1.0 BACKGROUND
1.1 Site Information
The Seminole Mart No. 2 site is located at 691 Seminole Road in Broadway, North
Carolina (Figure 1). According to reports prepared by East Coast Environmental (ECE),
PA, underground storage tanks (USTs) were closed at the site in 2016. The UST closure
assessment encountered diesel fuel constituents that were detected with concentrations
above North Carolina Department of Environmental Quality (NCDEQ) action levels at the
site. Based on findings by the previous consultant, the site was classified by the NCDEQ
Division of Waste Management (DWM) UST Section as a “commercial high” risk site.

The following are some of the activities that have taken place at the site since
September 2016:

Ø One 10,000-gallon gasoline and one 4,000-gallon diesel fuel petroleum USTs
were permanently closed by removal in September 2016;
Ø Petroleum contamination was evident in the excavation for the diesel fuel UST
due to a hole in the tank and below the former product dispensers. Approximately
204 tons of contaminated soil from released diesel fuel were excavated and
removed from the site.
Ø A monitor well network (Table 1) was installed by ECE, PA, in January, March,
May, October, and December of 2017. The borings and well network wells were
used to assess the soil near the former UST system, delineate free product on
the groundwater table and delineate dissolved petroleum constituents in the
groundwater.
Ø Baseline groundwater monitoring events were performed by ECE, PA, in 2017
prior to implementing the remedial program. The baseline data indicated that
eleven of the existing monitor wells (MW-1, MW-2, MW-3, MW-4, MW-8, MW-11,
MW-12, MW-13, MW-14, MW-17 and MW-19) had a measurable thickness of
free product as diesel fuel. The initial maximum free product (diesel fuel)
thickness recorded in network wells in 2017 included: MW-1 - 2.85 ft., MW-2 –
1.76 ft., MW-3 – 3.0 ft., MW-4 – 1.90 ft., MW-8 – 2.48 ft., MW-11 – 5.41 ft., MW-
12 – 1.71 ft., MW-13 – 2.07 ft., MW-14 – 1.67 ft., MW-17 – 2.0 ft. and MW-19 –
1.64 ft.
Ø The NCDEQ issued Injection Permit WI0600195 for the remedial approach using
injection of surfactant solutions.
Ø Surfactant Injection (~19,165 gallons) was performed in April 30 – May 10, 2018.
Ø Aggressive fluid-vapor recovery (AFVR) was performed May 21-24, 2018, from
source wells impacted by petroleum, recovered 3,205 gallons of product,
surfactant/product emulsion, surfactant and petroleum-contaminated water.
Ø Total fluids recovery was performed between May 25, 2018 and October 26,
2021, using automated cycling of submersible pumps to recover free product,
surfactant with emulsified petroleum product and contaminated groundwater.
Ø Liquid level monitoring and well maintenance activities were performed by ECE,
PA, in June 2018, and gasoline was observed as free product in addition to
diesel fuel on the water table.
Ø The baseline data was used to calculate the quantity and concentration of the
surfactant solution that would be necessary to remediate the free product plume.
However, the actual maximum free product thickness was subsequently found to
Groundwater Monitoring Report CLES Project No. 17-051A
Seminole Mart No. 2, Broadway, NC March 13, 2023

be approximately double the amount that was identified during the baseline
assessment due to the presence of significant gasoline free product that was
located on top of the diesel free product. The gasoline free product was not
identified because it was initially located above the screened intervals of the
monitor wells. As the thickness of the diesel free product was reduced to below
the top of the screened interval, the gasoline free product was able to enter the
monitor wells. Therefore, injecting additional surfactant solution was necessary to
contact and remediate the additional gasoline free product plume that was
located at shallower depths than the diesel free product.
Ø Product thicknesses observed after the injection were a result of the surfactant
stripping product from source area soils, which included both diesel fuel and
gasoline products.
Ø Liquid level data following the initial injection and extraction event indicated that
now 13 of the existing monitor wells had a measurable thickness of free product
as diesel fuel and/or gasoline. The maximum free product thickness recorded in
network wells since the initial injection event included: MW-1 – 1.89 ft., MW-2 –
3.01 ft., MW-3 – 1.55 ft., MW-4 – 0.05 ft., MW-8 – 0.67 ft., MW-9 – 0.77 ft., MW-
10 – 4.54 ft., MW-11 – 4.43 ft. (gasoline), MW-12 – 0.23 ft., MW-14 – 0.33 ft.,
MW-15 – 1.82 ft., MW-16 – 1.34 ft., and MW-17 – 2.96 ft (red text used to identify
locations where free product was not previously observed). Well locations MW-
13 and MW-19 had no measurable thickness of free product as gasoline or diesel
fuel since the first injection/extraction event.
Ø Approximately 2,750 gallons of surfactant solution were injected September 6-7,
2019, approximately 2,750 gallons of surfactant were injected between October
31, and November 6, 2019, and approximately 2,900 gallons of surfactant were
injected into source area wells with evidence of product skim in the well screened
intervals in June 2021.
Ø Total fluids recovery has been performed on source area wells where free
product is persistent on the water table. Since May 2018, over 45,000 gallons of
liquids contaminated with petroleum have been recovered from the site.

This Groundwater Monitoring Report details the site activities that were performed
and observations made from July 2022 to March 2023.
Ø CLES performed well maintenance, free product recovery and liquid level
monitoring between July 2022 and March 2023. Product was removed either by
bailers or with pumps based on the liquid column height in the well. Since
October 2021, free product recovery has been performed manually to reduce the
volume of recovered groundwater that is not necessary to remove from the site.
Obsevations from the overall liquid level data indicate that the aerial extent of the
free product plume continues to decrease as no measurable thickness of free
product was observed in wells MW-2, MW-9, MW-4, MW-12, MW-8, MW-17,
MW-15, or MW-16 this sampling event.
Ø Measurements of product thicknesses were observed to rebound in wells MW-1,
MW-3, MW-10 and MW-12 between June 2022 and October 2022. Product
recovery slowed the rebound in MW-3, MW-10 and MW-12, however, the
thickness in MW-1 remains persistent due to a likely perched source of diesel
fuel that continues to seep to the water table intersected by MW-1. The product
thickness in MW-2 has been decreasing durin this time and the thickness in
MW-11 fluctuates at a thickness close to 0.6 feet.

Ø The magnitude of total volatile organic compound concentrations measured in
the monitor well network indicates a dcreasing trend likely due to the removal the
secondary petroleum contaminant source. Some low level rebound in benzene
concrentrations in wells MW-14 and MW-19 increase the aerial extent of the
benzene plume shown in Figure 6.The total thickness of free phase petroleum
(diesel fuel and gasoline) continue to be managed using total fluids removal from
source area wells by bailing and/or pumping that was performed during site
visits.
Ø Prior to sampling on February 15, 2023, groundwater level measurements were
attempted using an oil-water interface probe. The instrument probe
malfunctioned and measurements could not be collected on February 15. CLES
had repairs made to the interface probe and returned to the site March 8, 2023 to
measure liquid levels from the well network to document groundwater elevations
at the site and to estimate the groundwater flow direction and hydraulic gradient
on-site.
Ø Groundwater samples from 18 of the network monitor wells that intersect the
water table at the site were collected on February 15, 2023. Groundwater
samples were submitted for laboratory analysis for volatile organic compounds
(VOCs) by Method 624.1.

Figure 2, Site Map, presents the site features and monitor well locations.
1.2 Hydrogeological Description
1.2.1 Regional Geologic Setting
According to the North Carolina Geologic Survey, Geologic Map of North Carolina, 1985,
the site rests just east of the Fall Line, or boundary between the Piedmont Upland and
the Coastal Plain. Unconsolidated sediments with varying thicknesses rest non-
conformably over sedimentary deposits of the Middendorf formation. The Middendorf
formation consists of Cretaceous Age sand, sandstone and mudstone deposits.

Groundwater occurs in residual soils that were weathered from parent sedimentary rock.
Based on the surface topography depicted in the United States Geologic Survey (USGS)
National Map viewer of Topographic Maps, (Figure 1), the site rests at an elevation of
approximately 475 feet above mean sea level (ft-MSL). Topography on site slopes down
from Seminole Road to the north-northwest, and to the south-southwest. The surface
water features in the vicinity of the site are shown on Figure 1.
1.2.2 Site Hydrogeology
Monitor wells installed at the site, as well as published geologic information, were used
to describe site-specific hydrology. A summary of the monitor well construction of on-
site monitor wells is presented in Table 1. The monitor well locations are shown on
Figure 2. Groundwater levels measured March 8, 2023 in the monitor wells on site
indicate that groundwater is present at depths between 38.72 feet below the top of the
well casing (ft-btoc) in MW-1 and 45.39 ft-btoc in MW-16. The monitor well relative top-
of-casing elevations were previously reported by ECE, PA, as measured relative to an
assigned elevation of a site reference point. Historical groundwater level and elevation
data as reported by ECE, PA, and recent measurements by CLES are summarized in
Table 2. The groundwater potentiometric map, based on maps prepared by ECE, PA,
and measurements by CLES is presented on Figure 3.

1.2.3 Subsurface Lithology
According to ECE, PA, the subsurface residual soils were typically composed of fine-
grained clayey silt or silty clay, silt and sand to approximately 12 feet below the ground
surface (ft-bgs). The fine-grained soils rested over a zone of silty sand with rounded
pebbles in some locations from approximately 12 to over 20 feet in depth. Silt with sand
or silty sand from below the pebble zone rested over a white silty clay layer that was
encountered between 35 and 49 ft-bgs. Zones of medium and coarse sand were also
observed near and below the water table. The color of the soils varied from orange red
brown, yellow, white, brown, tan, orange or white with black. Bedrock was not
encountered to the termination depths of the borings.

2.0 SITE ACTIVITIES
2.1 Liquid Level Monitoring and Sampling
Liquid levels in the 21 network wells were measured on March 8, 2023, using an oil-
water interface probe. CLES’ personnel gauged liquid levels in general accordance with
the CLES Standard Operating Procedures (SOP). A copy of the CLES SOP is presented
in Appendix I. The measurement device was decontaminated between measurements.
A measurable thickness of gasoline/diesel fuel (>0.02 feet) as free product was present
in MW-1, MW-3, and MW-11. Well MW-10 had 0.01 feet of product. No measurable
thickness of petroleum product was observed in the remaining network wells that were
gauged.

CLES initiated purging activities to prepare for sampling. Either submersible pump with
a stainless-steel motor and impeller connected to polyethylene tubing that was
decontaminated before inserting it into each well, or an unused disposable bailer with
nylon cord, was used to purge the water column from the well before sampling. Purge
parameters including pH, conductivity and temperature were measured and the values
were recorded on field forms during well purging. Field parameters representative of the
aquifer before samples were collected on February 15, 2023, are summarized in Table
4. A summary of the data recorded on the field forms is presented in Appendix II.

Using the March 8, 2023, groundwater level data (summarized in Table 3), groundwater
elevations were calculated for network monitor wells that intersect the water table. The
potentiometric surface of the groundwater table was drawn using groundwater contours
of equal elevation that were estimated to predict the groundwater flow direction across
the site (Figure 3). Groundwater elevations on March 8, 2023, indicate that the site-
specific groundwater flow direction is generally to the east-northeast and the hydraulic
gradient, calculated using a three-point calculation from the water levels in MW-5, MW-
20, and MW-21, was estimated to be 5.8 x 10-3 feet/foot (ft/ft) to the east-northeast.
2.2 Groundwater Sampling and Analysis
On February 15, 2023, CLES collected groundwater samples from 18 of the network
monitor wells at the site. Samples were not collected from piezometers P-1 to P-6, or
wells MW-1, MW-2, MW-3, or MW-4 that had insufficient water to sample during this
event. Bailers with nylon cords and/or decontaminated sample pump with polyethylene
tubing were used to collect groundwater samples from the monitor wells in general
accordance with NCDEQ sampling guidance and CLES’ SOPs (Appendix I).

The groundwater samples were collected and analyzed to measure the dissolved VOC
concentrations in the site monitor wells after implementing supplemental surfactant
injection followed by total fluids extraction.

Groundwater samples were submitted to Eurofins Environment Testing Southeast, LLC
(formerly Environmental Conservation Laboratories, Inc.), for the following laboratory
analyses: VOCs by USEPA Method 624.1.
3.0 RESULTS
3.1 Elevation Measurements, Groundwater Flow, and Gradient
The depth to groundwater in the monitor wells measured from the top of casing ranged
from 38.72 feet below the top of the well casing (ft-btoc) in MW-1 and 45.39 ft-btoc in
MW-16 on March 8, 2023. Using the liquid levels measured this quarter and the relative
top of casing (toc) elevation data provided by ECE, PA, groundwater surface elevations
were calculated at each well location. Groundwater elevations across the site ranged
from a high elevation of 55.00 ft-rel elevation in MW-1 1 (corrected for the presence of
petroleum), to a low elevation of 48.50 ft-rel elevation in MW-21. Based on the
potentiometric surface of the water table presented on Figure 3, in general, the
groundwater flow appears to be to the east-northeast at a gradient of approximately
0.0058 ft/ft. The methods and calculations used to determine the hydraulic gradient and
groundwater flow direction are presented in Appendix II.
3.2 Groundwater Analytical Results
Groundwater samples from the network monitor wells at the site collected on February
15, 2023, were submitted for laboratory analysis. The table below provides a summary

Groundwater samples collected from 11 monitor wells contained benzene, each of which
had concentrations that exceed the benzene 2L Standard of 1 microgram per liter (μg/L).
MW-1, MW-2, MW-3 and MW-4 were not sampled due to insufficient water in the well.

Twelve of the groundwater samples analyzed contained ethylbenzene; however, none of
the reported concentrations exceeded the 2L Standard of 600 μg/L.

MTBE concentrations were reported in eight groundwater samples, two of the
groundwater samples contained MTBE at concentrations that were above the 2L
Standard of 20.

Fourteen groundwater samples contained naphthalene and 11 of these samples were
reported to contain naphthalene concentrations that were above the 2L Standard of 6
μg/L.

Ten groundwater samples contained toluene; however, none of the samples were
reported to be at concentrations that were above the 2L Standard of 600 μg/L.

Total xylenes were detected in 12 groundwater samples analyzed for VOCs, of which,
one sample was reported with total xylenes concentrations that were above the 2L
Standard of 500 µg/L.

Piezometers P-1 to P-6 do not intersect the groundwater table; thus, they were not
sampled. Wells MW-1, MW-2, MW-3 and MW-4 were not sampled this event.

Historical groundwater analytical data collected from 2017 to the current data set in July
2022 are compared to both the 2L Standards and the NCDEQ GCLs and are
summarized in Table 5. A copy of the laboratory report for the groundwater analyses
from samples collected February 15, 2023, is included in Appendix III. The locations of
monitor wells and the petroleum constituents detected in the groundwater samples
collected February 15, 2023, are presented in Figure 4. The pre-remedial benzene
isoconcentration contours and the former area of free product that were plotted using the
data reported November 1, 2017 (ECE, PA), are presented in Figure 5. Benzene
concentrations in the groundwater sampled on February 15, 2023, are shown in the
isoconcentration contour map presented in Figure 6.

Comparing the pre-remediation data reported November 1, 2017 (Figure 5), and the
post-remediation data from February 15, 2023 (Figure 6), shows the reduction of the
petroleum plume area since the innovative remedial activities were implemented. The
innovative remedial approach was initiated between April 30, 2018 and May 10, 2018
with supplemental injection events followed by extraction that were performed in
September 6-7, 2018, October 31 to November 6, 2019, and June 17-19, 2021. Based
on isoconcentration contours plotted from the 2017 pre-remedial data, the benzene
plume was in an oval area approximately 75 feet by 101 feet, and the measurable free
product was in a similarly oval area that was approximately 56 feet wide by 78 feet long.
Note: The maximum thickness of product in 2017 as diesel fuel was 5.41 feet at MW-
11. Based on the February 15, 2023 laboratory data, the extent of the benzene plume
where concentrations were reported above the 2L Standard was estimated to be in an
area that ranges from 10 to 23 feet wide and a length that is approximately 39 feet. The
area with measurable free product was in two intersecting oval areas, one that is
approximately 10 feet by 18 feet and the second that is approximately 20 feet wide and
up to 24 feet long. The new maximum product thickness measured March 8, 2023, was
3.62 (diesel fuel) feet in MW-1, central to the recovery area.

4.0 CONCLUSIONS
The activities conducted during the second half of 2022 and part od the first Quarter
2023 at the Seminole Mart No. 2 site included site maintenance, total fluids recovery,
and sampling the groundwater from the well network to assess the current site
conditions. Total fluids recovery was performed using, manual bailing, and/or manual
pump operation during site visits.

Groundwater monitoring was performed to evaluate the site for the presence of residual
free product and to document the extent of dissolved concentrations remaining in the
groundwater after the supplemental remedial actions were implemented.

Liquid levels were measured in the monitor well network on March 8, 2023. Based on
the potentiometric surface of the water table, the groundwater flow is generally to the
east-northeast at a hydraulic gradient of approximately 0.0058 ft/ft. A measurable
thickness of free product greater than 0.02 was present in three wells and one well had a
thickness of 0.01 feet. No other liquid level measurements detected free product in the
network monitor wells gauged or sampled in this event.

Groundwater samples were collected from 18 of the network monitor wells at the site
February 15, 2023. The benzene in eleven groundwater samples was measured at a
concentration that was above the 2L Standard in this event. In addition to benzene,
naphthalene,MTBE and total xylenes were reported at concentrations above their
respective 2L Standard in one or more wells.

Based on isoconcentration contours plotted using the February 15, 2023, laboratory
data, the benzene concentrations were above the 2L Standard in an area that ranges
from 10 to 23 feet wide and a length that is approximately 39 feet. The area with
measurable free product was in two intersecting oval areas, one that is approximately 10
feet by 18 feet and the second that is approximately 20 feet wide and up to 24 feet long.
The new maximum product thickness measured March 8, 2023, was 3.62 (diesel fuel)
feet in MW-1, central to the recovery area. The product plume is significantly reduced
from the free product area of 56 feet wide by 78 feet long that was observed in 2017.
The product thickness in well MW-1 had a thickness of 2.85 in 2017. The surfactant
injections has released fuel from the soil and the current thickness available for recovery
is 3.62 feet. The product thickness in MW-11 was 0.61 feet on March 8, 2023, which is
reduced from the greatest thickness of diesel fuel of 5.41 feet measured in MW-11 in
2017.
5.0 RECOMMENDATIONS
CLES recommends that the following actions be taken for timely and cost-effective
remediation to continue at the Seminole Mart No. 2 site:

• Continue the groundwater quality monitoring program in general accordance with
the approved revised semi-annual monitoring schedule.
• Perform an aggressive product removal event using AFVR or MMPE from wells
with residual free procuct. Following the aggressive product removal, continue
free product recovery until the no measurable thickness of product in the well
network on site is greater than 0.01 feet in the network wells.
Groundwater Monitoring Report CLES Project No. 17-051A
Seminole Mart No. 2, Broadway, NC March 13, 2023

• Use groundwater quality monitoring data to assess effectiveness of the corrective
measures and make necessary modifications to the recovery operations to
further attenuate the contaminant plume. After free product is not measurable in
the wells at the site, sample the network quarterly to facilitate closure of the
incident with NCDEQ.

Standard Operating Procedures

STANDARD OPERATING PROCEDURES

Soil Sampling, Soil Boring and Monitor Well Installation, Well Development

Soil borings are completed with a stainless steel hand auger, direct-push hydraulic drill or auger
rotary drill using either a macro core sampler, 3-1/4, 4-1/4, or 6-1/4-inch inside diameter
hollow stem augers. Soil borings are typically sampled at discrete intervals from the bucket
of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or
a split barrel sampler.

Monitor wells are completed in selected soil borings using one, two, or four-inch inside
diameter PVC casing and machine slotted screen intervals in accordance with North Carolina
guidelines. Clean quartz sand is typically used to fill the boring annulus around the well screen
to approximately one foot above the screened interval, approximately one foot of hydrated
bentonite is placed over the sand pack and neat cement grout or bentonite is placed above the
well seal. Concrete is placed to secure the wellhead in the top three feet of boring annulus.
Wellheads may be completed with either flush mounted traffic-bearing protectors with bolt
down covers or steel above-ground protectors set in a concrete pad. Temporary wells or
piezometers may be completed with the PVC riser cut at or above grade. The wellheads are
secured with locking caps.

Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or
peristaltic pump. When wells are developed by the driller, they may be developed with air
injection, water injection, pumping or bailing. Soil boring logs and well construction details
are typically prepared for presentation in a report appendix. Borings completed in bedrock
may be drilled using air rotary, coring, or sonic drilling methods.

Liquid Levels

Groundwater level measurements are typically obtained using an electronic sounding/interface
detection device which registers a tone or illuminated light when a probe makes contact with
the groundwater. Depth to groundwater measurements are obtained by lowering a probe
attached to a cable marked in 0.01 feet intervals into the well until the probe of the meter
intersects the product or water surface. The measurement from the top of the riser pipe or top
of casing (T.O.C.) to the liquid level is recorded. The measurement is recorded to the nearest
0.01 foot. The electronic interface probe is decontaminated between measurement locations.

LNAPL Measurements
Light Non-Aqueous Phase Liquid (LNAPL) present on the water table is measured using an
oil/water interface probe. The electronic meter has both an audible and illuminating light that
indicate when a liquid level is encountered. The oil/water interface probe registers a solid
tone/light when LNAPL petroleum product is encountered and a beeping tone/light when
groundwater is encountered. Depth to LNAPL measurements are obtained by lowering a probe
attached to a cable marked in 0.01 feet intervals into the well until the probe of the meter
intersects the product or groundwater. The measurements from the top of the riser pipe or top
of casing (T.O.C.) to the liquid level is recorded. The measurement is recorded to the nearest
0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL
measurement from the depth to groundwater measurement. The electronic interface probe is
decontaminated between measurement locations.

Soil Sampling

Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable.
Sampling procedures are followed to protect the chemical integrity of the soil samples and
minimize the potential for cross contamination. This includes discarding of the exterior of the
sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, collecting the
interior soil for screening with the PID or FID, and either pressure washing, steam cleaning,
or washing with non-phosphate detergent and/or rinsing sampling equipment with clean water
between sampling intervals. The samples are placed in glass jars, sealed, and placed in an ice
filled cooler. An aliquot of the sample is typically placed in a clean sealable bag and allowed
to reach ambient air temperature. The PID or FID is used to measure total organic vapors
(TOV) in the head space in each sample bag.

Excavation soil samples may also be collected from the bucket of excavation equipment. Care
to collect soil samples from excavation equipment includes retrieving native soil from material
that has not made contact with the excavating equipment. Samples are collected in sealable
bags or by directly filling sample containers using new gloves, laboratory provided sampling
utensils, or decontaminated stainless steel sampling equipment.

Field personnel don new, unused, disposable nitrile gloves at soil boring and sampling
locations. Gloves are changed between each sample interval. Sampling equipment such as
hand auger extensions and buckets, direct push samplers, split spoons and/or drilling augers,
are decontaminated before collecting samples.

Groundwater Sampling

Bailer or Dedicated Pump
Groundwater samples are collected using new dedicated polyethylene bailers or dedicated
pump with polyethylene tubing (or equal) at each monitor well. Before obtaining a sample, a
minimum of three well volumes of groundwater is typically evacuated from the well to
ensure collection of a sample representative of the in-situ groundwater conditions. Field
parameters (not limited to pH, specific conductance and temperature) are measured on
purged groundwater after each volume approximately equal to one water column in the well
is evacuated to monitor the changes of the field parameters in the groundwater as the monitor
wells are purged. Once the fluctuation of field parameters stabilizes to within ten percent
over three consecutive purge parameter measurements, or after the well is purged dry and
allowed to recover, the record sample is collected. The groundwater samples are collected by
directly filling laboratory-supplied containers with groundwater poured directly from the
dedicated disposable bailer or polyethylene tubing attached to the dedicated well pump.
Samples will be then transferred to insulated containers with ice for transport to the
laboratory. Field personnel don clean chemical resistant/non-reactive gloves at each well
during purging and don a new pair of gloves before filing sample containers.

Peristaltic Pump (Low Flow Method)
Groundwater is purged from the monitor wells using a peristaltic pump with either dedicated
Teflon-lined or PVC tubing inserted into the well, or using a clean section of disposable
silicon and a clean section of PVC tubing inserted into the well by the following low flow
sampling methods. The silicon tubing is inserted into the peristaltic pump. The silicon is
attached to the PVC or Teflon-lined tubing that is inserted into the monitor well to the bottom
of the well screen. The tubing is pulled back off of the bottom of the well with the end
located within the screened interval of the well and the peristaltic pump is started. The initial
flow from the well that passes through the peristaltic pump tubing is discharged into a bucket
or container. Once the initial turbid liquid effluent becomes relatively clear (lower turbidity)
the effluent may be passed through a flow cell for parameter measurements or captured in a
container so that a multi meter can be used to monitor field parameters. This minimizes
potential fowling of the flow cell and meters used to monitor field parameters. Field
parameters will be measured on groundwater purged from each well to monitor the changes
of the field parameters in the groundwater as the monitor wells will be purged. Field
parameters will be recorded after approximately each consecutive two minutes of pumping
from the peristaltic pump. Once the fluctuation of field parameters stabilizes at each well to
within ten percent over three consecutive measurements, the record sample is collected. If the
well is purged dry, it is allowed to recharge sufficiently for a sample to have be collected.
Samples will then be transferred directly from the section of silicon tubing into containers
supplied by the laboratory. Field personnel don clean chemical resitant/non-reactive gloves
at each well during purging and before sampling activities.

Decontamination Procedures

The potential for cross-contamination between sample locations is minimized by thoroughly
cleaning the sampling equipment, both prior to the initiation of sampling and between uses.
Glass and Teflon® sampling equipment, in-situ hydraulic conductivity measurement
equipment, bucket augers and split-spoon samplers used for soil sampling, and other tools and
equipment will be decontaminated between each use according to the following procedures:

• Remove excess soil/sludge as necessary.
• Wash and scrub the equipment with a phosphate-free detergent in a hot tap water (prior to
field use) or ambient tap water solution. Use a brush to remove particulate matter and
surface films. Repeat as necessary.
• Rinse thoroughly with tap water.
• Rinse thoroughly with analyte-free water (deionized water).
• Allow the equipment to air dry.
• Prevent inadvertent contamination during storage and transport.

All personnel engaged in equipment decontamination wear clean, disposable chemical
resistant non-reactive gloves.

Aquifer Testing Procedures

Aquifer hydraulic conductivity testing is performed at selected wells to evaluate the relative
hydraulic conductivity at targeted locations. Rising head slug tests will be performed at target
monitor well/piezometer locations. Prior to performing the tests, the monitor
wells/piezometers will be opened and allowed to equilibrate. The water level in each
well/piezometer is measured to the nearest 0.01 feet using a decontaminated water level probe.
This reading is used as the initial reading for the tests. Slug tests will be performed in the
monitor wells/piezometers by installing into the monitor well a pressure transducer equipped
with a data recorder or that is attached to a data recorder. After obtaining an initial water level
reading, a clean polyethylene bailer of known volume is submerged in the water in the
well/piezometer. The filled bailer is removed and the water level in the well/piezometer is
monitored with the pressure transducer as the water level in the well/piezometer returned to
static conditions. The volume of water removed by the bailer is noted. Tests may be repeated
on or more times in each test well/piezometer.

The transducer data is graphically evaluated in the field using Win-Situ (or equal) computer
software. The Win-Situ data is imported into an MS Excel® Workbook for analysis by
Bouwer-Rice techniques for partially or fully penetrating well screens using Aqtesolv®
computer software. The Bouwer-Rice techniques make a variety of simplifying assumptions
in the evaluation of slug test data. These include the assumptions that the aquifer in question
is homogenous, isotropic, and extends infinitely in the horizontal direction (Bouwer-Rice,
1976).

WHERE DISTANCE BETWEEN h1 AND h2 IS PARALLEL TO FLOW
DETERMINED FROM 3 POINT PROBLEM BY PROJECTION
i2 = MW-5-MW-21=49.14 -48.50 =0.0051
distance
Calculate Distance for point with Elevation = MW-20 between MW-5 and MW-21
MW-5 - MW-20 = 49.14 -48.91 =45.28
0.0051
Place point on line 45.28 feet from MW-5 toward MW-21, Draw line from point to MW-20
45.28 feet from MW-5.
Project MW-5 and MW-21 locations onto perpendicular line and measure new distance between projected well locations.
Gradient (a): divide change in head between MW-5 to MW-21 and divide by new distance to predict gradient.

Receipt
The samples were received on 2/15/2023 5:20 PM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.6°C
GC/MS VOA
Method 624.1_PREC: The surrogate recovery for the blank associated with analytical batch 752-1361 was outside the upper control limits.
Method 624.1_PREC: The LCSD was biased high in recovery for: Toluene-d8 (Surr). The LCS and LCSD recovered in a similar manner;
however, the LCSD was just outside of the acceptable range. All client samples had acceptable surrogate recoveries. (LCSD 752-1361/8)
Method 624.1_PREC: The surrogate recovery for the blank associated with analytical batch 752-1540 was outside the upper control limits.
Method 624.1_PREC: The following samples were prepped and loaded on the instrument within holding time, but due to the
instrumentation sequence the data were acquired after midnight. The data were reported.MW-16 (752-3131-12), MW-17 (752-3131-13),
MW-18 (752-3131-14), MW-19 (752-3131-15), MW-20 (752-3131-16) and MW-21 (752-3131-17)
Method 624.1_PREC: The following samples were diluted to bring the concentration of target analytes within the calibration range: MW-11
(752-3131-7), MW-17 (752-3131-13) and MW-20 (752-3131-16). Elevated reporting limits (RLs) are provided.
Method 624.1_PREC: Reanalysis of the following samples were performed outside of the analytical holding time due to over range target
compounds : MW-11 (752-3131-7), MW-17 (752-3131-13) and MW-20 (752-3131-16).
Method 624.1_PREC: Internal standard (ISTD) response for the following samples were outside of acceptance limits: MW-16
(752-3131-12), MW-17 (752-3131-13), MW-18 (752-3131-14), MW-20 (752-3131-16) and MW-21 (752-3131-17). The sample(s) was not
re-analyzed due to insufficient volume and/or the holding time had expired.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
