1.0 INTRODUCTION
The Utah Department of Environmental Quality ("UDEQ") Division of Radiation Control
("DRC") 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,
DRC 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 UDEQ
Docket No. UGW12-04 for the fourth quarter of 2014. 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 2014.
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.
1
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 3
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 repmted in the chloroform quarterly monitoring report only.
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 DRC-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 3. 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
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 6, 2012 was confirmed
for all analytes, as discussed later in this report.
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, TW4-19, TW4-20, and TW4-4, 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, TW4-21, 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.
3
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.
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-
dectect) 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, in
addition to the pre-event decontamination described above.
4
2.2.2 Piezometer Sampling
Samples are collected from Piezometers 1, 2 and 3, 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 ("AW AL").
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 DRC in 2011. Pursuant to theCA, the CAP was submitted to the Director of the
Division of Radiation Control (the "Director") on May 7, 2012. The CAP describes activities
5
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
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
QAJQC requirements established in the QAP and Chloroform QAP were met.
6
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
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 conformed with the QAP purging and
field measurement requirements. A summary of the purging techniques employed and field
measurements taken is described below:
Purcing Two Casin~Z: 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.
Pmging a W 11 to Dryness aod Stability of a Lim.jtcd Li t of Field Parameter.
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.
Continuously Pumped Wells
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
7
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 review of the field sheets for compliance with QAP requirements resulted in the
observations noted below. The QAP requirements in Attachment 2-3 specifically state that field
parameters must be stabilized to within 10% over at least 2 consecutive measurements for wells
purged to two casing volumes or to dryness. The QAP Attachment 2-3 states that turbidity
should be less than 5 NTU prior to sampling unless the well is characterized by water that has a
higher turbidity. The QAP Attachment 2-3 does not require that turbidity measurements be less
than 5 NTU prior to sampling. As such the noted observations regarding turbidity measurements
greater than 5 NTU below are included for information purposes only.
• Six well measurements exceeded the QAP's 5 NTU turbidity goal as noted in Tab H. All
required turbidity RPD's met the QAP Requirement to stabilize within 10%.
EFRI's letter to DRC of March 26, 2010 discusses further why turbidity does not appear to be an
appropriate parameter for assessing well stabilization. In response to DRC's subsequent
correspondence dated June 1, 2010 and June 24, 2010, EFRI completed a monitoring well
redevelopment program. The redevelopment report was submitted to DRC on September 30,
2011. DRC responded to the redevelopment report via letter on November 15, 2012. Per the
DRC letter dated November 15, 2012, the field data generated this quarter are compliant with the
turbidity requirements of the approved QAP.
3.4.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample holding
time checks are provided in Tab 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 reporting limits due to matrix interference or required dilution
due to the sample concentration. However, in all of those cases the analytical results were
8
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%.
The duplicate results were within a 20% RPD. Results of the RPD test are provided in Tab H.
3.4.6 Other Laboratory QA/QC
Section 9.2 of the QAP requires that the laboratory's QA/QC Manager check the following items
in developing data reports: (1) sample preparation information is correct and complete, (2)
analysis information is correct and complete, (3) appropriate Analytical Laboratory procedures
are followed, (4) analytical results are correct and complete, (5) QC samples are within
established control limits, (6) blanks are within QC limits, (7) special sample preparation and
analytical requirements have been met, and (8) documentation is complete. In addition to other
laboratory checks described above, EFRI' s QA Manager rechecks QC samples and blanks (items
(5) and (6)) to confirm that the percent recovery for spikes and the relative percent difference for
spike duplicates are within the method-specific required limits, or that the case narrative
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
9
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 map indicates that perched water flow ranges from generally
southwesterly beneath the Mill site and tailings cells to generally southerly along the eastern and
western margins of White Mesa. Perched water mounding associated with the wildlife ponds
locally changes the generally southerly perched water flow patterns. For example, northeast of
the Mill site, mounding associated with wildlife ponds results in locally northerly flow near
PIEZ-1. The impact of the mounding associated with the northern ponds, to which water has not
been delivered since March 2012, is diminishing and is expected to continue to diminish as the
mound decays due to reduced recharge.
10
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, has resulted in changing
conditions that are expected to impact constituent concentrations and migration rates within the
plumes. Specifically, past recharge from the ponds has helped limit many constituent
concentrations within the plumes by dilution while the associated groundwater mounding has
increased hydraulic gradients and contributed to plume migration. Since use of the northern
wildlife ponds ceased in March 2012, the reduction in recharge and decay of the associated
groundwater mound are expected to increase many constituent concentrations within the plumes
while reducing hydraulic gradients and acting to reduce rates of plume migration. EFRI and its
consultants have raised the issues and potential effects associated with cessation of water
delivery to the northern wildlife ponds during discussions with DRC in March 2012 and May
2013.
The impacts associated with cessation of water delivery to the northern ponds are expected to
propagate downgradient (south and southwest) over time. Wells close to the ponds are generally
expected to be impacted sooner than wells farther downgradient of the ponds. Therefore,
constituent concentrations are generally expected to increase in downgradient wells close to the
ponds before increases are detected in wells farther downgradient of the ponds. Although such
increases are anticipated to result from reduced dilution, the magnitude and timing of the
increases are 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. The potential exists for
some wells completed in higher permeability materials to be impacted sooner than some wells
completed in lower permeability materials even though the wells completed in lower
permeability materials may be closer to the 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 mixing 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 may be especially 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. The
overall impact is expected to be generally higher constituent concentrations in these wells over
the short term until mass reduction resulting from pumping and natural attenuation eventually
reduce concentrations.
In addition to changes in the flow regime caused by reduced wildlife pond recharge, perched
flow directions are locally influenced by operation of the chloroform and nitrate pumping wells.
11
As shown in the detail water level map provided under Tab C, well defined cones of depression
are evident in the vicinity of all chloroform pumping wells except TW4-4, which began pumping
in the first quarter of 2010. Although operation of chloroform pumping well TW4-4 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 TW4-14.
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 upgradient of the nitrate
pumping wells.
Capture associated with nitrate pumping is expected 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
will, however, require more data to be collected as part of 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 TW 4-4. Changes in water levels at
wells immediately south of TW4-4 resulting from TW4-4 pumping are expected to be muted
because TW4-4 is located at a transition from relatively high to relatively low permeability
conditions south (downgradient) of TW4-4. The permeability of the perched zone at TW4-6 and
TW4-26, recently installed wells TW4-29, TW4-30, TW4-31, TW4-33, and TW4-34, and new
well TW4-35 is one to two orders of magnitude lower than at TW4-4. Any drawdown of water
levels at wells immediately south of TW4-4 resulting from TW4-4 pumping is also difficult to
determine because of the general, long-term increase in water levels in this area due to recharge
from the wildlife ponds.
Water levels at TW4-4 and TW4-6 increased by nearly 2.7 and 2.9 feet, respectively, between
the fourth quarter of 2007 and the fourth quarter of 2009 Gust prior to the start of TW 4-4
pumping) 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 TW4-6 is within the hydraulic
influence ofTW4-4. Furthermore, water levels at TW4-6 have been trending downward since the
fourth quarter of 2013 suggesting an additional influence related to the cessation of water
delivery to the nmthern wildlife ponds as discussed above. (note: hydrographs for these wells are
provided in the quarterly Chloroform Monitoring Report). Recharge from the southern wildlife
pond is expected to continue to have an effect on water levels near TW 4-4 even as the
groundwater mound associated with recharge from the northern ponds diminishes over time due
to cessation of water delivery to those ponds.
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 ofTW4-4 and TW4-6. For
the current quarter, the water level at TW4-14 was measured at approximately 5530.4 feet above
12
mean sea level ("ft amsl"). This is approximately 8 feet lower than the water level at TW 4-6
(approximately 5538.7 ft amsl) and 13 feet lower than the water level at TW4-4 (approximately
5543.7 ft amsl) even though TW4-4 is pumping.
Well TW4-27 (installed south of TW4-14 in the fourth quarter of 2011) has a static water level
of approximately 5527.8 ft amsl, similar to TW4-14 (approximately 5530.4 ft amsl). TW4-27
was positioned at a location considered likely to detect any chloroform present and/or to bound
the chloroform plume to the southeast and east (respectively) of TW4-4 and TW4-6. As will be
discussed below, groundwater data collected since installation indicates that TW 4-27 does
indeed bound the chloroform plume to the southeast and east of TW 4-4 and TW 4-6
(respectively); however chloroform exceeding 70 f.!g/L has been detected at recently installed
temporary perched wells TW4-29 (located south of TW4-27) and TW4-33 (located between
TW4-4 and TW4-29).
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 ofTW4-4 and TW4-6. For
the current quarter, the water level at TW4-14 was measured at approximately 5530.4 feet above
mean sea level ("ft amsl"). This is approximately 8 feet lower than the water level at TW4-6
(approximately 5538.7 ft amsl) and 13 feet lower than the water level at TW4-4 (approximately
5543.7 ft amsl) even though TW4-4 is pumping.
Well TW4-27 (installed south of TW4-14 in the fourth quarter of 2011) has a static water level
of approximately 5527.8 ft amsl, similar to TW4-14 (approximately 5530.4 ft amsl). Prior to the
installation of TW4-27, the persistently low water level at TW4-14 was considered anomalous
because it appeared to be downgradient of all three wells TW4-4, TW4-6, and TW4-26, yet
chloroform had not been detected at TW4-14. Chloroform had apparently migrated from TW4-4
to TW4-6 and from TW4-6 to TW4-26 which 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 (5537.1 feet amsl) is,
however, lower than water levels at adjacent wells TW4-6 (5538.7 feet amsl), and TW4-23
(5540.3 feet amsl), as shown in the detail water level map under Tab C.
Hydraulic tests indicate that the permeability at TW4-27 is an order of magnitude lower than at
TW4-6 and three orders of magnitude lower than at TW4-4 (see Hydro Geo 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). The similar water levels at TW4-14 and TW4-27, and the low permeability
estimate at TW4-27 suggest that both wells are completed in materials having lower 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
recently installed wells TW4-29, TW4-30, TW4-31, TW4-33 and TW4-34 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
13
[As-Built Report]). Hydraulic tests also indicate that the permeability at TW4-36 is slightly
higher than but comparable to the low permeability at TW4-27, suggesting that TW4-36, TW4-
14 and TW4-27 are completed in a continuous low permeability zone.
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.
A comparison of the water table contour maps for the current quarter (fourth quarter of 2014) to
the water table contour maps for the previous quarter (third quarter of 2014) indicates slightly
larger drawdowns related to operation of chloroform pumping wells MW-26and TW4-20 and
nitrate pumping well TW4-25. Nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2
were brought into operation during the first quruter of 2013 and their impact on water level
patterns was evident as of the fourth quarter of 2013. While water levels in nitrate pumping wells
TW4-22, TW4-24, and TW4-25 showed decreases, the water level at TWN-2 showed an increase
this quarter.
As discussed in Section 4.1.1, pumping at chloroform well TW 4-4, which began in the first
quarter of 2010, has depressed the water table near TW4-4, but a well-defined cone of depression
is not clearly evident, likely due to variable permeability conditions near TW4-4 and the
persistently low water level at adjacent well TW4-14.
Small ( <1 foot) changes in water levels were reported at the majority of site wells; water levels
and water level contours for the site have not changed significantly since the last quarter except
for a few locations. Reported decreases in water levels (increases in drawdown) of approximately
3.4, 1.6, 1.4, 2.5, and 2.8 feet occurred in chloroform pumping wells MW-26 and TW4-20, and
nitrate pumping wells TW4-22, TW4-24, and TW4-25, respectively. An increase in water level
(decrease in drawdown) of approximately 5 feet was reported for nitrate pumping well TWN-2.
Changes in water levels at other pumping wells (chloroform pumping wells MW -4, TW 4-4, and
TW 4-19 were less than 1 foot. 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.
Although decreases in water levels (decreases in drawdown) occuued at chloroform pumping
wells MW-26 and TW4-20, and nitrate pumping wells TW4-22, TW4-24, and TW4-25 the
apparent capture of these wells relative to other pumping wells has increased in some cases and
decreased in others, while the overall capture of the combined pumping systems has increased
slightly.
Reported water level decreases of less than 1 foot at Piezometers 1 through 3, TWN-1, TWN-4,
TWN-6, TWN-18, and MW-19 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 0.6 feet and
0.7 feet at Piezometers 4 and 5 may result from reduced recharge at the southern wildlife pond.
14
Reported water levels decreased by approximately 4.3 feet at MW-20 and increased by
approximately 4.8 feet at MW-37 between the previous quarter and the current quarter. Water
level variability at these wells is likely the result of low permeability and variable intervals
between purging/sampling and water level measurement. A decrease in water level of
approximately 2.9 feet and increases of approximately 2.4 feet and 2.9 feet were reported at DR-
17, MW-23 and TW4-21, respectively.
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 up gradient of TW 4-22 and TW 4-24 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 DRC and International Uranium (USA) Corp. The procedure for
calculating nitrate capture zones is as follows:
15
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.
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, reported changes in water levels at nitrate pumping wells other than
TWN-2 were less than three feet, as were the reported water level changes at chloroform
pumping wells other than MW-26. A large increase of approximately 5 feet was reported for
nitrate pumping well TWN-2, and a decrease of approximately 3.4 feet was reported for
chloroform pumping well MW-26. Overall, the apparent capture of the combined nitrate and
chloroform pumping systems has increased slightly since last quarter.
The capture associated with nitrate pumping wells 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 is assumed
to represent a steady state 'background' condition that includes constant recharge, hydraulic
gradients, and saturated thicknesses, and does not account for reduced recharge and saturated
thickness caused by cessation of water delivery to the northern wildlife ponds since March, 2012.
Changes after pumping are conservatively assumed to result only from pumping. As will be
discussed below, the average combined nitrate pumping rate for the quarter is approximately the
same as, to a factor approximately 2.1 times greater than, the calculated pre-pumping rate of
perched water flow through the nitrate plume.
The cumulative volume of water removed by TW4-22, TW4-24, TW4-25, and TWN-2 during
the current quarter was approximately 357,427 gallons. This equates to an average total
extraction rate of approximately 2.7 gpm over the 92 day quarter. This average accounts for time
periods when pumps were off due to insufficient water columns in the wells.
Pre-pumping flow through the nitrate plume near TW4-22 and TW4-24 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
16
(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 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 also 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.
The hydraulic gradient and saturated thickness used in the calculations are assumed to represent
a steady state 'background' condition. However, assumption of a steady state 'background' is
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
are declining as a result of two factors: reduced recharge from the ponds, and the effects of
nitrate pumping. Separating the impacts of nitrate pumping from the impacts of reduced recharge
from the ponds is problematic. Should pumping cease and 'background' conditions be allowed to
re-establish, however, smaller hydraulic gradients and saturated thicknesses would be expected
due to reduced recharge, which would lower estimates of 'background' flow.
As a result, the 'background' flow calculated using the hydraulic gradient of 0.025 ft/ft and
saturated thickness of 56 feet is considered conservatively large. Furthermore, using the
arithmetic average hydraulic conductivity of a subset of plume wells having the highest
conductivities is considered less representative of actual conditions than using the geometric
average conductivity of all of the plume wells. Nitrate pumping may therefore exceed flow
through the plume by a factor greater than 2.1, the high end of the calculated range.
The CAP states that MW-5, MW-11, MW-30, and MW-31 are located downgradient ofTW4-22
and TW4-24. MW-30 and MW-31 are within the plume near its downgradient edge and MW-5
17
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 concentrations of nitrate in MW-30 and
MW -31 remain stable or decline, and concentrations of nitrate 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 plume has not migrated downgradient to MW -5 or MW -11 because the nitrate concentration
at MW-5 is approximately 0.2 mg/L this quarter and nitrate was not detected at MW-11.
Between the previous and current quarters, nitrate concentrations increased in both MW-30 and
MW-31. Nitrate in MW-30 increased from 13.8 mg/L to 16.2 mg/L and nitrate in MW-31
increased from 15.2 mg/L to 20.9 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 increasing at MW-31 (see Tab J and Tab K,
discussed in Section 4.2.4). The apparent increase in chloride and 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
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
Increases in nitrate concentrations in most wells within the nitrate plume since last quarter have
resulted in a slight expansion of the plume area. The concentration in TWN-3 decreased from
approximately 20 mg/L to 19 mg/L; the concentration in MW-30 increased from approximately
14 mg/L to 16 mg/L; and the concentration in MW-31 increased from approximately 15 mg/L to
21 mg/L. The concentration in nitrate pumping well TWN-2 increased from approximately 42
mg/L to 71 mg/L; the concentration in nitrate pumping well TW4-22 increased from
approximately 42 mg/L to 55 mg/L; and the concentration in nitrate pumping well TW4-24
increased from approximately 32 mg/L to 36 mg/L. In addition, the concentration in TW4-21
increased from 7.1 mg/L last quarter to 10 mg/L this quarter, bringing it again just within the
nitrate plume boundary. (see Tab J and Tab K, discussed in Section 4.2.4).
The nitrate concentration at TW4-18 (located east of the nitrate plume) increased from 9.8 mg/L
to 11.1 mg/L after decreasing for the previous three quarters. Changes in nitrate concentrations
near TW 4-18 are expected to result from changes in pumping and from the cessation of water
18
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 wells
downgradient of the ponds. However, decreasing nitrate concentrations at most wells in the
vicinity of TW4-18 over the previous three quarters after previous increases suggests that
conditions in this area have stabilized.
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 (primarily
chloroform pumping well MW-26). 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) continue to
be relatively stable, demonstrating that plume migration is minimal or absent. With regard to
chloroform, since the initiation of nitrate pumping, the boundary of the chloroform plume has
migrated to the west toward nitrate pumping well TW4-24, and more recently has migrated to the
southwest to reincorporate chloroform monitoring wells TW4-6 and TW4-16. 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% in the following wells
compared to last quarter: MW-26, MW-27, MW-31, TW4-10, TW4-16, TW4-19, TW4-
20, TW4-21, TW4-22, and TWN-2;
b) Nitrate concentrations have decreased by more than 20% in the following wells
compared to last quarter: TW4-25 and TWN-4;
c) Nitrate concentrations have remained within 20% in the following wells compared to
last quarter: MW-30, TW4-5, TW4-18, TW4-24, TWN-1, TWN-3, TWN-7 and TWN-
18;and
d) MW-11, MW-25, and MW-32 remained non-detect
19
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 wells MW-26, TW4-19, and TW4-20;
nitrate pumping wells TW4-22, TW4-25 and TWN-2; and non-pumping wells MW-27, MW-31,
TW4-10, TW4-16, TW4-21, and TWN-4. TW4-10 and TW4-16 are located adjacent to
chloroform pumping well MW-26; TW4-21 is located adjacent to chloroform pumping well
TW4-19; and TWN-4 is located between the northern wildlife ponds and nitrate pumping wells
TW4-25 and TWN-2. 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.
Concentrations at TW4-21 are also influenced by its location near the eastern nitrate and
northern chloroform plume boundaries. MW -31 is located in the downgradient portion of the
nitrate plume and is expected to be influenced by changes in upgradient pumping at nitrate
pumping wells TW4-22 and TW4-24 and chloroform pumping wells MW-26, TW4-19 and
TW4-20.
As discussed in Section 4.2.3, the nitrate concentration at TW4-21 increased from 7.1 mg/L last
quarter to 10 mg/L this quarter, bringing it again just within the nitrate plume boundary. The
nitrate concentration in nitrate pumping well TW4-25 decreased from approximately 1.6 mg/L
last quarter to 1.0 mg/L this quarter. The nitrate concentrations in chloroform pumping wells
MW-26, TW4-19, and TW4-20 increased from approximately 0.7 mg/L, 1.6 mg/L and 4.3 mg/L,
respectively, to approximately 1.1 mg/L, 4.7 mg/L, and 7.7 mg/L. The chloroform concentration
at nitrate pumping well TW4-24 decreased from 76.3 ~-tg/L to 25.8 ~-tg/L. The decrease at TW4-
24 pushed the chloroform plume boundary back to the east of TW4-24; last quarter, a chloroform
concentration increase from 62.7 ~-tg/L to 76.3 ~-tg!L moved the chloroform plume boundary to
the west of TW4-24. Chloroform changes at TW4-22 and TW4-24 are likely in response to the
start-up of nitrate pumping in the first qumter of 2013 and are affected by the presence of
historically high chloroform concentrations at adjacent, cross-gradient well TW4-20. 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). MW-25, MW-26, MW-32, TW4-16, TW4-19, TW4-20,
TW4-25, TWN-1, and TWN-4 bound the nitrate plume to the east.
As discussed above, the areal extent of the plume has expanded slightly, with the plume
boundaries moving outward in some areas, primarily due to increases in concentrations at wells
within the plume. Nitrate concentrations outside the nitrate plume exceed 10 mg/L at a few
locations: TW4-12 (16.1 mg/L), TW4-26 (12.3 mg/L), TW4-27 (28.2 mg/L), and TW4-28 (16.5
mg/L). All these wells are located southeast of the nitrate plume as defined in the CAP and all
are separated from the plume by wells having nitrate concentrations that are either non-detect, or,
if detected, are less than 10 mg/L. Concentrations at TW4-26, TW4-27 and TW4-28 are within
20% of their concentrations during the previous quarter, while the concentration at TW 4-12
increased more than 20%, from approximately 13 mg/L to 16 mg/L. From the third quarter of
2013 through the second quarter of 2014, nitrate concentrations at TW4-10 and TW4-18
exceeded 10 mg/L. Although last quarter, nitrate concentrations at both TW4-10 and TW4-18
20
decreased to 9.8 mg/L, both are again above 10 mg/L this quarter. Elevated nitrate
concentrations at these wells are associated with the chloroform plume, and both are within the
capture zone of the chloroform pumping system. Elevated nitrate at TW4-12, TW4-26, TW4-27,
and TW4-28 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. Although changes
were within 20%, more increases were detected than decreases. Increases in concentrations at
wells near (and downgradient of) the northern wildlife ponds are anticipated as a result of
reduced dilution caused by cessation of water delivery to the northern wildlife ponds.
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 1,173 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 109 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 109 lb removed during the current quatter, approximately 93 lb, (or 85 %), was
removed by the nitrate pumping wells.
Baseline mass and current quarter mass estimates (nitrate + nitrite as N) for the nitrate plume are
approximately 43,700 lb and 34,370 lbs, respectively. Mass estimates were calculated within the
plume boundaries as defined by the kriged 10 mg!L isocon 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 mass 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 9,330 lb,
and this difference is greater than the amount of nitrate mass removed directly by pumping.
Changes in the quarterly mass estimates are expected to result primarily from 1) nitrate mass
21
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 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 (34,370 lb) was larger than the mass estimate
during the previous quarter (24,140 lb) by 10,230 lb or 42 %. This difference results from higher
nitrate concentrations measured in most wells within the plume and the resulting increased areal
extent this quarter compared to last 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 have been collected (starting with the first
quarter of 2013), a regression trend line is to be applied to the quarterly mass estimates and
evaluated. The trend line will then be updated quarterly and reevaluated as additional quarters of
data are collected. The evaluation will determine whether the mass estimates are increasing,
decreasing, or stable.
As the current quarter constitutes the eighth quarter as specified in the CAP, the mass estimates
were plotted and a regression line fitted to the data, as shown in Figure M.1 of Tab M. The fitted
line shows a decreasing trend in the mass estimates.
As discussed above, the quarterly mass estimates are based on gridded (kriged) concentration
data and saturated thicknesses (derived from gridded water level and base of perched zone data).
Mass estimates are thus expected to depend primarily on wells within the plume having both
relatively high concentrations and saturated thicknesses. An analysis of the relative influence of
individual wells on the mass estimates was performed based on data from the eight wells
originally within the plume (TWN-2, TWN-3, TW4-21, TW4-22, TW4-24, TW4-25, MW-30,
and MW-31). Although TW4-21 has been both within and outside the plume, and TW4-25 is no
longer within the plume, these wells were originally within the plume as defined in the CAP and
were included in the analysis. Both are important due to their close proximities to the plume
boundary.
22
Figures M.2 through M.9 are plots comparing the mass estimates to concentration, saturated
thickness, and the product of concentration and saturated thickness (in units of pounds per square
foot of plume [lbs/ft2]) at each well originally within the plume. Examination of these plots
suggests that changes in concentration and in the product of concentration and saturated
thickness at TWN-2 have the largest impact on changes in the mass estimates. This is reasonable
because both concentrations and saturated thicknesses at TWN-2 are relatively large.
Ten methods were used to quantitatively evaluate the relative influence of individual wells on the
mass calculations. Well rankings derived from the ten methods are provided in Table M.l, with a
rank of 1 indicating the greatest influence and a rank of 8 indicating the least influence.
Methods 1, 2, and 3 rank each well based on the averages of concentration, saturated thickness,
and product of concentration and saturated thickness, respectively. Averages were calculated
from data over the last eight quarters (including the current quarter) and the baseline (second
quarter, 2010) data.
Methods 4, 5, 6, and 7 constitute sensitivity analyses using average concentration and saturated
thickness data from the baseline (second quarter, 2010) data, and data from the last eight quarters
(including the current quarter). These averages were used to compute an 'average plume' and
'average plume' mass estimate. Thirty two additional mass estimates were then computed by
leaving out of the gridding process either the data from one of the original eight wells within the
plume (method 4) or by modifying the data from one of the original eight wells within the plume.
Data modification included: increasing the average nitrate concentration at a particular well by
20% (method 5); decreasing the average nitrate concentration at a particular well by 20%
(method 6); and decreasing the average saturated thickness at a particular well by 20% (method
7). These methodologies automatically account for the variation in the lateral influence of
individual wells, and the kriged plume boundaries are allowed to change based on the imposed
changes.
Methods 8, 9, and 10 constituted evaluation of the relative influence of each of the eight original
wells on the kriged 'average plume'. A polygonal estimator was used to apportion the mass,
volume, and average concentration associated with each well within the kriged average plume
boundary. These methodologies also account for variations in the lateral influence of individual
wells within the fixed 'average plume' boundary.
Results of methods 1 through 3, 4 through 7, 8 through 10, and 3 and 8, were also scored
collectively for overall rank. In each case, the score for a well consists of the sum of ranks for
that well obtained by the indicated methods. Grouping of the methods were based on similarity.
As discussed above, methods 1 through 3 rank influence based on raw concentration and
saturated thickness data at individual wells and do not account for variable lateral influence of
individual wells. Methods 4 through 10 rank influence based on gridded data and therefore
account for variation in the lateral influence of wells. Methods 4 through 7 constitute sensitivity
analyses; and methods 8 through 10 apportion mass, volume, and average concentration within
the average kriged plume to individual wells using a polygonal estimator. Methods 3 and 8 are
similar in that both rank influence based on the product of concentration and saturated thickness.
Because method 8 ranks influence based on gridded data it additionally accounts for lateral
influence.
23
The results of collectively scoring methods 1 through 3 are shown in Table M.2. The wells in
order of importance are: TWN-2, TW4-22, MW-31, TW4-24, TWN-3, TW4-21ffW4-25, and
MW-30.
The results of collectively scoring methods 4 through 7 are shown in Table M.3. Wells in
descending order of influence are: TWN-2, TW4-24/MW-31, TW4-22, MW-30, TW4-25, TWN-
3, and TW4-21. As indicated in Table M.1, rankings for methods 5, 6, and 7 were similar, with
the top four consisting, in descending influence, of TW4-24, TWN-2, MW-31, and TW4-22.
Method 4 ranked the top 4 wells as TWN-2, MW-30, MW-31, and TW4-22.
The results of collectively scoring methods 8 through 10 are shown in Table M.4. Wells in
descending order of influence are: TWN-2, TW4-22, MW-31, TW4-24, TWN-3, TW4-21/TW4-
25, and MW-30. As indicated in Table M.1, rankings for methods 8, 9, and 10 were similar with
regard to the top 4 rankings; wells TWN-2, TW4-22, TW4-24, and MW-31 were in the top 4 of
each method albeit in different order for each method. The top four (in descending influence)
were for method 8: TW4-24, TWN-2, TW4-22, and MW-31; for method 9: TW4-24, TWN-2,
MW-31, and TW4-22; and for method 10: TWN-2, TW4-22, TW4-24, and MW-31.
The results of collectively scoring methods 3 and 8 are shown in Table M.5. The ranking of the
top four consists (in descending order of influence) of TWN-2, TW4-24, TW4-22, and MW-31.
The result of collectively scoring all methods is shown in Table M.6. Although this scoring
lumps dissimilar methods, the results are similar to those obtained from the collective scoring of
groups of similar methods described above. Well TWN-2 is ranked as having the most influence.
The top four wells (in descending order of influence) are: TWN-2, TW4-24, MW-31, and TW4-
22.
The results of the visual and quantitative analyses indicate that var1atwns in plume mass
estimates can be expected to depend primarily on variations in data from TWN-2. Wells TW4-
22, TW4-24, and MW-31 (not necessarily in that order) are collectively the next most important
with regard to influence on 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. The purpose of the test is to serve as an interim action that will
24
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 and TW4-20 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, and at
selected temporary wells and permanent monitoring wells on a monthly basis.
• Measurement of pumping history, including:
pumping rates
total pumped volume
operational and non-operational periods.
• Periodic sampling of pumped water for chloroform and nitrate/nitrite analysis and
other constituents
• Measurement of water levels weekly at TW4-22, TW4-24, TW4-25, and TWN-02
commencing January 28, 2013, and on a monthly basis selected temporary wells
and permanent monitoring wells.
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. 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 and TWN-02 are included under Tab C.
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, TW4-21, 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.
25
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.
Specific operational problems observed with the well or pumping equipment which occurred
during the quarter are noted for each well below in Sections 5.4.1 through 5.4.4.
The following two issues were noted as affecting multiple wells in the pumping network as and
are not repeated under the Section for each well.
On November 23, 2014, the Mill experienced a power outage resulting from high winds (in
excess of 60+ mph) in the area. During the power outage all of the pumping wells (MW -04,
TW4-04, MW-26, TW4-19, TW4-20, TW4-22, TW4-24, and TW4-25) ceased pumping. Power
was partially restored to portions of the Mill on November 23, 2014 and power was fully
restored to the entire Mill facility by 7:00AM November 24, 2014. Pumping of the chloroform
wells was restored within 24-hours of discovery. No official notifications to DRC were required
as the issue was rectified within 24-hours. DRC was notified by telephone that the issue was
resolved within the 24-hour window and no further actions were necessary.
On December 29, 2014, an unscheduled down time occurred which lasted more than 24 hours.
The down time was the caused by frozen transfer lines resulting from system/discharge line
upgrades. The upgrades were necessary to add three more continuous pumping wells to the
chloroform pumping network. The up-sizing of the discharge line required that the old l-inch
lines be excavated while the 4-inch lines were connected. During the excavation the l-inch
lines, which were still connected to the existing pumping system, were exposed to the elements
in the open trench. The Mill experienced below freezing temperatures for most of the week prior
to December 29, 2014. The down time during construction caused six continuous pumping wells
(MW-04, MW-26, TW4-04, TW4-20, TW4-22, and TW4-24) to be off (not pumping) until the
completion of construction. Initial notice of this outage was given by telephone to DRC at
approximately 1:00pm on Monday December 29, 2014 (within 24 hours of the discovery). As
required by the O&M Plan, a 5-day written notification was also provided to DRC. The 5-day
written notification is included in Tab N. The pumps were returned to service On January 9,
2015.
Unless specifically noted below, no additional operational problems were observed with the well
or pumping equipment during the quarter.
5.4.1 MW-04
On November 24, 2014, Mill Field Personnel noted that the discharge line from MW-04 was
frozen. The frozen discharge line was likely caused by the power outage which began the
previous day as noted above. Upon discovery, the discharge line was thawed and full
functionality was restored within several hours of discovery. No official notifications to DRC
were required as the issue was rectified within 24-hours.
26
On December 8, 2014 Mill Field Personnel noted that the heat lamp on MW-04 had burned out.
No adverse affects were noted due to the nonfunctioning bulb. The bulb was immediately
replaced. No official notifications to DRC were required as the issue was rectified within 24-
hours.
On December 22, 2014, Mill Field Personnel noted that due to intermittent power issues, the
pump timer had lost its settings. The pump timer was reset immediately upon discovery. No
official notifications to DRC were required as the issue was rectified within 24-hours.
5.4.2 TW 4-04
On November 24, 2014, Mill Field Personnel noted that the discharge line and the flow meter
from TW4-04 were frozen. Mill Field Personnel also noted that the flow meter on TW4-04 was
cracked. The frozen discharge line and flow meter was likely caused by the power outage which
began the previous day as noted above. Upon discovery, the discharge line was thawed and the
flow meter was replaced and full functionality was restored within several hours of discovery.
No official notifications to DRC were required as the issue was rectified within 24-hours.
5.4.3 MW-26
On November 18, 2014 power was shut down to several pumping wells to upgrade the power
pole transformer to accommodate more pumping wells being added to the pumping network.
The power was shut down for a few hours during the upgrade. When power was restored the
pumping wells were checked and it was noted that the MW-26 pump timer had lost its settings.
The pump timer was reset immediately upon discovery. No official notifications to DRC were
required as the issue was rectified within 24-hours.
5.4.4 TW4-25
On November 3, 2014 Mill Field Personnel noted that the TW4-25 pump had lost electrical
power due to a poor connection. The well was inspected during the monthly depth check on
October 29, 2014 and was fully operational at that time. The power loss happened between the
monthly depth check and the weekly inspection. Some loss of pumped volume may have
occurred as a result of the power loss. The power was immediately restored upon discovery.
The pump timer was reset immediately upon discovery. No official notifications to DRC were
required as the issue was rectified within 24-hours.
On November 26, 2014, Mill Personnel notified EFRI Corporate Environmental Staff that
pumping of TW4-25 had to be stopped to accommodate construction activities in the area
associated with the ammonium sulfate concrete cover required under the Nitrate CAP. Pumping
was stopped for several hours and no notification to DRC was necessary. On December 1, 2014,
Mill Field Personnel requested cessation of pumping in TW4-25 for several days to
accommodate re-routing of the discharge lines and electrical lines. The discharge and electrical
lines were rerouted as a result of the ammonium sulfate concrete cover. EFRI Corporate
Environmental Staff contacted DRC and requested approval for the cessation of pumping. DRC
provided verbal approval and requested the incident be documented in this report. Pumping was
resumed on December 4, 2014.
27
On December 8, 2014 during the weekly check, Mill Field Personnel noted that the TW4-25
pump timer had lost its settings. The pump timer was reset immediately upon discovery. No
official notifications to DRC were required as the issue was rectified within 24-hours.
6.0 CORRECTIVE ACTION REPORT
There are no coiTective actions required during the current monitoring period.
6.1 Assessment of Previous Quarter's Corrective Actions
The third quarter nitrate report included a corrective action report to address low level nitrate
contamination in the rinsate samples. Since the DIFB collected for the third quarter were non-
detect, EFRI believed the nitrate present in the rinsate samples was due to laboratory
contamination and did not represent actual nitrate contamination. EFRI used an alternative
laboratory, CTF, during the quarter, because the Mill's usual contract laboratory, AWAL,
suffered a catastrophic fire and could not accept samples.
The corrective action specified in the third quarter report was to resume sending samples to
A W AL as soon as their laboratory was able. The fourth quarter samples were sent to A W AL
and all rinsate samples were nondetect for all analytes. As such the coiTective action is deemed
closed and no further actions are required.
7.0 CONCLUSIONS AND RECOMMENDATIONS
As per the CAP, the current quarter is the fifth quarter that hydraulic capture associated with
nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 was evaluated. Water level
monitoring indicates that the apparent combined capture of the nitrate and chloroform pumping
systems is similar to and slightly larger than to last quarter. Capture associated with nitrate
pumping wells is developing and 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 will
require 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 will also be influenced by the perched groundwater mound and the apparently
anomalously low water level at TWN-7.
CuiTent pumping is likely sufficient to eventually capture the entire nitrate plume upgradient of
TW4-22 and TW4-24. Pumping during the current quarter is approximately the same as to a
factor of 2.1 times greater than the estimated pre-pumping ('background') rate of perched water
flow through the nitrate plume. Because the pre-pumping flow calculations likely overestimate
the new 'background' conditions caused by reduced recharge from the northern wildlife ponds,
and because the average plume hydraulic conductivity estimate from the low end of the
calculated range is likely to be more representative of actual conditions, nitrate pumping may
exceed flow through the plume by a factor greater than 2.1.
28
Fourth quarter, 2014 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 MW-26, MW-27, MW-31, TW4-10, TW4-16, TW4-
19, TW4-20, TW4-21, TW4-22, TW4-25, TWN-2, and TWN-4. The concentrations in wells
MW-11, MW-25, and MW-32 remained non-detect.
Of the wells showing changes in concentration greater than 20%, MW-26, TW4-19, and TW4-20
are chloroform pumping wells; and TW4-22, TW4-25 and TWN-2 are nitrate pumping wells.
TW4-10 and TW4-16 are located adjacent to chloroform pumping well MW-26; TW4-21 is
located adjacent to chloroform pumping well TW4-19; and TWN-4 is located between the
northern wildlife ponds and nitrate pumping wells TW4-25 and TWN-2. Nitrate concentration
fluctuations at pumping wells and adjacent wells likely result in part from the effects of
pumping. Concentrations at TW4-21 are also influenced by its location near the eastern nitrate
and northern chloroform plume boundaries. MW -31 is located in the downgradient portion of the
nitrate plume and is expected to be influenced by changes in upgradient pumping at nitrate
pumping wells TW4-22 and TW4-24 and chloroform pumping wells MW-26, TW4-19 and
TW4-20.
The nitrate concentration at TW 4-21 increased from 7.1 mg/L last quarter to 10 mg/L this
quarter, bringing it again just within the nitrate plume boundary. The nitrate concentration in
nitrate pumping well TW4-25 decreased from approximately 1.6 mg/L last quarter to 1.0 mg/L
this quarter. The nitrate concentrations in chloroform pumping wells MW-26, TW4-19, and
TW4-20 increased from approximately 0.7 mg/L, 1.6 mg/L and 4.3 mg/L, respectively, to
approximately 1.1 mg/L, 4.7 mg/L, and 7.7 mg/L. The chloroform concentration at nitrate
pumping well TW4-24 decreased from 76.3 f!g/L to 25.8 !!giL. The decrease at TW4-24 pushed
the chloroform plume boundary back to the east of TW4-24; last quarter, a chloroform
concentration increase from 62.7 f!g/L to 76.3 f!g/L moved the chloroform plume boundary to
the west of TW4-24. Chloroform changes at TW4-22 and TW4-24 are likely in response to the
start-up of nitrate pumping in the first quarter of 2013 and are affected by the presence of
historically high chloroform concentrations at adjacent, cross-gradient well TW4-20.
Increases in nitrate concentrations at wells within the nitrate plume since the last quarter have
resulted in a slight expansion of the plume area. 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). MW-25, MW-
26, MW-32, TW4-16, TW4-19, TW4-20, 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 increased from 13.8 mg/L to 16.2 mg/L and nitrate in MW-31 increased from 15.2 mg/L
to 20.9 mg/L. Based on the concentration data at MW-5, MW-11, MW-30, and MW-31, the
nitrate plume is under control.
29
Chloride has been relatively stable at MW-30 but is 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.
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 have been collected (starting with the first
quarter of 2013), a regression trend line is to be applied to the quarterly mass estimates and
evaluated. The trend line is then to be updated quarterly and reevaluated as additional quarters of
data are collected. As the current quarter constitutes the eighth quarter as specified in the CAP,
the mass estimates were plotted and a regression line fitted to the data, as shown in Figure M.1 of
Tab M. The fitted line shows a decreasing trend in the mass estimates.
The influence of individual wells on the mass estimates was evaluated qualitatively and
quantitatively as discussed in Section 4.3. The results of the visual and quantitative analyses
indicate that variations in plume mass estimates can be expected to depend primarily on
variations in data from TWN-2. Wells TW4-22, TW4-24, and MW-31 (not necessarily in that
order) are collectively the next most important with regard to influence on the mass estimates
During the current quarter, a total of approximately 109 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 109 lb removed during the current quarter, approximately 93 lb, (or 85 % ), 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 was calculated as 34,370 lb which was larger than the mass estimate during the
previous quarter (24,140 lb) by 10,230 lb or 42 %. This difference results from higher nitrate
concentrations measured in most wells within the plume and the resulting increased areal extent
this quarter compared to last quarter
Nitrate concentrations outside the nitrate plume exceed 10 mg/L at a few locations: TW4-12
(16.1 mg/L), TW4-26 (12.3 mg!L), TW4-27 (28.2 mg/L), and TW4-28 (16.5 mg/L). All these
30
wells are located southeast of the nitrate plume as defined in the CAP and all are separated from
the plume by wells having nitrate concentrations that are either non-detect, or, if detected, are
less than 10 mg!L. Concentrations at TW4-26, TW4-27 and TW4-28 are within 20% of their
concentrations during the previous quarter, while the concentration at TW4-12 increased more
than 20%, from approximately 13 mg/L to 16 mg/L. From the third quarter of 2013 through the
second quarter of 2014, nitrate concentrations at TW4-10 and TW4-18 exceeded 10 mg!L.
Although last quarter, nitrate concentrations at both TW4-10 and TW4-18 decreased to 9.8 mg!L,
both are again above 10 mg/L this quatter. Elevated nitrate concentrations at these wells are
associated with the chloroform plume, and both are within the capture zone of the chloroform
pumping system. Elevated nitrate at TW4-12, TW4-26, TW4-27, and TW4-28 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 nmthern wildlife
ponds. However, decreasing nitrate concentrations at most wells in the vicinity of TW 4-18 over
the previous three quarters after a previously increasing trend (interrupted in the first quarter of
2014) suggest that conditions in this area have stabilized.
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.
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 DRC 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.

RE: 4th Quarter Chloroform 2014
Dear Garrin Palmer: Lab Set ID: 1410353
American West Analytical Laboratories received 21 sample(s) on 10/24/2014 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, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope documents are available upon request. lfyou 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 "Rep01ting 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,
