SUBJECT: FINAL GROUNDWATER SAMPLING RESULTS
June 11 – 12, 2024 Sampling Event
Mayflower Mine VCP Site #C090
Wasatch County, Utah
Dear Dave:
This letter provides a summary of the methods and findings of the June 2024 groundwater
sampling event of BLX Mayflower LLC (BLXM) monitoring wells, groundwater piezometers, and
the Property Line Sump. Groundwater samples were collected from Monitoring Wells GW2,
GW4, Piezometers GW6, GW7c, GW8, and GW9a and the Property Line Sump.
Figure 1 identifies the BLXM project location and Figure 2 identifies the locations of each well
and piezometer.
This groundwater sampling event was performed to characterize groundwater quality in the area
of the Mayflower Waste Rock Repository and was voluntarily performed following discussions
with the Utah Division of Environmental Response and Remediation (DERR). BLXM is engaged in a
Voluntary Cleanup Program (VCP) of Site #C090, and although expanded from the water sampling
requirements outlined in the Remedial Action Plan (RAP) under the VCP, BLXM has
commissioned this work to further assess groundwater conditions at the site.
Starting in 2018 BLXM engaged in a groundwater quality monitoring program of monitoring wells
GW2 and GW4 pursuant to the RAP. To further assess groundwater conditions in the waste rock
repository, BLXM installed and sampled Piezometers GW6, GW7c, GW8, and GW9a in
accordance with an approved site water monitoring plan. Piezometers GW9a and GW7c are
replacement piezometers for wells damaged during site construction.

BACKGROUND INFORMATION

As part of site characterization activities, BLXM commissioned the installation of groundwater
monitoring wells in 2018. Monitoring Wells GW2 and GW4 are located east and southeast of the
Mayflower Waste Rock Pile and were sited to monitor water levels and water quality near the
down-gradient perimeter of the Waste Rock Pile.
In 2020 BLXM performed a subsurface investigation to determine the depth of the interface
between Waste Rock materials and underlying native soils. The exploratory borings were
constructed with 2-inch diameter PVC casing with discrete screened intervals for use as water
level piezometers to determine groundwater flow directions and to establish seasonal
groundwater level trends.
During the spring of 2023 BLXM replaced damaged piezometer GW9 with piezometer GW9a and
installed five additional piezometers near the west margin of the Waste Rock Pile. Figure 2
identifies the location of all wells and piezometers in the area and Figure 3 provides well
completion details for the sampled wells and piezometers.
The water levels of active piezometers and wells are measured regularly to identify water level
trends and determine the direction of groundwater flow, inferred from the groundwater
potentiometric surface. Figure 4 illustrates the potentiometric surface of the aquifer across the
site based on water level measurements recorded on July 1, 2024.
Groundwater Monitoring Well GW1 was abandoned during site construction and piezometers
GW3, GW5, GW7a, GW7b, and GW9 were abandoned during site construction or did not
encounter the saturated zone.
BLXM measures water levels in all active wells and piezometers monthly between December and
March and twice a month from April through June. Groundwater samples were collected from
monitoring wells GW2 and GW4 annually, in accordance with the RAP (2019) and Proposed Work
Plan for Site Characterization (2017). The June 11 and 12, 2024 sampling event described in this
report is the final RAP groundwater sampling event, completing the RAP scheduled monitoring
program.
Groundwater sampling was performed using the methodology outlined in the Remedial Proposed
Work Plan for Site Characterization, Proposed Phase 1 (Ski Village), dated November 16, 2017.
Additionally, the EPA document titled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures
(Puls, Robert W. and Barcelona, Michael J., 1996) was used for guidance. The sampling methods,
materials, field activities, and observations are described herein.
FIELD ACTIVITIES AND OBSERVATIONS

Field activities were conducted by Van F. King, PG on June 11 and 12, 2024 with the assistance of
a hydrogeologic technician, in accordance with the Remedial Action Plan (2019) and Proposed
Work Plan for Site Characterization (2017).

VCP #C090 Groundwater Monitoring June 2024

Groundwater Level Monitoring
Groundwater levels were measured using a Solinst® Model 102 electronic water level meter. The
depth to water was measured from the Top of the north side of the PVC well casing to the
nearest to 0.01 foot. These static water levels were the basis for determining groundwater purge
volumes and the potentiometric surface. Using surveyed casing elevations, groundwater
elevations were determined for the wells.
The pre pumping static water level of each well is summarized in Attachment A and the
potentiometric surface illustrated in Figure 4 is based on water levels measured on July 1, 2024.
The inferred direction of groundwater flow is towards the Property Line Sump as shown in Figure
4. Water level measurements made during pumping were recorded on Field Data sheets
(Attachment B) and purge volume calculations are summarized in Attachment A.

Groundwater Purging
Monitoring wells were purged and sampled between June 11 and 12, 2024, utilizing a Geotech®
Geosub submersible pump. The pump intake was lowered to the approximate center of the screened
intervals and pumping was controlled with a surface operated 300-Watt controller powered by a 12-volt battery.
The pump was attached to 3/8-inch inside diameter (1/2-inch outside diameter) polyethylene tubing dedicated
to each source.
A “low-flow” purging method was used for this sampling event. The low-flow method allows for
groundwater sampling without creating significant drawdown of the groundwater surface,
thereby minimizing turbidity, and allowing the collection of representative water samples. This
method requires continuous monitoring of water quality parameters and adjustment of the
pumping flow rate to minimize well turbidity and changes in water quality.
The calculated three-casing purge volumes for each of the wells are summarized in Attachment A, together
with the actual purge volumes removed prior to collection of water samples. Water quality parameters
stabilized during low flow pumping of each source, allowing the collection of water samples before 3 purge
volumes were removed.

Measurement of Water Quality Parameters and Sample Collection
An In-Situ Aqua Troll 500 multi-parameter water quality monitoring system was used to measure and
record water quality parameters while pumping. Water levels were measured manually with a Solinist
Model 102 Water Level Meter before, during, and after pumping. The Aqua Troll was programed to log
water quality parameters every minute for subsequent retrieval.
The measurement of water quality parameters and collection of groundwater samples were
conducted in accordance with EPA guidance document titled Low-Flow (Minimal Drawdown) Ground-
Water Sampling Procedures (Puls, Robert W. and Barcelona, Michael J., 1996) and the Proposed Work Plan
for Site Characterization (2017). The Aqua Troll water quality probes were configured in-line in a
flow-through cell, allowing groundwater to flow directly from each well into the cell before
discharge into a 5-gallon bucket.
Once pH, Specific Conductivity, Oxygen Reduction Potential, Turbidity, Dissolved Oxygen, and
water levels stabilized within specific ranges for at least three consecutive measurements,
VCP #C090 Groundwater Monitoring June 2024

Groundwater Monitoring Page 4 of 7 BLX Mayflower

groundwater samples were collected. The allowable specific ranges for each parameter from the
Proposed Work Plan for Site Characterization (2017) are shown on the headings of Field Data
reports in Attachment B.
Attachment C provides the monitoring results of each of the field-measured water quality
parameters recorded using the Aqua Troll system and Attachment B provides manually collected
data and water level measurements.
Once water quality parameters stabilized, the discharge tubing was disconnected from the in-
line field meters and groundwater samples were field-filtered with disposable Geotech® 0.45-
micron filters and placed in laboratory-preserved sample bottles. The samples were delivered
under Chain of Custody documentation to Chemtech Ford Laboratory in Sandy to be analyzed
for the following:
 Arsenic, Barium, Cadmium, Chromium, Copper, Iron, Lead, Mercury, Selenium, Silver,
and Zinc by EPA Laboratory Methods 6010D/3005A, 6020A/3010A, and 7470A.
 VOCs, SVOCs, and general water quality parameters for Wells GW2 and GW4.
All sampling equipment was decontaminated with biodegradable phosphate-free detergent and
rinsed by operating and circulating the pump with water prior to sampling and between wells.
Pump discharge tubing was dedicated to each well and samples were placed on ice and delivered
to Chemtech-Ford Laboratory in Sandy, Utah. One duplicate sample was submitted for
laboratory analysis and Chemtech included Level 3 Quality Assurance documentation with the
analytical reports.

GROUNDWATER MONITORING RESULTS

Groundwater analytical results are summarized in Tables 1, 2 and 3 together with the results of
previous analytical sampling of Monitoring Wells and piezometers. Tabulated field water quality
parameter data from the low-flow purging are presented in Attachment C and field data sheets
that include additional information collected during the low-flow purging are provided in
Attachment B. Laboratory analytical reports, chain of custody documentation, and the detailed
Level 3 Quality Control reporting is provided in Attachment D.

Water Quality
The laboratory analytical results of the June 2024 sampling of Monitoring Wells GW2 and GW4,
Piezometers GW6, GW7c, GW8, GW9a, and the Property Line Sump show a stable, improving
trend in water quality (refer to Tables 1, 2 and 3). In 2023 zinc and cadmium were detected in
piezometers GW8 and GW9a in concentrations above the screening levels, and in the recent June
2024 samples the concentrations were detected an order of magnitude less, further establishing
the trend of water quality improvement.
During the June 2024 groundwater sampling event all analytes were detected in concentrations
below their specific screening levels except for cadmium detected in a concentration of 0.0083
mg/L in groundwater collected from Piezometer GW8. For comparison, the cadmium screening
level is 0.005 mg/L (refer to Table 2). Piezometer GW8 is located in the interior of the Waste Rock
Pile, no contaminants were detected in concentrations of concern in down-gradient locations or
in the Property Line Sump.
VCP #C090 Groundwater Monitoring June 2024

Groundwater Monitoring Page 5 of 7 BLX Mayflower

Groundwater Monitoring Wells GW2 and GW4 located around the perimeter of the waste rock
pile have consistently shown non-detect or very low concentrations of zinc and cadmium through
the duration of the groundwater monitoring program that commenced in October 2018.
Furthermore, the iron concentration in Monitoring Well GW4 has shown a substantial decline
from a peak concentration of 50.2 mg/L in December 2019 to a non-detect reading during June
2024. No VOCs or SVOCs were detected in any of samples analyzed for these compounds. The
analysis of duplicate samples collected from Piezometer GW2 shows similar analytical results to
the standard sample, thereby validating sampling methods and laboratory analysis.
This is the final RAP scheduled groundwater sampling event. The DERR approved RAP outlined a
groundwater sampling schedule that included two sampling events per year for the first two years,
and annually for the next 3 years for a total of 5 years of data. The June 2024 groundwater
sampling event documents the end to the approved groundwater monitoring commitment.
The laboratory analytical results of groundwater samples collected between 2018 and 2024
show a stable, improving trend in water quality and demonstrate that the Extell Mayflower
Waste Rock Repository is not causing exceedances of groundwater standards in the aquifer
adjacent to the waste rock pile.

results of this groundwater sampling program.

Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
Flag Descriptions
J-LOW-C = Estimated low due to low recovery of CCV
J-LOW-L = Estimated low due to low recovery of LCS
MS-Low = Estimated low due to Matrix Spike recovery.
SPH = Sample submitted past method specified holding time.
