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 fourth
quarter of 2011 (the "quarter") for Denison Mines (USA) Corp's. ("DUSA's") White
Mesa Uranium Mill (the "Mill"). As required under Parts I.E. 1, I.E.2 and I.E.S of the
GWDP this Report includes all recorded field measurements and laboratory analyses for
well monitoring conducted during the quarter.
2.0 GROUNDWATER MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, chloroform contaminant investigation wells and nitrate contaminant investigation
wells is attached under Tab A. Groundwater samples and measurements were taken
during this reporting period (October through December), as discussed in the relnainder
of this section.
Also included in this report are revised tin data for the groundwater samples collected
during the third quarter 2011.. The original third quarter 2011 samples were reanalyzed
for tin during the fourth quarter 2011 due to laboratory issues as discussed in Section
2.1.4. The third quarter 2011 tin results are being submitted in this fourth quarter report
consistent with Part I.E.2.(a) of the GWDP as discussed in Section 2.1.4 below.
It is important to note that a Division of Radiation Control ("DRC") Representative was
present for the October 3, 2011 sampling. The DRC Representative collected split
samples on October 3,2011 from MW-31 and MW-3S.
2.Ll 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, eighteen wells and two duplicates were resampled for ammonia due to laboratory
1
N:\Required Reports\Groundwater Quarterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
issues which resulted in the original sample results being reported with raised Reporting
Limits ("RLs"). The resampled results were reported with correct RLs. In addition one
well was resampled for tetrahydrofuran ("THF") due to a laboratory instrument failure.
The following is a list of wells which were resampled:
• MW-01, MW-02, MW-03, MW-03A, MW-12, MW-14, MW-15, MW-17, MW-
18, MW-19, MW-23, MW-27, MW-28, MW-30, MW-31, MW-35, MW-36,
MW-37, MW-65 (duplicate of MW-02), and MW-70 (duplicate ofMW-18) were
resampled for ammonia due to a laboratory issue which resulted in the original
results being reported with elevated RLs. Results of the reanalysis provided in
this report are reported with correct RLs.
• MW -11 was resampled for THF due to a laboratory instrument failure which
resulted in the loss of the sample.
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 a~ded to the GWDP on February 15,2011, which required the Mill to
begin quarterly sampling of wells MW -35, MW -36 and MW -37 to develop eight quarters
of background data. MW-35, which was installed in the third quarter 2010, has been
sampled quarterly since fourth quarter 2010. MW-36 and MW-37, which were installed
during the second quarter 2011, were sampled for the first time during the 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.l.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.
The GWDP, Part I.E. 1. (a) states that "all groundwater monitoring and analysis performed
under this Permit shall be conducted in accordance with a Quality Assurance Plan
("QAP") currently approved by the Executive Secretary. Any non-conformance with
2
N:\Required Reports\Groundwater Quarterly Monitoring Report\20 11 Q4\4th Qtr 2011 GW.doc
QAP requirements in a given quarterly groundwater monitoring period will be corrected
and reported to the Executive Secretary on or before submittal of the next quarterly
groundwater monitoring report pursuant to Part I.F.l." Denison's approved QAP and the
GWDP, require that all analyses will be completed using Utah-certified laboratories.
Tin data from Energy Laboratories ("EL") for the third quarter 2011 samples was
originally reported in the third quarter report submitted to DRC in the Third Quarter
2011 Groundwater Monitoring Report, dated November 30, 201l. During a review of
laboratory certifications conducted in December 2011, after the submission of the third
quarter 2011 report, Denison noted that EL's Utah Department of Health, Bureau of
Laboratory Inlprovement, Environmental Laboratory Certification ("Utah Certification")
for tin expired on June 30, 201l. It was noted that EL, had maintained their Utah
certification through the end of the second quarter of 2011 (June 30, 2011), so all
previous data analyzed by EL were unaffected.
Pursuant to Part I.E.l.(a), Denison notified DRC by phone on February 6, 2012 and
Denison arranged for the reanalysis of the third quarter 2011 samples by American 'West
analytical laboratories ("A W AL") which had a current Utah Certification for tin. As
required by Part I.E.l.(a), the non-conformance has been corrected prior to the next
quarterly groundwater monitoring report, DRC has been notified, and the reanalyzed tin
data for the third quarter 2011 samples are included in this report.
Prior to the reanalysis, Denison reviewed the holding times, storage procedures and
remaining sample volumes to assure the reanalysis would yield data of acceptable
quality. It was noted that:
• The third quarter 2011 samples were collected in August 2011 and were still
within the 6 month holding time specified by the analytical method in early
December when the certification discrepancy was noted.
• Storage procedures were noted as acceptable and sample integrity had been
preserved. /
• Sufficient volume of all samples remained to allow analysis.
As mentioned above, A WAL completed the tin reanalysis on the third quarter 2011
samples. AWAL's tin certification was and remains current and the data meet the
requirement of the QAP and the GWDP that all analyses be completed by Utah-certified
laboratories. The corrective actions specified in Part I.E.l.(a) have also been met with
the resubmission of the data with this report.
2.1.5 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant
to Part I.E.2 of the GWDP dated February 15,2011:
• The quarterly groundwater compliance monitoring wells (including, MW-34).
3
N:\Required Reports\Groundwater Qual1erly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-1, P-2, P-3, P-4 and P-S.
• Nitrate monitoring wells.
• 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 October) 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
November and December 2011 accelerated monitoring and sampling efforts.
It is important to note that the field data sheet appearance has changed a_s a result of the
implementation of an electronic data capture system. The field data sheets contain the
same information as the field data sheet attached to the approved QAP in approxinlately
the same location. There are absolutely no changes in the information collected on the
electronic capture field form. All data are still collected using a pen and the hard copy
form. The difference in the field form is the formatting of the cells which now have
boxes around the input areas rather than plain lines. The new data sheets allow the
electronic capture of data while still maintaining the real-time recording of information
manually in ink as required by DRC. The changes were made to accommodate the data
recording and validation system. It is also important to note that the approved QAP,
Section 7.1 requires the use of a field data sheet, and notes that "An example of a Field
Data Worksheet that incorporates ... .is included as Attachment I." The QAP does not
state that the form included in Attachment 1 will be used, but is an example of a form that
incorporates the required information. Based on the wording of the currently approved
QAP, any form that incorporates the required information is allowable. The wording in
the approved QAP does not preclude the use of a re-formatted Field Data Worksheet
provided the required information is collected.

2.3 Laboratory Results -Quarterly Sampling
2.3.1 Copy of Laboratory Results
All analytical results are provided by one of the Mill's two contract analytical
laboratories 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, and the third quarter 2011 tin data as identified
in Table 1.
The laboratory report dates for samples collected for the November and December
accelerated sampling (i.e. quarterly accelerated to monthly) are provided in Table 1.
Results from analysis of samples collected for the November and December 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 sam.pling conducted since that time.
5
N:\Required Reports\Groundwater Quarterly Monitoring Report\20 II Q4\4th Qtr 2011 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 DUSA's letter to DRC on February 15, 2012. Table 3 summarizes the results of the
accelerated sampling program from first quarter 2010 through fourth quarter 2011.
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." DUSA submitted an
exceedance notice on February 15, 2012 for the fourth quarter 2011 results. The
summary in the Exceedance Notice includes, for each exceedance, a brief discussion of
whether such a plan and schedule is required at this time in light of other actions
currently being undertaken by Denison, as determined by DRC Staff and stated in
teleconferences with Denison on April 27 and May 2, 2011.

N:\Required Reports\Groundwater Quruterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
2.5 Depth to Groundwater and Water Table Contour Map
As stated above, a listing of groundwater level readings for the quarter (shown as depth to
groundwater in feet) is included under Tab D. The data from Tab D has been interpreted
(kriged) and plotted in a water table contour map, provided under Tab H.
The water table contour map provides the location and identity of all of the wells and
piezometers for which depth to groundwater is recorded. The groundwater elevation at
each well and piezometer, measured in feet above mean sea level, and isocontour lines to
delineate groundwater flow directions observed during the quarter's sampling event are
displayed on the map.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The Mill QA Manager performed a QAlQC review to confirm compliance of the
monitoring program with requirements of the QAP. As required in the QAP, data QA
includes preparation and analysis of QC samples in the field, review of field procedures,
an analyte completeness review, and quality control review of laboratory data methods
and data. Identification of field QC samples collected and analyzed is provided in
Section 3.1. Discussion of adherence to Mill sampling Standard Operating Procedures
("SOPs") is provided in Section 3.2. Analytical completeness review results are provided
in Section 3.3. The steps and tests applied to check laboratory data QAlQC are discussed
in Sections 3.4.4 through 3.4.10 below.
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
QA/QC information are provided under Tab G and discussed in Section 3.4, below.
3.1 Field QC Samples
The following field QC samples were generated by Mill personnel and submitted to the
analytical laboratory in order to assess the quality of data resulting from the field
sampling program:
Two duplicate samples were collected during quarterly sampling as indicated in Table 1.
The QC samples were sent blind to the analytical laboratory and analyzed for the same
parameters as permit-required samples.
One duplicate sample was collected during each month of accelerated sampling as
indicated in Table 1. The QC samples were sent blind to the analytical laboratory and
anal yzed for the same accelerated parameters as the parent sample.
7
N:\Required Reports\Groundwater Quarterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
Three trip blanks were provided by EL and returned and analyzed with the quarterly
monitoring samples.
One trip blank per month was provided by EL and returned and analyzed with the
accelerated monthly monitoring samples.
Three trip blanks were provided by A W AL and returned and analyzed with the quarterly
monitoring samples.
One trip blank per month was provided by A W AL and returned and analyzed with the
accelerated monitoring samples.
Rinsate samples were not collected during the quarter because all equipment used during
sample collection was dedicated and did not require decontamination. All wells except
MW-37 have dedicated pumps for purging and sampling and as such no rinsate blanks
samples are required. MW-37 was sampled with a disposable bailer and no rinsate blank
was required. A deionized field blank (DIFB) was not required because equipment
decontamination was not required and deionized water was not used during this sampling
event.
3.2 Adherence to Mill Sampling SOPs
On a review of adherence by Mill personnel to the existing sampling SOPs, the QA
Manager observed that QAlQC requirements established in the QAP were being adhered
to and that the SOP's were implemented, except as described below.
3.3 Analyte Completeness Review
All analyses required by the GWDP for the quarterly and semi-annual wells were
performed. The accelerated sampling for the semi -annual wells (semi -annual to
quarterly) was completed as required by the GWDP and as shown in Tables 2 and 3. The
accelerated quarterly sampling (quarterly to monthly) required for this quarter, as shown
in Tables 2 and 3, was performed as required.
3.4 Data Validation
The QAP and GWDP identify the data validation steps and data quality control checks
required for the groundwater monitoring program. Consistent with these requirements,
the QA Manager performed the following evaluations: a field data QAlQC evaluation, a
receipt temperature check, a holding time check, an analytical method check, a reporting
limit check, a trip blank check, a QAlQC evaluation of routine sample duplicates, a
QAlQC evaluation of accelerated sample duplicates, a gross alpha counting error
evaluation and a review of each laboratory's reported QAlQC information. Each
evaluation is discussed in the following sections. Data check tables indicating the results
of each test are provided under Tab G.

N:\Required Reports\Groundwater Quarterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
3.4.1 Field Data QAlQC Evaluation
The QA Manager performs a review of all field recorded parameters to assess their
adherence with QAP requirements. The assessment involved review of two sources of
information: the Field Data Sheets and the Quarterly Depth to Water summary sheet.
Review of the Field Data Sheets addresses well purging volumes and stability of five
parameters: conductance, pH, temperature, redox potential, and turbidity. Review of the
Depth to Water data confirms that all depth measurements were conducted within a five-
day period. The results of this quarter's review are provided in Tab G.
Based upon this review, all quarterly and semi-annually sampled locations conformed to
the QAP requirement to evacuate two well casing volumes before sampling except for
MW-03A, MW-12, MW-20, MW-23, MW-24 and MW-37. These wells were evacuated
to dryness before two casing volumes could be pumped. MW-20 and MW-37 have
insufficient water to purge using a pump. Due to the small volume of water present,
samples were collected using disposable bailers.
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
Section 6.2.7(d)(v) of the QAP.
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, semi-annual and accelerated
sampling programs to the nearest 0.01 foot.
The review of the field sheets for compliance with QAP requirements resulted in the
observations noted below. The QAP requirements in Section 6.2.7 specifically state that
field parameters have to be stabilized to within 10% over at least 2 consecutive
measurements. The QAP states that turbidity should be less than 5 Nephlometric
Turbidity Units ("NTU") prior to sampling unless the well is characterized by water that
has a higher turbidity. The QAP does not require that turbidity measurements be less
than 5 NTU prior to sampling. As such the noted observations regarding turbidity
measurements greater than 5, NTU below are included for information purposes only.
• Turbidity measurements were less than 5 NTU for all of the quarterly and semi-
annual wells except MW-01, MW-01 resample, MW-03A resample, MW-12,
MW-12 resample, MW-19 resample, MW-20, MW-22, MW-23, MW-23
resample, MW-24, MW-25, MW-29, and MW-37. Per the QAP Section 6.2.7 d)
9
N:\Required Repons\Groundwater QuaIterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
(v) Turbidity measurements prior to sampling were within a 10% Relative Percent
Difference ("RPD") for all quarterly and semi-annual wells.
• Turbidity measurements were less than 5 NTU for all of the accelerated sampling
wells except MW -11 in the December monthly sampling event. As previously
stated, the QAP does not require that turbidity be less than 5 NTU. Turbidity
measurements prior to sampling were within a 10% RPD for all accelerated
sampling wells
DUSA's letter to DRC of March 26, 2010 discusses further why turbidity does not appear
to be an appropriate parameter for assessing well stabilization. In response to DRC's
subsequent correspondence dated June 1,2010 and June 24,2010, DUSA has completed
a monitoring well redevelopment program. The redevelopment report was submitted to
DRC on September 30, 2011. Redevelopment results will be discussed with DRC in an
effort to come to a consensus regarding turbidity considerations for the groundwater
wells at the Mill site.
All other field parameters (conductance, pH, redox potential, and temperature) for all
wells were within the required RPD for the quarterly, semi-annual and accelerated
sampling.
3.4.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample
holding time checks are provided under Tab G. All samples were received and analyzed
within the required holding time.
3.4.3 Receipt Temperature Evaluation
Chain of Custody sheets (for AWAL) and temperature blank data sheets (for EL) were
reviewed to confirm compliance with the QAP requirement in QAP Table 1 that samples
be received at 6°C or lower. Sample receipt temperature checks are provided under Tab
G. All quarterly, semi-annual and accelerated samples were received within the required
temperature limit.
3.4.4 Analytical Method Checklist
All analytical methods reported by both laboratories were checked against the required
methods specified in Table 1 of the QAP. Analytical method check results are provided
in Tab G. The review indicated that all quarterly, semi-annual and accelerated samples
were analyzed in accordance with Table 1 of the QAP.
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
10
N:\Required Reports\Groundwater Quarterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
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 QA/QC Evaluation for Routine Sample Duplicates
Section 9.1.4 a) of the QAP states that RPDs will be calculated for the comparison of
duplicate and original field samples. The QAP acceptance limits for RPDs between the
duplicate and original field sample is less than or equal to 20% unless the measured
results (described as activities in the QAP) are less than 5 times the required detection
limit. This standard is based on the EPA Contract Laboratory Program National
Functional Guidelines for Inorganic Data Review, February 1994, 9240.1-05-01 as cited
in the QAP. The RPDs are calculated for all duplicate pairs for all analytes regardless of
whether or not the reported concentrations are greater than 5 times the required detection
limits; however, data will be considered noncompliant only when the results are greater
than 5 times the required detection limit and the RPD is greater than 20%. The additional
duplicate information is provided for information purposes.
All duplicate results were within a 20% RPD in the quarterly and semi-annual samples
except iron in duplicate pair MW -181MW -70. The sample results reported for MW-
181MW-70 were not five times greater than the reporting limit of 30 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 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 GW~L, shall have a counting variance that is equal to or less
than 20% of the reported activity concentration. An error term may be greater than 20%
of the reported activity concentration when the sum of the activity concentration and
error term is less than or equal to the GWCL.
Section 9.4 of the QAP also requires a comparability check between the sample and field
duplicate sample results utilizing the fonnula provided in the text.
11
N:\Required Reports\Groundwater Quarterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
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 QAP.
3.4.9 Other Laboratory QAlQC.
Section 9.2 of the QAP requires that the laboratory's QAlQC Manager check the
following items in developing data reports: (1) sample preparation information is correct
and complete, (2) analysis information is correct and complete, (3) appropriate analytical
laboratory procedures are followed, (4) analytical results are correct and complete, (5)
QC samples are within established control limits, (6) blanks are within QC limits, (7)
special sample preparation and analytical requirements have been met, and (8)
documentation is complete. In addition to other laboratory checks described above,
DUSA's QA Manager rechecks QC samples and blanks (items (5) and (6)) to confirm
that the percent recovery for spikes and the relative percent difference for spike
duplicates are within the method-specific required limits, or that the case narrative
sufficiently explains any deviation from these limits. Results of this quantitative check
are provided under Tab G. All lab QAlQC results from both EL and A W AL samples for
compounds regulated under the GWDP met these requirements. There were QC results
which did not meet laboratory established acceptance limits, as identified in Tab G and
described below.
_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 QA/QC Summary
Reports for any of the check samples for any of the analytical methods were reviewed by
the QA Manager.
The QAP Section 8.1.2 requires that a MSIMSD (referred to as Duplicate Spike [Matrix
spike] in the QAP) pair be analyzed with each analytical batch. The QAP does not
12
N:\Required Reports\Groundwater Qualterly Monitoring Report\20 11 Q4\4th Qtr 2011 GW.doc
specify acceptance limits for the MS/MSD pair, and the QAP does not specify that the
MS/MSD pair be prepared on DUSA samples only. Acceptance limits for MSIMSDs are
set by the laboratories. The review of the information provided by the laboratories in the
data packages verified that the QAP requirement to analyze a MSIMSD pair with each
analytical batch was met. While the QAP does not require it, the recoveries were
reviewed for compliance with the laboratory established acceptance limits. The QAP
does not require this level of review and the results of this review are provided for
information only.
The information from the Laboratory QAlQC Summary Reports indicates that the
MSIMSDs 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, the MSIMSD samples in Work Order Numbers C11100300 and C11100842
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 QAP
requirement to analyze a MSIMSD pair with each analytical batch was met and as such
the data are compliant with the QAP.
The information from the Laboratory QAlQC Summary Reports indicates that the
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 in Work Order Numbers Cll110484 and Cll120540 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 QAP requirement
to analyze a MSIMSD pair with each analytical batch was met and as such the data are
compliant with the QAP.
The QAP specifies that surrogate compounds shall be employed for all organic analyses
but the QAP does not specify acceptance limits for surrogate recoveries. The information
from the Laboratory QAlQC Summary Reports indicates that the surrogate recoveries for
all quarterly, semi-annual and accelerated samples were within acceptable laboratory
limits for all surrogate compounds except as indicated in Tab G. In all instances the
surrogate recoveries outside of acceptance limits were above the upper limit or had a high
recovery, indicating a high bias to the individual sample results. A high bias means that
reported results for this analyte will tend to be higher than the actual concentration.
There is no effect on the quality or usability of the data because there are multiple
surrogates added to each sample and all other surrogates were within limits. Furthermore,
there are no QAP requirements for surrogate recoveries. Since surrogate compounds
13
N:\Required Reports\Groundwater Quarterly Monitoring Report\2011 Q4\4th Qtr 2011 GW.doc
were added to all of the organic analyses as required by the QAP, the data are compliant
with the QAP requirements.
The infornlation from the Laboratory QAlQC Summary Reports indicates that the LCS
recoveries for both the quarterly and accelerated samples were within acceptable
laboratory limits for all LCS compounds except for chloromethane in one routine sample
batch and one accelerated sample batch and naphthalene in one analytical batch for the
accelerated sampling. As indicated on Tab G, the LCS recovery for naphthalene was
below the lower acceptance limit and as such indicate a low bias to the sample results
associated with that LCS for naphthalene only. As indicated on Tab G, the LCS recovery
for chloromethane was above the upper acceptance limit and as such indicate a high bias
to the sample results associated with that LCS for chloromethane only. It is important to
note that there is no QAP requirement for LCS recovery assessment.
The QAP Section 8.1.2 requires that each analytical batch shall be accompanied by a
reagent blank. All analytical batches routinely contain a blank, which is a blank sample
made and carried through all analytical steps. For the NIill samples, a method blank is
prepared for all analytical methods. Per the approved QAP, contamination detected in
analysis of method blanks will be used to evaluate any analytical laboratory
contamination of environmental samples. The QAP does not specify the process for
evaluation of method blanks. For consistency, the QAP required evaluation criteria for
rinsate blanks will be used. The QAP criteria for rinsate blanks states that
nonconformance will exist when blanks are within an order of magnitude of the sample
results. One analyte was reported in the method blanks from EL. Method blank results
are included in Tab E. In all cases where the associated sample reported a positive
detection, the method blank results were less than an order of magnitude relative to the
positive sample results reported, that is the detections meet the QAP criteria. The method
blank detection reported by EL does not affect the quality or usability of the data due to
the high level of the constituents in the samples relative to the associated method blank
concentrations. Additionally, blank detections are indicative of a false positive or high
bias to the sample results as the laboratory contribution to the results would likely cause
higher sample results. The QAP requirement to analyze a method blank with each batch
and evaluate the results has been completed as required.
3.4.10 Third Quarter 2011 Tin Data
As previously stated, the third quarter 2011 groundwater samples were reanalyzed for tin
due to the expiration of EL's Utah Certification for tin. The QC checks required by the
QAP and GWDP are not included in the tables in Tab G, but are discussed below. It
should be noted that the original samples collected in August 2011, were sent from EL to
AWAL for the reanalysis of tin in December 2011 and analyses were performed within
holding times. Detailed discussions of the field QC, field data, and sampling protocols
are reported in the Third Quarter 2011 Groundwater Monitoring Report, dated
November 30, 2011; however, no problerns that affect ~he quality or usability of the
sanlples were noted in that report.
14
N:\Required Reports\Groundwater Quarterly Monitoring Report\20l1 Q4\4th Qtr 2011 GW.doc
The tin data reported herein, in combination with the previously reported data, provides
all data required by the GWDP for the quarterly wells.
Holding time, analytical method, and RL reviews indicate that all requirements were met.
Receipt temperatures for the initial shipment to EL and the second shipment from EL to
AWAL for the reanalysis in Decernber were within the acceptable limits.
Trip blanks are not required for metals analysis.
The RPD for the parent/duplicate were not calculated as neither the sample nor the
duplicate had reported detections of tin.
Other laboratory QC such as the MSIMSD pair, the method blanks and the LCS were all
acceptable.
4.0 CORRECTIVE ACTION REPORT
There are no corrective actions resulting from fourth quarter 2011 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
DUSA has provided to the Executive Secretary electronic copies of all laboratory results
from groundwater quality monitoring conducted during the quarter in Comma Separated
Values ("CSV"), from the EL data; and in Electronic Data Deliverable ("EDD") format
from the A W AL data. A copy of the transmittal e-mail is included under Tab J.

Notes:
I GWCL Values are taken from July 14, 2011 version of the GWDP.
* THF has not reported an exceedance since QI 2010 and has had 21 consecutive monitoring results below the GWCL. Although based on previous instances, UDEQ has dropped
accelerated monitoring after 8 periods of results below the GWCL, UDEQ requires continued monitoring of this constituent.
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.
Highlighted text shows accelerated requirements resulting from Q4 20 II sampling event.

Comments: TW4-27 was purged yesterday on 12/20/2011 for well development and the static has not recovered to normal static.
TW4-27 also needs bumper posts, labeled, painted, and locked. Some well times may be the same because we split up to take depths

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, Idaho, and Missouri.
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 sl!f.(pgate 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

Tetrahydrofuran
General Set Comments: Tetrahydrofuran was observed above reporting limits on sample
1110106-003A.
Holding Time and Preservation Requirements: All samples were received in appropriate
containers and properly preserved. The analysis and preparation of all samples were
performed within the method holding times following the methods stated on the analytical
reports.
Analytical QC Requirements: All instrument calibration and calibration check
requirements were met. All internal standard recoveries met method criterion.
Batch QC Requirements: MB, LCS, MS, MSD, RPD, and Surrogates:
Method Blanks (MBs): No target analytes were detected above reporting limits,
indicating that the procedure was free from contamination.
Laboratory Control Sample (LCSs): All LCS recoveries were within control
limits, indicating that the preparation and analysis were in control.
Matrix Spike 1 Matrix Spike Duplicate (MS/MSD): The RPD was high on
tetrahydrofuran for sample 1110106-014A due to suspected sample non-
homogeneity or matrix interference. The MSIMSD percent recoveries were inside
established limits.
Surrogates: All surrogate recoveries were within established limits.
Corrective Action: None required.

RE: Semi Annual Ground Water 2011
Dear Jo Ann Tischler: Lab Set ID: 1110278
American West Analytical Laboratories received 13 sample( s) on 10114/2011 for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado, Idaho, and Missouri.
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 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: Semi Annual Ground Water
Dear Jo Ann Tischler: Lab Set ID: 1110409
American West Analytical Laboratories received 3 sample(s) on 10/21/2011· for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado, Idaho, and Missouri.
Certification document is available upon request. If you have any questions or concerns
regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, andlor
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical 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.

Matrix: Aqueous
Received Date/Time: 10107/11 09:25
Analysis Requested: Dissolved Tin
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

Laboratory ID: C111 00567-001 through -012
Matrix: Aqueous
Received DatelTime: 10/14/11 09:20
Analysis Requested: Dissolved Tin
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

SUB-CONTRACTED ANALYSIS
The service requested for your samples was sub-contracted to American West Analytical Laboratories for analysis.
Enclosed is the resulting data.
Sub-lab Accreditation #: NELAC (Utah) -Contact sub lab for Accreditation #
Sample 10: MW-20, MW-37
Laboratory 10: C111 00842-001 through -002
Matrix: Aqueous
Received DateiTime: 10/21/11 09:35
Analysis Requested: Dissolved Tin
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

Project: 4th Quarter Groundwater 2011 (Resample) Report Date: 12/08/11
Sample Delivery Group: C11120054 CASE NARRATIVE
REVISED/SUPPLEMENTAL REPORT
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
December 9,2011 to report the Method Blank to the sample RL.
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 90t 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.

REVISED/SUPPLEMENTAL REPORT
Revised Date: 12/28/11
Report Date: 12/21/11
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
December 22,2011 to change the collection date on sample MW-37 to 12/9/2011.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

RE: 3rd Quarter Groundwater 2011 (C11080269)
Dear Kerri Schroeder: Lab Set ID: 1112163
American West Analytical Laboratories received 3 sample(s) on 12/9/2011 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is 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 inj ection, extraction, andlor
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 on 12115/2011. The units and the reporting
limits have been updated. Pages 1 and 3-9 have been revised.
Thank You,

RE: 3rd Quarter Groundwater 2011 (C11080529)
Dear Kerri Schroeder: Lab Set ill: 1112162
American West Analytical Laboratories received 2 sample(s) on 12/9/2011 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC mstitute protocols unless
noted otherwise. American West Analytical Laboratories is accredited by The NELAC
mstitute 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, andlor
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 on 12115/2011. The units and the reporting
limits have been updated. Pages 1 and 3-8 have been revised.

RE: November MonthJy Ground Water 2011
Dear Jo Puln Tischler: Lab Set ID: 1111214
AmericaniWest Analytical Laboratories received 2 sample(s) on 11/11/2011 for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado, Idaho, and Missouri.
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 quantitation limit (PQL). This is the minimum concentration that can be reported
by the method referenced and the sample matrix. The reporting limit must not be confused
with any regulatory limit. Analytical results are reported to three significant figures for
quality control and calculation purposes.

Sample Delivery Group: C11110484 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

RE: December Monthly Ground Water 2011
Dear JoAnn Tischler: Lab Set ID: 1112427
American West Analytical Laboratories received 2 sample(s) on 12/28/2011 for the
analyses presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is 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:

Tetrahydrofuran
General Set Comments: Tetrahydrofuran was not observed above reporting limits.
Holding Time and Preservation Requirements: All samples were received in appropriate
containers and properly preserved. The analysis and preparation of all samples were
performed within the method holding times following the methods stated on the analytical
reports.
Analytical QC Requirements: All instrument calibration and calibration check
requirements were met. All internal standard recoveries met method criterion.
Batch QC Requirements: MB, LCS, MS, MSD, RPD, and Surrogates:
Method Blanks (MBs): No target analytes were detected above reporting limits,
indicating that the procedure was free from contamination.
Laboratory Control Sample (LCSs): All LCS recoveries were within control
limits, indicating that the preparation and analysis were in control.
Matrix Spike 1 Matrix Spike Duplicate (MSIMSD): The MS percent recovery
was outside of control limits due to sample matrix interference and the RPD
(Relative Percent Difference) was high due to suspected sample non-homogeneity
or matrix interference on tetrahydrofuran for sample 1112427-001A. The MSD
percent recovery was inside established limits
Surrogates: All surrogate recoveries were within established limits.
Corrective Action: None required.

Sample Delivery Group: C11120540 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.
