1.0 INTRODUCTION
This is the Routine Groundwater Monitoring Report, as required under Part I.F.1 of State
of Utah Groundwater Discharge Permit No. UGW370004 (the "GWDP") for the second
quarter of 2012 (the "quarter") for Energy Fuels Resources (USA) Inc's. ("EFR's")
(formerly Denison Mines (USA) Corp.'s). White Mesa Uranium Mill (the "Mill"). As
required under Parts I.E. 1 , I.E.2 and I.E.5 of the GWDP this Report includes all recorded
field measurements and laboratory analyses for well monitoring conducted during the
quarter.
1.1 Quality Assurance Plan Modifications during the Quarter
During the first and second quarter of 2012, Revision 6 of the approved Quality
Assurance Plan ("QAP"), dated March 22, 2010, was revised on March 26, 2012
(Revision 7.0), May 25,2012 (Revision 7.1) and June 6, 2012 (Revision 7.2). Revision
7.0, dated March 26, 2012, incorporated changes requested by Division of Radiation
Control '("DRC") in correspondence dated February 7, 2012. The changes were
requested to address field sampling procedures for low yield wells consistent with U.S.
Environmental Protection Agency ("EPA") guidance documents. EFR submitted
Revision 7.0 of the QAP on March 26, 2012. Revision 7.1 was submitted on May 25,
2012 to address minor changes to Revision 7.0 noted by DRC. Revision 7.1 was
approved by DRC in correspondence dated May 30, 2012. EFR noted on June 6, 2012
that there were typographical errors in Revision 7.1 that interfered with field operations
and submitted Revision 7.2 on June 6, 2012 to correct these typographical errors. DRC
approved Revision 7.2 on June 7, 2012.
Samples were collected during the second quarter 2012 using the procedures contained in
Revisions 6.0 and 7.1 (as corrected in Revision 7.2) of the QAP. Samples collected prior
to May 30, 2012 were purged and sampled in accordance with the procedures in Revision
6 of the QAP. Samples collected after May 30, 2012 were purged and sampled in
accordance with Revision 7.1 (as corrected in Revision 7.2) of the QAP.
2.0 GROUNDWATER MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, chloroform contaminant investigation wells and nitrate contaminant investigation
wells is attached under Tab A. Groundwater samples and measurements were taken
during this reporting period (April through June), as discussed in the remainder of this
section.
1
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
2.1.1 Groundwater Compliance Monitoring
Groundwater samples and field measurements collected during the quarter included
quarterly, semi-annual and accelerated monitoring. Accelerated monitoring is discussed
below in Section 2.1.2. In the narrative in Sections 2 and 3 of this quarterly report,
samples classified as being collected quarterly include those wells which are sampled
every quarter and the wells sampled semi-annually. Wells which are sampled routinely
every quarter and semi-annually were analyzed for the parameters listed in Table 2 and
Part I.E.1.c) 2) ii of the GWDP dated July 14,2011.
Table 1 of this report provides an overview of all wells sampled during the current
period, along with the required sampling frequency applicable to each well during the
current monitoring period, the date samples were collected from each well, and the
date(s) analytical data were received from the contract laboratory(ies). Table 1 also
indicates which sample numbers are associated with the required duplicates. During this
quarter, two wells and one duplicate were resampled due to poor duplicate agreement and
a missed holding time. The following is a list of wells which were resampled:
• MW -26 and MW -65 (duplicate of MW -26) were resampled for volatile organic
compounds ("VOCs") due to a laboratory issue which resulted in poor agreement
between the sample (MW-26) and the duplicate (MW-65).
• MW -31 was resampled for total dissolved solids ("TDS") due to the laboratory
missing the holding time.
Table 1 has also been color-coded to reflect which of the QAP revisions was in effect at
the time of sampling.
2.1.2 Accelerated Groundwater Monitoring.
Accelerated monthly sampling was also performed (quarterly wells accelerated to
monthly), and results reported, for the wells indicated in Table 1. The accelerated
sampling frequency, analyte list and well list were determined based on the previous
analytical results as shown in Table 2.
Table 1 provides an overview of the wells sampled for the accelerated monthly program
along with the routine sampling frequency as well as the accelerated sampling frequency,
the date samples were collected from each well, the associated duplicates and the date( s)
which analytical data were received from the contract laboratory(ies).
2.1.3 Background Well Monitoring
A requirement was added to the GWDP on February 15,2011, which required the Mill to
begin quarterly sampling of wells MW-35, MW-36 and MW-37 to develop eight quarters
of background data. MW-35, which was installed in the third quarter 2010, has been
sampled quarterly since the fourth quarter of 2010. MW-36 and MW-37, which were
installed during the second quarter of 2011, were sampled for the first time during the
2
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
second quarter of 2011. Quarterly samples will continue to be collected until 8 quarters
of data are available to complete the background report as required by the GWDP.
2.1.4 Parameters Analyzed
All routine quarterly and semi-annual groundwater monitoring samples were analyzed for
the parameters listed in Table 2 and Part I.E.1.c) 2) ii of the GWDP dated July 14, 2011.
The accelerated monitoring samples were analyzed for a more limited and specific
parameter list as shown in Table 2.
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 GWD P dated February 15, 2011:
• The quarterly groundwater compliance monitoring wells (including, MW-34).
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-l, P-2, P-3, P-4 and P-5.
• Nitrate monitoring wells.
• The DR piezometers which were installed during the Southwest Hydrogeologic
Investigation.
• 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 (sampled in May) for the groundwater compliance monitoring wells
referred to in paragraph 2.1.1, above. Sampling dates are listed in Table 1. Tab B also
includes field data sheets for general monitoring wells MW-20 and MW-22, and all
resampling efforts conducted during this quarter.
Attached under Tab C are copies of all field data sheets recorded in association with the
April and June 2012 accelerated monitoring and sampling efforts.

2.3 Laboratory Results -Quarterly Sampling
2.3.1 Copy of Laboratory Results
All analytical results are provided by one of the Mill's two contract analytical
laboratories EL or 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 under the GWDP (i.e., all regular quarterly
and semi-annual samples are provided in Tab E. Also included under Tab E are the
results of analyses for duplicate samples as identified in Table 1.
The laboratory report dates for samples collected for the April and June accelerated
sampling (i.e. quarterly accelerated to monthly) are provided in Table 1. Results from
analysis of samples collected for the April and June accelerated sampling (i.e. quarterly
accelerated to monthly) are provided in Tab F. Also included under Tab F are the results
of analyses for duplicate samples for this sampling effort, as identified in Table 1.
Copies of laboratory QAlQuality Control ("QC") Summaries are included with the
reported data under their corresponding Tabs.
2.3.2 Regulatory Framework and Groundwater Background
Under the GWDP dated July 14, 2011, background groundwater quality has been
determined on a well-by-well basis, as defined by the mean plus second standard
deviation concentration or the equivalent. GWCLs that reflect this background
groundwater quality have been set for all monitoring wells except MW-35. It is
important to note that the GWDP dated February 15,2011 also set GWCLs for MW-35.
The GWCLs for MW-35 have been set at one-quarter of the Utah Groundwater Quality
Standard ("GWQS"), pending determination of background for the well, and are not
based on eight quarters of data from that well. A background report for MW-35 will be
completed after the collection of eight quarters of data.
Exceedances of the GWCLs determined the accelerated monthly monitoring program
implemented during this quarter as noted in Tables 1 and 2.
Exceedances of the GWCLs for this quarter are listed in Table 2 for sampling required
under the revised GWDP July 14, 2011. Table 3 shows the accelerated sampling
program which started in the second quarter 2010 and shows the results and frequency of
the accelerated sampling conducted since that time.
4
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
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 a revised GWDP on January 20, 2010, which sets revised
GWCLs, all requirements to perform accelerated monitoring under Part I.G.1 of the
previous GWDP ceased effective on January 20, 2010, and the effect of the issuance of
the revised GWDP was to create a "clean slate" for all constituents in all wells going
forward.
This means that accelerated monitoring during this quarter was required under the revised
GWDP for only those constituents that exceeded the GWCLs since January 20,2010.
2.4.3 Compliance Status
Analytes which have exceeded the GWCLs set forth in the GWDP are summarized in
Table 2. The analytes which exceeded their respective GWCLs during the quarter will be
sampled on an accelerated schedule as noted in Table 2. Analytes which exceeded their
respective GWCLs during 2010 are currently sampled on an accelerated schedule. A
review of the accelerated data collected during the quarter indicate that several anal ytes
have exceeded their respective GWCLs for two consecutive sampling periods as reported
in EFR's (submitted under Denison letterhead) letter to DRC on July 27, 2012. Table 3
summarizes the results of the accelerated sampling program from first quarter 2010
through second quarter 2012.
Part I.G.1 c) of the GWDP states, with respect to exceedances of GWCLs, "that the
Permittee shall prepare and submit within 30 calendar days to the Executive Secretary a
plan and a time schedule for assessment of the sources, extent and potential dispersion of
the contamination, and an evaluation of potential remedial action to restore and maintain
groundwater quality to insure that Permit limits will not be exceeded at the compliance
monitoring point and that DMT or BAT will be reestablished." EFR submitted an
exceedance notice on July 27, 2012 for the second quarter 2012 results. The summary in
the Exceedance Notice includes, for each exceedance, a brief discussion of whether such
a plan and schedule is required at this time in light of other actions currently being
undertaken by EFR, as determined by DRC Staff and stated in teleconferences with EFR
5
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
on April 27 and May 2, 2011 and the Stipulated Consent Agreement ("SCA") dated July
12,2012.
2.5 Depth to Groundwater and Water Table Contour Map
As stated above, a listing of groundwater level readings for the quarter (shown as depth to
groundwater in feet) is included under Tab D. The data from Tab D has been interpreted
(kriged) and plotted in a water table contour map, provided under Tab H.
The water table contour map provides the location and identity of all of the wells and
piezometers for which depth to groundwater is recorded. The groundwater elevation at
each well and piezometer, measured in feet above mean sea level, and isocontour lines to
delineate groundwater flow directions observed during the quarter's sampling event are
displayed on the map.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The Mill QA Manager performed a QAlQC review to confirm compliance of the
monitoring program with requirements of the QAPs As noted in Section 1.1 and
identified on Table 1, there were multiple QAPs in effect during this sampling period. As
required in the QAPs, data QA includes preparation and analysis of QC samples in the
field, review of field procedures, an analyte completeness review, and quality control
review of laboratory data methods and data. Identification of field QC samples collected
and analyzed is provided in Section 3.1. Discussion of adherence to Mill sampling
Standard Operating Procedures ("SOPs") is provided in Section 3.2. Analytical
completeness review results are provided in Section 3.3. The steps and tests applied to
check laboratory data QAlQC are discussed in Sections 3.4.4 through 3.4.10 below.
The Analytical Laboratories have provided summary reports of the analytical QAlQC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The analytical laboratory QAlQC Summary Reports, including copies of the Mill's Chain
of Custody and Analytical Request Record forms for each set of Analytical Results,
follow the analytical results under Tabs E and F. Results of review of the laboratory
QAlQC information are provided under Tab G and discussed in Section 3.4, below.
3.1 Field QC Samples
The following field QC samples were generated by Mill personnel and submitted to the
analytical laboratory in order to assess the quality of data resulting from the field
sampling program:
Two duplicate samples were collected during quarterly sampling as indicated in Table 1.
The QC samples were sent blind to the analytical laboratory and analyzed for the same
parameters as permit-required samples.
6
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
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
anal yzed for the same accelerated parameters as the parent sample.
Seven 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.
Six trip blanks were provided by AWAL and returned and analyzed with the quarterly
monitoring samples.
One trip blank was provided by A W AL and returned and analyzed with the April
accelerated monitoring samples. Accelerated monthly monitoring was no longer required
for tetrahydrofuran ("THF") in MW-11 after April 2012, per DRC correspondence dated
April 16, 2012, therefore, an accelerated monthly sample and the associated trip blank
were not necessary in June 2012.
Rinsate samples were not collected during the quarter because all equipment used during
sample collection was dedicated and did not require decontamination. All wells except
MW-20 and MW-37 have dedicated pumps for purging and sampling and as such no
rinsate blanks samples are required. MW-20 and MW-37 were sampled with a
disposable bailer and no rinsate blank was required. A deionized field blank (DIFB) was
not required because equipment decontamination was not required and deionized water
was not used during this sampling event.
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 QAPs were being adhered
to and that the SOP's were implemented, except as described below.
3.3 Analyte Completeness Review
All analyses required by the GWDP for the quarterly and semi-annual wells were
performed. The accelerated sampling for the semi -annual wells (semi -annual to
quarterly) was completed as required by the GWDP and as shown in Tables 2 and 3. The
accelerated quarterly sampling (quarterly to monthly) required for this quarter, as shown
in Tables 2 and 3, was performed as required.
3.4 Data Validation
The QAPs 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
7
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
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 for wells
sampled prior to May 30, 2012. Stability of field parameters and well sampling
techniques for wells sampled after May 30, 2012 are dependent on the purging technique
employed. 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.
Wells Sampled Prior to May 30, 2012 under Revision 6 of the QAP
Wells sampled prior to May 30, 2012, include the April monthly accelerated monitoring
and all quarterly and semi-annual monitoring wells except MW-20.
Based upon the review of the Field Data Sheets, all quarterly and semi-annually sampled
locations which were sampled prior to May 30, 2012 conformed to the QAP, Revision 6,
requirement to evacuate two well casing volumes before sampling except for MW -03A,
MW-12, and MW-37. These wells were evacuated to dryness before two casing volumes
could be pumped. MW -23 and MW -24 were purged dry after 2 casing volumes were
removed. MW-37 has insufficient water to purge using a pump. Due to the small volume
of water present, this well is purged and sampled using a disposable bailer.
Additionally, two casing volumes were not purged from MW -26, prior to sampling
because MW-26 is a continuously pumped well. If a well is continuously pumped, it is
pumped on a set schedule per the remediation plan and is considered sufficiently
evacuated to immediately collect a sample; however, if a pumping well has been out of
service for 48 hours or more, DUSA will follow the purging requirements outlined in
Attachment 2-3 of the QAP.
All April accelerated sampled locations conformed to the QAP, Revision 6, requirement
to evacuate two well casing volumes before sampling.
The review of the field sheets for compliance with QAP, Revision 6, dated March 22,
2010 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%
8
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
Relative Percent Difference ("RPD") over at least 2 consecutive measurements. The
QAP, Revision 6, states that turbidity should be less than 5 Nephlometric Turbidity Units
("NTU") prior to sampling unless the well is characterized by water that has a higher
turbidity. The QAP does not require that turbidity measurements be less than 5 NTU
prior to sampling. As such the noted observations regarding turbidity measurements
greater than 5 NTU below are included for information purposes only.
• Turbidity measurements were less than 5 NTU for all of the quarterly and semi-
annual wells sampled prior to May 30, 2012 except MW-01, MW-12, MW-17,
MW-22. MW-23, MW-26, MW-29, MW-32 and MW-37. Per the QAP, Revision
6, Section 6.2.7 d) (v) Turbidity measurements prior to sampling were within a
10% RPD for all quarterly and semi-annual wells collected prior to May 30, 2012.
• Turbidity measurements were less than 5 NTU for all of the April accelerated
sampling wells except MW-25 and MW-31. 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
All other field parameters (conductance, pH, redox potential, and temperature) for all
wells sampled prior to May 30, 2012 were within the required RPD for the quarterly,
semi -annual and accelerated sampling.
Wells Sampled After May 30, 2012 under Revision 7.1 of the QAP (As corrected in
Revision 7.2)
Wells sampled after to May 30, 2012, include those wells which were sampled during the
June monthly accelerated monitoring event and MW-20.
Based upon the review of the Field Data Sheets, MW-20 conformed to the QAP,
Revision 7.1 (as corrected in Revision 7.2) requirement for sampling low yield wells
which includes the collection of three field parameters (pH, specific conductance
["conductivity"] and temperature) immediately prior to and immediately following
sample collection. Stabilization of pH, conductivity and temperature were within the
QAP, Revision 7.1 (as corrected in Revision 7.2) required 10% RPD. It is important to
note that redox potential and turbidity were measured as well during purging and
sampling. These parameters were not within 10% RPD; however, these parameters are
not required to be measured or to be within 10% RPD per the approved QAP, Revision
7.2. Data from measurement of these parameters has been provided for information
purposes only.
There are three purging strategies specified in Revision 7.1 (as corrected in Revision 7.2)
of the QAP that are used to remove stagnant water from the casing during groundwater
sampling at the Mill. The three strategies are as follows:
1. Purging three well casing volumes with a single measurement of field parameters
2. Purging two casing volumes with stable field parameters (within 10% RPD)
9
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
3. Purging a well to dryness and stability of a limited list of field parameters after
recovery
All June accelerated samples used strategy number 2 described above and all June
accelerated samples conformed to the QAP requirements for purging prior to sampling.
The review of the field sheets for compliance with QAP, Revision 7.1 (as corrected in
Revision 7.2) requirements resulted in the observations noted below. The QAP
requirements in Attachment 2-3 specifically state that field parameters must be stabilized
to within 10% over at least 2 consecutive measurements. The QAP Attachment 2-3 states
that turbidity should be less than 5 NTU prior to sampling unless the well is characterized
by water that has a higher turbidity. The QAP Attachment 2-3 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 June accelerated
sampling wells except MW-31. As previously stated, the QAP, Revision 7.1 (as
corrected in Revision 7.2) 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.
During review of all of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water for the quarterly, semi-annual and accelerated
sampling programs to the nearest 0.01 foot.
EFR's letter to DRC of March 26, 2010 discusses further why turbidity does not appear
to be an appropriate parameter for assessing well stabilization. In response to DRC's
subsequent correspondence dated June 1, 2010 and June 24, 2010, EFR has completed a
monitoring well redevelopment program. The redevelopment report was submitted to
DRC on September 30, 2011 (under Denison letterhead). Redevelopment results will be
discussed with DRC in an effort to come to a consensus regarding turbidity
considerations for the groundwater wells at the Mill site.
3.4.2 Holding Time Evaluation
QAP Table 1 (both Revision 6 and Revision 7.117.2) 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 A W AL) and temperature blank data sheets (for EL) were
reviewed to confirm compliance with (all revisions of) the QAP requirement in Table 1
that samples be received at 6°C or lower. Sample receipt temperature checks are
10
N:\Required Reports\Oroundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 OW.doc
provided under Tab G. All quarterly, semi-annual and accelerated samples were
received within the required temperature limit.
As noted in Tab G, four groups of samples for tin analyses only were shipped without
using ice. Per Table 1 in all revisions of the approved QAPs that were in effect during
this sampling period, (Revisions 6, 7.1 and 7.2), samples submitted for tin analyses do
not have a sample temperature requirement.
3.4.4 Analytical Method Checklist
All analytical methods reported by both laboratories were checked against the required
methods specified in the appropriate revision of Table 1 of the QAP. Samples collected
prior to May 30, 2012 were checked against Table 1 of Revision 6 of the QAP, dated
March 22, 2010. Samples collected after May 30, 2012, were checked against Table 1 of
Revision 7.2 of the QAP, dated June 6, 2012. Analytical method check results are
provided in Tab G. The review indicated that all quarterly, semi-annual and accelerated
samples were analyzed in accordance with the appropriate revision of Table 1 of the
QAP.
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. The reporting limits are the same in all
revisions of the QAP that were in effect during this quarter. Reporting limit evaluations
are provided in Tab G. All analytes were measured and reported to the required reporting
limits except that several sets of quarterly, semi-annual and accelerated sample results
had the reporting limit raised for at least one analyte due to matrix interference and/or
sample dilution as noted in Section 3.4.9. In all cases the reported value for the analyte
was higher than the increased detection limit.
3.4.6 Trip Blank Evaluation
All trip blank results were reviewed to identify any VOC sample contamination which is
the result of sample handling and shipment. Trip blank evaluations are provided in Tab
G. All trip blank results associated with both the quarterly, semi-annual and accelerated
samples were less than detection level for all VOCs.
3.4.7 QAlQC Evaluation for Routine Sample Duplicates
Section 9.1.4 a) of all revisions of the QAP state 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 are less than 5 times the required detection limit. This standard is based
on the EP A 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
11
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
concentrations are greater than 5 times the required detection limits; however, data will
be considered noncompliant only when the results are greater than 5 times the required
detection limit and the RPD is greater than 20%. The additional duplicate information is
provided for information purposes.
All duplicate results were within a 20% RPD in the quarterly and semi-annual samples
except fluoride in duplicate pair MW -261MW -65. Both of the sample results reported for
MW -261MW -65 were not five times greater than the reporting limit of 0.1 and as such the
deviation from the 20% RPD requirement is acceptable. 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 Radiologies Counting Error and Duplicate Evaluation
Section 9.14 of all revisions of the QAP require 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 QAPs also requires a comparability check between the sample and
field duplicate sample results utilizing the formula provided in the text.
Results of quarterly, semi-annual, and accelerated radiologic sample QC are provided
under Tab G. All quarterly, semi-annual, and accelerated radiologic sample results met
the counting error requirements specified in the QAPs.
3.4.9 Other Laboratory QAlQC.
Section 9.2 of all revisions of the QAP require that the laboratory's QAlQC Manager
check the following items in developing data reports: (1) sample preparation information
is correct and complete, (2) analysis information is correct and complete, (3) appropriate
analytical laboratory procedures are followed, (4) analytical results are correct and
complete, (5) QC samples are within established control limits, (6) blanks are within QC
limits, (7) special sample preparation and analytical requirements have been met, and (8)
documentation is complete. In addition to other laboratory checks described above,
EFR'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.
12
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
Multiple sets of quarterly, semi-annual and accelerated sample results had the reporting
limit raised for at least one analyte due to matrix interference and/or sample dilution. In
all cases the reported value for the analyte was higher than the increased detection limit.
Data are qualified by the laboratory with a "D" flag when the reporting limit is raised due
to dilution or matrix interferences.
The check samples included at least the following: a method blank, a laboratory control
spike ("LCS"), a matrix spike ("MS") and a matrix spike duplicate ("MSD"), or the
equivalent, where applicable. It should be noted that:
• Laboratory fortified blanks are equivalent to LCSs.
• Laboratory reagent blanks are equivalent to method blanks.
• Post digestion spikes are equivalent to MSs.
• Post digestion spike duplicates are equivalent to MSDs.
• For method E900.1, used to determine gross alpha, a sample duplicate was
used instead of a MSD.
All qualifiers, and the corresponding explanations reported in the QAlQC Summary
Reports for any of the check samples for any of the analytical methods were reviewed by
the QA Manager.
All revisions of the QAP, Section 8.1.2 require that a MS/MSD pair be analyzed with
each analytical batch. The QAPs do not specify acceptance limits for the MS/MSD pair,
and the QAPs do not specify that the MS/MSD pair be prepared on EFR 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
requirements in the QAPs to analyze a MS/MSD pair with each analytical batch was met.
While the QAPs do not require it, the recoveries were reviewed for compliance with the
laboratory established acceptance limits. The QAP does not require this level of review
and the results of this review are provided for information only.
The information from the Laboratory QAlQC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all quarterly and semi-annual samples
were within acceptable laboratory limits for all regulated compounds except as indicated
in Tab G. The EL and AWAL data recoveries and RPDs which are outside the laboratory
established acceptance limits do not affect the quality or usability of the data because the
recoveries and RPDs above or below the acceptance limits are indicative of matrix
interference. Matrix interferences are applicable to the individual sample results only.
Furthermore, several of the MS/MSD samples in Work Order Numbers C12050196,
C12050272, C12050443, and C12060029, which were spiked for the MS/MSD analyses,
were not collected at the Mill, and as such the matrix interference is not applicable to the
Mill samples reported herein. The requirement in the QAPs to analyze a MS/MSD pair
with each analytical batch was met and as such the data are compliant with the QAPs.
13
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
The information from the Laboratory QAlQC Summary Reports indicates that the
MSIMSDs 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
MSIMSD samples all Work Order Numbers associated with the accelerated samples
which were spiked for the MSIMSD analyses were not collected at the Mill, and as such
the matrix interference is not applicable to the Mill samples reported herein. The
requirement in the QAPs to analyze a MSIMSD pair with each analytical batch was met
and as such the data are compliant with the QAPs.
The QAPs specify that surrogate compounds shall be employed for all organic analyses
but the QAPs do not specify acceptance limits for surrogate recoveries. The information
from the Laboratory QAlQC Summary Reports indicates that the surrogate recoveries for
all quarterly, semi-annual and accelerated samples were within acceptable laboratory
limits for all surrogate compounds except as indicated in Tab G. The surrogate
compounds outside of acceptance limits, are most likely the result of laboratory spiking
compound degradation. This is apparent because the same surrogate compound was
outside of compliance limits in all samples analyzed within a specific period of time.
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 requirements in the QAPs for surrogate recoveries. I Since surrogate
compounds were added to all of the organic analyses as required by the QAPs, the data
are compliant with the requirements in the QAPs.
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 as noted in Tab G. As indicated on Tab
G, the LCS recoveries which were outside of acceptance limits were above the upper
acceptance limit and as such indicate a high bias to the sample results associated with that
LCS. It is important to note that there is no requirement in the QAPs for LCS recovery
assessment.
All revisions of the QAP, Section 8.1.2 requires that each analytical batch shall be
accompanied by a method blank. All analytical batches routinely contain a blank, which
is a blank sample made and carried through all analytical steps. For the Mill samples, a
method blank was prepared for all analytical methods. Per the approved QAPs,
contamination detected in analysis of method blanks will be used to evaluate any
analytical laboratory contamination of environmental samples. QAP Revision 7.2 states
that non-conformance conditions will exist when contaminant levels in the samples(s) are
not order of magnitude greater than the blank result. One analyte was reported in the
method blanks from EL for the quarterly samples and one analyte was reported in the
method blanks from EL for the accelerated samples. Method blank results are included in
Tab E. In all cases where the associated sample reported a positive detection, the method
sample results were greater than an order of magnitude relative to the method blank
14
N:\Required Reports\Groundwater Quarterly Monitoring Report\2012 Q2\2nd Qtr 2012 GW.doc
results reported, that is the detections meet the QAP criteria. The method blank
detections reported by EL do not affect the quality or usability of the data due to the high
level of the constituents in the samples relative to the associated method blank
concentrations. Additionally, blank detections are indicative of a false positive or high
bias to the sample results as the laboratory contribution to the results would likely cause
higher sample results. The requirement in the QAPs to analyze a method blank with each
batch and evaluate the results has been completed as required.
4.0 CORRECTIVE ACTION REPORT
There are no corrective actions resulting from second quarter 2012 groundwater sampling
event.
5.0 TIME CONCENTRATION PLOTS
Time concentration plots for each monitoring well for the following constituents:
chloride, fluoride, sulfate, and uranium, are included under Tab I. All data points
collected to date are reflected on the plots.
Time concentration plots included with previous quarterly groundwater reports did not
include data which were determined to be outliers using the statistical methods used for
the background determinations at the Mill. Based on conversations with DRC, all data
have been included in the current quarterly time concentration plots. All future time
concentration plots will include all data points.
6.0 ELECTRONIC DATA FILES AND FORMAT
EFR 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 analytical laboratories. A copy of the transmittal e-mail is
included under Tab J.

Notes:
1 GWCL Values are taken from July 14,2011 version of the GWDP.
* THF has not reported an exceedance since Ql 2010 and has had 24 consecutive monitoring results below the GWCL. Based on the April 25, 2012 DRC letter, accelerated monitoring of
THF in MW-ll was stopped as of the June 2012 monthly event.
o Values listed in parentheses are resample results from the same sampling period. Sampled were recollected due field or laboratory problems as noted in the specific report for that
sample period.

RE: Semi Annual Ground Water 2012
Dear JoAnn Tischler: Lab Set ID: 1205087
American West Analytical Laboratories received 9 sample(s) on 5/4/2012 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
QA Officer This is a revision to a report originally issued 5114/2012. Pages 1,2, and 4-12 have been revised.
Thank You, C Digitally signed by Jose G.

RE: Semi Annual Ground Water 2012
Dear JoAnn Tischler: Lab Set ill: 1205130
American West Analytical Laboratories received 5 sample(s) on 5/8/2012 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
QA Officer This is a revision to a report originally issued 5/14/2012. Pages 1, 2, and 5 have been
revised.
Thank You, Patrick Digitally signed by Patrick

RE: Semi Annual Ground Water 2012
Dear JoAnn Tischler: Lab Set ill: 1205202
American West Analytical Laborator~es received 11 sample(s) on 5/11/2012 for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,
Approved by:

RE: Semiannual Ground Water 2012
Dear JoAnn Tischler: Lab Set ill: 1205319
American West Analytical Laboratories received 6 sample(s) on 5118/2012 for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,
Approved by:

RE: Semiannual Ground Water 2012
Dear Garrin Palmer: Lab Set ID: 1205499
American West Analytical Laboratories received 5 sample(s) on 5/30/2012 for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You, ~, Digitally signed by Jose G.

RE: Semiannual Ground Water 2012
Dear Garrin Palmer: Lab Set ill: 1205500
American West Analytical Laboratories received 10 sample(s) on 5/30/2012 for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.

RE: Semiannual Ground Water 2012
Dear JoAnn Tischler: Lab Set ill: 1206010
American West Analytical Laboratories received 2 sample(s) on 6/1/2012 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,
Approved by:

RE: Semi Annual Ground Water 2012
Dear JoAnn Tischler: Lab Set ID: 1206136
American West Analytical Laboratories received 2 sample(s) on 6/8/2012 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.

questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.

REVISED/SUPPLEMENTAL REPORT
Revised Date: 06/27/12
Report Date: 05/30/12
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
June 27,2012 for the correction of the RL for Cobalt on sample MW-25 and for Cadmium on sample MW-35.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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: C12050272
REVISED/SUPPLEMENTAL REPORT
Revised Date: 07/31/12
Report Date: 06/06/12
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by the client to change
the sample date on C12050272-002 to 05/03/12 and the sample 10 to MW-22_05032012. It was also requested that the
VOC's not be reported on samples MW-26 and MW-65. The data presented here reflects these changes.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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: C12050443 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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: C12050723
REVISED/SUPPLEMENTAL REPORT (R3)
Revised Date: 07/31/12
Report Date: 06/15/12
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
July 18, 2012 to report the original Mercury result for sample -002. The data presented here reflects this change.
REVISED/SUPPLEMENTAL REPORT (R2)
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
July 9, 2012 for the reanalysis of dissolved Thallium on sample -001. The data presented here is from that recheck analysis.
REVISED/SUPPLEMENTAL REPORT (R1)
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
July 2, 2012 for the reanalysis of trace metals on sample -002. The data presented here is from that recheck analysis.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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 Groundwater 2012 Report Date: 06/25/12
Sample Delivery Group: C12060029 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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.

CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum fecommended 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.

CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are 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.

CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
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

RE: April Monthly Ground Water 2012
Dear JoAnn Tischler: Lab Set ill: 1204240
American West Analytical Laboratories received 2 sample(s) on 4113/2012 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
Institute in Utah and Texas; and is state accredited in Colorado, Idaho, and Missouri.
Accreditation documents are available upon request. If you have any questions or
concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be reported
by the method referenced and the sample matrix. The reporting limit must not be confused
with any regulatory limit. Analytical results are reported to three significant figures for
quality control and calculation purposes.
Thank You,
Approved by:

Sample Delivery Group: C 12060935 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay if! 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 sevefl 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: C12070037 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
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.

Standard Reporting Procedures
Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as pH, Dissolved Oxygen and Residual
Chlorine, are qualified as being analyzed outside of recommended holding time.
Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected, data units are typically noted as -dry.
For agricultural and mining soil parameters/characteristics, all samples are dried and ground prior to sample analysis.

The QAP states that turbidity should be less than 5 Nephelometric 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 NTD prior to sampling. As such, the noted
observations regarding turbidity measurements less than 5 NTU are included for information purposes only.
MW-26IS a contmuously pumped well.
ell was purged dry. Wells MW-03A, MW-12, MW-23, MW-24, and MW-37 were sampled prior to the approval of the revised QAPs, Revisions 7.1 and 7.2 and as such the field parameter measurement procedures were in accordance with the approved QAP, Revision 6, which did not require parameters prior to and
subs uenet to sample collection.
N/A = The amount of water in the well was insufficient to purge. The pump was not able to operate due to the minimal amount of water. The well was sampled with a bailer.
RPD >10%. Per the revised QAPs Revisions 7.1 and 7.2, Attachment 2-3, when a well is purged to dryness, only pH, temperature and specific conductance parameters are required to be within 10% RPD. Redox potential and turbidity paramters are measured for information purposes only and as such are not required to
meet the 10% RPD criteria used for pH, specific conductance and temperature ..
