring program implemented
during this quarter.
Exceedances of the GWCLs for the 2nd quarter (April through June) of 201 ° are listed in
Table 2 for sampling required under the revised GWDP (January 20, 201 O/June 17,
2010).
It should be noted, however, that, because the GWCLs have been set at the mean plus
second standard deviation, or the equivalent, un-impacted groundwater would nonnally
be expected to exceed the GWCLs approximately 2.5% of the time. Therefore,
exceedances are expected in approximately 2.5% of all sample results, and do not
necessarily represent impacts to groundwater from Mill operations.
2.4 Laboratory Results -Accelerated Monitoring
2.4.1 Copy of Laboratory Results
The analytical results for the accelerated monitoring of the various constituents in certain
monitoring wells for the quarter are provided at Tab F.
Accelerated sampling which was required for 2nd quarter 2010 under the revised GWDP
(January 20, 2010) was perfOlmed for wells MW-II, MW-14, MW-26, MW-30, and
MW -31. The exceedances reported in the accelerated samples are discussed in Section
2.4.3 below.
2.4.2 Regulatory Framework and Groundwatcr 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.I of the
previous GWDP ceased effective on January 20,2010, and the effect of the issuance of
thc revised GWDP was to create a "clean slate" for all constituents in all wells going
forward.
4
This means that accelerated monitoring during the 2nd quarter was required under the
revised GWDP for only those constituents that exceeded the GWCLs in I st quarter of
2010.
2.4.3 Compliance Status
Analytes which have exceeded the GWCLs set forth in the GWDP for both the first and
second quarter are summarized in Table 2. The analytes which exceeded their respective
GWCLs during the second quarter 20 10 will be sampled on an accelerated schedule as
noted in Table 2. Analytes which exceeded their respective GWCLs during the first
quarter 2010 are currently sampled on an accelerated schedule. A review of the
accelerated data collected during second quarter 20 I 0, indicate that the analytes discussed
below have exceeded their respective GWCLs for two consecutive sampling periods as
reported in DUSA's letter to DRC on July 23,2010.
• Manganese in MW -II slightly exceeded its GWCL during both the Q I and Q2,
2010 sampling events. However, this analyte has dropped below the GWCL for
the subsequent May and June, 2010 monthly monitoring periods.
• Field pH has been slightly outside (slightly lower than) the GWCL in MW-14 for
both the Q I and Q2 sampling events. As discussed in previous qualterly
groundwater sampling reports, the background levels and GWCLs for pH were
established based on eight or more quarters of laboratory data, which are
historically higher than field data due to effects from the evolution of carbon
dioxide, and subsequent increase in pH from field to lab. DUSA intends to
propose revised GWCLs for pH in the near future, based on a statistical analysis
of actual field data, which is expected to result in somewhat lower GWCLs for pH
in most wells. Although monitored results of field pH from MW -14 were slightly
lower than the GWCL for the Q I and Q2 quarterly monitoring periods, they
returned to within the GWCL range for the May and June monthly sampling
periods.
• Nitrate and uranium in MW-26 have exceeded their respective GWCLs in both
the Q I and Q2 monitoring periods but have returned to within their respective
GWCLs for both the May and June monthly monitoring periods. Chloroform in
MW-26 has exceeded its GWCL for the QI and Q2 quarterly as well as the May
and June monthly monitoring periods. MW-26 is used as a pumping well for the
ongoing chlorofonn capture program and is expected to yield increased
concentrations of chlorofonn. Also, as stated in the September 2009 Statement of
Basis (page 23) in support of the January 20, 2010 revisions to the GWDP, "[ilt
should be noted that, because MW-26 is a pumping well for chloroform removal,
concentrations of all constituents in that well are subject to potential variation
over time as a result of the pumping activity. This will be taken into account by
the Executive Secretary in detennining compliance for this well."
5
• Nitrate and chloride in MW-30 and MW-31 and other monitoring wells at the site
are the subject of an ongoing investigation. In the December 30, 2009 Nitrate
Contamination Investigation Report, prepared by Intera, Inc., Intera has
concluded that the elevated nitrate and chloride concentrations observed at the
Mill resulted from historic off-site sources unrelated to the Mill's operations.
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. As previously stated, well TW4-26 was
installed after the completion of the quarterly water level measurements. Water level
data for TW4-26 was recorded when the well was first sampled event in June 2010. 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 weIls 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 QA/QC review to con finn compliance of the
monitoring program with requirements of the White Mesa Uranium Mill Groundwater
Monitoring Quality Assurance Plan ("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 QA/QC are discussed in
Sections 3.4.4 through 3.4.9 below.
The Analytical Laboratories have provided summary reports of the analytical QA/QC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The analytical laboratory QA/QC 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
QA/QC infOlmation are provided under Tab G and discussed in Section 3.4, below.
6
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 routine quarterly sampling as indicated in
Table 1. As previously stated, some locations were resampled due to the loss of the trip
blank. MW -70 (duplicate of MW -19) 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 pennit-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. As noted in Section 2.1.1, several wells were resampled due to the
loss of a trip blank during shipping. To assure that all QAP required QC samples were
collected, the wells were resampled and submitted with the appropriate QC samples.
One trip blank per month was provided by EL and returned and analyzed with the
accelerated monitoring samples.
Four trip blanks were provided by A WAL 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.
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 QA/QC 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 OWDP for routine quarterly samples and background well
samples for the period were perfonned. In addition, all accelerated sampling required for
this quarter, as identified in Table 2, was performed.
7
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 QAIQC evaluation, a
receipt temperature check, a holding time check, an analytical method check, a reporting
limit check, a trip blank check, a QAIQC evaluation of routine sample duplicates, a
QAIQC evaluation of accelerated sample duplicates, a gross alpha counting error
evaluation and a review of each laboratory's reported QAIQC 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 QA/QC 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
infollnation: 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 except TW 4-26 were
conducted within a five-day period. As previously stated, TW 4-26 was installed after the
completion of the quarterly water level measurements were completed. The water level
for TW4-26 was measured when the well was first sampled in June 2010. The results of
this quatter's review are provided in Tab G.
Based upon this review, all quarterly sampled locations confollned to the QAP
requirement to evacuate two well casing volumes before sampling except for MW -3A,
MW-12, MW-20, MW-23, and MW-24. In all cases these wells were evacuated to
dryness before two casing volumes could be pumped. 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 except MW-14, MW-IS, MW-18 (resample), MW-19 (resample), and MW-70
(duplicate of MW -19). In all cases the depth to water was measured to the nearest 0.0 I
feet, however, the "trailing zero" which represents the hundredths place was not recorded
during the field activities. In other words, the depth to water measurement for MW -14
was 103.60 feet, however, the field personnel only recorded 103.6 feet. The data are
acceptable and usable with no limitations.
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-14 during both the May and June sampling events. As
previously stated, there is no affect on the usability or validity of the data due to the
8
omission of the zeros. Corrective actions are described in Section 4.
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 S 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 S NTU prior to sampling. As such the noted observations regarding turbidity
measurements greater than S NTU below are included for information purposes only.
• Turbidity measurements were less than S NTU for all of the quarterly and semi-
annual wells except MW-I, MW-S, MW-12, MW-IS, MW-17 (resample), MW-
22, MW-2S, MW-29, and MW-32. MW-12 was purged to dryness before a
turbidity measurement less than S NTU could be achieved. 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-3A
(resample), MW-I 7 (resample), MW-18, MW-20, MW-25 and MW-29. MW-3A
was purged to dryness before a turbidity RPD less than less than 10 percent could
be achieved. 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 cUiTently reviewing historical well
development data in response to DRC's letters dated June 1,2010 and June 24,
20 I 0 to detetmine 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 wells
except MW-I 1 and MW-26 in the June sampling event. MW-26 is a continuously
pumped well and the field parameters are used for infotmational purposes only
and not as an indication of stabilization. As previously stated, the QAP does not
require that turbidity be less than S NTU. Turbidity measurements prior to
sampling were within a 10% RPD for all accelerated sampling wells except MW-
26. 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 reviewing historical
well development data in response to DRC's letters dated June I, 2010 and June
24,2010 to determine additional 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 I 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 were reviewed to confirm compliance with the QAP requirement
in QAP Table I that samples be received at 6°C or lower. Sample reeeipt temperature
checks are provided under Tab G. All 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 I 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 I and the Chloroform
Investigation Appendix table should be revised to include other currently approved
analytical methods in use by other Utah celtified 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 andlor sample dilution as noted
in Section 3.4.9. In all cases the reported value for the analyte was higher than the
increased detection limit.
3.4.6 Trip Blank Evaluation
All trip blank results were reviewed to identify any blank contamination. Trip blank
evaluations are provided in Tab G. All trip blank results associated with both the
quarterly and accelerated samples were less than detection level for all VOCs.
A deionized ("DI") rinse water is no longer used in the groundwater sampling program;
however, a DI rinse water sample was inadvertently collected. As previously stated,
10
several VOC samples were unusable due to the loss of the associated trip blank. The 0 I
rinse water sample was in that shipment. Since the 01 rinse water was not required the
VOC fraction was not recollected. The DI rinse water data are included for information
purposes only.
3.4.7 QA/QC Evaluatiou 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 arc 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 except for
molybdenum in the duplicate pair MW-32/MW-65 and zinc in duplicate pair MW-
19/MW -70. In all cases these results are less than 5 times the required reporting limit and
the RPDs greater than 20 percent are acceptable. Results of the RPD test are provided
under Tab G.
All duplicate results were within a 20% RPD in the accelerated samples except for nitrate
in the duplicate pair MW-26/MW-65. These results are less than 5 times the required
reporting limit and the RPDs greater than 20 are acceptable. 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 eounting variance that is equal to or less
than 20% of the reported activity concentration. An error term may be greater than 20%
of the repOlted activity concentration when the sum of the aetivity 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 routine radiologic sample QC are provided under Tab G. All routine
radiologic sample results except MW-4, MW-23, MW-27, and MW-28, met the counting
error requirement. Within rounding error, the results of MW-4, MW-23, MW-27, and
MW-28 also met the counting error requirement. Additionally, as discussed in Section
11
2.1, above, sampling of MW -4 was not required for this constituent. Analytical data, and
data QC testing for MW-4 has been provided for information purposes only.
None of the second qumter accelerated samples were analyzed for gross alpha activity
because none of the first quarter samples exceeded the GWCL for Gross Alpha.
3.4.9 Other Laboratory QA/QC.
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 cOtTect
and complete, (2) analysis information is CotTect 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 QA/QC 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. DUSA required
A W AL to reissue earlier reports to address the reporting limit for the Method Blank
samples which was incorrectly reported in the original transmittal. The carat C')
associated with some of the A W AL Method Blanks indicates that the data had been
previously reported.
Twenty eight sets of routine sample results (25 wells, two duplicates and the DI sample
blank) 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. The OJ sample blank had a raised reporting limit for
bicarbonate and it was noted by the laboratory that bicarbonate was detected in the
method blank. As previously stated the DI sample blank is no longer needed for the
!,Yfoundwater program and was inadvertently collected. As such there is no affect on the
groundwater sample data usability.
Eight sets of accelerated sample results (6 wells and two duplicates) 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 repotting limit.
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:
12
• 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 Swnmary
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 paekages 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 infOlmation from the Laboratory QA/QC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all routine 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. Furthennore,
the VOC samples and one of the metals samples (CI0050678) 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 QA/QC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all accelerated samples were within
acceptable laboratory limits for all reh'Ulated compounds.
The QAP specifies that surrogate compounds shall be employed for all organic analyses
but the QAP does not specify acceptance limits for surrogatc recoveries. The analytical
data associated with the routine quarterly sampling met the requirement specified in the
QAP. The infolmation from the Laboratory QA/QC Summary Reports indicates that the
surrogate recoveries for all routine qumterly samples were within acceptable laboratory
limits for all surrogate compounds except as indicated in Tab G. In all instances the
sun'ogate recoveries outside of acceptance limits were above the upper limit or had a high
13
recovery, indicating a high bias to the individual sample results. A high bias means that
reported results for this analyte will tend to be more conservative or higher than it
actually is. The sample results associated with the high surrogate recoveries were all
nondetect and as such there is no affect on the quality or usability of the data. 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 QAIQC Summary Reports indicates that the
surrogate recoveries for all accelerated samples were within acceptable laboratory limits
for all surrogate compounds except for one trip blank and one sample as indicated in Tab
G. The surrogate recovery for MW -65 was above the upper acceptance limit indicating a
high bias to the sample results which results in a more conservative (higher) reported
value. The surrogate recovery for the trip blank was low and indicates a low bias to the
trip blank sample only and the trip blank had no reported detections. 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.
The information from the Laboratory QAIQC Summary Reports indicates that the LCS
recoveries for both the routine and accelerated samples were within acceptable laboratory
limits for all LCS compounds except for acetone and methyl ethyl ketone ("MEK") in
one analytical batch. As indicated on Tab G, the LCS recoveries were above the upper
acceptance limit and as such indicate a high bias to the sample results associated with that
LCS. A high bias to the sample results is a more conservative approach to site
assessment. It is important to note that there is no QAP requirement for LCS recovery
assessment.
4.0 CORRECTIVE ACTION REPORT
Necessary corrective actions identified during the current monitoring period are described
below, in accordance with Part I.F.l.e of the GWDP
4.1 Identification and Definition of the Problem
The problems identified were:
• Turbidity RPDs exceeded 10% for five quarterly sampling wells, and one
accelerated sampling well.
• Depth to water measurements were measured properly to the nearest 0.01 feet,
however, trailing zeros were not recorded on the field sheets.
4.2 Assignment of Responsibility for Investigating the Problem
The problems have been investigated by the QA Manager.
14
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 reviewing historical well development data in response to
DRC's letters dated June I, 2010 and June 24, 2010 to detennine additional well
development strategies to address turbidity variances. Specifically, during ongoing
discussions and cOlTespondence with DRC, DUSA has agreed to evaluate whether the
wells with reCU11'ent instability have been properly developed and to establish a list of
wells which will be redeveloped.
Depth to Water
Based on discussions with Mill personnel, depth to water measurements were measured
properly to the nearest 0.01 feet, however, trailing zeros were not recorded on the field
sheets.
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
detennining stabilization of monitoring wells. DUSA is preparing a summary of
historical well development information for existing groundwater wells and will make a
recommendation to DRC regarding which wells should be redeveloped. DUSA's letter
of July 12, 2010 and DRC's response of July 15, 2010 identified the parameters for
selecting wells for redevelopment.
Depth to Water
Mill personnel have been advised that depth to water must be recorded to the nearest 0.0 I
feet. If the measurement is a whole integer number or the final measurement number is
zero, it must be recorded on the field sheet to the nearest 0.01. In addition, DUSA has
purchased a data capture system that will be employed for recording field data. The data
system will allow the real-time recording of field data on hardcopy fOnTIS while digitally
storing the information as it is collected. The data collection system and revised field
forms will not allow incomplete data collection such as recording depth to water without
all decimal places recorded. To address the implementation of the data capture, DUSA
has requested the use of new field fonns in the revised QAP. DUSA will proceed with
the implementation of that step upon revision of the fonns to address DRC comments and
subsequent DRC approval of the QAP revision.
4.5 Assigning and Accepting Responsibility fOl' Implementing the Corrective
Action
It will be the responsibility of the Director, Compliance and Pennitting to implement both
corrective actions.
15
Turbidity
Development of recommendations and QAP changes to address turbidity have been
submitted and discussion between DRC and DUSA completed. Determination of wells
to be redeveloped is underway. DUSA is currently reviewing historical well
development data in response to ORe's letters dated June 1,2010 and June 24, 2010 and
the parameters developed on July 12, 2010 and July 15,2010 to detennine a list of wells
requiring redevelopment.
Depth to Water
Development of recommendations and QAP changes to address the incomplete recording
of correctly measured field data has been started. DUSA is cutTently revising the field
fonns to address DRC comments. Upon completion of the field fonn modifications, and
DRC approval of the QAP DUSA will completely implement the field data capture
program.
4.6 Implementing the Corrective Action and Evalnating Effectiveness
Implementation of the corrective action for turbidity and depth to water will follow
development and DRC approval of an action plan.
4.7 Verifying That the Corrective Action Has Eliminated the Problem
Verification will occur following DRC review of the proposed well redevelopment list
and implementation of redevelopment as required.
Verification of depth to water measurements will begin next quarter during the field
activities to assure that measurements are recorded completely prior to the
implementation of the digital data capture program. Full verification of the field data
capture program will begin after the program has been implemented.
5.0 TIME CONCENTRATION PLOTS
Time concentration plots for each monitoring well for the following constituents:
chloride, fluoride, sulfate, and uranium, are included under Tab 1.
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") fonnat
from the AWAL data. A copy of the transmittal e-mail is included under Tab J.

Sample Delivery Group: C10040828 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±20C)
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.

CLIENT: Denison Mines USA Corp
Project: Semi Annual Ground Water Sampling Report Date: 06/03/10
Sample Delivery Group: C10041 01 0 CASE NARRATIVE
ORIGINAL SAMPLE SUBMIITAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2'C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

CLIENT: Denison Mines USA Corp
Project: Semi Annual Ground Water Report Date: 06/03/10
Sample Delivery Group: C10050254 CASE NARRATIVE
LABORATORY COMMENTS
Per Ryan Palmer 05/11/10 cancel TDS and pH analyses on sample MW 3 due to receiving sample with insufficient hold time
remaining for analysis. vac analysis cancelled on all samples due to receiving Trip Blank broken.
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
AI! samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

CLIENT: Denison Mines USA Corp
Project: Semi Annual Ground Water Resample Report Date: 06/03/10
Sample Delivery Group: C10050464 CASE NARRATIVE
LABORATORY COMMENTS
The samples on this workorder are resamples from workorder C1 0050254. The original samples were cancelled due to
insufficient hold time and receiving Trip Blanks broken.
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
Subcon1racting 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: Semi Annual Ground Water (Resample) Report Date: 06/04/10
Sample Delivery Group: C10050678 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 jf 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 waler 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 refiects 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: C10060067 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITIAL(S}
AI! 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 al! 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: Semi Annual Ground Water I 2nd Quarter
Dear Jo Ann Tischler: Lab Set lD: 1004582
American West Analytical Laboratories received 8 sample(s) on 4/30/2010 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 fi·ee to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratolY 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 repolting limit must not be confused
with any regulatory limit.

RE: AWAL Lab Set 1004582 -Semi Annual Ground Water-2nd Quarter
Please do run the trip blanks for THF. I had discussed this with Melanie and I<yle in February and March, and they seem
to have forgotten to tell you.
It's il requirement of our QAP that you send blank bottles to the Mill, and run blanks for the same volatile parameters as
you analyze.

Jo Ann,
With the samples I received today, there was a set of Trip Blanks. It was listed on the chain of custody, but did not have
any analysis checi<ed. We will go ahead and run these for THF along with the other samples. If you would prefer us not
to run the Trip Blank, please let me Imow as soon as possible and we will stop the analysis and remove it from the chain
of custody.
Thank You,

RE: Semi Annual Ground Water-2nd Quarter
Dear Jo Ann Tischler:
Lab Set ID: 1004464
American West Analytical Laboratories received 10 sample( s) on 4/23/20 10 for the
analyses presented in the following report.
AIl 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 calI.
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.

RE: Semi Annual Ground Water
Dear Jo Ann Tischler: Lab Set ID: 1006029
American West Analytical Laboratories received 2 sample(s) on 6/2/20 10 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted othelwise. 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 fi'ee 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.
Thank You,

CASE NARRATIVE
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
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: May Monthly Ground Water
Dear Jo Ann Tischler: Lab Set ID: 1005461
American West Analytical Laboratories received 2 sample(s) on 5/26/2010 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 "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.
This is a revision to a report originally issued 5/27/2010. Pages 1 and 6 have been
Jose Rocha revised.

Sample Delivery Group: Cl0060784 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.

RE: Monthly Ground Water Sampling
Dear Jo Ann Tischler: Lab Set 10: 1006358
American West Analytical Laboratories received 2 sample( s) on 6117/2010 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 "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 "RepOlting 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.
Thank You,
