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 paities 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 third quarter of 2021 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, TW4-21, MW-26, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39,
TW4-40, 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 TW4-28 TW4-37
TW4-1 TW4-10 TW4-19 TW4-29 TW4-38
TW4-2 TW4-11 TW4-21 TW4-30 TW4-39
TW4-3 TW4-12 TW4-22 TW4-31 TW4-40
TW4-4 TW4-13 TW4-23 TW4-32 TW4-41

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 7.6, dated August 22, 2019.
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, TW4-21, TW4-37, TW4-39,
TW4-40, 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, August 15, 2017, July 23, 2018, May 14, 2019, and August 22,
2019. The revised Groundwater QAP and Chloroform QAP, Revision 7.6 were approved by
DWMRC on September 10, 2019.
The sampling methodology, equipment and decontamination procedures used in the chloroform
contaminant investigation, as summarized below, are consistent with the approved QAP 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;
3
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, 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, Dissolved Oxygen ("DO") and water
temperature
2. Purging two casing volumes with stable field parameters for specific conductivity,
turbidity, pH, redox potential, DO, 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
4
the samples as described below. If the well does not have a dedicated pump, a Grundfos pump
(9 -10 gpm pump) is then lowered to the screened interval in the well and purging is started.
The purge rate is measured for the well by using a calibrated 5 gallon bucket. This purging
process is repeated at each well location moving from least contaminated to the most
contaminated well. All wells are capped and secured prior to leaving the sampling location.
Wells with dedicated pumps are sampled when the pump is in the pumping mode. If the pump is
not pumping at the time of sampling, it is manually switched on by the Mill Personnel. The well
is pumped for approximately 5 to 10 minutes prior to the collection of the field parameters. Per
the approved QAP, one set of parameters is collected. Samples are collected following the
measurement of one set of field parameters. 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 hailers.
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.

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 ("AWAL"). Table
1 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 fifteen 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 QNQuality 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
6
samples collected and analyzed is provided in Section 3.1. Discussion of adherence to Mill
sampling Standard Operating Procedures ("SOPs") is provided in Section 3.2. Analytical
completeness review results are provided in Section 3.3. The steps and tests applied to check
laboratory data QA/QC are discussed in Sections 3.4.4 through 3.4.9 below.
The analytical 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.
7
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
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 Parameter (within 10% RPD)
Wells TW4-5, TW4-8, TW4-9, TW4-16, MW-32, TW4-18, TW4-23, TW4-32, and TW4-38
were sampled after two casing volumes were removed. Field parameters (pH, specific
conductivity, turbidity, water temperature, DO, 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, TW4-36, and TW4-42 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. 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, TW4-21, TW4-22, TW4-24,
TW4-25, TW4-37, TW4-39, TW4-40, 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.
8
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 requirements resulted in the
observations noted below. The QAP requirements in Attachment 2-3 specifically state that field
parameters must be stabilized to within 10% over at least 2 consecutive measurements 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, TW4-16, MW-32, TW4-18, TW4-32, TW4-37, and TW4-38 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 report 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.
9
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. All of the trip blank samples were
nondetect.
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.
Rinsate blank sample TW4-3R had a reported chloroform detection of 12.8 ug/L. TW4-3 was
nondetect for chloroform. The rinsate blank results for TW 4-3 were outside of acceptance limits
for the rinsate blank results.
TW4-3R was collected after decontamination and prior to the pump being used to collect any Q3
2021 chloroform samples. Because the pump was not used prior to the rinsate sample collection,
the detection is not the result of cross contamination.
Rinsate blank sample TW4-5R had a reported chloroform detection of 142.8 ug/L. TW4-5 had a
detection of chloroform of 11.2 ug/L. The rinsate blank results for TW4-5 were outside of
acceptance limits for the rinsate blank results.
10
Prior to the Q3 2021 sampling event EFRI serviced the DI water system and all filters and media
were changed. The DI blank from the on-site DI system which generates the water for rinsate
blank samples was nondetect, but has had reported concentrations in recent quarters. EFRI is
continuing the investigation of the chloroform in the DI samples. The results of this
investigation will be provided in future reports. EFRI is contacting the media and filter provider
again and looking at plumbing systems to determine if the chloroform is originating within the
physical system.
The data for all samples are usable as reported. Even if there were contribution of chloroform to
the sample results, it would bias the data high and would result in a more conservative data
application. EFRI does not believe the data quality has been affected.
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
(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
except as indicated in Tab I. The data recoveries and RPDs which are outside the laboratory
established acceptance limits do not affect the quality or usability of the data because the
recoveries and RPDs above or below the acceptance limits are indicative of matrix interference
most likely caused by other constituents in the samples. 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.
11
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 QNQC 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 laboratory reported
that a method blank reported concentrations of methylene chloride below the RL. The method
blank results did not affect any sample results and no further actions are necessary. 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.
The information from the Laboratory QNQC Summary Reports indicates that there were low
Continuing Calibration Verification ("CCV") recoveries for chloromethane. The CCV recovery
affected samples TW4-5, TW4-5R, TW4-7, TW4-8, TW4-9, TW4-10, TW4-16, MW-32, TW4-
18, TW4-29, TW4-30, TW4-33, and TW4-70. The data were flagged in accordance with the
changes specified in EPA Method 8260D. The flagging requirements are new to the revised
method and do not adversely affect the data. The data are usable for the intended purpose
because chloromethane is not frequently detected. Further, the wells listed above do not have
recent historical detections of chloromethane and the nondetect data are likely accurate.
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 northwesterly flow occurs near MW-19 and
12
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
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
13
increase constituent concentrations locally as a result of reduced wildlife pond recharge include
but are not limited to:
1) Reduced dilution -the m1xmg 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 (now abandoned);
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 subsequently added
to the chloroform pumping network: TW4-1, TW4-2, TW4-11, TW4-21 and TW4-37 (added
during 2015); TW4-39 (added during the fourth quarter of 2016); TW4-41 (added during the
second quarter of 2018); and TW4-40 (added during the second quarter of 2019). 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 were typically evident in the vicinity of all chloroform pumping
wells except TW4-4 and TW4-37, which began pumping in the first quarter of 2010 and the
second quarter of 2015, respectively. The third quarter of 2018 was the first quarter that a well-
defined cone of depression was associated with TW4-4, primarily the result of pumping at
adjacent well TW4-41.
The lack of well-defined capture associated with chloroform pumping well TW 4-4 was
consistent prior to the third quarter of 2018, 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 resulted from 1) variable permeability conditions in the vicinity of
TW4-4, and 2) historical relatively low water levels at adjacent well TW4-14.
Nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 started pumping during the first
quarter of 2013. By the fourth quarter of 2013, operation of the nitrate pumping system had
produced well-defined impacts on water levels. Water level impacts of the nitrate and chloroform
pumping systems overlap; however the long-term interaction between the nitrate and chloroform
pumping systems is evolving, and changes will be reflected in data collected during routine
monitoring.
Water level patterns near nitrate pumping 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
historically relatively low water level at TWN-7. Since 2012, water levels in TWN-7 have risen
while water levels in nearby wells have generally dropped due to pumping and the decay of the
14
northern groundwater mound. These factors have reduced water level differences between TWN-
7 and nearby wells.
As discussed above, variable permeability conditions likely contributed 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
were expected to be muted because TW4-4 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
in this area that has been attributable to past wildlife pond recharge. Between the fourth quarter
of 2007 and the fourth quarter of 2009 (just prior to the start of TW4-4 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 TW 4-4.
Water levels in wells currently within the chloroform plume south of TW4-4 (TW4-26, TW4-29,
TW4-30, TW4-33 and TW4-40) are trending generally downward. The downward trend is
evident at TW4-26, TW4-29 and TW4-33 since the fourth quarter of 2013; at TW4-30 only since
about the end of 2020; and at TW4-40 since installation in the first quarter of 2018. The water
level in TW4-6 (remaining outside the plume again this quarter) has also trended downward
since the fourth quarter of 2013. Downward trends are attributable to both the cessation of water
delivery to the wildlife ponds and pumping. Although water levels at some of the wells marginal
to the chloroform plume such as TW4-14, TW4-27 and TW4-31 were generally increasing until
about the first quarter of 2018, these water levels now appear to be relatively stable to
decreasing. Water level trends at TW4-30, which was incorporated into the chloroform plume
during the fourth quarter of 2020, have been similar to those at TW 4-27.
These spatially variable water level trends likely result from pumping 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
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 previous lack of a well-defined cone of depression associated with TW 4-4 was also
influenced by the historically relatively low water level at non-pumping well TW4-14, located
east of TW4-4 and TW4-6. Prior to 2018, although water level differences among these three
wells had diminished, and TW 4-4 has been pumping since 2010, the water level at TW 4-14 was
typically lower than the water level at TW4-6 and lower to an even greater extent than the water
level at TW4-4. However, since the first quarter of 2018, as a result of pumping at TW4-
15
4l(adjacent to TW4-4), and declining water levels at TW4-6, the water level at TW4-14 was
typically higher than the water levels at both TW4-4 and TW4-6. During the current quarter the
water level at TW4-14 (approximately 5535.3 feet above mean sea level ["ft amsl"]) is more than
5 1/z feet higher than the water level at TW4-6 (approximately 5529.7 ft amsl), and is nearly 3
feet higher than the water level at TW4-4 (approximately 5532.4 ft. amsl).
The static water levels at wells TW 4-14 and downgradient well TW 4-27 (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 TW 4-4, TW 4-6, and TW 4-
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 relatively low water level at TW4-14. The water level at TW4-26
5527.7 feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5529.7 feet
amsl) and TW4-23 (5531.6 feet amsl), as shown in the detail water level map under Tab D.
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 TW4-14 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
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.
16
The current quarterly water level at TW4-27 (approximately 5528.8 ft. amsl) is more than 6 feet
lower than the water level at TW4-14 (5535.3 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 TW 4-14 and
TW4-27 delayed responses at these locations. Until pumping started at TW4-41, water levels at
both these wells were consistently lower than in surrounding higher permeability materials even
though water levels in surrounding materials were generally decreasing due to reduced pond
seepage and pumping. Although water levels at TW4-14 and TW4-27 appear to have stabilized,
the previous rate of increase was higher at TW 4-14 due to factors that include: closer proximity
to the northern pond seepage source; and a smaller thickness of low permeability materials
separating TW4-14 from surrounding higher permeability materials. In addition, hydraulic
gradients between TW 4-14 and surrounding higher permeability materials were relatively large
and were consistently directed toward TW4-14 prior to TW4-41 pumping. Slowing of the rates
of water level increase at TW4-14 (since 2015) and TW4-27 (since early 2014), and relative
stabilization since about the first quarter of 2018, are attributable to changes in hydraulic
gradients between these wells and surrounding higher permeability materials.
In addition, water levels in this area are affected by reduced recharge at the southern wildlife
pond and the decay of the associated groundwater mound. The decay of the mound is expected to
contribute to changes in hydraulic gradients between the low permeability materials penetrated
by TW4-14 and TW4-27 and the surrounding higher permeability materials. Because TW4-27 is
closer to the southern wildlife pond than TW 4-14, changes in hydraulic gradients attributable to
decay of the southern groundwater mound are expected to impact TW4-27 sooner and to a
greater extent than TW4-14, 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
TW4-27 remain outside the plume with current quarter chloroform concentrations of less than 1
µg/L and 3.8 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
also migrated along a relatively narrow path to the southeast from the vicinity of TW4-4 to TW4-
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 about 2014, placed TW4-14 almost directly downgradient of TW4-4. Such migration was
historically possible because the water levels at TW4-29 were 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.
17
Chloroform at TW4-30 exceeded 70 µg/L for the first time during the fourth quarter of 2020 and
was detected at approximately 78 µg/L this quarter. Consequently, TW4-30 does not bound the
plume immediately to the east. However, chloroform was not detected at wells TW4-31 (located
east of TW4-27), TW4-34 (located south and cross-to downgradient of TW4-29), nor TW4-35
(located southeast and generally 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 TW4-6, TW4-23, TW4-27, TW4-34, TW4-35 and TW4-42; however, as discussed
above, TW4-30 does not bound the plume immediately to the east. Although previously
downgradient of TW4-29, due to long-term changes in water levels, TW4-30 is now
generally cross-gradient of TW4-29. TW4-6, TW4-23 and TW4-27 are generally cross-
to upgradient of TW4-29; TW4-34 is generally cross-to downgradient of TW4-29; TW4-
42 is generally cross-gradient of TW4-29; and TW4-35 is generally downgradient of both
TW4-29 and TW4-30.
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 concentrations below 70
µg/L at TW4-6 and TW4-23 (located up-to cross-gradient of TW4-26); and at TW4-34
(located generally cross-gradient of TW4-26). Chloroform has not been detected at either
TW4-23 or TW4-34. Although chloroform exceeding 70 µg/L was detected at well TW4-
40, installed approximately 200 feet south of TW4-26 in February, 2018, chloroform has
not been detected at TW 4-42, installed approximately 200 feet south of TW 4-40 in April,
2019. TW4-42 is generally downgradient of both TW4-26 and TW4-40 and bounds the
chloroform plume to the south.
Eventually, TW4-4 pumping, enhanced by operation of adjacent pumping well TW4-41, is likely
to reduce chloroform at both TW4-29 and TW4-33 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 TW4-
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 to decreasing (and have been decreasing since 2018). From the third quarter of
2014 until the second quarter of 2020, concentrations at TW4-29 generally increased; however
since the second quarter of 2020 concentrations appear to be relatively stable to decreasing.
Chloroform trends at TW4-29 and TW4-33 suggest that chloroform migration has been arrested
at TW4-33 by TW4-4 (and TW4-41) pumping and that increased chloroform at TW4-29 resulted
from a remnant of the plume that migrated past TW4-33 and generally toward TW4-30 (which
was previously downgradient of TW4-29, and until the fourth quarter of 2020, bounded the
18
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. Pumping at TW4-41 since
the second quarter of 2018 is expected to help maintain or enhance this decline.
Decreasing water level trends at TW4-29 and TW4-33 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 expected to impact water levels within and adjacent to this portion of the plume.
Reduced wildlife pond seepage, in particular, reduced seepage from the southern wildlife pond,
likely contributes to decreasing water level trends at both wells (since about the fourth quarter of
2013); temporarily increased concentrations at TW4-6 subsequent to the first quarter of 2014;
and increased concentrations at TW4-26 since the third quarter of 2016.
As the groundwater mound associated with the southern pond decays, groundwater flow
directions in the southern extremity of the plume have become more southerly, and plume
migration has turned more to the south. An increasingly southerly direction of plume migration
is consistent with water level changes in this area and increased concentrations at TW4-26.
In addition, generally decreasing concentrations at TW4-6 since the third quarter of 2015, and
generally increased 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 increased
chloroform at TW4-26 results from a remnant of the plume that continues to migrate south from
TW4-6 to TW4-26. The enhancement of pumping in the vicinity of TW4-4 by the start-up of
TW4-41 pumping in the second quarter of 2018 is likely to increase this apparent separation and
to have resulted in concentrations at TW4-6 dropping below 70 µg/L after the second qua1ter of
2018. Furthermore, the initiation of pumping at TW4-40 during the second quarter of 2019 is
expected to reduce or prevent chloroform migration to the south of TW 4-40.
Detectable chloroform concentrations at TW4-14 (from the fourth quarter of 2014 through the
first quarter of 2021) and at TW4-27 (since the third quarter of 2015) suggest ongoing, but slow,
downgradient migration of chloroform from the southeastern extremity of the plume (near TW4-
29 and TW4-33) into the low permeability materials penetrated by TW4-14 and TW4-27.
Pumping at TW 4-41 is expected to reduce or prevent future migration of chloroform toward
these wells.
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 second quarter of 2021, as submitted with
the Chloroform Monitoring Report for the second quarter of 2021, is attached under Tab E. A
comparison of the water table contour maps for the current quarter (third quarter of 2021) to the
water table contour maps for the previous quarter (second quarter of 2021) indicates the
following: water level changes at the majority of site wells were small ( < 1 foot); as with the
previous quarter, no significant changes to water level contours north of Cell 1 resulted from
water level measurements at recently installed temporary nitrate wells TWN-20 and TWN-21;
and water level contours have not changed significantly except in the vicinities of many of the
19
nitrate and chloroform pumping wells. Overall, total pumping capture 1s smaller than 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. Additional large expansions occurred once chloroform pumping wells
TW4-1, TW4-2, TW4-11, TW4-21 and TW4-37 became operational in 2015, and once TW4-39
became operational in the fourth quarter of 2016. Significant expansion of capture to the south
has resulted from pumping of TW4-41 since the second quarter of 2018 and from initiation of
pumping at TW 4-40 during the second quarter of 2019.
The drawdown at nitrate pumping well TW 4-24 increased by more than 2 feet this quarter.
However drawdowns at chloroform pumping wells MW-26, TW4-2, TW4-4 and TW4-21; and
nitrate pumping well 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 TW 4-11 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 smaller than last quarter.
As discussed in Section 4.1.1, pumping at chloroform well TW 4-4, which began in the first
quarter of 2010, depressed the water table near TW4-4, but a well-defined cone of depression
was not clearly evident until the third quarter of 2018, likely due to variable permeability
conditions near TW4-4 and the historically relatively low water level at adjacent well TW4-14.
The expanded cone of depression associated with TW4-4 and adjacent pumping well TW4-41
since the initiation of pumping at TW 4-41 in the second quarter of 2018 has contributed to
southerly expansion of total pumping system capture. As discussed above, southerly expansion
of capture was additionally enhanced in the second quarter of 2019 by the initiation of pumping
at TW4-40.
Water levels at Piezometers 1 and 2 decreased by up to 0.17 feet this quarter; current and past
decreases are consistent with 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 approximately 0.13 and 0.25 feet, respectively, at
TWN-1 and TWN-4 are also consistent with continuing decay of the northern groundwater
mound. The reported water level decrease of approximately 0.12 feet at both Piezometers 4 and 5
likely result primarily from reduced recharge at the southern wildlife pond.
The reported water level at MW-20 increased by nearly 2 feet. Water level variability at this well
likely results from low permeability and variable intervals between purging/sampling and water
level measurement. The reported water level increase at MW-20 partially compensates for the
reported decrease last quarter.
20
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.

elevation over time for each of the wells listed in Section 2.1.1 above.
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; TW4-4 since 2010; TW4-1,
TW4-2, TW4-11, TW4-21 and TW4-37 since 2015; TW4-39 since the fourth quarter of 2016;
TW4-41 since the second quarter of 2018; and TW4-40 since the second quarter of 2019. TW4-
20 was also operated as a pumping well from 2005 until August, 2020 when it collapsed and was
subsequently abandoned. The primary purpose of pumping the above wells is to reduce total
chloroform mass in the perched zone as rapidly as is practical.
The original pumping wells up gradient of TW 4-4 were chosen because 1) they were 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 original pumping wells resulted in the
wells having a relatively high productivity. The combination of relatively high productivity and
high chloroform concentrations allowed for a high rate of chloroform mass removal. TW 4-4 and
TW4-41 are located in a downgradient area having relatively high chloroform concentrations but
relatively small saturated thickness, and at a transition from relatively high to relatively low
permeability conditions downgradient of TW 4-4. As with the other chloroform pumping wells,
pumping TW 4-4 and TW 4-41 helps to reduce the rate of chloroform migration in downgradient
portions of the plume.
Although pumping of TW4-6 and TW4-26 (located south of TW4-4 and TW4-41) is impractical
due to low permeability and small saturated thicknesses, the permeability in the vicinity of TW 4-
40 (located south of TW4-26) is large enough to make pumping practical. TW4-40 is valuable in
that it is located within the downgradient (southern) toe of the plume and is relatively productive.
Pumping of TW4-40 is likely to more effectively reduce or prevent further downgradient plume
migration than can be expected by pumping at the more upgradient locations.
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; and near MW-26,
TW4-19, TW4-37 and TW4-39. These wells continue to remove significant quantities of
21
chloroform from the perched zone. Relatively large cones of depression are also evident in the
vicinities of wells TW4-1 and TW4-2 (near MW-4); and at TW4-11. These wells began pumping
during the first quarter of 2015. As discussed in Section 4.1.1, although chloroform pumping
well TW4-4 became operational in 2010, the drawdown associated with TW4-4 was likely less
apparent due to variable permeability conditions near TW 4-4 and the persistently low water level
at adjacent well TW4-14. However, pumping at adjacent well TW4-41 since the second quarter
of 2018 has generally increased drawdowns in this area; the third quarter of 2018 was the first
quarter that a well-defined cone of depression was associated with TW4-4. As discussed in
Section 4.1.2 the combined pumping of TW 4-4 and TW 4-41, enhanced by initiation of pumping
at TW4-40 during the second quarter of 2019, has contributed to southerly expansion of total
pumping system capture. Overall, the water level contour maps indicate effective capture of
water containing high chloroform concentrations in the vicinities of the pumping wells.
Compared to last quarter, both increases and decreases in water levels occurred at nitrate and
chloroform pumping wells, although changes in water levels in chloroform pumping wells MW-
4, TW4-1, TW4-11, TW4-19, TW4-37, TW4-39, TW4-40 and TW4-41; and nitrate pumping
wells TW4-22 and TW4-25 were less than two feet. Water level decreases occurred in
chloroform pumping wells TW4-11 (approximately 0.4 feet); TW4-19 (approximately 1 foot);
and TW4-40 (approximately 0.2 feet); and in nitrate pumping well TW4-24 (approximately 2.4
feet). Water level increases occurred in chloroform pumping wells MW-4 (approximately 0.2
feet); MW-26 (approximately 10.3 feet); TW4-1 (approximately 1.8 feet); TW4-2
(approximately 13.1 feet); TW4-4 (nearly 4.3 feet); TW4-21 (approximately 2.5 feet); TW4-37
(approximately 1 foot); TW4-39 (nearly 0.8 feet); and TW4-41 (approximately 0.8 feet); and in
nitrate pumping wells TW4-22 (nearly 0.7 feet); TW4-25 (nearly 0.7 feet); and TWN-2
(approximately 10.1 feet). The overall apparent combined capture area of the nitrate and
chloroform pumping systems is smaller than last quarter; capture decreased within the central
and northern portions of the combined pumping system due primarily to decreased drawdowns at
MW-26 and TWN-2.
The capture associated with nitrate pumping wells and chloroform pumping wells added since
the beginning of 2015 is expected to generally 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 since the third quarter of 2014 have been noted 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).
22
Decreases in productivity at TW 4-4 since the third quarter of 2016 have been addressed by the
operation of adjacent pumping well TW4-41 since the second quarter of 2018.
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, TW4-21,
TW4-22, TW4-24, TW4-37, TW4-39, TW4-40 and TW4-41) is approximately 4.9 gpm.
Pumping from TW4-20 is not included as it was abandoned in October, 2020.
The pumping calculation is based on the total volume pumped by the above wells over the 90
day quarter (633,307 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 1.5 gpm or 44 %, and is considered adequate at the present time even with the reduced
productivities of some wells. 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 TW 4-20
toward these wells. The increase in concentration at TW4-8 from non-detect to 100 µg/L in the
first quarter of 2014 is likely related to reduced dilution. The concentration at TW4-8 remained
below 70 ug/L this quarter after dropping below 70 µg/L during the first quarter of 2020. In
addition, although the chloroform concentration in TW4-6 generally decreased between the first
quarter of 2015 and the current quarter (and remains outside the plume), concentrations at TW4-
6 increased from approximately 6 µg/L in the first quarter of 2014 to 1,180 µg/L in the first
quarter of 2015 before dropping to 3.7 µg/L this quarter. The increase between the first quarter
of 2014 and the first quarter of 2015 was likely related to both reduced dilution and more
westward flow induced by nitrate pumping.
TW4-6 is located immediately south and historically cross-to downgradient of chloroform
pumping well TW 4-4. TW 4-6 has been incorporated into the chloroform plume twice: from the
first quarter of 2009 through the third quarter of 201 O; and from the third quarter of 2014 through
the second quarter of 2018. Pumping of TW4-6 (and TW4-26) is impractical because of
relatively low permeability and relatively small saturated thicknesses. However, pumping at
more productive locations upgradient of TW4-6 (such as TW4-4 and TW4-41) 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 TW 4-4 was
implemented during the first quarter of 2010 to improve capture down gradient 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 was 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 TW4-4 pumping and the second quarter of 2014. Concentrations
at these wells decreased substantially even though they did not unambiguously appear to be
23
within the hydraulic capture of TW4-4. 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 was 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 TW4-l, TW4-2, TW4-11
and TW4-41. Regardless of whether TW4-6 was demonstrably within the hydraulic capture of
TW4-4, pumping TW4-4, and relatively recently installed adjacent pumping well TW4-41, helps
to reduce chloroform migration to TW4-6, TW4-26, and other downgradient locations by the
mechanisms discussed above.
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, TW4-37, TW4-39, TW4-40 and TW4-41 since the beginning of 2015. In particular, the
addition of wells TW4-1, TW4-2, TW4-11, TW4-21, TW4-37 and TW4-39 likely halted the
mid-2013 to end of 2014 increase in concentration at TW4-16 from non-detect to 387 µg/L.
Concentrations at TW4-16 dropped from 387 µg/L in the fourth quarter of 2014 to less than 70
µg/L by the second quarter of 2015. Although chloroform at TW4-16 has been above and below
70 µg/L since 2014, and was detected at 202 µg/L this quarter, concentrations have generally
increased since 2018, likely in response to reduced dilution.
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,
TW4-29 was 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 well TW4-41) is expected to eventually
reduce chloroform at both TW4-33 and TW4-29 by cutting off the source, with the impact at
TW4-33 anticipated to be greater than at TW4-29 because TW4-33 is in closer proximity to
TW4-4 (and TW4-41) pumping. By analogy, such behavior would be consistent with the
decreases in chloroform concentrations at TW4-6 and TW4-26 that occurred once TW4-4
pumping began.
24
However, for several quarters after installation, concentrations at both TW4-29 and TW4-33
were relatively stable (rather than decreasing). Between the third quarter of 2014 and the second
quarter of 2020, concentrations at TW4-29 generally increased; subsequently concentrations
stabilized and began to decrease. Over the same time period concentrations at TW4-33 remained
generally stable to decreasing. As discussed in Section 4.1.1, decreasing concentration trends at
both wells were eventually expected to occur. Since the third quarter of 2014, TW4-33
concentrations that have been relatively stable to decreasing; and TW4-29 concentrations that
generally increased before stabilizing and subsequently decreasing; appear consistent with these
expectations. Trends at these wells suggest that chloroform migration has been arrested at TW 4-
33 by TW4-4 (and TW4-41) pumping and that previously increasing chloroform at TW4-29
resulted from a remnant of the plume that migrated past TW4-33 generally toward TW4-30
(which was previously downgradient of TW4-29 and, until the fourth quarter of 2020, bounded
the plume to the east). The influence of TW 4-4 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.
As discussed in Section 4.1.1, generally decreasing water level trends at TW4-6 and TW4-26
(since about the fourth quarter of 2013), temporarily increased concentrations at TW4-6 (since
the first quarter of 2014) and increased concentrations at TW4-26 (since the third quarter of
2016), 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 have become more
southerly, and plume migration is turning more to the south. An increasingly southerly direction
of plume migration is consistent with increased concentrations at TW4-26 (from less than 10
µg/L in the third quarter of 2016 to 927 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 increased concentrations at TW4-26 since
the third quarter of 2016, suggest that TW4-4 (and TW4-41) pumping has arrested chloroform
migration between TW4-4 and TW4-6, and that increased chloroform at TW4-26 results from a
remnant of the plume that continues to migrate south from TW 4-6 to TW 4-26. The enhancement
of pumping in the vicinity of TW4-4 by the start-up of TW4-41 pumping in the second quarter of
2018 is likely to increase this apparent separation and to have resulted in concentrations at TW4-
6 dropping below 70 µg/L beginning in the third quarter of 2018.
Furthermore, detectable chloroform concentrations at TW4-14 (from the fourth quarter of 2014
through the first quarter of 2021) and at TW4-27 (since the third quarter of 2015) suggest
ongoing, but slow, down gradient migration of chloroform from the southeastern extremity of the
plume into the low permeability materials penetrated by these wells.
Chloroform analytical results from TW4-35 (as discussed in Section 4.2.3) demonstrate that
chloroform is bounded to the southeast of TW4-29. From 2014 through 2019 chloroform
25
concentrations at TW4-8 exceeded 70 µg/L and TW4-36 (non-detect for chloroform) served as
an eastern bounding well. However, since the end of 2019, chloroform at TW4-8 remained
below 70 µg/L and continues to bound the chloroform plume to the east.

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, TW4-6, TW4-19, and TW4-24;
b) Chloroform concentrations decreased by more than 20% in the following wells
compared to last quarter: TW4-8, TW4-9, TW4-11, TW4-21, TW4-22, TW4-37 and
TW4-39;
c) Chloroform concentrations have remained within 20% in the following wells compared
to last quarter: MW-4, TW4-1, TW4-2, TW4-4, TW4-5, TW4-7, TW4-10, TW4-16,
TW4-18, TW4-26, TW4-27, TW4-29, TW4-30, TW4-33, TW4-40 and TW4-41; and
d) Chloroform concentrations have remained non-detect in the following wells: MW-32,
TW4-3, TW4-12, TW4-13, TW4-14, TW4-23, TW4-25, TW4-28, TW4-31, TW4-32,
TW4-34, TW4-35, TW4-36, TW4-38 and TW4-42.
As indicated, chloroform concentrations at many of the wells with detected chloroform were
within 20% of the values reported for the wells during the previous quarter, suggesting that
variations are within the range typical for sampling and analytical error. Wells MW-26, TW4-6,
TW4-8, TW4-9, TW4-11, TW4-19, TW4-21, TW4-22, TW4-24, TW4-37 and TW4-39 had
changes in concentration greater than 20%. Of these, MW-26, TW4-11, TW4-19, TW4-21,
TW4-37 and TW4-39 are chloroform pumping wells; and TW4-22 and TW4-24 are nitrate
26
pumping wells. TW4-6 is located adjacent to chloroform pumping wells TW4-4 and TW4-41;
TW 4-8 is located adjacent to chloroform pumping well MW-4; and TW 4-9 is located near
chloroform pumping well TW4-39. Fluctuations in concentrations at both chloroform and nitrate
pumping wells and wells adjacent to pumping wells likely result in part from changes in
pumping. In addition, fluctuations in concentrations at wells such as TW 4-9 are expected based
on their locations near the plume margins.
Chloroform pumping wells MW-26 (1,580 µg/L); TW4-2 (1,150 µg/L), TW4-11 (2,600 µg/L);
TW4-19 (4,450 µg/L); TW4-37 (10,200 µg/L); and nitrate pumping well TW4-22 (3,510 µg/L)
had the highest detected chloroform concentrations. Although pumping well TW4-20, formerly
located between pumping wells TW4-19 and TW4-37, would typically be distinguished as
having one of the highest concentrations, TW4-20 collapsed during August, 2020 and was
abandoned in October, 2020.
Since last quarter, the chloroform concentrations in MW-26 increased from 998 to 1,580 µg/L;
TW4-2 decreased from 1,160 to 1,150 µg/L; TW4-11 decreased from 3,320 to 2,600 µg/L; TW4-
19 increased from 775 to 4,450 µg/L; and TW4-37 decreased from 13,000 to 10,200 µg/L. In
addition, the chloroform concentration in chloroform pumping well TW4-21 decreased from
1,130 to 669 µg/L; the concentration in nitrate pumping well TW4-22 decreased from 4 520 to
3,510 µg/L; and the concentration in nitrate pumping well TW4-24 increa ed from 41.2 to 103
µg/L, taking it just within the plume boundary lhis qL1arter. Nitrate pumping well TW4-25
remained non-detect. TW4-25, located north of TW4-21, bound 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 20 L3) decrea ·ed from 22.3 µg/L to 17 ~lg/L and remained out ide the pJume. TW 4-8
is located immediately east of chloroform pumping well MW-4, where chloroform was detected
at a concentration of 1,140 µg/L. Although the plume boundary remained between MW-4 and
TW4-8 from the first quarter of 2005 through the fourth quarter of 2013, TW4-8 was re-
incorporated into the plume between the first quarter of 2014 and the fourth quarter of 2019.
Elevated chloroform at TW4-8 was bounded to the north by TW4-3 and TW4-38 (both 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 (which has remained below 10 µg/L and is non-detect this quarter).
Although previously elevated, TW4-8 remained outside of and bounded the plume during 2020,
and remains outside of and bound the plume this quarter. Changes in the plume boundary near
TW4-8 are expected to result from change in pumping and reduced dilution resulting from
cessation of water delivery to the northern wildlife ponds.
Chloroform at TW4-29 (located at the southeastern extremity of the plume, to the east of TW4-
26 and to the south of TW4-27) increased from 543 µg/L to 602 µg/L; and chloroform at TW4-
30, located immediately cross-gradient of TW4-29, decreased slightly from 78.7 µg/L to 78.2
µg/L, remaining within the plume. Chloroform at TW4-14 remained non-detect and chloroform
at TW4-27 decreased from approximately 4.3µg/L to 3.8 µg/L. Concentration trends at these
wells are generally consistent with ongoing, but slow, downgradient migration of chloroform at
these locations. For example, it took more than 51 quarters for detectable chloroform at TW 4-4
to migrate approximately 400 feet downgradient to TW4-14; and it took more than 30 quarters
27
for chloroform exceeding 70 µg/L at TW4-29 to migrate approximately 160 feet to TW4-30. In
addition, although TW4-30 was previously downgradient of TW4-29, due to long-term changes
in water levels in this area, TW4-30 is now generally cross-gradient of TW4-29.
Furthermore, as discussed in Section 4.1.1, general increases in concentrations 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. Recent increases in concentration at TW4-26 have widened the southeast
extremity of the plume which historically was narrow compared to more upgradient locations.
Chloroform at TW4-29 is bounded to the north by TW4-27 (approximately 3.8 µg/L), to the
southeast by TW4-35 (non-detect), to the south by TW4-34 (non-detect), and to the west-
northwest by TW4-6 (approximately 3.7 µg/L) and TW4-23 (non-detect). As a consequence of
increases in concentration, TW4-30 no longer bounds the plume immediately to the east.
Chloroform at TW4-33 (located between TW4-4 and TW4-29) showed a decrease in
concentration, from approximately 64 µg/L to approximately 60 µg/L. Chloroform at TW4-33 is
bounded to the north by TW4-14 (non-detect), to the east by TW4-27 (approximately 3.8 µg/L),
and to the west by TW4-6 (approximately 3.7 µg/L) and TW4-23 (non-detect).
The chloroform concentration in TW4-6 increased from approximately 3 µg/L to 3.7 µg/L.
TW4-6 has remained outside the chloroform plume since the third quarter of 2018. Installed in
the second quarter of 2000, TW4-6 was the most downgradient temporary perched well prior to
installation of TW4-23 in 2007 and TW4-26 in the second quarter of 2010. TW4-6 remained
outside the chloroform plume between installation in the second quarter of 2000 and the fourth
quarter of 2008 likely 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. TW4-6 was subsequently
incorporated into the plume twice: from the first quarter of 2009 through the third quarter of
2010; and from the third quarter of 2014 through the second quarter of 2018. 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.
The relatively slow rate of chloroform migration in the vicinity of TW4-6 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 TW 4-4 pumping, chloroform concentrations at both TW 4-29 and
TW4-33 have been expected to eventually trend downward; and recent data are consistent with
this expectation.
28
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
contraction near TW4-9; and slight expansion near TW4-24. The chloroform concentration
increase at TW4-24, from approximately 41 µg/L to 103 µg/L, caused slight expansion of the
plume boundary toward the west; and the concentration decrease at TW4-9 (from approximately
102 µg/L to 30 µg/L), caused slight contraction of the plume boundary toward the west. As has
been the case since the first quarter of 2020, due primarily to decreases in concentrations at
TW4-6 and TW4-33, the kriging algorithm has 'pinched off' the southern extremity of the
plume.
TW 4-9 remained outside the plume from the second quarter of 2019 through the first quarter of
2021; was re-incorporated within the plume last quarter; and is again outside the plume this
quarter. TW4-9 was incorporated into the plume from the first quarter of 2016 until the first
quarter of 2019 due to increased concentrations attributable to reduced recharge (and dilution)
from the northern wildlife ponds. Prior to the first quarter of 2016, however, TW4-9 was outside
the plume except during the fomth quarter of 2014.
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 is just within the plume this quarter. TW 4-24
likely remained primarily outside the plume since 2014 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).
Subsequent to the first quarter of 2014, generally higher concentrations at TW4-6 and TW4-16
(both of which were within the chloroform plume in the past) caused the plume boundary to
migrate to the southwest and temporarily re-incorporate both wells. This increase was 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
expected to be influenced by reduced recharge at the southern wildlife pond and the decay of the
associated groundwater mound.
TW 4-6 has remained outside the plume since the third quarter of 2018 due to the general
decrease in chloroform concentrations since the third quarter of 2015, while (as discussed in
Section 4.1.5) TW4-16 has been both within and outside the plume. This quarter, although TW4-
6 remains outside the plume, TW4-16 remains just inside the plume.
The decreasing trend in chloroform concentrations at TW4-6 since the third quarter of 2015, and
generally increased concentrations at TW4-26 since the third quaiter of 2016, suggest that TW4-
4 pumping has arrested chloroform migration between TW 4-4 and TW 4-6, and that increased
chloroform at TW4-26 results from a remnant of the plume that continues to migrate south from
TW4-6 to TW4-26. This behavior is consistent with the apparent 'pinching-off' of the southern
extremity of the plume since the end of 2019. Regardless, pumping at TW4-41, located adjacent
to TW4-4, and pumping at TW4-40, located just south (downgradient) of TW4-26, is expected to
reduce or halt plume expansion to the south.
29
Although the nitrate pumping system may redistribute chloroform within the plume and cause
change. in the chloroform plume boundarie , continued operation of the nitrate pumping sy. Lem
i • expected to enhance capture as ociated with the chloroform pumpjng y tern. Furthermore
since the beginnjng of 2015, the addition of chloroform weJls TW4-l, TW4-2, TW4-ll TW4-
21, TW4-37, TW4-39, TW4-40 and TW4-41 is expected to have a beneficial impact. Generally
reduced concentrations at TW4-6 (since the first quarter of 2015) and TW4-I 6 (since the fourth
quarter of 2014) after previous increa ·es are likely the re uJt of initiation of TW4-l, TW4-2, and
TW4-11 pumping during 2015. Maintaining reduced concentrations at TW4-6 i anticipated to
result from pumping at TW 4-41.
5.0 LONG TERM PUMP TEST AT MW-4, MW-26, TW4-19, TW4-20, AND TW4-4
OPERA TIO NS REPORT
5.1 Introduction
As a part of the inve tigation of chloroform contamination at the MilJ ite EFRI ba been
conducting a Long Term Pump Test on MW-4, TW4-J9, MW-26, and TW4-20, and, si nce
January 31, 2010, TW4-4. The purpo e of tbe te ·t i to erve a an interim action that wrn
remove a significant amount of chloroform-contaminated water while gathering additional data
on hydraulic properties in the area of investigation. TW4-20 collapsed in August of 2020 and
was abandoned in October 2020.
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 welJ TW4-22, TW4-24, and TW4-25 are
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 Jong 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 EFRl began long
term pumping of TW 4-41. Beginning in May 2019 EFRI began long term pumping of TW 4-40.
The following information documents the operational activities during the quarter.
5.2 Pump Test Data Collection
The long term pump te t for MW-4 wa tarted on April 14, 2003, followed by the start of
pumping from TW4-19 on ApriJ 30 2003 from MW-26 on August 8, 2003, from TW4-20 on
Augu t 4, 2005, from TW4-4 on January 31, 2010, and from TW4-22, TW4-24, and TW4-25 on
January 26 2013. Per onnel from Hydro Geo Chem, Inc. were on site to conduct the fi r t pba e
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 discussion 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.
30
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, TW4-21, TWN-2, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39
TW4-40, 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, 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, TW4-11, 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,
TW4-11, TW4-19, TW4-21, TW4-4, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39, TW4-40
(beginning May 2019), 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.
Specific operational problems observed with the well or pumping equipment which occurred
during the quarter are noted for each well below.
31
Unless specifically noted below, no operational problems were observed with the well or
pumping equipment during the quarter.
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 13.4 lb., which is 14 % more than the approximately 11.8 lb.
removed last quarter. The larger rate of mass removal is attributable primarily to the increased
concentrations at TW4-19.
The residual mass of chloroform within the plume is estimated as 933 lb. using the methodology
described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation Method"). This is
approximately 149 lb. larger than last quarter's estimate of 784 lb. 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 933 lb. is substantially lower than both the third quarter 2015
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 is larger 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 and decline. Although the residual mass estimates are generally larger since 2012,
the rate of mass removed per quarter by pumping is also generally larger. Mass removal rates
were particularly enhanced after the addition of 5 new pumping wells in 2015; and the
subsequent addition of 3 additional pumping wells has helped maintain mass removal rates.
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, 2017, 2018, 2019 and 2020 ranged from approximately 84% to 99%. The
approximate proportion of the mass of the plume under capture this quarter is 96%, which is
smaller than last quarter's approximately 99%.

All of the required inspections were completed and the inspection forms are included in Tab C.
5.7 Conditions That May Affect Water Levels in Piezometers

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), except at the location of TW4-30. As discussed in Section 2.4.3, TW4-30 no longer
bounds the plume immediately to the east due to increases in concentration that brought TW4-30
into the plume for the first time during the fourth quarter of 2020. To serve as a new bounding
well, chloroform well TW4-43 was installed to the southeast of TW4-30 during September,
2021. TW4-43 will be sampled during the fourth quarter of 2021.
Although TW4-30 no longer serves as a bounding well, the chloroform plume is bounded to the
north by TW4-25 (non-detect); to the west and southwest by MW-28 (non-detect), MW-31 (non-
detect), MW-32 (non-detect), TW4-6 (approximately 3.7 µg/L) and TW4-23 (non -detect); to Lhe
east by TW4-3 (non-detect), TW4-5 (approximately 11 µg/L), TW4-8 (approximately 17 ~tg/L),
TW4-9 (approximately 30 µg/L) TW4-I3 (non-detecl), TW4-14 (non-detect) TW4-I8
(approximately 50 µg/L), TW4-27 (approximately 3.8 µg/L), TW4-36 (non-detect) and TW4-38
(non-detect); to the south by TW4-34 (non-detect) and TW4-42 (non-detect); and to the
southeast by TW4-35 (non-detect).
Becau e TW4-26 no longer bounded the chloroform plume to lhe south-southwest, TW4-40 was
installed outh (downgradient) of TW4-26 during the first quarter of 2018. Because the econd
quarter of 20J 8 wa the second con ·ecutive quarter that chloroform in TW4-40 exceeded 70
µg/L the required Plan and Time Schedule was submitted and TW4-42 was installed
approximately 200 feel south of TW 4-40 during April, 2019. Chloroform has not been detected
in TW4-42, indicating that TW4-42 bounds the plume immediately to the south-southwest.
Regardless, 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).
33
Except for TW4-30, located in the southeastern extremity of the plume, data collected to date
indicate there are sufficient chloroform monitoring and pumping wells to effectively define
control, and monitor the plume. Subsequent data will determine wh ther or not TW4-30 remain
within the plume and can serve (as in the past) as a bounding well. Regardless of whether or not
TW4-30 remains within the plume, chloroform well TW4-43 has been installed to the southeast
of TW4-30 to serve as a new bounding well; and site water level data indicate that perched
groundwater flow to the east of TW4-30, between TW4-30 and the ea tern site property
boundary, is to the south-southwe ·t; therefore it is unlikely that any chloroform within thi
portion of the plume could ever migrate across the ea tern property boundary. In addition
chloroform in the vicinity of TW4-30 is migrating relatively . lowly; it took more than 30
quarters for chloroform exceeding 70 µg/L at TW4-29 to migrate approximately 160 feet to
TW4-30. Furthermore, hydraulic gradients from TW4-29 to TW4-30 that are now nearly non-
existent as a result of long-term decline is expected to reduce chloroform migration rates in this
area. Finally, the groundwater flow direction in the immediate vicinity of TW4-30 is now
southerly, toward TW4-35 which remains non-detect for chloroform.
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 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 di po ·ed of in the tailings
management system or fed in the Mill pr ce All extracted groundwater was handled as
required by the GCAP.
7 .4 Compliance Well Performance
Part Il.G 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 as noted in
previou reports. The previously noted exceedances have been addressed in Plans and Time
Schedules. There are no new exceedances in Q3 2021.
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 933 lb. using the methodology
described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation Method"). This is
34
approximately 149 lb. more than last quarter's estimate of 784 lb.
The mass of chloroform removed from the plume this quarter by pumping, approximately 13.4
lb., is 14 % greater than the mass removed last quarter (approximately 11.8 lb.). The larger mass
removal is attributable primarily to the increased concentration at TW4-19.
The chloroform plume is entirely contained 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) except at the location of TW4-30. As discussed in Se tion 2.4.3, TW4-30 does not
bound the plume immediately to the east this quarter due to increa. e i11 concentration that
brought TW4-30 into the plume for the first time during the fourth quarter of 2020.
However, chloroform well TW4-43 has been installed to the southeast of TW4-30 to serve as a
new bounding well; and the plume is currently bounded to the north by TW4-25 (non-detect); to
the west and southwest by MW-28 (non-detect), MW-31 (non-detect) MW-32 (non-detect),
TW4-6 (approximately 3.7 µg/L) and TW4-23 (non-detect); to the ea t by TW4-3 (non-detect)
TW4-5 (approximately 11 µg/L), TW4-8 (approximately 17 ~tg/L) TW4-9 (approX_irnately 30
µg/L), TW4-13 (non-detect) TW4-14 (non-detect), TW4-J8 (approximately 50 µg/L), TW4-27
(approximately 3.8 µ.g/L), TW4-36 (non-detect) and TW4-38 (non-detect)· to the outh by TW4-
34 (non-detect) and TW4-42 (non-detect); and to the southeast by TW4-35 (non-detect).
Becau e TW4-26 no longer bounded the chloroform plume to the south-outhwest TW4-40 wa
in stalled sooth (downgradient) of TW4-26 during the fir 't quarter of 2018. Becau e the econd
quarter of 2018 wa the econd con ecutive quarter that chloroform in TW4-40 exceeded 70
µg/L the required Plan and Time Schedule wa ubmitted and TW4-42 was in tailed
approximately 200 feet outb of TW4-40 during April, 2019. Chloroform ha not been detected
in TW4-42, indicating that TW4-42 bound the plume immediately to the south-outhwe t.
RegardJe ·s 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 oath (cro s-to downgradienr).
Except for TW4-30, located in the southeastern extremity of the plume, data collected to date
indicate there are sufficient chloroform monitoring and pumping well to effectjvely define
control, and monitor the plume. Subsequent data will determine whether or not TW4-30 remains
within the plume and can serve (as in the past) as a bounding well. Regardless of whether or not
TW 4-30 remains within the plume, chloroform well TW 4-43 has been installed to the southeast
of TW 4-30 to serve as a new bounding well; and site water level data indicate that perched
groundwater flow to the east of TW4-30, between TW4-30 and the ea tern site property
boundary, is to the south-southwe t; therefore it is unlikely that any chloroform within thi
portion of the plume could ever migrate across the eastern property boundary. In addition,
chloroform in the vicinity of TW4-30 is migrating relatively lowly; it took more than 30
quarters for chloroform exceeding 70 µg/L at TW4-29 to migrate approximately 160 feet to
TW4-30. Furthermore, hydraulic gradients from TW4-29 to TW4-30 that are now nearly non-
existent as a result of long-term decline is expected to reduce chloroform migration rates in this
area. Finally, the groundwater flow direction in the vicinity of TW4-30 is now southerly, toward
TW4-35, which remains non-detect for chloroform.
35
The water level contour maps for the third quarter, 2021 indicate effective capture of water
containing high chloroform concentrations over most of the chloroform plume. Capture in the
southeastern portion of the plume (vicinity of MW-4) was enhanced by start-up of chloroform
pumping wells TW4-1, TW4-2, and TW4-11 during the first quarter of 2015. Capture in the
northwestern portion of the plume was enhanced by start-up of chloroform pumping wells TW4-
21 and TW4-37 during the second quarter of 2015; and of TW4-39 during the fourth quarter of
2016. Capture in the southernmost portion of the plume was enhanced by ta11-up of pumping at
TW4-41 during the second quarter of 2018 and of TW4-40 during the second quarter of 2019.
All pumping wells added since the beginning of 2015 have enhanced the effectiveness of
chloroform mass removal.
Although pumping began in the first quarter of 2010, a well-defined capture zone was not clearly
evident at chloroform pumping well TW 4-4 until the third quarter of 2018. Increased draw downs
in this area since the second quarter of 2018, and development of a definable capture zone, is
attributable to pumping at adjacent well TW4-41.
The capture zone ass ociated with TW4-4 was likely ob cured prior to the second quarter of 2018
by the historically relatively low water level at adjacent well TW4-14 and the two orders of
magnitude decrease in permeability south of TW 4-4. However, as noted in previous reports,
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 TW 4-4 pumping.
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 smaller than last quarter, with capture decrea ing within the central and northern
portions of the combined pumping system due primarily to decreased drawdowns at MW-26 and
TWN-2.
'Background' flow through the chloroform plume was calculated as approximately 3.4 gpm (See
HGC March 31, 2016: Corrective Action Comprehensive Moni toring Evaluation [CACME]
Report White Me ·a Uranium Mill Near Blanding, Utah). Pumping from wells within and
immediately adjacent to the chloroform plume during the current quarter (from well · MW-4
MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-21, TW4-22, TW4-24, TW4-37,
TW4-39, TW4-40 and TW4-41) is approximately 4.9 gpm. The combined pumping rate of 4.9
gpm exceeds the calculated background flow by 1.5 gpm or 44%, 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. Wells MW-26, TW4-6, TW4-8, TW4-9, TW4-11,
TW4-19, TW4-21, TW4-22, TW4-24, TW4-37 and TW4-39 had changes in concentration
greater than 20%. Of these, MW-26, TW4-11, TW4-19, TW4-21, TW4-37 and TW4-39 are
chloroform pumping wells; and TW4-22 and TW4-24 are nitrate pumping wells. TW4-6 is
36
located adjacent to chloroform pumping wells TW4-4 and TW4-41; TW4-8 is located adjacent to
chloroform pumping well MW-4; and TW4-9 is located near chloroform pumping well TW4-39.
Fluctuations in concentrations at both chloroform and nitrate pumping wells and wells adjacent
to pumping wells likely result in part from changes in pumping. In addition, fluctuations in
concentrations at wells such as TW 4-9 are expected based on their location near the plume
margins. Furthermore, changes in concentrations at chloroform wells are expected to result from
continued operation of the nitrate pumping system, as the capture associated with nitrate
pumping expands and flow directions change locally.
Chloroform pumping well s MW-26 (1,580 µg/L); TW4-2 (1150 µg/L), TW4-J I (2,600 µg/L);
TW4-19 (4,450 µg/L); TW4-37 (10,200 µg/L)· and nitrate pumping well TW4-22 (3 510 µg/L)
had the highest detected chloroform concentrations. Although pumping well TW4-20 formerly
located between pumping wells TW4-19 and TW4-37, would typically be distinguished as
having one of the highest concentrations, TW4-20 collapsed during August, 2020 and was
abandoned in October, 2020.
Since last quarter, the chloroform concentrations in MW-26 increased from 998 to 1,580 µg/L;
TW4-2 decreased from 1,160 to 1,150 µg/L; TW4-l 1 decreased from 3,320 to 2,600 µg/L; TW4-
19 increased from 775 to 4,450 µg/L; and TW4-37 decreased from 13,000 to 10,200 µg/L. In
addition, the chloroform concentration in chloroform pumping well TW4-21 decreased from
1,130 to 669 µg/L; the concentration in nitrate pumping well TW4-22 decrea ed from 4,520 to
3,510 µg/L; and the concentration in nit.rate pumping well TW4-24 increa. ed from 41.2 to 103
µg/L, taking it just within the plume boundary tl1is quarter. 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 fir t quarter of 2008 through the fourth
quarter of 2013) decreased from 22.3 µg/L to 17 µg/L and remained outside the plume. TW4-8
is located immediately east of chloroform pumping well MW-4, where chloroform wa. detected
at a concentration of 1,140 µg/L. Although the plume boundary remained between MW-4 and
TW4-8 from the first quarter of 2005 through the fourth quarter of 2013 TW4-8 was re-
incorporated into the plume between the first quarter of 2014 and the fourth quarter of 2019.
Elevated chloroform at TW4-8 was bounded to the north by TW4-3 and TW4-38 (both non-
detect), to the northeast by TW 4-13 (non-detect), to the east by TW 4-36 (non-detect), and to the
southeast by TW4-14 (which has remained below 10 µg/L and is non-detect this quarter).
Although previously elevated, TW4-8 has remained outside of and has bounded the plume since
the end of 2019. 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.
Detectable chloroform concentration at TW 4-14 (between the fourth quarter of 2014 and the
fir t quarter of 2021) and at TW4-27 ( ince 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 remained non-detect and chloroform at TW4-27 decreased
37
from approximately 4.3 µg/L to 3.8 µg/L. Pumping at TW4-41 is expected to reduce or prevent
future migration of chloroform toward these wells.
Concentration trends at TW4-29 (located at the southeastern extremity of the plume, to the east
of TW4-26 and to the south of TW4-27); and at TW4-30 (located immediately east of TW4-29),
are also generally consistent with ongoing, but slow, downgradient migration of chloroform.
Although previously downgradient of TW4-29, due to long-term changes in water levels in this
area, TW4-30 is now generally cross-gradient of TW4-29. Chloroform at TW4-29 increased
from 543 µg/L to 602 µg/L; and chloroform at TW4-30 decreased slightly from 78.7 µg/L to
78.2 µg/L, remaining within the plume. As discussed above, slow downgradient migration is
consistent with the more than 30 quarters needed for chloroform exceeding 70 µg/L at TW4-29
to migrate approximately 160 feet to TW4-30.
Chloroform at TW4-29 is bounded to the north by TW4-27 (approximately 3.8 µg/L), to the
southeast by TW4-35 (non-detect), to the south by TW4-34 (non-detect), and to the west-
northwest by TW4-6 (approximately 3.7 µg/L) and TW4-23 (non-detect). As discussed above,
TW4-30 no longer bounds the plume immediately to the east. In addition, general increases in
concentrations at TW4-26 since the third quarter of 2016 are 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 slight decrease in
concentration, from approximately 64 µg/L to approximately 60 µg/L. Chloroform at TW4-33 is
bounded to the north by TW4-14 (non-detect), to the east by TW4-27 (approximately 3.8 µg/L),
and to the west by TW4-6 (approximately 3.7 µg/L) and TW4-23 (non-detect).
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 light
expansion near TW4-24; and slight contraction near TW4-9. The chloroform concentration
increase at TW4-24, from approximately 41 µg/L to 103 µg/L, caused slight expansion of the
plume boundary toward the west; and the concentration decrease at TW4-9 (from approximately
102 µg/L to 30 µg/L), caused slight contraction of the plume boundary toward the west. As has
been the case since the first quarter of 2020, due primarily to decrea es in concentrations at
TW4-6 and TW4-33, the kriging algorithm ha 'pinched off' the outhern. extremity of the
plume.
TW4-9 remained out ide the pJume from the econd quarter of 2019 through the fir t quarter of
2021; was re-incorporated within the plume lasl quarter; and i again outside the plume thi
quarter. TW4-9 wa incorporated into the plume from the first quarter of 2016 until the first
quarter of 2019 due to increa ·ed concentrations attributable to reduced recharge (and dilution)
from the northern wildlife ponds. However, except for the fourth quarter of 2014, TW4-9 was
outside the plume prior to the first quarter of 2016. TW4-38 was installed to the east-southeast of
TW4-9 to serve as a bounding well when concentrations at TW4-9 exceeded 70 µg/L.
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-
38
24 has been both inside and outside the plume and is again just within the plume this quarter.
TW4-24 likely remained primarily outside the plume since 2014 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). Subsequent to the first quarter of 2014, generally increased concentrations at
TW4-6 and TW4-16 (both of which were within the chloroform plume in the past), caused the
plume boundary to migrate to the southwest and temporarily re-incorporate both wells. Increased
concentrations at these wells subsequent to the first 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 are expected to be influenced
by reduced recharge at the southern wildlife pond and the decay of the associated groundwater
mound.
Since 2014, TW4-16 has been both within and outside the plume; whereas a decreasing trend in
chloroform concentrations at TW4-6 (since the third quarter of 2015) has once again taken TW4-
6 outside the plume. This quarter, TW4-16 and TW4-6 remain within and outside the plume,
respectively. Although chloroform at TW4-16 has been above and below 70 µg/L since 2014,
and was detected at 202 µg/L this quarter, concentrations have generally increased since 2018,
likely in response to reduced dilution.
The decreasing trend in chloroform concentration at TW4-6 since the third quarter of 2015, and
generally increased 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 the increased
chloroform at TW4-26 results from a remnant of the plume that continues to migrate south
toward TW4-26. Pumping at adjacent well TW4-41 since the second quarter of 2018 has likely
enhanced the decline in TW4-6 concentrations to less than 70 µg/L.
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 pumping wells TW4-1, TW4-2, TW4-11, TW4-21, TW4-37, TW4-39,
TW 4-40 and TW 4-41 since the beginning of 2015 is expected to have a beneficial impact.
Generally reduced concentrations at TW4-6 (since the third quarter of 2015) and TW4-16 (since
the fourth quarter of 2014) after previous increases are likely the result of initiation of TW4-1,
TW 4-2, and TW 4-11 pumping.
Continued operation of the original chloroform pumping wells (MW-4, MW-26, and TW 4-19) 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 aUowing natural attenuation to be
more effective.
Continued operation of chloroform pumping well TW 4-4, augmented by pumping at adjacent
well TW 4-41, 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 TW 4-4. The decrease in the long-term rate of water level rise at TW 4-6 once
39
TW4-4 pumping began, which suggests that TW4-6 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 concentration since the first
quarter of 2015 at TW4-6 are also attributable in part to TW4-4 (augmented by TW4-41)
pumping.
Continued operation of chloroform pumping wells TW4-1, TW4-2, TW4-1 l, TW4-21, TW4-37,
TW4-39, TW4-40 and TW4-41 is also recommended because pumping these wells has increased
overall capture and improved chloroform mass removal. In particular, continued pumping of
TW 4-37 (in conjunction with TW 4-19) is expected to at least partially compensate for the loss of
TW4-20; and pumping at TW4-40 has expanded capture within the southern extremity of the
plume.
Furthermore, because of the influence of TW4-4 pumping (augmented by TW4-41 pumping
since the second quarter of 2018), and by analogy with the concentration decrease. at TW4-6 and
TW4-26 that occurred after initiation of TW4-4 pumping, chloroform concentration at TW4-29
and TW4-33 were expected to eventually trend downward. Since the third quarter of 2014, TW4-
33 concentrations that have been relatively stable to decreasing; and TW4-29 concentrations that
generally increased before becoming stable to decrea ing; appear con i tent with the e
expectations. As discussed above. trends at the e well sugge t that chloroform migration ha
been arrested at TW4-33 by TW4-4 (and TW4-41) pumping and that previou ly increa ing
chloroform at downgradient well TW4-29 resulted from a remnant of the plume that migrated
past TW4-33 generally toward TW4-30, which until recently was downgradient of TW4-29, and
which until the fourth quarter of 2020 bounded the 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 TW 4-29
and TW4-33. Pumping at adjacent well TW4-41 is likely to help maintain or enhance these
decrea ing trends in water levels and to augment tbe expected eventual reductions in
concentrations in the distal end of the plume. 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 as ociated with cessation of
water delivery to the northern wildlife ponds in March, 2012 during discussions with DWMRC
in March 2012 and May 2013. While pa t 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 has caused the expected decrease in hydraulic
gradients and the increases in constituent concentrations within the chloroform plume. Generally
increased chloroform concentrations at TW4-6 (between 2013 and 2020)· and at TW4-8, TW4-9
and TW4-16 (since 2013), are likely related in part to reduced dilution (although concentration
at TW4-6 and TW4-8 have been trending downward since the first qua1ter of 2015; and
concentrations at TW4-9 have been trending generally downward since the fir. t quarter of 2018).
As discussed above, increased concentrations 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.
40
The net impact of reduced wildlife pond recharge i expected to be beneficial even though it is
al o expected to re ult in higher concentrations that will per i t until continued ma reduction
via pumping and natural attenuation ultimately reduce concentration . Temporary increa e in
chloroform concentrations are judged le s important than reduced chloroform migration rates.
The evolution of the impacts of reduced recharge on concentrations and plume migration rates
will be defined by continued monitoring.

RE: 3rd Quarter Chloroform 2021
Dear Tanner Holliday: Lab Set ID: 2108726
American West Analytical Laboratories received sample( s) on 8/26/2021 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,

RE: 3rd Quarter Chloroform 2021
Dear Tanner Holliday: Lab Set ID: 2109449
American West Analytical Laboratories received sample( s) on 9/17/2021 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,

RE: 3rd Quarter Chloroform 2021
Dear Tanner Holliday: Lab Set ID: 2109638
American West Analytical Laboratories received sample(s) on 9/24/2021 for the analyses
presented in the following report.
American West Analytical Laboratories (AW AL) 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,

NM = Not Measured. The OAP does not require the measurement of redox potential or turbidity in wells that were purged to dryness.
RPO = Relative Percent Difference
The OAP 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 OAP does not require that turbidity measurements be less than 5 NTU prior to
sampling. As such, the noted observations regarding turbidity measurements Jess than 5 NTU are included for information purposes only.
