1.0 INTRODUCTION
The Utah Department of Environmental Quality ("UDEQ") Division of Waste Management and
Radiation Control ("DWMRC") noted in a Request dated September 30, 2008 (the "Request"),
for a Voluntary Plan and Schedule to Investigate and Remediate Nitrate Contamination at the
White Mesa Uranium Mill (the "Mill") (the "Plan"), that nitrate levels have exceeded the State
water quality standard of 10 mg/L in certain monitoring wells. As a result of the Request,
Energy Fuels Resources (USA) Inc. ("EFRI") entered into a Stipulated Consent Agreement with
the Utah Water Quality Board in January 2009 which directed the preparation of a Nitrate
Contamination Investigation Report ("CIR"). A subsequent letter dated December 1, 2009,
among other things, recommended that EFRI also address elevated chloride concentrations in the
CIR. The Stipulated Consent Agreement was amended in August 2011. Under the amended
Consent Agreement ("CA"), EFRI submitted a Corrective Action Plan ("CAP"), pursuant to the
requirements of the Utah Groundwater Quality Protection Rules [UAC R317-6-6.15(C-E)] on
November 29,2011 and revised versions of the CAP on February 27,2012 and May 7, 2012. On
December 12, 2012, DWMRC signed the Stipulation and Consent Order ("SCO"), Docket
Number UGW12-04, which approved the EFRI CAP, dated May 7, 2012. The SCO ordered
EFRI to fully implement all elements of the May 7, 2012 CAP.
Based on the schedule included in the CAP and as delineated and approved by the SCO, the
activities associated with the implementation of the CAP began in January 2013. The reporting
requirements specified in the CAP and SCO are included in this quarterly nitrate report.
This is the Quarterly Nitrate Monitoring Report, as required under the SCO, State of Utah
Docket No. UGW12-04 for the fourth quarter of 2016. This report meets the requirements of the
SCO, State of UDEQ Docket No. UGW12-04 and is the document which covers nitrate
corrective action and monitoring activities during the fourth quarter of 2016.
2.0 GROUNDWATER NITRATE 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. Nitrate samples and measurements taken during this reporting period
are discussed in the remainder of this section.
2.1.1 Nitrate Monitoring
Quarterly sampling for nitrate monitoring parameters was performed in the following wells:
TWN-1
TWN-2
TWN-3
TWN-4
TWN-7
TWN-18
TW4-22*
TW4-24*
TW4-25*
Piezometer 1
Piezometer 2
Piezometer 3A **
1
As discussed in Section 2.1.2 the analytical constituents required by the CAP are inorganic
chloride and nitrate+nitrite as N (referred to as nitrate in this document)
* Wells TW4-22, TW4-24, TW4-25 are chloroform investigation wells (wells installed and
sampled primarily for the chloroform investigation) and are sampled as part of the chloroform
program. The analytical suite for these three wells includes nitrate, chloride and a select list of
Volatile Organic Compounds ("VOCs") as specified in the chloroform program. These three
wells are included here because they are being pumped as part of the remediation of the nitrate
contamination as required by the SCO and the CAP. The nitrate and chloride data are included
in this report as well as in the chloroform program quarterly report. The VOC data for these
three wells will be reported in the chloroform quarterly monitoring report only.
**Piezometer 3 was abandoned and replaced with Piezometer 3A in March 2016.
The December 12, 2012 SCO approved the CAP, which specified the cessation of sampling in
TWN-5, TWN-6, TWN-8, TWN-9, TWN-10, TWN-11, TWN-12, TWN-13, TWN-14, TWN-15,
TWN-16, TWN-17, and TWN-19. The CAP and SCO also approved the abandonment ofTWN-
5, TWN-8, TWN-9, TWN-10, TWN-11, TWN-12, TWN-13, TWN-15, and TWN-17 within 1
year of the SCO approval. These wells were abandoned in accordance with the DWMRC-
approved Well Abandonment Procedure on July 31, 2013. Wells TWN-6, TWN-14, TWN-16,
and TWN-19 have been maintained for depth to groundwater monitoring only, as noted in the
CAP.
Table 1 provides an overview of all locations sampled during the current period, along with the
date samples were collected from each location, and the date(s) upon which analytical data were
received from the contract laboratory. Table 1 also identifies rinsate samples collected, as well
as sample numbers associated with any required duplicates.
As indicated in Table 1, nitrate monitoring was performed in the nitrate monitoring wells,
chloroform wells TW4-22, TW4-24, TW4-25 and Piezometers 1, 2, and 3A. Analytical data for
all of the above-listed wells, and the piezometers, are included in Tab G.
Nitrate and chloride are also monitored in all of the Mill's groundwater monitoring wells and
chloroform investigation wells. Data from those wells for this quarter are incorporated in certain
maps and figures in this report but are discussed in their respective programmatic reports.
2.1.2 Parameters Analyzed
Locations sampled during this reporting period were analyzed for the following constituents:
• Inorganic Chloride
• Nitrate plus Nitrite as Nitrogen (referred to herein as nitrate)
Use of analytical methods consistent with the requirements found in the White Mesa Mill
Groundwater Quality Assurance Plan, ("QAP") Revision 7.2, dated June 7, 2012 was confirmed
for all analytes, as discussed later in this report.
2
2.1.3 Groundwater Head and Level Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant to Part
I.E.3 of the Groundwater Discharge Permit ("GWDP") (dated August 24, 2012):
• The quarterly groundwater compliance monitoring wells
• Existing 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, MW-22, and MW-34
• The DR piezometers that were installed during the Southwest Hydrogeologic
Investigation
• Nitrate wells TWN-1, TWN-2, TWN-3, TWN-4, TWN-6, TWN-7, TWN-14, TWN-16,
TWN-18 and TWN-19
In addition to the above, depth to water measurements are routinely observed in conjunction with
sampling events for all wells sampled during quarterly and accelerated efforts, regardless of the
sampling purpose.
All well levels used for groundwater contour mapping were measured and recorded within 5
calendar days of each other as indicated by the measurement dates in the summary sheet under
Tab C. Field data sheets for groundwater measurements are also provided in Tab C.
Weekly and monthly depth to groundwater measurements were taken in the chloroform pumping
wells MW-4, MW-26, TW4-1, TW4-2, TW4-ll, TW4-19, TW4-20, TW4-4, TW4-21, TW4-37,
TW4-39 (starting in December 2016), and the nitrate pumping wells TW4-22, TW4-24, TW4-25,
and TWN-2.
In addition, monthly water level measurements were taken in non-pumping wells MW-27, MW-
30, MW-31, TWN-1, TWN-3, TWN-4, TWN-7, and TWN-18 as required by the CAP.
2.2 Sampling Methodology and Equipment and Decontamination Procedures
The QAP provides a detailed presentation of procedures utilized for groundwater sampling
activities under the GWDP (August 24, 2012).
The sampling methodology, equipment and decontamination procedures that were performed for
the nitrate contaminant investigation, as summarized below, are consistent with the QAP.
2.2.1 Well Purging, Sampling and Depth to Groundwater
A list of the wells in order of increasing nitrate contamination is generated quarterly. The order
for purging is thus established. The list is included with the Field Data Worksheets under Tab B.
Mill personnel start purging with all of the nondetect wells and then move to the wells with
detectable nitrate concentrations, progressing from the wells having the lowest nitrate
contamination to wells with the highest nitrate contamination.
3
Before leaving the Mill office, the pump and hose are decontaminated using the cleaning agents
described in Attachment 2-2 of the QAP. Rinsate blanks are collected at a frequency of one
rinsate per 20 field samples.
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
specified in the QAP 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
2. Purging two casing volumes with stable field parameters (within 10% Relative Percent
Difference ["RPD"])
3. Purging a well to dryness and stability (within 10% RPD) of a limited list of field parameters
after recovery.
Mill personnel proceed to the first well, which is the well with the lowest concentration (i.e. non-
detect) of nitrate based on the previous quarter's sampling results. Well depth measurements are
taken and the one casing volume is calculated. The purging strategy that will be used for the
well is determined at this time based on the depth to water measurement and the previous
production of the well. The Grundfos pump (a 6 to 10 gallon per minute [gpm] pump) is then
lowered to the appropriate depth in the well and purging is started. At the first well, the purge
rate is measured for the purging event by using a calibrated 5 gallon bucket. After the
evacuation of the well has been completed, the well is sampled when possible, and the pump is
removed from the well and the process is repeated at each well location moving from the least
contaminated to most contaminated well. If sample collection is not possible due to the well
being purged dry, a sample is collected after recovery using a disposable bailer and as described
in Attachment 2-3 of the QAP. Sample collection follows the procedures described in
Attachment 2-4 of the QAP.
After the samples have been collected for a particular well, the samples are placed into a cooler
that contains ice. The well is then recapped and Mill personnel proceed to the next well. If a
bailer has been used it is disposed of.
Decontamination of non-dedicated equipment, using the reagents in Attachment 2-2 of the QAP,
is performed between each sample location, and at the beginning of each sampling day, m
addition to the pre-event decontamination described above.
2.2.2 Piezometer Sampling
Samples are collected from Piezometers 1, 2 and 3A, if possible. Samples are collected from
piezometers using a disposable bailer after one set of field measurements have been collected.
Due to the difficulty in obtaining samples from the piezometers, the purging protocols set out in
the QAP are not followed.
After samples are collected, the bailer is disposed of and samples are placed into a cooler
containing ice for sample preservation and transit to the Mill's contract analytical laboratory,
American West Analytical Laboratories ("AWAL").

2.3 Field Data
Attached under Tab B are copies of all Field Data Worksheets that were completed during the
quarter for the nitrate investigation monitoring wells and piezometers identified in Section 2.1.1
and Table 1.
2.4 Depth to Groundwater Data and Water Table Contour Map
Depth-to-groundwater measurements that were utilized for groundwater contours are included on
the Quarterly Depth to Water Sheet at Tab C of this Report along with the kriged groundwater
contour map for the current quarter generated from this data. All well levels used for
groundwater contour mapping were measured and recorded within 5 calendar days of each other
as indicated by the measurement dates in the summary sheet under Tab C. A copy of the kriged
groundwater contour map generated from the previous quarter's data is provided under Tab D.
2.5 Laboratory Results
2.5.1 Copy of Laboratory Results
The analytical results were provided by AW AL. Table 1 lists the dates when analytical results
were reported to the Quality Assurance ("QA") Manager for each well or other sample.
Analytical results for the samples collected for this quarter's nitrate investigation and a limited
list of chloroform investigation nitrate and chloride results are provided under Tab G of this
Report. Also included under Tab G are the results of analyses for duplicate samples and rinsate
samples for this sampling effort, as identified in Table 1. See the Groundwater Monitoring
Report and Chloroform Monitoring Report for this quarter for nitrate and chloroform analytical
results for the groundwater monitoring wells and chloroform investigation wells not listed in
Table 1.
2.5.2 Regulatory Framework
As discussed in Section 1.0 above, the Request, Plan, and CA each triggered a series of actions
on EFRI' s part. Potential surficial sources of nitrate and chloride have been described in the
December 30, 2009 CIR and additional investigations into potential sources were completed and
discussed with DWMRC in 2011. Pursuant to theCA, the CAP was submitted to the Director of
the Division Waste Management and Radiation Control (the "Director") on May 7, 2012. The
CAP describes activities associated with the nitrate in groundwater. The CAP was approved by
the Director on December 12, 2012. This quarterly report documents the monitoring consistent
with the program described in the CAP.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
EFRI' s QA Manager performed a QA/Quality Control ("QC") review to confirm compliance of
the monitoring program with the 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 data methods and data. Identification
5
of field QC samples collected and analyzed is provided in Section 3 .1. Discussion of adherence
to Mill sampling Standard Operating Procedures ("SOPs") is provided in Section 3.2. Analytical
completeness review results are provided in Section 3.3. The steps and tests applied to check
field data QA/QC, holding times, receipt temperature and laboratory data QA/QC are discussed
in Sections 3.4.1 through 3.4.7 below.
The analytical laboratory has provided summary reports of the analytical QA/QC measurements
necessary to maintain conformance with National Environmental Laboratory Accreditation
Conference 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 G. Results of the
review of the laboratory QA/QC information are provided under Tab H and 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 nitrate investigation program consist of one field duplicate sample for
each 20 samples, DI Field Blanks ("DIFB"), and equipment rinsate samples.
During the quarter, one duplicate sample was collected as indicated in Table 1. The duplicate
was sent blind to the analytical laboratory and analyzed for the same parameters as the nitrate
wells.
One rinsate blank sample was collected as indicated on Table 1. Rinsate samples are labeled
with the name of the subsequently purged well with a terminal letter "R" added (e.g. TWN-7R).
The field QC sample results are included with the routine analyses under Tab G.
3.2 Adherence to Mill Sampling SOPs
The QA Manager review of Mill Personnel's adherence to the existing SOPs, confirmed that the
QAIQC requirements established in the QAP and Chloroform QAP were met.
3.3 Analyte Completeness Review
All analyses required by the GWDP for nitrate monitoring for the period were performed.
3.4 Data Validation
The QAP and GWDP (August 24, 2012) identify the data validation steps and data QC checks
required for the nitrate monitoring program. Consistent with these requirements, the QA
Manager performed the following evaluations: a field data QA/QC evaluation, a holding time
evaluation, an analytical method check, a reporting limit evaluation, a QC evaluation of sample
duplicates, a QC evaluation of control limits for analysis and blanks, a receipt temperature
6
evaluation, and a rinsate evaluation. Because no VOCs are analyzed for the nitrate
contamination investigation, no trip blanks are required in the sampling program. Each
evaluation is discussed in the following sections. Data check tables indicating the results of each
test are provided under Tab H.
3.4.1 Field Data QA/QC Evaluation
The QA Manager performs a review of all field recorded parameters to assess their adherence
with QAP requirements. The assessment involved review of two sources of information: the
Field Data Sheets and the Quarterly Depth to Water summary sheet. Review of the Field Data
Sheets addresses well purging volumes and stability of five parameters: conductance, pH,
temperature, redox potential, and turbidity. Review of the Depth to Water data confirms that all
depth measurements used for development of groundwater contour maps were conducted within
a five-day period of each other. The results of this quarter's review are provided under Tab H.
Based upon the review of the field data sheets, field work was completed in compliance with the
QAP purging and field measurement requirements. A summary of the purging techniques
employed and field measurements taken is described below:
Purging Two Casing Volumes with Stable Field Parameters (within 10% RPD)
Wells TWN-01, TWN-04, and TWN-18 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 Dryne sand Stability of a Limited List of Field Parameters
Wells TWN-03 and TWN-07 were purged to dryness before two casing volumes were evacuated.
After well recovery, one set of measurements for the field parameters of pH, specific
conductivity, and water temperature only were taken; the samples were collected, and another set
of measurements for pH, specific conductivity, and water temperature were taken. Stabilization
of pH, conductivity and temperature are required within 10% RPD under the QAP. All field
parameters for this requirement were stable within 10% RPD.
Continllollsly Pumped Well
Wells TWN-02, TW4-22, TW4-24, and TW4-25 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. As previously noted, TW4-22, TW4-24, and TW4-25 are
chloroform investigation wells and are sampled under the chloroform program. Data for nitrate
and chloride are provided here for completeness purposes.
During review of the field data sheets, it was observed that sampling personnel consistently
recorded depth to water to the nearest 0.01 foot.
All field parameters for all wells were within the QAP required limits, as indicated below.
The field data collected during the quarter were in compliance with QAP requirements.
7
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 H. All samples were received and analyzed within the required
holding time.
3.4.3 Analytical Method Checklist
All analytical methods reported by the laboratory were checked against the required methods
enumerated in the QAP. Analytical method checks are provided in Tab H. All methods were
consistent with the requirements of the QAP.
3.4.4 Reporting Limit Evaluation
All analytical method reporting limits ("RLs") reported by the laboratory were checked against
the reporting limits enumerated in the QAP. Reporting Limit Checks are provided in Tab H. All
analytes were measured and reported to the required reporting limits, with the exception of
several samples that had increased repmting limits due to matrix interference or required dilution
due to the sample concentration. However, in all of those cases the analytical results were
greater than the reporting limit used.
3.4.5 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 duplicate pairs for all analytes regardless of
whether or not the reported concentrations are greater than 5 times the required detection limits.
However, data will be considered noncompliant only when the results are greater than 5 times
the required detection limit and the RPD is greater than 20%.
All duplicate results were within 20% RPD for the quarterly samples. The duplicate results are
provided under Tab H.
3.4.6 Other Laboratory QAJQC
Section 9.2 of the QAP requires that the laboratory's QNQC 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-specific required limits, or that the case narrative
8
sufficiently explains any deviation from these limits. Results of this quantitative check are
provided in Tab H.
The lab QA/QC results met these specified acceptance limits.
The QAP Section 8.1.2 requires that a Matrix Spike/Matrix Spike Duplicate ("MS/MSD") pair
be analyzed with each analytical batch. The QAP does not specify acceptance limits for the
MS/MSD pair, and the QAP does not specify that the MS/MSD pair be prepared on EFRI
samples only. Acceptance limits for MS/MSDs are set by the laboratories. The review of the
information provided by the laboratories in the data packages verified that the QAP requirement
to analyze an MS/MSD pair with each analytical batch was met. While the QAP does not require
it, the recoveries were reviewed for compliance with the laboratory established acceptance limits.
The QAP does not require this level of review, and the results of this review are provided for
information only.
The information from the Laboratory QA/QC Summary Reports indicates that the MS/MSDs
recoveries and the associated RPDs for the samples were within acceptable laboratory limits for
the regulated compounds except as indicated in Tab H. The MS/MSD recoveries that are outside
the laboratory established acceptance limits do not affect the quality or usability of the data
because recoveries above or below the acceptance limits are indicative of matrix interference.
Matrix interferences are applicable to the individual sample results only. The requirement in the
QAP to analyze a MS/MSD pair with each analytical batch was met and as such the data are
compliant with the QAP.
The information from the Laboratory QA/QC Summary Reports indicates that the Laboratory
Control Sample recoveries were acceptable, which indicate that the analytical system was
operating properly.
The QAP Section 8.1.2 requires that each analytical batch shall be accompanied by a reagent
blank. All analytical batches routinely contain a blank, which is a laboratory-grade water blank
sample made and carried through all analytical steps. For the Mill samples, a method blank is
prepared for all analytical methods. The information from the Laboratory QA/QC Summary
Reports indicates that the method blanks did not contain detections of any target analytes above
the Reporting Limit.
3.4.7 Receipt Temperature Evaluation
Chain of Custody sheets were reviewed to confirm compliance with the QAP requirement in
QAP Table 1 that samples be received at 6°C or lower. Sample temperatures checks are
provided in Tab H. All samples were received within the required temperature limit.
3.4.8 Rinsate Check
Rinsate checks are provided in Tab H. A comparison of the rinsate blank sample concentration
levels to the QAP requirements-that rinsate sample concentrations be one order of magnitude
lower than that of the actual well -indicated that all of the rinsate blank analytes met this
criterion. All rinsate and DIFB blank samples were non-detect for the quarter.

4.0 INTERPRETATIONOFDATA
4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions.
4.1.1 Current Site Groundwater Contour Map
As stated above, a listing of groundwater level readings for the current quarter (shown as depth
to groundwater in feet) is included under Tab C. The data from this tab has been interpreted
(interpolated by kriging) and plotted in a water table contour map, provided under the same tab.
The contour map is based on the current quarter's data for all wells.
The water level contour maps indicate that perched water flow ranges from generally
southwesterly beneath the Mill site and tailings cells to generally southerly along the eastern and
western margins of White Mesa south of the tailings cells. Perched water mounding associated
with the wildlife ponds locally changes the generally southerly perched water flow patterns. For
example, northeast of the Mill site, mounding associated with formerly used wildlife ponds
disrupts the generally southwesterly flow pattern, to the extent that locally northerly flow occurs
near MW -19 and PIEZ-1. The impact of the mounding associated with the northern ponds, to
which water has not been delivered since March 2012, is diminishing and is expected to continue
to diminish as the 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.
10
In general, nitrate concentrations within and adjacent to the nitrate plume appear to have been
impacted to a lesser extent than chloroform and nitrate concentrations within and in the vicinity
of the chloroform 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 nitrate and chloride within and near
the nitrate plume may occur even when the nitrate plume is under control based on the Nitrate
CAP requirements. Ongoing mechanisms that can be expected to increase the concentrations of
nitrate and chloride locally as a result of reduced wildlife pond recharge include but are not
limited to:
1) Reduced dilution -the rmxmg of low constituent concentration pond recharge into
existing perched groundwater will be reduced over time.
2) Reduced saturated thicknesses -dewatering of higher permeability zones rece1vmg
primarily low constituent concentration pond water will result in wells intercepting the
zones 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-ll); at those added during the
second quarter of 2015 (TW4-21 and TW4-37); and at TW4-39, added during the current
quarter. The overall impact was expected to be generally higher constituent concentrations in
these wells over time until mass reduction resulting from pumping and natural attenuation
eventually reduces concentrations. Short-term changes in concentrations at pumping wells and
wells adjacent to pumping wells are also expected to result from changes in pumping conditions.
In addition to changes in the flow regime caused by wildlife pond recharge, perched flow
directions are locally influenced by operation of the chloroform and nitrate pumping wells. Well
defined cones of depression are evident in the vicinity of all chloroform pumping wells except
TW4-4, TW4-37, and TW4-39. TW4-4 began pumping in the first quarter of 2010; TW4-37
began pumping during the second quarter of 2015; and TW4-39 began pumping this quarter.
Although operation of chloroform pumping well TW 4-4 has depressed the water table in the
vicinity of TW4-4, a well-defined cone of depression is not clearly evident. The lack of a well-
defined cone of depression near TW4-4likely results from 1) variable permeability conditions in
the vicinity of TW 4-4, and 2) persistent relatively low water levels at adjacent well TW 4-14. The
lack of well-defined cones of depression near TW4-37 and TW4-39 likely results from recent
start-up and close proximity to other pumping wells.
Pumping of nitrate wells TW4-22, TW4-24, TW4-25, and TWN-2 began 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, which is located up gradient of the nitrate
pumping wells.
11
Capture associated with nitrate pumping is expected to continue to increase over time as water
levels decline due to pumping and to cessation of water delivery to the northern wildlife ponds.
Interaction between nitrate and chloroform pumping is expected to enhance the capture of the
nitrate pumping system. The long term interaction between the nitrate and chloroform pumping
systems is evolving, and changes will be reflected in data collected during routine monitoring.
As discussed above, variable permeability conditions are one likely reason for the lack of a well-
defined cone of depression near chloroform pumping well TW4-4. Changes in water levels at
wells immediately south and southeast (downgradient) ofTW4-4 resulting from TW4-4 pumping
are expected to be muted because TW 4-4 is located at a transition from relatively high to
relatively low permeability conditions south and southeast of TW4-4. As will be discussed
below, the permeability of the perched zone at TW4-6 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 TW 4-4, and the permeability at TW 4-27 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 (just 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 level 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. In contrast, until the first quarter of 2016, water level trends were generally 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 appeared to be responding to past wildlife pond
recharge and continuing expansion of the groundwater mound. Since the first quarter of 2016,
however, water levels at these wells appear to be stabilizing (note: hydrographs for these wells
are provided in the quarterly Chloroform Monitoring Report).
These spatially variable water level trends likely result from pumpmg conditions, the
permeability distribution, and distance from the wildlife ponds. Wells that are relatively
hydraulically isolated (due to completion in lower permeability materials or due to intervening
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 5533.5 feet above mean sea level
["ft amsl"]), is nearly 2 feet lower than the water level at TW4-6 (approximately 5535.4 ft amsl)
12
and nearly 6 feet lower than the water level at TW4-4 (approximately 5539.2 ft amsl), even
though TW4-4 is pumping. However, water level differences among these wells are diminishing.
The static water levels at wells TW 4-14 and downgradient well TW 4-27 (installed south of
TW4-14 in the fourth quarter of 2011) were similar (within 1 to 2 feet) until the third quarter of
2014; both appeared anomalously low. The current quarterly water level at TW4-27
(approximately 5528.4 ft amsl) is approximately 5 feet lower than the water level at TW4-14
(5533.5 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 nmthem wildlife ponds. The rate of water level increase at TW4-27 is smaller than at TW4-
14 because TW 4-27 is farther downgradient of the ponds.
Prior to the installation of TW4-27, the persistently low water level at TW4-14 was considered
anomalous because it appeared to be down gradient 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 (5534.0
feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5535.4 feet amsl), and
TW4-23 (5536.9 feet amsl), as shown in the detail water level map under Tab C.
Hydraulic tests indicate that the permeability at TW4-27 is an order of magnitude lower than at
TW4-6 and three orders of magnitude lower than at TW4-4 (see Hydro Geo Chern, Inc. [HGC],
September 20, 2010: Hydraulic Testing of TW4-4, TW4-6, and TW4-26, White Mesa Uranium
Mill, July 2010; and HGC, November 28, 2011: Installation, Hydraulic Testing, and Perched
Zone Hydrogeology of Perched Monitoring Well TW4-27, White Mesa Uranium Mill Near
Blanding, Utah). Past similarity of water levels at TW4-14 and TW4-27, and the low
permeability estimate at TW4-27, suggested that both wells were completed in materials having
lower permeability than nearby wells. The low permeability condition likely reduced the rate of
long-term water level increase at TW4-14 and TW4-27 compared to nearby wells, yielding water
levels that appeared anomalously low. This behavior is consistent with hydraulic test data
collected from 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: HGC, January 23, 2014, Contamination
Investigation Report, TW4-12 and TW4-27 Areas, White Mesa Uranium Mill Near Blanding,
Utah; and HGC, July 1, 2014, Installation and Hydraulic Testing of TW4-35 and TW4-36,
White Mesa Uranium Mill Near Blanding, Utah [As-Built Report]). Hydraulic tests also indicate
that the permeability at TW 4-36 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.
4.1.2 Comparison of Current Groundwater Contour Map to Groundwater Contour Map
for Previous Quarter
The groundwater contour maps for the Mill site for the previous quarter, as submitted with the
Nitrate Monitoring Report for the previous quarter, are attached under Tab D. Small (<1 foot)
changes in water levels were reported at the majority of site wells; water levels and water level
13
contours for the site have not changed significantly since the last quarter except for a few
locations.
A comparison of the water table contour maps for the current quarter (fourth quarter of 2016) to
the water table contour maps for the previous quarter (third 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. Nor is a significant cone of depression yet evident at TW4-39 which
began pumping this quarter.
Drawdowns at chloroform pumping wells MW-26, TW4-1, TW4-2 and nitrate pumping well
TW4-22 decreased by more than 2 feet this quarter, with the drawdown at TW4-22 decreasing by
more than 20 feet. The change at TW4-22 partially compensated for the 26 foot increase in
drawdown last quarter. The drawdown in nitrate pumping well TW4-24 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 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 smaller than
last quarter due to the relatively large decrease in drawdown at TW4-22 and decreases in
drawdown at TW4-1 and TW4-2.
As discussed in Section 4.1.1, pumping at chloroform well TW 4-4, which began in the first
quarter of 2010, has depressed the water table near TW4-4, but a well-defined cone of depression
is not clearly evident, likely due to variable permeability conditions near TW4-4 and the
persistently low water level at adjacent well TW 4-14.
Reported water level decreases of up to 0.4 feet at Piezometers 2, 4, and 5, and at 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 0.34 feet at both piezometers 4 and 5 may also
result from reduced recharge at the southern wildlife pond. Reported water level increases of
approximately 0.41 feet and 0.59 feet at Piezometers 1 and 3A, respectively, may indicate a
slowing in the decay of the groundwater mound.
The reported water level at MW-20 decreased by approximately 3.8 feet, and the water level at
MW-37 increased by approximately 2.4 feet, respectively. Water level variability at MW-20 and
MW -37 likely results from low permeability and variable intervals between purging/sampling
and water level measurement.
14
Measurable water was not reported at DR-22. Although DR-22 is typically dry, measurable
water was reported in the bottom of its casing between the second quarter of 2015 and last
quarter.
4.1.3 Hydrographs
Attached under Tab E are hydrographs showing groundwater elevation in each nitrate
contaminant investigation monitor well over time. Per the CAP, nitrate wells TWN-6, TWN-14,
TWN-16, and TWN-19 have been maintained for depth to groundwater monitoring only. These
hydrographs are also included in Tab E.
4.1.4 Depth to Groundwater Measured and Groundwater Elevation
Attached in 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.
4.2 Effectiveness of Hydraulic Containment and Capture
4.2.1 Hydraulic Containment and Control
The CAP states that hydraulic containment and control will be evaluated in part based on water
level data and in part on concentrations in wells downgradient of pumping wells TW4-22 and
TW4-24.
As per the CAP, the fourth quarter of 2013 was the first quarter that hydraulic capture associated
with nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 was evaluated. Hydraulic
containment and control based on water level data is considered successful per the CAP if the
entire nitrate plume upgradient of TW4-22 and TW4-24 falls within the combined capture of the
nitrate pumping wells. Capture zones based on water level contours calculated by kriging the
current quarter's water level data are provided on water level contour maps included under Tab
C. The nitrate capture zones are defined by the bounding stream tubes associated with nitrate
pumping wells. Each bounding stream tube represents a flow line parallel to the hydraulic
gradient and therefore perpendicular to the intersected water level contours. Assuming that the
stream tubes do not change over time, all flow between the bounding stream tubes associated
with a particular pumping well is presumed to eventually reach and be removed by that well.
Capture associated with chloroform pumping wells is also included on these maps because the
influence of the chloroform and nitrate pumping systems overlap.
The specific methodology for calculating the nitrate capture zones is substantially the same as
that used since the fourth quarter of 2005 to calculate the capture zones for the chloroform
program, as agreed to by the DWMRC and EFRI. The procedure for calculating nitrate capture
zones is as follows:
1) Calculate water level contours by gridding the water level data on approximately 50-foot
centers using the ordinary linear kriging method in Surfer™. Default kriging parameters
are used that include a linear variogram, an isotropic data search, and all the available
water level data for the quarter, including relevant seep and spring elevations.
15
2) Calculate the capture zones by hand from the kriged water level contours following the
rules for flow nets:
-from each pumping well, reverse track the stream tubes that bound the capture zone of
each well,
-maintain perpendicularity between each stream tube and the kriged water level contours.
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-4, TW4-4, TW4-
11, TW4-20, TW4-21, and TW4-37 decreased by approximately 0.3, 1.2, 0.03, 0.5, 0.4, and 1.1
feet, respectively, while the water levels in chloroform pumping wells MW-26, TW4-1, TW4-2,
and TW4-19 increased by approximately 3.3, 8.7, 3.7, and 0.03 feet, respectively. The water
levels in nitrate pumping wells TW4-24 and TW4-25 each decreased by approximately 2 feet,
while the water levels in nitrate pumping wells TW4-22 and TWN-2 increased by approximately
20.5 and 1.3 feet, respectively. Overall, the apparent capture of the combined pumping systems
has decreased compared to last quarter, primarily due to the relatively large decrease in
drawdown at TW4-22 and decreases in drawdown at TW4-1 and TW4-2.
The capture associated with nitrate pumping wells and chloroform pumping wells added in 2015
and this quarter is expected to increase over time as water levels continue to decline due to
pumping and to cessation of water delivery to the northern wildlife ponds. Slow development of
hydraulic capture is consistent with and expected based on the relatively low permeability of the
perched zone at the site. Furthermore, the presence of the perched groundwater mound, and the
apparently anomalously low water level at TWN-7, will influence the definition of capture
associated with the nitrate pumping system.
That pumping is likely sufficient to eventually capture the entire plume upgradient of TW4-22
and TW4-24 can be demonstrated by comparing the combined average pumping rates of all
nitrate pumping wells for the current quarter to estimates of pre-pumping flow through the nitrate
plume near the locations of TW4-22 and TW4-24. The pre-pumping flow calculation presented
from the fourth quarter of 2013 through the second quarter of 2015 was assumed to represent a
steady state 'background' condition that included constant recharge, hydraulic gradients, and
saturated thicknesses; the calculation did not account for reduced recharge and saturated
thickness caused by cessation of water delivery to the northern wildlife ponds since March, 2012.
Because significant water level declines have occurred in upgradient portions of the nitrate
plume due to reduced recharge, hydraulic gradients within the plume have been reduced
independent of pumping. Changes related to reduced wildlife pond recharge have also resulted in
reduced well productivity. Generally reduced productivities of nitrate pumping well TW4-24 and
chloroform pumping well TW 4-19 since the third quarter of 2014 are at least partly the result of
reduced recharge.
The pre-pumping flow through the nitrate plume near TW4-22 and TW4-24 that was presented
from the fourth quarter of 2013 through the second quarter of 2015 was estimated using Darcy's
Law to lie within a range of approximately 1.31 gpm to 2.79 gpm. Calculations were based on an
average hydraulic conductivity range of 0.15 feet per day (ft/day) to 0.32 ft/day (depending on
the calculation method), a pre-pumping hydraulic gradient of 0.025 feet per foot (ft/ft), a plume
width of 1,200 feet, and a saturated thickness (at TW4-22 and TW4-24) of 56 feet. The hydraulic
conductivity range was estimated by averaging the results obtained from slug test data that were
16
collected automatically by data loggers from wells within the plume and analyzed using the KGS
unconfined slug test solution available in Aqtesolve™ (see Hydro Geo Chern, Inc. [HGC],
August 3, 2005: Perched Monitoring Well Installation and Testing at the White Mesa Uranium
Mill, April Through June 2005; HGC, March 10, 2009: Perched Nitrate Monitoring Well
Installation and Hydraulic Testing, White Mesa Uranium Mill; and HGC, March 17 2009: Letter
Report to David Frydenlund, Esq, regarding installation and testing of TW4-23, TW4-24, and
TW4-25). These results are summarized in Table 6. Data from fourth quarter 2012 were used to
estimate the pre-pumping hydraulic gradient and saturated thickness. These data are summarized
in Tables 7 and 8.
The average hydraulic conductivity was estimated to lie within a range of 0.15 ft/day to 0.32
ft/day. Averages were calculated four ways. As shown in Table 6 arithmetic and geometric
averages for wells MW-30, MW-31, TW4-22, TW4-24, TW4-25, TWN-2, and TWN-3 were
calculated as 0.22 and 0.15 ft/day, respectively. Arithmetic and geometric averages for a subset
of these wells (MW-30, MW-31, TW4-22, and TW4-24) were calculated as 0.32 and 0.31 ft/day,
respectively. The lowest value, 0.15 ft/day, represented the geometric average of the hydraulic
conductivity estimates for all the plume wells. The highest value, 0.32 ft/day, represented the
arithmetic average for the four plume wells having the highest hydraulic conductivity estimates
(MW-30, MW-31, TW4-22, and TW4-24).
Pre-pumping hydraulic gradients were estimated at two locations; between TW4-25 and MW-31
(estimated as 0.023 ft/ft), and between TWN-2 and MW-30 (estimated as 0.027 ft/ft). These
results were averaged to yield the value used in the calculation (0.025 ft/ft). The pre-pumping
saturated thickness of 56 feet was an average of pre-pumping saturated thicknesses at TW4-22
and TW4-24.
As discussed above the hydraulic gradient and saturated thickness used in the pre-pumping
calculations were assumed to represent a steady state 'background' condition that was
inconsistent with the cessation of water delivery to the northern wildlife ponds, located
upgradient of the nitrate plume. Hydraulic gradients and saturated thicknesses within the plume
have declined since nitrate pumping began as a result of two factors: reduced recharge from the
ponds, and the effects of nitrate pumping. A more representative 'background' flow condition
that accounts for reduced wildlife pond recharge was presented in Attachment N (Tab N) of the
third quarter 2015 Nitrate Monitoring report. The original pre-pumping 'background' flow range
of 1.31 gpm to 2.79 gpm has been recalculated to range from 0.79 gpm to 1.67 gpm, as presented
in Table 9. This calculation is still considered conservative because the high end of the range
assumed an arithmetic average hydraulic conductivity of a subset of plume wells having the
highest conductivities.
The cumulative volume of water removed by nitrate pumping wells TW4-22, TW4-24, TW4-25,
and TWN-2 during the current quarter was approximately 266,491 gallons. This equates to an
average total extraction rate of approximately 2.06 gpm over the 90 day quarter. This average is
similar to but larger than last quarter's average of approximately 1.7 gpm and accounts for time
periods when pumps were off due to insufficient water columns in the wells. The current
quarter's pumping (2.06 gpm) exceeds the high end of the recalculated 'background' flow range
by approximately 0.39 gpm, or a factor of 1.2.
17
Although TW4-22, TW4-24, TW4-25, and TWN-2 are designated nitrate pumping wells, some
chloroform pumping wells are also located within the nitrate plume because the northwest
portion of the chloroform plume commingles with the central portion of the nitrate plume. While
chloroform pumping wells TW4-19 and TW4-20 are only periodically within the nitrate plume,
chloroform pumping wells TW4-21 and TW4-37 have been within the nitrate plume consistently
since they started pumping in 2015. The volume of water removed by TW4-21, TW4-22, TW4-
24, TW4-25, TW4-37, and TWN-2 this quarter is approximately 498,752 gallons, or
approximately 3.85 gpm over the 90 day quarter, which exceeds the high end of the recalculated
'background' flow range by approximately 2.2 gpm, or a factor of 2.3.
Because the arithmetic average hydraulic conductivity of a subset of plume wells having the
highest conductivities was used to calculate the high end of the 'background' flow range, the
high end is considered less representative of actual conditions than using the geometric average
conductivity of all of the plume wells. Therefore, nitrate pumping likely exceeds the actual flow
through the plume by more than factors ranging from 1.2 to 2.3 as calculated above. Nitrate
pumping is therefore considered adequate at the present time even with reduced productivity at
TW4-24.
The CAP states that MW-5, MW-11, MW-30, and MW-31 are located downgradient of TW4-22
and TW4-24. MW-30 and MW-31 are within the plume near its downgradient edge and MW-5
and MW -11 are outside and downgradient of the plume. Per the CAP, hydraulic control based on
concentration data will be considered successful if the nitrate concentrations in MW-30 and
MW-31 remain stable or decline, and the nitrate concentrations in downgradient wells MW-5
and MW -11 do not exceed the 10 mg/L standard.
Table 5 presents the nitrate concentration data for MW-30, MW-31, MW-5 and MW-11, which
are down-gradient of pumping wells TW4-22 and TW4-24. Based on these concentration data,
the nitrate plume is under control.
The nitrate plume has not migrated downgradient to MW-5 or MW-11; nitrate was not detected
at MW-11 and was detected at MW-5 at a concentration of approximately 0.24 mg/L this
quarter. Between the previous and current quarters, nitrate concentrations decreased slightly in
both MW-30 and MW-31. Nitrate in MW-30 decreased from 18 mg/L to 17.2 mg/L and nitrate
in MW-31 decreased from 19.7 mg/L to 18.8 mg/L. Although short-term fluctuations have
occurred, nitrate concentrations in MW-30 and MW-31 have been relatively stable,
demonstrating that plume migration is minimal or absent.
Chloride has been relatively stable at MW-30 but is generally increasing at MW-31 (see Tab J
and Tab K, discussed in Section 4.2.4). The apparent increase in chloride and relatively stable
nitrate at MW -31 suggests a natural attenuation process that is affecting nitrate but not chloride.
A likely process that would degrade nitrate but leave chloride unaffected is reduction of nitrate
by pyrite. The likelihood of this process in the perched zone is discussed in HGC, December 7
2012; Investigation of Pyrite in the Perched Zone, White Mesa Uranium Mill Site, Blanding,
Utah.
4.2.2 Current Nitrate and Chloride Isoconcentration Maps
18
Included under Tab I of this Report are current nitrate and chloride iso-concentration maps for
the Mill site. Nitrate iso-contours start at 5 mg/L and chloride iso-contours start at 100 mg/L
because those values appear to separate the plumes from background. All nitrate and chloride
data used to develop these iso-concentration maps are from the current quarter's sampling
events.
4.2.3 Comparison of Areal Extent
The area of the nitrate plume is slightly larger than last quarter due to a 'spur' in the plume
extending from the vicinity of chloroform pumping well TW4-19 to the vicinity of TW4-10,
caused by the addition of new chloroform well TW4-39, which has a nitrate concentration of
approximately 21 mg/L.
TW4-18 remained outside the plume with a concentration of approximately 5 mg/L. TW4-18
was encompassed by an eastward-extending 'spur' in the plume during the third quarter of 2015,
similar to an occurrence during the third quarter of 2013. Changes in nitrate concentrations near
TW 4-18 are expected to result from changes in pumping and from the cessation of water
delivery to the northern wildlife ponds. The reduction in low-nitrate recharge from the ponds
appeared to be having the anticipated effect of generally increased nitrate concentrations in some
wells downgradient of the ponds.
However, decreasing to relatively stable nitrate concentrations at most wells in the vicinity of
TW 4-18 between the first quarter of 2014 and the second quarter of 2015 after previous
increases suggested that conditions in this area had stabilized. Since the second quarter of 2015,
concentrations at TW4-18 have been above and below 10 mg/L, but have remained below 10
mg/L since the third quarter of 2015. Over this same time period, concentrations at nearby wells
TW4-3 and TW4-9 remained below 10 mg/L, concentrations at TW4-5 exceeded 10 mg/L only
once (first quarter of2016), and concentrations at TW4-10 remained above 10 mg/L.
Although increases in concentration in the area downgradient of the wildlife ponds have been
anticipated as the result of reduced dilution, the magnitude and timing of the increases are
difficult to predict due to the measured variations in hydraulic conductivity at the site and other
factors. Nitrate in the area directly downgradient (south to south-southwest) of the northern
wildlife ponds is associated with the chloroform plume, is cross-gradient of the nitrate plume as
defined in the CAP, and is within the capture zone of the chloroform pumping system. Perched
water flow in the area is to the southwest in the same approximate direction as the main body of
the nitrate plume.
Nitrate concentrations at the downgradient edge of the plume (MW-30 and MW-31) have been
relatively stable, demonstrating that nitrate plume migration is minimal or absent. As discussed
in Section 4.2.1, stable nitrate at MW-30 and MW-31 is consistent with a natural attenuation
process affecting nitrate but not chloride, as elevated chloride associated with the nitrate plume
continues to migrate downgradient.
With regard to chloroform, changes in the boundary of the chloroform plume are attributable in
pa1t to the initiation of nitrate pumping. Once nitrate pumping started, the boundary of the
chloroform plume migrated to the west toward nitrate pumping well TW4-24, and then to the
southwest to reincorporate chloroform monitoring wells TW 4-6 and TW 4-16. Concentration
increases leading to the reincorporation of these wells occurred first at TW 4-24, then at TW 4-16
and TW4-6. Subsequent contraction of the plume eastward away from TW4-24 and TW4-16
19
through the first quarter of 2016 is attributable in part to the start-up of additional chloroform
pumping wells during the first half of 2015, and reduced productivity at TW4-24. More details
regarding the chloroform data and interpretation are included in the Quarterly Chloroform
Monitoring Report submitted under separate cover.
4.2.4 Nitrate and Chloride Concentration Trend Data and Graphs
Attached under Tab J is a table summarizing values for nitrate and chloride for each well over
time.
Attached under Tab K are graphs showing nitrate and chloride concentration plots in each
monitor well over time.
4.2.5 Interpretation of Analytical Data
Comparing the nitrate analytical results to those of the previous quarter, as summarized in the
tables included under Tab J, the following observations can be made for wells within and
immediately surrounding the nitrate plume:
a) Nitrate concentrations have increased by more than 20% m the following wells
compared to last quarter: TW4-16;
b) Nitrate concentrations have decreased by more than 20% in the following wells
compared to last quarter: TW4-25 and TW4-37;
c) Nitrate concentrations have remained within 20% in the following wells compared to
last quarter: MW-26, MW-27, MW-30, MW-31, TW4-3, TW4-5, TW4-9, TW4-10,
TW4-11, TW4-18, TW4-19, TW4-20, TW4-21, TW4-22, TW4-24, TWN-1, TWN-2,
TWN-3, TWN-4, and TWN-7;
d) MW-11, MW-25 and MW-32 remained non-detect;
e) TWN-18 increased from non-detect to approximately 0.5 mg/L; and
f) New wells TW4-38 and TW4-39 have initial concentrations of approximately 11 and 21
mg/L, respectively.
As indicated, nitrate concentrations for many of the wells with detected nitrate were within 20%
of the values reported during the previous quarter, suggesting that variations are within the range
typical for sampling and analytical error. The remaining wells had changes in concentration
greater than 20%. The latter includes chloroform pumping well TW4-37; nitrate pumping well
TW4-25; and non-pumping well TW4-16. Concentrations at TW4-16 and TW4-25 are less than
3 mg/L.
TW4-16 is adjacent to chloroform pumping wells MW-26 and TW4-ll. Fluctuations in
concentrations at pumping wells and wells adjacent to pumping wells likely result in part from
the effects of pumping as discussed in Section 4.1.1.
20
The nitrate concentration in new chloroform pumping well TW4-39 was approximately 21 mg/L.
Concentrations in chloroform pumping well TW4-19 and non-pumping well TW4-10 that were
greater than or equal to 10 mg/L (10 mg/L and 14.8 mg/L, respectively) caused a southeast
trending 'spur' in the plume to extend from the vicinity of TW4-19 to the vicinity of TW4-10,
incorporating TW4-39. MW-27, located west of TWN-2, and TWN-18, located north of TWN-
3, bound the nitrate plume to the west and north (See Figure I-1 under Tab I). In addition, the
southernmost (downgradient) boundary of the plume remains between MW-30/MW-31 and
MW-5/MW-11. Nitrate concentrations at MW-5 (adjacent to MW-11) and MW-11 have
historically been low(< 1 mg/L) or non-detect for nitrate (See Table 5). Non-detectable nitrate at
MW -11 is consistent with the relative stability of the downgradient margin of the plume. MW-
25, MW-26, MW-32, TW4-3, TW4-5, TW4-9, TW4-11, TW4-16, TW4-18, TW4-25, TWN-1,
and TWN-4 bound the nitrate plume to the east.
Nitrate concentrations outside the nitrate plume are greater than 10 mg!L at a few locations:
TW4-10 (14.8 mg/L), TW4-12 (25.8 mg/L), TW4-26 (15 mg/L), TW4-27 (19.3 mg/L), TW4-28
(25.5 mg/L), and new well TW4-38 (11.2 mg/L). Concentrations at TW4-18 are also
occasionally above 10 mg/L. Each of these wells is located southeast of the nitrate plume as
defined in the CAP and is separated from the plume by a well or wells having nitrate
concentrations that are either non-detect, or, if detected, are less than 10 mg!L. Concentrations at
TW4-10, TW4-26, TW4-27 and TW4-28 are within 20% of last quarter's concentrations while
the concentration at TW4-12 decreased by more than 20%.
Since 2010, nitrate concentrations at TW 4-10 and TW 4-18 have been above and below 10 mg/L
Concentrations were below 10 mg/L between the first quarter of 2011 and second quarter of
2013, and mostly close to or above 10 mg/L between the second quarter of 2013 and third
quarter of 2015. However, concentrations at TW4-18 have been below 10 mg!L over the last four
quarters. Since 2010, concentrations at nearby well TW4-5 have exceeded 10 mg/L only twice,
and concentrations at nearby wells TW4-3 and TW4-9 have remained below 10 mg/L. Nitrate at
TW4-5, TW4-10, and TW4-18 is associated with the chloroform plume, and is within the capture
zone of the chloroform pumping system. Elevated nitrate at TW4-12, TW4-26, TW4-27, TW4-
28, and new well TW4-38 is likely related to former cattle ranching operations at the site.
Chloride concentrations are measured because elevated chloride (greater than 100 mg/L) is
associated with the nitrate plume. Chloride concentrations at all sampled locations this quarter
are within 20% of their respective concentrations during the previous quarter except at non-
pumping well TWN-18, in which chloride increased from approximately 53 mg/L to
approximately 67 mg/L. This change likely results from its position near the upgradient margin
of the plume.
Piezometer Piez-3A was installed in the second quarter of 2016 as a replacement to piezometer
PIEZ-3. The chloride concentration at piezometer PIEZ-3A (100 mg/L) was approximately three
times higher this quarter than the pre-abandonment first quarter 2016 concentration at PIEZ-3
(approximately 33 mg/L). The nitrate concentration at PIEZ-3A (approximately 8.4 mg/L) was
also higher this quarter than the pre-abandonment first quarter 2016 PIEZ-3 concentration
(approximately 2.2 mg/L).
21
4.3 Estimation of Pumped Nitrate Mass and Residual Nitrate Mass within the Plume
Nitrate mass removed by pumping is summarized in Table 2, and includes mass removed by both
chloroform and nitrate pumping wells. Table 3 shows the volume of water pumped at each well
and Table 4 provides the details of the nitrate removal for each well. Mass removal calculations
begin with the third quarter of 2010 because the second quarter, 2010 data were specified to be
used to establish a baseline mass for the nitrate plume. As stated in the CAP, the baseline mass is
to be calculated using the second quarter, 2010 concentration and saturated thickness data
"within the area of the kriged 10 mg/L plume boundary." The second quarter, 2010 data set was
considered appropriate because "the second quarter, 2010 concentration peak at TWN-2 likely
identifies a high concentration zone that still exists but has migrated away from the immediate
vicinity of TWN-2."
As shown in Table 2, a total of approximately 2,008 lb of nitrate has been removed from the
perched zone since the third quarter of 2010. Prior to the first quarter of 2013, all direct nitrate
mass removal resulted from operation of chloroform pumping wells MW-4, MW-26, TW4-4,
TW4-19, and TW4-20. During the current quarter:
• A total of approximately 106 lb of nitrate was removed by the chloroform pumping wells
and by nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2.
• Of the 106 lb removed during the current quarter, approximately 52 lb, (or 49 %), was
removed by the nitrate pumping wells.
The calculated nitrate mass removed was slightly higher than last quarter's approximately 101
lbs.
As discussed in Section 4.3.1, achievable pumping rates are expected to diminish over time as
saturated thicknesses are reduced by pumping and by cessation of water delivery to the northern
wildlife ponds. Attachment N (Tab N) of the third quarter 2015 Nitrate Monitoring report
provides an evaluation of reduced productivity at chloroform pumping well TW4-19 and nitrate
pumping well TW4-24.
Baseline mass and current quarter mass estimates (nitrate + nitrite as N) for the nitrate plume are
approximately 43,700 lb and 31,800 lb , respectively. Mas e timate were calculated within the
plume boundarie a defined by the k:riged lO mg/L i. ·ocon by 1) gridding (kriging) the nitrate
concentration data on 50-foot centers; 2) calculating the volume of water in each grid cell based
on the saturated thickness and assuming a porosity of 0.18· 3) calculating the rna s of
nitrate+nitrite as N in each cell based on the concentration and volume of water for each cell; and
4) totaling the mass of all grid cells within the 10 mg!L plume boundary. Data used in these
calculations included data from wells listed in Table 3 of the CAP.
The nitrate mass estimate for the current quarter is lower than the baseline estimate by
approximately 11,900 lb, and this difference is greater than the amount of nitrate mass removed
dh'ectly by pumping. Changes in the quarterly mass estimates are expected to result primarily
from 1) nitrate mass removed directly by pumping, 2) natural attenuation of nitrate, and 3)
changes in nitrate concentrations in wells within the plume as a result of re-distribution of nitrate
within the plume and changes in saturated thicknesses. Redistribution of nitrate within the plume
22
and changes in saturated thicknesses will be impacted by changes in pumping and in background
conditions such as the decay of the perched water mound associated with the northern wildlife
ponds. Cessation of water delivery to the northern wildlife ponds is expected to result in reduced
saturated thicknesses and reduced dilution, which in turn is expected to result in increases in
concentrations.
The mass estimate during the current quarter (31 ,800 lb) was smaller than the mass estimate
during the previous quarter (32,230 lb) by 430 lb or approximately 1.3 %. This difference is
attributable to slightly lower average nitrate concentrations within the plume which offset the
slightly increased plume area resulting from the 'spur' extending southeast from TW4-19 to
TW 4-10 this quarter.
Nitrate mass removal by pumping and natural attenuation (expected to result primarily from
pyrite oxidation/nitrate reduction) act to lower nitrate mass within the plume. Changes resulting
from redistribution of nitrate within the plume are expected to result in both increases and
decreases in concentrations at wells within the plume and therefore increases and decreases in
mass estimates based on those concentrations, thus generating 'noise' in the mass estimates.
Furthermore, because the sum of sampling and analytical error is typically about 20%, changes
in the mass estimates from quarter to quarter of up to 20% could result from typical sampling
and analytical error alone. Only longer-term analyses of the mass estimates that minimize the
impacts of these quarter to quarter variations will provide useful information on plume mass
trends. Over the long term, nitrate mass estimates are expected to trend downward as a result of
direct removal by pumping and through natural attenuation.
As specified in the CAP, once eight quarters of data were collected (starting with the first quarter
of 2013), a regression trend line was to be applied to the quarterly mass estimates and evaluated.
The trend line was to be updated quarterly and reevaluated as additional quarters of data were
collected. The evaluation was to determine whether the mass estimates were increasing,
decreasing, or stable.
As the fourth quarter of 2014 constituted the eighth quarter as specified in the CAP, the mass
estimates were plotted, and a regression line was fitted to the data and evaluated. The regression
line has been updated each quarter since the fourth quarter of 2014 as shown in Figure M.1 of
Tab M. The fitted line shows a decreasing trend in the mass estimates.
5.0 LONG TERM PUMP TEST AT TWN-02, TW4-22, TW4-24, and TW4-
25 OPERATIONS REPORT
5.1 Introduction
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 SCO dated December 12,
2012.
In addition, as a part of the investigation of chloroform contamination at the Mill site, EFRI has
been conducting a Long Term Pump Test on MW-4, TW4-19, MW-26, and TW4-20, and, since
January 31, 2010, TW4-4. In anticipation of the final approval of the GCAP, beginning on
23
January 14, 2015, EFRI began long term pumping of TW4-1, TW4-2, and TW4-11 and began
long term pumping of TW4-21 and TW4-37 on June 9, 2015. 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.
Because wells MW-4, TW4-19, MW-26, TW4-4, TW4-20, TW4-01, TW4-02, TW4-11, TW4-
21, TW4-37, and TW4-39 are pumping wells that may impact the removal of nitrate, they are
included in this report and any nitrate removal realized as part of this pumping is calculated and
included in the quarterly reports.
The following information documents the operational activities during the quarter.
5.2 Pumping Well Data Collection
Data collected during the quarter included the following:
• Measurement of water levels at MW-4, TW4-19, MW-26, and TW4-20 and,
commencing regularly on March 1, 2010, TW4-4, on a weekly basis,
• Measurement of water levels weekly at TW4-22, TW4-24, TW4-25, and TWN-02

other constituents
5.3 Water Level Measurements
Beginning August 16, 2003, water level measurements from chloroform pumping wells MW-4,
MW-26, and TW4-19 were conducted weekly. From commencement of pumping TW4-20, and
regularly after March 1, 2010 for TW4-4, water levels in these two chloroform pumping wells
have been measured weekly. From commencement of pumping in January 2013, water levels in
wells TW4-22, TW4-24, TW4-25, and TWN-02 have been measured weekly. From the
commencement of pumping in December 2016, water levels in TW4-39 have been measured.
Copies of the weekly Depth to Water monitoring sheets for MW-4, MW-26, TW4-19, TW4-20,
TW4-4, TW4-22, TW4-24, TW4-25, TWN-02, TW4-01, TW4-02, TW4-11, TW4-21, TW4-37,
and TW4-39 are included under Tab C.
24
Monthly depth to water monitoring is required for all of the chloroform contaminant
investigation wells and non-pumping wells MW-27, MW-30, MW-31, TWN-1, TWN-3, TWN-
4, TWN-7, and TWN-18. Copies of the monthly depth to Water monitoring sheets are included
under Tab C.
5.4 Pumping Rates and Volumes
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 either transferred to the Cell 1 evaporation pond or is used in the Mill process.
The pumped wells are fitted with a flow meter which records the volume of water pumped from
the well in gallons. The flow meter readings shown in Tab C are used to calculate the gallons of
water pumped from the wells each quarter as required by Section 7.2.2 of the CAP. The average
pumping rates and quarterly volumes for each of the pumping wells are shown in Table 3. The
cumulative volume of water pumped from each of the wells is shown in Table 4.
On November 15, 2016, all of the heat lamps for the pumping wells were turned on for the
winter months. Other operational notations made by the field staff are summarized below.
5.4.1 TW4-19
On October 5, 2016, Mill Field Personnel noted during the routine weekly inspection that the
TW 4-19 had no power and was not operating. Mill Maintenance Personnel were notified and
stated that the circuit breaker had tripped. The breaker was turned on and the well pumped with
no additional issues noted. No official notifications to DWMRC were required as the issue was
rectified within 24-hours.
5.4.2 TW 4-04
On October 31, 2016, Mill Field Personnel noted during the routine weekly inspection that the
flow meter on TW4-04 was malfunctioning. The flow meter was replaced. No official
notifications to DWMRC were required as the issue was rectified within 24-hours and there was
no loss of pumping.
On November 9, 2016, Mill Field Personnel noted during the routine weekly inspection that the
pump on TW 4-04 was not functioning. Mill Maintenance Personnel were notified and the pump
was replaced. No official notifications to DWMRC were required as the issue was rectified
within 24-hours.

On December 27, 2016, Mill Field Personnel noted during the routine weekly inspection that the
heat lamp on TW4-21 had burned out. The lamp was replaced.
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 were no corrective actions required during the previous quarters' monitoring period.
7.0 CONCLUSIONS AND RECOMMENDATIONS
As per the CAP, the current quarter is the thirteenth quarter that hydraulic capture associated
with nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 was evaluated. The
apparent combined capture of the nitrate and chloroform pumping systems is slightly smaller
than last quarter. Capture associated with nitrate pumping wells is expected to increase over time
as water levels decline due to pumping and to cessation of water delivery to the northern wildlife
ponds. Furthermore, the evaluation of the long term interaction between nitrate and chloroform
pumping systems requires more data to be collected as part of routine monitoring. Slow
development of hydraulic capture by the nitrate pumping system is consistent with and expected
based on the relatively low permeability of the perched zone at the site. Definition of capture
associated with the nitrate pumping system is also influenced by the perched groundwater mound
and the apparently anomalously low water level at TWN-7.
Nitrate pumping is likely sufficient to eventually capture the entire nitrate plume upgradient of
TW4-22 and TW4-24 even with reduced productivity at TW4-24. Hydraulic gradients and
saturated thicknesses within the plume have declined since nitrate pumping began as a result of
two factors: reduced recharge from the ponds, and the effects of nitrate pumping. A more
representative 'background' flow condition that accounts for reduced wildlife pond recharge was
presented in Attachment N (Tab N) of the third quarter, 2015 Nitrate Monitoring report. The
original pre-pumping 'background' flow range of 1.31 gpm to 2.79 gpm was recalculated to
range from 0.79 gpm to 1.67 gpm. This calculation is still considered conservative because the
high end of the calculated range assumed an arithmetic average hydraulic conductivity of a
subset of plume wells having the highest conductivities. The current nitrate pumping of
approximately 2.06 gpm, based on water removed by TW4-22, TW4-24, TW4-25, and TWN-2,
exceeds the high end of the recalculated 'background' range by 0.36 gpm, or a factor of
approximately 1.2. If water removed by chloroform pumping wells TW4-21 and TW4-37 is
included, the current nitrate pumping of approximately 3.85 gpm exceeds the high end of the
recalculated 'background' range by 2.2 gpm, or a factor of approximately 2.3. Including TW4-21
and TW4-37 is appropriate because these wells have been within the nitrate plume consistently
since they started pumping in 2015.
26
In addition, because the arithmetic average hydraulic conductivity of a subset of plume wells
having the highest conductivities was used in recalculating the high end of the 'background' flow
range, the high end is considered less representative of actual conditions than using the
geometric average conductivity of all of the plume wells. Therefore, nitrate pumping likely
exceeds flow through the plume by factors greater than 1.2 to 2.3 times the high end of the
recalculated range. Nitrate pumping is considered adequate at the present time even with reduced
productivity at TW4-24. Furthermore, as the groundwater mound associated with former water
delivery to the northern wildlife ponds continues to decay, hydraulic gradients and saturated
thicknesses will continue to decrease, and 'background' flow will be proportionally reduced,
thereby reducing the amount of pumping needed.
Fourth quarter, 2016 nitrate concentrations at many of the wells within and adjacent to the nitrate
plume 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 chloroform pumping well TW4-37; nitrate pumping
well TW4-25; and non-pumping well TW4-16. Concentrations at TW4-16 and TW4-25 are less
than 3 mg/L. TW4-16 is adjacent to chloroform pumping wells MW-26 and TW4-11.
Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells likely
result in part from the effects of pumping as discussed in Section 4.1.1. The nitrate
concentrations in wells MW -25 and MW -32 remained non-detect.
As discussed in Section 4.2.3, the area of the nitrate plume is slightly larger than last quarter due
to a 'spur' in the plume extending from the vicinity of chloroform pumping well TW 4-19 to the
vicinity ofTW4-10, caused by the addition of new chloroform pumping well TW4-39, which has
a nitrate concentration of approximately 21 mg/L. MW-27, located west of TWN-2, and TWN-
18, located north ofTWN-3, bound the nitrate plume to the west and north (See Figure I-I under
Tab I). In addition, the southernmost (downgradient) boundary of the plume remains between
MW-30/MW-31 and MW-5/MW-11. Nitrate concentrations at MW-5 (adjacent to MW-11) and
MW-11 have historically been low (< 1 mg/L) or non-detect for nitrate (See Table 5). Non-
detectable nitrate at MW -11 is consistent with the relative stability of the downgradient margin
of the plume. MW-25, MW-26, MW-32, TW4-3, TW4-5, TW4-9, TW4-11, TW4-16, TW4-18,
TW4-25, TWN-1, and TWN-4 bound the nitrate plume to the east.
Although short-term fluctuations have occurred, nitrate concentrations in MW-30 and MW-31
have been relatively stable, demonstrating that plume migration is minimal or absent. Nitrate in
MW-30 decreased from 18 mg/L to 17.2 mg/L and nitrate in MW-31 decreased from 19.7 mg/L
to 18.8 mg/L. Based on the concentration data at MW-5, MW-11, MW-30, and MW-31, the
nitrate plume is under control.
Chloride has been relatively stable at MW -30 but is generally increasing at MW -31. The
apparent increase in chloride and relatively stable nitrate at MW -31 suggests a natural
attenuation process that is affecting nitrate but not chloride. A likely process that would degrade
nitrate but leave chloride unaffected is reduction of nitrate by pyrite. The likelihood of this
process in the perched zone is discussed in HGC, December 7 2012; Investigation of Pyrite in
the Perched Zone, White Mesa Uranium Mill Site, Blanding, Utah. Increases in chloride at MW-
27
30 are also expected to eventually occur as the nitrate/chloride plume continues to move
downgradient.
Nitrate mass removal by pumping and natural attenuation (expected to result primarily from
pyrite oxidation/nitrate reduction) act to lower nitrate mass within the plume. Changes resulting
from redistribution of nitrate within the plume are expected to result in both increases and
decreases in concentrations at wells within the plume and therefore increases and decreases in
mass estimates based on those concentrations, thus generating 'noise' in the mass estimates.
Furthermore, because the sum of sampling and analytical error is typically about 20%, changes
in the mass estimates from quarter to quarter of up to 20% could result from typical sampling
and analytical error alone. Longer-term analyses of the mass estimates that minimize the impact
of these quarter to quarter variations are expected to provide useful information on plume mass
trends. Over the long term, nitrate mass estimates are expected to trend downward as a result of
direct removal by pumping and through natural attenuation.
As specified in the CAP, once eight quarters of data were collected (starting with the first quarter
of 2013), a regression trend line was to be applied to the quarterly mass estimates and evaluated.
The trend line was to be updated quarterly and reevaluated as additional quarters of data were
collected. As the fourth quarter of 2014 constituted the eighth qumter as specified in the CAP,
the mass estimates were plotted, and a regression line was fitted to the data and evaluated. The
regression line was updated this quarter as shown in Figure M.1 of Tab M. The fitted line shows
a decreasing trend in the mass estimates.
During the current quarter, a total of approximately 106 lb of nitrate was removed by the
chloroform pumping wells and by nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-
2. Of the 106 lb removed during the current quarter, approximately 52 lb (or 49 %) .was removed
by the nitrate pumping wells.
The baseline nitrate (nitrate+nitrite as N) plume mass calculated as specified in the CAP (based
on second quarter, 2010 data) was approximately 43,700 lb. The mass estimate during the
current quarter (31 ,800 lb) was smaller than the mass estimate during the previous quarter
(32,230 lb) by 430 lb or approximately 1.3 %. This difference is attributable to slightly lower
average nitrate concentrations within the plume which offset the slightly increased plume area
resulting from the 'spur' extending southeast from TW4-19 to TW4-10 this quarter.
Nitrate concentrations outside the nitrate plume are greater than 10 mg/L at a few locations:
TW4-10 (14.8 mg/L), TW4-12 (25.8 mg/L), TW4-26 (15 mg/L), TW4-27 (19.3 mg/L), TW4-28
(25.5 mg/L), and new well TW4-38 (11.2 mg/L). Concentrations at TW4-18 are also
occasionally above 10 mg/L. Each of these wells is located southeast of the nitrate plume as
defined in the CAP and is separated from the plume by a well or wells having nitrate
concentrations that are either non-detect, or, if detected, are less than 10 mg/L. Concentrations at
TW4-10, TW4-26, TW4-27 and TW4-28 are within 20% of last quarter's concentrations while
the concentration at TW4-12 decreased by more than 20%.
Since 2010, nitrate concentrations at TW4-10 and TW4-18 have been above and below 10 mg/L
Concentrations were below 10 mg/L between the first quarter of 2011 and second quarter of
2013, and mostly close to or above 10 mg/L between the second quarter of 2013 and third
28
quarter of 2015. However, concentrations at TW 4-18 have been below 10 mg/L over the last four
quarters. Since 2010, concentrations at nearby well TW4-5 have exceeded 10 mg/L only twice,
and concentrations at nearby wells TW4-3 and TW4-9 have remained below 10 mg/L. Nitrate at
TW4-5, TW4-10, and TW4-18 is associated with the chloroform plume, and is within the capture
zone of the chloroform pumping system. Elevated nitrate at TW4-12, TW4-26, TW4-27, TW4-
28, and new well TW4-38 is likely related to former cattle ranching operations at the site.
Increases in both nitrate and chloride concentrations at wells near the northern wildlife ponds
(for example TW4-18) were anticipated as a result of reduced dilution caused by cessation of
water delivery to the northern wildlife ponds. However, decreasing nitrate concentrations at
TW4-10 and TW4-18 from the first through third quarters of 2014 after previously increasing
trends (interrupted in the first quarter of 2014) suggested that conditions in this area had
stabilized. The temporary increase in nitrate concentration at TW 4-18 in the third quarter of 2015
and the generally increased nitrate at TW4-5 and TW4-10 since the second quarter of 2015
suggest that reduced wildlife pond recharge is still impacting concentrations in downgradient
wells.
EFRI and its consultants have raised the issues and potential effects associated with cessation of
water delivery to the northern wildlife ponds in March, 2012 during discussions with DWMRC
in March 2012 and May 2013. While past recharge from the ponds has helped limit many
constituent concentrations within the chloroform and nitrate plumes by dilution, the associated
groundwater mounding has increased hydraulic gradients and contributed to plume migration.
Since use of the northern wildlife ponds ceased in March 2012, the reduction in recharge and
decay of the associated groundwater mound was expected to increase many constituent
concentrations within the plumes while reducing hydraulic gradients and rates of plume
migration.
The net impact of reduced wildlife pond recharge is expected to be beneficial even though it was
also expected to result in temporarily higher concentrations until continued mass reduction via
pumping and natural attenuation ultimately reduce concentrations. Temporary increases in nitrate
concentrations are judged less important than reduced nitrate migration rates. The actual impacts
of reduced recharge on concentrations and migration rates will be defined by continued
monitoring.
Nitrate mass removal from the perched zone was increased substantially by the start-up of nitrate
pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 during the first quarter of 2013.
Continued operation of these wells is therefore recommended. Pumping these wells, regardless
of any short term fluctuations in concentrations detected at the wells, helps to reduce
downgradient nitrate migration by removing nitrate mass and reducing average hydraulic
gradients, thereby allowing natural attenuation to be more effective. Continued operation of the
nitrate pumping system is expected to eventually reduce nitrate concentrations within the plume
and to further reduce or halt downgradient nitrate migration.

RE: 4th Quarter Nitrate 2016
Dear Garrin Palmer: LabSetiD: 1610271
American West Analytical Laboratories received sample(s) on 10/14/2016 for the
analyses presented in the following report.
American West Analytical Laboratories (AW AL) is accredited by The National
Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is
state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,

RE: 4th Quarter Chloroform 2016
Dear Garrin Palmer: Lab Set ID: 1610270
American West Analytical Laboratories received sample(s) on 10/14/2016 for the
analyses presented in the following report.
American West Analytical Laboratories (AW AL) is accredited by The National
Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is
state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,

RE: 4th Quarter Chloroform 2016
Dear Garrin Palmer: Lab Set ID : 1611262
American West Analytical Laboratories received sample(s) on 11/11/2016 for the
analyses presented in the following report.
American West Analytical Laboratories (AWAL) is accredited by The National
Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is
state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,
