B. EXECUTIVE SUMMARY

1. Free Product: Free product was observed at this site in monitoring well MW-2 at a maximum thickness of 0.01’. Free product removal via hand baling and absorbent socks has apparently resulted in remediation. Free product was not present in MW-2 during the latest 2 sampling event conducted in 2023.

2. Contaminant Mass: Contaminant mass calculations cannot be completed at this
time since the vertical and horizontal extent of contamination has not yet been
defined.

3. Maximum Concentrations of Dissolved Groundwater Contaminants:

Current Groundwater Maximums:
Contaminant Result Well ID 2L Standard Benzene 1.2 ug/L (MW-1) 1 ug/L Toluene BDL (MW-1) 600 ug/L Ethylbenzene 3.5 ug/L (MW-1) 600 ug/L Xylenes 16 ug/L (MW-1) 500 ug/L 1,2,4-Trimethylbenzene 3.9 ug/L (MW-1) 400 ug/L 1,3,5-Trimethylbenzene 1.1 ug/L (MW-1) 400 ug/L Only benzene exceeded 2L Standards during the latest groundwater monitoring event for this site. No GCL violations were noted. 4. Extent of Dissolved Groundwater Contamination: The plume of dissolved groundwater contamination has been defined horizontally to 2L Standards. Vertical definition would require installation of a telescoping well at this site. Additional monitoring well(s) will be installed at this site during upcoming CSA activities after the UST at this facility is closed. 5. Maximum Soil Contaminant Concentrations (From IAA): Contaminant Result Sample ID Lowest MSCC TPH-GRO 194 mg/kg (P1-5) 50 mg/kg TPH-DRO 1,740 mg/kg (P2) 100 mg/kg Xylenes (total) 8.67 mg/kg (P1-5) 6.0 mg/kg sec-Butylbenzene 1.42 mg/kg (P1-5) 2.2 mg/kg n-Butylbenzene 3.04 mg/kg (P1-5) 2.4 mg/kg n-Propylbenzene 1.98 mg/kg (P1-5) 1.4 mg/kg Isopropylbenzene 0.76 mg/kg (P1-5) 1.3 mg/kg 1,2,4-Trimethylbenzene 11.4 mg/kg (P1-5) 6.6 mg/kg 1-Methylnaphthalene 0.531 mg/kg (P1-5) 0.054 mg/kg 2-Methylnaphthalene 0.692 mg/kg (P1-5) 1.5 mg/kg C5-C8 Aliphatics 110 mg/kg (P1-5) 68 mg/kg C9-C18 Aliphatics 914 mg/kg (P1-5) 540 mg/kg C9-C22 Aromatics 464 mg/kg (P1-5) 31 mg/kg
Based on the local potable wells, Lowest MSCC standards apply for this site. 6. Remedial Action Plan:
No CSA or CAP activities have been conducted for this site. The NCDEQ has approved for CSA activities to be delayed until after UST closure and new AST installation activities are completed at this release site. To date, free product activities including hand baling and introduction of oil absorbent socks into monitoring well MW-2 have resulted in apparent remediation of oil floating atop the shallow water table, which was noted in this well at a maximum thickness of 0.01’. It is suspected that the free product was a result of contaminant migration through the MW-2 borehole during installation.

7. Impacted Receptors:

(6) potable and (2) irrigation water supply wells are located within 1000’ of the
release source at this facility. No supply wells located within 250’ of the release
source. Supply well SW-1 (backup hospital water supply) and SW-6 (Buckberry
Falls community well) were sampled in conjunction with groundwater monitoring
activities and analyzed via Method 6200B last on July 11, 2023. Results for these
2 receptors was below laboratory detection limits for all petroleum related 6200B
constituents on that date.

1.0 Site History and Characterization

1.1 Introduction

MH Highlands-Cashiers Medical Center, LLP owns (1) 20,000 gallon diesel UST used
for a non-regulated boiler at the Highlands-Cashiers Medical Center facility located at
190 Hospital Drive in Highlands, North Carolina. Figure 1 illustrates the location of this
facility on the Highlands Quadrangle U.S.G.S. Topo Map. This facility contains multiple
permanent structures which are used for medical hospital operations. Figure 4 illustrates
the overall layout of this site and the UST location. Information regarding the UST in
use at this facility is contained in Table 1.

A release from the UST system was confirmed upon inventory reconciliation on
8/18/2022 which indicated an estimated loss of 3,400 gallons of fuel. Initial abatement
action activities have been conducted pursuant to the release confirmed by excavation of
product piping which revealed petroleum product beneath a cracked FRP elbow on the
generator return line. Municipal water supply is available to the medical center and some
properties within 1,500’ of the release source at this facility; however, most nearby
property owners are not connected to the municipal water supply and are served by
private wells. Figure 2 illustrates a receptor map, with well owner information
summarized on Table 5. Abatement activities conducted at the site were reported to the
NCDEQ in an Initial Abatement Action report dated November 16, 2022. A Phase II
LSA report was prepared and submitted to the NCDEQ for this site on December 13,
2022. 1.2 Scope of Services

Contained herein are the results of a groundwater sampling event as approved by the
NCDEQ. This Groundwater Monitoring Report contains documentation concerning the
following activities which have been conducted at this facility:

o Sampling of new and existing monitoring wells conducted by Henry Nemargut
Engineering on July 11, 2023.

o Laboratory analyses of groundwater samples conducted by Pace Analytical, Inc.
of Huntersville, NC.

2.0 Presentation of Current Site Assessment Information / Comparison to Historical Assessment Information 2.1 Historical Soil Assessment Information
The soils at the project site consist of silt, clay, sand & weathered rock of varying
proportions. Soil boring logs are contained on well construction records and boring logs
contains in the previously submitted IAA and LSA reports prepared for this site.

On August 29-30, 2022, Henry Nemargut Engineering and Ransier Environmental
Drilling mobilized drilling equipment to the site to conduct a free product check and
assess conditions of soil and groundwater in the vicinity of the UST system. On August
30, 2022, UST area monitoring well (B1/MW-1) was advanced to assess subsurface
conditions adjacent to the pea-gravel filled UST basin and piping source area soil
boring/monitoring well (P1/MW-2) was advanced at the piping leak location. Soil
samples were collected on August 30, 2022 during advancement of the borings B1/MW-1
and P1/MW-2 at 5’ to 10’ intervals to check for any vertical migration of release liquids
which could have migrated through the pea gravel filled basin. The UST area boring was
advanced to an approximate depth of 78’ below ground surface where competent bedrock
was encountered. A separate monitoring well was installed in the piping leak source area
to a depth of 65’ to assess for free product/groundwater impact (MW-2). Following
installation, groundwater was measured at an approximate depth of 52.02’ below top of
casing in MW-1 and at a depth of 47.62’ below top of casing in MW-2.

Additional soil borings were advanced along the product piping trench to assess for
horizontal migration of release liquids on August 31, 2022. One sample was obtained
from pea gravel where the product line enters the tank top STP sump since some liquids
accumulated in that sump. Figure 3/3A illustrate the locations of monitoring wells and
soil borings installed during site check activities. To confirm conditions of the UST site,
samples collected from in-situ soils during advancement of the monitoring wells and
piping trench borings were submitted to Pace Analytical, Inc. for analyses according to
EPA Methods TPH-GRO/DRO as recommended by the NCDEQ for diesel UST sites.
An additional sample was collected from the P1/MW-2 boring for risk-based analyses via
Methods 8260/8270/VPH/EPH as recommended for diesel release sites. All soil and
water samples collected were placed in laboratory supplied glassware, labeled with
sample location, analysis to be performed, time, date and sampler's name. The sample
jars were then immediately placed in a cooler, chilled with ice to approximately 4oC in
preparation of transportation to an analytical laboratory utilizing EPA approved chain-of-
custody procedures.

Results from TPH soil analyses indicate soils above NCDEQ Action Levels in the P1 and
P2 piping sample locations. No soil contaminants were detected above laboratory
detection limits in any other sample locations at the site. Results from the risk-based soil
sample collected from the P1/MW-2 boring were above the current Lowest MSCCs for
(8) compounds/compound groups. No compounds were detected exceeding Residential
of Commercial/Industrial Standards during the IAA investigation. Table 2/2A
summarize the laboratory results for the TPH/Risk-Based soil samples from 190 Hospital
Page - 3
Drive in Highlands, NC. Copies of the soil analytical report and the chain of custody
records for the TPH and risk-based soil samples collected at 190 Hospital Drive are
contained in the previously submitted IAA report.

2.2 Ground Water Flow Direction and Gradient

In order to estimate the groundwater flow direction in the vicinity of the petroleum
release, elevations of the monitor well casings were measured using surveying
equipment. During the July 11, 2023 sampling event, static water levels were obtained
from the monitor wells (see Table 3) and the data was used to compute a potentiometric
surface map. Figure 6 illustrates the current potentiometric surface map as calculated
based on the measurements obtained on July 11, 2023.

Groundwater data and monitoring well information were also used to estimate the
hydraulic gradient at the project site. Using the horizontal distance between the monitor
wells and the static water levels, the groundwater was calculated to flow toward the west
with a hydraulic gradient of approximately 0.0969 ft/ft.

2.3 Monitor Well Sampling and Analyses

On July 11, 2023, monitor wells MW-1 through MW-6 were sampled for analyses
utilizing Standard Method 6200B and MADEP VPH. Before collecting the samples, the
monitor wells were purged by removing a minimum of three well volumes to ensure that
the samples were representative of the actual groundwater conditions. The wells were
developed and sampled using a 12 volt submersible pump.

All samples were placed in laboratory supplied glassware, labeled with sample location,
analysis to be performed, time, date and sampler's name. The sample jars were then
immediately placed in a cooler, chilled with ice to approximately 4oC in preparation of
transportation to an analytical laboratory utilizing EPA approved chain-of-custody
procedures.

Laboratory analytical results indicate the presence of benzene above its current listed 2L
Standard in monitor well MW-1 at a concentration of 1.2 ug/l (2L Standard = 1.0 ug/l).
Total 6200B compounds were detected only in MW-1 at a concentration of 26.4 ug/l. No
other 6200B or VPH compounds were present in any other wells at the site. Table 4
summarizes the laboratory analytical results, and Appendix A contains a copy of the
laboratory analytical report and chain of custody records. Figure 7 contains a benzene
iso-concentration map, and Figure 8 contains a Total 6200B concentration map.
2.4 Supply Well Sampling and Analyses

No water supply wells were sampled during this sampling event.

2.5 Regional / Site Geology and Hydrogeology
The site is situated in the eastern Blue Ridge Belt. According to the Geological Map of
North Carolina local geology of the region is underlain with quartz diorite to granodiorite
Weathered bedrock was encountered at depths ranging from 5 to 40 feet below surface
during subsurface investigations at this site.

The partial Highlands Quadrangle U.S.G.S. Topographic Map included as Figure 1
indicates that the release site is located on a slight slope of a knoll at an approximate
elevation of 3967’ amsl. Surface waters in the vicinity of the release area generally drain
northwest towards the Big Creek located 510’ north at its closest distance to the piping
release source area. Big Creek feeds Lake Sequoyah which lies within the Cullasaja
River basin. 2.6 Plume Development

The monitoring well network at this release site was installed between August 30, 2022
and October 25, 2022. In the initial sampling events conducted at the site, 2L violations
for benzene, naphthalene, and all MADEP class compounds or the presence of floating
product were noted in monitor well MW-2. The MW-2 maximum free product thickness
was 0.01’. During the last 2 sampling events conducted on April 4, 2023 and July 11,
2023 no 2L violations were noted in MW-2. It is suspected that the free product was a
result of contaminant migration through the MW-2 borehole during installation which
how now been purged with continued development of this well during sampling events.

6200B compounds were present in MW-1 for the first time on April 4, 2023, and have
continued to increase in concentration during the July 11, 2023 sampling event. Benzene
is now present in MW-1 at a concentration above its 2L Standard, which suggests that
dissolved contaminants are migrating downgradient and 2L violations now extend
horizontally beyond the currently installed monitoring well network.

Since the vertical and horizontal extent of soil and groundwater contamination has not
been defined at this site, accurate comparisons cannot be made concerning the total
contaminant mass or seasonal fluctuations at this site at this time; however, dissolved
constituent concentrations are no longer present in piping release source area monitoring
well MW-2 but were present in downgradient well MW-1, suggesting that migration is
occurring.

3.0 Monitored Natural Attenuation

3.1 Natural Source Zone Depletion Status

Historically, 2L violations for 6 compounds/compound groups or free product have been
observed in MW-2 at this site. No free product or dissolved compounds were noted in
MW-2 during the latest monitoring event, which suggests that well development and oil
absorption efforts have been successful in free product remediation of MW-2.

4.0 Conclusions
4.1 General Summary
A Groundwater Monitoring event at Highlands-Cashiers Medical Center located at 190 Hospital Drive in Highlands, NC has been completed. From a review of all information gathered during this monitoring project, Henry Nemargut Engineering makes the following conclusions:

o During the latest sampling event conducted on the July 11, 2023, laboratory
analytical results indicate the presence of benzene above its current listed 2L
Standard in monitor well MW-1 at a concentration of 1.2 ug/l (2L Standard = 1.0
ug/l). No other 6200B or VPH compounds were present in any other wells at the
site.

o During the initial sampling events conducted at the site, 2L violations for
benzene, naphthalene, and all MADEP class compounds or the presence of
floating product were noted in monitor well MW-2. The MW-2 maximum free
product thickness was 0.01’. During the last 2 sampling events conducted on
April 4, 2023 and July 11, 2023 no 2L violations were noted in MW-2. It is
suspected that the free product was a result of contaminant migration through the
MW-2 borehole during installation which how now been purged with continued
development of this well during sampling events.

o 6200B compounds were present in MW-1 for the first time on April 4, 2023, and
have continued to increase in concentration during the July 11, 2023 sampling
event. Benzene is now present in MW-1 at a concentration above its 2L Standard,
which suggests that dissolved contaminants are migrating downgradient and 2L
violations now extend horizontally beyond the currently installed monitoring well
network.

o Since the vertical and horizontal extent of soil and groundwater contamination has
not been defined at this site, accurate comparisons cannot be made concerning the
total contaminant mass or seasonal fluctuations at this site at this time.

4.2 Recommendations
Based on information obtained during this sampling event, Henry Nemargut Engineering Services makes the following recommendations for this site:
o (2) additional shallow monitoring wells should be installed to define the
horizontal extent of 2L violations at this site in the approximate locations depicted
in Figure 8.
o Additional sampling should be conducted at this site to confirm contaminant
levels in monitoring and local supply wells on a quarterly basis until the UST at
this facility is properly closed and a comprehensive site assessment (CSA) can be
completed at this site.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
