Corrective Measures Study
Former CSI Landfill Facility
Hudson, Caldwell County, North Carolina
NCD 086 871282
H&H Job No. CAL-005
1.0 Introduction
This Corrective Measures Study (CMS) has been prepared by Hart & Hickman, PC (H&H) on
behalf of Caldwell County to evaluate potential corrective actions for the former Caldwell
Systems, Inc. (CSI) facility and Caldwell County landfill (Site) located at 1200 Drag Strip Road
in Hudson, North Carolina. For the purposes of this and all future reports, the Site has the same
definition of "Site" in the Consent Agreement and Settlement between Caldwell County and the
North Carolina Department of Environmental Quality (NCDEQ; formerly NC Department of
Human Resources [NCDHR] and NC Department of Environment and Natural Resources
[NCDENR]) Division of Waste Management (DWM; formerly Division of Solid Waste
Management). The agreement was signed by the County on April 24, 1997 and by NCDENR on
August 26, 1997. The definition of the Site includes three different but contiguous tracts of land:
1) the tract which Caldwell County leased to CSI to operate a hazardous waste management
facility; 2) the County landfill property; and 3) the County property formerly known as the Haas
property. A Site location map is provided in Figure 1, and a Site layout is provided in Figure 2.
The former CSI facility operated as a hazardous waste management facility on a 1.59-acre parcel
leased from Caldwell County. The former CSI facility is located in the west -central portion of an
approximately 148-acre parcel of land owned by Caldwell County; approximately 103 acres of
this property was utilized as the Caldwell County landfill. The former Haas property occupies
approximately 44-acres directly west of the former CSI facility. The Site is bordered to the south
by residential properties on Drag Strip Road and Lick Mountain Drive, and to the east, north, and
west by undeveloped private property. The Site is currently regulated by NCDEQ DWM
Hazardous Waste Section (HWS) and has been assigned the facility ID number NCD086871282.
A brief summary of the Site is included in the following sections.

1.1 Site Background
The hazardous waste management facility was constructed by Caldwell County, which operated it
from April 1976 until January 1977. From March 1977 until 1989, Caldwell County leased the
facility to CSI. During this time, the facility incinerated and/or repackaged, consolidated, blended,
and liquefied waste for off -site shipment or use as fuel. The facility handled hazardous wastes
from the US Navy and other industries, including torpedo fuel, solvents, waste oils, paints, tank
bottoms, glues, and sludges.
In 1980, CSI submitted a Resource Conservation and Recovery Act (RCRA) Part A permit
application with the United States Environmental Protection Agency (USEPA) identifying itself
as a Hazardous Waste Management Facility; CSI was granted interim status for the facility. In
1982, CSI was directed by NCDHR Solid and Hazardous Waste Management Branch to submit a
RCRA Part B permit. The Part B permit application was submitted in August 1987. Before
NCDHR could act on the Part B application, Caldwell County attempted to evict CSI from the
property due to the County's concern that CSI was improperly operating the incinerator. Under a
court -approved settlement, CSI ceased incineration activities on May 31, 1988. After this date,
CSI continued to operate as an Interim Status Hazardous Waste Storage Facility, with operations
including fuel blending, waste bulking, and storage of hazardous wastes.
On September 13, 1989, a fire broke out at the incinerator site. Following an investigation, the
Caldwell County Health Director issued an order of abatement requiring CSI to cease all
operations at the Site unless CSI could show the facility could be operated without threatening
public health and welfare. CSI and Caldwell County entered into a court -approved settlement
whereby CSI agreed to cease operations by December 1, 1989 and to close the facility as required
by RCRA regulations.
1.2 Regulatory History
CSI ceased operations by the required deadline and submitted a closure plan to NCDENR.
NCDENR approved the closure plan on July 13, 1990 and directed both CSI and Caldwell County
to implement the closure plan. On April 17, 1990, USEPA issued a RCRA 3008(h) Administrative

Order (AO) to CSI as operator of the facility and Caldwell County as the facility owner requiring
CSI and Caldwell County perform Interim Corrective Measures, a RCRA Facility Investigation
(RFI), a CMS, and a Corrective Measures Implementation (CMI) to complete the corrective
measures.
Caldwell County entered into three separate agreements or decrees regarding environmental
impacts at the Site. As part of these agreements, Caldwell County agreed to investigate and
remediate groundwater impacts, while CSI and the potentially responsible parties (PRPs) that
brought waste to CSI for disposal (Generator Settling Defendants) agreed to complete demolition
of the facility structures and address soil impacts on the 1.59-acre parcel leased from Caldwell
County. It is important to note that the only soil impacts requiring cleanup were on the
1.59-acre parcel where CSI operated. The parcels east of the CSI parcel include the two inactive
landfill cells which have been properly closed/capped. The former Haas parcel west of the CSI
parcel is undeveloped land owned by the County with no documented chemical usage or disposal.
These agreements and decrees include:
- the Settlement Agreement between Caldwell County and the Generator Settling
Defendants, entered in May 1997;
- the Consent Agreement and Settlement entered with NCDENR on August 26, 1997 in
the Office of Administrative Hearings, 90 HER 0823; and
- a Consent Decree entered January 16, 1998, in United States v. Caldwell County, et
al., United States District Court for the Western District of North Carolina, Statesville
Division, Civil Action No. 5:97 CV 125-V
The CSI facility demolition and impacted soil removal and capping activities were completed and
are summarized in the Removal Action Summary Report (CRA 2001) and the Summary of
Removal Action and Corrective Measures Study (CRA 2005). As referenced in the latter report,
a risk assessment conducted for the Site indicated no unacceptable risks to human health in relation
to the former facility and Site soils and recommended no further corrective action for Site soil.

1.3 Summary of Site Assessments
Numerous, extensive investigations of potential impacts at the Site have been conducted since
1987. Because there were multiple parties involved including CSI, PRPs that took wastes for
incineration, Caldwell County, USEPA Region IV, NCDENR Hazardous Waste Section and
NCDENR Solid Waste Section, after each phase of assessment the stakeholders "Group" met to
discuss results and to agree upon necessary future work. A full summary of investigations prior
to Caldwell County entering into the three agreements described in Section 1.2 is given in the
1998 RFI Workplan (ARCADIS 1998). A Phase I REI was submitted in 1999 (ARCADIS 1999a),
and Phase II RFI Parts A and C (ARCADIS 1999b, 2001) were subsequently prepared. As
described in greater detail below, the Phase II RFI Part B was proposed but not implemented due
to off -Site access issues. Since 2001, groundwater monitoring at the Site has been conducted
annually. A brief summary of these investigations is given below. Because soil has already been
addressed and Caldwell County is responsible only for groundwater impacts, only groundwater,
surface water, and well/spring assessment results are discussed.
In September 1987, USEPA, HWS, and Waste Management Division, RCRA Branch initiated a
case development that included sampling groundwater springs on the Truitt Haas property.
Organic compounds were detected in the Haas Spring. Subsequent sampling of the spring by
USEPA contractors in 1988 and 1990 confirmed the presence of organic compounds. Monitoring
wells installed in 1990 and 1991 confirmed groundwater impacts at the Site, with the highest
concentrations detected in wells located immediately southeast of the former CSI facility.
Caldwell County contracted Geraghty & Miller to conduct a preliminary groundwater
characterization in October 1992. The results of that investigation indicated that groundwater
flows eastward and westward from the ridge that housed the former CSI facility, with impacts
detected in the Haas Spring and in two monitoring wells located between the former CSI facility
and the landfill. A global groundwater monitoring network was subsequently installed and first
sampled in January 1995. Monitoring wells GM-1, GM-2, MW-2, and MW-3 were sampled for
the complete Appendix IX parameter list, which includes volatile organic compounds (VOCs),
semi -volatile organic compounds (SVOCs), chlorinated and organophosphorus pesticides,

SMARTER ENVIRONMENTAL SOLUTIONS

herbicides, and metals. Only some VOCs, SVOCs, and arsenic were detected at concentrations
above North Carolina Administrative Code (NCAC) 2L Groundwater Standards (2L Standards).
Based on the results of these initial sampling events, the Phase I RFI groundwater sampling plan
was modified to VOCs in all wells sampled and SVOCs (Base Neutrals only), arsenic, manganese,
and chlorinated pesticides (alpha-BHC, beta-BHC, and heptachlor) in select wells.
The results of the Phase I RFI indicated that VOCs, predominantly chlorinated VOCs (CVOCs),
were the primary constituents of concern (COCs) at the Site. The highest concentration of VOCs
was detected in wells in and immediately downgradient to the east of the former CSI facility (i.e.,
towards the Site landfill away from residential areas). A review of groundwater geochemical
parameters indicated that conditions were favorable for the natural attenuation of Site COCs.
Elevated metals concentrations in groundwater were determined to be the result of naturally
occurring background conditions. This was discussed and agreed upon by the "Group" and though
not formally documented, sampling for metals was dropped from future sampling events and was
not requested by the regulatory agencies beyond the Phase I RFI. 1,4-Dioxane was detected in
two of six monitoring wells (GM-1 and DW-1). No chlorinated pesticides were detected.
In addition to groundwater, seven surface water samples and eight potable water well or domestic
spring samples were collected as part of the Phase I RFI. The surface water samples were analyzed
for VOCs, while the well/spring samples were analyzed for VOCs, SVOCs (Base Neutrals only),
arsenic, manganese, chlorinated pesticides, and ammonia. Three surface water samples contained
low levels of VOCs. VOCs were also detected in three springs (Kevin Tolbert Spring, Ray Austin
Spring, and former Haas Spring). Phase II RFI sampling was then conducted to confirm impacts
in the nearby springs and evaluate the lateral and vertical extent of impacted groundwater.
During Phase II Parts A and C RFI sampling (ARCADIS 1999b, 2001), VOCs were not detected
in the Kevin Tolbert or Ray Austin springs; however, they were detected in the former Haas Spring.
Subsequent drive point sampling collected from the streambed downstream of the Haas Spring
indicated no impacts above laboratory reporting limits.

SMARTER ENVIRONMENTAL SOLUTIONS

To delineate groundwater impacts, four shallow and four deep monitoring wells were proposed to
be installed on off -Site properties as part of the Phase II Part B RFI. Caldwell County was able to
purchase a portion of an adjacent property from the Hutton Family Trust. Installation of a shallow
and deep monitoring well on the former Hutton property was attempted. However, a borehole was
advanced approximately 50 feet into bedrock and no groundwater was encountered. NCDENR
was contacted and it was agreed that the borehole be abandoned and additional wells not be
attempted until additional properties could be purchased. However, despite multiple efforts, the
County was unable to purchase additional properties that were hydraulically downgradient of the
Site. Therefore, in agreement with NCDENR, the County instituted an annual groundwater
monitoring program. Groundwater monitoring events, including analysis of VOCs and natural
attenuation indicator parameters, have been conducted on an annual basis since 2001.
In order to protect human health and the environment, a Declaration of Perpetual Land Use
Restrictions was recorded in the Caldwell County Registry (Deed Book 1524, Page 338) on
October 12, 2004. In this Declaration, Caldwell County agreed to the following perpetual land use
restrictions (LURs) for the Site:
1. Any use of groundwater located at or under the property is prohibited, including for
drinking, bathing, irrigation, watering livestock, or for any other purpose which would
cause groundwater to come into contact, either directly or indirectly, with people.
2. No water supply well may be installed or maintained on the property. The drilling of
new water supply wells is prohibited, and all existing water supply wells must be
abandoned in compliance with applicable regulations.
3. The property is restricted to industrial use only.
4. The owner shall submit a notarized letter annually confirming the Declaration is still
recorded in the Office of the Caldwell County Register of Deeds and that activities and
conditions at the property remain in compliance with the LURs.
As described in the most recent certification letter dated June 21, 2023, the Declaration is still
recorded with the Caldwell County Register of Deeds and all LURs have been maintained. With
NCDEQ's knowledge and consent, two wells/springs on the property have not been abandoned so

they can be used for monitoring purposes only. However, all associated pumps and piping have
been removed, and the wells are capped and locked.
1.4 Objectives
The objective of this revised CMS is to evaluate potential corrective measures for remediation of
groundwater impacts at the Site and address items included in a letter dated November 28, 2022
from NCDEQ. A CMS (Revision 2) was finalized by H&H on behalf of Caldwell County on
March 18, 2018. Although a 45-day public participation period began on August 3, 2018 and a
public hearing was conducted on September 5, 2018, the CMS was never finalized. Therefore,
NCDEQ requested an update to the CMS in the letter dated November 28, 2022. As part of the
update, NCDEQ also requested sampling of Site monitoring wells for per- and polyfluorinated
alkyl substances (PFAS) and completion of an updated receptor survey.
To achieve the above referenced objectives, this revised report will:
- Review and update the site conceptual model, including Site topography, geology and
hydrogeology, receptor survey, and potential contaminants of concern in groundwater;
- Establish remedial objectives for groundwater;
- Identify and develop corrective measures alternatives for the site;
- Evaluate corrective measures alternatives, including short- and long-term
effectiveness, reduction in wastes, implementability, community and state acceptance,
and cost estimates;
- Recommend and justify the proposed corrective measures; and
- Specify the monitoring and reporting schedule.

2.0 Site Conceptual Model
A site conceptual model was developed as part of the RCRA Facility Investigation (RFI) Workplan
that was submitted to NCDENR on March 12, 1998. The site conceptual model in the RFI Workplan
was reviewed and updated using information gathered during completion of the RFI, subsequent
annual monitoring, and recent updated receptor survey and sampling for PFAS. The updated site
conceptual model is presented below.
2.1 Site Geology and Hydrogeology
2.1.1 Site Topography
The Site is located within the Piedmont physiographic and Inner Piedmont tectonic province
(NCGS 1985). The topography of the Site is characterized by gently rolling to undulating hills
with moderate slope valleys. The surrounding area is relatively mountainous, maturely dissected
terrain with local relief ranging from 300 to 600 feet. Topographic elevation at the site varies from
approximately 1,700 feet above mean sea level (ft msl) at the ridge where the former CSI facility
is located to approximately 1,440 ft msl in the valley near the toe of the landfill (Figure 3). Surface
water at the Site drains away from the ridge where the former CSI facility is located to the east and
the west. Intermittent streams are present in east- and west -trending valleys on both sides of the
ridge.
2.1.2 Site Geology
As described in the RFI Workplan, bedrock in the region consists of mica schist, with muscovite,
biotite, mica, and sillimanite common along with varying amounts of garnet and pyrite. Beds of
quartzite, amphibolite gneiss and schist lenses, and garnetiferous schist may also be locally present.
The schist weathers to a yellow to dark red clay, depending on the amount of biotite present in the
rock. There are no reported faults at the Site, though the Site is in a seismic impact zone.
Subsurface investigations at the Site indicate soils are comprised of the Cecil-Pacolet-Rion
Association, which are characterized by gently sloping to steep, well -drained soils that have a clayey
N.

or loamy subsoil. These soils are formed in residuum from igneous and metamorphic rocks.
Unconsolidated soils at the Site consist of micaceous silts and sands. Based on air -hammer cuttings,
bedrock at the Site appears to be a gneissic schist. Bedrock depth varies depending on the topography,
with depths to bedrock ranging from 38 feet below ground surface (ft bgs) at GM-3 to 50 ft bgs at
GM-1.
As part of the RFI Workplan, a lineament analysis was conducted based on aerial photographs of
the area immediately surrounding the former CSI facility. The lineament analysis indicated that
the most predominant lineament trend is N 600-700 W, and the second -most prevalent lineament
trend is N 600-70' E. These lineament orientations can be interpreted as being representative of
the most prominent local fault or fracture orientations in the area and as such would be expected
to influence groundwater migration through the crystalline portion of the bedrock aquifer.
2.1.3 Site Hydro _geology
Groundwater beneath the Site occurs in an unconfined aquifer that includes the unconsolidated
materials and the interconnected network of faults, fractures, and metamorphic foliations that
permeate the underlying bedrock. Recharge to the aquifer is primarily through precipitation. In
some areas of the site, groundwater is present in the unconsolidated materials above the bedrock
surface, while in other locations the uppermost water bearing unit occurs in shallow bedrock. The
depth -to -groundwater across the Site is generally greatest in the area of the ridge where the former
CSI facility is located (approximately 75 ft below top of casing [bTOC] at FPC-MW-03 and MW-
A), and least in the downgradient portions of the Site (approximately 10 ft bTOC at MW-2). The
depth and availability of groundwater in the deeper bedrock wells is variable and dependent on the
bedrock aquifer characteristics at the well location (Table 1).
Vertical groundwater gradients measured between well pair MW-2 and MW-2A (near the northern
edge of the Site property) indicate a consistent upward gradient, with an average gradient of 0.050
ft/ft from 2013 to 2022 (Table 2). Conversely, the vertical gradients between well pair MW-3 and
MW-3A (near the eastern edge of the Site property) indicate a consistent downward gradient, with
an average gradient of 0.141 ft/ft from 2013 to 2022. As described in the RFI Workplan

SMARTER ENVIRONMENTAL SOLUTIONS

(ARCADIS 1998), additional historic well pairs GM-2/MW-B2 (near the former CSI facility) and
FPC-MW-07/FPC-MW-07A (near the eastern edge of the Site property) consistently had
downward gradients. MW-B2 has since been abandoned, and FPC-MW-07 has not been located
since 2009.
The ridge upon which the former CSI facility sits acts as a natural groundwater divide, with
groundwater flowing to the east and west away from the ridge (Figure 4). During the most recent
2022 groundwater monitoring event, the horizontal groundwater gradient in the unconsolidated
aquifer was approximately 0.056 ft/ft, as measured between monitoring wells FPC-MW-02 and
MW-3. Slug tests conducted in February 1995 indicated an average hydraulic conductivity of
2.2E-04 centimeters per second (cm/s), or 228 feet per day (ft/d), in the unconsolidated zone
(ARCADIS 1998). Based on lithologic information obtained at the Site, an effective porosity of
0.2 can be assumed. Thus, the estimated groundwater flow rate in the unconsolidated aquifer is
approximately 65 feet per year (ft/yr).
Cross -sections illustrating the topography, generalized lithology, hydrogeology, well construction
information and the most recent VOC groundwater quality data (October 2022) are provided as
Figure 5 and Figure 6. The cross-section transect location map is included as Figure 7.
2.2 Receptor Survey Update — 2023
An updated receptor survey was conducted as part of this revised CMS. The results of the receptor
survey are summarized in the following sections.
2.2.1 Potable Water Supplies
A survey for potable water supplies was performed for the area within a 1-mile radius from the
center of the source area. Figure 8 depicts the 1-mile radius from the source area. Table 3 details
the private wells and springs located within the 1-mile radius. A windshield survey was completed
on January 12, 2023 to confirm previously identified wells in October 2017 and identify additional
wells or springs not previously located. To the extent practicable, the owners of the wells and
springs were contacted to determine the status of the wells and springs and to inquire if the property

SMARTER ENVIRONMENTAL SOLUTIONS

owners were connected to municipal water. Caldwell County was also contacted to provide
municipal water account information for those properties where wells or springs were observed to
evaluate the presence of wells potentially used for drinking water.
As indicated on Table 3 and Figure 8, most properties with wells are reportedly connected to
municipal water. Based on the updated receptor survey, the closest identified water supply well
used for drinking water is located approximately 1,700 ft to the southwest and generally cross -
gradient of the former CSI facility. Other than this supply well, no water supply wells used for
drinking water were identified within 0.5 mile of the landfill boundary or former CSI facility.
Properties with springs that are not connected to municipal water are generally
undeveloped/forested land.
Table 4 provides historical analytical data for samples collected from the previously identified
wells and springs. Samples were collected from eight springs and wells for analysis of VOCs as
part of Phase I RFI sampling in October 1998. Five locations (Alan Tolbert Spring, Leonard
Tolbert Spring, Martha McLean Well, Ray Austin Well, and Truett Haas Well) did not contain
VOCs at concentrations above laboratory reporting limits. Detections of VOCs in the remaining
three locations are summarized below:
• The former Haas Spring contained 1,4-dioxane and tetrachloroethene (PCE) at
concentrations above 2L Standards in October 1998. This spring was disconnected and
left in -place on the Site property for monitoring purposes. 1,4-Dioxane was detected at
concentrations above the 2L Standard through at least March 1999, then analyses for this
constituent were discontinued. PCE was detected at concentrations above the 2L Standards
through November 2003, but has not been detected during annual monitoring events since
2004.
• The Kevin Tolbert Spring contained methylene chloride and PCE at concentrations above
2L Standards in October 1998, but resampling in March 1999 indicated no detections. Note
that methylene chloride is a common laboratory contaminant. This spring was
disconnected and left in -place for monitoring purposes, but has not been sampled since
1999.

• The Ray Austin Spring contained methylene chloride at concentrations above 2L Standards
in October 1998, but resampling in March 1999 indicated no detections. As noted above,
methylene chloride is a common laboratory contaminant. This spring was previously used
for irrigation and livestock purposes, but the property is connected to the public water
service.
Note that water supply wells or springs have not been sampled for analysis of PFAS. The potential
for PFAS impacts to water supply wells or springs are discussed further in Section 4.6.
2.2.2 Surface Water
A number of connected intermittent streams are present on the Site property. Intermittent streams
in the eastern portion of the Site (where most Site COCs have been detected in groundwater) are
unnamed tributaries to Pilot Branch, and intermittent streams in the western portion of the Site are
tributaries to Brushy Fork. Both Pilot Branch and Brushy Fork are characterized as Class C by
NCDEQ.
As part of the Phase I RE (ARCADIS 1999a), seven surface water samples were collected for
analysis of VOCs from intermittent streams located both on- and off -Site (Figure 9). The results
of the surface water sampling event are summarized in Table 5. The results at that time were
compared with the USEPA Region III Biological Technical Assistance Group surface water
screening levels for fauna and no exceedances were found. When compared to current surface
water standards, vinyl chloride concentrations exceeded the NCAC 213 Surface Water Standard
(213 Standard). However, since the date of the surface water sampling in 1998, concentrations of
vinyl chloride in groundwater have reduced to below the 2B Standard; as such, it is considered
unlikely that vinyl chloride remains in surface water at concentrations above the 213 Standard.
SW-5 was collected on -Site downgradient of the northern inactive landfill cell. No VOCs were
detected during Phase I RFI sampling in SW-7, which is located downstream of SW-5.
As part of the Phase II Part C RFI (ARCADIS 2001), four seep samples were collected along two
stream beds located near the northern, northeastern, and eastern boundary of the landfill (Figure

9). The seep samples were analyzed for Appendix IX VOCs and none were detected at these
locations as shown on Table 5 of this CMS. However, when the seep sampling was completed in
2001 as part of the Phase II Part C RFI, the laboratory detection limit for vinyl chloride was 5 µg/l
which is above the 2B Surface Water Standard.
In 1991 and 1992, biological assessments were conducted by USEPA contractors at the Site to
evaluate impacts to terrestrial and aquatic ecosystems from potential releases from the landfill and
former CSI facility. The results of the 1991 biological assessment indicated: no evidence of
terrestrial impacts; no toxicity to aquatic organism or algae; all habitats surveyed were capable of
supporting aquatic ecosystems; and impacts to the structure and function of streams draining the
landfill compared to the background station. The 1991 biological assessment concluded that
streams north and south of the landfill have been impacted, but potential downstream impacts were
not determined.
The results of the 1992 biological assessment indicated: no evidence of terrestrial impacts;
sub -lethal effects (reduction in offspring) at one sample station adjacent to the landfill; all sample
stations were capable of supporting aquatic ecosystems; severely impaired aquatic communities at
two sample stations closest to the landfill; moderately impaired aquatic communities at two sample
stations on the north side of the landfill; and slightly impaired aquatic communities at the
remaining sampling stations. The 1992 biological assessment concluded that the greatest impacts
to Site streams were localized to areas immediately adjacent to the landfill. Downstream locations
were only slightly impacted and recovery in the biological condition is evident. In addition, the
non -point sources of cattle and horse pastures were identified as potential sources other than the
landfill. No additional biological assessment of the stream was deemed necessary/required by
NCDEQ or USEPA.
Note that surface water samples have not been collected for analysis of PFAS. The potential for
PFAS impacts to surface water is discussed further in Section 4.6. Also note that the biological
assessments by USEPA referenced above, which resulted in no additional assessment
requirements, are considered pertinent for evaluation of impacts associated with PFAS as well as
VOCs.

2.2.3 Environmentally Sensitive Areas
The Site property and adjacent properties were evaluated for the existence of environmentally
sensitive areas (ESAs). The following agencies were contacted to determine the possible existence
of ESAs: US Army Corps of Engineers; NC Division of Coastal Management; NC Natural
Heritage Program; US Fish & Wildlife; US Forest Service; National Park Service; NC Department
of Natural and Cultural Resources; NC Forest Service; State Parks Service; NC Division of Water
Resources (DWR); and the NC Wildlife Resources Commission. Responses were received from
all agencies except the US Army Corps of Engineers, National Park Service, and State Parks
Service. These agencies were contacted multiple times without response. If a significant response
is received, they will be forwarded to NCDEQ. A copy of the responses from each of the
responding agencies is included in Appendix A.
The NC DWR noted that the Site is in the Catawba River Basin. The western edge of the property
drains to Brushy Fork while the remaining portions of the property drain to Pilot Branch. Brushy
Fork and Pilot Branch ultimately drain to Lake Hickory (Class WS-IV, B, and CA). However, the
location where Pilot Branch drains to Lake Hickory is located downstream of the water supply
intake that is the source for the Class WS-IV listing. Brushy Fork drains to Gunpowder Creek,
which is listed on the EPA -approved NC 2022 303(d)/305(b) Integrated Report as Impaired for a
fair benthic macroinvertebrate community rating. Therefore, both Brushy Fork and Gunpowder
Creek are currently considered to be in ESAs for the protection and maintenance of aquatic life.
No other ESAs were found to exist on the Site property or adjacent properties.
2.3 Potential Contaminants of Concern
2.3.1 Chlorinated Volatile Organic Compounds
As described in Section 1.3, VOCs are the primary COCs at the Site based on historical assessment
data. A summary of historical VOC data is provided in Table 6. Figure 10 depicts the VOCs
detected in each well during the most recent sampling event in October 2022.
The following VOCs were detected above 2L Standards during the most recent groundwater
monitoring event completed in October 2022: benzene, 1,4-dichlorobenzene (1,4-DCB),
14
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Caldwell County - CAL/CAL.005 - CMS 14

SMARTER ENVIRONMENTAL SOLUTIONS

1,2-dichloroethane (1,2-DCA), and vinyl chloride. Other VOCs, including PCE, 1,1,2-
trichloroethane, 1,1-dichloroethane (1,1-DCA), 1,2-dichloroethane (1,2-DCA), 1,2-dichloropropane
(1,2-DCP), and naphthalene, have exceeded 2L Standards in the previous five years, but were not
detected above 2L Standards during the most recent sampling event. Appendix B contains graphs
showing concentration versus time for VOCs that have historically exceeded 2L Standards at Site
monitoring wells.
VOC concentrations are generally highest in monitoring well GM-1, which is located in the source
area of the former CSI facility. During the most recent sampling event in October 2022, GM-1
contained the highest concentrations of benzene (5.6 micrograms per liter [µg/L]) and 1,2-DCA (47.2
µg/L), which were the only two VOCs detected above 2L Standards in October 2022 in monitoring
well GM-1. Although several other VOCs were detected in October 2022, concentrations were below
respective 2L Standards. 1,4-Dioxane was detected in this well in 1998 at 570 µg/L but has not been
analyzed for since that time. Therefore, the current concentration or historic trend of this constituent
is not available. Total VOC concentrations of analyzed constituents have decreased substantially over
time in this well, from a maximum of 2,509 µg/L in August 1996 to 91.3 µg/L in October 2022
(i.e., 96% reduction).
Monitoring wells FPC-MW-03 and MW-C are located west of the former CSI facility. Similar to
GM-1, these wells have experienced substantial reduction in total VOC concentrations over time.
Total VOC concentrations decreased to non -detect in FPC-MW-03 from October 2007 (443 µg/L) to
October 2022 (100% reduction). No VOCs have been detected above laboratory reporting limits at
FPC-MW-03 during the last two monitoring events completed in 2021 and 2022. No VOCs have
been detected above laboratory reporting limits in monitoring well MW-C since October 2012.
On the southern side of the former CSI facility, total VOC concentrations have also declined
substantially. In monitoring well FPC-MW-01, located immediately southeast of the former facility,
total VOC concentrations decreased more than 99% between February 2003 (211 µg/L) and October
2022 (1.3 µg/L). VOCs have not been detected above 2L Standards in this well since October 2015.
In addition, no VOCs have been detected above laboratory reporting limits in monitoring well GM-
6, located approximately 400 ft north of the former facility, since October 2009.

SMARTER ENVIRONMENTAL SOLUTIONS

Monitoring wells MW-2 and MW-2A are located near the northern Site property boundary,
approximately 1,500 ft northeast of the former CSI facility. Total VOC concentrations in MW-2 have
declined 98% from January 1995 (142 µg/L) to October 2022 (2.6 µg/L). In October 2022, no VOCs
were detected above 2L Standards. During the last 10 years, benzene is the only VOC to
intermittently exceed the 2L Standard (1 µg/L) in MW-2. Total VOC concentrations in MW-2A have
declined 85% from November 2003 (231 µg/L) to October 2022 (33.7 µg/L). At monitoring well
MW-2A, 1,4-DCB (11.9 µg/L) and vinyl chloride (1.2 µg/L) were detected at concentrations slightly
above 2L Standards in October 2022.
Monitoring wells FPC-MW-07 and FPC-MW-07A are located near the northeastern Site property
boundary, approximately 2,500 ft northeast of the former CSI facility. Monitoring well FPC-MW-07
has not been located since the October 2009 sampling event. However, total VOC concentrations had
already declined nearly 99% from July 1995 (1,539 µg/L) to October 2009 (17.4 µg/L). In
October 2009, only benzene (2.42 µg/L) and 1,4-DCB (8.4 µg/L) were detected slightly exceeding
2L Standards. Total VOC concentrations in FPC-MW-07A have declined more than 99% from
October 2009 (1,333 µg/L) to October 2022 (12.5 µg/L). In October 2022, only benzene (L1 µg/L)
was detected slightly exceeding 2L Standards in FPC-MW-07A.
Monitoring wells MW-3, MW-3A, and GM-5 are located near the eastern Site property boundary,
approximately 2,600 ft east-northeast of the former CSI facility. Total VOC concentrations have
decreased to non -detect in monitoring well MW-3 from January 1995 (16,527 µg/L) to October 2022.
Similarly, total VOC concentrations decreased to non -detect in monitoring well MW-3A from
November 2003 (1,106 µg/L) to October 2022. Total VOC concentrations have decreased 96% in
monitoring well GM-5 from July 1995 (290 µg/L) to October 2022 (9.5 µg/L). No VOCs were
detected above 2L Standards in these three wells October 2022. Additionally, no VOCs have ever
been detected in MW-3A exceeding 2L Standards.
Concentrations of total VOCs have declined in most Site wells by greater than 95% since their
respective maximum concentrations. In addition, VOCs were detected above 2L Standards in only

three of eleven monitoring wells during the October 2022 sampling event. In most instances, the
exceedances were only slightly above 2L Standards.
As referenced in Section 1.3, Caldwell County purchased a portion of the east adjacent property
from the Hutton Family Trust and installation of a shallow and deep monitoring well on this
property was attempted. A borehole was advanced approximately 50 feet into bedrock and no
groundwater was encountered. The County was unable to purchase additional properties that were
hydraulically downgradient of the Site in order to complete additional assessment activities.
However, as referenced above, concentrations of VOCs have reduced over time and only minimal
exceedances of 2L Standards have been detected in the most downgradient monitoring wells
during recent monitoring events.
2.3.2 Per- and Polyfluorinated Alkyl Substances
As requested by NCDEQ in a letter dated November 28, 2022, PFAS samples were initially
collected from a subset of monitoring wells in January 2023. After discussion of initial results
with NCDEQ, an additional sampling event was completed in April 2023. The methodology and
results of the PFAS sampling are discussed below. A summary of PFAS groundwater data is
provided in Table 7 and depicted on Figure 11.
The groundwater sampling activities were conducted utilizing low-flow/low-stress sampling
methods in accordance with USEPA Laboratory Services and Applied Science Division (LSASD)
protocols using a peristaltic pump and high -density polyethylene (HDPE) tubing, where feasible.
However, due to the depth to water in several monitoring wells, a PVC bailer and/or stainless -steel
submersible pump were used to collect groundwater samples utilizing the multi -volume purge
method outlined in the LSASD. A PVC bailer was used for sampling of monitoring wells MW-
3A, FPC-MW-01, FPC-MW-03, FPC-MW-07A, GM-1, GM-6, and MW-C, and a submersible
pump was used for sampling of deep well DW-1. During sampling, groundwater parameters of
pH, temperature, specific conductivity, oxidation-reduction potential (ORP), and turbidity were
recorded in approximate 5-minute intervals (or per calculated casing volume for wells sampled
using the multi -volume purge method) until groundwater parameters stabilized or the well went
dry. Following stabilization, groundwater samples were collected from the sample tubing directly

into laboratory -provided containers. The USEPA's "Clean Hands, Dirty Hands" sampling method
was also utilized during the groundwater sampling activities. Samples were delivered under chain -
of -custody protocol to Eurofins for analysis of PFAS by modified USEPA Method 537.1. The
analyte list and reporting limits for the analyses were provided to NCDEQ for approval via email
prior to sampling.
Quality Assurance/Quality Control (QA/QC) samples were collected to assess the field sampling
and analytical programs. The QA/QC samples consisted of the collection of duplicates, field
blanks, and equipment rinse blanks. Blanks were collected using laboratory -provided PFAS-free
water. A duplicate sample and field blank were collected during each sampling event (January
and April 2023). One equipment rinseate blank was collected from the water level meter during
the January 2023 sampling event, and two equipment rinseate blanks were collected from the water
level meter and submersible pump during the April 2023 sampling event. The duplicates, field
blanks, and equipment rinseate blanks were submitted to the laboratory for analysis of PFAS by
modified USEPA Method 537. 1.
PFAS are an emerging contaminant and significant uncertainty exists regarding potential remedial
goals. Therefore, laboratory analytical results for the groundwater samples were compared to
multiple screening levels, including the USEPA's Interim and Final Health Advisory Levels
(HALs) dated June 2022, USEPA Tapwater Regional Screening Levels (RSLs) dated May 2023,
USEPA Proposed Maximum Contaminant Levels (MCLs) dated March 2023, and NCDEQ
Interim Maximum Allowable Concentrations (IMACs) dated April 2022, where applicable. Note
that NCDEQ has not established specific 2L Standards for PFAS compounds to date. A summary
of the laboratory analytical results for the groundwater samples is provided in Table 7 and the
laboratory analytical report is provided in Appendix C.
Laboratory analytical results indicate that several PFAS compounds were detected in the
groundwater samples collected from the Site. However, this report primarily focuses on PFAS
compounds detected at concentrations above established screening levels for data comparison
purposes, which include the following: perfluorooctane sulfonic acid (PFOS), perfluorooctanoic

acid (PFOA), perfluorobutanesulfonic acid (PFBS), perfluorononanoic acid (PFNA), and
perfluorohexanesulfonic acid (PFHxS).
PFOS
PFOS was detected above the USEPA Interim HAL of 0.02 nanograms per liter (ng/L) in
monitoring wells FPC-MW-05, FPC-MW-07A, MW-2, MW-3, MW-3A, and GM-6. However,
the Interim HAL is considered less pertinent than the other USEPA screening levels since other
screening levels were released more recently. PFOS was detected at concentrations above the
USEPA Proposed MCL of 4 ng/L in monitoring wells MW-3, MW-3A, and GM-6. The PFOS
concentration in GM-6 also exceeded the USEPA Tapwater RSL of 40 ng/L. Concentrations of
PFOS ranged from 1.7 ng/L (FPC-MW-05) to 60 ng/L (GM-6).
PFOA
PFOA was detected above the USEPA Interim HAL of 0.004 ng/L and the USEPA Proposed MCL
of 4 ng/L in monitoring wells FPC-MW-01, FPC-MW-07A, MW-2, MW-2A, MW-3, MW-3A,
GM-4, GM-5, GM-6, and DW-1. Concentrations were also above the USEPA Interim HAL in
monitoring well FPC-MW-05; however, as referenced above, the Interim HAL is considered less
pertinent than the other USEPA screening levels since other screening levels were released more
recently. The PFOA concentration in monitoring well MW-3 also exceeded the USEPA Tapwater
RSL of 60 ng/L. However, the NC IMAC of 2,000 ng/L was not exceeded in any of the monitoring
wells sampled at the Site. Concentrations of PFOA ranged from 1.7 ng/L (FPC-MW-05) to 140
ng/L (MW-3).
PFBS, PFNA, and PFHxS
Although PFBS, PFNA, and PFHxS were detected in Site monitoring wells at concentrations
ranging from 2.1 to 48 ng/L, concentrations were less than respective USEPA Final Health
Advisory Levels (PFBS only) and/or USEPA Tapwater RSLs (PFBS, PFNA, and PFHxS). With
regard to the USEPA Proposed MCL, the hazard index was calculated for the combined
concentrations of PFHxS, PFNA, and PFBS per USEPA guidance (note that GenX chemicals were
not included in the laboratory analyses, as discussed with NCDEQ). The calculated hazard index
exceeded the USEPA Proposed MCL of 1.0 in monitoring well MW-3, as indicated on Table 7.
Calculated hazard indices were less than 1.0 for all remaining Site monitoring wells.

QA/QC Sample Results
The QA/QC sample results for the equipment rinse blanks and field blanks indicated no detections
of HAS compounds above the practical quantitation limit (PQL) with the exception of a detection
of PFOS in the equipment rinse blank (Equipment Blank 3) collected on April 13, 2023 from the
stainless -steel submersible pump prior to use at deep well DW-1. The PFOS concentration
detected in the equipment rinse blank was 2.3 ng/L; however, PFOS was not detected in well DW-
I. The submersible pump was not used for sampling of any other monitoring wells. Based on
review of the data, the detection of PFOS reported in the equipment rinse blank does not appear to
significantly impact the data usability or the conclusions presented in this report.
Based on results of the 2023 HAS groundwater sampling, PFAS are considered as a potential
COC for the Site and are discussed in the following sections.

3.0 Corrective Measures Study Clean-up Objectives
The goal of this revised CMS is to evaluate potential corrective actions to protect human health
and the environment by mitigating the release of contaminants to the surrounding groundwater and
surface water. As described in Section 1.2, CSI and the Generator Settling Defendants were
responsible for demolishing the former CSI facility and remediating soil impacts. Since the facility
has been demolished and soil impacts have been removed (CRA 2001, 2005), the only impacts
that remain are those in Site groundwater.
Historical sampling events over the last 25 years have indicated that VOCs are the primary COCs
in groundwater at the Site. Groundwater VOC impacts at the Site can generally be described as
forming a relatively large, dilute plume with a significantly decreasing contaminant concentration
trend. In North Carolina, groundwater impacts are generally compared to the 2L Standards, and
2L Standards are readily available for VOCs for comparison. However, North Carolina also has
established criteria for risk -based environmental remediation under North Carolina General
Statutes (G.S.) 130A 310.68 through 310.77. Under the risk -based option, site -specific
remediation standards may be developed in lieu of 2L Standards. In order to protect human health
and the environment, the clean-up objectives for VOCs in Site groundwater shall be the State of
North Carolina 2L Groundwater Quality Standards or, as applicable, site -specific remediation
standards developed under NCGS 130A 310.68 through 310.77. Alternatives for site -specific
remediation standards are discussed further in Section 4.0.
As requested by NCDEQ, PFAS were recently evaluated as a potential COC in groundwater at the
Site due to historical operations. The results of the sampling indicated PFAS at varying
concentrations across the Site. However, evaluation of the data is challenging because PFAS are
an emerging contaminant and significant uncertainty exists regarding remedial goals. NCDEQ
has not established specific 2L Standards for PFAS compounds to date, and many of the screening
levels established by USEPA are in draft form. Based on discussions with NCDEQ personnel, this
CMS proposes a monitoring -only approach for PFAS. If future data suggest an alternate approach
is warranted, a CMS Addendum will be submitted specifying cleanup objectives and proposed
corrective measures.

4.0 Identification and Development of Corrective Measures Alternatives
4.1 Identification of Corrective Measures
This section identifies corrective measures alternatives to be evaluated relative to the cleanup
criteria noted in Section 3.0. The following alternatives will be evaluated:
- No action;
- Institutional controls (i.e., LURs);
- Active treatment and/or remediation; and
- Monitored natural attenuation (MNA) via long-term monitoring.
The following sections describe the corrective measures alternatives and associated evaluation in
greater detail.
4.2 Evaluation Criteria
Consistent with the requirements of this CMS and RCRA guidance documents, the corrective
measures alternatives will be evaluated using the following criteria:
- Protection of human health and the environment;
- Compliance with applicable federal, state, and local regulations;
- Control of the source of release;
- Short-term effectiveness in minimizing impact on the environment and local
community;
- Long-term effectiveness and permanence;
- Reduction of toxicity, mobility, and volume;
- Implementability;
- Cost; and
- Community acceptance.
Historical environmental assessment indicated that the primary source of contamination was the
former CSI facility. Per the Consent Decree, CSI and the PRPs were responsible for demolishing

the facility, removing impacted soil, and capping the site. Demolition, excavation, and capping
activities are summarized in the Removal Action Summary Report (CRA 2001) and the Summary
of Removal Action and Corrective Measures Study (CRA 2005). Because the known source was
removed and/or controlled through demolition of Site structures and soil excavation, followed by
capping, fencing, and recording of LURs, the source of contamination is considered adequately
controlled. Evaluation of the other criteria referenced above are included in the discussion of
corrective action alternatives in the following sections.
4.3 No Action
Under the no action alternative, there would be no further monitoring or remedial activities at the
Site, and Caldwell County would apply for a No Further Action (NFA) letter from NCDEQ. The
no action alternative was considered by virtue of the engineering and institutional controls
currently in place. These include restricted Site access, perimeter security, and existing LURs.
However, reliance on engineering and institutional controls under NCDEQ regulations requires
entry of the site into the risk -based remediation program under NCGS 130A 310.68 through
310.77, which is covered under the institutional controls option in Section 4.4. NCDEQ
regulations would not allow no action without entering the risk -based remediation program.
Therefore, the no action alternative will not be evaluated further in this CMS.
4.4 Institutional Controls
Under the institutional controls alternative, exposure to Site groundwater would be prevented
through perpetual LURs or other land -use controls. This would require entry of the Site into the
risk -based remediation program under NCGS 130A 310.68 through 310.77. The Site already has
LURs prohibiting the use of Site groundwater and zoning the Site for industrial use only. This
alternative would entail additional assessment to evaluate whether the extent of impacted
groundwater extends beyond the boundaries of the Site. If groundwater impacts were found on
off -Site parcels above cleanup objectives, this alternative would entail implementation of LURs
or other land -use controls on those properties. For properties not already owned by the county,
this would involve either purchasing additional parcels from downgradient property owners to add
23
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Caldwell County - CAL/CAL.005 - CMS 14
Update/Updated CMS/Final to DEQ/Caldwell County Updated CMS_20230630.docx hart h i c k m a n
SMARTER ENVIRONMENTAL SOLUTIONS

to the Site or having the downgradient property owners agree to LURs or other groundwater use
controls on their property.
In 2000, Caldwell County was unsuccessful in multiple attempts to purchase additional
downgradient parcels to delineate the extent of groundwater impacts, and it is uncertain whether
additional attempts to purchase parcels would succeed. Similarly, it is uncertain whether
downgradient property owners would agree to LURs or other controls prohibiting the use of
groundwater.
Due to concerns regarding implementability, the institutional controls remedy will not be evaluated
further in this CMS. However, Caldwell County may elect to pursue risk -based remediation
alternatives at a later date, if future monitoring data suggest that risk -based closure may be a viable
option. In that event, the Site would be entered into the risk -based remediation program under
NCGS 130A 310.68 through 310.77, and a CMS Addendum (or Risk -Based Remedial Action
Plan) would be submitted detailing the proposed risk -based remediation alternatives.
4.5 Active Treatment and/or Remediation
At the time of the prior CMS submittal, enhanced reductive dechlorination (ERD) was considered
as a remedial option. However, based on the latest monitoring data, some of the VOC constituents
remaining at concentrations above 2L Standards are hydrocarbon constituents that are not amenable
to remediation via ERD (benzene and 1,4-dichlorobenzene). Other technologies are available that
can treat both CVOCs and hydrocarbon constituents, such as in -situ chemical oxidation. However,
monitoring data collected since the date of the last CMS confirm that VOC concentrations are
reducing over time due to natural attenuation; therefore, the additional cost associated with active
remediation to address VOCs is not considered warranted. In addition, the use of active treatment
and/or remediation technologies for PFAS is considered problematic since PFAS are an emerging
contaminant and significant uncertainties exist regarding remedial options and associated
effectiveness. According to the Interstate Technology Regulatory Council (ITRC; 2022), treatment
technologies for PFAS are continuing to evolve and "it is prudent to use caution in implementing
long-term remedies". The most successful technologies implemented to -date have been
sequestration technologies that bind or immobilize PFAS; however, bioremediation, chemical

oxidation, chemical reduction, and thermal technologies are currently being evaluated by the
scientific community. Due to the uncertainty of remedial alternatives, unknown equipment and
substrate requirements, and evolving clean-up objectives for PFAS, as well as monitoring data
confirming natural attenuation of VOCs, active treatment and/or remediation was not evaluated
further within this CMS.
4.6 Monitored Natural Attenuation via Long -Term Monitoring
MNA via long-term monitoring is a remedial option in which groundwater samples are routinely
collected from select monitoring wells for analysis of compounds present in Site groundwater.
These data are used to evaluate compound concentrations over time and to evaluate whether natural
processes such as reductive dechlorination continue to occur at the Site. Additionally, MNA data
are used to understand plume migration over time to ensure that any potential receptors will not
be impacted, thereby protecting human health and the environment.
The extensive database of VOC groundwater monitoring data generated since 1999 provides solid
evidence that natural attenuation of the VOC contaminant plume is occurring at the Site. In order
to evaluate trends in total VOC concentrations, a Mann -Kendall analysis was conducted using the
groundwater monitoring data collected from the Site monitoring wells since 2001. Mann -Kendall
is a non -parametric statistical analysis used to evaluate trends over time. H&H utilized an
Excel -based Mann -Kendall tool developed by GSI Environmental, Inc. The results of the
Mann -Kendall analysis are included in Appendix D. Of the 12 wells analyzed, eight wells were
identified as decreasing, two wells were identified as probably decreasing, and two wells (MW-
3A and GM-6) were identified as having no trend. Guidance for the Mann -Kendall Toolkit
indicates a "no trend" result can be considered as evidence that the plume concentrations are not
increasing at the sampling point, similar to a "stable" result. In addition, as discussed in Section
2.3, total VOC concentrations have declined in most wells by greater than 95% from their
respective maximum concentrations. The significant decreases in VOC concentrations are
illustrated by the VOCs concentration versus time trend graphs presented in Appendix B.
Therefore, both the Mann -Kendall analysis and the trend graphs provide strong evidence that

SMARTER ENVIRONMENTAL SOLUTIONS

MNA is occurring within the diffuse VOC groundwater plume and support MNA as the selected
remedy for VOC impacts within groundwater the Site.
As PFAS are an emerging COC, research in the scientific community is on -going to evaluate the
potential transformations of PFAS and overall contaminant plume attenuation with time within
natural groundwater systems. As one PFAS groundwater monitoring event has been completed at
the Site, insufficient data are available to determine if stabilization of the PFAS contaminant plume
and/or transformation of individual PFAS compounds are occurring at the Site; therefore,
continued monitoring is needed to evaluate PFAS concentration trends. Based on discussions with
NCDEQ personnel, this CMS proposes a monitoring -only approach for PFAS. If future data
suggest an alternate approach is warranted, a CMS Addendum will be submitted specifying
cleanup objectives and proposed corrective measures.
A natural attenuation corrective action approach is most appropriate where impacted soils are not
continuing to be a source of groundwater impacts, chemicals of concern are biodegrading, and
potential receptors are not affected. As previously referenced, soil impacts have been removed
(CRA 2001, 2005), and the only impacts that remain are those in Site groundwater. Groundwater
monitoring data confirm that VOCs are biodegrading, and future monitoring data will provide
additional information regarding PFAS degradation and/or plume stabilization.
With regard to potential receptors, water supply wells and springs in the area were previously
sampled for VOCs and no impacts were identified in active drinking water wells in the site vicinity
(see discussion in Section 2.2.1). Samples have not been collected from water supply wells for
analysis of PFAS. The closest water supply well used for drinking water is located approximately
1,700 ft to the southwest and generally cross -gradient of the former CSI facility. Other than this
supply well, no water supply wells used for drinking water were identified within 0.5 mi of the
landfill boundary or CSI facility. Based on distance and gradient, impacts to water supply wells
used for drinking water are unlikely. However, sampling of water supply wells would be needed
for confirmation. Evaluation of water supply well sampling data for PFAS would be challenging
due to uncertain cleanup objectives and alternate sources in the area, such as septic systems.

With regard to surface water, surface water samples were previously sampled for VOCs (see
discussion in Section 2.2.2). Vinyl chloride was detected in one sample at a concentration slightly
above the 2B Standard in 1998, but concentrations are likely reduced to below the 2B Standard at
present based on groundwater monitoring data indicating reductions in vinyl chloride
concentrations in groundwater. Samples have not been collected from surface water bodies for
analysis of PFAS. However, evaluation of surface water sampling data for PFAS would be
challenging due to uncertain cleanup objectives. In addition, the nearest surface water bodies are
classified as Class C, which indicates that they are not sources of public water supply. Based on
the SWAP website, the nearest downstream public water supply intake is located approximately
20 miles to the southeast. This intake is located along the Catawba River and receives discharge
from multiple upgradient tributaries. Based on distance and discharge criteria, this public water
supply intake is unlikely to be affected by the release at the Site. Biological assessments of surface
water bodies were performed historically by USEPA and, based on the results, no additional
biological assessment of the stream was deemed necessary/required by NCDEQ or USEPA.
Implementation of the MNA alternative would be relatively simple, as Caldwell County currently
conducts a long-term monitoring program. The overall costs would be much lower compared to
an active remediation alternative. In order to monitor the groundwater plume for up to 30 years,
costs are estimated to be in the range of $300,000 to $500,000. Because MNA is demonstrated to
already be occurring at the Site for VOCs and annual long-term monitoring has been completed
for over a decade at this Site, this alternative is expected to be accepted by the community.

5.0 Corrective Measure Recommendations
As discussed in Section 4.0, MNA via long-term monitoring was selected as the preferred
corrective action for the Site. Monitoring will continue until contaminant concentrations have
been reduced to below 2L Standards; or until No Further Action can be achieved using NCDEQ-
accepted risk -based remedial goals. MNA with long-term monitoring is a cost-effective, easy -to -
implement alternative that should receive community acceptance.
To verify the selected remedy is protective of human health and the environment, groundwater
concentrations will be monitored over time. The annual VOC monitoring program that has been
conducted at the Site since 2001 included FPC-MW-01, FPC-MW-03, FPC-MW-07, FPC-MW-07A,
MW-2, MW-2A, MW-3, MW-3A, MW-C, GM-1, GM-5, GM-6, and the former Haas Spring. As
described in Section 2.3, the results of annual monitoring indicate that VOC concentrations have
declined substantially in Site monitoring wells. Indeed, many monitoring wells in the network have
not contained VOCs above 2L Standards for at least five years. This includes monitoring wells FPC-
MW-01 (no exceedances since 2015), MW-3 (no exceedances since 2016), MW-3A (no exceedances
since 2003), NM-C (no exceedances since 2009), GM-6 (no exceedances since monitoring began),
and the former Haas Spring (no exceedances since 2003). As such, these sampling locations are not
included in the proposed monitoring plan, as outlined in Table 8. Additionally, as monitoring well
FPC-MW-07 has not been located since 2009, this well is proposed for removal from future
groundwater monitoring events.
Table 8 presents a summary of the proposed groundwater monitoring plan. Based on the volume of
VOC monitoring data collected at the site over the past 25 years, H&H proposes to reduce the
sampling schedule for VOCs to a biennial (every other year) schedule. The first event will occur in
April 2024 (approximately two years after the recent PFAS sampling event). During each event,
groundwater samples will be collected from wells FPC-MW-03, FPC-MW-07A, MW-2, MW-2A,
GM-1, and GM-5 for VOCs by USEPA Method 8260B.
In order to monitor PFAS impacts in Site monitoring wells, annual sampling for PFAS will begin in
April 2024 for selected monitoring wells, including wells FPC-MW-01, FPC-MW-07A, MW-2,
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Caldwell County - CAL/CAL.005 - CMS 14

SMARTER ENVIRONMENTAL SOLUTIONS

MW-2A, MW-3, MW-3A, GM-4, GM-5, and GM-6. Samples will be analyzed for the PFAS
constituents detected during the initial sampling events by USEPA Draft Method 1633 or USEPA
Modified Method 537.1 (or as directed by NCDEQ).
During each sampling event, a full round of water level measurements will be collected from the
existing monitoring wells. Samples will be collected utilizing low-flow/low-stress sampling
methods in accordance with USEPA LSASD protocols using a peristaltic pump and high -density
polyethylene (HDPE) tubing, where feasible. Where the depth to water precludes the use of a
peristaltic pump, a PVC bailer or stainless -steel submersible pump will used to collect groundwater
samples utilizing the multi -volume purge method outlined in the LSASD. Field measurements of
pH, temperature, specific conductivity, ORP, and turbidity will be collected during sampling.
Groundwater samples for PFAS analysis will be collected in accordance with LSASD protocols and
best practices for PFAS. QA/QC samples will be collected to assess the field sampling and
analytical programs. The QA/QC samples will include the collection of at least one duplicate, one
field blank, and one equipment rinse blank per sampling event.
Monitoring will continue under the schedule listed above through at least 2026 (three years).
Monitoring will cease at each sampling location if all constituents are below 2L Standards (or USEPA
MCLs and RSLs for PFAS) for three consecutive monitoring events. If groundwater concentrations
continue to decline, with NCDEQ approval, monitoring will transition to a prolonged schedule until
groundwater concentrations are at or below 2L Standards or subsequently defined risk -based
remediation goals. The proposed monitoring schedule for 2027 and subsequent events will be
included in the 2025 groundwater monitoring report.
Following each monitoring event, a groundwater monitoring report will be prepared and submitted to
NCDEQ. The report will document current groundwater concentrations and evaluate VOCs and
PFAS over time. Groundwater monitoring reports will include water -level measurements, laboratory
analytical data, field measurements, data tables, and other information as appropriate. Copies of the
laboratory analytical report and chain of custody documentation will also be included in the
monitoring reports.

6.0 Contingency Plans
In the event that groundwater monitoring data indicate that additional actions are needed for
protection of human health or the environment, recommendations for additional monitoring or other
actions will be made in the annual groundwater monitoring reports for the site. If the data suggest
that alternate corrective measures may be warranted, such as actions to address PFAS concentrations
or a switch to a risk -based remediation approach, those corrective measures would be detailed in a
CMS Addendum. H&H expects that recommendations related to PFAS may evolve as additional
data is collected by the scientific community regarding this emerging contaminant.

Notes:
2L Groundwater Standards have not been established by the North Carolina Department of Environmental Quality (NCDEQ) for PFAS. Concentrations are compared to the INC Interim Maximum
Allowable Concentration (IMAC), where established, as well as United States Environmental Protection Agency (USEPA) screening levels, as indicated below.
1 = USEPA Interim Health Advisory Level (June 2022)
2 = USEPA Final Health Advisory Level (June 2022)
3 = USEPA Tapwater Regional Screening Level (RSLs) based on target carcinogenic risk of 1 E-06 and target hazard quotient of 1.0 (May 2023)
4 = USEPA Proposed Maximum Contaminant Level (MCL; March 2023). For PFOA and PFOS, concentrations are directly compared to the MCL. For PFNA, PFHxS, and PFBS, the hazard index
is calculated for comparison to the MCL.
' = NC Interim Maximum Allowable Concentration (IMAC, April 1, 2022'
Italicized values indicate concentrations above the USEPA Interim or Final Health Advisory Levels.
Underlined values indicate concentrations above the USEPA RSLs for Tapwater.
Bold values indicate concentrations above the USEPA Proposed MCLs.
Concentrations were not detected above NC IMACs.
PerOuoroalkyl and polyfluoroalkyl substances (PFAS) concentrations are reported in nanograms per liter (ng/L).
Equipment blanks collected from a decontaminated water level meter during each sampling event, except for Equipment Blank 3, which was collected from the decontaminated stainless steel
submersible pump used at DW-1 on 4/13/23.
< PQL = Constituent not detected at concentrations above the practical quantitation limit (PQL). Table shows PFAS constituents detected at concentrations above PQLs.
E = Result exceeded calibration range
I = Value is estimated maximum possible concentration (EMPC)
NA = Not Applicable
NE = Not Established
QA/QC = Quality Assurance/Quality Control

Environmental Quality
RE: Request for information related to potential Environmentally Sensitive Areas/State-
Designated Area for Protection on or adjacent to the property located at 1200 Drag Strip Road,
Hudson, Caldwell County, North Carolina.
In reviewing the information on the property located at 1200 Drag Strip Road, Hudson, Caldwell
County, North Carolina, and the surround area, I have determined that this area is classified as
"Environmentally Sensitive" or "State -Designated Areas for Protection or Maintenance of
Aquatic Life".
Project Area
Watersheds are often named and referenced by their hydrologic unit codes (HUC). The project
area listed above is located on the ridge of two sub -watersheds in the Catawba River basin. The
western edge of the property drains to Brushy Fork [AU# 11-55-1-1] in the Rhodhiss Lake -
Catawba River watershed (HUC 0305010108) and the rest of the property drains to Pilot Branch
[AU# 11-58-4] in the Lake Hickory -Catawba River watershed (HUC 0305010109). Brushy Fork
drains into an impaired segment of Gunpowder Creek. Both Brushy Fork and Pilot Branch
ultimately drain to Lake Hickory. See the photos below; the blue highlighted portion is the
watershed listed in the table on the photo.
Water Quality Classifications and Assessments
One mechanism used by state and federal agencies to manage and protect streams, rivers,
lakes and other surface waterbodies is to establish surface water classifications. Each
classification has water quality standards associated with it. In North Carolina, the water quality
standards are used to determine if the waterbody is meeting or exceeding water quality
standards. Many of the classifications, especially those designated to protect drinking water
supplies and certain high -quality waterbodies, have rules in place that regulate activities (i.e.,
development, permitted discharge, etc.) that may impact water quality. Depending on the
classification, adjacent waterbodies may have the same restrictions.

NORTH CAROLINA 919.707.9000
Deportment of Envlmnmenbl Q..Ii�

This property is located in a watershed classified as C and then drains to Lake Hickory which is
classified as WS-IV, B, CA. Waterbodies classified as WS-IV are defined as "waters used as sources
of water supply for drinking, culinary or food processing purposes where WS-I, II, or III
classifications are not feasible." The critical area (CA) is the area "% mile and draining to water
supplies as measured from the normal pool elevation of reservoirs or % mile and draining to a
river (water supply) intake." Because of its classification as a water supply, additional protection
measures are in place to protect the water supply as a drinking water source for the surrounding
municipalities. Waters classified as C are protected for uses such as aquatic life propagation,
survival, and maintenance of biological integrity (including fishing and fish), wildlife, secondary
contact recreation (wading and boating), and agriculture. Waterbodies classified a class B add an
additional protection for primary recreation, which include activities that involve human body
contact with surface waters such as swimming, water skiing and skin diving. More information
about classifications, water quality standards, and measures in place to protect a waterbody's
use can be found on DWR's Classifications, Standards & Rules Review Branch's website.
Gunpower Creek [AU# 11-55-(1.5)] is listed on the EPA approved NC 2022 303(d)/305(b)
(Integrated Report) of Impaired Waters due to a Fair benthic macroinvertebrate community
rating. This watershed also has very high instream fecal coliform bacteria concentrations.
It is imperative that any activity taking place at this location eliminate runoff that would further
degrade the fragile systems that surrounds this area. There is a need to reduce the stormwater
volume, nutrients, sediment, and bacteria loading from this site. It is also imperative to address
any groundwater contamination that could be contributing pollutants in base flow to these
streams.

Mike,
Good morning. We are updating a previous receptor survey completed in 2017 at the request of the NCDEQ Hazardous
Waste Section for a project site in Hudson, North Carolina.
Please let us know if there are any Areas Identified Under Coastal Protection Legislation, Coastal Barriers, or Units of a
Coastal Barrier Resource System or any other sensitive environments within 1 mile of the site property, which is located
at 1200 Drag Strip Road in Hudson, NC (Caldwell County).
Please find the attached map for reference. If you need any other information from me for this survey, please let me
know.
Thanks, Carlin

Nora/Ian —
Good morning. We are updating a previous receptor survey completed in 2017 at the request of the NCDEQ Hazardous
Waste Section for a project site in Hudson, North Carolina.
Please let us know if there are any updates to the response below (provided by Melanie Williams in November 2017) for
any State -Designated Areas for Protection or Maintenance of Aquatic Life or any other sensitive environments within 1
mile of the site property, which is located at 1200 Drag Strip Road in Hudson, NC (Caldwell County).
Please find the attached map for reference. If you need any other information from me for this survey, please let me
know.
Thanks, Carlin

Ms. Randolph,
The property located at 1200 Drag Strip Rd, Hudson, NC 28638 is in the Catawba River Basin and drains to Brushy Fork
[AU#: 11-55-1.1] which then drains to Gunpowder Creek [AU#: 11-55-(1.5)]. Brushy Fork is currently not monitored by
the DWR; however, Gunpowder Creek is listed on the draft 2016 and the final 2014 Integrated Report as Impaired for
declining benthos populations.
Seeing that this property drains to an impaired stream, it is suggested to take the precautions needed to protect the
stream from further impacts. Both Brushy Fork [AU#: 11-55-1.1] and Gunpowder Creek [AU#: 11-55-(1.5)] are both
currently considered to be in environmentally sensitive areas for the protection and maintenance of aquatic life.
Additional water quality information and recommendations specifically concerning Brushy Fork and Gunpowder Creek
can be found in Chapter 1 of the 2010 Catawba River Basinwide Water Quality Plan. Please let me know if you have any
further questions or concerns.

like to know if there are any State Wild & Scenic Rivers or any other sensitive environments within 1 mile of my site
property, which is at 1200 Drag Strip Road in Hudson, NC (Caldwell County).
Please find the attached map for reference. If you need any other information from me for this survey, please let me
know.
Thank you,

Hi Carlin,
I ran this project through our Information for Planning and Consultation System (IPAC). Attached is a
preliminary list of species that would need to be addressed during project review. I did an approximate
boundary but you can access the site and upload a SHP for more exact boundaries.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical
habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's
(USFWS) jurisdiction that are known or expected to be on or near the project area referenced
below. The list may also include trust resources that occur outside of the project area, but
that could potentially be directly or indirectly affected by activities in the project area.
However, determining the likelihood and extent of effects a project may have on trust
resources typically requires gathering additional site -specific (e.g., vegetation/species X%46
surveys) and project -specific (e.g., magnitude and timing of proposed activities) information.
Below is a summary of the project information you provided and contact information for the
USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to
each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI
Wetlands) for additional information applicable to the trust resources addressed in that
section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis
of project level impacts.
The primary information used to generate this list is the known or expected range of each
species. Additional areas of influence (AOI) for species are also considered. An AOI includes
areas outside of the species range if the species could be indirectly affected by activities in
that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at
the dam site, may indirectly impact the species by reducing or eliminating water flow
downstream). Because species can move, and site conditions can change, the species on this
list are not guaranteed to be found on or near the project area. To fully determine any
potential effects to species, additional site -specific and project -specific information is often
required. _,P V
Section 7 of the Endangered Species Act requires Federal agencies to "request of the
Secretary information whether any species which is listed or proposed to be listed may be
present in the area of such proposed action" for any project that is conducted, permitted,
funded, or licensed by any Federal agency. A letter from the local office and a species list
which fulfills this requirement can only be obtained by requesting an official species list from
either the Regulatory Review section in IPaC (see directions below) or from the local field
office directly. <X ,I

Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely
to be present in your project area. This information can be used to tailor and schedule your
project activities to avoid or minimize impacts to birds. Please make sure you read and
understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before
using or attempting to interpret this report.
Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cells)
your project overlaps during a particular week of the year. (A year is represented as 12 4-
week months.) A taller bar indicates a higher probability of species presence. The survey
effort (see below) can be used to establish a level of confidence in the presence score. One
can have higher confidence in the presence score if the corresponding survey effort is also
high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in
the week where the species was detected divided by the total number of survey events
for that week. For example, if in week 12 there were 20 survey events and the Spotted
Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in
week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of
presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence
at week 12 (0.25) is the maximum of any week of the year. The relative probability of
presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the
probability of presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season (
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds
across its entire range. If there are no yellow bars shown for a bird, it does not breed in your
project area.
Survey Effort (1)

2/14/23, 8:30 AM
IPaC: Explore Location resources
Vertical black lines superimposed on probability of presence bars indicate the number of
surveys performed for that species in the 10km grid cell(s) your project area overlaps. The
number of surveys is expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data (—)
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are
based on all years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory
birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all
birds at any location year round. Implementation of these measures is particularly important when birds
are most likely to occur in the project area. When birds may be breeding in the area, identifying the
locations of any active nests and avoiding their destruction is a very helpful impact minimization measure.
To see when birds are most likely to occur and be breeding in your project area, view the Probability of
Presence Summary. Additional measures or permits may be advisable depending on the type of activity
you are conducting and the type of infrastructure or bird species present on your project site.
What does IPaC use to generate the list of migratory birds that potentially occur in my specified
location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC), and other
species that may warrant special attention in your project location.

IPaC: Explore Location resources
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge
Network (AKN). The AKN data is based on a growing collection of survey., banding, and citizen science
datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid
cell(s) which your project intersects, and that have been identified as warranting special attention because
they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a
particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area.
It is not representative of all birds that may occur in your project area. To get a list of all birds potentially
present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially
occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by
the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey., banding, and
citizen science datasets.
Probabilityof presence data is continuous) being updated as new and better information becomes T

available. To learn more about how the probability of presence graphs are produced and how to interpret
them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering or migrating in my area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering,
migrating or year-round), you may query your location using the RAIL Tool and look at the range maps
provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a bird
on your migratory bird species list has a breeding season associated with it, if that bird does occur in your
project area, there may be nests present at some point within the timeframe specified. If "Breeds
elsewhere" is indicated, then the bird likely does not breed in your project area.
A
What are the levels of conV
r migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
"BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their
range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin
Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in
the continental USA; and
3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either
because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in
offshore areas from certain types of development or activities (e.g. offshore energy development or
longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in
particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of
rangewide concern. For more information on conservation measures you can implement to help avoid and
minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

For additional details about the relative occurrence and abundance of both individual bird species and
groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data
Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to
you in your project review. Alternately, you may download the bird model results files underlying the portal
maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird
Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use throughout the
year, including migration. Models relying on survey data may not include this information. For additional
information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact
Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating
the Eagle Act should such impacts occur.

Proper Interpretation and Use of Your Migratory Bird Report X�. 0\�
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of
priority concern. To learn more about how your list is generated, and see options for identifying what
other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory
birds potentially occurring in my specified location". Please be aware this report provides the "probability
of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project
footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black
vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is
the key component. If the survey effort is high, then the probability of presence score can be viewed as
more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a
lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for
identifying what birds of concern have the potential to be in your project area, when they might be there,
and if they might be breeding (which means nests might be present). The list helps you know what to look
for to confirm presence, and helps guide you in knowing when to implement conservation measures to
avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn
more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement
to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources
page.

conducted. Metadata should be consulted to determine the date of the source imagery used and any
mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There
may be occasional differences in polygon boundaries or classifications between the information depicted
on the map and the actual conditions on site.
Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of
aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or
submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and
nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also
been excluded from the inventory. These habitats, because of their depth, go undetected by aerial
imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe
wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or
products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local
government or to establish the geographical scope of the regulatory programs of government agencies.
Persons intending to engage in activities involving modifications within or adjacent to wetland areas should
seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory
programs and proprietary jurisdictions that may affect such activities.

No additional comments.
Job ID: 320-96418-1
Receipt
The samples were received on 1/31/2023 10:15 AM. 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 was 1.21 C.
Receipt Exceptions
The container label for the following samples did not match the information listed on the Chain -of -Custody (COC): MW-3A (320-96418-7)
and GW-DUP (320-96418-8). The containers for sample MW-3A (320-96418-7) were labeled with a collection date of 1/26/23. The
containers for sample GW-DUP (320-96418-8) were labeled with a collection date of 1/27/23. As requested, a collection date of 1/27/23
was used for both samples.
LCMS I
Method 537 (modified): The laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for preparation batch
320-651321 and analytical batch 320-655097 recovered outside control limits for the following analyte: 11 CI-PF3OUdS. This analyte was
biased high in the LCSs and was not detected in the associated samples; therefore, the data have been reported.
Method 537 (modified): The "I" qualifier means the transition mass ratio for the indicated analyte was above the established ratio limits.
The qualitative identification of the analyte has some degree of uncertainty, and the reported value may have some high bias. However,
analyst judgment was used to positively identify the analyte. The following samples are impacted: GM-1 (320-96418-1) and MW-3
(320-96418-6).
Method 537 (modified): The concentration of one or more analytes associated with the following samples exceeded the instrument
calibration range: GM-1 (320-96418-1) and GW-DUP (320-96418-8). These analytes have been qualified with an 'E' flag; however, the
peaks did not saturate the instrument detector. Historical data indicate that for the isotope dilution method, dilution and re -analysis will not
produce significantly different results from those reported above the calibration range.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Organic Prep
Method 3535: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with
preparation batch 320-651321.
Method 3535: The following samples in preparation batch 320-651321 were observed to have a thin layer of sediment present in the
bottom of their bottles prior to extraction. GM-1 (320-96418-1), GM-5 (320-96418-2), FPC-MW-07A (320-96418-3), MW-2 (320-96418-4),
MW-2A (320-96418-5), MW-3 (320-96418-6), MW-3A (320-96418-7) and GW-DUP (320-96418-8)
Method 3535: The following samples in preparation batch 320-651321 were tan in color prior to extraction. GM-5 (320-96418-2), MW-2A
(320-96418-5) and MW-3 (320-96418-6)
Method 3535: During the solid phase extraction process, the following samples contain non-settable particulates which clogged the solid
phase extraction column: GM-1 (320-96418-1), GM-5 (320-96418-2), FPC-MW-07A (320-96418-3), MW-2A (320-96418-5), MW-3A
(320-96418-7) and GW-DUP (320-96418-8).
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Receipt
The samples were received on 4/18/2023 9:55 AM. 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 was 3.10 C.
Receipt Exceptions
No date was listed on the chain of custody for sample DUP-2. As requested, a date of 4/12/23 was used in the report. The containers for
FPC-MW-01 are labeled with a time of 16:04. The time listed on the COC was used in the report.
The container label for the following sample(s) did not match the information listed on the Chain -of -Custody (COC): COCFPC-MW-01
(320-99004-1). The containers for this sample were labeled with a collection time of 16:04. The collection time listed on the chain of
custody was used in the report.
LCMS I
Method 537 (modified): The continuing calibration verification (CCV) associated with batch 320-669442 recovered above the upper control
limit for 4,8-Dioxa-3H-perfluorononanoic acid (ADONA). The sample results associated with this CCV were non -detects for the affected
analyte; therefore, the data have been reported.
Method 537 (modified): The continuing calibration verification (CCV) associated with batch 320-669439 recovered above the upper control
limit for 4,8-Dioxa-3H-perfluorononanoic acid (ADONA). The sample results associated with this CCV were non -detect for the affected
analyte; therefore, the data have been reported.
Method 537 (modified): The laboratory control sample (LCS) for preparation batch 320-669614 and analytical batch 320-670709 recovered
outside control limits for the following analyte: 11 CI-PF30UdS. This analyte was biased high in the LCS and was not detected in the
associated samples; therefore, the data have been reported.
Method 537 (modified): Two Isotope Dilution Analyte (IDA) recoveries are above the method recommended limit for the following sample:
MW-C (320-99004-6). Quantitation by isotope dilution generally precludes any adverse effect on data quality due to elevated IDA
recoveries.
Method 537 (modified): The concentration of one or more analytes associated with the following sample exceeded the instrument
calibration range: DW-1 (320-99004-7). These analytes has been qualified with an 'E' flag; however, the peaks did not saturate the
instrument detector. Historical data indicate that for the isotope dilution method, dilution and re -analysis will not produce significantly
different results from those reported above the calibration range.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page
Organic Prep
Method 3535: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with
preparation batch 320-668932.
Method 3535: The following sample in preparation batch 320-668932 was observed to have a thin layer of sediment present at the bottom
of its bottle prior to extraction. DUP-2 (320-99004-8)
Method 3535: During the solid -phase extraction process, the following sample in preparation batch 320-668932 contained non-settable
particulates which clogged the solid -phase extraction column: DUP-2 (320-99004-8).
Method 3535: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with
preparation batch 320-669614.
