for the

OLD WILMINGTON ROAD
GROUNDWATER CONTAMINATION SUPERFUND SITE
INTERIM RECORD OF DECISION FOR OPERABLE UNIT 1
WEST CALN TOWNSHIP, CHESTER COUNTY, PENNSYLVANIA

I.	INTRODUCTION

Site Name:	Old Wilmington Road Groundwater Contamination Superfund Site

Site Location:	West Cain Township, Chester County, Pennsylvania

Lead Agency:	U.S. Environmental Protection Agency, Region 3 (EPA)

Support Agency: Pennsylvania Department of Environmental Protection (PADEP)

Statement of Purpose

This Explanation of Significant Differences (ESD) for the Old Wilmington Road Groundwater
Contamination Superfund Site (Site) is being issued in accordance with Section 1 17(c) of the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended
(CERCLA), 42 U.S.C. § 9617(c), and Section 300.435(c)(2)(i) of the National Oil and
Hazardous Substances Pollution Contingency Plan (NCP), 40 C.F.R. § 300.435(c)(2)(i). Both
Section 1 17(c) of CERCL A and Section 300.435(c)(2)(i) of the NCP require the publication of
an ESD when modifications to the remedial action selected in the Record of Decision (ROD) are
necessary, and such modifications significantly change, but do not fundamentally alter the
selected remedy with respect to scope, performance, or cost.

On April 14, 2023, EPA issued an Interim ROD for the Site in which it selected an interim action
for Operable Unit 1 (OU-1) (Selected Remedy). To solicit community input on its proposed
modifications to the Interim ROD, EPA provided a 30-day public comment period on a proposed
ESD (Draft ESD) from September 11, 2023 to October 11, 2023. A notice of availability for
review of the Site documents was published in the Daily Local News on September 11, 2023,
encouraging the public to submit comments on the Draft ESD. In the Draft ESD, EPA proposed
the modifications to the Site remedy for OU-1 summarized below, and the Responsiveness
Summary (Section VII, below) addresses any significant comments received during the comment
period regarding the Selected Remedy, as modified by the proposed modifications.

The Selected Remedy consisted of the following components: a public waterline, vapor intrusion
(VI) mitigation systems, institutional controls (ICs), and long-term monitoring (LTM).

This ESD modifies the OU-1 Selected Remedy by:

-------
• Adding perfluorooctanoic acid (PFOA) and pert!uorooctanesulfoni c acid (PFOS) to the
list of Site-related contaminants of concern (COCs);

• Expanding the proposed waterline in the Selected Remedy to address PFOA and PFOS in
residential wells;

• Establishing applicable or relevant and appropriate requirements (ARARs) and
performance standards' for PFOA and PFOS to determine which residences fall within
the expanded area to be offered connection to the waterline, identified as the Area of
Concern (AOC);

• Updating the estimated costs of the Selected Remedy;

• Modifying ICs to reduce exposure to PFOA and PFOS in groundwater at properties
within the AOC by: 1) deterring the use of untreated groundwater for potable purposes;
2) prohibiting the installation of any new groundwater wells until remediation standards
and protectiveness have been achieved, unless EPA, in consultation with PADEP, gives
prior written approval for such installation; and, 3) prohibiting all activities that would
interfere with any component of the remedial action, unless EP A, in consultation with
PADEP, gives prior written approval for such activity. With this ESD, EPA does not
propose to modify the ICs to address VI risk for PFOA and PFOS because PFOA and
PFOS do not present a known VI risk.

These selected modifications expand the Selected Remedy to address PFOA and PFOS by
extending the geographic extent of the waterline. These modifications arise out of the
investigation of PFOA and PFOS contamination at the Site, as was discussed in the Interim
ROD. See Section II.B. below. These modifications, while significant, do not fundamentally
change the Selected Remedy.

This ESD for the Site summarizes the information that supports these modifications. The
information EPA has relied upon or considered in issuing this ESD has been added to the
Administrative Record file for OU-1 in accordance with Section 40 C.F.R. § 300.825(a)(2) of the
NCP. The Administrative Record file is available for public review at the locations listed below
in Section VI, Public Participation.

II. SUMMARY OF SITE HISTORY. CONTAMINATION, AND SELECTED
REMEDY

A. Background

The Site is located in West Cain Township, Chester County. The Site was placed on the National
Priorities List (NPL) on February 4, 2000. The National Superfund Database Identification
Number is PAD981938939. The Site consists of four investigation areas and three inter-
connected plumes of contaminated groundwater.

The Site investigations areas are as follows:

1 This ESD does not establish cleanup levels for VI (see App E of Interim ROD) for PFOA and PFOS because those
COCs do not present a known VI risk.

-------
• Investigation Area 1 (Area 1) includes a junkyard located on Old Wilmington Road,
across the street from Investigation Area 4.

• Investigation Area 2 (Area 2) is located at the end of Donovan Drive and includes an
inactive former landfill.

• Investigation Area 3 (Area 3) is located right next to Area 1, on Old Wilmington Road,
and includes two stone-filled trenches present on the northwestern edge of the property
where liquid wastes were allegedly disposed.

• Investigation Area 4 (Area 4) is located on the east side of Old Wilmington Road, across
the street from Area 1. This investigation area includes a truck yard which was identified
as a possible source of groundwater contamination.

The three inter-connected plumes of contaminated groundwater consist of the following COCs
(see Attachment 1):

• A plume predominantly consisting of tetrachloroethene (PCE);

• A plume predominantly consisting of trichloroethene (TCE); and

• A plume predominantly consisting of 1,4-Dioxane.

Various inorganic COCs are also present at the Site.

For management of the remedial action, EPA has organized the Site cleanup into two OUs:

• OU-1 is defined by the contaminated groundwater used as drinking water and volatile
organic compound (VOC)-contaminated vapors attributable to the Site-related
groundwater plumes with the potential to migrate from subsurface into residential indoor
air.

• OU-2 is defined by the remaining Site-related contamination in soils and groundwater.

-------
B. History of Contain illation

The Site has been the subject of numerous past investigations as a result of multiple complaints
of waste disposal that were investigated by the Chester County Health Department (CCHD) and
the Commonwealth of Pennsylvania (Pennsylvania or PA) during the 1970s and 1980s. Records
indicate that a waste disposal permit was never applied for, while eyewitness accounts
additionally reported that tanker trucks were observed discharging their contents onto the ground
adjacent to the landfill, among other areas. Aerial photographs show mounded material on the
landfill sometime between 1975 and 1980. Area 2 subsequently became the subject of a
Pennsylvania Department of Environmental Resources (PADER), now known as PADEP,
preliminary assessment in December 1986. In 1988, 1 1 residential wells were sampled by EPA
as part of a Site Investigation (referred to hereafter as 1988 Phillips Landfill SI).

Residential well sampling data collected during the 1988 Phillips Landfill SI indicated that the
residential well located on the junkyard site (Area 1) and several other nearby wells, including
the well system that provides drinking water to the residents of the mobile home park, were
contaminated with TCE and PCE, both of which are VOCs, at concentrations exceeding their
respective maximum contaminant levels (MCLs).

Subsequent sampling conducted by PADEP confirmed the presence of VOC contamination in
the public water supply system for the mobile home park which was subsequently determined to
be impacted by Area 1. In November 1992, sampling and inspection of the public water supply
system for the mobile home park was conducted. Laboratory results indicated that the mobile
home park supply well and a nearby residential well contained VOCs above applicable MCLs,
and the concentration of PCE in the residential well exceeded the EPA removal action level.

EPA initiated a removal site assessment on February 26, 1993. Based on the results of this
assessment, EPA determined that there was an immediate and significant threat to human health
due to elevated concentrations of hazardous substances, including PCE and TCE, in the drinking
water supplies of nearby residents. On December 21, 1993, EPA commenced a removal action,
which focused on providing bottled water, and later carbon filtration units, to residences affected
by groundwater contamination above MCLs.

In 1993, EPA also issued an emergency order to the owner/operator of the mobile home park
under the Safe Drinking Water Act, requiring, among other things, that the owner/operator
provide free bottled water to the mobile home park residents until a drinking water treatment
system and other necessary improvements to the park's water system were installed. In 1996
Perry and Jeanne Phillips, doing business as Phillips Mobile Home Park, entered into a Partial
Consent Decree (1996 Decree) with the U.S. and PADEP, requiring construction of various
water treatment system improvements for the park's residential water supply as well as
delineated sampling and reporting requirements.

As part of the ongoing removal action, EPA also began investigating the source of the
groundwater contamination. Laboratory analytical results from soil gas, soil, and groundwater

-------
sampling indicated that an additional and separate source of VOC contamination existed in Area
3. Those results confirmed eyewitness reports of separate waste dumping in Area 3 and
prompted EPA to identify the area as a potential hazardous waste site on March 11, 1994. Based
on these results, EPA investigated Area 3 separately, which confirmed that two distinct types of
groundwater contaminants were present in separate plumes.

On May 4, 1994, EPA approved a request for additional funding to mitigate potential risks posed
to residents via ingestion of groundwater contamination and inhalation of vapors emanating from
the areas adjacent to Investigation Area 1. The May 1994 approval provided for continued
response actions initiated during the ongoing removal activities at the Site, including providing
whole-house water treatment units to residents with VOC contamination above removal action
levels; determining the area of origin of the VOC contamination in order to mitigate the source
and characterize the plumes; and providing for continued monitoring and maintenance of whole-
house water treatment units to ensure safe drinking water.

After EPA added the Site to the NPL in 2000, EPA initiated Remedial Investigation (RI)
activities that consisted of: (1) Hydrogeologic Investigation, (2) Source Area Assessment, (3)
Surface Water/Sediment Assessment, and (4) Ecological Characterization. EPA prepared an RI
report (2010 RI) in 2010. Subsequent review of the 2010 RI report indicated significant data
gaps, primarily caused by analysis of only a limited well network due to limited Site access. As a
result, in order to further study groundwater contamination at the Site, EPA initiated the
Supplemental RI, which was completed in 2022. This supplemental RI included performing a
baseline round of sampling of all historic wells and stream sampling locations, installation of
new wells at the Site, additional rounds of groundwater sampling, a Site-wide residential
sampling event, and a VI sampling event at homes overlying the plumes. The supplemental RI
found that the groundwater is also contaminated with 1,4-Dioxane, a semi volatile organic
compound (SVOC); elevated concentrations of metals were found at sporadic locations not
impacted by VOC contamination; VOC contamination is present at all four investigation areas;
and sub-slab soil gas detections of Site-related substances at several residences indicated possible
volatilization of contaminants from groundwater. In summary, the Supplemental RI concluded
that groundwater contamination at the Site presents unacceptable risks to drinking water supplies
and subsurface vapors that may affect residential indoor air.

In 2022, EPA developed a Focused Feasibility Study (FFS) to evaluate remedial alternatives for
OU-1. The Preferred Alternative was proposed in a September 2022 Proposed Remedial Action
Plan (Proposed Plan). EPA issued the Interim ROD for OU-1 on April 14, 2023 describing the
Selected Remedy. As noted in the Interim ROD, during the public comment period for the
Proposed Plan, EPA obtained new monitoring well and residential well data on per- and
polyfluoroalkyl substances (PFAS) at the Site. The Interim ROD further noted that EPA would
continue to investigate PFAS contamination at the Site and would address PFAS in a future
decision document. On September 11, 2023, EPA issued a Draft ESD to address PFAS
(specifically, PFOA and PFOS) contamination which proposed the modifications to the Selected
Remedy, which are now being selected in this ESD, after soliciting public comment on the
proposed remedy changes.

-------
PFAS Sampling

February 2021 Sampling Event

On February 16, 2021, PADEP made EPA aware that its State Safe Drinking Water Program
performed PFAS sampling on the supply well servicing the on site mobile home park and found
concentrations of PFO A at 29.3 nanograms per liter (ng/L) or parts per trillion (ppt) and PFOS at
a concentration of 26.1 ng/L in the supply well (see Appendix A).

July 2021 Sampling Event

In July 2021, EPA performed PFAS sampling at a select number of shallow monitoring wells to
confirm the presence of PFAS at the Site. There were detections of PFAS, including PFOA and
PFOS, in eleven monitoring wells (see Appendix B). Higher PFOA and PFOS concentrations
were generally located in the Area 2 (Landfill) investigation area (see Figure 1). EPA reviewed
the PFAS sampling data and concluded that the results for PFOA and PFOS above or near the
2016 Health Advisory Level (HAL) of 70 ng/L, the screening level at the time, represented
levels of concern and recommended that residential wells in proximity to the Site, especially
those downgradient of wells with elevated levels, should be sampled for PFAS.

August 2022 Sampling Event

In August 2022, EPA conducted a second PFAS sampling event. This included three monitoring
wells as well as five residential drinking water wells generally south of Area 2, in the Karen
Circle area. PFOA was detected in two monitoring wells (MW-14 and MW-18) in exceedance
of tapwater Regional Screening Levels (RSLs) of 6 ng/L (Hazard Quotient (HQ) of 0.1) and
PFOS was detected in one monitoring well (MW-14) in exceedance of tapwater RSL of 4 ng/L.
Three other PFAS compounds were detected in monitoring wells but did not exceed screening
levels. See Appendix C.

In the residential wells sampled in August 2022:

• PFOA detections ranged from 10.5 ng/L to 67.2 ng/L and at that time were compared to
the EPA Residential tapwater RSL of 6 ng/L based on HQ of 0.1.

• PFOS detections ranged from 17.8 ng/L to 136 ng/L and at that time were compared to
the EPA Residential tapwater RSL of 4 ng/L based on HQ of 0.1.

• PFOS detections in one residential well (121 ng/L and 136 ng/L) also exceeded the
Removal Management Level (RML) of 120 ng/L based on the HQ of 3.

In November 2022, based on the August 2022 data, at the request of EPA, PADEP provided
bottled water to the residence of RW-185. In February 2023, EPA conducted a removal response
action and, as part of that action, installed a carbon filtration system at the residence of RW-185,
to treat the residential drinking water for PFOS. PADEP ceased delivery of bottled water in May
2023, when sample results revealed that the filtration system was removing PFOS from the
drinking water supply.

February/March 2023 Sampling Event

-------
In February and March 2023, EPA conducted a large-scale PFAS sampling event at the Site.

This included sampling 16 monitoring wells and 33 residential drinking water wells across the
Site, with a focus on residential wells located south of Area 2 (Landfill) on Karen Circle.

Twenty-one groundwater samples (including two duplicates) were collected and analyzed from
the following monitoring wells located throughout the Site: MW-1, MW-3, MW-4, MW-5,
MW-6, MW-8S, MW-11D, MW-12S, MW-13, MW-14 (Ports 1 and 2), MW-15, MW-18 (Ports
1 through 3), MW-19, MW-20, MW-21, and MW-23 (Port 1). Monitoring well MW-10S was
dry upon inspection and could not be sampled.

• PFOS was detected at 12 of the monitoring wells at a maximum detected concentration of
65 ng/L (MW-18 Port 3). Seven of the monitoring wells had concentrations of PFOS that
exceeded 4 ng/L, the EPA Residential tapwater RSL based on a HQ of 0.1; three of
which exceeded the PA MCL of 18 ng/L.2

• PFOA was detected at 12 of the monitoring wells at a maximum detected concentration
of 66 ng/L (MW-13). Eight of the monitoring wells had concentrations of PFOA that
exceeded 6 ng/L, the EPA Residential tapwater RSL based on a HQ of 0.1; five of which
exceeded the PA MCL of 14 ng/L.

Forty-four drinking water samples (including four duplicates) were collected and analyzed from
thirty-three residential wells located throughout the Site.

• PFOS was detected at 23 of the residential wells at a maximum detected concentration of
99 ng/L (RW-217, pre-treated). Nine of the residential wells had concentrations of PFOS
that exceeded 4 ng/L, the EPA tapwater Residential tapwater RSL based on a HQ of 0.1;
three of which exceeded the PA MCL of 18 ng/L.

• PFOA was detected at 25 of the residential wells at a maximum detected concentration of
37 ng/L (RW-217, pre-treated). Ten of the monitoring wells had concentrations of PFOA
that exceeded 6 ng/L, the EPA Residential tapwater RSL based on a HQ of 0.1; three of
which exceeded the PA MCL of 14 ng/L. Bottled water is being provided to these three
homes and will continue to be provided, as warranted, as part of the Selected Remedy, as
modified by this ESD.

The current estimated lateral extent of PFOA and PFOS contamination is shown in Figure 2.
Appendix A contains the analytical results from PADEP's sampling event in February 2021.
Appendix B contains the analytical results from the EPA July 2021 sampling event. Appendix C
contains the analytical results from the EPA August 2022 sampling event. Appendix D shows
sampling locations from both EPA's July 2021 and August 2022 sampling events. Appendix E
contains the sampling locations and maps from EPA's February/March 2023 sampling event and
Appendix F shows the analytical results from EPA's February/March 2023 sampling event.
Additional sampling will be conducted prior to the completion of remedial action for OU-1 and.

2 There is no Federal MCL for PFOS or PFOA. Pennsylvania promulgated an MCL for PFOA and PFOS that
became effective on January 14, 2023. Under Pennsylvania's Act 2, 35 P S. § 6026.101 et seq.. MCLs promulgated
by EPA or P ADEP arc effective immediately for use as medium-specific concentrations for groundwater
remediation in Pennsylvania.

D. Interim ROD Selected Remedy

EPA issued the Interim ROD for OU-1 on April 14, 2023. The Selected Remedy for OU-1
addressed exposure to Site-related groundwater contamination in residential drinking water wells
as well as VI at affected or potentially affected properties. EPA has delineated the extent of the
PCE, TCE and 1,4-Dioxane plumes and identified an AOC which includes properties impacted
or potentially impacted by Site-related COCs. The AOC comprises the area overlying the
groundwater plumes and investigation areas as well as a buffer area around the plumes. The
extent of the buffer area will be determined during the remedial design and will be informed by
the PFAS sampling results. A future decision document will address remaining contamination
present in soils and groundwater at the Site for both OU-1 and OU-2.

The Selected Remedy for OU-1 consisted of a public water line, VI mitigation systems, ICs, and
LTM. The estimated present value of total costs over a 30-year period for the Selected Remedy
is $7,786,000.

Remedial Action Objectives (RAOs) are specific goals developed to address the Site COCs and
exposure pathways to protect human health and the environment. These objectives are based on

-------
available information and standards, such as ARARs, to-be-considered (TBC) materials, and
Site-specific risk-based levels.

The RAO established for drinking water:

•	Prevent potential human exposure to Site-related contaminants in groundwater through
ingestion above levels that pose an unacceptable risk for residential use.

The RAOs established for soil vapor and indoor air:

•	Protect current and future residents from adverse health effects that may result from
exposure to VOC-contaminated vapors attributable to the Site-related groundwater
plumes.

•	Mitigate potential contaminant migration from subsurface VI into residential indoor air.

III. DESCRIPTION OF MODIFICATIONS TO SELECTED REMEDY A NO THF
BASIS FOR SUCH MODIFICATIONS

Based on PFOA and PFOS sampling results at the Site, this ESD modifies the Selected Remedy
for OU-1 with the following':

•	Adding PFOA and PFOS to the list of Site-related COCs that are identified in Appendix
D of the Interim ROD for OU-1;

•	Expanding the proposed waterline route of the Selected Remedy to address residential
wells impacted by PFOA and PFOS;

•	Establishing ARARs and performance standards for PFOA and PFOS to determine which
residences fall within the expanded AOC to be offered connection to the waterline;

•	Updating the costs of the Selected Remedy; and

•	Modifying ICs to prevent exposure to PFOA and PFOS in groundwater at properties
within the AOC by: 1) deterring the use of untreated groundwater for potable purposes;
2) prohibiting the installation of any new groundwater wells until remediation standards
and protectiveness have been achieved, unless EPA, in consultation with PADEP, gives
prior written approval for such installation; and, 3) prohibiting all activities that would
interfere with any component of the remedial action, unless EP A, in consultation with
PADEP, gives prior written approval for such activity. Due to no known VI risk from
PFOA and PFOS, ICs for VI exposure do not pertain to these COCs.

A. PFOA and PFOS Present ail Imminent and Substantial Endangerment to the
Public Health or Welfare

PFAS sampling at the Site to date, discussed above, indicates that the lateral extent of PFOA
and PFOS contamination in groundwater is widespread throughout the Site (see Appendix E).
In one area of the Site, PFO A and PFOS contamination was found at concentrations that
present an imminent and substantial endangerment to the public health or welfare.

3 The Selected Remedy, as modified by this ESD, includes maintaining short-term interim measures, including
maintenance of POETS and provision of bottled water, as appropriate, until a waterline is constructed, operational,
and functional. See Responsiveness Summary at VILA.

-------
PFAS are a group of manufactured chemicals, which includes PFOA and PFOS, that have
been used in industry and consumer products since the 1940s. There are thousands of
different PF AS, some of which have been more widely used and studied than others. PF AS are
considered "emerging contaminants" because research is ongoing to better understand the
potential impacts PFAS compounds pose to human and animal health and the environment.

PFOA and PFOS were found at concentrations exceeding the PA MCL for PFOA and PFOS
south of the Site's AOC, as delineated in the Interim ROD for OU-1. In this area, which is
located around Karen Circle (see maps in Appendix E), four homes exceeded PA's MCLs for
PFOA and PFOS. One home had PFOS levels in well water exceeding the RML of 120 ng/L
and EPA provided a point-of-entry treatment (POET) system for that home during the
February 2023 removal action. In the remaining three residential wells, the maximum
detected concentration of PFOS was 99 ng/L (RW-217, pre-treated). The maximum detected
concentration of PFOA in well water at these homes was 37 ng/L (RW-217, pre-treated).

These concentrations result in unacceptable risk to current residents and exceed the PA MCL
of 14 ng/L for PFOA and 18 ng/L for PFOS. The PFOS concentration in one residential well
exceeded the RML of 120 ng/L indicating an imminent and substantial endangerment, with
other residential wells indicating an unacceptable risk from exposure to PFOA and PFOS
through potable use of residential well water. In addition, consistent with EPA guidance, an
exceedance of MCLs, may be used to determine whether remedial action is warranted. While
PFAS compounds have not yet been designated as hazardous substances under CERCLA,

PFOA and PFOS are pollutants and contaminants, and EPA has the authority to respond to a
release of a pollutant or contaminant that present an "imminent and substantial danger to the
public health or welfare."

B. Establishing ARARs for PFOA and PFOS

As discussed in detail in the Interim ROD for OU-1, Section 121(d) of CERCL A, 42 U.S.C.
§ 9621(d), and the NCP at 40 C.F.R. § 300.430(f)(l)(ii)(B), require that remedial actions at
CERCLA sites at least attain legally applicable or relevant and appropriate Federal and State
requirements, standards of control, and other substantive environmental protection requirements,
criteria, or limitations promulgated under Federal or State law, which are collectively referred to
as "ARARs," unless such ARARs are waived under Section 121(d)(4) of CERCLA, 42 U.S.C. §
9621(d)(4), and the NCP at 40 C.F.R. § 300.430(f)(l)(ii)(C).

ARARs for remedial action alternatives can be classified into one of the following three
functional groups: chemical-specific (which are health-risk-based numerical values or
methodologies that establish concentration or discharge limits for particular contaminants);
location-specific (requirements that restrict remedial actions based on the characteristics of the
Site or its immediate environment); and action-specific (requirements that set controls or
restrictions on the design, implementation, and performance levels, including discharge limits, of
activities related to the management of hazardous substances, pollutants, or contaminants).
Federal and more stringent State chemical-specific ARARs are presented in Appendix C of the
Interim ROD for OU-1. In addition, remedial activities for the Selected Remedy would be
designed to comply with location-specific and action-specific.

-------
The Interim ROD for OU-1 identified Federal MCLs and Pennsylvania groundwater mediutn-
specific concentrations (MSCs) as chemical-specific ARARs for the limited purpose of
determining the scope of the AOC - that is, which residences are impacted, or potentially
impacted, by Site-related groundwater contamination, and as a result will be offered
connection to the waterline.

On January 14, 2023, Pennsylvania promulgated an MCL of 14 ng/L for PFOA and 18 ng/L
for PFOS which became effective upon their publication in the Pennsylvania Bulletin on that
date. Pursuant to Pennsylvania's Land Recycling Program Regulations, 25 Pa. Code 250.1 et
set]., MCLs promulgated by EPA or PADEP are effective immediately for use as MSCs for
demonstrating attainment after groundwater remediation.

Consistent with the Interim ROD, in the absence of promulgated Federal MCLs for PFOA and
PFOS, EPA is selecting in this ESD the PA MCLs for PFOA and PFOS, 25 Pa. Code §
109.202(a)(4)(ii), and promulgated under the Pennsylvania Safe Drinking Water Act, 35 P S. §§
721.1 et set]., as chemical-specific ARARs for those COCs. The PA MCLs for PFOA and PFOS
are relevant and appropriate requirements for the purpose of determining the scope of the AOC
for the waterline connections. This addition modifies Appendix C, Table C-l (Chemical-
Specific ARARs), of the Interim ROD.

As with federal MCLs, the PA MCLs are enforceable standards for public water supply systems
having at least 15 service connections or being used by at least 25 individuals. While not
applicable, the PA MCLs are relevant and appropriate as in situ cleanup standards for
groundwater that is or may be used for drinking water. EPA is not selecting a remedy to clean-up
groundwater on the Site with this interim action, however, PA American Water, a Pennsylvania
off-site public water system, is still required to meet all applicable Pennsylvania Safe Drinking
Water Act requirements, including treatment of drinking water to MCL standards. While PA
MCLs for PFOA and PFOS are not ARARs for such off-Site treatment, they are chemical-
specific ARARs for the purpose of determining which residents will be offered connection to the
newly constructed waterline in connection with the modified remedy.

In addition, the remedial activities in this ESD will be designed to comply with location-
specific and action-specific ARARs identified in the Interim ROD.

C. Modifying Performance Standards and Estimated AOC/ Waterline Route

As indicated in the Interim ROD for OlJ-1, the NCP requires, as threshold criteria, that EPA
select a remedy that is both protective of human health and the environment and compliant with
ARARs. The PA MCLs of 14 ng/L for PFOA and 18 ng/L for PFOS are selected as performance
standards for this modified remedy. These performance standards are contaminant concentration
levels that will be used during remedial design, among other criteria, to delineate the AOC (see
Table 1). Table 1 modifies Appendix D (Performance Standards for Residential Well Water) of
the Interim ROD for OU-1.

This ESD expands the AOC identified in the Interim ROD to encompass approximately 30
additional properties that are, or may be impacted, by PFOA and PFOS contamination, and were
not originally selected to be offered a waterline connection in the Interim ROD for OU-1. This
expansion will result in a total of approximately 90 properties that are, or may be impacted, by
Site-related contamination, and therefore included in the AOC for purposes of connection to the
waterline. See Figure 3 below, which modifies Figure 3 in the Interim ROD for OU-1.
Additional sampling will be conducted prior to the completion of remedial action for OU-1, and,
if necessary, during supplemental remedial investigations related to OU-1 and/or OlJ-2, to
determine the full extent of properties to be offered connection to the waterline.

The total estimated length of the expanded waterline would be approximately 25,505 feet, an
expansion of approximately 9,000 feet from the original waterline selected in the Interim ROD
for OU-1 (see Figure 3 or Appendix H). Specifically, the Draft ESD proposed an expansion of
approximately 6,000 feet, while this final ESD adds an additional 2,985 feet bringing the total to
about 9,000 feet. The total number of properties and the total length of the waterline may be
further refined during remedial design. The Selected Remedy for OU-1, as modified by this
ESD, will continue to be protective of human health and the environment and comply with
ARARs.

welfare.

VI. PUBLIC PARTICIPATION

In accordance with Section 1 17(d) of CERCLA and Section 300.435(c)(2)(i)(B) of the NCP,
EPA published a notice of availability of the Draft ESD on September 11, 2023. EPA relies on
public input so that the remedy selected for each Superfund site meets the needs and concerns of
the local community. To assure that the community's concerns were being addressed, a public
comment period on the Draft ESD opened on September 11, 2023 and closed on October 11,
2023. Additionally, EPA held a Public Information Session on October 3, 2023 at the
Wagontown Fire Company located in Coatesville, PA, during which time EPA presented
information and answered questions about the Draft ESD and the Site cleanup. During the
comment period, EPA received a variety of comments and questions, including those raised
at the public meeting. Responses to significant comments received during the public
comment period can be found in the Responsiveness Summary included in this ESD in Section

The ESD is being incorporated into the Administrative Record file maintained for the Site. The
Administrative Record file includes the documents that form the basis for EPA's Selected

VII. RESPONSIV ENESS SUMMARY

A.	Introduction

EPA has prepared a Responsiveness Summary for this ESD which summarizes the questions and
general concerns received from the public during the comment period regarding both the changes
proposed in the Draft ESD and the Old Wilmington Road Groundwater Superfund Site in
general.

EPA issued a public notice in the Daily Local News on September 11,2023, which contained a list
of the changes proposed by the Draft ESD, information relevant to the duration of the public
comment period, the date of the public meeting, and the availability of the Draft ESD and the AR
file. The public comment period for the Draft ESD was from September 11, 2023 through
October 11, 2023. During the public comment period, EPA received written and oral comments.
Additionally, a public meeting was held on October 3, 2023 at the Wagontown Fire Company,
during which time the public could provide oral comments and ask questions in-person.

After receiving the public's questions and comments both during the public comment period and
at the public meeting for the Site, EPA determined that no significant changes to the proposed
modifications to the Selected Remedy, as presented in the Draft ESD, were necessary or
appropriate. However, in response to some comments received, EPA is clarifying in this ESD
that short-term interim measures, such as bottled drinking water and Point-of-Entry Treatment
Systems (POETS) will continue to be provided to residents at the Site for whom concentrations
of COCs in well water presents a short-term risk to human health. These short-term interim
measures will be maintained until a waterline is constructed, operational, and functional.

B.	Comments Received during Public Comment Period

Three local residents submitted comments to EPA, one comment was emailed and two were left
by voicemail. Additionally, numerous comments and questions were provided orally during the
public meeting on October 3, 2023. A transcript of the public meeting can be found in the AR
file for this Site, which is available to the public online at

https://semspub.epa.eov/src/collection/03 \Ro7-lo ». Below are comments and questions
provided by the public to EPA and EPA's responses to these comments and questions.

Comment #1

Comment: Multiple members of the public asked when the waterline work will start and
if their wells will be sampled again prior to the work being completed.

Response: EP A estimates that the construction of the waterline will begin between April
2025 and April 2026, approximately two to three years from issuance of the April 2023
Interim ROD. After the Interim ROD was issued, EPA began the design phase for the
waterline and is currently developing a plan for its construction. During the design and
construction phases, the EPA-installed POETS will continue to be maintained and

15

-------
monitored by EPA and bottled water will be provided to homes in the Karen Circle Area
with PFOA and PFOS levels exceeding Pennsylvania MCLs. Other residential wells may
be sampled as part of the on-going investigations into OU-1 and OU-2. It is estimated
that actual construction of the waterline will take a total of two to three months from start
to finish, followed by an additional period of restoration work on roads and residential
properties, lasting for approximately two months.

Comment #2

Comment: Members of the public asked about what costs will be covered by EP A and
whether costs for the lateral connection into their home will be covered by EPA.

Response: EP A will pay for construction of the new public waterline main and the lateral
connections to residences within the AOC, where owners have opted-in to receive the
connection by the completion of EPA" s outreach effort (estimated to be completed by
January 2024). Additionally, if a resident chooses to connect to the new public waterline,
EPA will disconnect their indoor plumbing from their residential well and pay for
abandonment of the well, unless a resident chooses to keep their well for non-potable
purposes. However, the monthly water bill and any maintenance required for the lateral,
once the residence is connected, will be the responsibility of the homeowner.

Additionally, if a homeowner chooses not to connect to the waterline and the residence
currently has a POETS installed by EPA, EPA will not continue to monitor and maintain
the POETS after construction of the waterline is completed. Existing POETS for those
choosing to connect to the waterline will be monitored and maintained until connection to
the newly constructed public waterline is completed. Similarly, if a homeowner is
currently being provided with bottled water, once construction of the waterline is
completed and affected homes are connected to the waterline, bottled water will no
longer be provided.

Comment #3

Comment: During the public meeting, a resident asked if one does not connect to the
waterline while it is being constructed but decided later that they wanted to connect, what
would be the cost9

Response: Those who do not accept the connection to the public waterline by the
completion of EPA" s outreach effort and later decide they want to be connected, will
have to pay for the connection themselves. Since the cost of a single private connection
may differ from the costs incurred when there are multiple connections at once, EPA
does not have an estimate for the cost of a private connection. Any such homeowner can
contact Pennsylvania American Water (PAW) to inquire about a private connection and
its cost.

Comment #4

16

-------
Comment: One resident stated: "I was involved in the last water test back in the winter.
[Are] we going to see any results from that anytime soon9

Response: EPA provided homeowners with their sampling results via letters in June
2023. If a homeowner did not receive a letter with their sampling results, EPA will re-
send the results to those homeowners, upon request.

Comment #5

Comment: During the public meeting, an attendee inquired about whether the PAW
information provided by EPA was current.

Response: The information EPA provided regarding PAW's 2023 residential water rates
during the public meeting is current. PAW has a monthly service charge and a water
usage rate. For 2023, the service charge is $17.50 per month, and the residential water
usage rate is $1.61 per 100 gallons. This information can be found on PAW's website
www.amwater.com/paaw/customer-service-billing/vour-water-and-wastewater-rates. A
resident's total monthly water bill will depend on the household's usage.

Comment #6

Comment: During the public meeting, one attendee stated: "I worked in the
environmental industry. PFOA and PFOS - what's the MDL, the maximum detection
level, and what's the maximum level you've seen in the wells in Karen Circle9"

Response: The Method Detection Limit (MDL) is a statistical measure of the lowest
concentration of a substance that can be reliably detected by a given analytical method.
The MDLs for PFOA and PFOS were approximately 9 nanograms per liter (ng/L), close
to EPA's risk screening numbers. For context, EPA's Regional Screening Level (RSL)
based on a hazard quotient of 0.1 for PFOA is 6 ng/L and for PFOS is 4 ng/L. These
levels are below the Pennsylvania Maximum Contaminant Levels (MCLs), which are 14
ng/L for PFOA and 18 ng/L for PFOS.

The maximum detected concentration in residential wells for PFOA was 67 ng/L and 136
ng/L for PFOS.

Comment #7

Comment: During the public meeting, one attendee asked about the route of exposure
for per- and polyfluoroalkyl substances: "Is it ingestion only, ingestion and inhalation, or
ingestion, inhalation and some other route9"

Response: The toxicity data that EPA has currently developed indicates that ingestion is
the primary route of exposure to PFAS. As for the inhalation route of exposure, EPA is
still learning about the ability of PFAS to volatilize. There is some data that shows PFAS
may volatilize out of water, but EP A, and the larger scientific community, are still
working to determine the health risks associated with PFAS volatilization. For more

17

-------
information on potential exposure to PFAS please refer to this link:
https://www.atsdr.cdc.gov/pfas/health-effects/exposure.html.

Comment #8

Comment: A question was raised about whether it's safe to shower with water from the
waterline versus well water.

Response: With regards to the water from the waterline, showering is safe. The water
from the waterline supplied by PAW must meet MCLs, as required by the Safe Drinking
Water Act. Additionally, see response to Comment #27. With regards to well water, see
response to Comment #7.

Comment #9

Comment: Multiple questions were raised regarding the proposed route of the waterline
main extension.

Response: A map of the current estimated waterline route is shown in both Figure 3 of
the ESD and Appendix H of the ESD.

Comment #10

Comment: What size is the waterline9

Response: The size of the waterline will depend on how many houses will ultimately be
connected, but the water main will be a minimum of six inches in diameter. The exact
dimensions will be determined during the design process.

Comment #11

Comment: What would happen if the Site COC groundwater plumes expand9

Response: Current data demonstrate that the volatile organic compounds and 1,4-dioxane
plumes are stable and not expanding. EPA continues to conduct groundwater monitoring
at the Site. However, if future groundwater monitoring shows that the contaminant
plumes are migrating, EPA will conduct additional groundwater sampling as necessary.
With respect to PFOA/PFOS, EPA will continue data collection to inform the remedial
investigation for OU-2. These data will ultimately support a decision to select a remedy
for groundwater cleanup.

Comment #12

Comment: There were questions during the public meeting concerning the current status
of the Site's cleanup and why it has taken so long to do.

Response: Remedial investigations can take years to conduct, given their complexity.
Superfund Sites are typically complex and challenging to clean up and EPA must have

18

-------
enough information in order to make decisions on a cleanup strategy. As stated in the
Interim ROD, EPA continues to investigate contaminated media, including soil and
groundwater, as part of OU-2, at the Site. It is EPA's priority to protect public health and
the environment, and the Selected Remedy provides a permanent public water supply via
a waterline that will prevent exposure to Site-related groundwater contamination in
residential drinking water wells as well as VI while EPA addresses OlJ-2. Once EPA
collects sufficient data and evaluates the data, EPA will identify the clean-up alternatives
for OlJ-2 and will proceed through the community involvement process to present EPA's
preferred alternative for remediation of Site soils and groundwater to the public. While
the investigation for OlJ-2 continues, EPA's priority has been to ensure that the
community's drinking water is safe by first providing POETS to affected residents
through ongoing removal actions, continuing short-term interim measures such as bottled
water, and now by selecting a permanent public water supply via a water line under OU-
1.

Comment #13

Comment: During the public meeting, on resident asked: "Has anybody ever done a
study about how many people have died in [these] two small communities of cancer9"

Response: EPA does not conduct cancer impact studies. Cancer studies are conducted
by the appropriate health agency. While EPA does not conduct cancer impact studies,
EPA does coordinate with the appropriate health agencies that do conduct these studies.
In this case, EPA coordinated with the Agency for Toxic Substances and Disease
Registry ( ATSDR) and the Pennsylvania Department of Health (PADOH). PADOH's
Pennsylvania Cancer Registry is a statewide data system responsible for collecting
information on all new cases of cancer diagnosed or treated in Pennsylvania. The web
address is:

https://www.health.pa.gov/topics/disease/Cancer/Pages/Cancer.aspx. PADOH's Registry
is part of the National Program of Cancer Registries administered by the Centers for
Disease Control and Prevention (CDC). On a county level, out of 67 counties in
Pennsylvania, 5 1 counties have higher cancer incidence rates than Chester County,
meaning that Chester County has one of the lower rates of cancer in Pennsylvania. More

Comment #14

Comment: During the public meeting, several residents asked if Wendy Circle is being
included as part of the waterline extension and if sampling will be done there.

Response: Currently, the new public waterline is not being extended to Wendy Circle.
However, the investigation into both 0U-1 and OlJ-2 continues and EPA will install
monitoring wells in the Wendy Circle area and potentially sample homes in that area. If
EPA gathers additional data that shows that Site-related PFAS contamination is

19

-------
impacting or potentially impacting human health in Wendy Circle, EPA may adjust the
cleanup plan to extend the waterline farther.

Comment #15

Comment: A resident asked: "Why don't we just make a filtration device and hand out
to the locals9 Why do we have to make a whole line9"

Response: Currently, there are several homes that do have POETS installed in their home
to treat their well water. In the Proposed Plan for the Interim ROD, EPA presented its
evaluation of remedial alternatives which included both POETS (Alternative 2) and the
extension of the public waterline (Alternative 3). Because POETS can fail if not properly
maintained and result in short-term exposure until maintenance is performed, EPA
determined that the extension of the waterline is more protective of human health because
it permanently eliminates the potential use of contaminated groundwater as a drinking
water source and provides drinking water that is in compliance with federal and state
drinking water standards.

Comment #16

Comment: During the public meeting, a resident asked: "Is there a graph somewhere
that would say, hey, a family of two uses this much water, a family of four uses this
much water, a family of six uses this much water9"

Response: EPA is not aware of such a graph. However, according to EPA's Water Sense
webpage https://www.epa.gov/watersense/understanding-vour-water-
bill#:~:text=The%20average%20American%20uses%20around,oP/o20differences%20in
%20weather%20patterns. the average American uses about 82 gallons of water per day or
about 2,500 gallons per month. PAW's 2023 residential water service charge is $17.50
per month and the water usage rate is $1.6108 per every 100 gallons per month. See
https://www.amwater.com/paaw/customer-service-billing/vour-water~and-wastewater-
ratcs.

Comment #17

Comment: A commenter asked who is responsible for the contamination and why the
burden to provide safe drinking water isn't being placed on them.

Response: One goal of the Superfund enforcement program is to make responsible
parties pay for the environmental damage they have caused. As part of its enforcement
program, EPA investigates potentially responsible parties who may have contributed to
Site contamination. That process is on-going for this Site and if a viable responsible
party is identified, EPA would work toward recovering costs expended on the Site from
this responsible party.

Comment #18

20

-------
Comment: During the public meeting, a resident asked: "Does EPA sample residential

wells for PFAS?"

Response: Yes. Since July 2021, EPA has sampled numerous monitoring wells and
residential wells for PFAS at the Site. The last sampling event for PFAS occurred in
February and March of 2023. EPA sampled 33 residential wells with a focus on the
Karen Circle area.

Comment #19

Comment: During the public meeting, a resident asked: "We were about 100 yards
outside the plume area for PFAS. Will the EPA pay for our water hookup9"

Response: EPA will cover the cost of waterline hook up for properties located within the
identified AOC. As described in this ESD, the AOC includes the area within the
footprint of the contamination as well as a buffer area around the contamination. The
extent of the buffer area will be determined during the Remedial Design. Since the
issuance of the Interim ROD, EPA has identified a list of homes within the AOC to make
offers for connection to the waterline. If a property is outside of the current AOC, EPA
has not offered to connect the property to the waterline at this time. It is possible that the
AOC could expand when additional data become available. If new data demonstrate that
additional properties are impacted or potentially impacted by Site COCs, the AOC will be
expanded and EP A will offer and pay for the connection of these additional properties.
Properties outside the AOC will be able connect to the waterline at their own expense.

Comment #20

Comment: During the public meeting, a resident asked: "Has EPA tested on Garrett and
only up against the land trust [which border the Karen Circle area] or are you crossing
the road9"

Response: EPA sampled all across Karen Circle but was limited to those properties for
which we were able to obtain access to sample the residential well. However, EPA is
offering connections to the new public waterline to all residences in what is referred to as
"the Karen Circle Area", an area that includes both Karen Circle and Jodi Drive.

Comment #21

Comment: During the public meeting, an attendee stated: "So let's just say a few years
have passed. All the designing has been thought out. So by the time you start working
what if the coal contaminant has dispersed throughout the area and it's no longer a
concern9"

Response: The current extent of contamination is widespread across the Site, so it is not
likely that it would disperse quickly enough to no longer be a concern. Groundwater
contamination may be stable in some areas or otherwise moves slowly. Based on EPA's
experience working on other Sites with similar conditions, groundwater contamination
will be present at this Site until a remedy is selected in a future decision document and

21

-------
implemented to address the groundwater contamination. Furthermore, there is no COC
identified related to coal.

Comment #22

Comment: A resident at the public meeting inquired: "We are on a fixed income. What
if this bill is getting prohibitive for us and we decided to go back on our well water
because it's not contaminated, let's say? What happens9"

Response: If a resident chooses to connect to the new public waterline, EPA will
disconnect their indoor plumbing from their residential well and abandon the well, unless
a resident chooses to keep their well for non-potable purposes. If a resident wants to re-
connect their indoor plumbing to their residential well, the resident must meet certain
Chester County Health Department permit requirements for residential wells. Chester
County is responsible for issuing permits for residential wells. Chapter 500, Section
501, of the Chester County Health Department Rules and Regulations outlines the
requirements and restrictions for issuing such permits. Additionally, as part of the
Selected Remedy, ICs will be implemented to restrict potable use of untreated
groundwater within the contaminated plumes along with a prohibition on the installation
of any new groundwater wells within the lateral extent of the plumes until remediation
standards and protectiveness have been achieved, unless EPA, in consultation with
PADEP, gives prior written approval for such installation. If such approval is granted,
any costs for re-connecting indoor plumbing to a residential well would be the
responsibility of the homeowner.

Comment #23

Comment: Several residents in the public meeting, and one by phone, commented on the
cost of public water and indicated that they cannot afford a monthly water bill.

Response: EPA acknowledges that there would be a monthly water bill for each resident
who connects to the public waterline and notes that residents are not required to connect
their home to the public waterline. However, while there is no obligation to connect, it
would provide a permanent public water supply (with mandated monitoring
requirements) eliminating unacceptable risks resulting from the use of contaminated
residential well water and protect against new or emerging contaminants, such as
PFOA/PFOS. Additionally, although there are some costs associated with connection to a
public waterline, there are also costs associated with well water, including electric, pump
repair and routine maintenance.

Comment #24

Comment: A resident inquired whether the water meter would be located inside or
outside of the house.

Response: The location of the water meter will be determined during the design process
and based on PAW specifications.

22

-------
Comment #25

Comment: Several questions were raised about surface water flow versus groundwater
movement at the Site. For instance, one resident stated: "My mom gets water that runs
down from Karen Circle through her backyard past our well all the time. So whatever
contaminants that are still in the water in the ground or whatever, it's been 40, 50 years of
this happening... And I know water runs downhill. It do[es]n't run uphill."

Response: Surface water flows downhill. Flow of surface waters that may be impacting
areas downgradient are not related to the flow of groundwater beneath the surface.
Groundwater exists below the ground surface and is stored in spaces between soil grains,
rock particles, or in the case of this Site, predominantly in the fractures and faults within
in the bedrock underlying the Site. Groundwater flows in this network of complex
fractures and faults in the bedrock in a general eastward direction and in some places it
discharges to the surface water bodies at the Site. This discharge to surface water
provides a base flow to the stream system of Rock Run, Buck Run, and their tributaries.
Groundwater movement controls the flow of contamination as that is where Site-related
contamination is present. While groundwater discharges to surface water at this Site, the
extent of contamination has been delineated and does not extend to where groundwater
discharges to surface water. Monitoring wells are used to determine groundwater flow
direction at the Site.

Comment #26

Comment: A commenter inquired about whether there is a bidding process for installing
service lines from the main waterline to the individual homes.

Response: Yes, installation of the waterline will be subject to a bidding process. Under
EPA's contracting mechanisms for design and construction projects, bidding for these
types of projects is limited to a suite of vetted contractors. Bidding is not open outside of
this suite. Any sub-contracting of smaller firms is under the discretion of the prime
contractor and not conducted by EPA.

Comment #27

Comment: An individual emailed EPA expressing concern regarding the quality of water
that will be provided by PAW.

Response: PAW, a regulated public utility, is required by law to meet all drinking water
standards. Additionally, in January 2023, PADEP established monitoring requirements
for PFOA and PFOS for all community water systems beginning January 2024 for
systems serving more than 350 persons. Systems serving 350 people or fewer will be
required to monitor for PFOA and PFOS beginning on January 1, 2025. Repeat
monitoring is quarterly, annual, or triennial, based on whether analytical results are
detected and at what level. On an annual basis, community water systems are required to
mail or otherwise deliver a copy of a water quality report (Consumer Confidence Report)

-------
to each customer. PAW's 2022 Consumer Confidence Report is available here:

https://www.amwater.com/ccr/coatesville.pdf. For more information, please contact
PAW directly at 1-800-565-7292 or the PADEP Safe Drinking Water program for more
information: PADEP Safe Drinking Water: 484.250.5980 or RA-EPSDW-SERO-
OPS@pa.eov.

Comment #28

Comment: Is it possible the Site is affecting Coatesville Reservoir9

Response: It is unlikely. Site COCs have not been found in surface water which feeds the
Coatesville Reservoir, and monitoring data currently shows the groundwater plume is
contained and not expanding.

Comment #29

Comment: Have you looked into sampling the pond on Old Mill Road9

Response: Surface water samples were collected from the pond on Old Mill Road and no
Site-related contamination was found.

Subject:	Organic Data Validation (S4VM)

Old Wilmington Road Groundwater
R35961 C08Q0

Overview

This data package consisted often (10) Field Reagent Blanks (FRBs) and eleven (11) groundwater
samples analyzed for perfluorinated alkyl acid compounds by Liquid Chromatography/Mass
Spectrometry (LC/MS). This sample set included a field duplicate sample.

Analyses were performed	The samples were submitted to the

laboratory directly by the sampling contractor. The laboratory indicated analyses were performed
according to EPA Method 537.1 utilizing a quantitative isotope dilution-internal standard
technique.

Data were validated according to the National Functional Guidelines for Organic Superfund
Methods Data Review and applicable USEPA Region 3 modifications. The validation report has
been assigned the Superfund Data Validation Label S4VM (Stage_4_Validation_Manual).

The following validation narrative is an evaluation of laboratory reported data based on the
electronic data package received by Region 3 on September 16, 2021.

The laboratory did not provide sufficient data to determine if branched chain isomers of PFOA
were included in the reporting of this analyte in field samples. No data were qualified based on
this finding.

Summary

Blank contamination outlier was identified the required the rejection of a sample result.

-------
Page 2 of 4

Major Problem

FRB C08Q9 reported Perfluorooctanesulfonic Acid (PFOS) greater than 1/3* Method Reporting
Limit (MRL). Associated sample C08Q8 reported a positive result for PFOS less than lOx the blank
result. The result for PFOS in this sample has been rejected and qualified "R".

Notes

Concentrations of target analytes reporting less than the MRLs are estimated and have been
qualified "J".

Results less than the MRL for multiple field samples in the Electronic Data Deliverable (EDD) were
reported as non-detect and values reported as zero due to the format cell decimal settings. The
EDD has been revised for these results by the reviewer. They have been marked as detected and
qualified J.

Accuracy and precision criteria were met by the laboratory in the initial and continuing calibration
verification standard analyses for samples in this Sample Delivery Group (SDG).

Method blanks associated with field samples in this SDG were free from contamination except
method blank 181137. MBLK-181137 reported PFOS less than 1/3* MRL. Detected concentrations
for PFOS in the associated samples were greater than the blank result and were not qualified
based on method blank contamination.

FRB C08R3 reported Perfluorohexanesulfonic Acid (PFHxS) and Perfluorooctanoic Acid (PFOA) less
than 1/3* MRL. Detected concentration for PFHxS in associated sample C08R2 was less than the
MRL and has been reported at the MRL then qualified "U". Detected concentration for PFOA was
greater than the blank result and was not qualified based on blank contamination.

All other FRBs were free from contamination.

Percent recoveries for target analytes in the Laboratory Control Sample (LCS) analyses were
within control limits. No field sample data were qualified based on LCS accuracy.

Matrix Spike/Matrix Spike Duplicate (MS/MSD) analyses were not performed on samples in this
SDG.

The laboratory reported samples C08Q2 and C08Q6 had sand in the sample matrix. Sample C08Q8
had floating solids in the matrix. No data were qualified based on these findings.

Samples C08R6 and C08R8 clogged SPE cartridge during extraction. These samples required a ten-
fold (lOx) and five-fold (5x) dilutions, respectively prior to analyses due to sample matrix issues.
The MRLs in these samples were elevated. No data were qualified based on these findings.

Sample C08R4 reported the area count for internal standard d3-N-MeFOSAA outside the upper
control limits. Samples C08R4 and C08S0 reported low surrogate recoveries for d5-NEtFOSAA. The

R35961 C08Q0 DCN: ESATR3-CY1-4330

-------
Page 3 of 4

analytes associated with internal standard d3-N-MeFOSAA and surrogate d5-NEtFOSAA are not
listed as target analytes reported for this SDG. No data were qualified based on this outlier.

The samples in this SDG were preserved with Trizma. The pH values for only half of the field
samples were included in the data package. No data were qualified based on these findings.

Reported results for field duplicate pair C08Q8/C08R0 were comparable. No data were qualified
based on field duplicate precision.

Manual integrations were performed and identified by the laboratory. A subset of these was
evaluated by the reviewer and found to be accurate and consistent. No action was taken by the
reviewer based on manual integrations.

Sample calculation checks were performed. All calculated results had RPDs less than 5% of the
reported results. No sample data were qualified.

Validation qualifiers are only applied by the validator to field samples.

Validation In order of descending precedence. Only one of these qualifiers may apply to any
Qualifiers result.

R The data are unusable. The sample results are rejected due to serious deficiencies

in meeting QC criteria. The analyte may or may not be present in the sample.

UJ The analyte was analyzed for, but was not detected. The reported quantitation

limit is approximate and may be inaccurate or imprecise.

U The analyte was analyzed for, but was not detected above the level of the

reported sample quantitation limit.

J The result is an estimated quantity. The associated numerical value is the

approximate concentration of the analyte in the sample.

J+ The result is an estimated quantity, but the result may be biased high.

J- The result is an estimated quantity, but the result may be biased low.

„ ,.r. Additional qualifiers may be combined with other qualifiers.
Qualifiers

N The analyte has been "tentatively identified" or "presumptively" as present.

B The result is presumed a blank contaminant. This qualifier is used for drinking

water samples only.

C The target Pesticide or Aroclor analyte identification has been confirmed by Gas

Chromatography/Mass Spectrometry (GC/MS). This qualifier may be added to
other qualifiers.

X The target Pesticide or Aroclor analyte identification was not confirmed when

GC/MS analysis was performed. This qualifier may be added to other qualifiers.

Report Narrative

Per- and polyfluoroalkyl substance Analysis Note:

Not enough sample volume was available to prepare a matrix spike/matrix spike duplicate in batch BH21801.

Sample 2208013-18 had a glue-like consistency which prevented extraction. The sample was cancelled, no data are reported.

In field reagent blank 2208013-09, PFOA was detected at a level greater than 1/3 the method quantitation limit. Matching sample
results in 2208013-07 are qualified Bl, denoting possible blank contamination. The affected sample is invalid for compliance
testing and should be resampled.

Results and quantitation limits are qualified as estimated (J or UJ) for HFPO-DA, PFBS, and PFFlxA in all samples, because
recoveries in the associated blank spikes (BF121801-BS1 and BF122501-BS1) are outside acceptance criteria.

Results and quantitation limits for F1FPO-DA, NEtFOSAA, PFBS, PFFlxS, PFFlxA, and PFOS are qualified as estimated (J or UJ)
in sample 2208013-14, because recoveries and/or relative percent difference in the associated matrix spike and matrix spike
duplicate (BF121801-MS1 and BF121801-MSD1) are outside acceptable criteria.

Results and quantitation limits for all analytes are qualified as estimated (J or UJ) in samples 2208013-05, 15, 16, and 19 because
one or more surrogate were recovered outside acceptance criteria.

Notes and Definitions

UJ	The analyte was not detected at or above the quantitation limit. The quantitation limit is an estimate.

J	The identification of the analyte is acceptable; the reported value is an estimate.

B1	Method analyte is present in the associated field reagent blank (FRB) at a concentration greater than one-third the method reporting

limit. The sample is considered invalid for drinking water compliance monitoring and should be recollected.

A	Quality control value is outside acceptance limits.

%REC Percent Recovery

RPD Relative Percent Difference

U	Analyte included in the analysis, but not detected at or above the quantitation limit.

NR	Not Reported

QUANTITATION LIMIT: The lowest concentration of an analyte that can be reliably measured within specified limits of precision and accuracy
for a specific laboratory analytical method and that takes into account analytical adjustments made during sample preparation and analysis.

SOLID SAMPLE RESULTS - REPORTING PROTOCOL: Percent Solids (percent dry wt at 105 degrees C) determinations are routinely performed for
most organic and inorganic analyses. Consequently, these samples are analyzed wet and converted to a dry weight result for reporting purposes. If metals
and mercury analyses are requested, they are routinely prepared for analyses by an initial drying at 60 degrees C, homogenized prior to digestion, and are
analyzed and reported on a dry weight basis. Oil-type samples are analyzed and reported on a wet weight basis for all analyses because of the nature of the
sample matrix. Any exceptions to this protocol will be noted in the narrative.

ON-DEMAND: The term 'on-demand' analysis, if noted in the report narrative, refers to Section 13.1.2 in the Region 3 Laboratory Quality Manual, which
provides procedures for non-routine analyses or analytes.

R36339 410-116392-1

Overview

This data package consisted of eight (8) Field Reagent Blanks (FRBs), two (2) rinse blanks, and nine
(9) groundwater samples analyzed for perfluorinated alkyl acid compounds by Liquid
Chromatography/Mass Spectrometry (LC/MS). This sample set included a field duplicate sample.

Analyses were	The

samples were submitted to the laboratory directly by the sampling contractor. The laboratory
indicated analyses were performed according to EPA Method 537.1 utilizing a quantitative
isotope dilution-internal standard technique.

Data were validated according to ICF/ESAT SOP R3QA650 (Standard Operating Procedure for
Organic Data Review and Data Validation Report Preparation). The validation report has been
assigned the Superfund Data Validation Level Stage_4_Validation_Manual (S4VM).

The following validation narrative is an evaluation of laboratory reported data based on the
electronic data package received by Region 3 on April 28, 2023.

The laboratory did not provide sufficient data to determine if branched chain isomers of PFOA
were included in the reporting of this analyte in field samples. No data were qualified based on
this finding.

Field QC sample WS-0007 (410-116392-3) (Field Duplicate from SDG 410-116222-1) was
associated with samples in this SDG and used in the evaluation of this data.

Summary

A holding time outlier was identified that required the rejection of sample results.

-------
Page 2 of 3

Major Problem

The initial analysis of sample WS-0032 (410-116480-5) reported surrogate recoveries less than
10%. This sample was re-extracted outside of the technical holding time but reported surrogates
within control limits. The reanalysis of this sample was reported by the validator. The technical
holding time of fourteen (14) days from the time of sample collection to sample extraction has
been exceeded by twenty-one (21) days. Detected concentrations in this sample are estimated
and have been qualified Non-detects are unusable and have been qualified "R".

Notes

Target analytes detected below Limit of Quantitation (LOQ) are estimated and have been
qualified "J".

Accuracy and precision criteria were met by the laboratory in the initial and continuing calibration
verification standard analyses associated with the samples in this Sample Data Group (SDG).

The laboratory noted samples from SDG 410-116480-1 were merged into SDG 410-116392-1. No
data were qualified based on this finding.

FRBs, rinse, and method blanks associated with samples in this SDG were free from
contamination.

Percent recoveries for target analytes in Laboratory Control Sample (LCS) analyses were within
control limits. No field sample data were qualified based on LCS accuracy.

Percent recoveries for target analytes in Low Level Laboratory Control Sample (LCS) analyses were
within control limits. No field sample data were qualified based on LCS accuracy.

Percent recoveries and Relative Percent Differences (RPDs) for target analytes in Matrix
Spike/Matrix Spike Duplicate (MS/MSD) analyses of sample WS-0036 (410-116392-12) were
within control limits. No data were qualified based on MS/MSD precision or accuracy.

Field duplicate pair WS-007 (410-116392-l)/WS-0040 (410-116392-14) were comparable. No data
were qualified based on field duplicate precision.

The samples in this SDG were found to be free of residual chlorine at the time of sample
preparation by the laboratory. No data were qualified based on this finding.

The peak asymmetry factor for the first two eluting peaks in the mid-level calibration standard
were within control limits. No data were qualified based on this finding.

The samples in this SDG were preserved and reported pH within the optimum range (pH range 6-
8). No data qualified based on this outlier. No data were qualified based on these findings.

Manual integrations were performed and identified by the laboratory. A subset of these were
evaluated by the reviewer and were found to be accurate and consistent. No action was taken by
the reviewer based on manual integrations.

Sample calculation checks were performed. Calculated results had RPDs less than 5% of the
reported results. No sample data were qualified.

Validation qualifiers are only applied by the validator to field samples.

Glossary of Organic Data Qualifier Codes
Validation In order of descending precedence. Only one of these qualifiers may apply to any
Qualifiers result.

R	The data are unusable. The sample results are rejected due to serious deficiencies

in meeting QC criteria. The analyte may or may not be present in the sample.

UJ	The analyte was analyzed for, but was not detected. The reported quantitation

limit is approximate and may be inaccurate or imprecise.

U	The analyte was analyzed for, but was not detected above the level of the

reported sample quantitation limit

J	The result is an estimated quantity. The associated numerical value is the

approximate concentration of the analyte in the sample.

J+	The result is an estimated quantity, but the result may be biased high.

J-	The result is an estimated quantity, but the result may be biased low.

Qualifiers Additional qualifiers may be combined with other qualifiers.

N	The analyte has been "tentatively identified" or "presumptively" as present.

B	The result is presumed a blank contaminant. This qualifier is used for drinking

water samples only.

C	The target Pesticide or Aroclor analyte identification has been confirmed by Gas

Chromatography/Mass Spectrometry (GC/MS). This qualifier may be added to
other qualifiers.

X	The target Pesticide or Aroclor analyte identification was not confirmed when

GC/MS analysis was performed. This qualifier may be added to other qualifiers.

Subject:	Organic Data Validation (S4VM)

Old Wilmington Road
R36339 410-116222-1

Overview

This data package consisted of seven (7) Field Reagent Blanks (FRBs), one (1) rinse blank, and
twelve (12) groundwater samples analyzed for perfluorinated alkyl acid compounds by Liquid
Chromatography/Mass Spectrometry (LC/MS). This sample set included a field duplicate sample,

samples were submitted to the laboratory directly by the sampling contractor. The laboratory
indicated analyses -were performed according to EPA Method 537.1 utilizing a quantitative
isotope dilution-internal standard technique.

Data were validated according to iCF/ESAT SOP R3QA650 (Standard Operating Procedure for
Organic Data Review and Data Validation Report Preparation). The validation report has been
assigned the Superfund Data Validation Level Stage_4_Validation_Manual (S4VM).

The following validation narrative is an evaluation of laboratory reported data based on the
electronic data package received by Region 3 on April 23, 2023.

The laboratory did not provide sufficient data to determine if branched chain isomers of PFOA
were included in the reporting of this ana'yte in field samples. No data were qualified based on
this finding.

Summary

An FRB outlier was identified that required the rejection of sample results. Less significant data
quality outliers were identified resulting in estimation of sample results including but not limited
to, surrogate recoveries and internal standard recoveries as detailed below.

-------
Page 2 of 4

Major Problem

FRB WS-006 (410-116392-2) reported detected concentrations of Perfluorohexanoic acid,
Perfluoroheptanoic acid, Perfluorooctanoic acid, Perfluorononanoic acid, Perfluorobutanesulfonic
Acid, Perfluorohexanesulfonic acid, and Perfluorooctanesulfonic acid greater than 1/3 times Limit
of Quantitation (LOQ). Detected concentrations of Perfluorohexanoic acid, Perfluoroheptanoic
acid, Perfluorooctanoic acid, Perfluorobutanesulfonic Acid, Perfluorohexanesulfonic acid, and
Perfluorooctanesulfonic acid in associated sample WS-005 (410-116392-1) were less than lOx of
the blank contamination. The results for these analytes are unusable and have been qualified
rejected "R".

Minor Problems

The percent recoveries for the following surrogates were outside the lower control limit for the
samples listed below. These samples were reanalyzed outside of the technical holding reporting
similar results. The initial analyses were reported. Detected concentrations for analytes
associated with these surrogates are estimated and qualified "J-". Non-detects are estimated and
have been qualified "UJ".

WS-0026 (410-116222-10)

13C2 PFDA and d5-NEtFOSAA

WS-0028 (410-116222-12)

The area count for internal standard 13C4-PFOS was outside of the upper control limit for the
sample WS-0027 (410-116222-11). This sample was reanalyzed outside of the technical holding
time. The initial analysis was reported. Detected concentrations for associated analytes are
estimated and has been qualified "J". Non-detects are not qualified based on this outlier.

Notes

Target analytes detected below LOQ are estimated and have been qualified "J".

Accuracy and precision criteria were met by the laboratory in the initial and continuing calibration
verification standard analyses associated with the samples in this Sample Data Group (SDG).

The laboratory noted samples from SDG 410-116392-1 (samples 1 through 5) were merged into
SDG 410-116222-1. No data were qualified based on this finding.

FRB WS-008 (410-116392-4) reported Perfluorobutanesulfonic acid greater than 1/3 times the
LOQ. Associated samples WS-007 (410-116392-3) and WS-009 (410-116392-5) were non-detect
for this analyte. No data were qualified based on FRB contamination. All other FRBs associated
with the samples in this SDG were free from contamination with the exception of the FRB
mentioned in "Major Problem".

The method blanks were free from contamination.

Page 3 of 4

Rinse blank WS-0039 (410-116222-15) was free from contamination.

Percent recoveries for target analytes in Laboratory Control Sample (LCS) analyses were within
control limits. No field sample data were qualified based on LCS accuracy.

The concentration of perfluorooctanesulfonic acid exceeded the calibration range in the initial
analysis for sample WS-0028 (410-116222-12). This sample was reanalyzed at a ten-fold (10X)
dilution in order to quantitate this analyte within the calibration range and was reported from the
dilution. Surrogate recovery does not apply to a sample that has been diluted.

Percent recoveries and Relative Percent Differences (RPDs) for target analytes in Matrix
Spike/Matrix Spike Duplicate (MS/MSD) analyses of sample WS-0001 (410-116222-1) were within
control limits. No data were qualified based on MS/MSD precision or accuracy.

Field duplicate pair WS-0015 (410-116222-3)/WS-0038 ( 410-116222-14) were comparable. No
data were qualified based on field duplicate precision.

The samples in this SDG were found to be free of residual chlorine at the time of sample
preparation by the laboratory. No data were qualified based on this finding.

The peak asymmetry factor for the first two eluting peaks in the mid-level calibration standard
were within control limits. No data were qualified based on this finding.

The samples in this SDG were preserved and reported pH within the optimum range (pH range 6-
8). The pH for sample WS-005 (410-116392-1) is within range. No data qualified based on this
outlier. No data were qualified based on these findings.

Manual integrations were performed and identified by the laboratory. A subset of these were
evaluated by the reviewer and were found to be accurate and consistent. No action was taken by
the reviewer based on manual integrations.

Sample calculation checks were performed. Calculated results had RPDs less than 5% of the
reported results. No sample data were qualified.

Validation qualifiers are only applied by the validator to field samples.

Glossary of Organic Data Qualifier Codes	

Validation In order of descending precedence. Only one of these qualifiers may apply to any
Qualifiers result.

R	The data are unusable. The sample results are rejected due to serious deficiencies

in meeting QC criteria. The analyte may or may not be present in the sample.

UJ	The analyte was analyzed for, but was not detected. The reported quantitation

limit is approximate and may be inaccurate or imprecise.

U	The analyte was analyzed for, but was not detected above the level of the

reported sample quantitation limit

J	The result is an estimated quantity. The associated numerical value is the

approximate concentration of the analyte in the sample.

J+	The result is an estimated quantity, but the result may be biased high.

J-	The result is an estimated quantity, but the result may be biased low.

Qualifiers Additional qualifiers may be combined with other qualifiers.

N	The analyte has been "tentatively identified" or "presumptively" as present.

B	The result is presumed a blank contaminant. This qualifier is used for drinking

water samples only.

C	The target Pesticide or Aroclor analyte identification has been confirmed by Gas

Chromatography/Mass Spectrometry (GC/MS). This qualifier may be added to
other qualifiers.

X	The target Pesticide or Aroclor analyte identification was not confirmed when

GC/MS analysis was performed. This qualifier may be added to other qualifiers.

Overview

This data package consisted of ten (10) Field Reagent Blanks (FRBs) and ten (10) groundwater
samples analyzed for perfluorinated alkyl acid compounds by Liquid Chromatography/Mass
Spectrometry (LC/MS). The sample set included one (1) field duplicate sample.

Analyses were	The

samples were submitted to the laboratory directly by the sampling contractor. The laboratory
indicated analyses were performed according to EPA Method 537.1 utilizing a quantitative
isotope dilution-internal standard technique.

Data were validated according to ICF/ESAT SOP R3QA650 (Standard Operating Procedure for
Organic Data Review and Data Validation Report Preparation). The validation report has been
assigned the Superfund Data Validation Level Stage_4_Validation_Manual (S4VM).

The following validation narrative is an evaluation of laboratory reported data based on the
electronic data package received by Region 3 on April 28, 2023.

FRB WS-0098 (from Sample Delivery Group (SDG) 410-117263-1) was associated with sample field
sample WS-0097 in this SDG and used in the evaluation of this data.

The laboratory did not provide sufficient data to determine if branched chain isomers of PFOA
were included in the reporting of this analyte in field samples. No data were qualified based on
this finding.

Summary

No data quality outliers or technical deficiencies were identified that would require rejection or
estimation of sample results.

Notes

Target analytes detected below Limit of Quantitation (LOQ) are estimated and have been
qualified "J".

Accuracy and precision criteria were met by the laboratory in the initial and continuing calibration
verification standard analyses associated with the samples in this SDG.

Surrogates and internal standards were within control limits.

FRBs and method blanks associated with samples in this SDG were free from contamination.

Percent recoveries for target analytes in Laboratory Control Sample (LCS) analyses were within
control limits. No field sample data were qualified based on LCS accuracy.

Chain of Custody records list sample WS-0054 as a field duplicate; however, records did not
include reference regarding the identification of the corresponding sample. Therefore, no
comparison was made by the reviewer.

The samples in this SDG were found to be free of residual chlorine at the time of sample
preparation by the laboratory. No data were qualified based on this finding.

The peak asymmetry factor for the first two eluting peaks in the mid-level calibration standard
were within control limits. No data were qualified based on this finding.

The samples in this SDG were preserved and reported pH within the optimum range (pH range 6-
8). No data qualified based on this outlier. No data were qualified based on these findings.

Sample calculation checks were performed. Calculated results had RPDs less than 5% of the
reported results. No sample data were qualified.

Manual integrations were performed and identified by the laboratory. A subset of these were
evaluated by the reviewer and were found to be accurate and consistent. No action was taken by
the reviewer based on manual integrations.

Validation qualifiers are only applied by the validator to field samples.

Glossary of Organic Data Qualifier Codes	

Validation In order of descending precedence. Only one of these qualifiers may apply to any
Qualifiers result.

R	The data are unusable. The sample results are rejected due to serious deficiencies

in meeting QC criteria. The analyte may or may not be present in the sample.

UJ	The analyte was analyzed for, but was not detected. The reported quantitation

limit is approximate and may be inaccurate or imprecise.

U	The analyte was analyzed for, but was not detected above the level of the

reported sample quantitation limit

J	The result is an estimated quantity. The associated numerical value is the

approximate concentration of the analyte in the sample.

J+	The result is an estimated quantity, but the result may be biased high.

J-	The result is an estimated quantity, but the result may be biased low.

Qualifiers Additional qualifiers may be combined with other qualifiers.

N	The analyte has been "tentatively identified" or "presumptively" as present.

B	The result is presumed a blank contaminant. This qualifier is used for drinking

water samples only.

C	The target Pesticide or Aroclor analyte identification has been confirmed by Gas

Chromatography/Mass Spectrometry (GC/MS). This qualifier may be added to
other qualifiers.

X	The target Pesticide or Aroclor analyte identification was not confirmed when

GC/MS analysis was performed. This qualifier may be added to other qualifiers.

Overview

This data package consisted of seven (7) Field Reagent Blanks (FRBs) and ten (10) ground water
samples analyzed for perfluorinated alkyl acid compounds by Liquid Chromatography/Mass
Spectrometry (LC/MS). The sample set included one (1) field duplicate sample.

Analyses were	by	The

samples were submitted to the laboratory directly by the sampling contractor. The laboratory
indicated analyses were performed according to EPA Method 537.1 utilizing a quantitative
isotope dilution-internal standard technique.

Data were validated according to ICF/ESAT SOP R3QA650 (Standard Operating Procedure for
Organic Data Review and Data Validation Report Preparation). The validation report has been
assigned the Superfund Data Validation Level Stage_4_Validation_Manual (S4VM).

The following validation narrative is an evaluation of laboratory reported data based on the
electronic data package received by Region 3 on April 28, 2023.

The laboratory did not provide sufficient data to determine if branched chain isomers of PFOA
were included in the reporting of this analyte in field samples. No data were qualified based on
this finding.

Summary

FRB outliers were identified that required the rejection as well as the estimation of sample
results.

-------
Page 2 of 4

Major Problem

FRB WS-0062 (410-117141-4) detected concentrations of Perfluorohexanoic acid,
Perfluoroheptanoic acid, Perfluorooctanoic acid, Perfluorobutanesulfonic acid,
Perfluorohexanesulfonic acid and Perfluorooctanesulfonic acid were greater than 1/3 times the
Limit of Quantitation (LOQ). Associated sample WS-0061 (410-117141-3) was non-detect for these
target analytes. Detected concentrations of these analytes in associated samples WS-0059 (410-
117141-1) and WS-0060 (410-117141-2) were less than lOx the blank results. The results for these
analytes are unusable and have been qualified as rejected "R".

Minor Problem

FRB WS-0071 (410-117141-13) reported detected concentrations of Perfluorobutanesulfonic acid
less than 1/3 time the LOQ. The result for this analyte in associated sample WS-0070 is estimated
and has been qualified "J+".

Notes

Target analytes detected below LOQ are estimated and have been qualified "J".

The laboratory noted the reporting limits were elevated in samples WS-0063 (410-117141-5) and
WS-0069 (410-117141-11) due to limited sample volume. No data were qualified based on this
outlier.

Accuracy and precision criteria were met by the laboratory in the initial and continuing calibration
verification standard analyses associated with the samples in this Sample Delivery Group (SDG).

Surrogates and internal standards were within control limits.

Method blanks associated with samples in this SDG were free from contamination except method
blank 410-351267/1-A reported Perfluorotetradecanoic acid less than the LOQ. Associated sample
FRB WS-0071 (410-117141-13) was non-detect for this analyte. No data were qualified based on
method blank contamination.

FRBs associated with samples in this SDG were free from contamination except FRB WS-0062
(410-117141-4) and FRB WS-0071 (410-117141-13). Data were qualified as mentioned in
"Major/Minor Problems".

Percent recoveries for target analytes in Laboratory Control Sample (LCS) analyses were within
control limits. No field sample data were qualified based on LCS accuracy.

Percent recoveries and Relative Percent Differences (RPDs) for target analytes in Matrix
Spike/Matrix Spike Duplicate (MS/MSD) analyses of sample WS-0072 (410-117141-14) were
within control limits. No data were qualified based on MS/MSD precision or accuracy.

Field duplicate pair WS-0059 (410-117141-l)/WS-0060 (410-117141-2) were comparable. No data
were qualified based on field duplicate precision.

The samples in this SDG were found to be free of residual chlorine at the time of sample
preparation by the laboratory. No data were qualified based on this finding.

The peak asymmetry factor for the first two eluting peaks in the mid-level calibration standard
were within control limits. No data were qualified based on this finding.

The samples in this SDG were preserved and reported pH within the optimum range (pH range 6-
8). No data were qualified based on these findings.

Manual integrations were performed and identified by the laboratory. A subset of these were
evaluated by the reviewer and were found to be accurate and consistent. No action was taken by
the reviewer based on manual integrations.

Validation qualifiers are only applied by the validator to field samples.

Sample calculation checks performed on samples found Relative Percent Differences (RPDs) less
than five percent (5%) of the reported results. No sample data were qualified.

Glossary of Organic Data Qualifier Codes	

Validation In order of descending precedence. Only one of these qualifiers may apply to any
Qualifiers result.

R	The data are unusable. The sample results are rejected due to serious deficiencies

in meeting QC criteria. The analyte may or may not be present in the sample.

UJ	The analyte was analyzed for, but was not detected. The reported quantitation

limit is approximate and may be inaccurate or imprecise.

U	The analyte was analyzed for, but was not detected above the level of the

reported sample quantitation limit

J	The result is an estimated quantity. The associated numerical value is the

approximate concentration of the analyte in the sample.

J+	The result is an estimated quantity, but the result may be biased high.

J-	The result is an estimated quantity, but the result may be biased low.

Qualifiers Additional qualifiers may be combined with other qualifiers.

N	The analyte has been "tentatively identified" or "presumptively" as present.

B	The result is presumed a blank contaminant. This qualifier is used for drinking

water samples only.

C	The target Pesticide or Aroclor analyte identification has been confirmed by Gas

Chromatography/Mass Spectrometry (GC/MS). This qualifier may be added to
other qualifiers.

X	The target Pesticide or Aroclor analyte identification was not confirmed when

GC/MS analysis was performed. This qualifier may be added to other qualifiers.

Subject:	Organic Data Validation (S4VM)

Old Wilmington Road
R36339 410-117559-1

Overview

This data package consisted of eight (8) Field Reagent Blanks (FRBs) and twelve (12) ground water
samples analyzed for perfluorinated alkyl acid compounds by Liquid Chromatography/Mass
Spectrometry (LC/MS). This sample set included one (1) field duplicate sample.

Analyses were	by

samples were submitted to the laboratory directly by the sampling contractor. The laboratory
indicated analyses were performed according to EPA Method 537.1 utilizing a quantitative
isotope dilution-internal standard technique.

Data were validated according to ICF/ESAT SOP R3QA650 (Standard Operating Procedure for
Organic Data Review and Data Validation Report Preparation). The validation report has been
assigned the Superfund Data Validation Level Stage_4_Validation_Manual (S4VM).

The following validation narrative is an evaluation of laboratory reported data based on the
electronic data package received by Region 3 on April 28, 2023.

The laboratory did not provide sufficient data to determine if branched chain isomers of PFOA
were included in the reporting of this analyte in field samples. No data were qualified based on
this finding.

FRBs WS-0119 (410-117568-1), WS-120 (410-117568-2), WS-121 (410-117568-3) (From Sample
Delivery Group (SDG) 410-117017-1) were associated with samples in this SDG and used in the
evaluation of this data.

Summary

Holding time outliers were identified that required the rejection as well as the estimation of
sample results. Less significant data quality outliers were identified resulting in estimation of
sample results including but not limited to Matrix Spike/Matrix Spike Duplicate recoveries as
detailed below.

-------
Page 2 of 4

Major Problem

The initial analysis for the samples listed below reported low surrogate recoveries and recoveries
less than 10%. These samples were re-extracted outside of the technical holding time but
reported surrogates within control limits. The reanalyses of these samples were reported by the
validator. The technical holding time of fourteen (14) days from the time of sample collection to
sample extraction has been exceeded by twenty-one (21) days. Detected concentrations in these
samples are estimated and have been qualified "J-". Non-detects are unusable and have been
qualified "R".

Affected Samples

WS-107 (410-117559-9)
WS-108 (410-117559-10)

Minor Problem

The initial analysis of the MS/MSD for sample WS-106 (410-117559-8) reported multiple low
recoveries of target analytes and surrogates. The MS/MSD was re-extracted outside of technical
holding time. The re-extractions were reported by the validator. Percent recoveries and Relative
Percent Differences (RPDs) for target analytes in the MS/MSD analyses were within control limits
except for the analytes/RPDs listed below. Detected concentrations are estimated and have been
qualified "J". Non-detects are estimated and have been qualified "UJ" unless superseded by "R".

Notes

Target analytes detected below Limit of Quantitation (LOQ) are estimated and have been
qualified "J".

The laboratory noted the reporting limits were elevated in samples WS-0117 (410-117559-19)
due to limited sample volume. No data were qualified based on this outlier.

Accuracy and precision criteria were met by the laboratory in the initial and continuing calibration
verification standard analyses associated with the samples in this SDG.

FRBs and method blanks associated with samples in this SDG were free from contamination.

Percent recoveries for target analytes in Laboratory Control Sample (LCS) analyses were within
control limits. No field sample data were qualified based on LCS accuracy.

Percent recoveries for target analytes in Low Level Laboratory Control Sample (LLCS) analyses
were within control limits. No field sample data were qualified based on LLCS accuracy.

Field duplicate pair WS-104 (410-117559-6)/WS-110 (410-117559-12) were comparable. No data
were qualified based on field duplicate precision.

The samples in this SDG were found to be free of residual chlorine at the time of sample
preparation by the laboratory. No data were qualified based on this finding.

The peak asymmetry factor for the first two eluting peaks in the mid-level calibration standard
were within control limits. No data were qualified based on this finding.

The samples in this SDG were preserved and reported pH within the optimum range. No data
qualified based on this outlier. No data were qualified based on these findings.

Manual integrations were performed and identified by the laboratory. A subset of these were
evaluated by the reviewer and were found to be accurate and consistent. No action was taken by
the reviewer based on manual integrations.

Validation qualifiers are only applied by the validator to field samples.

Sample calculation checks performed on samples found Relative Percent Differences (RPDs) less
than five percent (5%) of the reported results. No sample data were qualified.

Glossary of Organic Data Qualifier Codes	

Validation In order of descending precedence. Only one of these qualifiers may apply to any
Qualifiers result.

R	The data are unusable. The sample results are rejected due to serious deficiencies

in meeting QC criteria. The analyte may or may not be present in the sample.

UJ	The analyte was analyzed for, but was not detected. The reported quantitation

limit is approximate and may be inaccurate or imprecise.

U	The analyte was analyzed for, but was not detected above the level of the

reported sample quantitation limit

J	The result is an estimated quantity. The associated numerical value is the

approximate concentration of the analyte in the sample.

J+	The result is an estimated quantity, but the result may be biased high.

J-	The result is an estimated quantity, but the result may be biased low.

Qualifiers Additional qualifiers may be combined with other qualifiers.

N	The analyte has been "tentatively identified" or "presumptively" as present.

B	The result is presumed a blank contaminant. This qualifier is used for drinking

water samples only.

C	The target Pesticide or Aroclor analyte identification has been confirmed by Gas

Chromatography/Mass Spectrometry (GC/MS). This qualifier may be added to
other qualifiers.

X	The target Pesticide or Aroclor analyte identification was not confirmed when

GC/MS analysis was performed. This qualifier may be added to other qualifiers.

Subject:	Organic Data Validation (S4VM)

Old Wilmington Road
R36339 410-117263-1

Overview

This data package consisted of eight (8) Field Reagent Blanks (FRBs) and twelve (12) groundwater
samples analyzed for perfluorinated alkyl acid compounds by Liquid Chromatography/Mass
Spectrometry (LC/MS). This sample set included one (1) field duplicate sample.

The

Analyses were performed byl
samples were submitted to t
indicated analyses were performed according to EPA Method 537.1 utilizing a quantitative
isotope dilution-internal standard technique.

Data were validated according to ICF/ESAT SOP R3QA650 (Standard Operating Procedure for
Organic Data Review and Data Validation Report Preparation). The validation report has been
assigned the Superfund Data Validation Level Stage_4_Validation_Manual (S4VM).

The following validation narrative is an evaluation of laboratory reported data based on the
electronic data package received by Region 3 on April 28, 2023.

The laboratory did not provide sufficient data to determine if branched chain isomers of PFOA
were included in the reporting of this analyte in field samples. No data were qualified based on
this finding.

Summary

No significant data quality outliers or technical deficiencies were identified that would require
rejection of sample results. Less significant data quality outliers were identified resulting in
estimation of sample results including but not limited to Matrix Spike/Matrix Spike Duplicate
(MS/MSD) recoveries as detailed below.

-------
Page 2 of 3

Minor Problem

Percent recoveries and Relative Percent Differences (RPDs) for target analytes in MS/MSD analysis
of sample WS-0094 (410-117263-17) were within control limits with the exception of
perfluorooctanesulfonic acid high recoveries in both the MS/MSD. Detected concentration for
perfluorooctanesulfonic acid in the parent sample is estimated and has been qualified "J".

Notes

Target analytes detected below Limit of Quantitation (LOQ) are estimated and have been
qualified "J".

Accuracy and precision criteria were met by the laboratory in the initial and continuing calibration
verification standard analyses associated with the samples in this Sample Delivery Group (SDG).

FRBs and method blanks associated with samples in this SDG were free from contamination.

Percent recoveries for target analytes in Laboratory Control Sample (LCS) analyses were within
control limits. No field sample data were qualified based on LCS accuracy.

Percent recoveries and Relative Percent Differences (RPDs) for target analytes in the LCS/LCSD
analyses were within control limits. No data were qualified based on LCS/LCSD precision or
accuracy.

The concentration of perfluorooctanesulfonic acid exceeded the calibration range in the initial
analysis for sample WS-0094 (410-117263-17). This sample was reanalyzed at a ten-fold (10X)
dilution in order to quantitate this analyte within the calibration range and was reported from the
dilution.

Field duplicate pair WS-0076 (410-117559-6)/WS-0079 (410-117559-12) were comparable. No
data were qualified based on field duplicate precision.

The samples in this SDG were found to be free of residual chlorine at the time of sample
preparation by the laboratory. No data were qualified based on this finding.

The peak asymmetry factor for the first two eluting peaks in the mid-level calibration standard
were within control limits. No data were qualified based on this finding.

The samples in this SDG were preserved and reported pH within the optimum range. No data
qualified based on this outlier. No data were qualified based on these findings.

Manual integrations were performed and identified by the laboratory. A subset of these were
evaluated by the reviewer and were found to be accurate and consistent. No action was taken by
the reviewer based on manual integrations.

Validation qualifiers are only applied by the validator to field samples.

R36339 410-117263-1	DCN: ESATR3-CY1-K230

Sample calculation checks performed on samples found Relative Percent Differences (RPDs) less
than five percent (5%) of the reported results. No sample data were qualified.

Glossary of Organic Data Qualifier Codes	

Validation In order of descending precedence. Only one of these qualifiers may apply to any
Qualifiers result.

R	The data are unusable. The sample results are rejected due to serious deficiencies

in meeting QC criteria. The analyte may or may not be present in the sample.

UJ	The analyte was analyzed for, but was not detected. The reported quantitation

limit is approximate and may be inaccurate or imprecise.

U	The analyte was analyzed for, but was not detected above the level of the

reported sample quantitation limit

J	The result is an estimated quantity. The associated numerical value is the

approximate concentration of the analyte in the sample.

J+	The result is an estimated quantity, but the result may be biased high.

J-	The result is an estimated quantity, but the result may be biased low.

Qualifiers Additional qualifiers may be combined with other qualifiers.

N	The analyte has been "tentatively identified" or "presumptively" as present.

B	The result is presumed a blank contaminant. This qualifier is used for drinking

water samples only.

C	The target Pesticide or Aroclor analyte identification has been confirmed by Gas

Chromatography/Mass Spectrometry (GC/MS). This qualifier may be added to
other qualifiers.

X	The target Pesticide or Aroclor analyte identification was not confirmed when

GC/MS analysis was performed. This qualifier may be added to other qualifiers.
