1.0 INTRODUCTION
The presence of chloroform was initially identified in groundwater at the White Mesa
Mill (the "Mill") as a result of split sampling performed in May 1999. The discovery
resulted in the issuance of State of Utah Notice of Violation ("NOV") and Groundwater
Corrective Action Order ("CAO") State of Utah Department of Environmental Quality
("UDEQ") Docket No. UGW-20-01, which required that Energy Fuels Resources (USA)
Inc. ("EFRI") submit a Contamination Investigation Plan and Report pursuant to the
provisions ofUAC R317-6-6.15(D).
The frequency of chloroform sampling, which was initially performed on a monthly
basis, was modified on November 8, 2003. Since that time all chloroform contaminant
investigation wells have been sampled on a quarterly basis.
This is the Quarterly Chloroform Monitoring Report for the third quarter of 2012 as
required under the NOV and CAO. This Report also includes the Operations Report for
the Long Term Pump Test at MW-4, TW4-19, MW-26 (previously referred to as TW4-
15), TW4-20, and TW4-4 for the quarter.
1.1 Groundwater Discharge Permit Modifications during the Quarter
During the third quarter of 2012, the approved July 14, 2011 GWDP was revised on
August 24, 2012. The revision incorporated the EFRI name change from Denison Mines
(USA) Corp. No changes were issued to the groundwater monitoring program described
herein.
2.0 CHLOROFORM MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, temporary chloroform contaminant investigation wells and temporary nitrate
investigation wells is attached under Tab A. Chloroform samples and measurements
taken during this reporting period are discussed in the remainder of this section.
2.1.1 TW 4-27
Installation of the new perched groundwater monitoring well, TW4-27, was completed on
November 8, 2011, as required by the May 26, 2011 DRC Request for Additional
Information ("RFI"), and as delineated in the Final EFRI Work Plan and Schedule to
Drill and Install Well TW4-27 (the "Plan"), submitted to DRC on October 3,2011.
Per section 1.2 of the Plan, water level and chloroform concentration data will be
collected from existing wells, as well as TW4-27, to determine if TW4-27 satisfies the
stipulated criteria. TW 4-27 will satisfy the stipulated criteria if the 70 ug/L chloroform
isoconcentration line remains hydraulically up gradient of TW 4-27, and groundwater
contour lines show that TW 4-27 is hydraulically downgradient of TW 4-4 and TW 4-6.
1
N:\ WMM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q3\20 12_ Q3Chloroform _Report _text. doc
In addition to the criteria in section 1.2, section 1.3 of the Plan states that if water level
data from TW4-27 indicates that the water level at TW4-14 is anomalous, TW4-14 will
be abandoned, with the approval of the Director of the Division of Radiation Control. The
water level at TW4-14 will be considered anomalous if the water level at TW4-27 is
comparable to the water level at TW 4-6.
First and second quarter 2012 water level and analytical data collected from TW4-27
indicate that the 70 ug/L chloroform isoconcentration· line remains hydraulically
upgradient of TW4-27, and that TW4-27 is hydraulically downgradient of TW4-4 and
TW 4-6, satisfying the criteria described above. Furthermore, because the water level at
TW4-27 is similar to the water level at TW4-14, but is approximately 14 feet lower than
the water level at TW 4-6, the water level at TW 4-14 is not considered anomalous, and
the section 1.3 abandonment criteria are not met.
2.1.2 Chloroform Monitoring

Table 1 provides an overview of all wells sampled during the quarter, along with the date
samples were collected from each well, and the date(s) which analytical data were
received from the contract laboratory. Table 1 also identifies equipment rinsate samples
collected, as well as sample numbers associated with the deionized field blank ("DIFB")
and any required duplicates.
As indicated in Table 1, chloroform monitoring was performed in all of the required
chloroform monitoring wells.
2.1.3 Parameters Analyzed
Wells sampled during this reporting period were analyzed for the following constituents:
• Chloroform
• Chloromethane
• Carbon tetrachloride
• Methylene chloride
2
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q3\2012_ Q3Chloroform_Report_textdoc
• Chloride
• Nitrate plus Nitrite as Nitrogen
Use of analytical methods is consistent with the requirements of the Chloroform
Investigation Monitoring Quality Assurance Program (the "Chloroform QAP") attached
as Appendix A to the White Mesa Uranium Mill Groundwater Monitoring QAP Revision
7.2, dated June 6, 2012.
2.1.4 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells andlor piezometers, pursuant
to Part I.E.3 of the Groundwater Discharge Permit (the "GWDP"):
• The quarterly groundwater compliance monitoring wells.
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-1, P-2, P-3, P-4 and P-5.
• MW-20 and MW-22.
• ' Nitrate monitoring wells.
• The DR piezometers which were installed during the Southwest Hydrologic
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~
In addition, weekly and monthly depth to groundwater measurements were taken in MW-
4, MW-26, TW4-19, TW4-20, and TW4-4, as part of the long term pumping test for
MW-4.
2.2 Sampling Methodology and Equipment and Decontamination Procedures
EFRI completed, and transmitted to UDEQ on May 25, 2006, a revised QAP for
sampling under the Mill's Groundwater Discharge Permit ("GWDP"). While the water
sampling conducted for chloroform investigation purposes has conformed to the general
principles set out in the QAP, some of the requirements in the QAP were not fully
implemented prior to UDEQ's approval, for reasons set out in correspondence to UDEQ
dated December 8, 2006. Subsequent to the delivery of the December 8, 2006 letter,
EFRI discussed the issues brought forward in the letter with UDEQ and has received
correspondence from UDEQ about those issues. In response to UDEQ's letter and
subsequent discussions with UDEQ, EFRI has incorporated changes in chloroform
Quality Assurance ("QA") procedures in the form of the Chloroform QAP. The
Chloroform QAP describes the needs of the chloroform investigation program where they
differ from the Groundwater QAP. On June 20, 2009 the Chloroform QAP was modified
to require that the quarterly chloroform reports include additional items specific to
EFRI's ongoing pump testing and chloroform capture efforts. The Groundwater QAP as
well as the Chloroform QAP were revised again on June 7, 2012. The revised
3
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q3\2012_ Q3Chloroform_Report_text.doc
Groundwater QAP and Chloroform QAP, Revision 7.2 were approved by DRC on June
7, 2012.
The sampling methodology, equipment and decontamination procedures that were used
for the chloroform contaminant investigation, as summarized below, are consistent with
the newly approved QAP Revision 7.2 and the Chloroform QAP.
2.2.1 Well Purging and Depth to Groundwater
A list of the wells in order of increasing chloroform contamination is generated quarterly.
The order for purging is thus established., __ The list is included with the Field Data
Worksheets under Tab B. Mill personnel start purging with all of the non-detect wells
and then move to the more contaminated wells in order of chloroform contamination.
Samples are collected by means of disposable bailer(s) the day following the purging.
The disposable bailer is used only for the collection of a sample from an individual well
and disposed subsequent to the sampling. The wells are purged prior to sampling by
means of a portable pump. Each quarterly purging event begins at the location least
affected by chloroform (based on the previous quarters sampling event) and proceeds by
affected concentration to the most affected location. As noted in the approved QAP,
Revision 7.2, purging will generally follow this order, and the sampling order may
deviate slightly from the generated list. This practice does not affect the samples for
these reasons: any wells sampled in slightly different order have either dedicated pumps
or are sampled via a disposable bailer. This practice does not affect the quality or
usability of the data as there will be no cross-contamination resulting from sampling
order.
Before leaving the Mill office, the portable pump and hose are rinsed with deionized
("DI") water. Where portable (non-dedicated) sampling equipment is used, a rinsate
sample will be collected at a frequency of one rinsate sample per 20 field samples. Well
depth measurements are taken and the one casing volume is calculated for those wells
which do not have a dedicated pump as described in Attachment 2-3 of the QAP. Purging
is completed to remove stagnant water from the casing and to assure that representative
samples of formation water are collected for analysis. There are three purging strategies
that will be 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
specific conductivity, turbidity, pH, redox potential, and water temperature
2. Purging two casing volumes with stable field parameters for specific conductivity,
turbidity, pH, redox potential, and water temperature (within 10% RPD)
3. Purging a well to dryness and stability of field parameters for pH, specific
conductivity, and water temperature only after recovery
If the well has a dedicated pump, 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, EFRI will follow the purging
requirements outlined in Attachment 2-3 of the QAP. The dedicated pump is used to
4
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q3\20 12_ Q3Chioroform _Report_text. doc
collect parameters and to collect the samples as described below. If the well does not
have a dedicated pump, a Grundfos pump (9 -10 gpm pump) is then lowered to the
screened interval in the well and purging is started. The purge rate is measured for the
well by using a calibrated 5 gallon bucket. This purging process is repeated at each well
location moving from least contaminated to the most contaminated well. All wells are
capped and secured prior to leaving the sampling location.
Wells with dedicated pumps are sampled when the pump is in the pumping mode. If the
pump is not pumping at the time of sampling, it is manually switched on by the Mill
Personnel. The well is pumped for approximately 5 to 10 minutes prior to the collection
of the field parameters. Per the approved QAP, one set of parameters is collected.
Samples are collected following the measurement of one set of field parameters. The
pump is turned off and allowed to resume its timed schedule.
2.2.2 Sample Collection
Samples are collected as described above. In all cases, on days when samples will be
collected, a cooler with ice is prepared. The trip blank is also gathered at that time (the
trip blank for these events is provided by the Analytical Laboratory). Once Mill
Personnel arrive at the well sites, labels are filled out for the various samples to be
collected. All personnel involved with the collection of water and samples are then
outfitted with rubber gloves. Chloroform investigation samples are collected by means of
disposable bailers.
Mill personnel use a disposable bailer to sample each well that does not have a dedicated
pump. The bailer is attached to a reel of approximately 150 feet of nylon rope and then
lowered into the well. After coming into contact with the water, the bailer is allowed to
sink into the water in order to fill. Once full, the bailer is reeled up out of the well and
the sample bottles are filled as follows:
• Volatile Organic Compound ("VOC") samples are collected first. This sample
consists of three 40 ml vials provided by the Analytical Laboratory. The VOC
sample is not filtered and is preserved with HCI;
• A sample for nitrate/nitrite is then collected. This sample consists of one 250 ml.
bottle which is provided by the Analytical Laboratory. The nitrate/nitrite sample
is also not filtered and is preserved with H2S04;
• A sample for chloride is then collected. This sample consists of one 500 ml.
bottle which is provided by the Analytical Laboratory. The chloride sample is
also not filtered and is not chemically preserved.
After the samples have been collected for a particular well, the bailer is disposed of and
the samples are placed into the cooler that contains ice. The well is then recapped and
Mill personnel proceed to the next well.

All analytical results were provided by Energy Laboratories ("EL"). Table 1 lists the
dates when analytical results were reported to the QA Manager for each sample.
Results from analysis of samples collected for this quarter's chloroform contaminant
investigation are provided under Tab H of this Report. Also included under Tab Hare
the results of analyses for duplicate samples, the DIFB, and rinsate samples for this
sampling effort, as identified in Table 1, as well as results for trip blank analyses required
by the Chloroform QAP.
2.5.2 Regulatory Framework
As discussed in Section 1.0, above, the NOV and requirements of the CAO triggered a
series of actions on EFRI's part. In addition to the monitoring program, EFRI has
equipped five wells with pumps to recover impacted groundwater, and has initiated
recovery of chloroform from the perched zone.
Sections 4 and 5, below, interpret the groundwater level and flow information,
contaminant analytical results, and pump test data to assess effectiveness of EFRI's
chloroform capture program.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The QA Manager performed a QAlQuality Control ("QC") 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 QC review of laboratory methods and
data. Identification of field QC samples collected and analyzed is provided in Section
6
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q3\2012_ Q3 Chloroform_Report_text. doc
3.1. Discussion of adherence to Mill sampling Standard Operating Procedures ("SOPs")
is provided in Section 3.2. Analytical completeness review results are provided in
Section 3.3. The steps and tests applied to check laboratory data QAlQC are discussed in
Sections 3.4.4 through 3.4.9 below.
The analytical laboratory has 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 Tab H. Results of review of the laboratory
QAlQC information are provided under Tab I and are discussed in Section 3.4, below.
3.1 Field QC Samples
The following 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.
Field QC samples for the chloroform investigation program consist of one field duplicate
sample for each 20 samples, a trip blank for each shipped cooler which contains VOCs,
one DIFB and rinsate samples.
During this quarter, two duplicate samples were collected as indicated in Table 1. The
duplicates were sent blind to the analytical laboratory and analyzed for the same
parameters as the chloroform wells.
Three trip blanks were provided by Energy Laboratories and returned with the quarterly
chloroform monitoring samples.
Two rinsate blank samples were collected at a frequency of one rinsate per twenty
samples per QAP Section 4.3.2 and as indicated on Table 1. Rinsate samples were
labeled with the name of the subsequently purged well with a terminal letter "R" added
(e.g. TW 4-7R). The results of these analyses are included with the routine analyses under
TabH.
In addition, one DIFB, while not required by the Chloroform QAP, was collected and
analyzed for the same constituents as the well samples and rinsate blank samples.
3.2 Adherence to Mill Sampling SOPs
On a review of adherence by Mill personnel to the existing sampling SOPs, the QA
Manager observed that QAlQC requirements established in the QAP and Chloroform
QAP were being adhered to.
7
N:\ WMM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q3\20 12_ Q3Chioroform _Report _text. doc
3.3 Analyte Completeness Review
All analyses required by the CAO for chloroform monitoring for the period were
performed.
3.4 Data Validation
The QAP and GWDP identify the data validation steps and data QC checks required for
the chloroform monitoring program. Consistent with these requirements, the QA
Manager performed the following evaluations: a field data QAlQC evaluation, a holding
time check, a receipt temperature check, an analytical method check, a reporting limit
evaluation, a trip blank check, a QAlQC evaluation of sample duplicates, a QC Control
Limit check for analyses and blanks including the DIFB and a rinsate sample check.
Each evaluation is discussed in the following sections. Data check tables indicating the
results of each test are provided under Tab I.
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 measurement of
field parameters based on the requirements discussed in section 2.2.1 above. The purging
technique employed determines the requirements for field parameter measurement and
whether stability criteria are applied. Review of the Depth to Water data confirms that all
depth measurements used for development of groundwater contour maps were conducted
within a five-day period as indicated by the measurement dates in the summary sheet
under Tab D. The results of this quarter's review offield data are provided under Tab I.
Based upon the review of the field data sheets, all wells conformed to the QAP purging
and field measurement requirements. A summary of the purging techniques employed
and field measurements taken is described below:
Purging Two Casing Volumes with Stable Field Parameters (within 10% RPD)
Wells TW4-01, TW4-05, TW4-08, TW4-09, TW4-11, TW4-12, TW4-16, MW-32, TW4-
21, TW4-23, TW4.,.24, and TW4-25 were sampled after two casing volumes were
removed. Field parameters pH, specific conductivity, turbidity, water temperature, and
redox potential were measured during purging. All field parameters for this requirement
were stable within 10% RPD.
Purging a Well to Dryness and Stability of a Limited List of Field Parameters
Wells TW4-2, TW4-3, TW4-6, TW4-7, TW4-10, TW4-13, TW4-14, TW4-22, TW4-26,
and TW4-27 were pumped to dryness before two casing volumes were evacuated. After
well recovery, one set of measurements for the field parameters of pH, specific
conductivity, and water temperature only were taken, the samples were collected, and
another set of measurements for pH, specific conductivity, and water temperature were
taken. Stabilization of pH, conductivity and temperature are required within 10% RPD
under the QAP, Revision 7.2. It is important to note that redox potential and turbidity
8
N:\ WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q3\2012 _ Q3Chioroform _ Report_text. doc
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.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water to the nearest 0.01 foot.
The revie\-v of the field sheets for compliance with QAP, 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.
Wells TW4-01, TW4-02, TW4-05, TW4-06, TW4-07, TW4-08, TW4-09, TW4-10,
TW4-11, TW4-12, TW4-16, MW-32, TW4-18, TW4-21, TW4-23, TW4-24, TW4-25,
TW4-26, and TW4-27 exceeded the QAP's 5 NTU goal. The QAP does not require that
turbidity measurements be less than 5 NTU prior to sampling. Of the nineteen samples,
six samples (TW4-02, TW4-06, TW4-07, TW4-10, TW4-26, and TW4-27) were taken
after the well had been pumped to dryness. In wells that are purged to dryness, turbidity
is not required per the QAP, Revision 7.2. As such, the noted observations regarding
turbidity measurements less than 5 NTU are included for information purposes only.
EFRI'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, EFRI has completed a
monitoring well redevelopment program. The redevelopment report was submitted to
DRC on September 30, 2011. DRC responded to the redevelopment report via letter on
November 15, 2012. Per the DRC letter dated November 15, 2012, the field data
generated this quarter are compliant with the turbidity requirements of the approved
QAP.
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 in Tab I. The Trip Blank sample collected on
9110/2012 was analyzed by the laboratory outside of the required holding time. The
samples were received at the lab on 9/14/2012, but were not analyzed until 9/26/2012. All
other samples received by the laboratory with the Trip Blank were analyzed within
required holding time. EFRI Field Personnel shipped the samples, and they were received
by the laboratory with more than sufficient time to analyze the samples within required
holding time. This is due to a laboratory error and did not result from any actions or
inactions EFRI. Not only was EFRI not informed of the missed holding time by the
laboratory, the original data p'ackage sent from the laboratory did not flag the sample as
being outside required holding time. It was not until EFRI's manual QAlQC evaluation
9
N:\ WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\20 12 Q3\20 12_ Q3 Chloroform_Report _text. doc
that the issue was identified.
Corrective actions for this issue are described in Section 6.1.
3.4.3 Receipt Temperature Evaluation
Chain of Custody sheets were reviewed to confirm compliance with the QAP requirement
which specifies that samples be received at 6°C or lower. Sample temperatures checks
are provided in Tab I. All samples were received within the required temperature limit.
3.4.4 Analytical Method Checklist
All analytical methods reported by the laboratory were checked against the required
methods enumerated in the Chloroform QAP. Analytical method checks are provided in
Tab I. All methods were consistent with the requirements of the Chloroform QAP.
3.4.5 Reporting Limit Evaluation
All analytical method reporting limits reported by the laboratory were checked against
the reporting limits enumerated in the Chloroform QAP. Reporting Limit Checks are
provided under Tab I. All analytes were measured and reported to the required reporting
limits, except 30 sets (28 samples and 2 duplicates) of 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.
3.4.6 Receipt pH Evaluation
Appendix A of the QAP states that all volatile samples are required to be preserved and
arrive at the laboratory with a pH less than 2. A review of the laboratory data revealed
that all volatile samples were received at the laboratory with a pH less than 2 except for
one, TW4-24. In past cases where a sample was outside of acceptable pH limits, the
laboratory notified EFRI at the time of analysis so that a new sample could be collected;
however in this case, EFRI was not informed of the issue by the laboratory at the time of
analysis. The sample was not recollected, because EFRI became aware of the issue after
the end of the third quarter.
The laboratory noted the pH of the sample from TW 4-24 was 5 at the time of analysis.
This would indicate that the sample was not preserved. Per EPA SW-846 Chapter 4,
Organic Analytes, Section 4.1.2, the standard holding time for a preserved VOC sample
is 14 days, and the standard holding time for a non-preserved VOC sample is 7 days. The
analysis was completed by the laboratory within 7 days per the EPA standard for a non-
preserved sample, rather than the 14 days as required by the QAP. Since the sample was
analyzed within EPA required hold time for non-preserved samples, the data are useable
and not rej ected.
" Corrective actions for this issue are described in Section 6.1.

3.4.7 Trip Blank Evaluation
All trip blank results were reviewed to identify any VOC contamination resulting from
transport of the samples. Trip blank checks are provided in Tab 1. All trip blank results
were less than the reporting limit for all VOCs.
3.4.8 QAlQC Evaluation for 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 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 reported detection limit
and the RPD is greater than 20%. The additional duplicate information is provided for
information purposes.
All analytical results for the sample/duplicate pairs were within the 20% acceptance
limits except one. The chloroform result for the parent sample, TW4-25, was non-detect,
while the duplicate sample, TW 4-70, result was 1.3 ug/L resulting in an RPD greater the
20%. However, per section 9.1.4 a) of the QAP, sample duplicates will be considered
noncompliant only when the results are greater than 5 times the required reporting limit
and the RPD is greater than 20%. The sample/duplicate results in this case are not greater
than 5 times the reporting limit and therefore are considered acceptable. All results of the
RPD test are provided in Tab 1.
3.4.9 Rinsate Sample Check
Rinsate blank sample checks are provided in Tab 1. A comparison of the rinsate blank
sample concentration levels to the QAP requirements -that rinsate sample concentrations
be one order of magnitude lower than that of the actual well -indicated that all of the
rinsate blank analytes met this criterion.
While not required by the Chloroform QAP, DIFB samples are collected to analyze the
quality of the DI water system at the Mill, which is also used to collect rinsate samples. A
review of the analytical results reported for the DIFB sample indicated the sample
contained chloroform. Further review of the data package showed that the DIFB sample
was analyzed by the lab immediately after the samples with the highest levels of
chloroform. As the rinsates collected for the quarter are non-detect, EFRI believes the
chloroform present in the DIFB is due to carry-over at the lab and does not represent
actual chloroform contamination in the DI water system at the Mill. No formal corrective
action will be provided, however, EFRI is planning to change laboratories for the first
Quarter 2013 sampling event.

3.4.10 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,
EFRI'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-specified acceptance limits, or that the case narrative sufficiently
explains any deviation from these limits. Results of this quantitative check are provided
in Tab I.
All lab QAlQC results met these specified acceptance limits except as noted below.
The QAP Section 8.1.2 requires that a Matrix Spike/Matrix Spike Duplicate
("MS/MSD") pair be analyzed with each analytical batch. The QAP does not specify
acceptance limits for the MS/MSD pair, and the QAP does not specify that the MS/MSD
pair be prepared on EFRI samples only. Acceptance limits for MS/MSDs are set by the
laboratories. The review of the information provided by the laboratories in the data
packages verified that the QAP requirement to analyze an MS/MSD pair with each
analytical batch was met. While the QAP does not require it, the recoveries were
reviewed for compliance with the laboratory established acceptance limits. The QAP
does not require this level of review, and the results of this review are provided for
information only.
The information from the Laboratory QAlQC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all quarterly chloroform samples are
within acceptable laboratory limits for all regulated compounds except as indicated in
Tab I. One MS/MSD recovery RPD was are outside the laboratory established acceptance
limits. This result does 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. Fourteen MS/MSD recoveries were above the laboratory established
acceptance limits, indicating a high bias to the individual sample results. A high bias
means that reported results may be higher than the actual results. One MS/MSD recovery
was below the laboratory established acceptance limits. The lab noted on this MS/MSD
that the target compound matrix carryover from previous samples caused interference for
the chloroform recoveries. The recoveries do not affect the quality or usability of the data
because the recoveries outside of the acceptance limits are indicative of matrix
interference. The QAP requirement to analyze a MS/MSD pair with each analytical batch
was met and as such the data are compliant with the QAP.
The QAP specifies that surrogate compounds shall be employed for all organic analyses,
but the QAP does not specify acceptance limits for surrogate recoveries. The analytical
data associated with the routine quarterly sampling met the requirement specified in the
QAP. The information from the Laboratory QAlQC Summary Reports indicates that the
12
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q3\2012_Q3Chloroform_Report_text.doc
surrogate recoveries for all quarterly chloroform samples were within acceptable
laboratory limits for all surrogate compounds except as indicated in Tab 1. One hundred
and one surrogate recoveries were above the laboratory established acceptance limits,
indicating a high bias to the individual sample results. A high bias means that reported
results may be higher than the actual results. One surrogate recovery was below the
laboratory established acceptance limits. The surrogate compounds outside of acceptance
limits are most likely the result of laboratory spiking compound degradation. This is
apparent because the same compounds were outside the 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 the low surrogate recoveries were on a laboratory matrix spike which
would indicate surrogate solution degradation at the laboratory. These recoveries do not
impact other results, because there are multiple surrogates added to each sample and all
other surrogates were within limits. Furthermore, there are no QAP requirements for
surrogate recoveries.
The information from the Laboratory QAlQC Summary Reports indicates that all LCS
recoveries were within acceptable laboratory limits for all LCS compounds except as
indicated in Tab 1. There were five LCS recoveries which were above the laboratory
established acceptance limits, 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.
4.0 INTERPRETATION OF DATA
4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions.
4.1.1 Current Site Groundwater Contour Map
As stated above, a listing of groundwater level readings for the current quarter (shown as
depth to groundwater in feet) is included under Tab D. The data from this tab has been
interpreted (kriged) and plotted in a water table contour map, provided under the same
tab.
Also included under Tab D is a groundwater contour map of the Mill site and a more
detailed map of a portion of the Mill site where the chloroform pumping wells are
located, in each case with hand-drawn stream tubes, depicting hydraulic capture from the
pumpIng.
The water level contour maps indicate that perched water flow ranges from generally
southwesterly beneath the Mill site and tailings cells to generally southerly along the
eastern and western margins of White Mesa. Perched water mounding associated with the
wildlife ponds locally changes the flow patterns. For example, northeast of the Mill site,
mounding associated with wildlife ponds results in locally northerly flow near MW -19.
The impact of the water level mound associated with the northern ponds, which are no
longer receiving water, is diminishing and is expected to continue to diminish in the
future as the water level mound decays due to reduced recharge. Flow directions are also
locally influenced by pumping at MW-4, MW-26, TW4-4, TW4-19, and TW4-20.

N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q3\2012_ Q3Chloroformyeport_text.doc
Significant cones of depression have formed in the vicinity of all pumping wells except
TW4-4, which began pumping in the first quarter of2010.
Although pumping at TW4-4 has depressed the water table in the vicinity of TW4-4, a
well-defined cone of depression is not evident. The lack of a well-defined cone of
depression likely results from 1) variable permeability conditions in the vicinity of TW 4-
4, and 2) persistent relatively low water levels at adjacent well TW 4-14.
Changes in water levels at wells immediately south of TW 4-4 resulting from TW 4-4
pumping are expected to be muted because TW 4-4 is located at a transition from
relatively high to relatively low permeability conditions south (downgradient) of TW4-4.
The permeability of the perched zone at TW4-6 and TW4-26 is approximately two orders
of magnitude lower than at TW 4-4. Any drawdown of water levels at wells immediately
south of TW 4-4 resulting from TW 4-4 pumping is also difficult to determine because of a
general, long-term increase in water levels in this area. Water levels at TW4-4 and TW4-
6 increased by nearly 2.7 and 2.9 feet, respectively, between the fourth quarter of 2007
and the fourth quarter of 2009 Gust prior to TW 4-4 pumping) at rates of approximately
1.2 feet/year and 1.3 feet/year, respectively. However, the increase in water level at TW4-
6 has been reduced since the start of pumping at TW 4-4 (first quarter of 2010) to less
than 0.5 feet/year suggesting that TW4-6 is within the hydraulic influence of TW4-4.
The lack of a well-defined cone of depression at TW 4-4 is also influenced by the
persistent, relatively low water level at non-pumping well TW 4-14, located east of TW 4-
4 and TW4-6. For the current quarter, the water level at TW4-14 (approximately 5526
feet above mean sea level [ft amsl]) is approximately 13 feet lower than the water level
at TW4-6 (approximately 5539 ft amsl) and approximately 17 feet lower than at TW4-4
(approximately 5543 ft amsl) even though TW4-4 is pumping.
Well TW4-27 (installed south of TW4-14 in the fourth quarter of2011) has a static water
level of approximately 5526 ft amsl, similar to TW4-14. TW4-27 was positioned at a
location considered likely to detect any chloroform present and/or to bound the
chloroform plume to the southeast and east of TW 4-4 and TW 4-6. As will be discussed
below, groundwater data collected since installation indicates that TW4-27 does indeed
bound the chloroform plume to the southeast and east of TW 4-4 and TW 4-6.
Prior to the installation of TW4-27, the persistently low water level at TW4-14 was
considered anomalous because it appeared to be downgradient of all three wells TW4-4,
TW4-6, and TW4-26, yet chloroform was not detected at TW4-14. Chloroform had
apparently migrated from TW4-4 to TW4-6 and from TW4-6 to TW4-26 which
suggested that TW 4-26 was actually downgradient of TW 4-6, and TW 4-6 was actually
downgradient of TW 4-4, regardless of the flow direction implied by the low water level
at TW4-14. The water level at TW4-26 (5538.6 feet amsl) is, however, lower than water
levels at adjacent wells TW4-6 (5539.0 feet amsl), and TW4-23 (5542.9 feet amsl)
Hydraulic tests conducted in November, 2011 indicate that the permeability at TW4-27 is
an order of magnitude lower than at TW 4-6 and three orders of magnitude lower than at
TW4-4. The similar water levels at TW4-14 and TW4-27, and the low permeability
estimate at TW4-27 suggest that both wells are completed in materials having lower
14
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q3\2012_ Q3Chloroform_Report_text.doc
permeability than nearby wells. The low permeability condition likely reduces the rate of
long-term water level increase at TW4-14 and TW4-27 compared to nearby wells,
yielding water levels that appear anomalously low. The low permeability condition is
expected to retard the transport of chloroform to TW4-14 and TW4-27 (compared to
nearby wells). As will be discussed in Section 4.2.3, third quarter, 2012 chloroform
concentrations at TW 4-26 and TW 4-27 are 6.9 ug/L and non-detect, respectively and
both wells are outside the chloroform plume.
4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater
Contour Maps for Previous Quarter
The groundwater contour maps for the Mill site for the second quarter of 2012, as
submitted with the Chloroform Monitoring Report for the second quarter of 2012, are
attached under Tab E.
A comparison of the water table contour maps for the current (third) quarter of 2012 to
the water table contour maps for the previous quarter (second quarter of 2012) indicates
similar patterns of drawdown related to pumping of MW -4, MW -26, TW 4-4, TW 4-19
and TW4-20. Water levels and water level contours for the site have not changed
significantly since the last quarter, except for a few locations. As discussed in Section
4.1.1, pumping at TW4-4, which began in the first quarter of 2010, has depressed the
water table near TW4-4, but a well-defined cone of depression is not yet evident, likely
due to variable permeability conditions near TW 4-4 and the persistently low water level
at adjacent well TW4-14.
Reported increases in water level of approximately 3 feet occurred in well MW-20 and of
approximately 6 feet occurred in well TW 4-12, and decreases of approximately 6 feet
occurred in PIEZ-2, and of approximately 3 feet occurred in TWN-2. The water level
change at PIEZ-2 is consistent with the cessation of water delivery to the northern
wildlife ponds. The water level changes at other non-pumping wells were less than 3 feet.
A water level decrease (increase in drawdo~) of nearly 7 feet occurred in pumping well
MW-26.
Water level fluctuations at pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-
20 typically occur in part because of fluctuations in pumping conditions just prior to and
at the time the measurements are taken. Water levels reported at all pumping wells other
than MW-26 this quarter were within 2 feet of their reported water levels last quarter.

4.1.5 Evaluation of the Effectiveness of Hydraulic Capture
Perched water containing chloroform has been removed from the subsurface by pumping
MW-4, MW-26, TW4-4, TW4-19, and TW4-20. The primary purpose of the pumping is
to reduce total chloroform mass in the perched zone as rapidly as is practical. Wells
upgradient of TW 4-4 were chosen for pumping because 1) they are located in areas of the
perched zone having relatively high permeability and saturated thickness, and 2) high
concentrations of chloroform were detected at these locations. The relatively high
transmissivity of the perched zone in the vicinity of these pumping wells results in the
wells having a relatively high productivity. The combination of relatively high
productivity and high chloroform concentrations allows a high rate of chloroform mass
removal. TW 4-4 is located in a downgradient area having relatively high chloroform
concentrations but relatively small saturated thickness, and at a transition from relatively
high to relatively low permeability conditions downgradient of TW 4-4. As with the other
pumping wells, pumping TW 4-4 helps to reduce the rate of chloroform migration in
downgradient portions of the plume.
The impact of pumping is indicated by the water level contour maps attached under Tabs
D and E. Cones of depression have developed in the· vicinity of MW -4, MW -26, TW 4-
19, and TW4-20 which continue to remove significant quantities of chloroform from the
perched zone. The water level contour maps indicate effective capture of water
containing high chloroform concentrations in the vicinities of these pumping wells.
Overall, the combined capture of MW-4, MW-26, TW4-19, and TW4-20 has not changed
significantly since the last quarter. As discussed in Section 4.1.1, the drawdown
associated with TW 4-4 is likely less apparent due to variable permeability conditions
near TW4-4 and the persistently low water level at adjacent well TW4-14.
Chloroform concentrations exceeding 70 ~g/L have occurred in the past at some
locations downgradient of pumping wells (for example, at TW4-6, located immediately
south of TW4-4), where the lower permeability and relatively small saturated thickness
of the perched zone significantly limits the rate at which chloroform mass can be
removed by pumping. By removing mass and reducing hydraulic gradients, thereby
reducing the rate of downgradient chloroform migration, and allowing natural attenuation
to be more effective, pumping at the productive, up gradient locations has a beneficial
effect on this downgradient chloroform. Pumping at TW 4-4 was implemented during the
first quarter of 2010 to improve capture in this downgradient area to the extent allowable
by the lower productivity conditions presumed to exist in this area. The beneficial effect
of pumping TW 4-4 is demonstrated by the decrease in chloroform concentrations at
TW4-6 from 1000 ~g/L to 6.9 ~g/L, and at TW4-26 from 13 ~g/L to 4.9 ~g/L since
pumping began at TW 4-4. Concentrations at these wells have decreased substantially
even though they do not unambiguously appear to be within the hydraulic capture of
TW 4-4. As discussed in Section 4.1.1, however, the decrease in the long-term rate of
water level rise at TW 4-6 since pumping began at TW 4-4 does suggest that TW 4-6 is
within the hydraulic influence of TW4-4. Regardless of whether TW4-6 can be
demonstrated to be within hydraulic capture of TW 4-4, pumping TW 4-4 reduces
chloroform migration to TW 4-6 and TW 4-26 by the mechanisms discussed above.

4.2 Review of Analytical Results
4.2.1 Current Chloroform Isoconcentration Map
Included under Tab J of this Report is a current chloroform isoconcentration map for the
Mill site.
4.2.2 Chloroform Concentration Trend Data and Graphs
Attached under Tab K are tables summarizing values for all required parameters,
chloride, nitrate/nitrite, carbon tetrachloride, chloroform, chloromethane, and methylene
chloride, for each well over time.
Attached under Tab L are graphs showing chloroform concentration trends in each
monitor well over time.
4.2.3 Interpretation of Analytical Data
Comparing the analytical results to those of the previous quarter, as summarized in the
table included under Tab K, the following observations can be made:
a) Chloroform concentrations have increased by more than 20% in the following
wells compared to last quarter: MW-26, TW4-S, TW4-6, TW4-10, TW4-18,
TW4-19 and TW4-22;
b) Chloroform concentrations have decreased by more than 20% in the following
well compared to last quarter: TW4-20;
c) Chloroform concentrations have remained within 20% in the following wells
compared to last quarter: MW-4, TW4-1, TW4-2, TW4-4, TW4-7, TW4-11,
TW 4-21, and TW 4-26;
d) MW-32, TW4-3, TW4-8, TW4-9, TW4-12, TW4-13, TW4-14, TW4-16, TW4-
23, TW4-2S and TW4-27 remained non-detect; and
e) Chloroform concentrations at TW 4-24 increased from non-detect to 1.1 ~g/L.
As indicated, chloroform concentrations at many of the wells with detected chloroform
were within 20% of the values reported for the wells during the previous quarter,
suggesting that variations are within the range typical for sampling and analytical error.
Wells MW-26, TW4-S, TW4-6, TW4-10, TW4-18, TW4-19, TW4-20, and TW4-22 had
changes in concentration greater than 20%. Of the latter, MW-26, TW4-19, and TW4-20
are pumping wells. TW4-7 is located adjacent to pumping well MW-4; TW4-10 is
located adjacent to pumping well MW-26; TW4-S and TW4-22 are located adjacent to
pumping well TW4-20; TW4-18 is located adjacent to pumping well TW4-19; and TW4-
6 is located adjacent to pumping well TW4-4. Fluctuations in concentrations at pumping
wells and wells adjacent to pumping wells likely result in part from changes in pumping.
17
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q3\20 12_ Q3Chloroform _ Report_text.doc
Pumping well TW 4-20 had the highest detected chloroform concentration. Since the last
quarter, the chloroform concentration in TW4-20 decreased from 36,000 J,!g/L to 13,000
J,!g/L, the concentration in adjacent pumping well TW4-19 increased from 460 J,!g/L to
950 J,!g/L, the concentration in nearby well TW4-21 increased slightly from 400 to 410
J,!g/L, and the concentration in nearby well TW4-22 increased from 120 J,!g/L to 940
J,!g/L. Wells TW4-23 and TW4-25 remained non-detect for chloroform. The
concentration in well TW 4-24 increased from non-detect to 1.1 J,!g/L. TW 4-24, located
west of TW4-22, and TW4-25, located north of TW4-21 , bound the chloroform plume to
the west and north. In addition, the southernmost boundary of the plume remains between
TW 4-4 and TW 4-6 (located just north of southernmost temporary well TW 4-26).
The chloroform concentration in TW4-6 increased from 4.7 J,!g/L to 6.9 J,!g/L, and
remains outside the chloroform plume boundary. Concentrations at TW4-6 have, since
initiation of pumping of TW 4-4 in the first quarter of 2010, decreased from 1000 J,!g/L to
6.9 J,!g/L. TW 4-6, installed in the second quarter of 2000, was the most downgradient
temporary perched well prior to installation of temporary well TW4-23 in 2007 and
temporary well TW4-26 in the second quarter of 2010. TW4-6 remained outside the
chloroform plume between the second quarter of 2000 and the fourth quarter of 2008.
TW 4-6 likely remained outside the chloroform plume during this time due to a
combination of 1) slow rates of downgradient chloroform migration in this area due to
low permeability conditions and the effects of upgradient chloroform removal by
pumping, and 2) natural attenuation. Because TW 4-6 is again outside the plume
boundary, TW4-6 and TW4-23 bound the chloroform plume to the south. TW4-8, TW4-
12, TW4-13, TW4-14, and TW4-27 bound the chloroform plume to the east.
The slow rate of chloroform migration in the vicinity of TW 4-6 is demonstrated by
comparing the rate of increase in chloroform at this well to the rate of increase in the
nearest upgradient well TW 4-4. Concentrations at TW 4-4 increased from non-detect to
more than 2,200 J,!g/L within only 2 quarters whereas 16 quarters were required for
concentrations in TW 4-6 to increase from non-detect to only 81 J,!g/L. This behavior is
consistent with hydraulic tests performed at TW4-4, TW4-6, and TW4-26 during the
third quarter of 2010 that indicate a nearly two order of magnitude decrease in
permeability downgradient of TW 4-4. Chloroform migration rates in the vicinity of well
TW4-26 and new well TW4-27 are also expected to be relatively low due to upgradient
pumping and low permeability conditions.
5.0 LONG TERM PUMP TEST AT MW-4, MW-26, TW4-19, TW4-20, AND
TW4-4 OPERATIONS REPORT
5.1 Introduction
As a part of the investigation of chloroform contamination at the Mill site, EFRI has been
conducting a Long Term Pump Test on MW-4, TW4-19, MW-26, and TW4-20, and,
since January 31, 2010, TW4-4. The purpose of the test is to serve as an interim action
that will remove a significant amount of chloroform-contaminated water while gathering
additional data on hydraulic properties in the area of investigation. The following
information documents the operational activities during the quarter.

N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q3\2012_ Q3Chloroform_Report_text.doc
5.2 Pump Test Data Collection
The long term pump test for MW-4 was started on April 14, 2003, followed by the start
of pumping from TW4-19 on April 30, 2003, from MW-26 on August 8, 2003, from
TW4-20 on August 4, 2005, and from TW4-4 on January 31, 2010. Personnel from
Hydro Geo Chern, Inc. were on site to conduct the first phase of the pump test and collect
the initial two days of monitoring data for MW-4. EFRI personnel have gathered
subsequent water level and pumping data.
Analyses of hydraulic parameters and discussions of perched zone hydrogeology near
MW-4 has been provided by Hydro Geo Chern in a separate report, dated November 12,
2001, and in the May 26,2004 Final Report on the Long Term Pumping Test.
Data collected during the quarter included the following:
• Measurement of water levels at MW-4, TW4-19, MW-26, and TW4-20
and, commencing regularly on March 1,2010, TW4-4, on a weekly basis,
and at selected temporary wells and permanent monitoring wells on a
monthly basis.
• Measurement of pumping history, including:
pumping rates
total pumped volume
operational and non-operational periods.
• Periodic sampling of pumped water for chloroform and nitrate/nitrite
analysis and other constituents
5.3 Water Level Measurements
Beginning August 16, 2003, the frequency of water level measurements from MW-4,
MW-26, and TW4-19 was reduced to weekly. From commencement of pumping TW4-
20, and regularly after March 1, 2010 for TW 4-4, water levels in these wells have been
measured weekly. Depth to groundwater in all other chloroform contaminant
investigation wells is monitored monthly. Copies of the weekly Depth to Water
monitoring sheets for MW-4, MW-26, TW4-19, TW4-20 and TW4-4 and the monthly
Depth to Water monitoring sheets for all of the chloroform contaminant investigation
wells are included under Tab C. Monthly depth to water measurements for the quarter
are recorded in the Field Data Worksheets included under Tab D.
5.4 Pumping Rates and Volumes
Table 2 summarizes the recovered mass of chloroform by well per quarter and
historically since the inception of the chloroform recovery program for the five currently-
active pumping wells.
All of the pumping wells do not pump continuously, but are on a delay device. The wells
purge for a set amount of time and then shut off to allow the well to recharge. Water
from the pumping wells is transferred to the Cell 1 evaporation pond through a pipeline
19
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\20 12 Q3\20 12_ Q3Chioroform _ Report_text.doc
installed specifically for that purpose. The pumping rates and volumes for each of the
pumping wells are shown in Table 3. No operational problems were observed with the
well or pumping equipment during the quarter.
5.5 Mass Removed
Chloroform removal was estimated as of the first quarter 2007. Since that estimation the
mass removed by well for each quarter has been compiled in Table 2, indicating that a
total of 614.00 pounds of chloroform have been removed to date.
5.6 Inspections
EFRI has submitted an Operations and Maintenance Plan, Chloroform Pumping System,
White Mesa Mill, Blanding, Utah, Revision 2.1 which includes a proposed weekly
inspection form to UDEQ for approval on October 25,2010. Upon approval of that plan,
the Mill will commence documenting its required inspections of the operational status of
the chloroform pumping wells on the proposed weekly inspection form. Completed
inspections for the quarter, recorded on the approved weekly inspection form, will be
included in future Chloroform reports upon approval by UDEQ. At the time of the
publication of this report, approval of the Operations and Maintenance Plan, Chloroform
Pumping System, White Mesa Mill, Blanding, Utah, Revision 2.1 had not been received.
As mentioned above, there were no operational problems in the pumping wells this
period.
5.7 Conditions That May Affect Water Levels in Piezometers
There no water was added to the any of the wildlife ponds during the quarter.
6.0 CORRECTIVE ACTION REPORT
Necessary corrective actions identified during the current monitoring period are described
below.
Identification and Definition of the Problem
TW4-24 receipt pH
Appendix A of the QAP states that all VOC samples are required to be preserved and
arrive at the laboratory with a pH less than 2. A review of the laboratory data revealed
that all VOC samples were received at the laboratory with a pH less than 2 except for
one, TW4-24. EFRI was not informed of the issue by the laboratory at the time of
analysis. The sample was not recollected, because EFRI became aware of the issue after
the end of the second quarter. The laboratory noted the pH was 5 at the time of analysis.
It is important to note that the EPA standard holding time for non-preserved VOCs is 7
days. The analysis of TW4-24 was completed by the laboratory within 7 days, which is
within the EPA standard hold time for a non-preserved sample. Since the sample was
analyzed within EPA required hold time for non-preserved samples, the data are not
rejected.
20
N:\ WMM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q3\20 12_ Q3Chioroform _Report _text. doc
A similar corrective action was identified in the second quarter 2012 sample event. EFRI
was able to identify that Field Personnel inadvertently omitted the laboratory-provided
preservative, and the issue was addressed with Field Personnel and corrected. Further
investigation into the issue showed that the pH of TW 4-24 at the time of sample
collection was 6.71. For the laboratory to have received that sample with a pH of 5 would
indicate that there was preservative present in the sample bottle. The preservative
provided to EFRI Field Personnel is made at and shipped by the laboratory. As this is not
the first issue with sample receipt pH, EFRI believes the issue is due to inconsistent
preparation of the preservative by the laboratory and is not due to an error by EFRI Field
Personnel.
Trip Blank Holding Times
One of the three trip blanks analyzed during the third quarter of 2012 was outside of the
required holding time. All other samples received with the trip blank were analyzed
within the required holding time and as such the data are not rejected. The samples
arrived at the laboratory with more than sufficient time to analyze all of the samples
within the required holding time, and therefore EFRI believes this to be a laboratory
error. EFRI was not informed by the laboratory of the holding time issue, and the data
package sent to EFRI by the laboratory also did not identify the issue. It was not until
EFRI's manual review of holding times that the problem was identified.
Assignment of Responsibility for Investigation of the Problem
Both problems have been investigated by the QA Manager.
Investigation and Determination of Cause of the Problem
TW4-24 receipt pH
As discussed above, the sample TW4-24 was received by the laboratory with a pH of 5,
which is above the QAP required limit of 2. After further investigation, EFRI believes the
issue of sample receipt pH is due to inconsistent preparation of the preservative by the
laboratory. All other samples were received within acceptable pH levels indicating this is
an isolated issue for this one sample. This issue has occurred in the past, and EFRI Field
Personnel have been made aware, and actions have been taken to eliminate this problem.
As such, EFRI has determined the issue of sample preservation resulted from the source
of the preservative, which is the current laboratory.
Trip Blank Holding Times
As discussed above, the Trip Blank sample collected on 911 0/20 12 was analyzed by the
laboratory outside of the required holding time. In a review of the data, EFRI determined
the Trip Blank was received by the laboratory on 9114/2012 and not analyzed until
9/26/2012; which resulted in the data being outside the required holding time.
21
N:\ WMM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q3\20 12_ Q3Chioroform _Report _text. doc
Determination of a Corrective Action to Eliminate the Problem
TW4-24 receipt pH
The sample which was received at the laboratory with a pH greater than 2 is the result of
inconsistent preparation of sample preservative by the laboratory. EFRI has initiated an
investigation into contracting an alternative laboratory and expects to make the change
for the 1 st quarter 2012 sampling event.
Trip Blank Holding Times
The Trip Blank sample, which was analyzed outside of required holding time, was a
result of a laboratory error. The samples were received with more than sufficient time to
analyze all samples within the required holding time. EFRI has determined this issue is
due to laboratory error and not due to any actions or inactions by EFRI. As discussed
above, EFRI has initiated contract negotiations with an alternate Utah certified analytical
laboratory and expects to make the change for the 1 st quarter 2012 sampling event.
Assigning and Accepting Responsibility for Implementing the Corrective Action
TW 4-24 receipt pH & Trip Blank Holding Times
It will be the responsibility of the QA manager to review data from the alternate Utah
certified laboratory to assure completion of analysis within the method specified holing
times.
Implementing the Corrective Action and Evaluating Effectiveness
TW 4-24 receipt pH & Trip Blank Holding Times
EFRI has contacted the current laboratory to make them aware of the issues. In addition,
EFRI has initiated the process to find and change analytical laboratories. The change to a
new analytical laboratory is expected to occur prior to the 1 st quarter 2013 sampling
event. Once a new laboratory is identified, the sample receipt data will be assessed as
samples are received at the new laboratory to determine if any further action is necessary.
Verifying That the Corrective Action Has Eliminated the Problem
TW 4-24 receipt pH & Trip Blank Holding Times
Verification that samples are analyzed within the required holding time, and are received
at the laboratory with a pH less than 2, will occur during the assessment of data collected
from the first quarter 2013 sampling event.
6.1 Assessment of Previous Quarter's Corrective Actions
Chloroform was present in the rinsate blanks and chloride was present in the DIFB during
the second quarter 2012. To address previous nitrate contamination in the nitrate and
chloroform sampling programs, an additional rinse with 55-gallons of DI water has been
added to the decontamination process. The nitrate contamination has been eliminated
from rinsate blanks, however, the addition of 55-gallons of DI water has resulted in
chloride contamination in rinsates and DIFBs.
22
N: \ WMM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q3\20 12_ Q3Chioroform _Report _text. doc
The new rinsate requirements under QAP, Revision 7.2, lower the frequency which field
personnel collect rinsate samples and allows the DI system to recover. The lower rinsate
frequency resulted in no rinsate contamination during the third quarter of 2012. The
DIFB for the third quarter of 2012 indicated chloroform was present in the sample,
however, EFRI has determined this result is due to laboratory carryover and is not
representative of actual contamination in the DI water system. EFRI is making
arrangements to contract another laboratory. Rinsate and DIFB data will be reviewed to
determine if additional corrections are necessary.
f
Verification that rinsate and DIFB contamination has been eliminated will occur upon
completion of the system upgrades and receipt of at least the two quarters of data. If
contamination persists then additional sources will be researched and the investigation
will continue.
The corrective actions for the second quarter of 2012 also discussed a rinsate sample
which was received by the laboratory with a pH greater than acceptable limits. The third
quarter of 2012 showed all rinsate samples were received at acceptable limits. However,
the sample TW4-24 for the third quarter 2012 sampling event was received by the
laboratory with a pH of S. EFRI has investigated this issue and has determined that Field
Personnel followed all corrective actions identified during the second quarter of 2012,
and the issue is related to inconsistent laboratory preparation of the acid preservative that
is provided by the laboratory. These inconsistencies, along with other recurring issues
from the current laboratory, have prompted EFRI to find a new laboratory. This change is
expected to be implemented for the 1 st quarter 2013 sampling event.
7.0 CONCLUSIONS AND RECOMMENDATIONS
The water level contour maps for the third quarter, 2012 indicate effective capture of
water containing high chloroform concentrations in the vicinity of pumping wells MW -4,
MW-26, TW4-19, and TW4-20. A well-defined capture zone is not evident at TW4-4.
The capture zone associated with TW 4-4 is likely obscured by the low water level at
adjacent well TW 4-14 and the two orders of magnitude decrease in permeability south of
TW 4-4. However, the decrease in chloroform concentrations at TW 4-6 (located
downgradient of TW 4-4) since the fourth quarter of 2009 is likely related to TW 4-4
pumpIng.
Third quarter, 2012 chloroform concentrations at many of the wells with detected
chloroform were within 20% of the values reported during the previous quarter,
suggesting that variations are within the range typical for sampling and analytical error.
Changes in concentration greater than 20% occurred in wells MW-26, TW4-S, TW4-6,
TW4-10, TW4-18, TW4-19, TW4-20, and TW4-22; the concentration in well TW4-27
remained non-detect.
Of the wells showing changes in concentration greater than 20%, MW-26, TW4-19, and
TW4-20 are pumping wells. TW4-7 is located adjacent to pumping well MW-4; TW4-10
is located adjacent to pumping well MW-26; TW4-S and TW4-22 are located adjacent to
pumping well TW4-20; TW4-18 is located adjacent to pumping well TW4-19; and TW4-
6 is located adjacent to pumping well TW4-4. Fluctuations in concentrations at pumping
23
N:\ WJ'vlM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q3\20 12_ Q3Chioroform _Report _text. doc
wells and wells adjacent to pumping wells likely result in part from changes in pumping.
Between the current and previous quarters, the concentration in TW4-26, which is the
most downgradient temporary well, increased slightly from 4.1 f.lg/L to 4.9 f.lg/L. The
changes in concentrations at TW4-6 and TW4-26 are likely the result of their location
near the downgradient edge of the plume where changes in upgradient pumping are
expected to affect concentrations.
The highest chloroform concentration (13,000 f.lg/L) was detected at pumping well TW4-
20. Since the last quarter, the chloroform concentration in TW4-20 decreased from
36,000 f.lg/L to 13,000 f.lg/L, the concentration in adjacent pumping well TW4-19
increased from 460 f.lg/L to 950 f.lg/L, the concentration in nearby well TW4-21 increased
slightly from 400 to 410 f.lg/L, and the concentration in nearby well TW4-22 increased
from 120 f.lg/L to 940 Jlg/L Fluctuations in concentrations in these wells are likely related
to their location near the suspected former office leach field source area in addition to
variations in pumping in TW4-20 and nearby wells. Regardless of these measured
fluctuations in chloroform concentrations, sampling of temporary wells TW 4-24 (located
west of TW4-22) and TW4-25 (located north of TW4-21), indicates these wells remain
outside the chloroform plume and thus bound the plume to the west and north.
Chloroform was not detected at TW 4-25 and was detected at a concentration of 1.1 f.lg/L
at TW4-24.
The chloroform concentration at well TW4-6 increased from 4.7 f.lg/L to 6.9 f.lg/L. This
well has been outside the chloroform plume boundary since the fourth quarter of2010. In
the past, TW 4-6 has been both within and outside the plume. From the first quarter of
2009 through the fourth quarter of 2010, TW 4-6 was within the plume. Prior to that time,
between the time of installation in the second quarter of 2000 and the fourth quarter of
2008, TW 4-6 was outside the plume. Although fluctuations in concentrations have
occurred, this well likely remained outside the plume between installation in 2000 and the
fourth quarter of 2008 due to a combination of 1) slow rates of downgradient chloroform
migration in this area due to low permeability conditions and the effects of upgradient
chloroform removal by pumping, and 2) natural attenuation. The decreases in
concentrations at TW 4-6 since the fourth quarter of 2009 are likely the result of
upgradient pumping, in particular pumping at adjacent well TW4-4 (which commenced
in the first quarter of 2010). Chloroform remained non-detect at downgradient temporary
well TW4-23. TW4-23 and TW4-6 (with a chloroform concentration of 6.9 f.lg/L) bound
the chloroform plume to the south. TW4-8, TW4-12, TW4-13, TW4-14, and TW4-27
bound the chloroform plume to the east.
Continued pumping of MW-4, MW-26, TW4-19, and TW4-20 is recommended.
Pumping these wells, regardless of any short term fluctuations in concentrations detected
at the wells (such as at TW4-20), helps to reduce downgradient chloroform migration by
removing chloroform mass and reducing average hydraulic gradients, thereby allowing
natural attenuation to be more effective. Continued pumping at TW 4-4 is also
recommended to improve capture of chloroform to the extent practical in the southern
portion of the plume where low permeability conditions exist. The general decrease in
chloroform concentrations at TW4-6 from 1000 f.lg/L to 6.9 f.lg/L since the first quarter of
2010 is likely related to pumping at TW4-4. The decrease in the long-term rate of water
level rise at TW 4-6 since TW 4-4 pumping began, which suggests that TW 4-6 is within
24

the hydraulic influence of TW 4-4, IS consistent with the decrease In chloroform
concentrations at TW 4-6.

Sample Delivery Group: C12081321 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 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.

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.

Sample Delivery Group: C12090222 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (±2'C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

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.

REVISED/SUPPLEMENTAL REPORT (2)
Revised Date: 10/25/12
Report Date: 09/28/12
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
October 24, 2012 for the correction of the VOC's on sample -016. Due to the collection date change, the sample should
have been flagged with an H flag. The data presented here is from that correction.
REVISED/SUPPLEMENTAL REPORT (1)
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
September 28, 2012 to change the collection date on the Trip Blank to 9/10/12 and to add a collection date of 9/13/12 to
the Temp Blank.
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.

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.

RPD > 10%. Per the revised QAP Revision 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 tmbidity parameters are measured for information
purposes only and as such are not required to meet the 10% RPD criteria used for pH, specific conduc..:..::ta.:.:.:n:.:..ce=-a:.:.::.n:.::d....:.te.;,..m--!p!:..:e __ ra:.:.::.tur~e. ____ ----....--_---......-_------_-_~--_-----------,r-----------~--.
The QAP states that turbidity should be less than 5 Nephelometric Turbidity Units ('~NTU") prior to sampling unless the well is characterizeM b1 water that has a higher turbidity. The Ql\P does not require tnat turbiClittr measm;,ements be less than 5 NTU
