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"), Division of
Waste Management and Radiation Control ("DWMRC") 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 of UAC R317-6-6.15(D). In response to the NOV,
EFRI submitted a series of documents outlining plans for investigation of the chloroform
contamination. This plan of action and preliminary schedule was set out in EFRI submittals
dated: September 20, 1999; June 30, 2000; April 14, 2005; and November 29, 2006. EFRI
submitted a draft Groundwater Corrective Action Plan ("GCAP") dated August 22, 2007. The
draft GCAP was reviewed by the Director, who advised EFRI in 2013 that modifications were
required. In an effort to expedite and formalize active and continued remediation of the
chloroform plume, both parties have agreed to the GCAP found in Attachment 1, of the final
Stipulation and Consent Order ("SCO") dated September 14, 2015.
This is the Quarterly Chloroform Monitoring Report for the second quarter of 2018 as required
under the SCO. This report also includes the Operations Report for MW-04, TW4-01, TW4-04,
TW4-02, TW4-11, TW4-19, TW4-20, TW4-21 , MW-26, TW4-22, TW4-24, TW4-25, TW4-37,
TW4-39, and TW4-41 for the quarter.
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 Chloroform Monitoring
Quarterly sampling for chloroform monitoring parameters is currently required in the following
wells:
MW-4 TW4-9 TW4-18 TW4-27 TW4-36
TW4-1 TW4-10 TW4-19 TW4-28 TW4-37
TW4-2 TW4-l 1 TW4-20 TW4-29 TW4-38
TW4-3 TW4-12 TW4-21 TW4-30 TW4-39
TW4-4 TW4-13 TW4-22 TW4-31 TW4-40
TW4-5 TW4-14 TW4-23 TW4-32 TW4-41
TW4-6 MW-26 (formerly TW4-15) TW4-24 TW4-33
TW4-7 TW4-16 TW4-25 TW4-34
TW4-8 MW-32 (formerly TW4-17) TW4-26 TW4-35

Chloroform monitoring was performed in all of the required chloroform monitoring wells. 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) when 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.
2.1.2 Parameters Analyzed
Wells sampled during this reporting period were analyzed for the following constituents:
• Chloroform
• Chloromethane
• Carbon tetrachloride
• Methylene chloride
• 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 7.3, dated August 15, 2017.
2.1.3 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or 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 that 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.
Weekly and monthly depth to groundwater measurements were taken in the chloroform pumping
wells MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-37,
TW4-39, and TW4-41 and the nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-02.
In addition, monthly water level measurements were taken in non-pumping wells MW-27, MW-
30, MW-31, TW4-21, TWN-1, TWN-3, TWN-4, TWN-7, and TWN-18.

2.2 Sampling Methodology and Equipment and Decontamination Procedures
EFRI completed, and transmitted to DWMRC on May 25, 2006, a revised QAP for sampling
under the Mill's 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 DWMRC's approval of the QAP, for reasons set
out in correspondence to DWMRC dated December 8, 2006. Subsequent to the delivery of the
December 8, 2006 letter, EFRI discussed the issues brought forward in the letter with DWMRC
and has received correspondence from DWMRC about those issues. In response to DWMRC's
letter and subsequent discussions with DWMRC, EFRI modified the chloroform Quality
Assurance ("QA") procedures within the Chloroform QAP. The Chloroform QAP describes the
requirements of the chloroform investigation program and identifies 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 6, 2012 and August 15, 2017. The revised Groundwater QAP and
Chloroform QAP, Revision 7.3 were approved by DWMRC on August 29, 2017.
The sampling methodology, equipment and decontamination procedures used in the chloroform
contaminant investigation, as summarized below, are consistent with the approved QAP
Revision 7.3 and the Chloroform QAP.
2.2.1 Decontamination Procedures
Non-dedicated sampling equipment is decontaminated prior to use as described in the DWMRC-
approved QAP and as summarized below.
The water level meter is decontaminated with a detergent/deionized ("DI") water mixture by
pouring the solutions over the water level indicator. The water level meter is then rinsed with DI
water.
The field measurement instrument probe is decontaminated by rinsing with DI water prior to
each calibration. The sample collection cup is washed with a detergent/DI water solution and
rinsed with fresh DI water prior to each calibration.
The non-dedicated purging pump is decontaminated after each use and prior to use at subsequent
sampling locations using the following procedures:
a) the pump is submerged into a 55-gallon drum of nonphosphate detergent/DI water mixture;
b) the detergent/DI water solution is pumped through the pump and pump outlet lines into the
drain line connected to Cell 1;
c) the pump is submerged into a 55-gallon drum of DI water;
d) the DI water solution is pumped through the pump and pump outlet lines into the drain line
connected to Cell 1 ;

2.2.2 Well Purging and Depth to Groundwater
The non-pumping wells are purged prior to sampling by means of a portable pump. A list of the
wells in order of increasing chloroform concentration is generated quarterly. The order for
purging the non-pumping wells 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 wells with detectable chloroform concentrations staring with the lowest
concentration and proceeding to the wells with the highest concentration. One deviation to this
practice is made for the continuously pumping wells. These wells are sampled throughout the
sampling event and are not sampled in the order of contamination. This practice does not affect
the samples for this reason: the pumping wells have dedicated pumps and there will be no cross-
contamination resulting from the sampling order.
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. As noted in the approved QAP, Revision 7.3, sampling will
generally follow the same order as purging; however; 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 either have 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 the sampling order.
Before leaving the Mill office, the portable pump and hose are rinsed with DI water. Where
portable (non-dedicated) sampling equipment is used, a rinsate sample is 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 are used to remove stagnant water from the casing during
groundwater sampling at the Mill. The three strategies are as follows:
1. Purging three well casing volumes with a single measurement of field parameters
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% Relative Percent
Difference ["RPD"])
3. Purging a well to dryness and stability (within 10% RPD) 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 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
4
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. After sampling, the pump is turned off and allowed
to resume its timed schedule.
2.2.3 Sample Collection
Prior to sampling, 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 disposable 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 HCl;
• A sample for nitrate/nitrite is then collected. This sample consists of one 250 ml. bottle
that is provided by the Analytical Laboratory. The nitrate/nitrite sample is not filtered
and is preserved with H2S04;
• A sample for chloride is then collected. This sample consists of one 500 ml. bottle that is
provided by the Analytical Laboratory. The chloride sample is 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.
2.3 Field Data
Attached under Tab B are copies of the Field Data Worksheets that were completed during the
quarter for the chloroform contaminant investigation monitoring wells identified in paragraph
2.1.1 above, and Table 1.

2.4 Depth to Groundwater Data and Water Table Contour Map
Attached under Tab C are copies of the Depth to Water Sheets for the weekly monitoring of
MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22, TW4-
24, TW4-25, TW4-37, and TWN-2 as well as the monthly depth to groundwater data for the
chloroform contaminant investigation wells and the non-pumped wells measured during the
quarter. Depth to groundwater measurements that were utilized for groundwater contours are
included on the Quarterly Depth to Water Worksheet at Tab D of this report, along with the
kriged groundwater contour map for the current quarter generated from this data. A copy of the
kriged groundwater contour map generated from the previous quarter's data is provided under
Tab E.
2.5 Laboratory Results
2.5.1 Copy of Laboratory Results
All analytical results were provided by American West Analytical Laboratory ("AW AL"). Table
I lists the dates when analytical results were reported to the QA Manager for each sample.
Results from the analyses of samples collected for this quarter's chloroform contaminant
investigation are provided under Tab H of this Report. Also included under Tab H are the results
of the 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 SCO triggered a series of actions on EFRI's part. In
addition to the monitoring program, EFRI has equipped one nitrate well and fourteen chloroform
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 QAfQuality 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 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 QNQC are discussed in Sections 3.4.4 through 3.4.9 below.
6
The analytical laboratory has provided summary reports of the analytical QA/QC measurements
necessary to maintain conformance with National Environmental Laboratory Accreditation
Conference ("NELAC") certification and reporting protocol. The Analytical Laboratory QA/QC
Summary Reports, including copies of the Mill's Chain of Custody and Analytical Request
Record forms for each set of Analytical Results, follow the analytical results under Tab H.
Results of the review of the laboratory QA/QC 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 that contains VOCs, one DIFB and
rinsate samples.
During this quarter, three 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 AW AL and returned with the quarterly chloroform
monitoring samples.
Two rinsate blank samples were collected 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. TW4-7R).
The results of these analyses are included with the routine analyses under Tab H.
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
The QA Manager's review of Mill Personnel's adherence to the existing SOPs, confirmed that
the QA/QC requirements established in the QAP and Chloroform QAP were met.
3.3 Analyte Completeness Review
All analyses required by the GCAP 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 QA/QC evaluation, a holding time check, a receipt
temperature check, an analytical method check, a reporting limit evaluation, a trip blank check, a
7
QA/QC 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 QA/QC Evaluation
The QA Manager performs a review of the 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 the
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 of
field data are provided under Tab I.
Based upon the review of the field data sheets, the purging and field measurements were
completed in conformance with the QAP 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 TW4-5, TW4-8, TW4-9, TW4-16, MW-32, TW4-18, TW4-23, TW4-32, TW4-38, and
TW 4-40 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 TW4-3, TW4-6, TW4-7, TW4-10, TW4-12, TW4-13, TW4-14, TW4-26, TW4-27, TW4-
28, TW4-29, TW4-30, TW4-31, TW4-33, TW4-34, TW4-35, and TW4-36 were pumped to
dryness before two casing volumes were evacuated. After well recovery, one set of
measurements of pH, conductivity and temperature were taken. The samples were then collected,
and another set of measurements of pH, conductivity and temperature were taken. Stabilization
of pH, conductivity and temperature are required within 10% RPD under the QAP, Revision 7.3.
The QAP requirements for stabilization were met.
Continuously Pumped Wells
Wells MW-4, TW4-1, TW4-2, TW4-4, TW4-11, MW-26, TW4-19, TW4-20, TW4-21, TW4-22,
TW4-24, TW4-25, TW4-37, TW4-39, and TW4-41 are continuously pumped wells. These wells
are pumped on a set schedule per the remediation plan and are considered sufficiently evacuated
to immediately collect a sample.
During review of the field data sheets, the QA Manager confirmed that sampling personnel
consistently recorded depth to water to the nearest 0.01 foot.
The review of the field sheets for compliance with QAP, Revision 7.3 requirements resulted in
the observations noted below. The QAP requirements in Attachment 2-3 specifically state that
8
field parameters must be stabilized to within 10% over at least 2 consecutive measurements for
wells purged to 2 casing volumes or purged to dryness. 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 below
regarding turbidity measurements greater than 5 NTU are included for information purposes
only.
Wells TW4-9, TW4-11, TW4-16, MW-32, TW4-18, TW4-20, TW4-21, TW4-23, TW4-32,
TW4-38, TW4-40, and TW4-41 exceeded the QAP's 5 NTU goal. EFRI's letter to DWMRC of
March 26, 2010 discusses further why turbidity does not appear to be an appropriate parameter
for assessing well stabilization. In response to DWMRC's subsequent correspondence dated
June 1, 2010 and June 24, 2010, EFRI completed a monitoring well redevelopment program.
The redevelopment report was submitted to DWMRC on September 30, 2011. DWMRC
responded to the redevelopment rep01t via letter on November 15, 2012. Per the DWMRC 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 samples were received and analyzed within the required
holding times.
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. The samples were received within the required temperature limit.
3.4.4 Analytical Method Checklist
The 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. The
analytical methods were consistent with the requirements of the Chloroform QAP.
3.4.5 Reporting Limit Evaluation
The 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. The analytes were measured and reported to the required reporting limits; several
sets of sample results had the reporting limit raised for at least one analyte due to matrix
interference and/or sample dilution. In these 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 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 the volatile
samples were received at the laboratory with a pH less than 2.
3.4.7 Trip Blank Evaluation
Trip blank results were reviewed to identify any VOC contamination resulting from transport of
the samples. Trip blank checks are provided in Tab I. The trip blank results were less than the
reporting limit for all voes.
3.4.8 QA/QC 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 the duplicate pairs for all analytes
regardless of whether or not the reported concentrations are greater than 5 times the required
detection limits; however, data are 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.
Duplicate results were within a 20% RPD in the quarterly samples. Duplicate results are included
in Tab I.
3.4.9 Rinsate Sample Check
Rinsate blank sample checks are provided in Tab I. The rinsate blank sample concentration
levels were compared to the QAP requirements i.e., that rinsate sample concentrations be one
order of magnitude lower than that of the actual well. The rinsate blank sample results were
nondetect for this quarter.
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 results were nondetect.
3.4.10 Other Laboratory QA/QC
Section 9.2 of the QAP requires that the laboratory's QA/QC Manager check the following items
in developing data reports: (1) sample preparation information is 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
10
(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.
The lab QA/QC 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 QA/QC Summary Reports indicates that the MS/MSDs
recoveries and the associated RPDs for the samples were within acceptable laboratory limits for
the regulated compounds except as noted in Attachment I. The data recoveries which are outside
the laboratory established acceptance limits do not affect the quality or usability of the data
because the recoveries outside of the acceptance limits are indicative of matrix interference.
Matrix interferences are applicable to the individual sample results only. The requirement in the
QAP 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 QA/QC Summary Reports indicates that the surrogate recoveries for the
quarterly chloroform samples were within acceptable laboratory limits for the surrogate
compounds. The requirement in the QAP to analyze surrogate compounds was met and the data
are compliant with the QAP. Furthermore, there are no QAP requirements for surrogate
recoveries.
The QAP, Section 8.1.2 requires that each analytical batch shall be accompanied by a method
blank. The analytical batches routinely contain a blank, which is a blank sample made and
carried through all analytical steps. For the Mill samples, a method blank was prepared for the
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 states that non-conformance conditions will exist when contaminant levels in the
samples(s) are not an order of magnitude greater than the blank result. The method blanks for
the quaiterly samples had reported detections above the RL of chloromethane. The method
blanks reported detection while the associated samples were all nondetect for chloromethane.
The samples are not an order of magnitude greater than the blank as required by the QAP, but
there is no effect on the usability of the data because the samples reported no detections. This
11
indicates that the contamination which affected the method blank did not affect the samples and
no false positive results were reported in the samples as a result of the contamination.
Method blank results are included in Tab H.
The information from the Laboratory QNQC Summary Reports indicates that the LCS
recoveries for the samples were within acceptable laboratory limits for the regulated compounds
as indicated in Tab I.
4.0 INTERPRETATION OF DATA
4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions.
4.1.1 Current Site Groundwater Contour Map
The water level contour maps (See Tab D) 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 south of the tailings cells.
Perched water mounding associated with the wildlife ponds locally changes the generally
southerly perched water flow patterns. For example, northeast of the Mill site, mounding
associated with formerly used wildlife ponds is still evident and disrupts the generally
southwesterly flow pattern, to the extent that locally northerly flow occurs near MW-19 and
PIEZ-1. The impact of the mounding associated with the northern ponds, to which water has not
been delivered since March 2012, is diminishing and is expected to continue to diminish as the
associated mound decays due to reduced recharge. The perched groundwater mound associated
with the southern wildlife pond is also diminishing due to reduced recharge at that location.
Not only has recharge from the wildlife ponds impacted perched water elevations and flow
directions at the site, but the cessation of water delivery to the northern ponds, which are
generally upgradient of the nitrate and chloroform plumes at the site, resulted in changing
conditions that were expected to impact constituent concentrations and migration rates within the
plumes. Specifically, past recharge from the northern ponds helped limit many constituent
concentrations within the plumes by dilution while the associated groundwater mounding
increased hydraulic gradients and contributed to plume migration. Since use of the northern
ponds was discontinued in March 2012, increases in constituent concentrations in many wells,
and decreases in hydraulic gradients within the plumes, are attributable to reduced recharge and
the decay of the associated groundwater mound. EFRI and its consultants anticipated these
changes and discussed these and other potential effects with DWMRC in March 2012 and May
2013.
The impacts associated with cessation of water delivery to the northern ponds were expected to
propagate downgradient (south and southwest) over time. Wells close to the ponds were
generally expected to be impacted sooner than wells farther downgradient of the ponds.
Therefore, constituent concentrations were generally expected to increase in downgradient wells
close to the ponds before increases were detected in wells farther downgradient of the ponds.
Although such increases were anticipated to result from reduced dilution, the magnitude and
12
timing of the increases were anticipated to be and have been difficult to predict due to the
complex permeability distribution at the site and factors such as pumping and the rate of decay of
the groundwater mound. Because of these complicating factors, some wells completed in higher
permeability materials were expected to be impacted sooner than other wells completed in lower
permeability materials even though the wells completed in lower permeability materials were
closer to the ponds.
In general, chloroform and nitrate concentrations within and in the vicinity of the chloroform
plume appear to have been impacted to a greater extent than nitrate concentrations within and
adjacent to the nitrate plume. This behavior is reasonable considering that the chloroform plume
is generally more directly downgradient of and more hydraulically connected (via higher
permeability materials) to the northern wildlife ponds.
In addition, the southern wildlife pond is in relatively close proximity to the downgradient
(southern) extremity of the chloroform plume. Reduced recharge at the southern pond, and decay
of the associated groundwater mound, can be expected to impact water level behavior and
chloroform and nitrate concentrations in wells within this portion of the chloroform plume.
Localized increases in concentrations of constituents such as chloroform and nitrate within and
near the chloroform plume, and of nitrate and chloride within and near the nitrate plume, may
occur even when these plumes are under control. Ongoing mechanisms that can be expected to
increase constituent concentrations locally as a result of reduced wildlife pond recharge include
but are not limited to:
1) Reduced dilution -the mixing of low constituent concentration pond recharge into
existing perched groundwater will be reduced over time.
2) Reduced saturated thicknesses -dewatering of higher permeability layers rece1vmg
primarily low constituent concentration pond water will result in wells intercepting these
layers receiving a smaller proportion of the low constituent concentration water.
The combined impact of the above two mechanisms was anticipated to be more evident at
chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20; nitrate pumping
wells TW4-22, TW4-24, TW4-25, and TWN-2; and non-pumped wells adjacent to the pumped
wells. Impacts were also expected to occur over time at wells added to the chloroform pumping
network during the first quarter of 2015 (TW4-1, TW4-2, TW4-11); at those added during the
second quarter of 2015 (TW4-21 and TW4-37); at TW4-39, added during the fourth quarter of
2016; and at new well TW4-41, added this quarter. The overall impact was expected to be
generally higher constituent concentrations in these wells over time until mass reduction
resulting from pumping and natural attenuation eventually reduces concentrations. Short-term
changes in concentrations at pumping wells and wells adjacent to pumping wells are also
expected to result from changes in pumping conditions.
In addition to changes in the flow regime caused by wildlife pond recharge, perched flow
directions are locally influenced by operation of the chloroform and nitrate pumping wells. Well
defined cones of depression are typically evident in the vicinity of all chloroform pumping wells
13
except TW4-4 and TW4-37, which began pumping in the first quarter of 2010 and the second
quarter of 2015, respectively.
The lack of well-defined capture associated with chloroform pumping well TW4-4 has been
consistent, even though pumping since the first quarter of 2010 has depressed the water table in
the vicinity of this well. The lack of a well-defined cone of depression near TW4-4 likely results
from 1) variable permeability conditions in the vicinity of TW4-4, and 2) persistent relatively
low water levels at adjacent well TW 4-14.
Nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 started pumping during the first
quarter of 2013. Water level patterns near these wells are expected to be influenced by the
presence of, and the decay of, the groundwater mound associated with the northern wildlife
ponds, and by the persistently low water level elevation at TWN-7. By the fourth quarter of
2013, operation of the nitrate pumping system had produced well-defined impacts on water
levels. The long-term interaction between the nitrate and chloroform pumping systems is
evolving, and changes will be reflected in data collected during routine monitoring.
As discussed above, variable permeability conditions likely contribute to the lack of a well-
defined cone of depression near chloroform pumping well TW 4-4. Changes in water levels at
wells immediately south and southeast (downgradient) of TW4-4 resulting from TW4-4 pumping
are expected to be muted because TW 4-4 is located at a transition from relatively high to
relatively low permeability conditions south and southeast of TW4-4. As will be discussed
below, the permeability of the perched zone at TW4-6, TW4-26, TW4-29, TW4-30, TW4-31,
TW4-33, TW4-34, and TW4-35 is one to two orders of magnitude lower than at TW4-4, and the
permeability at TW4-27 is approximately three orders of magnitude lower than at TW4-4.
Detecting water level drawdowns in wells immediately south and southeast of TW 4-4 resulting
from TW4-4 pumping has also been complicated by a general, long-term increase in water levels
that occurred in this area that is attributable to past wildlife pond recharge. Between the fourth
quarter of 2007 and the fourth quarter of 2009 Uust prior to the start of TW 4-4 pumping), water
levels at TW4-4 and TW4-6 increased by nearly 2.7 and 2.9 feet at rates of approximately 1.2
feet/year and 1.3 feet/year, respectively. However, between the start of pumping at TW4-4 (first
quarter of 2010) and the fourth quarter of 2013, the rate of increase in water levels at TW4-6 was
reduced to less than 0.5 feet/year suggesting that TW 4-6 is within the hydraulic influence of
TW4-4.
Since the fourth quarter of 2013, water levels in all wells currently within the chloroform plume
south of TW4-4 (TW4-6, TW4-29, and TW4-33) have been trending generally downward. This
downward trend is attributable to both the cessation of water delivery to the wildlife ponds and
pumping. Generally increasing water levels, except for an apparent stabilization during 2016, are
now confined to some of the wells marginal to the chloroform plume such as TW4-14, TW4-27,
TW4-30, and TW4-31.
These spatially variable water level trends likely result from pumpmg conditions, the
permeability distribution, and distance from the wildlife ponds. Wells that are relatively
hydraulically isolated (due to completion in lower permeability materials or due to intervening
14
lower permeability materials) and that are more distant from pumping wells and the wildlife
ponds, are expected to respond more slowly to pumping and reduced recharge than wells that are
less hydraulically isolated and are closer to pumping wells and the wildlife ponds. Wells that are
more hydraulically isolated will also respond more slowly to changes in pumping.
The continuing lack of a well-defined cone of depression at TW4-4 has also been influenced by
the persistent, relatively low water level at non-pumping well TW4-14, located east of TW4-4
and TW4-6. Although water level differences among these three wells have been diminishing,
the water level at TW4-14 has typically been lower than the water level at TW4-6 and has been
several feet lower than the water level at TW 4-4 even though TW 4-4 has been pumping since
2010. For the current quarter, however, the water level at TW4-14 (approximately 5534.7 feet
above mean sea level ["ft amsl"]), is less than 1 foot higher than the water level at TW4-6
(approximately 5533.9 ft amsl) and is nearly 3 feet higher than the water level at TW4-4
(approximately 5531.8 ft amsl). This change is attributable to operation of new chloroform
pumping well TW4-41, located immediately northeast of TW4-4. The combined pumping of
TW 4-4 and TW 4-41 is expected to enhance capture in this area.
The static water levels at wells TW4-14 and downgradient well TW4-27 (installed south of
TW4-14 in the fourth quarter of 2011) were similar (within 1 to 2 feet) until the third quarter of
2014; both appeared anomalously low. 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
(respectively) of TW4-4 and TW4-6. 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 TW4-4 and TW4-6 (respectively); however chloroform exceeding 70 µg/L
has been detected at more recently installed temporary perched wells TW4-29 (located south of
TW4-27) and TW4-33 (located between TW4-4 and TW4-29).
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 had not been detected at TW4-14. Chloroform had apparently migrated from
TW4-4 to TW4-6 and from TW4-6 to TW4-26. This suggested that TW4-26 was actually
downgradient of TW4-6, and TW4-6 was actually downgradient of TW4-4, regardless of the
flow direction implied by the low water level at TW4-I4. The water level at TW4-26 (5532.7
feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5533.9 feet amsl), and
TW4-23 (5535.3 feet amsl), as shown in the detail water level map under Tab C.
Hydraulic tests indicate that the permeability at TW4-27 is an order of magnitude lower than at
TW4-6 and three orders of magnitude lower than at TW4-4 (see Hydro Geo Chem, Inc. [HGC],
September 20, 2010: Hydraulic Testing of TW4-4, TW4-6, and TW4-26, White Mesa Uranium
Mill, July 2010; and HGC, November 28, 2011: Installation, Hydraulic Testing, and Perched
Zone Hydrogeology of Perched Monitoring Well TW4-27, White Mesa Uranium Mill Near
Blanding, Utah). Past similarity of water levels at TW4-I4 and TW4-27, and the low
permeability estimate at TW4-27, suggested that both wells were completed in materials having
lower permeability than nearby wells. The low permeability condition likely reduced the rate of
long-term water level increase at TW4-14 and TW4-27 compared to nearby wells, yielding water
levels that appeared anomalously low. This behavior is consistent with hydraulic test data
collected from more recently installed wells TW4-29, TW4-30, TW4-31, TW4-33, TW4-34 and
15
TW4-35, which indicate that the permeability of these wells is one to two orders of magnitude
higher than the permeability of TW4-27 (see: HGC, January 23, 2014, Contamination
Investigation Report, TW4-12 and TW4-27 Areas, White Mesa Uranium Mill Near Blanding,
Utah; and HGC, July 1, 2014, Installation and Hydraulic Testing of TW4-35 and TW4-36,
White Mesa Uranium Mill Near Blanding, Utah [As-Built Report]). Hydraulic tests also indicate
that the permeability at TW4-36 is slightly higher than but comparable to the low permeability at
TW4-27, suggesting that TW4-36, TW4-14 and TW4-27 are completed in a continuous low
permeability zone.
The current quarterly water level at TW4-27 (approximately 5529.1 ft. amsl) is more than 5 feet
lower than the water level at TW4-14 (5534.7 ft. amsl). Increases in water level differences
between TW4-14 and TW4-27 since 2013 are attributable to more rapid increases in water levels
at TW4-14 compared to TW4-27. This behavior likely results primarily from: the relative
positions of the wells; past water delivery to the northern wildlife ponds; and the permeability
distribution. Past seepage from the ponds caused propagation of water level increases in all
directions including downgradient to the south. The relative hydraulic isolation of TW4-14 and
TW4-27 delayed responses at these locations to such an extent that they are still responding to
the past seepage. Water levels at these wells are still lower than in surrounding higher
permeability materials even though water levels in surrounding materials are now generally
decreasing due to reduced pond seepage and pumping. As a result, water levels at TW4-14 and
TW4-27 are still increasing. Compared to TW4-27, the rate of increase is higher at TW4-14 due
to factors that include: closer proximity to the northern pond seepage source; a smaller thickness
of low permeability materials separating TW 4-14 from surrounding higher permeability
materials; and hydraulic gradients between TW 4-14 and surrounding higher permeability
materials that on average have been larger. Slowing of the rates of water level increase at TW 4-
14 (since 2015) and TW4-27 (since early 2014) is attributable to reduced hydraulic gradients as
TW4-14 and TW4-27 water levels 'catch up' with water levels in surrounding higher
permeability materials.
In addition, water levels in this area may also be affected by reduced recharge at the southern
wildlife pond and the consequent decay of the associated groundwater mound. The decay of the
mound is likely to contribute to the reduction in hydraulic gradients between the low
permeability materials penetrated by TW4-14 and TW4-27 and the surrounding higher
permeability materials. TW4-27 is closer to the southern wildlife pond than TW4-14. Any
reduction in hydraulic gradients attributable to the southern pond is expected to impact TW4-27
sooner and to a greater extent than TW 4-14, consistent with the lower rate of increase in water
levels at TW4-27, and the earlier reduction in the rate of increase (since early 2014) as discussed
above).
The low permeability at TW4-14 and TW4-27 is expected to retard the transport of chloroform
to these wells (compared to nearby wells). As will be discussed in Section 4.2.3, TW4-14 and
TW 4-27 remain outside the plume with current quarter chloroform concentrations of
approximately 5.12 µg/L and 5.95 µg/L, respectively.
Chloroform exceeding 70 µg/L detected at TW4-29 and TW4-33 since their installation in 2013
indicates that, in addition to migrating south from TW4-4 to TW4-6 and TW4-26, chloroform
16
also migrated along a narrow path to the southeast from the vicinity of TW 4-4 to TW 4-33 then
TW4-29. Such migration was in a direction nearly cross-gradient with respect to the direction of
groundwater flow implied by the historic groundwater elevations in this area, which, until
relatively recently, placed TW4-14 almost directly downgradient of TW4-4. Such migration was
historically possible because the water levels at TW4-29 have been lower than the water levels at
TW4-4 (and TW4-6). The permeability and historic water level distributions are generally
consistent with the apparent nearly cross-gradient migration of chloroform from TW4-4 around
the low permeability zone defined by TW4-36, TW4-14, and TW4-27.
Chloroform during the current quarter was detected at approximately 16.9 µg/L at TW4-30
(located east and downgradient of TW4-29), and was not detected at wells TW4-31 (located east
of TW4-27), TW4-34 (located south and cross-gradient of TW4-29), nor TW4-35 (located
southeast and generally cross-to downgradient of TW 4-29).
Data from wells within and adjacent to the southern portion of the chloroform plume indicate
that:
1. Chloroform exceeding 70 µg/L at TW4-29 is bounded by concentrations below 70 µg/L at
wells TW4-23, TW4-27, TW4-30, TW4-34, and TW4-35. TW4-30 is downgradient of
TW4-29; TW4-23 is generally cross-to upgradient of TW4-29; and TW4-27, TW4-34
and TW 4-35 are generally cross-to down gradient of TW 4-29.
2. Chloroform concentrations at TW4-33 that are lower than concentrations at TW4-29, and
the likelihood that a pathway exists from TW4-4 to TW4-33 to TW4-29, suggest that
concentrations in the vicinity of TW4-33 were likely higher prior to initiation of TW4-4
pumping, and that lower concentrations currently detected at TW4-33 are due to its closer
proximity to TW 4-4.
3. Chloroform concentrations at TW4-26 exceeded 70 µg/L for the first time during the
second quarter of 2017. Chloroform at TW4-26 is bounded by non-detectable
concentrations at TW4-23 (located up-to cross-gradient of TW4-26), and at TW4-34
(located downgradient of TW4-26). Chloroform at TW4-26 is bounded far to the south-
southwest ( cross-gradient) by MW-17 (non-detect) and far to the south ( cross-to
downgradient) by MW-22 (non-detect) but is not bounded directly to the south by any
nearby wells. New chloroform well TW 4-40 was installed approximately 200 feet south
of TW4-26 in February, 2018. Chloroform at TW4-40 during the initial and current
quarter's sampling exceeded 70 µg/L.
Eventually, TW4-4 pumping, enhanced by operation of adjacent new pumping well TW4-41, is
likely to reduce chloroform at both TW4-33 and TW4-29 by cutting off the source. The decrease
at TW4-33 is expected to be faster than at TW4-29 because TW4-33 is in closer proximity to
TW 4-4 pumping. Such behavior is expected by analogy with the temporary decreases in
chloroform concentrations that occurred at TW4-6 and TW4-26 once TW4-4 pumping began
(discussed in Section 4.2.3). Since installation in 2013, however, concentrations at TW4-33
appear to be relatively stable; since the third quarter of 2014, concentrations at TW4-29 appear to
be generally increasing.
17
Relatively stable chloroform at TW4-33 and generally increasing concentrations at TW4-29
suggest that chloroform migration has been arrested at TW4-33 by TW4-4 pumping and that
increasing chloroform at downgradient well TW4-29 results from a remnant of the plume that
continues to migrate downgradient (toward TW4-30, which bounds the plume to the east). The
influence of TW4-4 pumping at the distal end of the plume is consistent with generally
decreasing water levels at both TW4-29 and TW4-33.
However, decreasing water level trends are also consistent with reduced wildlife pond seepage.
The decay of the groundwater mound associated with the southern wildlife pond, which is 3 to 4
times closer to the southern extremity of the chloroform plume than the northern ponds, is likely
to have an impact on water levels within and adjacent to this portion of the plume.
At TW4-6 and TW4-26, decreasing water level trends (since about the fourth quarter of 2013),
and increased concentrations (since the first quarter of 2014 and the third quarter of 2016,
respectively) are also consistent with reduced wildlife pond seepage, in particular, reduced
seepage from the southern wildlife pond. As the groundwater mound associated with the
southern pond decays, groundwater flow directions in the southern extremity of the plume are
likely to become more southerly, and plume migration is likely to turn more to the south. An
increasingly southerly direction of plume migration is consistent with increasing concentrations
at TW4-26.
In addition, generally decreasing concentrations at TW4-6 since the third quarter of 2015, and
generally increasing concentrations at TW4-26 since the third quarter of 2016, suggest that TW4-
4 pumping has arrested chloroform migration between TW 4-4 and TW 4-6, and that increasing
chloroform at TW4-26 results from a remnant of the plume that continues to migrate south from
TW4-6 to TW4-26.
Detectable chloroform concentrations at TW4-14 (since the fourth quarter of 2014) and TW4-27
(since the third quarter of 2015) suggest ongoing, but slow, downgradient migration of
chloroform from the distal end of the plume (defined by TW4-29 and TW4-33) into the low
permeability materials penetrated by TW4-14 and TW4-27.
4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater Contour
Maps for Previous Quarter
The groundwater contour map for the Mill site for the first quarter of 2018, as submitted with the
Chloroform Monitoring Report for the first quarter of 2018, is attached under Tab E. A
comparison of the water table contour maps for the current quarter (second quarter of 2018) to
the water table contour maps for the previous quarter (first quarter of 2018) indicates the
following: water level changes at the majority of site wells were small ( < lfoot); water level
contours have not changed significantly except for a few locations (most notably chloroform
pumping well TW4-39 and nitrate pumping well TW4-25). Increases in drawdown at chloroform
pumping well TW4-39 and new pumping well TW4-41 compensated for reduced drawdown and
apparent capture at nitrate pumping wells TW4-25 and TWN-2, resulting in an overall area of
apparent capture that is similar to last quarter.

Drawdown patterns and overall capture associated with pumping of the original chloroform
pumping wells MW-4, MW-26, and TW4-19 have changed as additional groups of wells have
been added to the pumping network. A large expansion in capture occurred within a year of the
initiation of pumping at nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 in the
first quarter of 2013. Another large expansion occurred once chloroform pumping wells TW4-1,
TW4-2, TW4-J 1, TW4-21 and TW4-37 became operational in 2015.
The drawdowns at chloroform pumping wells TW4-1, TW4-4, TW4-39 and new well TW4-41
increased by more than 2 feet this quarter; however drawdowns at chloroform pumping wells
MW-4, MW-26 and TW4-2, and nitrate pumping wells TW4-25 and TWN-2, decreased by more
than 2 feet this quarter. Water level changes at other nitrate and chloroform pumping wells were
2 feet or less, although both increases (decreases in drawdown) and decreases (increases in
drawdown) occurred. Water level fluctuations at pumping wells typically occur in part because
of fluctuations in pumping conditions just prior to and at the time the measurements are taken.
The reported water level for chloroform pumping well TW4-11 is below the depth of the Brushy
Basin contact this quarter. Although both increases and decreases in drawdown occurred in
pumping wells, the overall apparent capture area of the combined pumping system is similar to
last quarter.
As discussed in Section 4.1.1, pumping at chloroform well TW 4-4, 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 clearly evident, likely due to variable permeability conditions near TW4-4 and the
persistently low water level at adjacent well TW4-14. However, increased drawdown at TW4-4
related to pumping at adjacent new well TW4-41 has generally increased drawdowns in this area
and has contributed to southerly expansion of total pumping system capture this quarter.
Reported water level decreases of up to 0.31 feet at Piezometers 1 through 3A may result from
cessation of water delivery to the northern wildlife ponds as discussed in Section 4.1.1 and the
consequent continuing decay of the associated perched water mound. Reported water level
decreases of up to 0.36 feet at Piezometers 4 and 5 likely result primarily from reduced recharge
at the southern wildlife pond. Reported water level decreases of approximately 0.24 and 0.29feet,
respectively, at TWN-1 and TWN-4 are consistent with continuing decay of the northern
groundwater mound.
The reported water level at TW4-9 decreased by approximately 3.3 feet, likely the result of
increased drawdown at nearby pumping well TW4-39.
The reported water level at MW-20 decreased by approximately 3.5 feet. Water level variability
at MW-20 likely results from low permeability and variable intervals between purging/sampling
and water level measurement.
Measurable water was not reported at DR-22. Although DR-22 is typically dry, measurable
water was reported in the bottom of its casing between the second quarter of 2015 and the third
quarter of 2016.

4.1.5 Evaluation of the Effectiveness of Hydraulic Capture
Perched water containing chloroform has been removed from the subsurface by operating
chloroform pumping wells MW-4, MW-26 and TW4-19 since 2003; TW4-20 since 2005; TW4-
4 since 2010; TW4-1, TW4-2, TW4-11, TW4-21 and TW4-37 since 2015, and TW4-39 since the
fourth quarter of 2016. The primary purpose of the pumping is to reduce total chloroform mass
in the perched zone as rapidly as is practical. Pumping wells upgradient of TW4-4 were chosen
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 for a high rate of chloroform mass
removal. TW4-4 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 TW4-4. As with the other chloroform
pumping wells, pumping TW 4-4 helps to reduce the rate of chloroform migration in
downgradient portions of the plume.
The impact of chloroform pumping is indicated by the water level contour maps attached under
Tabs D and E. Cones of depression are evident in the vicinity of MW-4, MW-26, TW4-19, and
TW4-20 which continue to remove significant quantities of chloroform from the perched zone.
Relatively large cones of depression have developed in the vicinities of wells TW4-1, TW4-2,
and TW4-11 which began pumping during the first quarter of 2015. Overall, the water level
contour maps indicate effective capture of water containing high chloroform concentrations in
the vicinities of the pumping wells. As discussed in Section 4.1.1, although chloroform pumping
well TW4-4 became operational in 2010, the drawdown associated with TW4-4 is likely less
apparent due to variable permeability conditions near TW4-4 and the persistently low water level
at adjacent well TW4-14. However, increased drawdown at TW4-4 related to pumping at
adjacent new well TW4-41 has generally increased drawdowns in this area and has contributed
to southerly expansion of total pumping system capture this quarter.
Compared to last quarter, both increases and decreases in water levels occurred at nitrate and
chloroform pumping wells, although water levels in chloroform pumping wells TW4-11, -21, -37
and nitrate pumping well TW4-24, were approximately the same as last quarter. The water levels
in chloroform pumping wells MW-4, MW-26, TW4-2 and TW4-19 increased by approximately
4.9, 9.4, 14.7 and 0.8 feet, respectively; and the water levels in nitrate pumping wells TW4-22,
TW4-25 and TWN-2 increased by approximately 0.12, 31.6 and 11.8 feet, respectively. Water
20
level decreases of approximately 10.4, 8.7, 0.2, 35.6 and 13.1 feet occurred in chloroform
pumping wells TW4-1, TW4-4, TW4-20, TW4-39 and TW4-41. The apparent combined capture
area of the nitrate and chloroform pumping systems is approximately the same as last quarter,
although the area of the northern portion of the capture system has decreased and the southern
portion has expanded relative to last quaiter.
The capture associated with nitrate pumping wells and chloroform pumping wells added in 2015,
2016 and 2018 is expected to increase over time as water levels continue to decline due to
cessation of water delivery to the northern wildlife ponds and continued pumping. Slow
development of hydraulic capture in the vicinities of many wells is consistent with and expected
based on the relatively low permeability of the perched zone at the site.
The hydraulic capture effectiveness of both chloroform and nitrate pumping systems depends to
some extent on the continued productivity of chloroform and nitrate pumping wells. Decreases in
productivity have been noted since the third quarter of 2014 in chloroform pumping well TW4-
19 and nitrate pumping well TW4-24. The impact of reduced productivity of these wells on
chloroform capture was discussed in Attachment N (Tab N) of the third quarter, 2015 report. The
report also included a discussion of the effectiveness of chloroform pumping on chloroform
capture. 'Background' flow through the chloroform plume was calculated in Attachment N as
approximately 3.3 gpm. A more refined 'background' flow calculation of 3.4 gpm was provided
in the CACME Report (See HGC, March 31, 2016: Corrective Action Comprehensive
Monitoring Evaluation Report, White Mesa Uranium Mill, Near Blanding, Utah).
Decreases in productivity at TW4-4 since the third quarter of 2016 are being addressed by the
operation of new pumping well TW4-41 which is located adjacent to TW4-4.
Pumping from wells within and immediately adjacent to the chloroform plume during the current
quarter (from wells MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20,
TW4-21, TW4-22, TW4-24, TW4-37, TW4-39 and TW4-41) is approximately 5.3 gpm. This
calculation is based on the total volume pumped by these wells over the 90 day quarter (685,276
gallons) and accounts for times that the pumps are off due to insufficient water columns in the
wells. Pumping from these wells exceeds the calculated background flow by 1.9 gpm or 56%,
and is considered adequate at the present time even with the reduced productivities of some
wells. Reduced productivity is expected to be offset during future quarters by pumping at new
chloroform well TW 4-41. In addition, because of continued reductions in saturated thicknesses
and hydraulic gradients resulting from reduced wildlife pond recharge, 'background' flow
through the plume is expected to continue to diminish, thereby reducing the pumping needed to
control the plume.
Chloroform concentrations at many locations have been or appear to be affected by changes
associated with reduced dilution from the wildlife ponds and nitrate pumping. For example,
increases in chloroform at TW4-22 and TW4-24 after these wells were converted to nitrate
pumping wells are attributable to westward migration of chloroform from the vicinity of TW4-20
toward these wells. The increase in concentration at TW4-8 from non-detect to 100 µg/L in the
first quarter of 2014 (and to 155 µg/L this quarter) is likely related to reduced dilution. Although
the chloroform concentration in TW4-6 has decreased from 1,180 µg/L during the first quarter of
21
2015 to 74.9 µg/L this quarter, concentrations at TW4-6 have increased from approximately 10
µg/L since the second quarter of 2014. These changes are likely related to both reduced dilution
and more westward flow induced by nitrate pumping.
TW4-6 is located immediately south and cross-to downgradient of chloroform pumping well
TW4-4. Chloroform concentrations at TW4-6 exceeded 70 µg/L between the first quarter of
2009 and the third quarter of 2010, and remained below 70 µg/L between the fourth quarter of
2010 and the second quarter of 2014. Relatively low permeability and relatively small saturated
thickness in the vicinity of TW 4-6 limit the rate at which chloroform mass can be removed by
pumping. However, pumping at more productive upgradient locations such as TW4-4 enhances
mass removal and lowers hydraulic gradients, thereby reducing the rate of downgradient
chloroform migration and allowing natural attenuation to be more effective. Pumping at TW4-4
was implemented during the first quarter of 2010 to improve capture downgradient of TW 4-4 to
the extent allowable by the lower productivity conditions present in this area. The beneficial
effect of pumping TW 4-4 is demonstrated by the net decreases in TW 4-6 chloroform
concentrations from 1,000 µg/L to 10.3 µg/L, and in TW4-26 from 13 µg/L to 4.2 µg/L, between
the initiation of TW 4-4 pumping and the second quarter of 2014. Concentrations at these wells
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 TW4-6 after TW4-4 began pumping does suggest that TW4-6 is
within the hydraulic influence of TW4-4. The decline in water levels at TW4-6 since the fourth
quarter of 2013 likely reflects the additional influences of cessation of water delivery to the
wildlife ponds and the addition of chloroform pumping wells TW 4-1, TW 4-2, and TW 4-11.
Regardless of whether TW 4-6 can be demonstrated to be within the hydraulic capture of TW 4-4,
pumping TW4-4 helps to reduce chloroform migration to TW4-6, TW4-26, and other
downgradient locations by the mechanisms discussed above. The addition of chloroform
pumping well TW 4-41 is expected to enhance the beneficial effects of pumping in the vicinity of
TW4-4.
Likewise, pumping at other productive upgradient locations has a beneficial impact on
downgradient chloroform even if the downgradient chloroform is not completely within the
hydraulic capture of the productive upgradient well(s). For example, pumping at MW-26 likely
reduced chloroform concentrations at TW4-16 from a maximum of 530 µg/L in the second
quarter of 2004 to less than 70 µg/L by the fourth quarter of 2005, and maintained concentrations
below 70 µg/L until the second quarter of 2014, even though TW4-16 appears to be beyond the
hydraulic capture of MW-26. Furthermore, the overall hydraulic capture of the chloroform
pumping system has expanded since initiation of pumping at wells TW4-1, TW4-2, TW4-11
TW4-21 and TW4-37 during the first half of 2015, and since initiation of pumping at TW4-39 in
the second half of 2016. Operation of these additional wells may have reversed the increase in
concentration at TW4-16 which dropped from 387 µg/L in the fourth quarter of 2014 to less than
70 µg/L in the second quarter of 2015. Chloroform at TW4-16 has been above and below 70
µg/L since the second quarter of 2015 and was detected at 54.5 µg/L this quarter.
Chloroform exceeding 70 µg/L was detected in the second quarter of 2013 at TW4-29, installed
during the first quarter of 2013 and located south of TW4-27 and east of TW4-26. With respect
to historic groundwater flow directions implied by historic groundwater elevations in this area,
22
TW4-29 is positioned generally cross-gradient of TW4-4 and TW4-6. As discussed in Section
4.1.1, chloroform detected at TW4-29 may have migrated around the low permeability area
defined by TW4-27, TW4-14 and TW4-36. The apparent migration pathway from TW4-4 to
TW4-29 is consistent with chloroform exceeding 70 µg/L detected in the fourth quarter of 2013
at TW4-33, installed during the third quarter of 2013 and located between TW4-4 and TW4-29.
Chloroform concentrations at TW4-33 that are lower than concentrations at TW4-29, and the
likelihood that a pathway exists from TW4-4 to TW4-33 to TW4-29, suggest that concentrations
in the vicinity of TW4-33 were likely higher prior to initiation of TW4-4 pumping. TW4-4
pumping (augmented by pumping at adjacent new well TW4-41) is likely to eventually reduce
chloroform at both TW4-33 and TW4-29 by cutting off the source. The impact at TW4-33 is
expected to be greater than at TW4-29 because TW4-33 is in closer proximity to TW4-4 (and
TW4-41) pumping. Such behavior is expected by analogy with the decreases in chloroform
concentrations at TW4-6 and TW4-26 that occurred once TW4-4 pumping began. However,
concentrations at both TW4-29 and TW4-33 were relatively stable (rather than decreasing) for
several quarters after installation. Concentrations at TW4-29 appear to be on an upward trend
since the third quarter of 2014. As discussed in Section 4.1.1, although decreasing concentration
trends at both wells are eventually expected to occur, relatively stable chloroform at TW4-33 and
increases in concentration at TW4-29 since the third quarter of 2014 suggest that chloroform
migration has been arrested at TW4-33 by TW4-4 pumping and that increasing chloroform at
downgradient well TW4-29 results from a remnant of the plume that continues to migrate
downgradient (toward TW4-30, which bounds to plume to the east). The influence of TW4-4
pumping at the distal end of the plume is consistent with generally decreasing water levels at
both TW4-29 and TW4-33. However, as discussed in Section 4.1.1, decreasing water level trends
are also consistent with reduced wildlife pond seepage. The decay of the groundwater mound
associated with the southern wildlife pond, which is 3 to 4 times closer to the southern extremity
of the chloroform plume than the northern ponds, is likely to have an impact on water levels
within and adjacent to this portion of the plume.
At TW4-6 and TW4-26, generally decreasing water level trends (since about the fourth quarter
of 2013), and increased concentrations (since the first quarter of 2014 and the third quarter of
2016, respectively) are also consistent with reduced wildlife pond seepage, in particular reduced
seepage from the southern wildlife pond. As the groundwater mound associated with the
southern pond decays, groundwater flow directions in the southern extremity of the plume are
likely to become more southerly, and plume migration is likely to turn more to the south. An
increasingly southerly direction of plume migration is consistent with increasing concentrations
at TW4-26 (from less than 10 µg/L in the third quarter of 2016 to 960 µg/L this quarter).
In addition, as in the area near TW4-29 and TW4-33, generally decreasing concentrations at
TW4-6 since the third quarter of 2015, and generally increasing concentrations at TW4-26 since
the third quarter of 2016, suggest that TW 4-4 pumping has arrested chloroform migration
between TW4-4 and TW4-6, and that increasing chloroform at TW4-26 results from a remnant
of the plume that continues to migrate south from TW4-6 to TW4-26.
Furthermore, detectable chloroform concentrations at TW 4-14 (since the fourth quarter of 2014)
and TW4-27 (since the third quarter of 2015) suggest ongoing, but slow, downgradient migration
23
of chloroform from the distal end of the plume into the low permeability materials penetrated by
these wells.
Chloroform analytical results from TW4-35 and TW4-36 (as discussed in Section 4.2.3)
demonstrate that chloroform is bounded to the southeast ofTW4-29 and to the east of TW4-8.

over time.
4.2.3 Interpretation of Analytical Data
Comparing the chloroform analytical results to those of the previous quarter, as summarized in
the tables 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, TW4-1, TW4-2, TW4-21, TW4-24 and TW4-39;
b) Chloroform concentrations decreased by more than 20% in the following wells
compared to last quarter: TW4-6, TW4-8, TW4-10, TW4-16, TW4-20, TW4-22, TW4-
33 and TW4-40;
c) Chloroform concentrations have remained within 20% in the following wells compared
to last quarter: MW-4, TW4-4, TW4-5, TW4-7, TW4-9, TW4-11, TW4-14, TW4-18,
TW4-19, TW4-26, TW4-27, TW4-29, TW4-30 and TW4-37;
d) Chloroform concentrations have remained non-detect in the following wells: MW-32,
TW4-3, TW4-12, TW4-13, TW4-23, TW4-25, TW4-28, TW4-31, TW4-32, TW4-34,
TW4-35, TW4-36 and TW4-38; and
e) The chloroform concentration at new well TW4-41 was 1,400 µg/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
24
variations are within the range typical for sampling and analytical error. Wells MW-26, TW4-l,
TW4-2, TW4-6, TW4-8, TW4-10, TW4-16, TW4-20, TW4-21, TW4-22, TW4-24, TW4-33,
TW4-39 and TW4-40 had changes in concentration greater than 20%. Of these, MW-26, TW4-1,
TW4-2, TW4-20, TW4-21 and TW4-39 are chloroform pumping wells; and TW4-22 and TW4-
24 are nitrate pumping wells. TW4-6 is located adjacent to chloroform pumping well TW4-4;
TW4-8 is located adjacent to chloroform pumping well MW-4; TW4-10 is located adjacent to
chloroform pumping wells MW-26 and TW4-39; TW4-16 is located adjacent to chloroform
pumping wells TW4-11 and MW-26; and TW4-33 is located adjacent to chloroform pumping
wells TW 4-4 and TW 4-41. Fluctuations in concentrations at both chloroform and nitrate
pumping wells and wells adjacent to pumping wells likely result in pa11 from changes in
pumping.
TW 4-6 and TW 4-40 are also located within the southern extremity of the plume, and TW 4-33 is
located near the eastern extremity of the plume. Fluctuations in concentrations at these wells are
expected based on their locations near the plume margins.
Chloroform pumping wells TW4-11, TW4-19, TW4-20, TW4-37 and TW4-39; and nitrate
pumping well TW4-22, had the highest detected chloroform concentrations of 2,800, 2,980,
12,000, 14,400, 7,160 and 3,010 µg/L, respectively. Since last quarter, the chloroform
concentrations in TW4-11 decreased from 3,090 to 2,800 µg/L; TW4-19 increased from 2,640 to
2,980 µg/L; TW4-20 decreased from 15,400 µg/L to 12,000 µg/L, and TW4-39 increased from
2,870 to 7,160 µg/L. The chloroform concentration in TW4-22 decreased from 4,530 to 3,010
µg/L; and TW4-37 increased from 12,900 µg/L to 14,400 µg/L. The concentration in pumping
well TW4-21 increased from 421 to 532 µg/L and the chloroform concentration in nitrate
pumping well TW4-24 increased from 24.9 to 49.2 µg/L. TW4-24 remains just outside the
chloroform plume. Nitrate pumping well TW4-25 remained non-detect. TW4-25, located north
of TW4-21, bounds the chloroform plume to the north.
Chloroform at TW4-8 (which was non-detect from the first quarter of 2008 through the fourth
quarter of 2013) decreased from 220 µg/L to 155 µg/L. TW4-8 is located immediately east of
chloroform pumping well MW-4, where chloroform was detected at a concentration of 1,240
µg/L. From the first quarter of 2005 through the fourth quarter of 2013, the plume boundary
remained between MW-4 and TW4-8. The occurrence of elevated chloroform at TW4-8 is likely
related to its location along the eastern plume boundary immediately east of pumping well MW-
4. Changes in the plume boundary near TW4-8 are expected to result from changes in pumping
and reduced dilution resulting from cessation of water delivery to the northern wildlife ponds.
Chloroform at TW4-8 is bounded to the north by TW4-3 (non-detect), to the northeast by TW4-
13 (non-detect), to the east by TW4-36 (non-detect), and to the southeast by TW4-14 (5.1 µg/L).
Chloroform at TW4-29 (located at the southeastern tip of the plume, to the east of TW4-26 and
to the south of TW4-27) decreased from 533 µg/L to 474 µg/L, and chloroform at TW4-30,
located immediately downgradient of TW4-29, increased slightly from approximately 16.4 µg/L
to approximately 16.9 µg/L. Chloroform at TW4-14 decreased from 5.8 µg/L to 5.1 µg/L and
chloroform at TW4-27 decreased from approximately 6.9µg/L to approximately 5.9 µg/L.
Concentration trends at these wells are generally consistent with ongoing, but slow,
downgradient migration of chloroform at these locations. Chloroform at TW4-29 is bounded to
25
the north by TW4-27 (5.9 µg/L), to the east by TW4-30 (16.9 µg/L), to the southeast by TW4-35
(non-detect), to the south by TW4-34 (non-detect), and to the west by TW4-23 (non-detect).
Increases in concentration at TW4-26 since the third quarter of 2016 are also consistent with
continuing downgradient chloroform migration which is likely enhanced by the decay of the
groundwater mound associated with the southern wildlife pond.
Chloroform at TW4-33 (located between TW4-4 and TW4-29) showed a decrease in
concentration, from approximately 128 µg/L to 88 µg/L. Chloroform at TW4-33 is bounded to
the north by TW4-14 (5.1 µg/), to the east by TW4-27 (5.9 µg/L), and to the west by TW4-23
(non-detect). Recent increases in concentration at TW4-26 have widened the southeast extremity
of the plume which historically was narrow compared to more upgradient locations.
The chloroform concentration in TW4-6 decreased from 159 µg/L to 75 µg/L, but remains
within the chloroform plume boundary. Concentrations at TW4-6 exceeded 70 µg/L from the
first quarter of 2009 through the third quarter of 2010, and then remained below 70 µg/L until
the third quarter of 2014. Between initiation of pumping of TW 4-4 in the first quarter of 2010
and the second quarter of 2014, concentrations at TW4-6 showed a net decrease from 1,000 µg/L
to 10.3 µg/L. TW4-6, 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. TW4-6 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.
The relatively slow rate of chloroform migration in the vicinity of TW 4-6 in the past is
demonstrated by comparing the rate of increase in chloroform at this well to the rate of increase
in the nearest upgradient well TW4-4. Concentrations at TW4-4 increased from non-detect to
more than 2,200 µg/L within only two quarters whereas 16 quarters were required for
concentrations in TW4-6 to increase from non-detect to only 81 µg/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 orders of magnitude decrease in permeability south (downgradient) of
TW4-4. Chloroform migration rates in the vicinities of wells TW4-26, TW4-29 and TW4-33
have been expected to be relatively slow due to upgradient pumping and relatively low
permeability conditions. By analogy with the decreases in concentration at TW4-6 and TW4-26
that occurred after initiation of TW4-4 pumping, chloroform concentrations at both TW4-29 and
TW4-33 are expected to eventually trend downward.
Although changes in concentration have occurred in wells within the chloroform plume, the
boundaries of the plume have not changed significantly since the last quarter, except for slight
contractions near TW4-6, TW4-16, and TW4-40; and slight expansion near TW4-24.
Chloroform concentrations at TW4-9 decreased from approximately 159 µg/L to 134 µg/L, and
TW4-9 remains just within the plume. Except for the fourth quarter of 2014, TW4-9 was outside
the plume prior to the first quarter of 2016. The plume boundary is between TW4-9 and recently
installed well TW4-38 (non-detect) located immediately to the east-southeast. The general
26
increase at TW4-9 since the first quarter of 2016 is attributable to reduced recharge (and
dilution) from the northern wildlife ponds.
Nitrate pumping generally caused the western boundary of the northern portion of the
chloroform plume to migrate to the west toward TW4-24. Since the first quarter of 2014, TW4-
24 has been both inside and outside the plume and remains outside the plume this quarter, likely
due to initiation of TW4-37 pumping in the second quarter of 2015 and reduced productivity at
TW4-24 (since the third quarter of 2014). Since the second quarter of 2014, generally increased
concentrations at TW4-6 and TW4-16 (both of which were within the chloroform plume in the
past) indicate that the plume boundary migrated to the southwest and re-incorporated both wells.
TW4-6 remains within the plume whereas TW4-16 is again outside the plume this quarter.
General increases in concentrations at these wells beginning in the second quarter of 2014 are
likely related to reduced dilution from cessation of water delivery to the northern wildlife ponds
and more westerly flow induced by nitrate pumping. In addition, concentrations at TW4-6 are
likely influenced by reduced recharge at the southern wildlife pond and the decay of the
associated groundwater mound. A decreasing trend in chloroform concentration at TW4-6 since
the third quarter of 2015, and generally increasing concentrations at TW4-26 since the third
quarter of 2016, suggest that TW 4-4 pumping has arrested chloroform migration between TW 4-4
and TW4-6, and that increasing chloroform at TW4-26 results from a remnant of the plume that
continues to migrate south from TW4-6 to TW4-26. Initiation of pumping at new well TW4-41,
located adjacent to TW 4-4, is expected to help reduce downgradient plume expansion in this
area.
Although the nitrate pumping system may redistribute chloroform within the plume and cause
changes in the chloroform plume boundaries, continued operation of the nitrate pumping system
is expected to enhance capture associated with the chloroform pumping system. Furthermore, the
addition of chloroform wells TW4-1, TW4-2, TW4-11, TW4-21 and TW4-37 to the chloroform
pumping network in the first half of 2015; of TW4-39 in the fourth quarter of 2016; and of TW4-
41 this quarter, is expected to have a beneficial impact. Generally reduced concentrations at
TW4-6 (since the first quarter of 2015) and TW4-16 (since the fourth quarter of 2014) after
previous increases are likely the result of initiation of TW4-1, TW4-2, and TW4-11 pumping.
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, TW 4-4. 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.
Beginning in January 2013, EFRI began long term pumping of TW4-22, TW4-24, TW4-25, and
TWN-02 as required by the Nitrate CAP, dated May 7, 2012 and the Stipulated Consent Order
(the "SCO") dated December 12, 2012. Because wells TW4-22, TW4-24, and TW4-25 are
27
chloroform program wells, they are included in this report and any chloroform removal realized
as part of this pumping is calculated and included in the chloroform quarterly reports.
Beginning on January 14, 2015, EFRI began long term pumping of TW4-1, TW4-2, and TW4-ll
and began long term pumping of TW4-21 and TW4-37 on June 9, 2015. Beginning in December
2016 EFRI began long term pumping of TW4-39. Beginning in April 2018 EFRI began long
term pumping of TW 4-41.
The following information documents the operational activities during the quarter.
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, from TW4-4 on January 31, 2010, and from TW4-22, TW4-24, and TW4-25 on
January 26, 2013. Personnel from Hydro Geo Chem, 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 Chem 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, TW4-1, TW4-2, TW4-4, TW4-11, TW4-
19, MW-26, TW4-20, TW4-21,TWN-2, TW4-22, TW4-24, TW4-25, TW4-37,
TW4-39 and TW4-41 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 TW4-4, water levels in these wells have been measured weekly. From
commencement of pumping, water levels in wells TW4-1, TW4-2, TW4-ll, TW4-21, TW4-22,
TW4-24, TW4-25, TW4-37, TW4-39, TW4-41, and TWN-2 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, TW4-1, TW4-2,
TW4-ll, TW4-19, TW4-20, TW4-21, TW4-4, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39,
28
TW4-41 and TWN-2 and the monthly Depth to Water monitoring sheets for the chloroform
contaminant investigation wells and the selected temporary wells and permanent monitoring
wells are included under Tab C. Monthly depth to water measurements for the quarter are
recorded in the Field Data Worksheets included under Tab C.
5.4 Pumping Rates and Volumes
Table G-2 summarizes the recovered mass of chloroform by well per quarter and historically
since the inception of the chloroform recovery program for the active pumping wells. It is
important to note that TWN-2 is a nitrate program well and is sampled only for nitrate and
chloride as required by the nitrate program. Because TWN-2 is not sampled or analyzed for
chloroform, the mass of chloroform recovered is not calculated.
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 a holding tank. The water in the holding tank is used in the Mill processes.
The pumping rates and volumes for each of the pumping wells are shown in Table G-3.
Specific operational problems observed with the well or pumping equipment which occurred
during the quarter are noted for each well below.
Unless specifically noted below, no operational problems were observed with the well or
pumping equipment during the quarter.
5.4.1 TW4-22 and TW4-24
During the routine weekly checks on June 28, 2018 the Field Technicians noted that both TW4-
22 and TW4-24 were without power. Mill Maintenance personnel were alerted and immediately
replaced a fuse. Power was restored within several hours. No official notifications to DWMRC
were required as the issue was rectified within 24-hours of discovery.
5.5 Mass Removed and Plume Residual Mass
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 G-2, which shows the pounds of
chloroform that have been removed to date. The mass of chloroform removed from the plume
this quarter is approximately 20.1 lb., which is approximately 12% larger than the approximately
18 lb. removed last quarter. The larger rate of mass removal is attributable primarily to the
increased concentration at TW4-39 and the addition of TW4-41 to the pumping system.
The residual mass of chloroform within the plume is estimated as 1,271 lb. using the
methodology described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation
Method"). This is essentially the same as last quarter's estimate. As per Part 111.B.2 of the
GCAP, electronic files used in calculating the mass estimate are provided with this report.
Details of the procedure are provided in Tab L.
The residual mass is plotted in Figure L. l. Since the third quarter of 2015 the trend is downward;
the current quarter's estimate of 1,271 lb. is substantially lower than both the third quarter 2015
29
estimate of 1,712 lb., and the maximum of 2,261 lb. estimated for the second quarter of 2016.
Subsequent residual plume mass estimates will be calculated quarterly, added to the graph, and
the trendline updated as per Part III.B.3 of the GCAP.
As discussed in the CACME Report, the calculated chloroform mass has been generally
increasing since the cessation of water delivery to the two northern wildlife ponds in the first
quarter of 2012. These ponds are located immediately upgradient of the chloroform plume. The
increase in calculated mass results from increased plume area and increased average
concentrations within the plume. The increases in both plume area and average concentrations
are attributable to reduced dilution due to the reduction in chloroform-free wildlife pond seepage.
The general decrease in the residual mass estimates since the second quarter of 2016 suggests
stabilization. Although the residual mass estimates have generally increased since the first
quarter of 2012, the rate of mass removed per quarter by pumping has also generally increased,
in particular since the addition of 5 new pumping wells in the first half of 2015, and since the
addition of TW4-39 in the fourth quarter of 2016. Furthermore, although the pumping system is
not designed to hydraulically capture the entire plume, the proportion of the mass of the plume
under capture has historically been large. The proportion of the mass of the plume under capture
during the fourth quarters of 2012, 2013, 2014, 2015, 2016 and 2017 ranged from approximately
84% to 93%. The approximate proportion of the mass of the plume under capture this quarter is
93 %, which is slightly lower than last quarter's estimate of 96 %.
5.6 Inspections
All of the required inspections were completed and the inspection forms are included in Tab C.
S. 7 Conditions That May Affect Water Levels in Piezometers
No water was added to the any of the wildlife ponds during the quarter.
6.0 CORRECTIVE ACTION REPORT
No corrective actions were necessary for the current reporting period.
6.1 Assessment of Previous Quarter's Corrective Actions
There were no corrective actions required during the previous quarters' monitoring period.
7.0 CURRENT COMPLIANCE STATUS
7.1 Long Term Chloroform Plume Control
The chloroform plume is currently entirely within the Mill property boundary and is bounded on
all sides by wells having chloroform concentrations that are either non-detect or less than 70
µg/L (Tab J). The plume is bounded to the north by TW4-25 (non-detect); to the west and
southwest by MW-31 (non-detect), MW-32 (non-detect), TW4-23 (non-detect), and TW4-24
(approximately 49 µg/L); to the east by TW4-3 (non-detect), TW4-5 (approximately 14 µg/L),
30
TW4-13 (non-detect), TW4-14 (approximately 5 µg/L), TW4-18 (approximately 60 µg/L),
TW4-27 (approximately 6 µg/L), TW4-30 (approximately 17 µg/L), TW4-36 (non-detect) and
TW4-38 (non-detect); to the south by TW4-34 (non-detect); and to the southeast by TW4-35
(non-detect). Although TW4-26 no longer bounds the chloroform plume to the south-southwest,
MW-17 (non-detect) and MW-38 (non-detect) bound the plume to the far southwest (cross-
gradient), and MW-22 (non-detect), MW-39 (non-detect) and MW-40 (non-detect) bound the
plume far to the south (cross-to downgradient).
Because TW4-26 no longer bounds the chloroform plume to the south-southwest, TW4-40 was
installed south (downgradient) of TW4-26 during the first quarter of 2018. Because the current
quarter is the second consecutive quarter that chloroform in TW4-40 exceeded 70 µg/L,
additional action is required as discussed in Section 7.4. Otherwise, data collected to date
indicate there are sufficient chloroform monitoring and pumping wells to effectively define,
control, and monitor the plume. As noted above MW-17 (non-detect) and MW-38 (non-detect)
bound the plume to the far southwest (cross-gradient), and MW-22 (non-detect), MW-39 (non-
detect) and MW-40 (non-detect) bound the plume far to the south (cross-to downgradient).
7 .2 Well Construction, Maintenance and Operation
Part II of the GCAP specifies that EFRI must construct, maintain and operate the chloroform
wells in accordance with the specifications delineated therein. The two new wells that were
installed during the quarter as well as all previously installed wells were installed in accordance
with the GCAP requirements. The wells were maintained and operated as required. Additional
details regarding any specific pumping well operations and maintenance issues noted during the
quarter are discussed in Section 5.0 above.
7.3 Disposal of Extracted Groundwater
Part II of the GCAP requires that all extracted groundwater be disposed of in the tailings
management system or fed in the Mill process. All extracted groundwater was handled as
required by the GCAP.
7 .4 Compliance Well Performance
Part ILG of the GCAP states that an exceedance of the compliance well performance standard is
defined as the presence of chloroform in any compliance monitoring well in excess of 70 ug/L
for two or more quarters.
The compliance well chloroform concentrations were below the 70 ug/L except for TW 4-40. As
noted above, an exceedance is defined as the presence of chloroform in any compliance
monitoring well in excess of 70 ug/L for two or more quarters. The previously rep01ted
chloroform concentration for TW 4-40 was 248 ug/L and the current concentration is 131 ug/L.
Because an exceedance of chloroform in TW 4-40 has been reported two or more consecutive
quarters, an Exceedance Notice and Plan and Time Schedule are required and will be submitted
in accordance with the schedule required by the GCAP. A copy of the Exceedance Notice is
included in Tab N.

7 .5 Chloroform Plume Monitoring for Wells within 500 Feet of the Property Boundary
Currently there are no compliance wells within 500 feet of the property boundary.
8.0 CONCLUSIONS AND RECOMMENDATIONS
The residual mass of chloroform within the plume is estimated as 1,271 lb. using the
methodology described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation
Method"). This is approximately approximately the same as last quarter's estimate. The mass of
chloroform removed from the plume this quarter is approximately 20.1 lb., which is
approximately 12% larger than the approximately 18 lb. removed last quarter. The larger rate of
mass removal is attributable primarily to the increased concentration at TW4-39 and the addition
of TW4-41 to the pumping system.
The chloroform plume is currently entirely within the Mill property boundary and is bounded on
all sides by wells having chloroform concentrations that are either non-detect or less than 70
µg/L (Tab J). The plume is bounded to the north by TW4-25 (non-detect); to the west and
southwest by MW-31 (non-detect), MW-32 (non-detect), TW4-23 (non-detect), and TW4-24
(approximately 49 µg/L); to the east by TW4-3 (non-detect), TW4-5 (approximately 14 µg/L),
TW4-13 (non-detect), TW4-14 (approximately 5 µg/L), TW4-18 (approximately 60 µg/L),
TW4-27 (approximately 6 µg/L), TW4-30 (approximately 17 µg/L), TW4-36 (non-detect) and
TW4-38 (non-detect); to the south by TW4-34 (non-detect); and to the southeast by TW4-35
(non-detect). Although TW4-26 no longer bounds the chloroform plume to the south-southwest,
MW-17 (non-detect) and MW-38 (non-detect) bound the plume to the far southwest (cross-
gradient), and MW-22 (non-detect), MW-39 (non-detect) and MW-40 (non-detect) bound the
plume far to the south (cross-to downgradient).
Because TW4-26 no longer bounds the chloroform plume to the south-southwest, TW4-40 was
installed south (downgradient) of TW4-26 during the first quarter of 2018. Because the current
quarter is the second consecutive quarter that chloroform in TW4-40 exceeded 70 µg/L,
additional action is required as discussed in Section 7.4. Otherwise, data collected to date
indicate there are sufficient chloroform monitoring and pumping wells to effectively define,
control, and monitor the plume. As noted above, MW-17 (non-detect) and MW-38 (non-detect)
bound the plume to the far southwest (cross-gradient), and MW-22 (non-detect), MW-39 (non-
detect) and MW-40 (non-detect) bound the plume far to the south (cross-to downgradient).
The water level contour maps for the second quarter, 2018 indicate effective capture of water
containing high chloroform concentrations in both the northwestern and eastern ( vicinity of MW-
4) portions of the chloroform plume. Capture in the vicinity of MW-4 was enhanced by start-up
of chloroform pumping wells TW 4-1, TW 4-2, and TW 4-11 during the first quarter of 2015. The
start-up of chloroform pumping wells TW4-21 and TW4-37 during the second quarter of 2015,
of TW4-39 during the fourth quarter of 2016; and of TW4-41 this quarter has also contributed to
capture and chloroform removal effectiveness.
Although pumping began in the first quarter of 2010, a well-defined capture zone is not clearly
evident at chloroform pumping well TW4-4. The capture zone associated with TW4-4 is likely
32
obscured by the low water level at adjacent well TW4-14 and the two orders of magnitude
decrease in permeability south of TW4-4. However, between the first quarter of 2010 and the
second quarter of 2014, decreases in chloroform concentrations and the rate of water level rise at
TW4-6 (located downgradient of TW4-4) likely resulted from TW4-4 pumping. In addition,
increased drawdown at TW4-4 related to pumping at adjacent new well TW4-41 has generally
increased drawdowns in this area and has contributed to southerly expansion of total pumping
system capture this quarter.
Cones of depression associated with the nitrate pumping wells became evident as of the fourth
quarter of 2013, and capture associated with the nitrate pumping is expected to continue to
develop. Overall, the apparent capture area of the combined chloroform and nitrate pumping
systems is similar to last quarter.
'Background' flow through the chloroform plume was calculated as approximately 3.4 gpm as
presented in CACME Report (See HGC, March 31, 2016: Corrective Action Comprehensive
Monitoring Evaluation Report, White Mesa Uranium Mill, Near Blanding, Utah). Pumping from
wells within and immediately adjacent to the chloroform plume during the current quarter (from
wells MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22,
TW4-24, TW4-37, and TW4-39) is approximately 5.3 gpm, which exceeds the calculated
background flow by 1.9 gpm or 56%, and is considered adequate at the present time.
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.
MW-26, TW4-1, TW4-2, TW4-6, TW4-8, TW4-10, TW4-16, TW4-20, TW4-21, TW4-22,
TW4-24, TW4-33, TW4-39 and TW4-40 had changes in concentration greater than 20%. Of
these, MW-26, TW4-1, TW4-2, TW4-20, TW4-21 and TW4-39 are chloroform pumping wells;
and TW4-22 and TW4-24 are nitrate pumping wells. TW4-6 is located adjacent to chloroform
pumping well TW4-4; TW4-8 is located adjacent to chloroform pumping well MW-4; TW4-10
is located adjacent to chloroform pumping wells MW-26 and TW4-39; TW4-16 is located
adjacent to chloroform pumping wells TW4-11 and MW-26; and TW4-33 is located adjacent to
chloroform pumping wells TW 4-4 and TW 4-41.
Fluctuations in concentrations at both chloroform and nitrate pumping wells and wells adjacent
to pumping wells likely result in part from changes in pumping. TW4-6 and TW4-40 are also
located within the southern extremity of the plume, and TW4-33 is located near the eastern
extremity of the plume. Fluctuations in concentrations at these wells are expected based on their
locations near the plume margins. In addition, changes in concentrations at chloroform wells are
expected to result from continued operation of nitrate pumping wells as the capture associated
with nitrate pumping expands and flow directions change locally.
Chloroform pumping wells TW4-11, TW4-19, TW4-20, TW4-37 and TW4-39; and nitrate
pumping well TW4-22, had the highest detected chloroform concentrations of 2,800, 2,980,
12,000, 14,400, 7,160 and 3,010 µg/L, respectively. Since last quarter, the chloroform
concentrations in TW4-11 decreased from 3,090 to 2,800 µg/L; TW4-19 increased from 2,640 to
2,980 µg/L; TW4-20 decreased from 15,400 µg/L to 12,000 µg/L, and TW4-39 increased from
33
2,870 to 7,160 µg/L. The chloroform concentration in TW4-22 decreased from 4,530 to 3,010
µg/L; and TW4-37 increased from 12,900 µg/L to 14,400 µg/L. The concentration in pumping
well TW4-21 increased from 421 to 532 µg/L and the chloroform concentration in nitrate
pumping well TW4-24 increased from 24.9 to 49.2 µg/L. TW4-24 remains just outside the
chloroform plume. Nitrate pumping well TW4-25 remained non-detect. TW4-25, located north
of TW 4-21, bounds the chloroform plume to the north.
Chloroform at TW4-8 (which was non-detect from the first quarter of 2008 through the fourth
quarter of 2013) decreased from 220 µg/L to 155 µg/L. TW4-8 is located immediately east of
chloroform pumping well MW-4, where chloroform was detected at a concentration of 1,240
µg/L. From the first quarter of 2005 through the fourth quarter of 2013, the plume boundary
remained between MW-4 and TW4-8. The occurrence of elevated chloroform at TW4-8 is likely
related to its location along the eastern plume boundary immediately east of pumping well MW-
4. Changes in the plume boundary near TW4-8 are expected to result from changes in pumping
and reduced dilution resulting from cessation of water delivery to the northern wildlife ponds.
Chloroform at TW4-8 is bounded to the north by TW4-3 (non-detect), to the northeast by TW4-
13 (non-detect), to the east by TW4-36 (non-detect), and to the southeast by TW4-14 (5.1 µg/L)
Detectable chloroform concentrations at TW4-14 (since the fourth quarter of 2014) and TW4-27
(since the third quarter of 2015) are consistent with continued, but slow, downgradient migration
of chloroform from the distal end of the plume (near TW4-29 and TW4-33) into the low
permeability materials penetrated by TW4-14 and TW4-27. Chloroform at TW4-14 decreased
from approximately 5.8 µg/L to 5.1 µg/L and chloroform at TW4-27 decreased from
approximately 7 µg/L to approximately 6 µg/L.
Chloroform at TW4-29 (located at the southeastern tip of the plume, to the east of TW4-26 and
to the south of TW4-27) decreased from 533 µg/L to 474 µg/L, and chloroform at TW4-30,
located immediately downgradient of TW4-29, increased slightly from approximately 16.4 µg/L
to approximately 16.9 µg/L. These changes in concentration are also consistent with ongoing,
but slow, downgradient migration of chloroform at these locations. Chloroform at TW4-29 is
bounded to the north by TW4-27 (5.9 µg/L), to the east by TW4-30 (16.9 µg/L), to the southeast
by TW4-35 (non-detect), to the south by TW4-34 (non-detect), and to the west by TW4-23 (non-
detect). Increases in concentration at TW4-26 since the third quarter of 2016 are also consistent
with continuing, but generally slow, downgradient chloroform migration which is likely
enhanced by the decay of the groundwater mound associated with the southern wildlife pond.
Chloroform at TW4-33 (located between TW4-4 and TW4-29) showed a decrease in
concentration, from approximately 128 µg/L to 88 µg/L. Chloroform at TW4-33 is bounded to
the north by TW4-14 (5.1 µg/), to the east by TW4-27 (5.9 µg/L), and to the west by TW4-23
(non-detect). Recent increases in concentration at TW 4-26 have widened the southeast extremity
of the plume which historically was narrow compared to more upgradient locations.
Although changes in concentration have occurred in wells within the chloroform plume, the
boundaries of the plume have not changed significantly since the last quarter, except for slight
contractions near TW4-6, TW4-16, and TW4-40; and slight expansion near TW4-24.
34
Chloroform concentrations at TW4-9 decreased from approximately 159 µg/L to 134 µg/L, and
TW4-9 remains just within the plume. Except for the fourth quarter of 2014, TW4-9 was outside
the plume prior to the first quarter of 2016. The plume boundary is between TW4-9 and recently
installed well TW4-38 (non-detect) located immediately to the east-southeast. The general
increase at TW4-9 since the first quarter of 2016 is attributable to reduced recharge (and
dilution) from the northern wildlife ponds.
Nitrate pumping generally caused the western boundary of the northern portion of the
chloroform plume to migrate to the west toward TW4-24. Since the first quarter of 2014, TW4-
24 has been both inside and outside the plume and remains outside the plume this quarter, likely
due to initiation of TW4-37 pumping in the second quarter of 2015 and reduced productivity at
TW4-24 (since the third quarter of 2014). Since the second quarter of 2014, generally increased
concentrations at TW4-6 and TW4-16 (both of which were within the chloroform plume in the
past) indicate that the plume boundary migrated to the southwest and re-incorporated both wells.
Both remain within the plume this quarter. Increases at these wells beginning in the second
quarter of 2014 are likely related to reduced dilution from cessation of water delivery to the
northern wildlife ponds and more westerly flow induced by nitrate pumping. In addition,
concentrations at TW 4-6 may be influenced by reduced recharge at the southern wildlife pond
and the decay of the associated groundwater mound. A decreasing trend in chloroform
concentration at TW4-6 since the third quarter of 2015, and generally increasing concentrations
at TW4-26 since the third quarter of 2016, suggest that TW4-4 pumping has arrested chloroform
migration between TW4-4 and TW4-6, and that increasing chloroform at TW4-26 results from a
remnant of the plume that continues to migrate south from TW4-6 to TW4-26.
Although the nitrate pumping system may redistribute chloroform within the plume and cause
changes in the chloroform plume boundaries, continued operation of the nitrate pumping system
is expected to enhance capture associated with the chloroform pumping system. Furthermore, the
addition of chloroform wells TW4-1, TW4-2, TW4-11, TW4-21 and TW4-37 to the chloroform
pumping network in the first half of 2015; of TW4-39 in the fourth quarter of 2016; and of TW4-
41 this quarter is expected to have a beneficial impact. Generally reduced concentrations at
TW4-6 (since the first quarter of 2015) and TW4-16 (since the fourth quarter of 2014) after
previous increases are likely the result of initiation of TW 4-1, TW 4-2, and TW 4-11 pumping.
Continued operation of chloroform pumping wells 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, helps to reduce downgradient chloroform migration by removing
chloroform mass and reducing hydraulic gradients, thereby allowing natural attenuation to be
more effective. Continued operation of chloroform pumping well TW4-4, augmented by
pumping at adjacent new well TW4-41, is recommended to improve capture of chloroform to the
extent practical in the southern portion of the plume. The overall decrease in chloroform
concentrations at TW4-6 from 1,000 µg/L in the first quarter of 2010 to 10.3 µg/L in the second
quarter of 2014 is likely related to pumping at TW4-4. The decrease in the long-term rate of
water level rise at TW 4-6 once TW 4-4 pumping began, which suggests that TW 4-6 is within the
hydraulic influence of TW4-4, is also consistent with the decrease in chloroform concentrations
at TW4-6 between the first quarter of 2010 and the second quarter of 2014. The decreasing trend
in water levels beginning in 2014 and, as noted above, the generally decreasing chloroform
35
concentrations since the first quarter of 2015 at TW4-6 are also attributable in part to TW4-4
pumping. Continued operation of TW4-l, TW4-2, TW4-ll, TW4-21, TW4-37 and TW4-39 is
recommended because pumping these wells has increased overall capture and improved
chloroform mass removal rates. Continued pumping of new well TW4-41 is also recommended
to further enhance capture and increase mass removal rates.
Furthermore, because of the influence of TW4-4 pumping (now augmented by TW4-41
pumping), and by analogy with the concentration decreases at TW4-6 and TW4-26 that occurred
after initiation of TW4-4 pumping, chloroform concentrations at TW4-29 and TW4-33 are
expected to eventually trend downward. Since installation in 2013, however, concentrations at
TW4-33 appear to be relatively stable to decreasing, while, since the third quarter of 2014,
concentrations at TW4-29 appear to be on an upward trend. The relatively stable chloroform at
TW4-33 and recent increases in concentration at TW4-29 suggest that chloroform migration has
been arrested at TW4-33 by TW4-4 pumping and that increasing chloroform at downgradient
well TW4-29 results from a remnant of the plume that continues to migrate downgradient
(toward TW4-30, which bounds to plume to the east). The influence of TW4-4 pumping at the
distal end of the plume is consistent with decreasing water levels at both TW4-29 and TW4-33.
Continued evaluation of trends at TW4-29 and TW4-33 will be provided in subsequent quarters.
EFRI and its consultants have raised the issues and potential effects associated with cessation of
water delivery to the northern wildlife ponds in March, 2012 during discussions with DWMRC
in March 2012 and May 2013. While past recharge from the ponds has helped limit many
constituent concentrations within the chloroform and nitrate plumes by dilution, the associated
groundwater mounding has increased hydraulic gradients and contributed to plume migration.
Since use of the northern wildlife ponds ceased in March 2012, the reduction in recharge and
decay of the associated groundwater mound are expected to increase constituent concentrations
within the plumes while reducing hydraulic gradients and rates of plume migration. Recent
increases in chloroform concentrations at TW4-6, TW4-8, TW4-9, and TW4-16 are likely related
in part to reduced dilution. As discussed above, increases in concentration at TW4-26 since the
third quarter of 2016 that are consistent with continuing downgradient chloroform migration are
also likely enhanced by the decay of the groundwater mound associated with the southern
wildlife pond.
The net impact of reduced wildlife pond recharge is expected to be beneficial even though it is
also expected to result in higher concentrations that will persist until continued mass reduction
via pumping and natural attenuation ultimately reduce concentrations. Temporary increases in
chloroform concentrations are judged less important than reduced chloroform migration rates.
The actual impacts of reduced recharge on concentrations and migration rates will be defined by
continued monitoring.
9.0 ELECTRONIC DATA FILES AND FORMAT
EFRI has provided to the Executive Secretary an electronic copy of the laboratory results for
groundwater quality monitoring conducted under the chloroform contaminant investigation
during the quarter, in Comma Separated Values format. A copy of the transmittal e-mail is

RE: 2nd Quarter Chloroform 2018
Dear Garrin Palmer: Lab Set ID: 1805254
American West Analytical Laboratories received sample(s) on 5/10/2018 for the analyses
presented in the following report.
American West Analytical Laboratories (A WAL) is accredited by The National
Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is
state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,
Digitally signed by Jose G.

RE: 2nd Quarter Chloroform 2018
Dear Garrin Palmer: Lab Set ID: 1806233
American West Analytical Laboratories received sample(s) on 6/12/2018 for the analyses
presented in the following report.
American West Analytical Laboratories (AWAL) is accredited by The National
Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is
state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,
Digitally signed by Jose G.

RE: 2nd Quarter Chloroform 2018
Dear Garrin Palmer: Lab Set ID: 1806343
American West Analytical Laboratories received sample(s) on 6/15/2018 for the analyses
presented in the following report.
American West Analytical Laboratories (AWAL) is accredited by The National
Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is
state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope 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.
This is a revision to a report originally issued 6/29/2018. Information herein supersedes
that of the previously issued reports. Pages 1, 6, 30, and 79-82 have been revised.
Nitrate/Nitrite ( as N) on sample 1806343-023B has been reanalyzed.
Thank You,

General Set Comments: Multiple target analytes were 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): Chloromethane was observed above the reporting limit on
sample MB VOC-1 061818A. The MB was acceptable, as any associated samples
do not have results above the reporting limit/PQL. No other 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 / Matrix Spike Duplicate (MS/MSD): All percent recoveries and
RPDs (Relative Percent Differences) were inside established limits, with the
following exceptions: The MS and MSD percent recoveries on chloroform were
outside of control limits on sample l 806343-032C due to suspected sample non-
homogeneity or matrix interference.
Surrogates: All surrogate recoveries were within established limits.
Corrective Action: None required.

The QAP states that turbidity should be less than 5 Nephelometric Turbidity Units ("NTU") prior to sampling unless the well is characterized by water that has a higher turbidity. The QAP does not require that turbidity measurements be less than 5 NTU prior to
sampling. As such, the noted observations regarding turbidity measurements less than 5 NTU are included for information purposes only.

Re: State of Utah Stipulation and Consent Order ("SCO") Docket Number UGW-20-01
White Mesa Uranium Mill -Energy Fuels Resources (USA) Inc. ("EFRI") Notice Pursuant
to Part 11.H.1 of the Groundwater Corrective Action Plan ("GCAP") included as
Attachment 1 to the SCO
Dear Mr. Anderson:
EFRI performed second quarter 2018 chloroform monitoring during the period from April 1, to June 30,
2018 under the September 14, 2015 GCAP, included as Attachment 1 to the duly executed SCO.
Part ILG of the GCAP states that "An exceedance shall be defined as the presence of chloroform in any
Compliance Monitoring Well in excess of the Table 2 Groundwater Corrective Action Limit ("GCAL")
(70 ug/1) for two or more consecutive quarters." Further, Part II.H.1) states that "At any time EFR[IJ
submits a quarterly report that demonstrates an exceedance (second quarter of chloroform exceedance),
EFR[I] will provide a written exceedance notice to the Director ("Exceedance Notice") for all wells that
have demonstrated such an exceedance." Pursuant to Part II.H.1 of the GCAP, please note that the
concentrations of chloroform in TW4-40 exceeded the respective GCAL of 70 ug/L for two or more
consecutive quarters as noted on Table 1 attached.
This letter serves as the Exceedance Notice required pursuant to Part II.H.1) of the GCAP.
Part II.H.2) of the GCAP requires that within 60 days after the time of submittal of a quarterly report that
demonstrates an exceedance, EFRI will provide a plan and schedule for remedial actions to address
excursion for Director approval. A Plan and Time Schedule as required by II.H.2) will be submitted
under separate cover within the timeframe specified.
If you should have any questions regarding this submittal please contact me at [phone].
