ANNUAL SEEPS AND SPRINGS SAMPLING REPORT
1.0 INTRODUCTION
This is the 2023 Annual Seeps and Springs Sampling Report for the Energy Fuels Resources
(USA) Inc. ("EFRI") White Mesa Mill (the "Mill"), as required under Part I.F.7 of the Mill's
State of Utah Groundwater Discharge Permit No. UGW370004 (the "Permit") and the Mill's
Sampling and Analysis Plan for Seeps and Springs, Revision: 2, July 8, 2016 (the "Sampling
Plan").
The Sampling Plan for Seeps and Springs was revised in July 2016 to incorporate changes
requested by the Division of Waste Management and Radiation Control ("DWMRC"). The
Sampling Plan/or Seeps and Springs, Revision: 2, July 8, 2016 was approved by DWMRC by
letter dated August 8, 2016.
2.0 SAMPLING EVENTS
Seeps and springs which were identified near the Mill in the 1978 Environmental Report (Plate
2.6-10, Dames and Moore, January 30, 1978) are to be sampled annually in accordance with the
Sampling Plan and Part I.E.6 of the Permit. The Sampling Plan specifies the following sample
locations: Corral Canyon Seep, Corral Springs, Ruin Spring, Cottonwood Seep, Westwater Seep
and Entrance Spring (also referred to as Entrance Seep).
2.2 2023 Sampling
In accordance with the Permit and the Sampling Plan, DWMRC was notified of the annual
sampling events. On March 30, 2023 EFRI collected the Westwater Seep sample. On May 16,
2023, EFRI collected seeps and springs samples from Cottonwood Seep, Ruin Spring, Entrance
Seep, and Back Spring ( duplicate of Ruin Spring). The DWMRC representative was present for
May 16, 2023 sampling event and collected a "split" sample from the EFRI sampling equipment,
using sample containers he provided. Corral Canyon Seep and Corral Springs were dry during
the annual sampling event.
2.3 Repeat Visits to Dry Seeps and Springs.
Corral Canyon Seep and Corral Springs, were visited once per calendar quarter in 2023. The
visits were conducted in March, May, July and November 2023. Corral Canyon Seep and Corral
Springs, were dry during all of the visits, could not be sampled, and did not warrant development
attempts with limited hand tool excavation at that time.
2.4 Sampling Procedures
Samples were collected and analyzed for the parameters listed in Table 2 of the Permit.
Samples were collected from the locations indicated in Table 1. Sampling procedures for each
seep or spring are determined by the site location and access.
The DWMRC-approved sampling procedures for seeps and springs at the Mill are contained in
the Sampling Plan. Samples collected under this plan were collected either by direct collection
which involves collecting the sample directly into the sample container from the surface water
feature or from spring out-flow, or by using a stainless steel ladle to collect water until a
sufficient volume is contained in the ladle for transfer to the sample bottle. Filtered parameters
are pumped through a 0.45 micron filter prior to delivery to the sample bottle.
Ruin Spring
In the case of Ruin Spring, sample bottles for the analytes collected during the May sampling
event (except gross alpha and heavy metals) were filled directly from the spring out-flow which
is a pipe. Samples for heavy metals and gross alpha were collected by means of a peristaltic
pump and delivered directly to the sample containers through a 0.45 micron filter. The
appropriate preservatives for the analytical technique were added to the samples.
Westwater Seep
Westwater Seep, was "developed" prior to the sampling event by Field Personnel. Development
was completed by removing surrounding ' vegetation and clearing the sampling location in the
spring or seep area. All of the sample containers were filled by means of a peristaltic pump and
delivered directly to the sample containers. Samples for heavy metals and gross alpha were
collected by means of a peristaltic pump and delivered directly to the sample containers through
a 0.45 micron filter. The appropriate preservatives for the analytical technique were added to the
samples.
Cottonwood Seep and Entrance Spring
Cottonwood Seep and Entrance Spring were "developed" prior to the sampling event by Field
Personnel. Development was completed by removing surrounding vegetation and clearing the
sampling location in the spring or seep area. The sample containers were filled by means of a
peristaltic pump and delivered directly to the sample containers. In the case of the samples for
heavy metals and gross alpha, the samples were delivered by a peristaltic pump directly to the
sample containers through a 0.45 micron filter. The samples were preserved by the addition of
the appropriate preservative for the analytical technique.
The tubing on the peristaltic pump that comes into contact with the sample water was disposed of
between each sampling. As a result, no equipment required decontamination, and no rinsate
samples were collected.
2.5 Field Data
Attached under Tab A are copies of the field data sheets recorded in association with the March
and May seeps and springs monitoring events. Photographic documentation of the sampling
sites is also included in Tab A. Sampling dates are listed in Table 1 and field parameters
collected during the sampling program are included in Tab B.
2
2.6 Field QC Samples
The field Quality Control ("QC") samples generated during the March and May sampling events
included one trip blank per shipment to each laboratory which received samples for VOCs. The
May sampling event included one duplicate to each laboratory which received samples for
VOCs. The duplicate samples (Back Spring) were submitted blind to the analytical laboratory.
As previously stated, no rinsate blanks were collected during this sampling event as only
disposable equipment was used for sample collection.
3.0 SEEPS AND SPRINGS SURVEY AND CONTOUR MAP
Part I.F.7(c) of the Permit requires that a water table contour map that includes the elevations for
each well at the facility and the elevations of the phreatic surfaces observed for each of the seeps
and springs sampled be submitted with this annual report. Tab C includes two contour maps.
The contour map labeled C-1 shows the water table without the water level data associated with
the dry ridge ("DR") investigation piezometers. The contour map labeled C-2 shows the water
table with the water level data associated with the DR investigation piezometers. It is important
to note that Cottonwood Seep is not included in any of the perched water level contouring,
because there is no evidence to establish a hydraulic connection between Cottonwood Seep and
the perched water system. Cottonwood Seep is located near the Brushy Basin
Member/Westwater Canyon Member contact, approximately 230 feet below the base of the
perched water system defined by the Burro Canyon Formation/Brushy Basin Member contact.
The stratigraphic position of Cottonwood Seep indicates that its elevation is not representative of
the perched potentiometric surface. Exclusion of the Cottonwood Seep from water level
contouring is consistent with previous submissions. The contour map includes the corrected
survey data from December 2009 as discussed below.
Part I.F. 7 (g) of the Permit requires that survey data for the seeps and springs be collected prior
to the collection of samples. DWMRC previously clarified that the requirement to submit survey
data applies only to the first sampling event and not on an annual basis. The December 2009 and
July 2010 seeps and springs survey data shown in Tab C will be used for reporting where seeps
and springs locations and elevations are relevant.
A full discussion of the survey data and the hydro geology of seeps and springs at the margins of
White Mesa in the vicinity of the Mill and the relationship of these seeps and springs to the
hydrogeology of the site, in particular to the occurrence of a relatively shallow perched
groundwater zone beneath the site, is contained in Hydrogeology of the Perched Groundwater
Zone and Associated Seeps and Springs Near the White Mesa Uranium Mill Site, dated
November 12, 2010, prepared by Hydro Geo Chem, Inc. and submitted to the Director on
November 15, 2010. Additional information is also contained in the Second Revision
Hydrogeology of the Perched Groundwater Zone in the Area Southwest of the Tailings Cells
White Mesa Mill Site, dated November 7, 2012, prepared by Hydro Geo Chem, Inc. and
submitted to the Director on November 7, 2012.

4.0 QUALITY ASSURANCE AND QUALITY CONTROL
4.1 Laboratory Results
Analytical results are provided by the Mill's two contract analytical laboratories GEL
Laboratories, Inc., ("GEL") and CHEMTECH-FORD Laboratories ("CTF").
The laboratories utilized during this investigation were certified under the Environmental Lab
Certification Program administered by UDEQ Bureau of Lab Improvement for the analyses they
completed.
The analytical data as well as the laboratory Quality Assurance ("QA")/QC summanes are
included under Tab D.
4.2 DATA EVALUATION
The Permit requires that the annual seeps and springs sampling program be conducted in
compliance with the requirements specified in the Mill's approved White Mesa Uranium Mill
Groundwater Monitoring Quality Assurance Plan ("QAP"), the approved Sampling Plan and the
Permit. To meet this requirement, the data validation completed for the seeps and springs
sampling program verified that the program met the requirements outlined in the QAP, the
Permit and the approved Sampling Plan. The Mill Director, Regulatory Compliance performed a
QA/QC review to confirm compliance of the monitoring program with requirements of the
Permit and 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 quality
control review of laboratory data methods and data. Identification of field QC samples collected
and analyzed is provided in Section 4.5.1. Discussion of adherence to the Sampling Plan is
provided in Section 4.3. Analytical completeness review results are provided in Section 4.4.
The steps and tests applied to check laboratory data QA/QC are discussed in Sections 4.5.1
through 4.5.9 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 Chain of Custody and Analytical Request
Record forms for each set of analytical results, follow the analytical results under Tab D. Results
of the review of the laboratory QA/QC information are provided under Tab E and discussed in
Section 4.5 below.
4.3 Adherence to Sampling Plan and Permit Requirements
On a review of adherence by Mill personnel to the Permit, the Director, Regulatory Compliance
observed that QA/QC requirements established in the Permit and the QAP were met and that the
requirements were implemented as required except, as noted below.
4
The Permit only requires the measurement of the field parameters pH, conductivity and
temperature. Field parameter measurements collected during this sampling event included pH,
conductivity, temperature, redox potential, turbidity, and dissolved oxygen ("DO").
4.4 Analyte Completeness Review
The analyses required by the Permit Table 2 were completed.
4.5 Data Validation
The QAP and the Permit identify the data validation steps and data quality control checks
required for the seeps and springs monitoring program. Consistent with these requirements, the
Director, Regulatory Compliance performed 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 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 E.
4.5.1 Field Data QA/QC Evaluation
The Director, Regulatory Compliance performs a review of field recorded parameters to assess
their adherence with QAP and Permit requirements. The assessment involved review of the Field
Data sheets. Review of the Field Data Sheets noted that the requirements for field data collection
were met.
4.5.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample holding
time checks are provided under Tab E. The samples were received and analyzed within the
required holding time.
4.5.3 Laboratory Receipt Temperature Check
Chain of Custody sheets were reviewed to confirm compliance with the sample receipt
requirements specified in the QAP. Sample receipt temperature checks are provided under Tab
E. The samples were received within the QAP required temperature limit.
4.5.4 Analytical Method Check
The analytical methods reported by both laboratories were checked against the required methods specified
in Table 1 of the QAP. Analytical method check results are provided in Tab E. The samples were
analyzed using the methods specified in the QAP.
5
4.5.5 Reporting Limit Evaluation
Reporting limits utilized by the laboratory were required to be equal to or lower than the
Groundwater Quality Standards ("GWQSs") set out in Table 2 of the Permit. For Total
Dissolved Solids ("TDS"), sulfate and chloride, for which Ground Water Quality Standards are
not set out in Table 2 of the Permit, reporting limits specified in Part 1.E.6.e ).(1) were used.
Those reporting limits are 10 mg/L for TDS, and 1 mg/L for Sulfate and Chloride. The analytical
method reporting limits reported by both laboratories were checked against the reporting limits
specified in the Permit. Reporting limit evaluations are provided in Tab E. All analytes were
measured and reported to the required reporting limits except the sample results that had the
reporting limit raised due to sample dilution necessary to accommodate the analyte
concentrations in the samples. In all cases the reported value for the analyte was higher than the
increased detection limit.
It is important to note that the CTF reported some analytes lower than the GWDP required limits
(equivalent to the GWQSs). All previous data were reported to the GWQS as required by the
GWDP. These lower RLs resulted in detections being reported starting in 2022 that have never
been reported before. These detections are not indicative of increasing analyte concentrations,
but are indicative of lower RLs and low level detections.
4.5.6 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 evaluation is provided in Tab E. The trip
blank results associated with the samples were less than the reporting limit for the VOCs.
4.5.7 QA/QC Evaluation for Sample Duplicates
Section 9.1.4 a) of the QAP states that the Relative Percent Difference ("RPD") 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 ( described as activities in the QAP) are less than 5 times the required detection
limit. This standard is based on the United Stated Environmental Protection Agency 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 the 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%. RPDs are also only
calculated when both the sample and the duplicate report a detection for any given analyte. If
only one of the pair reports a detection, the RPD cannot be calculated. The additional duplicate
information is provided for information purposes.
All duplicate results except for chloride in the Back Spring/Ruin Spring duplicate pair were
within 20% RPD. The chloride results were greater than 20% RPD. Per the approved QAP, a
separate corrective action for duplicate RPDs outside of acceptance limits has been developed.
The revised procedure for duplicate results outside of acceptance limits was implemented. The
6
corrective actions that were taken in accordance with the revised procedure are as follows: the
Director, Regulatory Compliance contacted the Analytical Laboratory and requested a review of
the raw data to assure that there were no transcription errors, and the data were accurately
reported. The laboratory noted that the data were accurate and reported correctly. Reanalysis was
not completed as the samples were out of holding time. There is no effect on the usability of the
data due to the duplicate results exceeding the comparability criteria the noncompliance was due
to matrix interferences. The duplicate evaluation is provided in Tab E.
4.5.8 Radiologies Counting Error
Section 9 .14 of the QAP requires that all gross alpha analysis reported with an activity equal to
or greater than the Groundwater Compliance Limits set out in the Permit (for the seeps and
springs samples the GWQS will be used), shall have a counting variance that is 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 GWQS.
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.
All radiological results were reported were non-detect and therefore within acceptance limits.
Results of routine radiologic sample QC are provided under Tab E.
4.5.9 Laboratory Matrix QC Evaluation
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 E. The lab QA/QC results from both GEL and CTF met these
requirements except as described below.
A number of the seeps and springs samples had the reporting limit raised due to matrix
interference and/or sample dilution. In all cases where the detection limit was increased, the
concentration for the analyte was higher than the increased detection limit.
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:
7
• 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.
• For method E900.1, used to determine gross alpha, a sample duplicate was used instead
ofaMSD.
The qualifiers, and the corresponding explanations reported in the QA/QC Summary Reports for
any of the check samples for any of the analytical methods, were reviewed by the Director,
Regulatory Compliance.
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 QAP requirement 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 each laboratory's 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/MSD
recoveries and the associated RPDs for the seeps and springs samples were within acceptable
laboratory limits except as noted in Tab E. The MS/MSD recoveries that were 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 QAPs 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 there were low
LCS recoveries in one analytical batch as indicated in Tab E.
A low LCS recovery for chloromethane were reported in analytical batch 23E1617. The data
were flagged in accordance with EPA protocols. The Chloromethane data are usable because
chloromethane, as well as other volatiles, are not frequently or historically detected and the non-
detects are likely accurate.
The QAP specifies that surrogate compounds shall be employed for all organic analyses, but the
QAP does not specify acceptance limits for surrogate recoveries. The analytical data associated
with the routine quarterly sampling met the requirement specified in the QAP. The information
from the Laboratory QA/QC Summary Reports indicates that the surrogate recoveries for the
seeps and springs samples were within acceptable laboratory limits for all surrogate compounds.
8
The QAP Section 8.1.2 requires that each analytical batch shall be accompanied by a reagent
blank. Contamination detected in analysis of reagent blanks/method blanks will be used to
evaluate any analytical laboratory contamination of environmental samples. The QAP specified
process for evaluation of reagent/method blanks states that nonconformance will exist when
blanks are within an order of magnitude of the sample results. The information from the
Laboratory QA/QC Summary Reports indicates that the reagent (method) blanks for the seeps
and springs samples were non-detect and were therefore within the acceptance criteria specified
in the QAP.
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. EFRl reviews the QC data provided by the laboratories for completeness
and to assess the overall quality of the data provided. Laboratory duplicate results are provided
in Tab D.
5.0 EVALUATION OF ANALYTICAL DATA
As previously stated, the samples were analyzed for the groundwater compliance parameters
found on Table 2 of the Permit. In addition to these laboratory parameters, the pH, temperature,
conductivity, (and although not required, redox, DO and turbidity) were measured and recorded
in the field.
5.1 Evaluation of Analytical Results
The results of the March and May sampling events show no evidence of Mill influence in the
water produced by the seeps and springs sampled. The lack of Mill influence on seeps and
springs is indicated by the fact that the parameters detected are within the ranges of
concentrations for the on-site monitoring wells and for available historic data for the seeps and
springs themselves. For those detected analytes, concentrations are shown in Tables 2A, 2B, 2C,
and 2D. The data are compared to available historic data for each seep and spring as well as to
on-site monitoring well data. Specific discussions about each seep or spring are included below.
5.1.1 Ruin Spring
No VOCs or radiologies were detected. Metals and major ions were the only analytes detected.
The metals detections were minimal with only calcium, magnesium, potassium, sodium,
chromium, manganese, mercury, molybdenum, nickel, selenium, uranium and vanadium having
positive detections. The major ions detected include· bicarbonate, chloride, fluoride, nitrate,
sulfate and TDS. A comparison of the 2009 through 2022 data to the 2023 data shows that the
concentrations of most detected analytes remained approximately the same with only minor
changes within the limits of normal analytical deviation. The RLs and the reported values for
chromium, manganese, mercury, molybdenum, nickel, and vanadium were below the GWDP
required RL as noted in Section 4.5.5. The reported values for bicarbonate, TDS, manganese,
mercury, nickel, selenium, and uranium increased slightly from the 2022 sample results and
remain below the upper range of historic background values of this location and/or below the
upper range of historic background values (where available) for the on-site monitoring wells.
9
The differences are not significant and are most likely due to normal fluctuations due to flow
rates or seasonal variations due to annual precipitation. Overall, the data reported for Ruin
Spring are typical for a surface water sample with no indication of Mill influence.
5.1.2 Cottonwood Spring
No VOCs or radiologies were detected. Metals and major ions were the only analytes detected.
The metals detections were minimal with calcium, magnesium, potassium, sodium, arsenic,
chromium, manganese, molybdenum, nickel, selenium, tin, uranium and vanadium having a
positive detection. The major ions detected include bicarbonate, chloride, fluoride, sulfate, and
TDS. A comparison of the 2009 through 2022 data to the 2023 data shows that the
concentrations of most detected analytes remained approximately the same with only minor
changes within the limits of normal analytical deviation. The RLs and the reported values for
arsenic, chromium, manganese, molybdenum, nickel, selenium, tin, and vanadium were below
the GWDP required RL as noted in Section 4.5.5. The reported values for TDS, bicarbonate,
calcium, arsenic, manganese, nickel, selenium and uranium increased from the 2022 sample
results, and remain below the upper range of historic background values of this location and/or
below the upper range of historic background values (where available) for the on-site monitoring
wells. The differences are not significant and are most likely due to normal fluctuations due to
flow rates or seasonal variations due to annual precipitation. Overall, the data reported for
Cottonwood Spring are typical for a surface water sample with no indication of Mill influence.
5.1.3 Westwater Seep
No VOCs or radiologies were detected. Metals and major ions were the only analytes detected.
The metals detections were minimal with calcium, magnesium, potassium, sodium, arsenic,
chromium, cobalt, iron, manganese, molybdenum, nickel, selenium, vanadium and uranium
having positive detections. The major ions detected include bicarbonate, chloride, fluoride,
sulfate, and TDS. A comparison of the historic data to the 2023 data shows that the
concentrations of most detected analytes remained approximately the same with only minor
changes within the limits of normal analytical deviation. The RLs and the reported values for
arsenic, chromium, cobalt, molybdenum, nickel, selenium, and vanadium were below the GWDP
required RL as noted in Section 4.5.5. The reported values for bicarbonate, TDS, calcium,
potassium, chloride, chromium, magnesium, molybdenum, sodium, sulfate, vanadium and
uranium increased from the 2022 sample results and the reported values remain below the upper
range of historic background values of this location and/or below the upper range of historic
background values (where available) for the on-site monitoring wells. The differences are not
significant and are most likely due to normal fluctuations due to flow rates or seasonal variations
due to annual precipitation. Overall, the data reported for Westwater Seep are typical for a
surface water sample with no indication of Mill influence.
5.1.4 Entrance Spring
No VOCs or radiologies were detected. Metals and major ions were the only analytes detected.
The metals detections were minimal with only calcium, magnesium, potassium, sodium, arsenic,
chromium, cobalt, iron, molybdenum, nickel, tin, uranium, vanadium, manganese and selenium
having positive detections. The major ions detected include bicarbonate, chloride, fluoride,
10
nitrate, sulfate, and TDS. A comparison of the 2009 through 2022 data to the 2023 data shows
that the concentrations of most detected analytes remained approximately the same with only
minor changes within the limits of normal analytical deviation. The RLs and the reported values
for arsenic, chromium, cobalt, molybdenum, nickel, and vanadium were below the GWDP
required RL as noted in Section 4.5.5. The reported values for calcium, chloride, magnesium,
nitrate, potassium, sodium, sulfate, TDS, bicarbonate, arsenic, cobalt, manganese, nickel,
selenium, tin, and uranium increased from the 2022 sample results. The detected concentrations
and the reported value remain below the upper range of historic background values of this
location and/or below the upper range of historic background values (where available) for the on-
site monitoring wells. As stated in Section 2.4 above Entrance Spring is "developed" prior to
the sampling event by Field Personnel. Development was completed the day prior to sampling
by removing surrounding vegetation and clearing the sampling location in the spring or seep
area. A shovel or trowel is used to dig a hole in the soil, which is allowed to fill with water. The
standing water was sampled. Field Personnel noted the area was muddy and there is livestock
activity in the area. The Entrance Spring sample data and constituent concentrations are likely
affected by the muddy site conditions and livestock activity in the sampling area.
Overall, the data reported for Entrance Spring are typical for a surface water sample with no
indication of Mill influence.

Work Order Report Narrative
The Total Dissolved Solids and TDS Ratio are biased high on sample 23E1617-02. The analysis could not be performed
again within the holding time. The laboratory suspects carryover from a previous sample on the apparatus. The laboratory
considers the TDS, Calculated result to be more accurate representation of the actual TDS for this sample.
Sample Preparation
All samples were prepared within method specified holding times. No preparation issues were noted.
Method Blanks
All blank values were within method acceptance criteria. No blank values exceeded the minimum reporting limit for any
analysis in this work order.
Laboratory Control Samples
All laboratory control samples were within method acceptance criteria, except as noted by qualifying flags. Batch BXE 1179
had low LCS recoveries for Chloromethane. It is important to note that certain flags on an individual analyte do not constitute
failure of the method as a whole. EPA methodologies recognize that it may not be possible for every compound to meet all
recovery or percent difference criteria. The batch passed required method criteria for these analytes.
Method Spikes
All method spike recoveries were within method acceptance criteria, except as noted by qualifying flags.
Method Spike Duplicates
All method spike duplicates were within method acceptance criteria, except as noted by qualifying flags.
Corrective Actions
There are no corrective actions associated with this work order.

A The Relative Percent Difference (RPO) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than
five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +I-the
RL is used to evaluate the DUP result.
* Indicates that a Quality Control parameter was not within specifications.
For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
