Subject: Preliminary Assessment (PA) Report
Kayser-Roth Corporation
NONCD0001947
Lumberton, Robeson County, NC
Dear Ms. Bramble:
Under authority of the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 (CERCLA) and the Superfund Amendments and Reauthorization Act of
1986 (SARA), the North Carolina Superfund Section conducted a Preliminary Assessment (PA)
at the Kayser-Roth Corporation site, (NONCD0001947) Lumberton, Robeson County, NC.
Information on the site was obtained through the review of available state and county file
documents, North Carolina State and Robeson County Geographic Information Services (GIS),
and available reports and work plans regarding on site environmental monitoring and assessment
activities.
The purpose of this PA was to evaluate environmental conditions at the site to determine
the need for remedial activities under the CERCLA program, as there may be potential for vapor
intrusion at the plant facility and nearby off-site structures in addition to contamination of
groundwater and surface water. The site consists of two areas contaminated by chlorinated
solvents: a volatile organic compound (VOC) plume in groundwater originating underneath the
plant facility on the western side of the property, and a dense non-aqueous phase liquid (DNAPL)
source and groundwater plume at a former wastewater lagoon area located in the northeastern
corner of the property. The current focus of this PA is to evaluate the potential for exposure via
subsurface intrusion at structures and properties located near the Kayser-Roth manufacturing
facility.

Site Location and Description:
The Kayser-Roth site is located at 3707 West 5th Street, Lumberton, Robeson County, North
Carolina 28358 (see Figure 1). The geographic coordinates for the site are 34.61320 north latitude
and -79.06838 west longitude (Ref. 3).
The site consists of a 234,074 square foot plant facility on a 63.48-acre lot. The remaining property
consists of either grass-covered area, or asphalt-covered parking lots located northwest and
northeast of the building, which are connected by a driveway that surrounds the plant facility (Refs.
4, 5) (see Figure 2).
The Kayser-Roth property frontage is bounded to the northwest by West 5th Street, which runs
parallel to the south side of Interstate 95 (I-95/301). Kenric Road runs parallel to the north side of
I-95. The Lumberton Regional Airport borders much of the Kayser-Roth property line to the east,
and a city-owned parcel to the south-east is used as agricultural/crop land. Additional agricultural,
undeveloped and vacant properties exist to the south and southwest of the property. A former
industrial facility, located adjacent to the northeastern section of the property, was historically used
to produce textiles (Temptations Hosiery, Sara Lee Corporation), and later operated as a printing
facility (Culp Inc), and was most recently procured by I95 Lumberton Transfer LLC. The building
on the property has been removed, but the concrete foundation lab remains. Mt. Haven Church is
located adjacent to the northwestern corner of the Kayser-Roth property boundary. A mix of
commercial and residential use properties are located to the west of the site and also to the north
along Kenric Road across I-95/Route 301. Farther to the north is Lumber River State Park. The
Lumber River is located approximately 1500 ft from the Kayser-Roth property line, with
designated wetlands less than 600 ft north of the property line (Refs. 4, 5, 6).
History of Ownership and Site Operations:
Kayser-Roth Manufacturing Facility:
Textured Fibers Inc. (Texfi) purchased the property in 1968. Texfi operated as a textile dying,
finishing, and manufacturing facility. Kayser-Roth acquired the facility in 1978 and continued to
knit, sew, and dye textile products. Based on historical aerial photographs, the manufacturing
facility structure and wastewater retention pond was constructed in 1969, and the structure was
expanded in the 1970s, the early 2000’s, and in 2009 (Refs. 4, 7).

Former Wastewater Lagoon area:
The City of Lumberton purchased the property that contained the former wastewater lagoon on
April 1, 1969. According to a September 1997 affidavit from the City Manager for Lumberton,
the wastewater lagoon was constructed in 1969 on land recently purchased by the City of
Lumberton, and was used as an aeration basin for effluent from the Texfi facility and the adjacent
Temptations Hosiery textile facility to the northeast. The intent was for the aeration basin to serve
as a pre-treatment facility once the City treatment facilities were constructed in 1970. In 1972, a
request was made by Texfi to tie directly into the sewer lines to allow bypass of the lagoon in order
to clean out the lagoon and to make necessary repairs. The City sold the lagoon property parcel to
Texfi on August 7, 1975, and the parcel was included in the larger facility sale to Kayser-Roth in
1978 (Ref. 8).
The September 1997 affidavit disputed claims (reportedly cited in reports prepared by Kayser
contractors) that the wastewater lagoon had formerly been used as an overflow pond for a nearby
municipal sewage pump station. The affidavit included documentation that indicated the lagoon
was constructed solely for the use of Texfi (and possibly adjacent Temptations Hosiery) for pre-
treatment of effluent prior to discharge into the city wastewater system. The 1997 affidavit asserted
that these two companies were the only potential dischargers to the lagoon during the period of the
City’s ownership of the lagoon site, and indicated that in 1974, Texfi had been the only user of the
lagoon (Ref. 8) .
Site Regulatory History:
Available records indicate that site regulatory activity to date has been overseen entirely by the
State of NC (NC Department of Environment & Natural Resources [NCDENR], later the NC
Department of Environmental Quality [NC DEQ]). Groundwater and soil contamination by
tetrachloroethene (PCE) and other chlorinated volatile organic compounds (cVOCs) was first
identified by private environmental contractor investigations in the late 1990s (Refs. 9, 10).
Subsequent groundwater monitoring by contractors has continued to document cVOC
groundwater contamination beneath the site.
In 2008 and also in 2019, the Inactive Hazardous Sites Branch (IHSB) of the NC Department of
Environmental Quality sent letters to Kayser-Roth explaining that Kayser-Roth would need to
enter into an REC-AA (Registered Environmental Consultant – Administrative Agreement) in
order to receive approval for a remedial action; if the responsible party opted out of the REC-AA,
an alternative would be to perform remedial activities independently, with no State oversight or
approval (Refs. 11, 12). Kayser-Roth declined to participate in the REC program for the
Lumberton site in 2008 (Ref. 13). Since that time, Kayser-Roth has continued to conduct
independent remedial assessment and cleanup activities at the site, communicating results and
activities on a voluntary basis without IHSB oversight or approval.

Former Wastewater Lagoon area – Soil and Groundwater:
In 1996, groundwater contamination was discovered during an environmental site assessment,
conducted at the adjacent property east/northeast of Kayser-Roth prior to the former property’s
purchase by Culp Printing from the Sara Lee Corporation. It was determined the likely source of
the contamination was the wastewater lagoon located on the northeastern corner of the Kayser-
Roth property, directly adjacent to the Sara Lee property. Kayser-Roth contractors conducted a
limited assessment, which included sampling the lagoon wastewater and sludge, and installing
monitoring wells near the lagoon for the collection of groundwater samples (Refs.10, 14.
Sampling confirmed the presence of cVOCs in the lagoon sludge and in adjacent groundwater. In
February 1997, the State of North Carolina was informed of the presence of cVOCs in the
groundwater near the open wastewater lagoon. Contaminants present included (Ref. 15). In July
1997, the State issued a Notice of Violation to the Kayser-Roth Corporation for exceeding the 15A
North Carolina Administrative Code (NCAC) 2L groundwater standards for cis-1,2-DCE, TCE,
PCE, vinyl chloride, and 1,4-dichlorobenzene and assigned incident number #17125 (Refs. 13, 16).
Kayser-Roth contested they were not responsible for the release as they did not ever use or store
the chlorinated solvents at the Lumberton facility and that the City of Lumberton originally owned
the lagoon property and used the lagoon for sewage overflow (Ref. 17). However, the September
1997 City of Lumberton affidavit countered that the lagoon was constructed for and used by Texfi
and that the City did not ever use the lagoon (Ref. 8). A 1999 letter from the NC Department of
Environment and Natural Resources to Kayser-Roth stated that they had failed to reveal the cause
of contamination, or when it first occurred. Therefore Kayser-Roth, as the current landowner, was
deemed by the State to be in control of a secondary source of contamination and subject to the
requirements of NCAC 2L.0106 (b) and (c). Kayser-Roth was then directed to take immediate
action to eliminate the sources of contamination, to submit a report assessing cause, significance,
and extent of the violation, and to implement an approved corrective action plan (CAP) for
restoration of groundwater quality (Ref. 18).
In October 2003, consultants for Kayser-Roth notified NC DENR of plans to close the wastewater
lagoon. The letter indicated that a CAP would be developed to address impacted groundwater in
that area (Ref. 19). According to the lagoon closure report, the lagoon was dewatered and
>500,000 gallons of effluent waste was discharged into the City of Lumberton publicly-owned
treatment works (POTW) for treatment, as agreed upon with the City. Approximately 280 tons of
sludge was excavated from the site and removed, and the solidified sludge transported offsite for
hazardous disposal. The lagoon area was then backfilled with clean fill from an off-site source
(Refs. 4 (aerial images), 20, 21) .

In 2003, Kaiser contractors completed a CAP to address Incident #17125 (Ref. 22). However, the
CAP (and multiple other monitoring reports referencing Incident #17125) addressed only the VOC
plume under the plant facility, and not the groundwater plume beneath the former wastewater
lagoon. Although no separate/specific CAP for the previous lagoon area has been identified to date,
site contractors conducted quarterly and then semi-annual to annual groundwater monitoring at
the lagoon until early 2009 (Refs. 21, 22, 24).
An annual groundwater monitoring report prepared in July 2016 identified dense non-aqueous
phase liquid (DNAPL) cVOCs near the edge of the active lagoon (Ref. 25). In August 2016, the
IHSB concurred with recommendations in the monitoring report, including additional assessment
to delineate the DNAPL source and a well survey of nearby properties. The 2016 letter from IHSB
also noted that groundwater samples had not been analyzed for 1,4-dioxane, and requested the
development of a work plan to delineate the extent of all contaminant plumes at the site (Ref. 26).
Kayser-Roth Manufacturing Facility – Soil and Groundwater:
A comprehensive site assessment report on the Kayser-Roth manufacturing facility portion of the
site cited 1999 sampling data documenting that concentrations of PCE, TCE, 1,1-DCE, and 1,2-
DCE in shallow groundwater near the plant facility exceeded North Carolina NCAC 2L
groundwater standards. The assessment included installation and replacement of monitoring wells
near the plant area that had been damaged by facility construction/expansion activities (Ref. 9).
The CAP prepared in 2003 recommended monitored natural attenuation of the facility groundwater
contaminant plume as the preferred remedial option (Ref. 22). The NC DENR approved the CAP
in February 2004 (Ref. 27). Kayser-Roth contractors subsequently conducted quarterly and later
annual groundwater monitoring at the plant facility, submitting results and recommendations to
NC DEQ (Refs. 25, 28).
In Feb 2016, in response to a 2015 groundwater monitoring report, the IHSB requested that
Kayser-Roth conduct an expanded well survey to identify potential receptors within 1500 ft of the
site (Ref 26). In October 2016, Kayser-Roth contractors submitted an initial workplan to conduct
additional work at the Kayser-Roth Lumberton site. The workplan outlined plans to further
investigate the two site groundwater contaminant plumes (Ref. 29). The expanded receptor survey
was completed in 2017 (Ref. 30), and three amended workplans were submitted in 2018, 2019 and
2020, including maps of current site monitoring wells and 2018 groundwater contaminant
concentrations, and provision for a site-wide groundwater monitoring event (Refs. 31, 32, 33).

Surface Water:
A 2018 monitoring report prepared for Kayser-Roth identified a surface water ditch (near shallow
well NEMW-1) located north of I-95 across from the former wastewater lagoon. The ditch flows
west-northwest along I-95, turns north, and drains further to the northwest. Surface water samples
collected from the ditch in November 2018 and January 2019 contained vinyl chloride at
concentrations (up to 130 micrograms per liter [µg/L]) that exceeded the NC Class WS (I-V) 2B
standard. Groundwater samples from two off-property monitoring wells and temporary monitoring
wells installed adjacent to the ditch contained vinyl chloride (up to 7,920 µg/L) exceeding the (2
µg/L) MCL. Kayser-Roth coordinated with NCDEQ and the property owner (National Erectors
Rebar, Inc) to post a sign along the ditch indicating that the surface water was contaminated and
that contact with surface water and shallow groundwater in the area should be avoided. The
workplan amendments prepared by Kayser-Roth contractors in 2019 indicated that surface water
sampling would be conducted twice per year (Refs. 2, 31, 32, 33).
Subsurface Intrusion:
After reviewing a 2015 Kayser-Roth groundwater monitoring report, the IHSB cited a potential
cVOC subsurface intrusion (SsI) hazard to facility workers, and recommended that Kayser-Roth
conduct screening for subsurface (vapor) intrusion at facility structures. After completing initial
on-site soil gas and sub-slab soil gas monitoring in November 2018, Kayser-Roth contractors
updated the site workplan to include additional subsurface intrusion assessment within the facility
structure (Refs. 32, 34) .
April 2020 (Ref. 33):
•Fourteen indoor air locations were sampled (4-day exposure) using Beacon Passive Indoor
Air (PIA) samplers.
•Normal plant operation with air rotation equipment operating and (internal) fire doors open
(6 AM to 3PM) and off/closed (6 PM to 3 AM).
•PCE detected in all samples, exceeding NC Non-residential Indoor Air Screening Level
(NIASL: 35 µg/m3) at two locations and EPA Regional Screening Level (RSL; 18 µg/m3
[Ref. 35]) at four locations. Maximum concentration: 133 µg/m3.
•TCE detected in eleven samples, exceeding NC NIASL (1.8 µg/m3) at four locations and
RSL (0.88 µg/m3) at seven locations. Maximum concentration: 17.2 µg/m3.

May 2020 (Ref. 33):
•Three indoor air locations were re-sampled (8-hour exposure) using Summa Canisters.
•Indoor air purifying units (APUs) activated and air rotation equipment operating 24 hours.
•PCE detected in all samples, exceeding NC NIASL and RSL at all locations. Maximum
concentration: 78 µg/m3 (140 µg/m3 pre-activation).
•TCE detected in all samples, exceeding NIASL at one location and RSL at all locations.
Maximum concentration: 1.4 µg/m3.
•Pre-activation concentrations input to NC RCT: PCE generated Carcinogenic Risk of 3.0E-
6 and non-carcinogenic Hazard Quotient of 0.8. TCE generated Carcinogenic Risk of 6.4E-
6 and non-carcinogenic Hazard Quotient of 0.22 (Ref. 33 Appendix B).
•EPA Vapor Intrusion Screening Level (VISL) calculator analysis of maximum post-
activation PCE and TCE concentrations generated combined Carcinogenic Risk of 2.12 E-
6 and HQ of 0.605 (Ref. 36).
June 2020 (Ref. 33):
•Five indoor air locations were re-sampled and two floor trench locations were sampled (8-
hour exposure) using Summa Canisters.
•Indoor APUs off with air rotation equipment operating 24 hours and air washer unit
(supplying most of facility) operating (approximately 5 to 11 PM) daily.
•PCE detected in all samplers, exceeding NC NIASL and RSL at all locations. Maximum
concentration: 150 µg/m3.
•TCE detected in all samplers, below NIASL but exceeding RSL at five locations.
Maximum concentration: 1.2 µg/m3.
•Maximum concentrations input to NC RCT: PCE generated Carcinogenic Risk of 3.18E-
6 and non-carcinogenic Hazard Quotient of 0.856. TCE generated Carcinogenic Risk of
4.01 E-7 and non-carcinogenic Hazard Quotient of 0.137 (Ref. 33 Appendix B) .
•EPA Vapor Intrusion Screening Level (VISL) calculator analysis of maximum PCE and
TCE concentrations generated combined Carcinogenic Risk of 3.58E-6 and HQ of 0.993
(Ref. 36).
June 2020 indoor air sampling results indicated further reduction in indoor air PCE and TCE
concentrations. Although PCE still exceeded Non-Residential Screening Levels, evaluation using
the NCDEQ RCT indicated that concentrations did not pose an unacceptable risk level (Ref. 33).
July 2020 (Ref. 33):
•Six indoor air locations re-sampled and eleven floor trench locations sampled (8-hr) using
Summa Canisters.
•Indoor APUs on with air rotation equipment operating 24 hours and air washer unit

•PCE detected in all samples, exceeding NC NIASL at one indoor air and one trench
location, and RSL at three indoor air locations and one trench location. Maximum
concentration: 78 µg/m3.
•TCE detected in all samplers, exceeding RSL at two indoor air locations. Maximum
concentration: 1.8 µg/m3.
•Maximum concentrations input to NC RCT: PCE generated Carcinogenic Risk of 1.7E-6

•EPA Vapor Intrusion Screening Level (VISL) calculator analysis of maximum PCE and
TCE concentrations generated combined Carcinogenic Risk of 2.26 E-6 and HQ of 0.651
(Ref. 36).
From late 2020 to the present Kayser Roth contractors continued to conduct indoor air monitoring
with quarterly sampling events, entering maximum PCE and TCE concentrations for each event
into the NC RCT and reporting results to the NC IHSB. Resulting calculated risk remained less
than 1.0E-4; HQ less than 1 for all events until early 2022, when an increase in concentrations
occurred. In response, in a May 11, 2022 communication to the IHSB, Kayser-Roth consultants
reported upcoming additional modifications to air circulation, maintenance and location
adjustment of APUs, confirmatory indoor air re-sampling, and an updated indoor survey for
products potentially containing PCE and/or TCE (Ref. 37).
On May 27, 2022, Kayser-Roth contractors reported to the IHSB that re-sampling had confirmed
excess risk posed by PCE and/or TCE air concentrations at the facility. During subsequent
communications in May, June and July 2022, the contractor reported that the plant had added to
its air filtering capacity by purchasing and replacing APUs. Sampling results from late June 2022
indicated a reduction of PCE and TCE concentrations. Detections of PCE (up to 122 µg/m3) and
TCE (up to 2.34 µg/m3) continued to exceed their IASLs and RSLs. Contractors reported they
were evaluating candidate subcontractors to seal floor cracks and other penetrations of the floor
slab, and planned to evaluate long-term options, including potential installation of a sub-slab
depressurization system (Ref. 37).
The IHSB acknowledged receipt of the above notices and requested confirmation that no
subsurface intrusion concerns existed for adjacent properties overlying the site’s groundwater
contaminant plumes. On May 19, 2022 Kayser-Roth contractors indicated that no such indoor air
concerns existed. Their conclusion was based upon results of a 2018 soil gas survey, which used
56 passive soil gas (PSG) samplers deployed at the site property and along the downgradient West
5th Street and Kenric Road right-of-ways (Ref. 32)(see Attachment 1). However, the (6-inch)
PSG sample borehole depths used in the study did not conform to the vendor’s (36-inch) sampling
protocol (Refs 32, 37, 38).

In October 2022, based on the ongoing worker exposure to indoor air contamination, the NC
Superfund Section Federal Remediation Branch (FRB) contacted the Superfund Section IHSB
regarding current and future remedial activities at the site. Following discussion with the IHSB,
Kayser-Roth contractors reported that the company had agreed to sign a REC administrative
agreement to address imminent hazards and long-term remediation of the indoor air contamination
with IHSB oversight. These actions will be conducted in accordance with stipulations outlined in
the written REC agreement and are anticipated to include but are not limited to the installation of
a sub-slab depressurization system and active subsurface source remediation. Kayser-Roth plans
to address the former wastewater lagoon portion of the site under a separate agreement with other
potentially responsible parties (Ref. 39).
Site Investigative History:
Various Kayser-Roth contractors have conducted multiple investigations at the site. Cumulative
results indicate that two separate cVOC plumes exist in groundwater beneath the site. One plume
lies beneath the textile manufacturing facility, and the second lies beneath the northwest corner of
the Kayser-Roth property, where the wastewater lagoon formerly operated.
Soil Investigations:
Former wastewater lagoon area:
An initial assessment in 1997 included analysis of a sludge sample collected from the existing
wastewater lagoon. The sample contained 2,200 milligrams per kilogram (mg/kg) of TCE and
20,000 mg/kg of PCE (Ref. 10, see Table 1 in the report). In 2003, as part of the lagoon closure,
contractors dewatered the lagoon, discharging approximately 500,000 gallons of wastewater to the
local sanitary sewer. Contractors then excavated and solidified approximately 300 tons of organic
sludge and transported it to an off-site hazardous waste disposal facility. The lagoon basin was
then backfilled with clean fill material from offsite (Ref. 21).
In 1999, during installation of monitoring wells in the area near the (then-existing) wastewater
lagoon, contractors collected soil samples from the unsaturated zone at three locations using
hollow stem augurs. High water table conditions prevented collection of samples from most of
the boreholes, but samples were obtained from one boring located next to the lagoon and from two
other boreholes located in a nearby agricultural field. Soil samples were collected at 5-foot
intervals, and screened for VOCs; from each borehole, the soil sample producing the highest
photoionization detector reading was submitted for laboratory analysis of VOCs by EPA method
8260. The only laboratory cVOC detection was (total) 1,2-DCE (7 µg/kg), from the borehole
adjacent to the lagoon (Ref. 10) .

Keyser-Roth Manufacturing Facility:
In 1999, five soil samples were collected near the manufacturing facility using Geoprobe® push-
coring technology. Three of the samples were collected adjacent to former or existing petroleum
fuel storage tanks. The soil samples were analyzed using EPA methods 8260 and 8270: Results
were non-detect for VOCs and semi-VOCs.
Four additional soil samples were collected from beneath the facility dye trenches by hand auger,
taken from a depth of approximately 3 feet, which was 1 foot below the base of the dye trench.
One of the samples from the dye trench contained 6 micrograms per kilogram (µg/kg) of PCE and
27 µg/kg of DCE, while the other three samples were non-detect for VOCs (Ref. 9).
Soil samples were also collected at 5ft depth intervals during the installation of eight shallow
monitoring wells near the facility in June 1999. Samples were not collected from one borehole due
to high water table conditions. PCE was detected in soil from the borehole for MW-3 (18 µg/kg)
which was located west of the building footprint at the time. PCE was also detected in the borehole
for MW-6 (110 µg/kg), located southwest of the building footprint in an asphalt parking lot (Ref.
9).
Groundwater Investigations:
Cumulative groundwater sampling results have identified two cVOC groundwater plumes at the
site property. The source area for the northeastern groundwater plume is the former wastewater
lagoon. The contaminant plume has migrated north-northwest beneath I-95 toward commercial
properties along Kenric Road and toward the Lumber River. Current monitoring well locations
and groundwater VOC sample results from the site’s surficial aquifer are illustrated in an August
2018 site assessment and workplan amendment report (Ref. 31).
The southwestern groundwater plume originated beneath the plant facility and is migrating
northwest towards adjacent residential properties. Contamination in groundwater from a source
at the plant facility was documented in a letter from Kayser-Roth to NC DENR dated May 21,
1999 and in a subsequent assessment report, indicating elevated concentrations of PCE and TCE
in groundwater samples exceeding state groundwater standards (Refs. 9, 19).
Environmental consulting contractors for Kayser-Roth have prepared multiple monitoring and site
assessment reports along with plans to address the plume near the former wastewater lagoon and
the plume near the plant facility. In earlier reports, the monitoring and assessment activities for
the lagoon and facility areas are presented in separate reports; reports dated after 2010 are
combined and present data for both plumes. Over time, some monitoring wells installed at the site
have been destroyed due to construction and other activities and additional wells have been
installed (Refs. 21, 23, 24, 25, 28, 31, 32, 33). Isoconcentration maps of PCE, TCE, DCE, vinyl
chloride, and 1,4-dioxane from the most recent sampling event conducted in November 2019 are
included in a December 2020 site assessment and workplan amendment report (Ref. 33).

Former wastewater lagoon area:
Groundwater contamination was first identified northeast of the (then-operational) wastewater
lagoon in late 1996, as part of an environmental site assessment performed prior to the sale of the
adjacent property. At that time, groundwater samples from the wells on the adjacent property
owned by the Sara Lee Corporation were found to contain elevated concentrations of chlorinated
VOCs including PCE (13 µg/L), TCE (up to 1,600 µg/L), (total) 1,2-DCE (up to 20,000 µg/L),
1,1-DCE (up to 92 µg/L), 1,1,1-TCA (350 µg/L), 1,1,DCA (up to 170 µg/L), and vinyl chloride
(up to 450 µg/L). (Refs 10, 15).
Kayser-Roth contractors conducted initial on-site assessment of the wastewater lagoon in early
1997, installing and sampling two groundwater monitoring wells at the lagoon and collecting a
sludge and a surface water sample from the lagoon. One or both groundwater samples contained
PCE and TCE (23,000 µg/L); cis-1,2-DCE (up to 89,000 µg/L), trans-1,2-DCE (up to 940 µg/L),
1,1-DCE (290 µg/L), 1,1,1-TCA (3,700 µg/L), 1,1-DCA (up to 540 µg/L), 1,4-dichlorobenzene
(up to 300 µg/L), chlorobenzene (5.2 µg/L) and vinyl chloride (up to 1,500 µg/L) (Refs. 10, 15).
Kayser-Roth contractors installed seven additional monitoring wells in June 1999. Groundwater
samples collected from the nine wells contained PCE (up to 5,300 µg/L), TCE (up to 280 µg/L),
(total) 1,2-DCE (up to 32,000 µg/L), 1,1-DCE (up to 230 µg/L), 1,1,DCA (up to 320 µg/L), and
vinyl chloride (up to 7,800 µg/L) (Refs 10, 15.
In 2016, Kayser-Roth contractors confirmed the presence of DNAPL in one of the deepest two of
the above monitoring wells (KRLMW-1i). A groundwater sample collected from the monitoring
well in 2016 contained high concentrations of cVOCs including 380,000 milligrams per liter
(mg/L) of PCE, 5,200 mg/L of TCE, 2,900 mg/L of 1,1,1-TCA and 2,700 mg/L of 1,2,4-
trichlorobenzene. Based on well logs and regional information, well KRLMW-1i was screened
into a confining layer (See Groundwater Migration Pathway Section) and was suspected of acting
as a DNAPL “sump”, trapping DNAPL (via gravity) into its lower screened zone (Ref. 25).
The contamination in the confining layer was hypothesized to have been due to downward
migration, or possibly due to introduction during construction of monitoring wells. A 2018
assessment report found the areal extent of the high cVOC concentrations to be primarily limited
to the “footprint” of the former lagoon. Although contamination is present in the two wells
screened in the confining layer, vertical movement appears to be limited. No site-specific
groundwater data are available from the aquifer beneath the surficial aquifer and underlying
confining unit (Ref. 31).

In March 2018, Kayser-Roth contractors conducted an Aggressive Fluid Vapor Recovery (AFVR)
event using monitoring well KRLMW-1i. A solar-powered automated extraction system was
installed in January 2019 and continues to remove DNAPL from the impacted monitoring well.
The extracted DNAPL is pumped to the surface where it is stored in a steel, double walled tank.
After the tank has accumulated approximately 200 gallons, the contents are then transported to an
offsite hazardous waste disposal facility (Ref. 32).
In NC Superfund Section electronic files: The most recent groundwater sample data from the
former wastewater lagoon area date from a November 2019 sampling event. Monitoring well
KRLMW-1i was not resampled during that event due to the presence (and on-going extraction) of
DNAPL from the well. Sampling results indicated that the highest groundwater cVOC
concentrations existed in shallow monitoring wells in direct proximity to the former wastewater
lagoon (Ref. 33).
Due to a minimal number of (non-drinking) water supply and monitoring wells north of I-95, the
horizontal extent of surficial aquifer groundwater contamination, downgradient from the former
wastewater lagoon source, has not been fully delineated. In addition, access to monitoring wells
on the adjacent property, northeast of the lagoon was denied beginning in 2017 (Ref. 33).
Groundwater samples collected from shallow and intermediate monitoring wells (NEMW-1;
NEMW-1i) on the north side of Kenric Road, opposite the former wastewater lagoon, have
contained vinyl chloride (up to 7,920 µg/L), cis-1,2-DCE (up to 5,430 µg/L), 1,1-DCE (up to 22.7
µg/L) and 1,1-dichloroethane (DCA: up to 128 µg/L). In addition, the adjacent drainage ditch
periodically discharges vinyl chloride. These sampling results indicate that the former wastewater
lagoon’s groundwater cVOC plume has likely migrated north-northwest, beyond I-95 (Ref. 33).
Kayser-Roth Manufacturing Facility:
The specific source of the southwestern groundwater contaminant plume has not been identified
but apparently lies beneath the facility structure. The facility plume is migrating to the west and
northwest towards adjacent residential properties. The earliest documentation of contamination at
this source was in March 1999, during a limited soil and groundwater assessment that identified
concentrations of PCE and TCE in groundwater (Refs. 10, 19, 31).
In NC Superfund Section electronic files: The most recent groundwater sample data from the
Kayser Roth manufacturing facility date to November 2019, from shallow monitoring wells
located on the property. The highest groundwater cVOC detections from that event included PCE
(616 µg/L), TCE (36.6 µg/L), cis-1,2-DCE (71.6 µg/L) and vinyl chloride (1.95 µg/L). A shallow
monitoring well (MW-14) located adjacent within the northwest corner of the site property
boundary contained PCE (175 µg/L), TCE (36.6 µg/L) and cis-1,2-DCE (71.6 µg/L) (Refs. 2, 33).

No monitoring wells are present in outside proximity to, or across I-95 from, this location. Both
sets of results exceeded Maximum Contaminant Levels (MCLs) for each of the listed compounds.
Based on the latter result, and the absence of monitoring wells to the northwest, outside the facility
property line, the extent of surficial aquifer groundwater contamination downgradient from the site
property has not been fully delineated (Refs. 2, 33).
Surface Water Sampling:
A 2018 site assessment and workplan amendment report identified a surface drainage ditch located
north of I-95 across from the former wastewater lagoon. The ditch flows west-northwest along I-
95 and then turns north, and drains further to the northwest, into an apparent wetland area near the
Lumber River.
During investigations in 2018 and 2019, Kayser-Roth contractors collected surface water samples
from the ditch. Sample cVOC concentrations were compared to the North Carolina 2B Water
Quality Standards for Class WS (I-V) waterways. A surface water sample (SW-1) collected on
November 27, 2018 exceeded the Class WS (I-V) 2B standard of 0.025 µg/L for vinyl chloride, at
a reported concentration of 130 µg/L. Surface water samples collected on January 18, 2019 from
eight locations along the ditch also exceeded the 2B surface water standards for vinyl chloride
(maximum 46.8 µg/L), with concentrations decreasing downstream (Refs. 31, 32).
Surface water samples collected from the ditch on May 21, 2019 did not exceed of the Class WS
(I-V) 2B standards for any of the compounds analyzed. However, groundwater samples collected
the same day (via passive diffusion bag) from temporary monitoring wells installed adjacent to the
ditch did contain elevated levels of VOCs, including 1,4-dichlorobenzene (15.7 µg/L), 1,1-
dichloroethane (168 µg/L), cis-1,2-DCE (3,890 µg/L), vinyl chloride (6,520 µg/L) and 1,4-dioxane
(91.0 µg/L). All of the results except 1,4-dichlorobenzene exceeded groundwater MCLs (Refs. 2,
32).
Because elevated VOC concentrations had been detected in groundwater and adjacent surface
water, the Kayser-Roth contractor posted a sign warning of the stream and groundwater
contamination. The working hypothesis was that when groundwater baseflow contributed
significantly to surface water flow, VOCs discharging from the wastewater lagoon’s groundwater
contaminant plume caused surface water to exceed standards. The third, most recent workplan
amendment specified that surface water sampling would be conducted twice per year, with plans
to sample when baseflow is the dominant contribution to surface water flow (Ref. 33).

Soil Gas/Indoor Air:
Kayser-Roth Manufacturing Facility:
In January 2017, October 2017, and January 2018, Kayser-Roth contractors conducted sub-slab
soil gas sampling at the facility, installing three permanent vapor “pins” within the facility
structure’s floor slab. During the three sampling events, sub-slab soil gas sample results ranged
up to 4,380 µg/m3 of PCE, 273 µg/m3 of TCE, 284 µg/m3 of 1,1-dichloroethane; 45 µg/m3 of
dichloromethane; 8.4 µg/m3 of toluene; 15.8 µg/m3 of 1,1,1-trichloroethane; and 6.7 µg/m3 of
chloroform (Ref. 31). In November 2018, 16 sub-slab PSG samplers were installed beneath the
facility structure. The sub-slab PSG sample results ranged up to 10,469.91 µg/m3 of PCE, 3,334.43
µg/m3 of TCE, 44.15 µg/m3 of 1,2,4-trichlorobenzene, 12.42 µg/m3 of 1,1-dichloroethane; and
1.28 µg/m3 of vinyl chloride. The results for PCE and TCE exceeded EPA’s Target Sub-slab/Near
Source Vapor Intrusion Screening Levels for commercial use (584 µg/m3 and 29.2 µg/m3,
respectively, based on a HQ of 0.1) (Refs. 32, 36).
In April 2020, a fifth subsurface intrusion study was conducted that included 14 sub-slab PSG
samples and 14 passive indoor air (PIA) samples collected from within the facility. Previous
groundwater sampling results indicated that - in contrast to the groundwater contaminant plume
associated with the former wastewater lagoon - the contaminant plume beneath the manufacturing
facility contained minimal concentrations of transformation products such as dichloroethenes or
vinyl chloride. Therefore, samples collected in 2020 were analyzed only for PCE and TCE (Ref.
33 Figures 9 through 17). Passive sub-slab samples contained up to 141,000 µg/m3 of PCE and
928 µg/m3 of TCE, exceeding the Sub-slab VISL. Passive indoor air samples contained up to 133
µg/m3 of PCE and 17.2 µg/m3 of TCE, exceeding IASLs and RSLs (Refs. 33, 35, 36).
Kayser-Roth contractors commenced voluntary mitigative measures in May 2020, including the
use of indoor air carbon-based APUs and modifications to building ventilation. The contractors
conducted additional indoor air sampling events in May, June and July of 2020 to monitor the
effectiveness of the mitigation measures, and conducted quarterly indoor air sampling thereafter,
reporting results and calculated risk to the NC Superfund IHSB. Following activation of the APUs
in May, air sampling results ranged up to 78 µg/m3 of PCE and 1.4 µg/m3 of TCE. The June and
July 2020 indoor air sample results ranged from 6.1 to 150 µg/m3 of PCE and 0.20 to 1.8 µg/m3 of
TCE, depending on location within the facility, operation of the APUs, and overall air circulation
of the facility. The highest PCE and TCE indoor air concentrations occurred in samples collected
from the middle warehouse section of the building, correlating with high sub-slab soil gas
concentrations in the same area. PCE levels remained above the (35 µg/m3) NIASL and (18 µg/m3)
RSL in multiple samples. (Ref. 33, ).

November 9, 2022
Page 15
During the May and July 2020 indoor air sampling events, PCE and TCE exceeded EPA RSLs for
worker indoor air (18 µg/m3 and 0.88 µg/m3, respectively, based on 0.1 non-cancer hazard
quotient) at multiple sample locations. During shutdown of APUs in June 2020, all of the indoor
air PCE and most TCE results exceeded the RSL. PA evaluation of the results using the EPA’s
Vapor Intrusion Screening Level Calculator indicated that (in May, June and July 2020) the
maximum PCE and TCE concentrations exceeded commercial Target Indoor Air concentrations
(17.5 µg/m3 and 0.876 µg/m3, respectively, based on a Target Carcinogenic Risk of 1E-4 and a
Target Hazard Quotient of 0.1 (Ref. 36).
On May 11, 2022, Kayser-Roth contractors notified DEQ that indoor air concentrations of PCE
and TCE exceeded acceptable levels for non-residential workers based on the NCDEQ risk
calculator tool. Subsequent mitigation efforts were implemented including carbon replacement in
the two air purifying units, relocation of one APU, modifying indoor air circulation and removing
cleaning products containing PCE and/or TCE from the structure. An additional air scrubber was
also rented and deployed for interim use, and in June 2022 two carbon air scrubbers were
purchased for permanent use. Subsequent sampling on June 23, 2022 indicated further reduction
in PCE (maximum 124 µg/m3) and TCE (maximum 2.34 µg/m3) (Ref. 37).
PCE and TCE continued to exceed NIASLs and RSLs. In response, Kayser-Roth initiated plans
to seal floor cracks and to plug potential pathways (e.g., unused floor drains) to further mitigate
subsurface intrusion (Ref. 37).
Outdoor Soil Gas Sampling:
In November 2018 Kayser-Roth contractors conducted a passive soil gas (PSG) survey on and
near the site. The survey used 27 PSG samplers which were installed within the site property
boundary and 29 PSG samplers installed at off-site locations parallel to the right-of-ways of West
5th Street, and Kenric Road. PCE was detected in several of the PSG samples collected from off-
site locations, at maximum concentration of 5.46 µg/m3. TCE and vinyl chloride were not detected
in any off-site samples from the 2018 event (Ref. 32)(see Attachment 1).
Kayser-Roth reported that the above PSG results demonstrated a minimal risk of subsurface vapor
intrusion to inhabited off-site structures. However (as previously noted in the Site Regulatory
History section above) during the November 2018 PSG sampling event, sample boreholes were
drilled to a depth of only 6 inches below ground surface (bgs), due to concerns about underground
utilities along the right-of-ways. In contrast, the vendor’s PSG installation guidance specifies
drilling a 1.5 inch-diameter hole to a depth of 1.0 foot, and a 0.5 inch-diameter hole further
advanced to a depth of 3 feet, with the sorbent sampler suspended by a metal wire at a 1.0-foot
depth within the upper borehole (Ref. 38). The 2018 PSG sampling results therefore may not have
been representative of subsurface conditions.

Groundwater Migration Pathway and Targets:
Hydrogeologic Setting:
The Kayser-Roth Lumberton site is located in the Coastal Plain physiographic province of North
Carolina. The surficial aquifer in this area is composed of medium to coarse-grained sand, sandy
marl, and limestone (Refs. 40, 41). Based upon well logs and field observations documented in
site reports, soils and surface sediments include sandy silty clays, clayey sandy silts, and sandy
silts between the ground surface and 6 to 10 feet bgs. These are underlain by fine to coarse sands
with intermittent clay layers ranging from 1 to 3 feet in thickness, between 6 and 19 feet bgs. Based
on observations from the monitoring reports, the surficial aquifer extends to about 18 feet bgs, on
average. Typical depth to groundwater in the surficial aquifer across the site is less than 10 ft bgs,
with water levels in some wells on the adjacent property east of the lagoon area at depths of
approximately 1-2 ft bgs (Ref. 31).
The surficial aquifer is underlain by the Black Creek Confining Unit (BCCU), which is a part of
the Black Creek Formation. The Black Creek Formation contains a gray to black lignitic clay, with
thin beds of micaceous sand and thick lenses of cross-bedded sand and with glauconitic,
fossiliferous clayey sand lenses in the upper part. Logs from installation of wells greater than 15
feet deep (and other borings) documented in the annual site assessment reports identified the
presence of the BCCU between 17 feet and 24 feet bgs, based on the presence of layers with higher
clay content, including a greenish gray clay of medium plasticity, as well as the presence of small
shell fragments. The BCCU confining unit is interpolated to be approximately 25 feet thick in this
location; neither of the deeper monitoring wells installed at the site (KRLMW-1d, 50 ft bgs and
KRLMW-1dd, 70 ft bgs) extended through the BCCU into the underlying Black Creek Aquifer,
indicating the BCCU is likely continuous across the site (Refs. 31, 40, 41).
Topographic relief across the site is minimal, estimated to be approximately 2 ft with elevations
between 122 and 124 feet above mean sea level (amsl) (Ref. 3). The hydraulic gradient at the site
is also low, according to the numerous groundwater monitoring reports available. In general,
groundwater flow in the surficial aquifer near the former lagoon area appears to be to the north or
northeast, and this is supported by the shape of the contaminant plume and detection of VOC’s in
wells north of I95. In the plant area, local flow direction in the surficial aquifer appears to be
dynamic and difficult to characterize based on water level data; although not completely delineated,
the VOC plume from the plant facility has affected groundwater to the north, south, and west of
the industrial structures. Historic potentiometric maps produced by consultants retained by
Kayser-Roth frequently show apparent mounding and/or depressions in the water-table surface,
and flow direction can be variable. Landscape features such as the drainage ditches along West
5th Street and I-95 corridor, the retention pond south of the plant facility, and the impervious
surfaces all likely influence the underlying water table and affect localized groundwater flow (Refs.
31, 33).

Groundwater Targets:
Municipal water is widely utilized in the area near the site and no private or community drinking
water supply wells were identified within areas known to be contaminated from the groundwater
plumes originating from the Kayser-Roth property. In 2017, at the request of the DEQ, Kayser-
Roth contractors completed an updated well survey. Based upon previous receptor-survey results,
door-to-door property visits, and information provided by Robeson County’s Health Department,
the updated survey identified only one private water well within a 1,500-foot radius of the Kayser-
Roth property. The well, located at a residence at 3919 West 5th Street, was reportedly constructed
to a depth of 14 feet bgs and was used only for irrigation (Ref. 30).
The municipal water supply for the City of Lumberton consists of surface water from the Lumber
River, combined with groundwater from several municipal production wells located along the
Lumber River floodplain. The nearest municipal well to the site is located approximately 1.5 miles
(direct) to the west-southwest and upgradient from the Kayser Roth manufacturing facility. The
nearest downgradient municipal wells are located beginning 2.05 miles (direct) northwest from the
former wastewater lagoon (Ref. 3).
Groundwater Pathway Sample Locations:
No groundwater sampling was conducted as part of the current Preliminary Assessment.
Groundwater Pathway Conclusions:
Two separate cVOC contaminant plumes exist in groundwater at the Kayser-Roth Lumberton site.
One plume originated beneath the manufacturing plant area, and the other originated at the former
wastewater lagoon in the (present) northeastern corner of the property. Both contaminant plumes
have migrated beyond the site property line. However, no private residential drinking water wells
have been identified in proximity to the site, and the nearest municipal groundwater wells are at
considerably greater distance. Based on available information and current site conditions, the
exposure hazard posed by the site’s groundwater migration pathway appears to be minimal.
Surface Water Migration Pathway and Targets:
Hydrologic Setting:
Intermittent drainage ditches exist on the Kayser-Roth property and along the major roadways to
the north. No perennial surface waterways exist on the property. A small stormwater retention
pond remains on the site property, near the southwestern corner of the facility property (Ref. 6).

VOC and 1,4-dioxane contamination has been identified in a small drainage ditch located north
across I-95 from the site’s former wastewater lagoon. Vinyl chloride, other cVOCs and 1,4-
dioxane also have been detected in groundwater samples adjacent to the ditch. Detected vinyl
chloride concentrations in ditch surface water samples decreased in concentration farther
downstream. There is no direct overland flow path from the site to the ditch north of the site and
I-95. It is likely that contaminated groundwater migrates from the area of the former wastewater
lagoon and discharges to the ditch during times of high groundwater elevation, resulting in the
detection of cVOCs and 1,4-dioxane. Due to the contaminant concentrations detected in ditch
surface water and shallow groundwater, Kayser-Roth contractors issued a notice of contamination
and posted a health warning sign has been posted along the ditch, where they reportedly plan to
conduct additional surface water monitoring (Refs. 31, 32, 33).
The drainage ditch is connected to “interconnected pools of surface water” in mapped palustrine
forested wetlands along the Lumber River, the latter of which constitutes the site’s 15-mile surface
water pathway target distance limit (TDL). The section of the Lumber River north of the Kayser-
Roth site is protected for all Class B and C uses including primary contact recreation such as
swimming, diving, and water skiing as well as aquatic life propagation, survival and maintenance
of biological integrity (including fishing and fish), wildlife, secondary contact recreation, and
agriculture (Refs. 6, 31).
Surface Water Targets:
The City of Lumberton obtains drinking water from a surface water intake on the Lumber River.
The intake is located approximately 4.4 river miles downstream (northeast) of the drainage ditch
location. Water from the intake is treated and mixed with groundwater from several municipal
wells along the river course (Refs. 3, 32).
Palustrine wetlands are mapped along the entire Lumber River floodplain within the 15-mile
surface water pathway TDL (Ref. 6). Various rare plant and animal species have been identified
along the river in Robeson County. The Red-cockaded woodpecker (Picoides borealis is a listed
endangered species in river ecosystem. Threatened species along the river in Robeson county
include the Wood stork (Mycteria americana) and the American alligator (Alligator
mississippiensis). The American Bald Eagle (Haliaeetus leucocephalus) is protected under the
Bald and Golden Eagle Protection Act (Refs. 42, 43).
Surface Water Sampling and Results:
No surface water sampling was conducted as part of the current Preliminary Assessment.
Surface Water Pathway Conclusions:
Based on available data on current site conditions, the exposure hazard posed by the site’s surface
water migration pathway is anticipated to be minimal.

Soil Exposure and Subsurface Intrusion Pathways and Targets:
Land use in the vicinity of the Kayser-Roth facility is a mix of commercial, church, industrial,
residential, and agricultural. West 5th Street borders the Kayser-Roth property to the north,
running parallel to I-95/U.S. Route 301 and Kenric Drive. A second, separate textile
manufacturing facility was located northeast, adjacent to the site’s former wastewater
lagoon, but has since been demolished. The Lumberton Regional Airport borders much of
the Kayser-Roth property line to the east and to the south of the site, and an agricultural
parcel owned by the City of Lumberton is located beyond. A mix of commercial, church,
residential and undeveloped properties are located to the north and northwest of the
site. The facility is currently active and employs approximately 118 workers. Access to the
site is partially restricted by a fence. No residents are located on-site; the nearest residence
is located 30 feet northwest of the site property line. No schools or day care facilities operate
in proximity to the site. However, it is not known if the church located at 3733 West 5th Street
operates a school or day care center
(Refs 5, 44).
Soil Exposure Component:
The Kayser-Roth Lumberton property is partially fenced, along property boundaries with the
airport, and with adjacent properties along West 5th Street. The former wastewater lagoon area is
overgrown with dense vegetation. The rear portion of the property is remote, consisting mainly of
loading docks, and is not conducive to trespassing.
Former Wastewater Lagoon:
In 1997, a sludge sample collected from the existing lagoon contained 2,200 mg/kg of TCE and
20,000 mg/kg PCE. The sludge was excavated and transported offsite for hazardous disposal as
part of the lagoon closure in 2003, and the area was backfilled with material from offsite (Ref. 21).
In 1999, shallow soil samples were collected from locations near the wastewater lagoon. One soil
sample, collected adjacent to the lagoon contained a low reported cVOC concentration (7 µg/kg
1,2-DCE) (Ref. 10). No structures are presently located in proximity to the lagoon.
Kayser-Roth Manufacturing Facility:
In 1999, soil samples were collected from outdoor locations at the manufacturing facility and
beneath facility dye trenches. One of the samples from the dye trench contained 6 µg/kg of PCE
and 27 µg/kg DCE, but the other three had no detections of VOCs. Soil samples were also
collected at 5-foot depth intervals during the installation of eight shallow monitoring wells near
the facility in June 1999. PCE was detected in two monitoring well boreholes, located west and
southwest of the facility structure in an asphalt parking lot (Ref. 9).

Based on a review of previous investigations and the lack residents, schools/day cares or
workplaces on an area of shallow soil contamination on site, the hazard posed to human
health via the soil exposure component is anticipated to be minimal.
Subsurface Intrusion Component:
Chlorinated VOCs have been detected in both soil gas and groundwater on site. Subsurface
intrusion (SsI) of cVOCs remains an ongoing issue within the Kayser-Roth manufacturing facility,
due to the groundwater contaminant plume originating beneath the structure’s foundation slab (see
Site Regulatory History and Site Investigative History, above).
In November 2018, 16 sub-slab PSG samplers were installed beneath the facility structure. The
sub-slab PSG sample results ranged up to 10,469.91 µg/m3 of PCE, 3,334.43 µg/m3 of TCE, 44.15
µg/m3 of 1,2,4-trichlorobenzene, 12.42 µg/m3 of 1,1-dichloroethane; and 1.28 µg/m3 of vinyl
chloride. The results for PCE and TCE exceeded EPA’s Target Sub-slab/Near Source Vapor
Intrusion Screening Levels for commercial use (5,840 µg/m3 and 292 µg/m3, respectively for
Hazard Quotient of 1; 584 µg/m3 and 29.2 µg/m3, respectively, for Hazard Quotient of 0.1) (Refs.
32, 36).
On May 11, 2022, Kayser-Roth contractors notified the DEQ IHSB that indoor air concentrations
of PCE and TCE had recently increased, and exceeded acceptable risk levels for non-residential
workers, according to the NCDEQ risk calculator tool. In response, Kayser-Roth contractors
augmented the indoor mitigation efforts by replacing carbon in the two APUs, relocating one APU,
modifying indoor air circulation and removing cleaning products containing PCE and/or TCE from
the structure. An additional air scrubber was also rented and deployed for interim use, and in June
2022 two carbon air scrubbers were purchased for permanent use. Subsequent sampling on June
23, 2022 indicated a reduction in indoor air concentrations of PCE (maximum 124 µg/m3) and
TCE (maximum 2.34 µg/m3). However, PCE and TCE continued to exceed their RSLs (Refs. 35,
37).
In a July 2022 communication with the NC IHSB, Kayser-Roth contractors reported that they were
taking subcontractor bids to seal floor cracks and to plug potential pathways (e.g., unused floor
drains) at the manufacturing facility. Previously, in May, the contractors had noted that they were
considering installation of a sub-slab depressurization system (SSDS) as a long-term remedial
option (Ref. 37).

SsI from migration of the Kayser Roth manufacturing facility’s cVOC groundwater contaminant
plume represents a potential exposure hazard at residences, churches and commercial facilities
located to the north and west of the Kayser-Roth property line. SsI from migration of the second
contaminant plume originating at the former wastewater lagoon could affect commercial properties
located north-northwest to northeast, beyond I-95.
Kayser Roth contractors conducted an extensive on- and off-property soil gas investigation in 2018,
collecting PSG samples at 29 locations along roadway ROW adjacent to the above properties. The
maximum detected PCE concentration of 5.46 µg/m3 did not exceed the EPA’s Target Sub-
Slab/Near-Source VISL of 139 µg/m3. However, the shallow (6-inch) depth of sampler
emplacement did not conform to the vendor’s sampling protocol, and therefore may not have
adequately characterized the exposure hazard (Refs. 32, 37, 38) (see Attachment 1).
Preliminary Assessment Sampling:
The Scope of the current PA consisted of conducting confirmatory PSG sampling at selected
locations northeast, north and northwest of the Kayser-Roth site property. PSG sampling was
conducted using a “Besure” passive soil-gas sampling kit, provided by Beacon Environmental
Services, Inc. PSG samplers were emplaced at nine locations at the six properties to which
sampling access was granted by the property owners. These included four samples on two
properties (3601 and 3733) in direct proximity to the site along West 5th Street, and five samples
on four properties (2055, 2121, 2353 and 2373) to the north along Kenric Road (Ref. 45) (see also
Figure 2 and Appendix A).
PSG samplers were deployed on July 26, 2022 and retrieved on August 10, 2022, after 15 days of
equilibration (Ref. 44). At each soil vapor sampling location, a 1.5 inch-diameter hole was power-
drilled into the ground surface to a depth of 1.0 foot. From the bottom of the borehole, a 0.5 inch-
diameter borehole was further advanced to a total depth of 3 feet bgs. The PSG samplers were
suspended by metal wire into the upper boreholes. Compacted aluminum foil was used to anchor
the upper sampler wires and to seal the upper boreholes from the atmosphere. Following retrieval,
samplers were secured and shipped to Beacon Environmental for VOC analysis (Appendix B).
Beacon analyzed the PSG samples using EPA Method 8260C, for chlorinated and non-chlorinated
volatile organic compounds. A duplicate analysis (KR03SGDup) was performed on downgradient
PSG sampler KR03SG (Appendix B).
PCE was detected at three PSG sample locations (KR03SG and KR03SGDup; KR04SG;
KR08SG). The highest PCE concentration (6.22 µg/m3) occurred in PSG sample KR04SG
collected at 3601 West 5th Street in direct northeast proximity to the former wastewater lagoon.
TCE and 1,1-DCE were also detected in the sample (at 1.9 µg/m3 and 0.98 µg/m3, respectively)
(see Figure 2 and Appendix B).

The other two, lower PCE detections occurred on the west side of the church near the site entrance
(at 3733 West 5th Street) and across I-95 from the former wastewater lagoon (at 2353 Kenric Road).
Another PSG sampler (at 2373 Kenric Road) contained toluene (at 13.1 µg/m3) which was not
attributed to the Kayser-Roth site. No additional VOC detections occurred in the PA PSG samples
(see Figure 2 and Appendix B). None of the PSG results exceeded residential Target Sub-
Slab/Near-Source VISLs (Ref. 36).
Air Migration Pathway
Kayser-Roth Corporation is located in a sparsely populated area in western Lumberton.
Approximately fifteen residences are located within 1000 feet from the site property line, in a
northwesterly to southwesterly direction that is generally up the prevailing wind direction(s)
relative to the site. The 1000-foot radius also includes three church buildings and five businesses
to the north and northwest (Ref. 5). No ambient air sampling is known to have been conducted
around the site perimeter. However, site contaminants are identified primarily in groundwater and
soil gas, and in on-site SsI to the manufacturing facility’s interior. Based on the above information,
the hazard posed by the air migration pathway is considered to be minimal.
Preliminary Assessment Conclusions
The Kayser-Roth Lumberton site was not included on the NC DEQ IHSB’s Site Priority List (SPL)
and had not entered the IHSB’s REC Program as an alternative. Kayser-Roth contractors have
independently conducted indoor air sampling on a quarterly basis, while continuing to conduct
mitigation efforts for the indoor air contamination at the manufacturing facility. Kayser-Roth
contractors have communicated these results and activities to the IHSB on a voluntary basis. Off-
site SsI potential was investigated during the current PA and minimal potential hazard was
identified via that exposure route.
In October 2022, based on the ongoing worker exposure to indoor air contamination, the NC
Superfund Section FRB contacted the Superfund Section IHSB regarding current and future
remedial activities at the site. Following discussion with the IHSB, Kayser-Roth contractors
reported that the company had agreed to sign a REC administrative agreement to address imminent
hazards and long-term remediation of the indoor air contamination with IHSB oversight. These
actions will be conducted in accordance with stipulations outlined in the written REC agreement
and are anticipated to include but are not limited to the installation of a sub-slab depressurization
system and active subsurface source remediation. Kayser-Roth plans to address the former
wastewater lagoon portion of the site under a separate agreement with other potentially responsible
parties.

Based on current site conditions and ongoing negotiation for remediation, future activities at the
Kayser-Roth Lumberton facility will be conducted under the purview of the IHSB. The FRB will
maintain communication with the IHSB regarding the progress of site remediation to ensure that
no further remedial activities under CERCLA are warranted. If you have any questions, please
contact me at [e-mail] or at [phone].

[TOC_1]Case Narrative[TOC]Case Narrative
U.S. EPA Method 8260C
All samples were analyzed using thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS)
instrumentation following U.S. EPA Method 8260C, with laboratory results provided in nanograms (ng) and
micrograms per cubic meter (!g/m‡). Laboratory QA/QC procedures included internal standards, surrogates, and
blanks based on EPA Method 8260C. Analyses and reporting were under BEACON’s Quality Assurance Project Plan.
Passive Soil-Gas Survey Notes
If sample locations are covered with or near the edge of an impervious surface (e.g., asphalt or concrete), the
concentrations of compounds in soil gas are higher than if the surfacing was not present. Therefore, the sample
location conditions should be considered when comparing results between locations.
Survey findings are exclusive to this project and when the spatial relationships are compared with results of other
BEACON Surveys it is necessary to incorporate information from both investigations (e.g., depth to sources, soil types,
porosity, soil moisture, presence of impervious surfacing, sample collection times).
Reporting Limits
The RLs represent a baseline above which results meet laboratory-determined limits of precision and accuracy. All
reported results are within the calibration range. The project method quantitation limit (MQL) is the limit of
quantitation (LOQ) as noted in the data tables. Beacon determined uptake rates for a suite of compounds with the
Beacon sampler for sampling in air. Beacon calculated the uptake rates for the remaining compounds using Grahams
Law of Diffusion. The reported data includes LOQ limits.
Project Details
Samples were received in proper condition and laboratory control parameters were met unless otherwise noted
below. The work performed was in accordance with ISO/IEC 17025:2017, except compounds reported with are
not included in Beacon’s scope of accreditation and samples were analyzed within a 24-hour tune window.
