1.0 INTRODUCTION
The presence of chloroform was initially identified in groundwater at the White Mesa Mill (the
"Mill") as a result of split sampling performed in May 1999. The discovery resulted in the
issuance of State of Utah Notice of Violation ("NOV") and Groundwater Corrective Action
Order ("CAO") State of Utah Department of Environmental Quality ("UDEQ"), Division of
Waste Management and Radiation Control ("DWMRC") Docket No. UGW-20-01, which
required that Energy Fuels Resources (USA) Inc. ("EFRI") submit a Contamination Investigation
Plan and Report pursuant to the provisions of UAC R317-6-6.15(D). In response to the NOV,
EFRI submitted a series of documents outlining plans for investigation of the chloroform
contamination. This plan of action and preliminary schedule was set out in EFRI submittals
dated: September 20, 1999; June 30, 2000; April 14, 2005; and November 29, 2006. EFRI
submitted a draft Groundwater Corrective Action Plan ("GCAP") dated August 22, 2007. The
draft GCAP was reviewed by the Director, who advised EFRI in 2013 that modifications were
required. In an effort to expedite and formalize active and continued remediation of the
chloroform plume, both parties have agreed to the GCAP found in Attachment 1, of the final
Stipulation and Consent Order ("SCO") dated September 14, 2015.
This is the Quarterly Chloroform Monitoring Report for the second quarter of 2016 as required
under the SCO. This report also includes the Operations Report for MW-04, TW4-01, TW4-04,
TW4-02, TW4-11, TW4-19, TW4-20, TW4-21, MW-26, TW4-22, TW4-24, TW4-25, and TW4-
37 for the quarter.
2.0 CHLOROFORM MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing wells,
temporary chloroform contaminant investigation wells and temporary nitrate investigation wells
is attached under Tab A. Chloroform samples and measurements taken during this reporting
period are discussed in the remainder of this section.
2.1.1 Chloroform Monitoring
Quarterly sampling for chloroform monitoring parameters is currently required in the following
wells:
MW-4 TW4-9 TW4-18 TW4-27 TW4-36
TW4-1 TW4-10 TW4-19 TW4-28 TW4-37
TW4-2 TW4-11 TW4-20 TW4-29
TW4-3 TW4-12 TW4-21 TW4-30
TW4-4 TW4-13 TW4-22 TW4-31
TW4-5 TW4-14 TW4-23 TW4-32
TW4-6 MW-26 (formerly TW4-15) TW4-24 TW4-33
TW4-7 TW4-16 TW4-25 TW4-34
TW4-8 MW-32 (formerly TW4-17) TW4-26 TW4-35

Chloroform monitoring was performed in all of the required chloroform monitoring wells. Table
1 provides an overview of all wells sampled during the quarter, along with the date samples were
collected from each well, and the date(s) when analytical data were received from the contract
laboratory. Table 1 also identifies equipment rinsate samples collected, as well as sample
numbers associated with the deionized field blank ("DIFB") and any required duplicates.
2.1.2 Parameters Analyzed
Wells sampled during this reporting period were analyzed for the following constituents:
• Chloroform
• Chloromethane
• Carbon tetrachloride
• Methylene chloride
• Chloride
• Nitrate plus Nitrite as Nitrogen
Use of analytical methods is consistent with the requirements of the Chloroform Investigation
Monitoring Quality Assurance Program (the "Chloroform QAP") attached as Appendix A to the
White Mesa Uranium Mill Groundwater Monitoring QAP Revision 7.2, dated June 7, 2012.
2.1.3 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant to Part
I.E.3 of the Groundwater Discharge Permit (the "GWDP"):
• The quarterly groundwater compliance monitoring wells
• Existing monitoring well MW -4 and all of the temporary chloroform investigation wells
• Piezometers P-1, P-2, P-3, P-4 and P-5
• MW-20 and MW-22
• Nitrate monitoring wells
• The DR piezometers that were installed during the Southwest Hydrologic Investigation
In addition to the above, depth to water measurements are routinely observed in conjunction with
sampling events for all wells sampled during quarterly and accelerated efforts, regardless of the
sampling purpose.
Weekly and monthly depth to groundwater measurements were taken in the chloroform
pumping wells MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21,
TW4-37, 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. The revised Groundwater QAP and Chloroform QAP, Revision
7.2 were approved by DWMRC on June 7, 2012.
The sampling methodology, equipment and decontamination procedures used in the chloroform
contaminant investigation, as summarized below, are consistent with the approved QAP
Revision 7.2 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 Dl water prior to each calibration.
The non-dedicated purging pump is decontaminated after each use and prior to use at subsequent
sampling locations using the following procedures:
a) the pump is submerged into a 55-gallon drum of nonphosphate detergent/DI water mixture;
b) the detergent/DI water solution is pumped through the pump and pump outlet lines into the
drain line connected to Cell 1;
c) the pump is submerged into a 55-gallon drum of DI water;
d) the DI water solution is pumped through the pump and pump outlet lines into the drain line
connected to Cell 1;

2.2.2 Well Purging and Depth to Groundwater
The non-pumping wells are purged prior to sampling by means of a portable pump. A list of the
wells in order of increasing chloroform concentration is generated quarterly. The order for
purging the non-pumping wells is thus established. The list is included with the Field Data
Worksheets under Tab B. Mill personnel start purging with all of the non-detect wells and then
move to the wells with detectable chloroform concentrations staring with the lowest
concentration and proceeding to the wells with the highest concentration. One deviation to this
practice is made for the continuously pumping wells. These wells are sampled throughout the
sampling event and are not sampled in the order of contamination. This practice does not affect
the samples for this reason: the pumping wells have dedicated pumps and there will be no cross-
contamination resulting from the sampling order.
Samples are collected by means of disposable bailer(s) the day following the purging. The
disposable bailer is used only for the collection of a sample from an individual well and disposed
subsequent to the sampling. As noted in the approved QAP, Revision 7 .2, sampling will
generally follow the same order as purging; however; the sampling order may deviate slightly
from the generated list. This practice does not affect the samples for these reasons: any wells
sampled in slightly different order either have dedicated pumps or are sampled via a disposable
bailer. This practice does not affect the quality or usability of the data as there will be no cross-
contamination resulting from the sampling order.
Before leaving the Mill office, the portable pump and hose are rinsed with DI water. Where
portable (non-dedicated) sampling equipment is used, a rinsate sample is collected at a frequency
of one rinsate sample per 20 field samples. Well depth measurements are taken and the one
casing volume is calculated for those wells which do not have a dedicated pump as described in
Attachment 2-3 of the QAP. Purging is completed to remove stagnant water from the casing and
to assure that representative samples of formation water are collected for analysis. There are
three purging strategies that are used to remove stagnant water from the casing during
groundwater sampling at the Mill. The three strategies are as follows:
1. Purging three well casing volumes with a single measurement of field parameters
specific conductivity, turbidity, pH, redox potential, and water temperature
2. Purging two casing volumes with stable field parameters for specific conductivity,
turbidity, pH, redox potential, and water temperature (within 10% Relative Percent
Difference ["RPD"])
3. Purging a well to dryness and stability (within 10% RPD) of field parameters for pH,
specific conductivity, and water temperature only after recovery
If the well has a dedicated pump, it is pumped on a set schedule per the remediation plan and is
considered sufficiently evacuated to immediately collect a sample; however, if a pumping well
has been out of service for 48 hours or more, EFRI will follow the purging requirements outlined
in Attachment 2-3 of the QAP. The dedicated pump is used to collect parameters and to collect
the samples as described below. If the well does not have a dedicated pump, a Grundfos pump
4
(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 bailers.
Mill personnel use a disposable bailer to sample each well that does not have a dedicated pump.
The bailer is attached to a reel of approximately 150 feet of nylon rope and then lowered into the
well. After coming into contact with the water, the bailer is allowed to sink into the water in
order to fill. Once full, the bailer is reeled up out of the well and the sample bottles are filled as
follows:
• Volatile Organic Compound ("VOC") samples are collected first. This sample consists
of three 40 ml vials provided by the Analytical Laboratory. The VOC sample is not
filtered and is preserved with HCl;
• A sample for nitrate/nitrite is then collected. This sample consists of one 250 ml. bottle
that is provided by the Analytical Laboratory. The nitrate/nitrite sample is not filtered
and is preserved with H2S04;
• A sample for chloride is then collected. This sample consists of one 500 ml. bottle that is
provided by the Analytical Laboratory. The chloride sample is not filtered and is not
chemically preserved.
After the samples have been collected for a particular well, the bailer is disposed of and the
samples are placed into the cooler that contains ice. The well is then recapped and Mill personnel
proceed to the next well.

2.3 Field Data
Attached under Tab B are copies of the Field Data Worksheets that were completed during the
quarter for the chloroform contaminant investigation monitoring wells identified in paragraph
2.1.1 above, and Table 1.
2.4 Depth to Groundwater Data and Water Table Contour Map
Attached under Tab C are copies of the Depth to Water Sheets for the weekly monitoring of
MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22, TW4-
24, TW4-25, TW4-37, and TWN-2 as well as the monthly depth to groundwater data for the
chloroform contaminant investigation wells and the non-pumped wells measured during the
quarter. Depth to groundwater measurements that were utilized for groundwater contours are
included on the Quarterly Depth to Water Worksheet at Tab D of this report, along with the
kriged groundwater contour map for the current quarter generated from this data. A copy of the
kriged groundwater contour map generated from the previous quarter's data is provided under
Tab E.
2.5 Laboratory Results
2.5.1 Copy of Laboratory Results
All analytical results were provided by American West Analytical Laboratory ("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 thirteen 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, two duplicate samples were collected as indicated in Table 1. The duplicates
were sent blind to the analytical laboratory and analyzed for the same parameters as the
chloroform wells.
Two trip blanks were provided by A W AL and returned with the quarterly chloroform monitoring
samples.
Two rinsate blank samples were collected at a frequency of one rinsate per twenty samples per
QAP Section 4.3.2 and as indicated on Table 1. Rinsate samples were labeled with the name of
the subsequently purged well with a terminal letter "R" added (e.g. 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
QAJQC evaluation of sample duplicates, a QC Control Limit check for analyses and blanks
including the DIFB and a rinsate sample check. Each evaluation is discussed in the following
sections. Data check tables indicating the results of each test are provided under Tab I.
3.4.1 Field Data QA/QC Evaluation
The QA Manager performs a review of the field recorded parameters to assess their adherence
with QAP requirements. The assessment involved review of two sources of information: the
Field Data Sheets and the Quarterly Depth to Water summary sheet. Review of the Field Data
Sheets addresses well purging volumes and measurement of field parameters based on the
requirements discussed in section 2.2.1 above. The purging technique employed determines the
requirements for field parameter measurement and whether stability criteria are applied. Review
of the Depth to Water data confirms that all depth measurements used for development of the
groundwater contour maps were conducted within a five-day period as indicated by the
measurement dates in the summary sheet under Tab D. The results of this quarter's review of
field data are provided under Tab I.
Based upon the review of the field data sheets, the purging and field measurements were
completed in conformance with the QAP requirements. A summary of the purging techniques
employed and field measurements taken is described below:
Purging Two Casing Volumes with Stable Field Parameters (within 10% RPD)
Wells TW4-3, TW4-5, TW4-7, TW4-8, TW4-9, TW4-12, TW4-16, MW-32, TW4-18, TW4-23,
TW4-28, and TW4-32 were sampled after two casing volumes were removed. Field parameters
(pH, specific conductivity, turbidity, water temperature, and redox potential) were measured
during purging. All field parameters for this requirement were stable within 10% RPD.
Purging a Well to Drynes and Stability of a Limited List of Field Parameters
Wells TW4-6, TW4-10, TW4-13, TW4-14, TW4-26, TW4-27, TW4-29, TW4-30, TW4-31,
TW4-33, TW4-34, TW4-35, and TW4-36 were pumped to dryness before two casing volumes
were evacuated. After well recovery, one set of measurements of pH, conductivity and
temperature were taken. The samples were then collected, and another set of measurements of
pH, conductivity and temperature were taken. Stabilization of pH, conductivity and temperature
are required within 10% RPD under the QAP, Revision 7.2. The QAP requirements for
stabilization were met.
Continuou ly Pumped Wells
Wells MW-4, TW4-1, TW4-2, TW4-4, TW4-11, MW-26, TW4-19, TW4-20, TW4-21, TW4-22,
TW4-24, TW4-25, and TW4-37 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, Revision 7.2 requirements resulted in
the observations noted below. The QAP requirements in Attachment 2-3 specifically state that
field parameters must be stabilized to within 10% over at least 2 consecutive measurements 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 TW4-4, TW4-5, TW4-7, TW4-9, TW4-12, TW4-16, MW-32, TW4-18, TW4-23, TW4-28,
and TW4-32 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
9
interference and/or sample dilution. In these cases, the reported value for the analyte was higher
than the increased detection limit.
3.4.6 Receipt pH Evaluation
Appendix A of the QAP states that volatile samples are required to be preserved and arrive at the
laboratory with a pH less than 2. A review of the laboratory data revealed that the volatile
samples were received at the laboratory with a pH less than 2.
3.4. 7 Trip Blank Evaluation
Trip blank results were reviewed to identify any VOC contamination resulting from transport of
the samples. Trip blank checks are provided in Tab I. The trip blank results were less than the
reporting limit for all VOCs.
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 except for the nitrate result in
the duplicate pair TW4-12/TW4-65. Duplicate results are provided under Tab I. The approved
QAP specifies a separate corrective action for duplicate RPDs outside of acceptance limits. The
revised procedure for duplicate results outside of acceptance limits was implemented during the
quarter for the results in duplicate pair TW4-12/TW4-65. The corrective actions that were taken
in accordance with the QAP procedure are as follows: the QA Manager contacted the Analytical
Laboratory and requested a review of the raw data to assure that there were no transcription
errors and the data were accurate} y reported. The laboratory noted that the data were accurate
and reported correctly. Reanalysis was not completed as the samples were beyond the holding
time.
3.4.9 Rinsate Sample Check
Rinsate blank sample checks are provided in Tab I. The rinsate blank sample concentration
levels were compared to the QAP requirements i.e., that rinsate sample concentrations be one
order of magnitude lower than that of the actual well. The rinsate blank sample results were
nondetect for this quarter.
10
While not required by the Chloroform QAP, DIFB samples are collected to analyze the quality of
the DI water system at the Mill, which is also used to collect rinsate samples. A review of the
analytical results reported for the DIFB sample indicated the sample results were nondetect.
3.4.10 Other Laboratory QA/QC
Section 9.2 of the QAP requires that the laboratory's QA/QC Manager check the following items
in developing data reports: (1) sample preparation information is correct and complete, (2)
analysis information is correct and complete, (3) appropriate analytical laboratory procedures are
followed, (4) analytical results are correct and complete, (5) QC samples are within established
control limits, (6) blanks are within QC limits, (7) special sample preparation and analytical
requirements have been met, and (8) documentation is complete. In addition to other laboratory
checks described above, EFRI's QA Manager rechecks QC samples and blanks (items (5) and
(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.
The QAP specifies that surrogate compounds shall be employed for all organic analyses, but the
QAP does not specify acceptance limits for surrogate recoveries. The analytical data associated
with the routine quarterly sampling met the requirement specified in the QAP. The information
from the Laboratory QA/QC Summary Reports indicates that the surrogate recoveries for the
quarterly chloroform samples were within acceptable laboratory limits for the surrogate
compounds. The requirement in the QAP to analyze surrogate compounds was met and the data
are compliant with the QAP. Furthermore, there are no QAP requirements for surrogate
recoveries.
The information from the Laboratory QA/QC Summary Reports indicates that the Laboratory
Control Samples (the "LCS") recoveries were within acceptable laboratory limits for the LCS
compounds except as noted below.
The information from the Laboratory QA/QC Summary Reports indicates that the LCS
11
recoveries for the samples were within acceptable laboratory limits for the regulated compounds
except as indicated in Tab I. The data recoveries (methylene chloride) were above the laboratory
established acceptance limits do not affect the quality or usability of the data because the
recoveries above the acceptance limits indicate a potential high bias to the sample results.
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 wildlife ponds
disrupts the generally southwesterly flow pattern, to the extent that locally northerly flow occurs
near 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 mound decays due to reduced recharge.
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 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 during discussions 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.
12
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 wildlife ponds.
Localized increases in concentrations of constituents such as chloroform and nitrate within and
near the chloroform plume, and of nitrate and chloride within and near the nitrate plume, may
occur even when these plumes are under control. Ongoing mechanisms that can be expected to
increase constituent concentrations locally as a result of reduced wildlife pond recharge include
but are not limited to:
1) Reduced dilution -the 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 recetvmg
primarily low constituent concentration pond water will result in wells intercepting these
layers receiving a smaller proportion of the low constituent concentration water.
The combined impact of the above two mechanisms was anticipated to be more evident at
chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20; nitrate pumping
wells TW4-22, TW4-24, TW4-25, and TWN-2; and non-pumped wells adjacent to the pumped
wells. Impacts were also expected to occur over time at wells added to the chloroform pumping
network during the first quarter of 2015 (TW4-1, TW4-2, TW4-11), and to those added during
the second quarter of 2015 (TW4-21 and TW4-37). The overall impact was expected to be
generally higher constituent concentrations in these wells over time until mass reduction
resulting from pumping and natural attenuation eventually reduces concentrations. Short-term
changes in concentrations at pumping wells and wells adjacent to pumping wells are also
expected to result from changes in pumping conditions.
In addition to changes in the flow regime caused by wildlife pond recharge, perched flow
directions are locally influenced by operation of the chloroform and nitrate pumping wells. Well
defined cones of depression are evident in the vicinity of all chloroform pumping wells except
TW4-4, which began pumping in the first quarter of 2010, and TW4-37, which began pumping
during the second quarter of 2015. Although operation of chloroform pumping well TW4-4 has
depressed the water table in the vicinity of TW 4-4, a well-defined cone of depression is not
clearly evident. The lack of a well-defined cone of depression near TW4-4 likely results from 1)
variable permeability conditions in the vicinity of TW4-4, and 2) persistent relatively low water
levels at adjacent well TW4-14. The lack of a well-defined cone of depression near TW4-37
likely results from recent start-up and close proximity to other pumping wells.
Nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 started pumping during the first
quarter of 2013. Water level patterns near these wells are expected to be influenced by the
presence of, and the decay of, the groundwater mound associated with the northern wildlife
ponds, and by the persistently low water level elevation at TWN-7. By the fourth quarter of
2013, operation of the nitrate pumping system had produced well-defined impacts on water
13
levels. The long-term interaction between the nitrate and chloroform pumping systems is
evolving, and changes will be reflected in data collected as part of routine monitoring.
As discussed above, variable permeability conditions likely contribute to the lack of a well-
defined cone of depression near chloroform pumping well TW 4-4. Changes in water levels at
wells immediately south and southeast (downgradient) of TW4-4 resulting from TW4-4 pumping
are expected to be muted because 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 and TW4-26, and relatively recently
installed wells 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 TW 4-4. Detecting water level draw downs in wells
immediately south and southeast of TW4-4 resulting from TW4-4 pumping has also been
complicated by the general, long-term increase in water levels in this area attributable to past
wildlife pond recharge.
Between the fourth quarter of 2007 and the fourth quarter of 2009 Gust prior to the start of TW 4-
4 pumping), water levels at TW4-4 and TW4-6 increased by nearly 2.7 and 2.9 feet at rates of
approximately 1.2 feet/year and 1.3 feet/year, respectively. However, the rate of increase in
water levels at TW4-6 after the start of pumping at TW4-4 (first quarter of 2010) was reduced to
less than 0.5 feet/year suggesting that TW 4-6 is within the hydraulic influence of TW 4-4.
Since the fourth quarter of 2013, water levels in all wells currently within the chloroform plume
south ofTW4-4 (TW4-6, TW4-29, and TW4-33) have been trending downward. This downward
trend is attributable to the cessation of water delivery to the northern wildlife ponds and
pumping. However, water level trends have been upward in many wells located at the margin of
the chloroform plume southeast of TW4-4 (TW4-14, TW4-27, TW4-30, and TW4-31). These
wells appear as yet to be responding to past wildlife pond recharge and expansion of the
groundwater mound.
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 lack of a well-defined cone of depression at TW4-4 is also influenced by the persistent,
relatively low water level at non-pumping well TW4-14, located east of TW4-4 and TW4-6. For
the current quarter, the water level at TW4-14 (approximately 5533.2 feet above mean sea level
["ft amsl"]), is nearly 3 feet lower than the water level at TW 4-6 (approximately 5536.1 ft amsl)
and approximately 6 feet lower than the water level at TW4-4 (approximately 5539.5 ft amsl),
even though TW 4-4 is pumping. However, water level differences among these wells are
diminishing.
14
The static water levels at wells TW4-14 and downgradient well TW4-27 (installed south of
TW4-14 in the fourth quarter of 2011) were similar (within 1 to 2 feet) until the third quarter of
2014; both appeared anomalously low. The current quarterly water level at TW4-27
(approximately 5528.3 ft amsl) is nearly 5 feet lower than the water level at TW4-14 (5533.2 ft
amsl). Recent increases in water level differences between TW4-14 and TW4-27 are due to more
rapid increases in water levels at TW4-14 resulting from past delivery of water to the northern
wildlife ponds. The rate of water level increase at TW4-27 is smaller than at TW4-14 because
TW4-27 is farther downgradient of the ponds.
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 TW 4-4 and TW 4-6
(respectively); however chloroform exceeding 70 !J.giL has been detected at relatively 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 low water level at TW4-14. The water level at TW4-26 (5534.6
feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5536.1 feet amsl), and
TW4-23 (5537.6 feet amsl).
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 Oeo Chern, Inc. [HOC],
September 20, 2010: Hydraulic Testing of TW4-4, TW4-6, and TW4-26, White Mesa Uranium
Mill, July 2010; and HOC, 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 relatively 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: HOC, January 23, 2014, Contamination
Investigation Report, TW4-12 and TW4-27 Areas, White Mesa Uranium Mill Near Blanding,
Utah; and HOC, 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.
15
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 first quarter, 2016 chloroform concentrations of 6.2 [!giL
and 3.2 [!giL, respectively. In addition, the relatively low permeability and comparative
hydraulic isolation of these wells reduces their responses to changing hydraulic conditions
resulting from pumping and reduced wildlife pond recharge.
Chloroform exceeding 70 [!giL detected at TW4-29 and TW4-33 since their relatively recent
installation in 2013 indicates that, in addition to migrating south from TW4-4 to TW4-6 and
TW4-26, chloroform also migrated along a 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 relatively recently, placed TW4-14 almost directly downgradient of TW4-
4. Such migration was historically possible because the water levels at TW4-29 have been lower
than the water levels at TW4-4 (and TW4-6). The permeability and historic water level
distributions are generally consistent with the apparent nearly cross-gradient migration of
chloroform from TW4-4 around the low permeability zone defined by TW4-36, TW4-14, and
TW4-27.
Chloroform during the current quarter was detected at approximately 7.4 [!giL at relatively
recently installed well TW4-30 (located east and downgradient of TW4-29), and was not
detected at relatively recently installed wells TW4-31 (located east of TW4-27), TW4-34
(located south and cross-gradient of TW4-29), nor TW4-35 (located southeast and cross-to
downgradient of TW4-29).
Data from existing and relatively recently installed wells indicate that:
1. Chloroform exceeding 70 f.tg/L at TW4-29 is bounded by concentrations below 70 [!giL at
wells TW4-26, TW4-27, TW4-30, TW4-34, and TW4-35. TW4-30 is downgradient of
TW4-29; TW4-26 is cross-to upgradient ofTW4-29; and TW4-27, TW4-34 and TW4-35
are cross-to downgradient ofTW4-29.
2. Chloroform concentrations at TW4-33 that are lower than concentrations at TW4-29, and
the likelihood that a pathway exists from TW4-4 to TW4-33 to TW4-29, suggest that
concentrations in the vicinity of TW4-33 were likely higher prior to initiation of TW4-4
pumping, and that lower concentrations currently detected at TW4-33 are due to its closer
proximity to TW4-4.
Furthermore, TW4-4 pumping is likely to eventually reduce chloroform at both TW4-33 and
TW4-29 by cutting off the source. The decrease at TW4-33 is expected to be faster than at TW4-
29 because TW4-33 is in closer proximity to TW4-4 pumping. Such behavior is expected by
analogy with the decreases in chloroform concentrations that occurred at TW4-6 and TW4-26
once TW4-4 pumping began. Since installation in 2013, however, concentrations at TW4-33
appear to be relatively stable to decreasing; since the third quarter of 2014, concentrations at
TW4-29 appear to be generally increasing.
16
Relatively stable chloroform at TW4-33 and generally increasing concentrations at TW4-29
suggest that chloroform migration has been arrested at TW4-33 by TW4-4 pumping and that
increasing chloroform at downgradient well TW4-29 results from a remnant of the plume that
continues to migrate downgradient (toward TW4-30, which bounds to plume to the east). The
influence of TW4-4 pumping at the distal end of the plume is consistent with generally
decreasing water levels at both TW4-29 and TW4-33.
Detectable chloroform concentrations at TW4-14 (since the fourth quarter of 2014) and TW4-27
(since the third quarter of 2015) are consistent with continued, but slow, downgradient migration
of chloroform from the distal end of the plume (defined by TW4-29 and TW4-33) into the low
permeability materials penetrated by TW4-14 and TW4-27.
4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater Contour
Maps for Previous Quarter
The groundwater contour map for the Mill site for the first quarter of 2016, as submitted with the
Chloroform Monitoring Report for the first quarter of 2016, is attached under Tab E. Small (<1
foot) changes in water levels were reported at the majority of site wells~ water levels and water
level contours for the site have not changed significantly since the last qua1ter except for a few
locations.
A comparison of the water table contour maps for the current quarter (second quarter of 2016) to
the water table contour maps for the previous quarter (first quarter of 2016) indicates similar
patterns of drawdowns associated with the pumping wells. Nitrate pumping wells TW4-22,
TW4-24, TW4-25, and TWN-2 were brought into operation during the first quarter of 2013 and
their impact on water level patterns has been apparent since the fourth quarter of 2013. Although
a large expansion in capture occurred with the addition of chloroform pumping wells TW 4-1,
TW4-2, TW4-11, TW4-21 and TW4-37 in 2015, a significant cone of depression associated with
TW4-37 is not yet evident.
Drawdowns at chloroform pumping well TW4-2 and nitrate pumping well TWN-2 increased by
more than 2 feet this quarter. Water level changes at other nitrate and chloroform pumping wells
were less than 2 feet, 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 slightly 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 of the combined pumping system is
approximately the same as last quarter.
As discussed in Section 4.1.1, pumping at chloroform well TW4-4, which began in the first
quarter of 2010, has depressed the water table near TW4-4, but a well-defined cone of depression
is not clearly evident, likely due to variable permeability conditions near TW4-4 and the
persistently low water level at adjacent well TW 4-14.
17
Reported water level decreases of up to 0.94 feet at Piezometers 1, 2, 4, and 5, TWN-1, and
TWN-4 may result from cessation of water delivery to the northern wildlife ponds as discussed
in Section 4.1.1 and the consequent continuing decay of the associated perched water mound.
Reported water level decreases of approximately 0.88 feet and 0.94 feet at Piezometers 4 and 5,
respectively, may also result from reduced recharge at the southern wildlife pond.
Reported water levels decreased by approximately 3 feet at MW-20, and increased by
approximately 9 feet and 3 feet, respectively, at MW-14 and TWN-19. Water level variability at
MW-20 likely results from low permeability and variable intervals between purging/sampling
and water level measurement. The increase at MW -14 compensates for the reported decrease last
quarter, suggesting that last quarter's reading was anomalous. The increase at TWN-19, located
at the far up gradient corner of the property, may have resulted from offsite influences.
Measurable water was again reported at DR-22. Although DR-22 is typically dry, measurable
water has been reported in the bottom of its casing since the second quarter of 2015.
4.1.3 Hydrographs
Attached under Tab F are hydrographs showing groundwater elevation in each chloroform
contaminant investigation monitor well over time.
4.1.4 Depth to Groundwater Measured and Groundwater Elevation
Attached under Tab F are tables showing depth to groundwater measured and groundwater
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, TW4-4, TW4-19, and TW4-20, and, since the first
half of 2015, wells TW4-1, TW4-2, TW4-11, TW4-21, and TW4-37. The primary purpose of
the pumping is to reduce total chloroform mass in the perched zone as rapidly as is practical.
Pumping wells up gradient of TW 4-4 were chosen because 1) they are located in areas of the
perched zone having relatively high permeability and saturated thickness, and 2) high
concentrations of chloroform were detected at these locations. The relatively high transmissivity
of the perched zone in the vicinity of these pumping wells results in the wells having a relatively
high productivity. The combination of relatively high productivity and high chloroform
concentrations allows for a high rate of chloroform mass removal. TW 4-4 is located in a
downgradient area having relatively high chloroform concentrations but relatively small
saturated thickness, and at a transition from relatively high to relatively low permeability
conditions downgradient of TW 4-4. As with the other chloroform pumping wells, pumping
TW 4-4 helps to reduce the rate of chloroform migration in downgradient portions of the plume.
The impact of chloroform pumping is indicated by the water level contour maps attached under
Tabs D and E. Cones of depression are evident in the vicinity of MW -4, MW-26, TW 4-19, and
TW4-20 which continue to remove significant quantities of chloroform from the perched zone.
18
Relatively large cones of depression have developed in the vicinities of wells TW4-1, TW4-2,
and TW4-11 which began pumping during the first quarter of 2015, and at TW4-21 which began
pumping during the second quarter of 2015. A cone of depression in the vicinity of chloroform
pumping well TW4-37, which began pumping during the second quarter of 2015, is not yet
evident. The water level contour maps indicate effective capture of water containing high
chloroform concentrations in the vicinities of these pumping wells. As discussed in Section
4.1.1, although chloroform pumping well TW 4-4 became operational in 2010, the draw down
associated with TW 4-4 is likely less apparent due to variable permeability conditions near TW 4-
4 and the persistently low water level at adjacent well TW4-14.
Compared to last quarter, both increases and decreases in water levels occurred at nitrate and
chloroform pumping wells. The water levels in chloroform pumping wells MW-26, TW4-1,
TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, and TW4-37 decreased by approximately 0.6, 1.6,
3.9, 0.9, 1.6, 0.5, 1.5, and 0.7 feet respectively, while the water levels in chloroform pumping
wells MW-4 and TW4-21 increased by approximately 0.2 and 0.05 feet, respectively. The water
level in nitrate pumping wells TWN-2 and TW4-25 decreased by approximately 4 feet and 0.2
feet, respectively, while the water levels in nitrate pumping wells TW4-22 and TW4-24
increased by approximately 0.5 and 1.9 feet, respectively. Overall, the apparent capture of the
combined pumping systems is about the same as last quarter.
The capture associated with nitrate pumping wells and chloroform pumping wells added in 2015
is expected to increase over time as water levels continue to decline due to cessation of water
delivery to the northern wildlife ponds and continued pumping. Slow development of hydraulic
capture is consistent with and expected based on the relatively low permeability of the perched
zone at the site.
The hydraulic capture effectiveness of both chloroform and nitrate pumping systems depends to
some extent on the continued productivity of chloroform and nitrate pumping wells. Decreases in
productivity have been noted since the third quarter of 2014 in chloroform pumping well TW4-
19 and nitrate pumping well TW4-24. The impact of reduced productivity of these wells on
chloroform capture was discussed in Attachment N (Tab N) of the third quarter, 2015 report. The
report also included a discussion of the effectiveness of chloroform pumping on chloroform
capture. 'Background' flow through the chloroform plume was calculated in Attachment N as
approximately 3.3 gpm. A more refined 'background' flow calculation of 3.4 gpm was provided
in the CACME Report (See HGC, March 31, 2016: Corrective Action Comprehensive
Monitoring Evaluation Report, White Mesa Uranium Mill, Near Blanding, Utah).
Pumping from the chloroform plume during the current quarter (from wells MW-4, MW-26,
TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22, TW4-24, and TW4-37)
is approximately 4.8 gpm, which exceeds the calculated background flow by 1.4 gpm or 41%.
Therefore chloroform pumping is considered adequate at the present time even with the reduced
productivities of TW 4-19 and TW 4-24. 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.
19
Chloroform concentrations at many locations have been or appear to be affected by changes
associated with reduced dilution from the wildlife ponds and nitrate pumping. For example,
increases in chloroform at TW4-22 and TW4-24 after these wells were converted to nitrate
pumping wells are attributable to westward migration of chloroform from the vicinity of TW4-20
toward these wells. The increase in concentration at TW 4-8 from non-detect to 100 f!g/L in the
first quarter of 2014 (and to 595 f!g/L this quarter) is likely related to reduced dilution. Although
the chloroform concentration in TW4-6 decreased from 834 f!g/L to 436 f!g/L this quarter,
concentrations at TW4-6 have increased from approximately 10 11g1L since the second quarter of
2014. These changes are likely related to both reduced dilution and more westward flow induced
by nitrate pumping.
TW4-6 is located immediately south and cross-to downgradient of chloroform pumping well
TW4-4. Chloroform concentrations at TW4-6 exceeded 70 11g1L between the first quarter of
2009 and the third quarter of 2010, and remained below 70 11g1L between the fourth quarter of
2010 and the second qumter of 2014. Relatively low permeability and relatively small saturated
thickness in the vicinity of TW 4-6 limit the rate at which chloroform mass can be removed by
pumping. However, pumping at more productive upgradient locations such as TW4-4 enhances
mass removal and lowers hydraulic gradients, thereby reducing the rate of downgradient
chloroform migration and allowing natural attenuation to be more effective. Pumping at TW4-4
was implemented during the first quarter of 2010 to improve capture downgradient of TW 4-4 to
the extent allowable by the lower productivity conditions present in this area. The beneficial
effect of pumping TW 4-4 is demonstrated by the net decreases in TW 4-6 chloroform
concentrations from 1,000 11g/L to 10.3 f!g/L, and in TW4-26 from 13 11g1L to 4.2 f!g/L, between
the initiation of TW 4-4 pumping and the second quarter of 2014. Concentrations at these wells
decreased substantially even though they do not unambiguously appear to be within the
hydraulic capture of TW4-4. As discussed in Section 4.1.1, however, the decrease in the long-
term rate of water level rise at TW 4-6 after TW 4-4 began pumping does suggest that TW 4-6 is
within the hydraulic influence of TW 4-4. The decline in water levels at TW 4-6 since the fourth
quarter of 2013 likely reflects the additional influences of cessation of water delivery to the
wildlife ponds and the addition of chloroform pumping wells TW 4-1, TW 4-2, and TW 4-11.
Regardless of whether TW4-6 can be demonstrated to be within the hydraulic capture of TW4-4,
pumping TW4-4 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 f!g/L in the second
quarter of 2004 to less than 70 11g/L by the fourth quarter of 2005, and maintained concentrations
below 70 11g/L until the second quarter of 2014, even though TW4-16 appears to be just beyond
the hydraulic capture of MW-26. Furthermore, the overall hydraulic capture of the chloroform
pumping system has expanded since initiation of pumping at wells TW4-1, TW4-2, TW4-11
TW4-21 and TW4-37 during the first half of 2015. Operation of these additional wells may have
reversed the increase in concentration at TW 4-16 which dropped from 387 11g1L in the fourth
quarter of 2014 to less than 70 11g1L in the second quarter of 2015. Chloroform at TW4-16 was
detected at 93 f!g/L this quarter.
20
Chloroform exceeding 70 f!g/L was detected at relatively recently installed well TW4-29, located
south of TW4-27 and east of TW4-26, and generally cross-gradient of TW4-4 and TW4-6 with
respect to the groundwater flow directions implied by groundwater elevations in the area. As
discussed in Section 4.1.1, this may represent chloroform migrating 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 f!g/L detected at relatively recently installed
well TW4-33, 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 is likely to eventually reduce chloroform
at both TW4-33 and TW4-29 by cutting off the source. The impact at TW4-33 is expected to be
greater than at TW4-29 because TW4-33 is in closer proximity to TW4-4 pumping. Such
behavior is expected by analogy with the decreases in chloroform concentrations at TW 4-6 and
TW4-26 that occurred once TW4-4 pumping began. However, concentrations at both TW4-29
and TW4-33 were relatively stable (rather than decreasing) for several quarters after installation.
Concentrations at TW4-29 appear to be on an upward trend since the third quarter of 2014. As
discussed in Section 4.1.1, although decreasing concentration trends at both wells are eventually
expected to occur, relatively stable chloroform at TW4-33 and recent increases in concentration
at TW4-29 suggest that chloroform migration has been arrested at TW4-33 by TW4-4 pumping
and that increasing chloroform at downgradient well TW 4-29 results from a remnant of the
plume that continues to migrate downgradient (toward TW4-30, which bounds to plume to the
east). The influence of TW4-4 pumping at the distal end of the plume is consistent with generally
decreasing water levels at both TW4-29 and TW4-33.
In addition, detectable chloroform concentrations at TW4-14 (since the fourth quarter of 2014)
and TW4-27 (since the third quarter of 2015) are consistent with continued, but slow,
downgradient migration of chloroform from the distal end of the plume into the low permeability
materials penetrated by these wells.
Chloroform analytical results from relatively recently installed wells TW4-35 and TW4-36 (as
discussed in Section 4.2.3) demonstrate that chloroform is bounded to the southeast of TW4-29
and to the east ofTW4-8.

nitrate/nitrite, carbon tetrachloride, chloroform, chloromethane, and methylene chloride, for each
well over time.
Attached under Tab K are graphs showing chloroform concentration trends in each monitor well
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-4, TW4-4, TW4-5, TW4-11, TW4-14, TW4-16, TW4-19,
TW4-20, TW4-22, TW4-24, TW4-26, TW4-27, and TW4-30;
b) Chloroform concentrations decreased by more than 20% m the following wells
compared to last quarter: MW-26, TW4-6, and TW4-33;
c) Chloroform concentrations have remained within 20% in the following wells compared
to last quarter: TW4-1, TW4-2, TW4-7, TW4-8, TW4-9, TW4-10, TW4-18, TW4-29,
and TW4-37;
d) Chloroform concentrations have remained non-detect in the following wells: MW-32,
TW4-3, TW4-12, TW4-13, TW4-23, TW4-25, TW4-28, TW4-31, TW4-32, TW4-34,
TW4-35, and TW4-36.
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-4, MW-26,
TW4-4, TW4-5, TW4-6, TW4-11, TW4-14, TW4-16, TW4-19, TW4-20, TW4-22, TW4-24,
TW4-26, TW4-27, TW4-30 and TW4-33 had changes in concentration greater than 20%. Of
these, MW-4, MW-26, TW4-4, TW4-11, TW4-19, and TW4-20 are chloroform pumping wells;
and TW4-22 and TW4-24 are nitrate pumping wells. TW4-5 is located just outside the plume
margin and near chloroform pumping wells TW4-19 and TW4-20; TW4-6 is located adjacent to
chloroform pumping well TW 4-4 near the down gradient edge of the plume; TW 4-14 is located
adjacent to chloroform pumping well TW4-4; and TW4-16 is located adjacent to chloroform
pumping wells TW4-11 and MW-26. Fluctuations in concentrations at both chloroform and
nitrate pumping wells and wells adjacent to pumping wells likely result in part from changes in
pumping.
TW4-26 is located immediately southwest of the plume boundary. TW4-14 and TW4-27 are
located immediately east of the plume boundary. Currently, TW4-14 is located cross-to
downgradient of TW4-4, and TW4-27 is generally downgradient of TW4-33. TW4-30 is located
22
just outside the plume boundary immediately east (and downgradient) of TW4-29, and TW4-33
is located just within the southeast boundary of the plume. Fluctuations in concentrations at these
wells are expected based on their locations at the plume margins.
Chloroform pumping wells TW4-19, TW4-20 and TW4-37, and nitrate pumping well TW4-22,
had the highest detected chloroform concentrations of 12,600, 33,700, 16,200, and 8,570 ~-tg!L,
respectively. Since last quarter, the chloroform concentration in TW4-19 increased from 7,780
~-tg!L to 12,600 ~-tg!L; TW4-20 increased from 21,600 ~-tg!L to 33,700 ~-tg/L; TW4-37 decreased
from 17,500 to 16,200 ~-tg!L; and the concentration in nearby pumping well TW4-21 increased
from 390 to 545 ~-tg!L. The chloroform concentration in nitrate pumping well TW4-22 increased
from 6,070 ~-tg!L to 8,570 ~-tg!L. The chloroform concentration in nitrate pumping well TW4-24
increased from 22.8 to 69.6 ~-tg!L and remains just outside the chloroform plume. Nitrate
pumping well TW4-25 remained non-detect for chloroform. TW4-25, located north of TW4-21,
bounds the chloroform plume to the north.
Chloroform at TW4-8 (which was non-detect from the first quarter of 2008 through the fourth
quarter of 2013) decreased from 634 ~-tg!L to 595 ~-tgiL. TW4-8 is located immediately east of
chloroform pumping well MW-4, where chloroform was detected at a concentration of 1,580
~-tg!L. From the first quarter of 2005 through the fourth quarter of 2013, the plume boundary
remained between MW-4 and TW4-8. The occurrence of elevated chloroform at TW4-8 is likely
related to its location along the eastern plume boundary immediately east of pumping well MW-
4. Changes in the plume boundary near TW 4-8 are expected to result from changes in pumping
and reduced dilution resulting from cessation of water delivery to the northern wildlife ponds.
Chloroform at TW4-8 is bounded to the north by TW4-3 (non-detect), to the northeast by TW4-
13 (non-detect), to the east by TW4-36 (non-detect), and to the southeast by TW4-14 (6.2 ~-tg!L).
The increase in chloroform at TW4-14 from approximately 4.5 ~-tg!L to 6.2 ~-tg/L, and at TW4-27
from approximately 2.1 ~-tg!L to approximately 3.2 ~-tg!L is consistent with ongoing, but slow,
downgradient migration.
Chloroform at relatively recently installed well TW4-29 (located at the southern tip of the plume,
to the east of TW4-26 and to the south of TW4-27) increased from 335 f!g/L to 366 ~-tg/L.
Chloroform at TW4-30, located immediately downgradient of TW4-29, increased from
approximately 5.2 ~-tg/L to approximately 7.4 f!g/L. As with TW4-27, the change at TW4-30 is
consistent with ongoing, but slow, downgradient migration. Chloroform at TW4-29 is bounded
to the north by TW4-27 (3.2 ~-tg!L), to the east by TW4-30 (7.4 ~-tg!L), to the southeast by TW4-
35 (non-detect), to the south by TW4-34 (non-detect), and to the west by TW4-26 (8.2~-tg!L).
Chloroform at relatively recently installed well TW4-33 (located between TW4-4 and TW4-29)
showed a decrease in concentration, from 122 ~-tg!L to 96 ~-tg!L. Chloroform at TW4-33 is
bounded to the north by TW4-14 (6.2 ~-tg/), to the east by TW4-27 (3.2 ~-tg!L), to the west by
TW4-23 (non-detect), and to the south and west by TW4-26 (8.2 ~-tg!L). This chloroform
distribution indicates that the plume southeast of TW 4-4 is very narrow compared to more
upgradient locations.
The chloroform concentration in TW4-6 decreased from 834 ~-tg!L to 486 ~-tg!L, and remains
within the chloroform plume boundary. Concentrations at TW4-6 exceeded 70 ~-tg!L from the
23
first quarter of 2009 through the third quarter of 2010, and then remained below 70 [!giL until
the third quarter of 2014. Between initiation of pumping of TW4-4 in the first quarter of 2010
and the second quarter of 2014, concentrations at TW4-6 showed a net decrease from 1,000 [!giL
to 10.3 [!giL. TW4-6, installed in the second quarter of 2000, was the most downgradient
temporary perched well prior to installation of temporary well TW4-23 in 2007 and temporary
well TW4-26 in the second quarter of 2010. TW4-6 remained outside the chloroform plume
between the second quarter of 2000 and the fourth quarter of 2008. TW4-6 likely remained
outside the chloroform plume during this time due to a combination of 1) slow rates of
downgradient chloroform migration in this area due to low permeability conditions and the
effects of up gradient chloroform removal by pumping, and 2) natural attenuation.
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 up gradient well TW 4-4. Concentrations at TW 4-4 increased from non-detect to
more than 2,200 [!giL within only 2 quarters whereas 16 quarters were required for
concentrations in TW4-6 to increase from non-detect to only 81 [!g/L. This behavior is consistent
with hydraulic tests performed at TW4-4, TW4-6, and TW4-26 during the third quarter of 2010
that indicate a nearly two order of magnitude decrease in permeability south (downgradient) of
TW4-4. Chloroform migration rates in the vicinity of well TW4-26 and relatively recently
installed wells TW4-29 and TW4-33 are also expected to be relatively slow due to upgradient
pumping and relatively low permeability conditions. By analogy with the decreases in
concentration at TW4-6 and TW4-26 that occurred after initiation of TW4-4 pumping,
chloroform concentrations at TW4-29 and TW4-33 are expected to eventually trend downward.
Although changes in concentration have occurred in wells within the chloroform plume, the
boundaries of the plume have not changed significantly since the last quarter, except for a slight
expansion near TW4-16 (which is just inside the plume this quarter). The chloroform
concentration at TW4-9 increased slightly from approximately 74 [!giL to 76 [!g/L, and remains
just within the plume. Except for the fourth quarter of 2014, TW4-9 was outside the plume prior
to the first quarter of 2016. The plume boundary remains between TW4-9 and TW4-12 (which is
non-detect for chloroform and cross-gradient of TW4-9). The increase at TW4-9 is attributable to
reduced recharge (and dilution) from the northern wildlife ponds.
Nitrate pumping generally caused the western boundary of the northern portion of the
chloroform plume to migrate to the west toward TW4-24. Since the first quarter of 2014, TW4-
24 has been both inside and outside the plume and remains outside the plume this quarter, likely
due to initiation of TW4-37 pumping in the second quarter of 2015 and reduced productivity at
TW4-24 (since the third quarter of 2014). Since the second quarter of 2014, generally increased
concentrations at TW4-6 and TW4-16 (both of which were within the chloroform plume in the
past) indicate that the plume boundary migrated to the southwest and re-incorporated both wells.
TW4-6 remains within the plume this quarter and TW4-16 (with a concentration increase from
approximately 46 [!giL to 93 [!g/L) is again inside the plume. Increases at these wells beginning
in the second quarter of 2014 are likely related to reduced dilution from cessation of water
delivery to the northern wildlife ponds and more westerly flow induced by nitrate pumping.
However, continued operation of the nitrate pumping system is expected to enhance the capture
zone associated with the chloroform pumping system even though nitrate pumping may
24
redistribute chloroform within the plume and cause changes in the plume boundaries.
Furthermore, the addition of chloroform wells TW4-l, TW4-2, TW4-11, TW4-21 and TW4-37
to the chloroform pumping network in the first half of 2015 is expected to have a beneficial
impact. Generally reduced concentrations at TW4-6 and TW4-16 after previous increases are
likely the result of initiation ofTW4-1, TW4-2, and TW4-11 pumping.
5.0 LONG TERM PUMP TEST AT MW-4, MW-26, TW4-19, TW4-20, AND TW4-4
OPERATIONS REPORT
5.1 Introduction
As a part of the investigation of chloroform contamination at the Mill site, EFRI has been
conducting a Long Term Pump Test on MW-4, TW4-19, MW-26, and TW4-20, and, since
January 31, 2010, TW 4-4. The purpose of the test is to serve as an interim action that will
remove a significant amount of chloroform-contaminated water while gathering additional data
on hydraulic properties in the area of investigation.
Beginning in January 2013, EFRI began long term pumping of TW4-22, TW4-24, TW4-25, and
TWN-02 as required by the Nitrate CAP, dated May 7, 2012 and the Stipulated Consent Order
(the "SCO") dated December 12, 2012. Because wells TW4-22, TW4-24, and TW4-25 are
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 ofTW4-1, TW4-2, and TW4-11
and began long term pumping of TW4-21 and TW4-37 on June 9, 2015.
The following information documents the operational activities during the quarter.
5.2 Pump Test Data Collection
The long term pump test for MW-4 was started on April 14, 2003, followed by the start of
pumping from TW4-19 on April 30, 2003, from MW-26 on August 8, 2003, from TW4-20 on
August 4, 2005, from TW4-4 on January 31, 2010, and from TW4-22, TW4-24, and TW4-25 on
January 26, 2013. Personnel from Hydro Geo Chern, Inc. were on site to conduct the first phase
of the pump test and collect the initial two days of monitoring data for MW -4. EFRI personnel
have gathered subsequent water level and pumping data.
Analyses of hydraulic parameters and discussions of perched zone hydrogeology near MW -4 has
been provided by Hydro Geo Chern in a separate report, dated November 12, 2001, and in the
May 26,2004 Final Report on the Long Term Pumping Test.
Data collected during the quarter included the following:
• Measurement of water levels at MW-4, TW4-19, MW-26, TW4-20, and TW4-4,
on a weekly basis, and at selected temporary wells and permanent monitoring
wells on a monthly basis.
• Measurement of pumping history, including:
25
pumping rates
to tar pumped volume
operational and non-operational periods.
• Periodic sampling of pumped water for chloroform and nitrate/nitrite analysis and
other constituents
• Measurement of water levels weekly at TW4-22, TW4-24, TW4-25, and TWN-02
commencing January 28, 2013, and on a monthly basis for selected temporary
wells and permanent monitoring wells.
5.3 Water Level Measurements
Beginning August 16, 2003, the frequency of water level measurements from MW-4, MW-26,
and TW4-19 was reduced to weekly. From commencement of pumping TW4-20, and regularly
after March 1, 2010 for TW4-4, water levels in these wells have been measured weekly. From
commencement of pumping, water levels in wells TW4-1, TW4-2, TW4-11, TW4-21, TW4-22,
TW4-24, TW4-25, TW4-37, 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, TW4-20, TW4-21, TW4-4, TW4-22, TW4-24, TW4-25, TW4-37, 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.
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 39.4 lb., which is 29% greater than the approximately 30.6 lb.
26
removed last quarter. The mass removed this quarter is the highest since the fourth quarter of
2009 and the second highest ever calculated.
The residual mass of chloroform within the plume is estimated as 2,261 lb. using the
methodology described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation
Method"). This is approximately 315 lb. more than last quarter's estimate of 1,946 lb. and is
attributable to higher average chloroform concentrations within the plume and slight expansion
of the plume to the southwest to re-incorporate TW4-16 this quarter. As per Part ill.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 upward.
Subsequent residual plume mass estimates will be calculated quarterly, added to the graph, and
the trendline updated as per Part III.B.3 of the GCAP.
As discussed in the CACME Report, the calculated chloroform mass has been generally
increasing since the cessation of water delivery to the two northern wildlife ponds in the first
quarter of 2012. These ponds are located immediately upgradient of the chloroform plume. The
calculated mass has increased as the plume area and the average concentrations within the plume
have increased. The increases in plume area and average concentrations are both attributable to
reduced recharge and reduced dilution from chloroform-free wildlife pond seepage.
However, the rate of mass removed per quarter by pumping has also increased, in particular
since the addition of 5 new pumping wells in the first half of 2015. The mass removal this
quarter is the second highest ever calculated. 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, and 2015 ranged from approximately 84% to 93%. The
proportion of the mass of the plume under capture this quarter is approximately 91%.
5.6 Inspections
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
No water was added to the any of the wildlife ponds during the quarter.
6.0 CORRECTIVE ACTION REPORT
There are no corrective actions required during the current monitoring period.
6.1 Assessment of Previous Quarter's Corrective Actions
There are no corrective actions required during the previous 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
!J.g!L (Tab J). The plume is bounded to the north by TW 4-25 (non-detect); to the west and
southwest by MW-31 (non-detect), MW-32 (non-detect), TW4-23 (non-detect), TW4-24 (69.6
!J.giL), and TW4-26 (approximately 8.2 !J.g/L); to the east by TW4-3 (non-detect), TW4-5
(approximately 14 !J.g/L), TW4-12 (non-detect), TW4-13 (non-detect), TW4-14 (approximately
6.2 !J.giL), TW4-18 (approximately 60 !J.giL), TW4-27 (approximately 3.2 !J.g/L), TW4-30
(approximately 7.4 !J.giL), and TW4-36 (non-detect); to the south by TW4-34 (non-detect); and
to the southeast by TW4-35 (non-detect).
Data collected to date indicate there are sufficient chloroform monitoring and pumping wells to
effectively define, control, and monitor the plume.
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. No new wells were installed
during the quarter and all previously installed wells were installed in accordance with the GCAP
requirements. The existing wells were maintained and operated as required. Additional details
regarding any specific pumping well operations and maintenance issues noted during the quarter
are discussed in Section 5.0 above.
7.3 Disposal of Extracted Groundwater
Part II of the GCAP requires that all extracted groundwater be disposed of in the tailings
management system or fed in the Mill process. All extracted groundwater was handled as
required by the GCAP.
7.4 Compliance Well Performance
Part II.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 for TW 4-9. As
noted above, an exceedance is defined as the presence of chloroform in any compliance
monitoring well in excess of 70 ug/L for two or more quarters. The previously reported
chloroform concentration for TW4-9 was 74.3 ug!L and the current concentration is 76.2 ug!L.
Because an exceedance of chloroform in TW 4-9 has been reported two or more consecutive
quarters, an Exceedance Notice and Plan and Time Schedule are required and will be submitted
in accordance with the schedule required by the GCAP. A copy of the Exceedance Notice is
included in Tab N.

7.5 Chloroform Plume Monitoring for Wells within 500 Feet of the Property Boundary
Currently there are no compliance wells within 500 feet of the property boundary.
8.0 CONCLUSIONS AND RECOMMENDATIONS
The residual mass of chloroform within the plume is estimated as 2,261 lb. using the
methodology described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation
Method"). This is approximately 315 lb. more than last quarter's estimate of 1,946 lb. and is
attributable to higher average chloroform concentrations within the plume and slight expansion
of the plume to the southwest to re-incorporate TW 4-16 this quarter. The mass of chloroform
removed from the plume this quarter is approximately 39.4 lb., which is 29% greater than the
approximately 30.6 lb. removed last quarter. The mass removed this quarter is the highest since
the fourth quarter of 2009 and the second highest ever calculated.
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
flg/L. The plume is bounded to the north by TW4-25; to the west and southwest by MW-31,
MW-32, TW4-23, TW4-24, and TW4-26; to the east by TW4-3, TW4-5, TW4-12, TW4-13,
TW4-14, TW4-18, TW4-27, TW4-30, and TW4-36; to the south by TW4-34; and to the
southeast by TW4-35. Data collected to date indicate there are sufficient chloroform monitoring
and pumping wells to effectively define, control, and monitor the plume.
The water level contour maps for the first quarter, 2016 indicate effective capture of water
containing high chloroform concentrations in the vicinity of chloroform pumping wells MW -4,
MW-26, TW4-19, and TW4-20. Capture in the 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. Well-
defined capture zones are not clearly evident at chloroform pumping well TW4-37 which began
pumping during the second quarter of 2015, or at TW4-4. The capture zone associated with
TW4-4 is likely obscured by the low water level at adjacent well TW4-14 and the two orders of
magnitude decrease in permeability south of TW4-4. However, between the first quarter of 2010
and the second quarter of 2014, decreases in chloroform concentrations and the rate of water
level rise at TW4-6 (located downgradient of TW4-4) likely resulted from TW4-4 pumping.
Cones of depression associated with the nitrate pumping wells became evident as of the fourth
quarter, 2013, and capture associated with the nitrate pumping is expected to continue to
develop. The start-up of chloroform pumping wells TW4-21 and TW4-37 during the second
quarter of 2015 is also expected to increase capture and chloroform removal rates. Overall
capture this quarter is about the same as last quarter.
'Background' flow through the chloroform plume was calculated as approximately 3.4 gpm as
presented in CACME Report (See HGC, March 31, 2016: Corrective Action Comprehensive
Monitoring Evaluation Report, White Mesa Uranium Mill, Near Blanding, Utah). Pumping from
the chloroform plume during the current quarter (from wells MW-4, MW-26, TW4-1, TW4-2,
TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22, TW4-24, and TW4-37) is
approximately 4.8 gpm, which exceeds the calculated background flow by 1.4 gpm or 41%.
Therefore chloroform pumping is considered adequate at the present time.
29
Chloroform concentrations at many of the wells with detected chloroform were within 20% of
the values reported during the previous quarter, suggesting that variations are within the range
typical for sampling and analytical error. Changes in concentration greater than 20% occurred in
wells MW-4, MW-26, TW4-4, TW4-5, TW4-6, TW4-11, TW4-14, TW4-16, TW4-19, TW4-20,
TW4-22, TW4-24, TW4-26, TW4-27, TW4-30 and TW4-33. Of these, MW-4, MW-26, TW4-4,
TW4-11, TW4-19, and TW4-20 are chloroform pumping wells; and TW4-22 and TW4-24 are
nitrate pumping wells. TW4-5 is located just outside the plume margin and near chloroform
pumping wells TW4-19 and TW4-20; TW4-6 is located adjacent to chloroform pumping well
TW4-4 near the downgradient edge of the plume; TW4-14 is located adjacent to chloroform
pumping well TW4-4; and TW4-16 is located adjacent to chloroform pumping wells TW4-11
and MW-26. 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,
changes in concentrations at chloroform wells are expected to result from continued operation of
nitrate pumping wells as the capture associated with nitrate pumping expands and flow directions
change locally.
TW4-26 is located immediately southwest of the plume boundary. TW4-14 and TW4-27 are
located immediately east of the plume boundary. Currently, TW4-14 is located cross-to
downgradient of TW4-4, and TW4-27 is generally downgradient of TW4-33. TW4-30 is located
just outside the plume boundary immediately east (and downgradient) of TW4-29; and TW4-33
is located just within the southeast margin of the plume. Fluctuations in concentrations at these
wells are expected based on their locations at the plume margins.
Chloroform at TW4-8 (which was non-detect from the first quarter of 2008 through the fourth
quarter of 2013) decreased from 634 (lg/L to 595 (lg/L. TW4-8 is located immediately east of
chloroform pumping well MW-4, where chloroform was detected at a concentration of 1,580
(lg/L. From the first quarter of 2005 through the fourth quarter of 2013, the plume boundary
remained between MW-4 and TW4-8. The occurrence of elevated chloroform at TW4-8 is likely
related to its location along the eastern plume boundary immediately east of pumping well MW-
4. Changes in the plume boundary near TW4-8 are expected to result from changes in pumping
and reduced dilution resulting from cessation of water delivery to the northern wildlife ponds.
Chloroform at TW4-8 is bounded to the north by TW4-3 (non-detect), to the northeast by TW4-
13 (non-detect), to the east by TW4-36 (non-detect), and to the southeast by TW4-14 (6.2 f!g/L).
The increase in chloroform at TW4-14 from approximately 4.5 f!giL to 6.2 f!g/L, and at TW4-27
from approximately 2.1 f!g/L to approximately 3.2 f!giL is consistent with ongoing, but slow,
downgradient migration.
Chloroform pumping wells TW4-19, TW4-20 and TW4-37, and nitrate pumping well TW4-22,
had the highest detected chloroform concentrations of 12,600, 33,700, 16,200, and 8,570 f!g/L,
respectively. Since last quarter, the chloroform concentration in TW4-19 increased from 7,780
f!g/L to 12,600 f!g/L; TW4-20 increased from 21,600 f!g/L to 33,700 f!g/L; TW4-37 decreased
from 17,500 to 16,200 f!g/L; and the concentration in nearby pumping well TW4-21 increased
from 390 to 545 f!g/L. The chloroform concentration in nitrate pumping well TW4-22 increased
from 6,070 f!g/L to 8,570 f!g/L. The chloroform concentration in nitrate pumping well TW4-24
increased from 22.8 to 69.6 f!g/L and remains just outside the chloroform plume. Nitrate
30
pumping well TW4-25 remained non-detect for chloroform. TW4-25, located north of TW4-21,
bounds the chloroform plume to the north.
Chloroform at relatively recently installed well TW 4-29 (located at the southern tip of the plume,
to the east of TW4-26 and to the south of TW4-27) increased from 335 ~-tg/L to 366 ~-tg/L.
Chloroform at TW4-30, located immediately downgradient of TW4-29, increased from
approximately 5.2 ~-tg/L to approximately 7.4 ~-tg/L. As with TW4-27, the change at TW4-30 is
consistent with ongoing, but slow, downgradient migration. Chloroform at TW4-29 is bounded
to the north by TW4-27 (3.2 ~-tg!L), to the east by TW4-30 (7.4 ~-tg/L), to the southeast by TW4-
35 (non-detect), to the south by TW4-34 (non-detect), and to the west by TW4-26 (8.2 ~-tg!L).
Chloroform at relatively recently installed well TW4-33 (located between TW4-4 and TW4-29)
showed a decrease in concentration, from 122 ~-tg!L to 96 ~-tg!L. Chloroform at TW4-33 is
bounded to the north by TW4-14 (6.2 ~-tg/), to the east by TW4-27 (3.2 ~-tg!L), to the west by
TW4-23 (non-detect), and to the south and west by TW4-26 (8.2 ~-tg!L). This chloroform
distribution indicates that the plume southeast of TW 4-4 is very narrow compared to more
upgradient locations.
Although changes in concentration have occurred in wells within the chloroform plume, the
boundaries of the plume have not changed significantly since the last quarter, except for a slight
expansion near TW4-16 (which is just inside the plume this quarter). The chloroform
concentration at TW4-9 increased slightly from approximately 74 ~-tg!L to 76 ~-tg/L, and remains
just within the plume. Except for the fourth quarter of 2014, TW4-9 was outside the plume prior
to the first quarter of 2016. The plume boundary remains between TW4-9 and TW4-12 (which is
non-detect for chloroform and cross-gradient of TW4-9). The increase at TW4-9 is attributable to
reduced recharge (and dilution) from the northern wildlife ponds.
Nitrate pumping generally caused the western boundary of the northern portion of the
chloroform plume to migrate to the west toward TW4-24. Since the first quarter of 2014, TW4-
24 has been both inside and outside the plume and remains outside the plume this quarter, likely
due to initiation of TW4-37 pumping in the second quarter of 2015 and reduced productivity at
TW4-24 (since the third quarter of 2014). Since the second quarter of 2014, generally increased
concentrations at TW4-6 and TW4-16 (both of which were within the chloroform plume in the
past) indicate that the plume boundary migrated to the southwest and re-incorporated both wells.
TW4-6 remains within the plume this quarter and TW4-16 (with a concentration increase from
approximately 46 ~-tg!L to 93 ~-tg!L) is again inside the plume. Increases at these wells beginning
in the second quarter of 2014 are likely related to reduced dilution from cessation of water
delivery to the northern wildlife ponds and more westerly flow induced by nitrate pumping.
However, continued operation of the nitrate pumping system is expected to enhance the capture
zone associated with the chloroform pumping system even though nitrate pumping may
redistribute chloroform within the plume and cause changes in the plume boundaries.
Furthermore, the addition of chloroform wells TW4-1, TW4-2, TW4-ll, TW4-21 and TW4-37
to the chloroform pumping network in the first half of 2015 is expected to have a beneficial
impact. Generally reduced concentrations at TW4-6 and TW4-16 after previous increases are
likely the result of initiation ofTW4-1, TW4-2, and TW4-11 pumping.
31
Continued operation of chloroform pumping wells MW-4, MW-26, TW4-19, and TW4-20 is
recommended. Pumping these wells, regardless of any short term fluctuations in concentrations
detected at the wells helps to reduce downgradient chloroform migration by removing
chloroform mass and reducing hydraulic gradients, thereby allowing natural attenuation to be
more effective. Continued operation of chloroform pumping well TW 4-4 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 [!giL in the first quarter of
2010 to 10.3 [!giL in the second quarter of 2014 is likely related to pumping at TW4-4. The
decrease in the long-term rate of water level rise at TW4-6 once TW4-4 pumping began, which
suggests that TW 4-6 is within the hydraulic influence of TW 4-4, is also consistent with the
decrease in chloroform concentrations at TW 4-6 between the first quarter of 2010 and the second
quarter of 2014. Continued operation ofTW4-1, TW4-2, TW4-11, TW4-21, and TW4-37 is also
recommended. Pumping these wells has increased overall capture and improved chloroform
mass removal rates.
Furthermore, because of the influence of TW4-4 pumping, and by analogy with the
concentration decreases at TW4-6 and TW4-26 that occurred after initiation of TW4-4 pumping,
chloroform concentrations at TW4-29 and TW4-33 are expected to eventually trend downward.
Since installation in 2013, however, concentrations at TW4-33 appear to be relatively stable,
while, since the third quarter of 2014, concentrations at TW4-29 appear to be on an upward
trend. The relatively stable chloroform at TW4-33 and recent increases in concentration at TW4-
29 suggest that chloroform migration has been arrested at TW4-33 by TW4-4 pumping and that
increasing chloroform at downgradient well TW 4-29 results from a remnant of the plume that
continues to migrate downgradient (toward TW4-30, which bounds to plume to the east). The
influence of TW 4-4 pumping at the distal end of the plume is consistent with decreasing water
levels at both TW4-29 and TW4-33. Continued evaluation of trends at TW4-29 and TW4-33 will
be provided in subsequent quarters.
EFRI and its consultants have raised the issues and potential effects associated with cessation of
water delivery to th~ northern wildlife ponds in March, 2012 during discussions with DWMRC
in March 2012 and May 2013. While past recharge from the ponds has helped limit many
constituent concentrations within the chloroform and nitrate plumes by dilution, the associated
groundwater mounding has increased hydraulic gradients and contributed to plume migration.
Since use of the northern wildlife ponds ceased in March 2012, the reduction in recharge and
decay of the associated groundwater mound are expected to increase constituent concentrations
within the plumes while reducing hydraulic gradients and rates of plume migration. Recent
increases in chloroform concentrations at TW4-6, TW4-8, TW4-9, and TW4-16 are likely related
in part to reduced dilution.
The net impact of reduced wildlife pond recharge is expected to be beneficial even though it is
also expected to result in higher concentrations that will persist until continued mass reduction
via pumping and natural attenuation ultimately reduce concentrations. Temporary increases in
chloroform concentrations are judged less important than reduced chloroform migration rates.
The actual impacts of reduced recharge on concentrations and migration rates will be defined by
continued monitoring.

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