1.0 INTRODUCTION
This is the Routine Groundwater Monitoring Report, as required under Part I.F .1 of State
of Utah Groundwater Discharge Permit No. UGW370004 (the "GWDP") for the third
quarter of 2023 for Energy Fuels Resources (USA) Inc's. ("EFRI's") White Mesa
Uranium Mill (the "Mill"). As required under Parts I.E.1, I.E.2, I.E.3, and I.E.5 of the
GWDP, this Report includes recorded field measurements and laboratory analyses for
well monitoring conducted during the quarter.
2.0 GROUNDWATER MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of groundwater monitoring wells, piezometers, ex1stmg
wells, chloroform contaminant investigation wells and nitrate contaminant investigation
wells is attached under Tab A. Groundwater samples and measurements were taken
during this reporting period, as discussed in the remainder of this section.
2.1.1 Groundwater Compliance Monitoring
Groundwater samples and field measurements collected during the quarter included both
quarterly and accelerated monitoring. Accelerated monitoring is discussed below in
Section 2.1.2. In this report, samples classified as being collected quarterly include those
wells which are routinely sampled every quarter as well as semi-annual wells which are
sampled on an accelerated quarterly schedule due to exceedances reported in previous
quarterly reports. Wells which are sampled routinely every quarter were analyzed for the
parameters listed in Table 2 and Part I.E.1.d) 2)ii of the GWDP dated March 8, 2021.
The semi-annual wells which have been accelerated to quarterly are analyzed only for
those parameters which exceeded the Groundwater Compliance Limits ("GWCLs") in
Table 2 described in previous reports and Exceedance Notices.
Table 1 of this report provides an overview of wells sampled during the current period,
along with the required sampling frequency applicable to each well during the current
monitoring period, the date samples were collected from each well, and the date(s)
analytical data were received from the contract laboratory(ies). Table 1 also indicates
which sample numbers are associated with the required duplicates.
2.1.2 Accelerated Groundwater Monitoring
Accelerated monthly sampling was also performed ( quarterly wells accelerated to
monthly), and results reported, for the wells indicated in Table I. The accelerated
sampling frequency, analyte list and well list were determined based on the previous
analytical results as shown in Table 2 and previous Exceedance Notices.
1
As a result of the issuance of a revised GWDP on March 8, 2021, which sets revised
GWCLs, requirements to perform accelerated monitoring under Part LG.I of the previous
GWDP ceased effective on March 8, 2021, and the effect of the issuance of the revised
GWDP was to create a "clean slate" for constituents in some wells going forward. The
GWCLs for some constituents were not 'reset" and continued on an accelerated sampling
frequency as shown on Table 2.
Table 1 provides an overview of the wells sampled for the accelerated monthly program
along with the routine sampling frequency as well as the accelerated sampling frequency,
the date samples were collected from each well, the associated duplicates and the date(s)
which analytical data were received from the contract laboratory(ies ).
2.1.3 Background Well Monitoring
Monitor wells MW-38, MW-39, and MW-40 were installed in the first quarter 2018
pursuant to the GWDP Part 1.H.2 and quarterly sampling commenced in fourth quarter
2018. The GWDP Part l.H.3 requires the completion of a background report for each of
these wells after the completion of 8 quarters of sampling. The background reports and
resultant Groundwater Compliance Limits ("GWCLs") were calculated based on eight
statistically valid data points.
The background report for wells MW-38, MW-39 and MW-40 was submitted to
DWMRC on March 4, 2021. EFRl submitted errata pages by letter dated June 7, 2021
based on the DWMRC review comments. The Background Report for MW-38, MW-39
and MW-40 was approved by DWMRC by letter dated June 16, 2021. MW-38, MW-39
and MW-40 will continue to be sampled on a quarterly basis until such time as these
wells are included in the GWDP.
Monitor Well MW-41 B was installed in the second quarter 2023 and quarterly sampling
commenced in the third quarter 2023. The GWDP requires the completion of a
background report for wells after the completion of 8 quarters of sampling. A
background report will be completed after the completion of 8 quarters of sampling or
when 8 data statistically valid data points are available for each analyte specified in Table
2 of the GWDP.
The analytical results for MW-38, MW-39, MW-40, and MW-41B for this period are
included in Tab E.
2.1.4 Parameters Analyzed
Routine quarterly groundwater monitoring samples were analyzed for the parameters
listed in Table 2 and Part I.E.1.d) 2) ii of the GWDP. The accelerated monitoring
samples were analyzed for a more limited and specific parameter list as shown in Table 2.
2
2.1.5 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant
to Part I.E.3 of the GWDP:
• The groundwater monitoring wells (including general monitoring wells, quarterly
and semi-annual monitoring wells, and (MW-34).
• Existing monitoring well MW-4 and the temporary chloroform investigation
wells.
• Piezometers -P-1, P-2, P-3A, P-4 and P-5.
• Nitrate monitoring wells.
• The DR piezometers which were installed during the Southwest Hydrogeologic
Investigation.
• In addition to the above, depth to water measurements are routinely observed in
conjunction with sampling events for wells sampled during quarterly and
accelerated efforts, regardless of the sampling purpose.
Water 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 D.
2.2 Field Data
Attached under Tab B are copies of field data sheets recorded in association with the
quarterly effort for the groundwater compliance monitoring wells referred to in paragraph
2.1.1, above. Sampling dates are listed in Table 1.
Attached under Tab C, are copies of field data sheets recorded in association with the
accelerated monthly monitoring sampling efforts, referred to in paragraph 2.1.2, above.
Sampling dates are listed in Table 1.
2.3 Laboratory Results -Quarterly Sampling
2.3.1 Copy of Laboratory Results
Analytical results are provided by two contract analytical laboratories: GEL and
Chemtech-Ford ("CTF").
Table 1 lists the dates when analytical results were reported to the Director, Regulatory
Compliance for each well.

Results from analysis of samples collected under the GWDP (i.e., regular quarterly and
accelerated semi-annual samples) are provided in Tab E. Also included under Tab E are
the results of analyses for duplicate samples as identified in Table 1.
2.3.2 Regulatory Framework and Groundwater Background
Under the GWDP, background groundwater quality has been determined on a well-by-
well basis, as defined by the DWMRC-approved flowchart included in the Revised
Background Groundwater Quality Report: Existing Wells for Denison Mines (USA)
Corp. 's White Mesa Uranium Mill Site, San Juan County, Utah. GWCLs that reflect this
background groundwater quality have been set for compliance monitoring wells except
MW-38, MW-39, and MW-40. As discussed in Section 2.1.3 above, EFRI previously
submitted the background report for MW-38, MW-39, and MW-40.
Exceedances of the GWCLs during the preceding quarter determined the accelerated
monthly monitoring program implemented during this quarter as noted in Tables 1 and 2
as modified under the renewed GWDP.
As a result of the issuance of the GWDP on March 8, 2021, which sets revised GWCLs,
requirements to perform accelerated monitoring under Part I.G. l of the previous GWDP
ceased effective on March 8, 2021, and the effect of the issuance of the revised GWDP
was to create a "clean slate" for constituents in some wells going forward. The GWCLs
for some constituents were not 'reset" and continued on an accelerated sampling
frequency as shown on Table 2.
Exceedances of the GWCLs for this quarter are listed in Table 2 for sampling required
under the GWDP. Accelerated requirements resulting from this quarter are highlighted
for ease of reference. Table 3 documents the accelerated sampling program since the
issuance of the March 8, 2021 GWDP.
It should be noted, however, that, because the GWCLs have been set at the mean plus
second standard deviation, or the equivalent, un-impacted groundwater would normally
be expected to exceed the GWCLs approximately 2.5% of the time. Therefore,
exceedances are expected in approximately 2.5% of sample results, and do not
necessarily represent impacts to groundwater from Mill operations. In fact, more frequent
sampling of a given analyte will increase the number of exceedances due to statistical
variation and not due to Mill activity. Additionally, given the slow velocity of
groundwater movement, accelerated sampling monthly may result in resampling of the
same water and may lead to repeat exceedances for accelerated constituents not due to
Mill activities, but due to repeat sampling of the same water.
2.4 Laboratory Results -Accelerated Monitoring
2.4.1 Copy of Laboratory Results
4
Results from analysis of samples collected for the monthly accelerated sampling (i.e.
quarterly accelerated to monthly) are provided in Tab F. Also included under Tab Fare
the results of analyses for duplicate samples for this sampling effort, as identified in
Table 1.
2.4.2 Regulatory Framework and Groundwater Background
As a result of the issuance of a revised GWDP on March 8, 2021, which sets revised
GWCLs for some constituents, requirements to perform accelerated monitoring under
Part I.G.1 of the previous GWDP for certain constituents ceased effective March 8, 2021,
and the effect of the issuance of the revised GWDP was to create a "clean slate" for
certain constituents in a limited list of wells going forward.
This means that accelerated monitoring during this quarter was required under the GWDP
for only those constituents that exceeded the GWCLs since March 8, 2021.
2.4.3 Compliance Status
Analytes that have exceeded the GWCLs for this quarter as set forth in the GWDP are
summarized in Table 2. The analytes which exceeded their respective GWCLs during the
quarter will be sampled on an accelerated schedule as noted in Table 2. Table 3
summarizes the results of the accelerated sampling program since the March 8, 2021
GWDP for the reasons stated in Section 2.3.2 above.
Part I.G.4 c) of the GWDP states, with respect to exceedances of GWCLs, "The
Permittee shall prepare and submit within 30 calendar days to the Director a plan and a
time schedule for assessment of the sources, extent and potential dispersion of the
contamination, and an evaluation of potential remedial action to restore and maintain
groundwater quality to insure that Permit limits will not be exceeded at the compliance
monitoring point and that DMT or BAT will be reestablished." EFRI submits an
Exceedance Notice quarterly and the summary in the Exceedance Notice includes, for
each exceedance, a brief discussion of whether such a plan and schedule is required at
this time in light of other actions currently being undertaken by EFRl. The determination
of whether a Plan and Time Schedule is required is based on discussions with DWMRC
Staff in teleconferences on April 27 and May 2, 2011 and the constituents covered by
previously submitted Source Assessment Reports.
2.5 Depth to Groundwater and Water Table Contour Map
As stated above, a listing of groundwater level readings for the quarter ( shown as depth to
groundwater in feet) is included under Tab D. The data from Tab D has been interpreted
(kriged) and plotted in a water table contour map, provided under Tab H.
The water table contour map provides the location and identity of the wells and
piezometers for which depth to groundwater is recorded. The groundwater elevation at
each well and piezometer, measured in feet above mean sea level, and isocontour lines to
5
delineate groundwater flow directions observed during the quarter's sampling event are
displayed on the map.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The Mill Director, Regulatory Compliance performed a QA/QC review to confirm
compliance of the monitoring program with requirements of the Groundwater Monitoring
Quality Assurance Plan ("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 quality control 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 laboratory data QA/QC are discussed in
Sections 3.4.4 through 3.4.9 below.
The Analytical Laboratories have 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 COC and Analytical
Request Record forms for each set of Analytical Results, follow the analytical results
under Tabs E and F. Review of the laboratory QA/QC information is provided under Tab
G.
3.1 Field QC Samples
The following field 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:
Two duplicate samples weres collected during quarterly sampling as indicated in Table 1.
The QC samples were sent blind to the analytical laboratory and analyzed for the same
parameters as permit-required samples.
One duplicate sample was collected during each of the monthly sampling events as
indicated in Table 1. The QC samples were sent blind to the analytical laboratory and
analyzed for the same accelerated parameters as the parent sample.
One trip blank was provided by CTF and returned and analyzed with the quarterly
monitoring samples.
One trip blank for each of the monthly accelerated sample events was provided by CTF
and returned and analyzed with the accelerated monthly monitoring samples.
Rinsate samples were not collected during the quarter because equipment used during
sample collection was dedicated and did not require decontamination. All wells except
6
MW-20, MW-37 and MW-38 have dedicated pumps for purging and sampling and as
such no rinsate blanks samples are required. MW-20, MW-37 and MW-38 were purged
and sampled with a disposable bailer and no rinsate blank was required. A deionized
field blank was not required because equipment decontamination was not required and
deionized water was not used during this sampling event.
3.2 Adherence to Mill Sampling SOPs
On a review of adherence by Mill personnel to the existing sampling SOPs, the Director,
Regulatory Compliance observed that QA/QC requirements established in the QAP were
met and that the SOP's were implemented as required.
3.3 Analyte Completeness Review
Analyses required by the GWDP for the quarterly and semi-annual wells were performed.
The accelerated sampling for the semi-annual wells (semi-annual to quarterly) was
completed as required by the GWDP and as shown in Tables 2 and 3. The accelerated
quarterly sampling (quarterly to monthly) required for this quarter, as shown in Tables 2
and 3, was performed as required.
The monthly accelerated sampling program shown on Tables 2 and 3 is required as a
result of exceedances in quarterly well monitoring results reported in previous quarters.
3.4 Data Validation
The QAP and GWDP identify the data validation steps and data quality control checks
required for the groundwater monitoring program. Consistent with these requirements,
the Director, Regulatory Compliance completed the following evaluations: a field data
QA/QC evaluation, a receipt temperature check, a holding time check, an analytical
method check, a reporting limit check, a trip blank check, a QA/QC evaluation of routine
sample duplicates, a QA/QC evaluation of accelerated sample duplicates, a gross alpha
counting error evaluation and a review of each laboratory's reported QA/QC information.
Each evaluation is discussed in the following sections. Data check tables indicating the
results of each test are provided under Tab G.
3.4.1 Field Data QA/QC Evaluation
The Director, Regulatory Compliance performs a review of 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 the stability
of the following field parameters (based upon the purging method chosen): specific
conductance, pH, temperature, redox potential, dissolved oxygen ("DO") and turbidity.
Stability of field parameters and well sampling techniques are dependent on the purging
technique employed. Review of the Depth to Water data confirms that depth
7
measurements were conducted within a five-day period. The results of this quarter's
review are provided in Tab G.
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
During both the quarterly sampling event and the two monthly events, the purging
technique used was two casing volumes with stable field parameters (pH, Conductivity,
Redox, temperature, DO, and turbidity) except for the following wells that were purged
to dryness: MW-37, MW-38, and MW-41B.
MW-37, MW-38, and MW-41B conformed to the QAP requirement for sampling low
yield wells which includes the collection of three field parameters (pH, specific
conductance ["conductivity"] and temperature) immediately prior to and immediately
following sample collection. Stabilization of pH, conductivity and temperature were
within the 10% RPD required by the QAP. MW-37, MW-38, and MW-41B were purged
to dryness and the low yield sampling procedures were used for the collection of field
parameters. Stabilization of pH, conductivity and temperature were within the 10% RPD
required by the QAP for well MW-37, MW-38, and MW-41B.
Additionally, two casing volumes were not purged from MW-26, prior to sampling
because MW-26 is a continuously pumped well. If a well is continuously pumped, it is
pumped on a set schedule per the remediation plan and is considered sufficiently
evacuated to immediately collect a sample; however, if a pumping well has been out of
service for 48 hours or more, EFRJ follows the purging requirements outlined in
Attachment 2-3 of the QAP.
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 two consecutive
measurements. 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.
• Turbidity measurements were less than 5 NTU for the quarterly and semi-annual
wells except MW-24, MW-24A, MW-25, MW-29, and MW-32. Per the QAP,
Attachment 2-3, turbidity measurements prior to sampling were within a 10%
8
RPD for the quarterly and semi-annual wells.
• Turbidity measurements were less than 5 NTU for the accelerated sampling wells
except MW-25 and MW-26 in the August event and MW-25 in the September
event. Per the QAP, Attachment 2-3, turbidity measurements prior to sampling
were within a 10% RPD for the quarterly and semi-annual wells. Turbidity
measurements prior to sampling were within a 10% RPD for the accelerated
sampling wells.
The other field parameters (conductance, pH, redox potential, DO, and temperature) for
the wells were within the required RPD for the quarterly, semi-annual and accelerated
sampling.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water for the quarterly, semi-annual and accelerated
sampling programs to the nearest 0.01 foot.
EFRI's letter to DWMRC of March 26, 2010 discusses further why turbidity does not
appear to be an appropriate parameter for assessing well stabilization. In response to
DWMRC's subsequent correspondence dated June 1, 2010 and June 24, 2010, EFRI has
completed a monitoring well redevelopment program. The redevelopment report was
submitted to DWMRC on September 30, 2011. DWMRC responded to the
redevelopment report via letter on November 15, 2012. Per the DWMRC letter dated
November 15, 2012, the field data generated this quarter are compliant with the turbidity
requirements of the approved QAP.
3.4.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample
holding time checks are provided under Tab G. The samples were received and analyzed
within the required holding time.
All accelerated samples were received and analyzed within the required holding time.
3.4.3 Receipt Temperature Evaluation
COC sheets were reviewed to confirm compliance with the QAP requirement in Table 1
that samples be received at 6°C or lower. Sample receipt temperature checks are
provided under Tab G. The quarterly, semi-annual and accelerated samples were
received within the required temperature limit.
As noted in Tab G, samples for gross alpha analyses were shipped without using ice. Per
Table 1 in the approved QAP, samples submitted for gross alpha analyses do not have a
sample temperature requirement.

3.4.4 Analytical Method Checklist
The analytical methods reported by both laboratories were checked against the required
methods specified in the QAP. Analytical method check results are provided in Tab G.
The review indicated that the quarterly, semi-annual and accelerated samples were
analyzed in accordance with Table 1 of the QAP.
3.4.5 Reporting Limit Evaluation
The analytical method RLs reported by both laboratories were checked against the RLs
specified in the QAP Table 1. RL evaluations are provided in Tab G. The analytes were
measured and reported to the required RLs except that several sets of quarterly, semi-
annual and accelerated sample results had the RL raised for at least one analyte due to
matrix interference and/or sample dilution as noted in Section 3.4.9. In all cases the
reported value for the analyte was higher than the increased RL.
3.4.6 Trip Blank Evaluation
The trip blank results were reviewed to identify any VOC sample contamination which is
the result of sample handling and shipment. Trip blank evaluations are provided in Tab
G. The trip blank results associated with the quarterly, semi-annual and accelerated
samples were all nondetect for VOCs.
3.4. 7 QA/QC Evaluation for Routine 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 detection limit. This standard is based on the EPA
Contract Laboratory Program National Functional Guidelines for Inorganic Data Review,
February 1994, 9240.1-05-01 as cited in the QAP. The RPDs are calculated for the
duplicate pairs for all analytes regardless of whether or not the reported concentrations
are greater than 5 times the required detection limits; however, data 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 additional duplicate information is provided for
information purposes.
Field duplicate sample results were assessed as required by the QAP. Duplicate results
were within the acceptance limits specified in the QAP. Field duplicate results are shown
in Attachment G.
The duplicate results were within a 20% RPD in the accelerated samples. Results of the
RPD test are provided under Tab G.
3.4.8 Radiologies Counting Error and Duplicate Evaluation
Section 9 .14 of the QAP requires that when gross alpha results are reported with an
activity equal to or greater than the GWCL the counting variance shall be equal to or less
than 20% of the reported activity concentration. An error term may be greater than 20%
of the reported activity concentration when the sum of the activity concentration and
error term is less than or equal to the GWCL. The quarterly and semi-annual radiologic
sample results met the counting error requirements specified in the QAP except as noted
in Tab G. The results for MW-26 did not meet the requirement that the counting error be
equal to or less than 20% of the reported activity concentration, likely because the
reported concentrations are very near the RL. As stated above the error term may be
greater than 20% of the reported activity concentration when the sum of the activity
concentration and error term is less than or equal to the GWCL. MW-26 passed the
secondary check.
Section 9.4 of the QAP also requires a comparability check between the sample and field
duplicate sample results utilizing the formula provided in the text.
Results of quarterly and semi-annual, radiologic sample QC are provided under Tab G.
The quarterly and semi-annual sample results met the duplicate counting error
requirements specified in the QAP.
3.4.9 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 Director, Regulatory Compliance 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 under Tab G. The lab QA/QC results from both GEL and CTF samples for
compounds regulated under the GWDP met these requirements.
The check samples included at least the following: a method blank, a laboratory control
spike ("LCS"), a matrix spike ("MS") and a matrix spike duplicate ("MSD"), or the
equivalent, where applicable. It should be noted that:
• Laboratory fortified blanks are equivalent to LCSs.
• Laboratory reagent blanks are equivalent to method blanks.
• Post digestion spikes are equivalent to MSs.
• Post digestion spike duplicates are equivalent to MSDs.
11
• Laboratory Duplicates are equivalent to MSDs.
The qualifiers, and the corresponding explanations reported in the QA/QC Summary
Reports for the check samples for the analytical methods were reviewed by the QA
Manager.
The QAP, Section 8.1.2 requires that a 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 requirements in the QAP to
analyze a 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 quarterly and semi-annual samples
were within acceptable laboratory limits for the regulated compounds except as indicated
in Tab G. The data recoveries and RPDs which are outside the laboratory established
acceptance limits do not affect the quality or usability of the data because the recoveries
and RPDs above or below the acceptance limits are indicative of matrix interference most
likely caused by other constituents in the samples. Matrix interferences are applicable to
the individual sample results only. The requirement in the QAP to analyze a MS/MSD
pair with each analytical batch was met and as such the data are compliant with the QAP.
The information from the Laboratory QA/QC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for the accelerated samples were within
acceptable laboratory limits for the regulated compounds except as indicated in Tab G.
The data recoveries and RPDs which are outside the laboratory established acceptance
limits do not affect the quality or usability of the data because the recoveries and RPDs
above or below the acceptance limits are indicative of matrix interference most likely
caused by other constituents in the samples. Matrix interferences are applicable to the
individual sample results only. The requirement in the QAP to analyze a MS/MSD pair
with each analytical batch was met and as such the data are compliant with the QAP.
The QAP specifies that surrogate compounds shall be employed for all organic analyses
but the QAP does not specify acceptance limits for surrogate recoveries. The information
from the Laboratory QA/QC Summary Reports indicates that the surrogate recoveries for
the quarterly and accelerated samples were within acceptable laboratory limits for the
surrogate compounds except as indicated in Tab G. The surrogate 4-Bromofluorobenzene
was above the acceptance limit set by the laboratory. A high recovery is indicative of a
high bias to the VOC samples.
The information from the Laboratory QA/QC Summary Reports indicates that the LCS
recoveries for the quarterly samples were within acceptable laboratory limits for the LCS
12
compounds as noted in Tab G.
The information from the Laboratory QA/QC Summary Reports indicates that the LCS
recoveries for the accelerated samples were within acceptable laboratory limits for the
LCS compounds as noted in Tab G.
The QAP, Section 8.1.2 requires that each analytical batch shall be accompanied by a
method blank. The analytical batches routinely contain a blank, which is a blank sample
made and carried through all analytical steps. For the Mill samples, a method blank was
prepared for the analytical methods. Per the approved QAP Section 9.1.3, contamination
detected in analysis of method blanks will be used to evaluate any analytical laboratory
contamination of environmental samples. The QAP states that non-conformance
conditions will exist when contaminant levels in the samples(s) are not an order of
magnitude greater than the blank result. The method blanks for the quarterly samples
reported no detections. Method blank results are included in Tab E and Tab F.
Laboratory duplicates are completed by the analytical laboratories as required by the
analytical method specifications. Acceptance limits for laboratory duplicates are set by
the laboratories. The QAP does not require the completion of laboratory duplicates or the
completion of a QA assessment of them. EFRI reviews the QC data provided by the
laboratories for completeness and to assess the overall quality of the data provided.
Duplicate results are included in the analytical data.
4.0 CORRECTIVE ACTION REPORT
There are no corrective actions required during the current monitoring period.
4.1 Assessment of Corrective Actions from Previous Period
No corrective actions were identified in the previous report.
5.0 TIME CONCENTRATION PLOTS
Time concentration plots for each monitoring well for the following constituents:
chloride, fluoride, sulfate, and uranium, are included under Tab I. The data points
collected to date are reflected on the plots.
Time concentration plots included with quarterly groundwater reports prior to and
including first quarter 2012 did not include data that were determined to be outliers using
the statistical methods used for the background determinations at the Mill. Based on
conversations with DWMRC, all of the data have been included in the quarterly time
concentration plots since first quarter 2012.
13
6.0 ELECTRONIC DATA FILES AND FORMAT
EFRI has provided to the Director electronic copies of the laboratory results from
groundwater quality monitoring conducted during the quarter in Comma Separated
Values format, from the analytical laboratories. A copy of the transmittal e-mail is
included under Tab J.
