I. INTRODUCTION

The purpose of a Five-Year Review (FYR) is to evaluate the implementation and performance of a
remedy in order to determine if the remedy is and will continue to be protective of human health and the
environment. The methods, findings, and conclusions of reviews are documented in FYR reports such as
this one. In addition, FYR reports identify issues found during the review, if any, and document
recommendations to address them.

The United States Environmental Protection Agency (EPA) is preparing this FYR pursuant to the
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 121,
consistent with the National Contingency Plan (NCP)(40 CFR Section 300.430(f)(4)(ii)), and
considering EPA policy.

This is the fifth FYR for the Van Dale Junkyard Superfund Site (Site). The triggering action for this
statutory review is the completion date of the fourth FYR. The FYR has been prepared due to the fact
that hazardous substances, pollutants, or contaminants remain at the site above levels that allow for
unlimited use and unrestricted exposure (UU/UE).

The Site consists of one operable unit (OU) and a comprehensive site-wide review will be addressed in
this FYR.

The Van Dale Junkyard Superfund Site FYR was led by Bill Murray, EPA Remedial Project Manager.
Participants included David Wilson EPA Hydrogeologist; Adrian Palomeque, EPA Community
Involvement Coordinator; and Baxter Foskuhl, Ohio Environmental Protection Agency (OEPA) Site
Coordinator. OEPA and the Potentially Responsible Parties (PRPs) were notified in writing of the
initiation of the five-year review. The review began on 2/8/2023.

Site Background

The Site is located about 1.5 miles northeast of the City of Marietta in Washington County, Ohio, along
the rolling hills of the Appalachian Plateau (See Appendix B - Figures 1). Situated along the Ohio
River, Marietta has a population of approximately 13,000, based on 2020 Census data. The Site was a
former junkyard located on 31 acres in a rural residential area, occupying part of a natural ridge that runs
east to west. Primary land use in the area is agricultural and residential, with approximately 200
residences located within a one-mile radius of the Site. Farm animals graze on neighboring properties. A
closed landfill, the Marietta Sanitation Landfill, borders the Site to the south.

On-Site, a few unoccupied barns and two mobile home trailers are located at the top of the ridge
adjacent to the main access road. One of the trailers has been used as a residence since at least 2008,
while the other has been used for storage. At the time the Site was discovered, various scrap materials,
automobiles, and waste drums containing industrial solvents, tar, and sludges were located throughout
the Site. Historically, there was no known use of Site groundwater. Groundwater access in the area has
been inconsistent and unreliable. Currently, the on-site resident along with residents adjacent to and
surrounding the site use the City of Marietta's public water supply system as a drinking water source.
Surface water drainage from the Site flows through two intermittent streams to Duck Creek, a small
tributary to the Ohio River.

Investigations of hazardous substance disposal at the site began in 1980, when OEPA personnel first
visited the site. The site has a history of complaints to local authorities from nearby residents dating

3


-------
back to at least 1969. Most of the complaints appear to have been related to open-burning and accepting
wastes which created nuisances, such as odors and rodents. Based on observations of drummed waste at
the site in 1980, preliminary assessments of contamination at the site were conducted by EPA and
OEPA from 1980 to 1983. Based on the assessments of the release of hazardous substances at the site,
the site was proposed for inclusion on EPA's National Priorities List (NPL) for Superfund sites in
1982, and was finalized on the NPL in June 1986.

II. RESPONSE ACTION SUMMARY

Basis for Taking Action

As part of the RI, a baseline risk assessment (BLRA) was prepared to characterize the current and
potential threats to human health and the environment that may be posed by the Site through various

4


-------
exposure pathways such as ingestion and dermal contact (EPA, 1992). The BLRA identified the
following contaminants of concern (COCs), with media impacted, and determined
to be major potential health risks at the Site:

The BLRA stated that releases of Site-related contaminants, if not addressed, posed an imminent and
substantial endangerment to public health, welfare, and the environment. The contaminants which
contributed most to the elevated Site risks for human health included volatile organic compounds
(VOCs) such as tetrachloroethene, 1,1-dichloroethene, and vinyl chloride (VC), semivolatile organic
compounds (SVOCs) such as polycyclic aromatic hydrocarbons (PAHs) like naphthalene and
benzo(a)pyrene, and metals like arsenic, cadmium, and lead. The BLRA also concluded that
approximately 95 percent of the excess risk to human health associated with the Site is due to the
potential use of groundwater, with the remaining 5 percent associated with dermal contact with Site
soils. Contaminants contributing excess risks and hazards in groundwater were antimony, arsenic,
barium, bis(2-ethylhexyl) phthalate, cadmium, 1,1-dichloroethene (DCE), nickel, tetrachloroethene,
vanadium, and VC. For soil, contaminants contributing excess risks included antimony, arsenic, bis(2-
ethylhexyl)phthalate, lead, and PAHs such as naphthalene and benzo(a) pyrene.

Despite extensive habitat degradation at the Site due to disposal activities, diverse terrestrial and aquatic
habitats were observed over the north slope. Evaluation of Site contaminant levels against known

5


-------
toxicity thresholds indicated no toxic effects, with contaminant levels not exceeding chemical-specific
concentrations for either acute or chronic effects in wild or laboratory animals. Exceedances of surface
water quality criteria and standards suggested adverse effects on aquatic life may have been occurring,
particularly in the surface water and sediments in the seeps located on the north slope of the Site. No
endangered or threatened species were known to be present around the Site, based on available State
information.

Response Actions

OEPA visited the Site in 1980 and observed, among other things, drummed wastes at the Site. Later,
OEPA began to investigate the Site under the authority of CERCLA, conducting preliminary
assessments at the Site from 1980 to 1983.

Following investigations carried out under CERCLA, the State of Ohio filed a lawsuit against the
owner/operator of the Site in 1984. Eventually, the State of Ohio and the owner/operator reached a
settlement agreement. A key provision was that the agreement assured the State access to the Site for
further investigations.

Remedial Action Objectives

Following completion of the RI, EPA issued a FS for the Site in August 1992. This FS report presents
and discusses the process used to develop and screen remedial action alternatives for the Site. The FS
alternative evaluations are based on the results of the RI, including the Baseline Risk Assessment. EPA
signed a Record of Decision (ROD) for the Site on March 31, 1994 (EPA, 1994). The ROD identified
the following remedial action objectives (RAOs) for the Site:

•	Achieve a total Site risk of 1E-06 or less for carcinogens;

•	Achieve a total Site hazard index of 1 or less for noncarcinogens; and

•	Meet all applicable or relevant and appropriate requirements (ARARs).

Remedy Selected

The above RAOs were developed to aid in the development of the remedy for the Site. The selected
remedy in the ROD included the following components:

•	Collect and consolidate an estimated 9,000 cubic yards of soil and drummed waste materials
located beyond the Site containment area that contain organic and inorganic contaminants;

•	Segregate collected and consolidated solid waste and drummed waste from soil;

•	Off-site disposal of drummed materials, sludge, and other collected and consolidated waste
which contains substances, especially hazardous wastes, not suitable for on-Site containment;

•	Screen collected and consolidated solid waste materials for salvageable materials to be
decontaminated on-Site and taken off-Site for salvage;

•	Consolidate soil and non-salvageable solid waste which exceeds soil cleanup levels in the on-
Site containment area and cover with a Resource Conservation and Recovery Act (RCRA)
Subtitle C hazardous waste cap;

•	Bioremediate sediments in-place that exceed the cleanup levels for organic contaminants in the
seeps on the north slope of the Site, as necessary;

6


-------
•	Fence the Site to restrict Site access and place institutional controls (ICs) on Site to ensure the
integrity of the remedial action, including deed restrictions to prevent the installation of drinking
water wells and the disturbance of the capped area until cleanup levels are achieved;

•	Monitor groundwater and surface water/sediments to confirm that the removal, treatment, and
containment of source materials and the natural attenuation of residual contaminants allow for
the expeditious attainment of cleanup levels; and

•	Conduct other operation and maintenance (O&M) requirements, including cap mowing,
inspection, and repair.

The selected remedy is intended to protect human health and the environment by removing, treating, or
containing all significant threats at the Site, thereby reducing human health and environmental risks to
acceptable levels.

Status of Implementation

Construction of the selected remedy for the Site was completed in 2000. The PRPs performed the work
under Unilateral Administrative Order V-W-94-C-307 for remedial design and remedial action
(RD/RA), issued by EPA on August 16, 1994. During the RD, EPA approved a design modification to
stabilize the area to be capped to minimize shifting. Also, sediment and seep water sampling results
obtained during the RD indicated there was no need for bioremediation for seep sediments. Thus, EPA
eliminated the bioremediation for seep sediments from the design. Following these design changes,
construction of the remedy involved the following, as described in the EPA-approved Final Design
Report (GeoSyntec, 1999):

•	Construction of a slope buttress near the toe of the northeast slope of the area to be
capped;

•	Installation of a subsurface drainage system including geotextile filter, high-density
polyethylene (HDPE) piping, drainage gravel, and two concrete collection sumps;

•	Excavation and consolidation of impacted material in designated areas up-slope of the
buttress;

•	Construction of a final cap system over the consolidated, impacted material, consisting
of:

Placement, grading, and compaction of impacted material under the cap;

12 inches of bedding soil;

• 60-mil, HDPE geomembrane liner;

Geocomposite drainage layer;

18 inches of cover soil;

6 inches of topsoil; and

Establishment of a vegetative, grass cover.

9


-------
•	Installation of surface water management structures to manage run-on and run-off on and
around the cap. This included the installation of perimeter drainage ditches, intermediate
cover benches, and a buttress wall diversion ditch;

•	Implementation of erosion and sedimentation controls. In areas north, south, east, and
west of the cap, grading, seeding and mulching were conducted. Temporary silt fencing
was installed in these areas until the vegetation was established; and

•	Regrading and revegetation of disturbed areas of the slope.

Following completion of the RA, EPA issued a Preliminary Close-Out Report on July 7, 2000, to
document that RA construction activities were substantially completed (EPA, 2000).

Institutional Controls

ICs are non-engineered instruments, such as administrative and/or legal controls, that help minimize the
potential for exposure to contamination and protect the integrity of the remedy. Compliance with ICs is
necessary to assure long-term protectiveness for any areas which do not allow for UU/UE. EPA
conducted a review of the ICs in place and has determined that they are currently adequate to protect
human health and the environment. A summary of the implemented ICs for the Site is listed in Table 1
and are further discussed below. An IC map showing restricted areas at the Site is shown in Appendix B
- Figure 2.

Status of Access Restrictions and ICs:

Access restrictions, including a fence and warning signs are required per the 1994 ROD, and remain in
place. The following Site property real estate transactions were completed in 2021.

•	Attorneys representing Jack W. Longfellow notified EPA that their client purchased 5.164 acres
of the Site property from the Estate of Mr. Thomas Vandale (area). It should be noted this does
not include any of the RESTRICTED area. The EC on the subject parcel is referenced in the
Fiduciary Deed recorded by the Recorder of Washington County, Ohio, on September 28, 2021
(Vol 656 Pgs. 5855).

•	Attorneys representing Mr. Brian Carpenter and Mr. Richard E. Eddy notified EPA that their
clients purchased 25.55 acres of the Site property from the Estate of Mr. Thomas Vandale (area).
It should be noted that the RESTRICTED area was included in this transaction. The EC on the

11


-------
subject parcel is contained in the Corrective Deed filed for record by the Recorder of
Washington County, Ohio, on October 12, 2021 (Vol 657 Pgs. 2277).

Current Compliance:

Based on annual inspections by the City of Marietta and OEPA, along with discussions with the PRP
and OEPA, EPA is not aware of Site or media uses which are inconsistent with the stated objectives to
be achieved by the ICs. The remedy appears to be functioning as intended. No Site uses which are
inconsistent with the implemented ICs or remedy IC objectives were noted during the 4/27/2023 FYR
Site inspection.

IC Follow up Actions Needed:

No follow-up actions needed. In the 2019 FYR, EPA had considered relying on Ohio rules OAC Rules
3701-28-10(B) and (G) and OAC Rule 3745-27-13 to maintain protectiveness at the Site. Meanwhile,
EPA secured ECs with the new landowners to implement ICs for the Site. Since all ECs have been
recorded, reliance on the Ohio rules is no longer necessary to implement the ICs.

Long Term Stewardship:

Long-term protectiveness requires continued compliance with the ICs consisting of land use and
groundwater use restrictions to ensure that the remedy continues to function as intended. Long-term
stewardship (LTS) will ensure that the ICs are maintained, monitored and enforced. The 2019 Fourth
FYR recommended an update to the LTS Plan to address a process for dealing with any potential IC
issues that may arise during the reporting period. EPA continues to work with the PRP on finalizing
revisions to the LTS Plan.

Systems Operations/Operation & Maintenance

The PRPs are currently performing long-term O&M activities under EPA and State oversight. O&M
activities are being conducted in accordance with the 2001 Inspection, Maintenance, and Monitoring
Plan (IMMP), conditionally approved in 2001 and subsequently modified in 2012 (Addendum 1) and
2014 (Addendum 2) (Geosyntec, 2014). Final approval of the IMMP, as revised, was conditioned upon
receipt of a signed/recorded EC for the Site.

The 2001 IMMP requires the following activities to be performed:

•	Conduct annual inspections of the hazardous waste cover/cap and the other remedy components
and make repairs as needed;

•	Perform periodic (quarterly/semiannual/annual) groundwater, seep and surface water sampling,
and annual sediment sampling; and

•	Perform other activities as requested by EPA such as installing additional monitoring wells or
collecting additional samples.

The IMMP was updated in 2012 (Addendum 1) to include the following:

•	Reduced groundwater monitoring frequency from quarterly to annually at seven wells: MW01-
01, MW01-02, MW01-03, MW01-07, MW01-10, MW03-04 and MW03-12;

•	Continued quarterly groundwater monitoring at 7 wells: MW03-05, MW03-06, MW01-08,
MW03-09, MW03-11, MW07-13, andMW07-14;

12


-------
•	Reduced groundwater monitoring frequency from quarterly to annually for eight contaminants:
bis(2-ethylhexyl) phthalate, antimony, arsenic, barium, beryllium, cadmium, nickel and
vanadium;

•	Reduced groundwater monitoring frequency from quarterly to annually for monitored natural
attenuation (MNA) parameters (except groundwater stabilization parameters), dissolved
hydrocarbon gases and inorganic anions. Eliminate sulfate, sulfide, phosphate and ammonia
nitrogen from the monitoring program;

•	Reduced frequency of sediment and surface water monitoring from quarterly to annually, and
then from annually to every three years. Continue to monitor seeps annually at SW-06;

•	Specified annual sampling will be conducted during the second quarter sampling event;

•	Use passive diffusion bag (PDB) sampling for quarterly groundwater monitoring samples.
Groundwater samples collected during the annual sampling event (second quarter) will be
collected using low-flow sampling procedures. All groundwater samples collected from MW07-
13 will be collected using PDBs because low-flow groundwater sampling is not possible at
MW07-13; and

•	Reduced cap monument surveying from quarterly to annually and reinstituted quarterly surveys
if cap movement accelerates substantially.

In April 2014, the IMMP was further updated (Addendum 2) to include the following:

•	A requirement for evaluating MNA progress in meeting cleanup goals every five years;

•	Documentation and certification of existing ICs at the Site annually;

•	A requirement for a focused inspection and reporting of changes to land and groundwater use at
the Site; and

•	The reporting of any construction activities and vandalism that occurred between quarterly
monitoring events.

taking the following actions: 1) Complete two rounds of air and soil
gas sampling at the Site in accordance with the approved sampling
plan. If a complete VOC-contaminant VI exposure pathway exists at
the Site, determine whether VI of VOC-contaminants poses an
unacceptable risk to current or future residential users on the
uncapped portion of the Site. Based on the results, determine any

additional actions needed such as additional appropriate land use and
VI controls. 2) Finalize the draft supplemental risk assessment to
determine whether soils in the uncapped portion of the Site pose an
unacceptable risk to current or future residential users; based on the
results of the supplemental risk assessment, determine appropriate
additional soil response actions and/or restrictions, if any.

2021 FYR
Addendum:
1 (Sitewide)

Short-term Protective

The remedy at the Van Dale Junkyard Site currently protects human
health and the environment because there are no complete exposure
pathways. Based on the evaluation of indoor, ambient, and subsurface
soil gas sampling, a complete VI exposure pathway does not exist at
the Site and further analysis of surface and subsurface soil data
determined that soils on the uncapped portion of the Site do not pose
an unacceptable risk to current or future residential users. The single
onsite residence is connected to municipal water and ICs are
preventing the installation and use of groundwater onsite effectively.
Further, the cap at the Site is functioning as intended, is being well-
maintained, and there has been no evidence of trespassing or
vandalism. Annual Site reports provided by the PRPs certify that ICs
required by the 1994 ROD that are in place are maintained and
effective. However, in order for the remedy to be protective in the
long-term, the following actions need to be taken to ensure
protectiveness: Perform analysis and any necessary further sampling
investigations in accordance with the 1994 ROD and Inspection,
Maintenance and Monitoring Plan (IMMP) to determine the
effectiveness of the MNA remedy and if implementation of
contingency measures are needed; Update the HHRA to include the
following sentence regarding VI 'Should subsurface maintenance
work or construction activities be necessary in the future, an
evaluation of the potential risks along with a risk mitigation plan will
be implemented at that time'; and, Update the long-term stewardship
procedures in the IMMP to include how to address IC issues if
identified during an inspection.

IV. FIVE-YEAR REVIEW PROCESS

Community Notification, Involvement & Site Interviews

A public notice was made available on the EPA's website (https://www.epa.gov/oh/fifth-five-vear-
review-process-van-dale-iunkyard-site). on July 27, 2023, stating that there was a FYR and inviting the
public to submit any comments to EPA (See Appendix D). No comments were received. Because EPA is
in regular contact with OEPA and the PRP's consultant, interviews were not conducted. The results of
the review and the FYR report will be made available at the Site information repository located at the
Washington County Public Library, 615 Fifth Street, Marietta, Ohio, and on the Van Dale Junkyard
webpage at https://www.epa.gov/superfund/vandale-iunkyard

Data Review

Groundwater/Surface Water/Sediments

Groundwater: Groundwater monitoring is conducted in accordance with the Inspection, Maintenance
and Monitoring Plan (IMMP) (Geosyntec, 2001) and the 2012 addendum to the IMMP. Groundwater
monitoring is conducted quarterly. During the first, third and fourth quarters, groundwater samples are
collected from seven monitoring wells (MW03-05, MW03-06, MW01-08, MW03-09, MW03-11,
MW07-13, and MW07-14) using PDBs and analyzed for VOCs. During the second quarter, groundwater
samples are collected from monitoring well MW07-13 by PDB and analyzed for VOCs, and
groundwater samples are collected from the remaining 13 wells using low flow sampling and analyzed
for VOCs, bis(2-ethylhexyl)phthalate (BEHP), select metals, and MNA parameters.

An analysis of groundwater data from June 2018 through March 2023 was completed for this FYR.
Based on historic exceedances of CUGs, six COCs DCE, cis-l,2-Dichloroethylene (cis-DCE), trans-1,2-
Dichloroethene (trans-DCE), tetrachloroethylene (PCE), 1,1,1-Trichloroethane (TCA), and VC were
analyzed to determine statistical trend and time to meet CUGs. Of the 14 monitoring wells examined,
five had levels of one or more COC above their respective CUGs for the five-year period. These are the
same wells as the previous five-year review period (June 2013 - March 2018). These wells and COCs
are:

MW01- 08 (DCE, cis-DCE, PCE, and VC)

In monitoring well MW01-08 there were four COCs with values above their respective CUGs, three of
which had concentrations well above their respective CUGs (DCE, cis- DCE, and VC). DCE had a very

17


-------
strong downward trend and the possibility of meeting the CUG in 2033. cis-DCE had a weak to non-
existent downward trend with the possibly of meeting the CUG in 2062/2067. PCE is exhibiting a
downward trend, no seasonality, and, since June 2022, concentrations have been below the CUG. VC is
exhibiting a very strong downward trend, no seasonality, with the possibility of meeting the CUG at the
end of 2023 or in 2024.

MW01-10 (DCE, PCE, and VC)

Monitoring well MW01-10 had one COC, DCE, that appears to be exhibiting a weak, upward trend.
PCE appears to have met the CUG in 2019 and is currently stable, exhibiting no trend. VC is showing a
strong downward trend with concentrations at or below the CUG.

MW03-06 (DCE and VC)

In monitoring well MW-03-06, DCE concentrations are stable and were above the CUG only two
quarters during the period analyzed. VC concentrations are stable and were above the CUG only three
quarters during the period analyzed.

MW03-09 (DCE, cis-DCE, PCE, and VC)

Monitoring well MW03-09 had four COCs that were consistently or often higher than their respective
CUGs. DCE is stable with concentrations hovering just over the CUG. This contaminant currently
shows a slight downward trend with the possibility of meeting the CUG in 2064. cis-DCE was found to
not have a statistically significant trend or seasonality, but the concentrations observed fluctuate above
and below the CUG. PCE also shows no trend or seasonality, concentrations are stable but fluctuate just
over the CUG. VC, slightly elevated and stable, and has only exceeded the CUG three quarters over the
last five years.

MW03-11 (PCE and VC)

In well MW03-11 there are only two COCs, PCE and VC, with concentrations above the CUGs. PCE
concentrations, consistently greater than the CUG, are demonstrating a very strong downward trend
without seasonality, and may possibility meet the CUG by 2029 or 2030. VC slightly elevated and
stable, and has only exceeded the CUG three quarters over the last five years.

The complete EPA analysis can be found in Appendix E.

MNA Evaluation:

The IMMP, as revised, requires the groundwater data be used to evaluate the effectiveness of MNA
processes in attenuating remaining site contaminants to meet applicable CUGs under the ROD. This
MNA evaluation is required every five years, to coincide with EPA's FYRs. In its 2022 MNA
Efficacy Evaluation Report (See Appendix F), the PRPs provided the following conclusions and
recommendations:

•	Natural attenuation is occurring at varying rates due to the natural physical properties of the
aquifer matrix and the distribution of COCs at the Site. The continued presence of COCs in
groundwater is attributed to a secondary source of dissolved mass in the low permeability rock
matrix.

•	The attenuation over distance for all COCs, combined with the depletion of back-diffusion
contributions to the plume is resulting in the receding COC plume observed at the Site.

•	VOC concentrations are decreasing, as evidenced by plume shrinkage and receding source decay
rates, at an expected and acceptable rate given the fractured rock geology of the Site.

18


-------
•	Data show that the COCs are not migrating off-Site as evidenced by VOCs measured below the
ROD CUGs or non-detect in downgradient/side-gradient monitoring wells for at least the last
nine years.

•	It is recommended that continued monitoring be conducted in accordance with the IMMP and
subsequent IMMP addenda to confirm that VOC concentrations in the former source area are
continuing to decline.

EPA generally agrees with the conclusions and recommendations of the PRPs 2022 MNA Efficacy
Evaluation Report. Estimated time to reach CUGs, based on trend analysis of the data completed by
EPA, is largely consistent with the evaluation completed by the PRP. The timeline to achieve CUGs,
through MNA following source removal, was not modeled for the FS as part of the alternatives analysis,
but is expected to take at least 30 years.

VC 0.5	1.6-245	0.2 -0.5	0.3 - 1.0	0.3 - 1.0	.03 - 1.0

Surface Water and Sediments: The IMMP requires surface water and sediment monitoring on a triennial
basis (once every three years), and the surface water seep location annually. Surface water and sediment
samples were last collected in 2021. The surface water seep (SW-06) has not been sampled since 2017
due to insufficient water. Sediment and surface water sampling locations along Tributary A are co-
located at five locations (SW-01 thru SW-05 and SED-01 thru SED-05). Three additional locations
along Tributary A are monitored for sediments only (SED-06 thru SED-08).

The surface water samples were analyzed for five VOCs (1,1,1-TCA, 1,1-DCE, cis-l,2-DCE, PCE, and
trans-1,2-DCE). VOCs were not detected in any surface water samples. The surface water samples were
also analyzed for three metals: arsenic, cleanup level 48 ug/1; lead, cleanup level 3.2 ug/1; and silver;
cleanup level 0.12ug/l. These three metals were not detected above CUGs in any sample.

Eight sediment samples were analyzed for one VOC (PCE) and one SVOC (BEHP). PCE and BEHP
were not detected in any of the sediment samples. Sediment samples were also analyzed for three metals
(antimony, arsenic, and lead). Antimony was not detected in any of the sediment samples. Arsenic was
detected in all the sediment samples at concentrations exceeding the cleanup level (0.24 milligrams per
kilogram [mg/kg]). The concentrations of arsenic ranged from 7.97 mg/kg to 14.2 mg/kg. Lead was
detected in all sediment samples with concentrations ranging from 11.8 mg/kg to 68.3 mg/kg. Five of
the eight samples exceeded the cleanup level (15.9 mg/kg) for lead. These results are consistent with
historical sediment sampling results, except for the lead concentration at location SED-02. The

19


-------
concentration of lead at SED-02 (68.3 mg/kg) is higher than historic concentrations at this location,
which have ranged from 10.3 mg/kg to 28.6 mg/kg; however, given that lead concentrations in other
locations and in surface water samples are consistent with historic results, no action is required at this
time.

Site Inspection

The inspection of the Site was conducted on 4/27/2023. In attendance were Bill Murray, EPA RPM;
Baxter Foskuhl and Austin Tweedy, OEPA; and, Diane McCausland, Engineering Management, Inc.
The purpose of the inspection was to assess the protectiveness of the remedy. Based on observations, the
remedy appears to be functioning properly.

•	The cap, monitoring wells, gates, and fencing appeared to be in good condition;

•	All signs are in place and legible;

•	Survey markers for the cap monuments were readily visible;

•	No evidence of vandalism or trespassing was seen during the walking tour of the Site; and

•	No changes to land use were observed. It is still considered rural residential.

The site inspection checklist can be found in Appendix G.

V. TECHNICAL ASSESSMENT

QUESTION A: Is the remedy functioning as intended by the decision documents?

Answer: Yes.

Question A Summary:

The ROD required excavation and disposal (off-site and on-site) of source material, placement of a
RCRA Subtitle C hazardous waste cap over a 4-acre section of the Site, MNA to meet groundwater
CUGs, and ICs to ensure the integrity of the remedy is maintained. Observations made during the FYR
Inspection, completed April 27, 2023, indicated the cap was functioning as intended, was being well
maintained, and that there was no evidence of trespassing or vandalism at the Site.

Ten of the fourteen monitoring wells in the network exhibited contaminant concentrations at or below
their respective CUGs. MNA was expected to take a minimum of 30 years to achieve CUGs. The rate of
progress in attenuating, or estimated time to reach the CUGs, at two wells, MW01-08 and MW03-09,
could be 40 years (2064), based on current data trend analysis.

All ICs, in the form of ECs, have been implemented. All ECs are recorded and functioning properly. In
addition, a revision to the IMMP is being developed to include LTS procedures for addressing how
issues discovered during IC inspections will be addressed.

QUESTION B: Are the exposure assumptions, toxicity data, cleanup levels, and remedial action
objectives (RAOs) used at the time of the remedy selection still valid?

Answer: No

Question B Summary:

20


-------
The Maximum Contaminant Level (MCL) for cis-l,2-dichloroethene was revised to 70 ppb and the
current CUG at the Site is 100 ppb. The CUG no longer meets ARARs and must be revised to meet the
ARARs. EPA will work with the Office of Regional Counsel to revise or amend the enforcement
documents, as appropriate, to document and formalize the change to the CUG. This does not affect
current protectiveness, although, CUGs for cis-l,2-dichloroethene have not yet been attained at two
monitoring wells, and there is no current human exposure to contaminated groundwater.

Other than the change in MCL discussed above, the RAOs, exposure assumptions, and groundwater/soil
cleanup levels are still valid. In addition, soils in the uncapped portion of the site were evaluated in a
supplemental Human Health Risk Assessment (HHRA) completed in August 2019 based on a residential
use scenario that included potential risks from the VI exposure pathway, which was not evaluated during
the RI, and the evaluation indicated that there is no complete exposure pathway (Geosyntec, 2019).

Changes in Exposure Pathways

As indicated in the previous FYR (EPA, 2019), the ROD required contaminated soil in the uncapped
portion of the Site to be cleaned up to residential use. However, the 1999 post-excavation risk
assessment performed by the PRPs evaluated risks from soil in the uncapped area based on a hunting
and trespassing exposure scenario (3 x 10 6risk). The PRPs used this scenario because hunting and
trespassing were the current and reasonably anticipated future land use of the property at the time.
Approved by EPA in March 2020, the Supplemental HHRA Revision 4 included a complete surface and
subsurface soil evaluation, including: (i) development of a conceptual site model; (ii) data evaluation
and selection of constituents of potential concern; (iii) exposure assessment; (iv) toxicity assessment;
and (v) risk characterization. The Supplemental HHRA also included an evaluation of potential
exposures for current and future residents via the inhalation pathway on the uncapped portion of the
Site. Based on the evaluation of surface and subsurface soil in the uncapped portion of the Site, the
Supplemental HHRA concluded no unacceptable risk to current or future residential users. Based on the
evaluation of indoor, ambient, and subsurface soil gas, the Supplemental HHRA concluded no complete
VI exposure pathway exists on the uncapped portion of the Site.

Per and Polyfluoroalkyl Substances (PFAS) have been identified as emerging COCs in groundwater and
have been associated with a variety of industrial and municipal wastes that may have been disposed of at
Van Dale Junkyard. PFAS were not considered at the time of remedy selection. The PRP Group will
need to analyze for PFAS as potential emerging COCs in the groundwater in a future annual
groundwater sampling event. EPA anticipates this will occur in 2024 or 2025. Potential PFAS
contamination does not affect the current protectiveness of the remedy because all known contamination
is contained, and not migrating and effective ICs are in place. Furthermore, there is no one drinking or
using the water downgradient of the landfill and there are no municipal water supply wells within the
immediate vicinity of the Site, so if PFAS is found to be present there is no complete exposure pathway.

1,4-Dioxane has also been identified as emerging COC in groundwater and has been associated with a
variety of industrial and municipal wastes that may have been disposed of at Van Dale Junkyard. 1,4-
Dioxane was not considered at the time of remedy selection. The PRP Group will need to analyze for
1,4-Dioxane as a potential emerging COC in the groundwater in a future annual groundwater sampling
event. EPA anticipates this will occur in 2024 or 2025. Potential 1,4-Dioxane contamination does not
affect the current protectiveness of the remedy because all known contamination is contained, and not
migrating and effective ICs are in place. Furthermore, there is no one drinking or using the water
downgradient of the landfill and there are no municipal water supply wells within the immediate vicinity
of the Site, so if 1,4-Dioxane is found to be present there is no complete exposure pathway.

21


-------
QUESTION C : Has any other information come to light that could call into question the protectiveness
of the remedy?

Answer: No
Question C Summary:

Based on information available (e.g., State/PRP reports, site inspections, etc.), there have been no
impacts from natural disasters, no newly identified ecological risks, or any other information that has
been identified that could affect the protectiveness of the remedy for the Site.

OTHER FINDINGS

In addition, the following issues and recommendations were identified during the FYR, but do not affect
current protectiveness:

•	The Maximum Contaminant Level (MCL) for cis-l,2-dichloroethene was revised to 70 ppb and
the current CUG at the Site is 100 ppb. The CUG no longer meets ARARs and must be revised
to meet the ARARs. EPA will work with the Office of Regional Counsel to revise or amend the
enforcement documents, as appropriate, to document and formalize the change to the CUG. This
does not affect current protectiveness, although CUGs for cis-l,2-dichloroethene have not yet
been attained at two monitoring wells, there is no current human exposure to contaminated
groundwater.

•	The 1994 ROD prescribed in place bioremediation of sediments found in the seeps on the north
slope. Sediment and seep water sampling results obtained during the RD indicated there was no
need for bioremediation for seep sediments and EPA eliminated the bioremediation for seep

23


-------
sediments from the design. Formal documentation of this decision cannot be found. EPA will
include this decision in the documentation of the above CUG change for cis-l,2-dichloroethene

VII. PROTECTIVENESS STATEMENT

OU1 and Sitewide Protectiveness Statement

Protectiveness Determination:

Short-term Protective

Protectiveness Statement: The remedy at the Site currently protects human health and the environment
because there are no complete exposure pathways and is functioning as intended. Although, cleanup
goals have not yet been attained in groundwater, there is no current human exposure to contaminated
groundwater. The single onsite residence is connected to municipal water. Effective ICs are in place
and there is no one drinking or using the water downgradient of the landfill and there are no municipal
water supply wells within the immediate vicinity of the Site. Further, the cap at the Site is functioning
as intended, is being well-maintained, and there has been no evidence of trespassing or vandalism.
Annual Site reports provided by the PRPs certify that ICs required by the 1994 ROD that are in place
are maintained and effective.

However, in order for the remedy to be protective in the long-term, the following actions need to be
taken to ensure protectiveness: Groundwater must be sampled and analyzed for PFAS and 1,4-dioxane;
LTS procedures in the IMPP must be updated to include how to address issues if identified during an
inspection; and EPA must continue to complete multiple statistical analyses of the groundwater
monitoring data to ensure effectiveness of the MNA remedy.

VIII. NEXT REVIEW

The next FYR report for the Van Dale Junkyard Superfund Site is required five years from the
completion date of this review.

("ORC") §§ 5301.80 to 5301.92 for the purpose of subjecting the Restricted Area (described
below) to the activity and use limitations and to the rights of access described below.

I. BACKGROUND

1.	Pursuant to Section 105 of the Comprehensive Environmental Response, Compensation
and Liability Act ("CERCLA"), 42 U.S.C. § 9605, the United States Environmental Protection
Agency ("U.S. EPA") placed the Vandale Junkyard Site ("Site"), located at Marietta Township
Road No. T-83, in Washington County, Ohio, on the National Priorities List, set forth in 40
C.F.R. Part 300, Appendix B, by publication in the Federal Register. 51 Fed. Reg. 21,078 (June
10, 1986).

2.	U.S. EPA issued a Record of Decision (ROD) on March 31, 1994, providing for, among
other things, consolidating wastes and placing a multi-layer cover over hazardous substances and

wastes remaining at the Site, minimizing the potential for direct contact with hazardous
substances and minimizing releases from the Site; continuing to operate and maintain the remedy
after the remedy is constructed; continuing to monitor the Site and surrounding area for any
potential releases including releases to the surface waters, sediments, and groundwater, the soils
and the air; imposing Site security requirements at and near the covered wastes and substances,
and; requiring institutional controls for the Site area through deed restrictions and/or zoning.
The institutional controls, which are addressed more specifically in this document, are to protect
the performance of the remedy and prevent the exposure of humans or the environment to
contaminants, by limiting the future use of the property at and near where remedial construction
has occurred, and by limiting future uses that may interfere with maintaining or monitoring the
performance of the remedy. Ohio EPA concurred with the ROD.

3.	On August 16, 1994 and October 16, 1995, U.S. EPA issued Unilateral Administrative
Orders ("UAO"). In the Matter of: The Vandale Junkvard Site. Case Nos. V-W-94-C-307

and, Unisys Corporation, (collectively the "Performing Respondents") and Mr. Thomas Vandale
as a cooperating Respondent, ordering them to implement the remedial actions selected in the

Owners are the sole owners of the Restricted Area; that Owners hold fee simple title to the
Restricted Area which is free, clear and unencumbered; that the Owners have identified ail other
persons that own an interest in or hold an encumbrance on the Property and notified such persons
of the Owner's intention to enter into this Environmental Covenant; that Owners have the power
and authority to make and enter into this Environmental Covenant as Owners and Holders, to
grant the rights and privileges provided here and to carry out all obligations of Owners and
Holders in this Environmental Covenant; that this Environmental Covenant has been executed
and delivered pursuant to the UAOs; and, that this Environmental Covenant will not materially
violate or contravene or constitute a material default under any other agreement, document or
instrument to which Owners are parties or by which Owners may be bound or affected.

b.	Right to Enforce Environmental Covenant Against Owners; Equitable Remedies.
In the event that Owners or any other person should attempt to deny the rights of access granted
under Section IV or should violate the restrictions on activities and uses of the Restricted Area
set forth in Section V, then, in addition to any rights which U.S. EPA may have under the UAOs,
U.S. EPA, Ohio EPA or any Performing Respondent that is adversely affected by each denial
(for example, any Performing Respondent that is prevented from conducting its remedial
obligations under the UAO or the ROD) or by such violation shall have the right to immediately
seek an appropriate equitable remedy and any court having jurisdiction is hereby granted the
right to issue a temporary restraining order and/or preliminary injunction prohibiting such denial
of access, activity or use in violation of restrictions, upon application by U.S. EPA, Ohio EPA or
by such adversely affected Performing Respondent without notice or posting bond. Owners and
each subsequent owner of an interest in the Restricted Area by accepting a deed to the Restricted
Area or to any part of it waives all due process or other constitutional right to notice and hearing
before the grant of a temporary restraining order and/or preliminary injunction pursuant to this
Subsection 25.(b).

c.	Future Cooperation; Execution of Supplemental Instruments. Owners agree to
cooperate fully with U.S. EPA, Ohio EPA and the Performing Respondents, to assist them in
implementing the rights granted them under this Environmental Covenant and, in furthering this
Environmental Covenant, agree to execute and deliver such further documents as may be
requested by U.S. EPA to supplement or confirm the rights granted hereunder.

d.	Cumulative Remedies; No Waiver. All of the rights and remedies set forth in this
Environmental Covenant or otherwise available at law or in equity are cumulative and may be
exercised without regard to the adequacy of, or exclusion of, any other right, remedy or option
available here or under the UAOs or at law. The failure to exercise any right granted here, to
take action to remedy any violation by Owners of the terms here, or to exercise any remedy
provided here, shall not be deemed to be a waiver of any such right or remedy and no
forbearance on the part of U.S. EPA and no extension of the time for performance of any
obligations of Owners shall operate to release or in any manner affect U.S. EPA's rights.

e.	Severability. If any provision of this Environmental Covenant is found to be
unenforceable in any respect, the validity, legality, and enforceability of the remaining
provisions shall not in any way be affected or impaired.

f.	Recordation. Within thirty (30) days after the date of the final required signature
on this Environmental Covenant, Owners shall file this Environmental Covenant for recording,

To be recorded with Deed
Records - ORG § 317.08

ENVIRONMENTAL C OVENANT

uk

This Environmental Covenant is made as of the 7 _ day of November, 2018, by and
among Margie Longfellow and Margie M. Pugh, acting in their capacity as Co-Executors on behalf
of the Estate of Thomas Vandale, deceased Owner and Holder, and U.S. EPA (as further identified
below) pursuant to Ohio Revised Code ("GRC") §§ 5301.80 to 5301.92 for the purpose of
subjeeting the Property and the Restricted Area (described below) to the activity and use
limitations and to the rights of access described below. This Environmental Covenant will also
provide rights of access to property ("Access Property" as further described below) containing
roads to the Site, the Property and the Restricted Area as specified in Paragraph 23.

I- BACKGROUND

1.	Pursuant to Section 105 of the Comprehensive Environmental Response, Compensation
and Liability Act ("CERCLA"), 42 U.S.C. § 9605, the United States Environmental Protection
Agency ("U.S. EPA") placed the Vandale Junkyard Site ("Site"), located at Marietta Township
Road No. T-83, in Washington County, Ohio, on the National Priorities List, set forth in 40 C.F.R.

Part 300, Appendix B, by publication in the Federal Register, 51 Fed. Reg. 21,078 (June 10,1986).
The Property that is subject to this Environmental Covenant is part of the Site.

2.	A Remedial Investigation/Feasibility Study (RI/FS) of the Site history found that Mr.
Vandale operated the Site as a junkyard from the early 1960s until about 1980, and that junkyard
operations may have been occurring at the Site since the 1940s. During its operation, the junkyard
received a variety of materials for disposal and/or salvage, including general wastes such as scrap
metal, appliances, furniture, automobiles, tires and batteries. In addition, disposal records from
various industrial facilities indicate that the Site accepted at least 2200 drums of industrial wastes
in the late 1970s. These drums contained materials such as waste industrial solvents, tar and iron


-------
cakes, sludges, paints and inks. The investigation determined that unsalvageablc materials were
managed at the Site either by emptying them onto the ground, burning them on the ground, and/or
burying or bulldozing them over the Site.

3.	The RI/FS found widespread organic and inorganic hazardous substances in soils,
groundwater, surface waters, and sediments at the Site. Analysis of Site soil samples demonstrated
high concentrations of hazardous substances, including chlorinated compounds tetrachloroethene
and trichloroethene; unchlorinated compounds typically associated with gasoline (benzene,
ethylbenzene, toluene, and xylenes); bis(2-ethylhexyl) phthalate; polycyclic aromatic
hydrocarbons; and a number of metals. Analysis of on-Site groundwater samples exhibited a
number of hazardous substances at levels in excess of established drinking water standards, the
U.S. EPA's Maximum Contaminant Levels (MCLs). On-Site ground water samples indicated
MCI, exceedances for 1,1-dichloroethcne; 1,2-dichloroethene; 1.1,1-trichlorocthane;
tetrachloroethene; trichloroethene; vinyl chloride; arsenic; barium; beryllium; cadmium;
chromium; lead; nickel; and thallium. Analysis of surface waters and seeps which drain from the
Site were found to contain hazardous substances at levels in excess of Ohio Water Quality
Standards (WQS) and U.S. EPA Ambient Water Quality Criteria (AWQC) at a number of
sampling locations. WQS and AWQC were exceeded for the following substances: silver,
cadmium, copper, cyanide, iron, lead, mercury, nickel, selenium, and zinc. Sediments in these
surface waters also reflected many of these same metals.

4.	The RI/FS found that hazardous substances found at the surface and buried at the Site were
presenting a direct contact threat. Surface water drainage from the Site flows through two
intermittent streams to Duck Creek, a small tributary to the Ohio River located less than one quarter
mile to the west of the Site. Although saturated bedrock formations exist below the Site as
identified in the Site Conceptual Model, the nature of the mantle covering the bedrock formations
beneath the Site allows only marginally interconnected pockets of groundwater. At present, there
is no known use of groundwater at the Site.

5.	U.S. EPA issued a Record of Decision (ROD) on March 31, 1994, providing for, among
other things, consolidating wastes and placing a multi-layer cover over hazardous substances and
wastes remaining at the Site, minimizing the potential for direct contact with hazardous substances
and minimizing releases from the Site; continuing to operate and maintain the remedy after the
remedy is constructed; continuing to monitor the Site and surrounding area for any potential
releases including releases to the surface waters, sediments, and groundwater, the soils and the air;
imposing Site security requirements at and near the covered wastes and substances, and; requiring
institutional controls for the Site area through deed restrictions and/or zoning. The institutional
controls, which are addressed more specifically in this document, are to protect the performance
of the remedy and prevent the exposure of humans or the environment to Site-related compounds
of concern by limiting the future use of the property at and near where remedial construction has
occurred, and by limiting future uses that may interfere with maintaining or monitoring the

2


-------
performance of the remedy. Ohio EPA concurred with the ROD.

6.	On August 16, 1994 and October 16, 1995, U.S. EPA issued Unilateral Administrative
Orders ("UAO"), In the Matter of: The Vandale Junkyard Site, Case Nos. V-W-94-C-307 (August
16,1994) and V-W-96-C-318 (October 16,1995) (collectively, "UAOs")to Goodrich Corp., Cytec
Industries Inc., Kardex Systems, Inc., Lockheed Martin Corp., Exxon Mobil Corp., and, Unisys
Corporation, (collectively the "Performing Respondents") and Mr. Thomas Vandale as a
cooperating Respondent, ordering them to implement the remedial actions selected in the March
31, 1994 ROD. Any operation, maintenance and monitoring activities related to implementing the
remedial actions, such as those described in Paragraph 24, are enforceable under the UAOs and
ROD.

7.	With the exception of the institutional controls, and operation, maintenance and monitoring
of the remedy, the remedial action has been implemented at the Site.

II. STATEMENT OP AUTHORITY AND PURPOSE

8.	Environmental Covenant. This instrument is an environmental covenant executed and
delivered pursuant to §§ 5301.80 to 5301.92 of the Ohio Revised Code. U.S. EPA by issuing the

ENVIRONMENTAL COVENANT

This Environmental Covenant is made as of the day Qf June? 2020, by and among
Jack Longfellow, Owner and Holder, and U.S. EPA (as further identified below) pursuant to Ohio
Revised Code ("ORC") §§ 5301.80 to 5301.92 for the purpose of subjecting the Property to the
activity and use limitations and to the rights of access described below.

I. BACKGRQUND

1.	Pursuant to Section 105 of the Comprehensive Environmental Response, Compensation
and Liability Act ("CERCLA"), 42 U.S.C. § 9605, the United States Environmental Protection
Agency ("U.S. EPA") placed the Vandale Junkyard Site ("Site"), located at Marietta Township
Road No. T-83, in Washington County, Ohio, on the National Priorities List, set forth in 40 C.F.R.
Part 300, Appendix B, by publication in the Federal Register. 51 Fed. Reg. 21,078 (June 10,1986).
The Property that is subject to this Environmental Covenant is part of the Site.

2.	A Remedial Investigation/Feasibility Study (RI/FS) of the Site history found that the Site
was operated as a junkyard from the early 1960s until about 1980, and that junkyard operations
may have been occurring at the Site since the 1940s. During its operation, the junkyard received
a variety of materials for disposal and/or salvage, including general wastes such as scrap metal,
appliances, furniture, automobiles, tires and batteries. In addition, disposal records from various
industrial facilities indicate that the Site accepted at least 2200 drums of industrial wastes in the
late 1970s. These drums contained materials such as waste industrial solvents, tar and iron cakes,
sludges, paints and inks. The investigation determined that unsalvageable materials were managed
at the Site either by emptying them onto the ground, burning them on the ground, and/or burying
or bulldozing them over the Site.

WASHINGTON COUNTY AUDITOR




-------
3.	The RI/FS found widespread organic and inorganic hazardous substances in soils,
groundwater, surface waters, and sediments at the Site. Analysis of Site soil samples demonstrated
high concentrations of hazardous substances, including chlorinated compounds tetrachloroethene
and trichloroethene; unchlorinated compounds typically associated with gasoline (benzene,
ethylbenzene, toluene, and xylenes); bis(2-ethylhexyl) phthalate; polycyclic aromatic
hydrocarbons; and a number of metals. Analysis of on-Site groundwater samples exhibited a
number of hazardous substances at levels in excess of established drinking water standards, the
U.S. EPA's Maximum Contaminant Levels (MCLs). On-Site ground water samples indicated
MCL exceed ances for 1,1-dichIoroethene; 1,2-dichloroethene; 1,1,1 -trichloroethane;
tetrachloroethene; trichloroethene; vinyl chloride; arsenic; barium; beryllium; cadmium;
chromium; lead; nickel; and thallium. Analysis of surface waters and seeps which drain from the
Site were found to contain hazardous substances at levels in excess of Ohio Water Quality
Standards (WQS) and U.S. EPA Ambient Water Quality Criteria (AWQC) at a number of
sampling locations. WQS and AWQC were exceeded for the following substances: silver,
cadmium, copper, cyanide, iron, lead, mercury, nickel, selenium, and zinc. Sediments in these
surface waters also reflected many of these same metals.

4.	The RI/FS found that hazardous substances found at the surface and buried at the Site were
presenting a direct contact threat. Surface water drainage from the Site flows through two
intermittent streams to Duck Creek, a small tributary to the Ohio River located less than one quarter
mile to the west of the Site. Although saturated bedrock formations exist below the Site as
identified in the Site Conceptual Model, the nature of the mantle covering the bedrock formations
beneath the Site allows only marginally interconnected pockets of groundwater. At present, there
is no known use of groundwater at the Site.

5.	U.S. EPA issued a Record of Decision (ROD) on March 31,1994, providing for, among
other things, consolidating wastes and placing a multi-layer cover over hazardous substances and
wastes remaining at the Site, minimizing the potential for direct contact with hazardous substances
and minimizing releases from the Site; continuing to operate and maintain the remedy after the
remedy is constructed; continuing to monitor the Site and surrounding area for any potential
releases including releases to the surface waters, sediments, and groundwater, the soils and the air;
imposing Site security requirements at and near the covered wastes and substances; and requiring
institutional controls for the Site area through deed restrictions and/or zoning. The institutional
controls, which are addressed more specifically in this document, are to protect the performance
of the remedy and prevent the exposure of humans or the environment to Site-related compounds
of concern by limiting the future use of the Property at and near where remedial construction has
occurred, and by limiting future uses that may interfere with maintaining or monitoring the
performance of the remedy. Ohio EPA concurred with the ROD.

6.	On August 16, 1994 and October 16, 1995, U.S. EPA issued Unilateral Administrative
Orders ("UAO"), In the Matter of: The Vandale Junkvard Site. CaseNos. V-W-94-C-307 (August

2


-------
16,1994) and V-W-96-C-318 (October 16,1995) (collectively, "UAOs") to Goodrich Corp., Cytec
Industries Inc., Kardex Systems, Inc., Lockheed Martin Corp., Exxon Mobil Corp., and, Unisys
Corporation, (collectively the "Performing Respondents") and Mr, Thomas Vandale as a
cooperating Respondent, ordering them to implement the remedial actions selected in the March
31, 1994 ROD. Any operation, maintenance and monitoring activities related to implementing the
remedial actions, such as those described in Paragraph 22, ire enforceable under the UAOs and
ROD.

7. With the exception of the Institutional controls, and operation, maintenance and monitoring
of the remedy, the remedial action has been implemented at the Site.

8.	Environmental Covenant. This instrument is an environmental covenant executed and
delivered pursuant to §§ 5301.80 to 5301.92 of the Ohio Revised Code. U.S. EPA by issuing the
ROD, and Ohio EPA by concurring in the ROD, have "determined or approved the environmental
response project," under Section 5301.80 of the Ohio UECA statute. The UAOs constitute an
environmental response project as defined by ORC §5301.80(E) and authorize and require certain
remedial actions be performed.

9.	Access to. and Activity and Use Limitations at. the Property. In executing this
Environmental Covenant, Jack Longfellow, the Owner, agrees: 1) to grant a permanent right of
access over the Property to the Access Grantees (as defined in this document) for purposes of
implementing, facilitating, monitoring, and maintaining the remedial action for the Vandale
Junkyard Superfund Site, and 2) to impose on the Property activity and use limitations as covenants

Summary

Fifth Five-Year Review in Process

U.S. EPA is conducting a five-year review of the Van Dale Junkyard site located on Goose
Run Road, between Township Road 345 and State Route 26 in Marietta, Ohio. The
Superfund law requires regular checkups of sites that have been cleaned up - with
waste managed on-site - to make sure the cleanup continues to protect people and the
environment. This is the fifth five-year review of this site.

EPA's cleanup at the site consisted of installing a hazardous waste cover, or cap;
excavating approximately 9,000 cubic yards of contaminated material from the site for
either off-site disposal or for on-site containment under a hazardous waste cap; and
monitored natural attenuation.

More information is available at the Washington County Public Library, 615 Fifth St, and
at the Van Dale Junkyard webpage. The review is expected to be completed by February
2024.

The five-year review is an opportunity for you to tell EPA about site conditions and any
concerns you have.

Trend Analysis of Six Chemicals of Concern in the Groundwater
at the Vandale Junkyard Superfund Site
June 2018 through March 2023

USEPA FIELDS Group

John Canar, Environmental Scientist
Chuck Roth, Life Scientist
Tyler Vappi, Research Associate

Introduction

In preparation for the upcoming five-year review, selected groundwater chemical concentrations were
evaluated for the most recent five-year period at the Vandale Junkyard site. Groundwater sampling at
the Vandale Junkyard Superfund site is conducted quarterly or annually, depending on the well.
Groundwater data in the USEPA Region 5 EQuIS database exist from June 2001 to the present. The
five-year period selected for the below analyses was June 2018 through March 2023. This document
includes analyses performed on six chemicals of concern in the groundwater at the site for this time
period. These chemicals were: 1,1-Dichloroethene (DCE), cis-l,2-Dichloroethylene (cis-DCE), trans-
1,2-Dichloroethene (trans-DCE), tetrachloroethylene (PCE), 1,1,1-Trichloroethane (TCA), and vinyl
chloride (VC). Basic statistics and trend analysis were conducted on the six chemicals of interest in
each of the 14 wells for the selected five-year period and are presented in this document.

Summary of Significant Findings

Of the 14 monitoring wells examined, five had levels of one or more chemicals of interest significantly
above their respective cleanup goals (CUGs) for the five-year period (June 2018 - March 2023). The
same wells as in the previous five-year review (June 2013 - March 2018). These wells were: MW01-
08, MW01-10, MW03-06, MW03-09, and MW03-11.

MW01-08:

•	the medians for cis-DCE, DCE, PCE, and VC were 7, 32, 1.3, and 172 times higher than their
respective CUGs. (Previously 9, 45, 3, and 276 times higher.)

•	cis-DCE had a weak to non-existent downward trend, possibly meeting the CUG in 2062/2067.

2


-------
(Previously, also a weak to non-existent trend.)

•	DCE had a very strong downward trend, possibly meeting the CUG in 2033, however DCE
concentrations began to plateau at the end of 2020, roughly at 40ppb. (Previously, an upward
trend.)

•	PCE had a downward trend and, since, June 2022, the levels were below the CUG. (Previously,
no trend.)

•	VC had a very strong downward trend, possibly meeting the CUG at the end of 2023 or in 2024,
however VC concentrations may be plateauing near 50ppb. (Previously, VC data were plateauing
around 127ppb.)

MW01-10:

•	the median for DCE was 1.2 times higher than its CUG. (Previously, DCE, PCE, and VC were 3,
5, and 1.5 times higher.)

•	DCE had a very weak upward trend, hence unlikely to meet the CUG in the future. (Previously,
no trend.)

•	PCE met the CUG in 2019 and currently has no trend. (Previously, there was a strong downward
trend and expectation to meet the CUG between 2019 and 2022.)

•	VC had a strong downward trend and all values were at or below the CUG. (Previously, no
trend.)

MW03-09:

•	the medians for cis-DCE, DCE and PCE were 0.7, 4, and 8 times higher than their respective
CUGs. (Previously, 1.1, 9, and 14 times higher.)

•	cis-DCE had no trend but linear regression and Sen's slope method predicts that the well will be
above the CUG in 2029/2030. (Previously, no trend.)

•	DCE had no trend but linear regression predicts possibly meeting the CUG in 2064, whereas
Sen's slope method predicts an increasing trend. (Previously, no trend.)

•	PCE had no trend but linear regression predicts possibly meeting the CUG in 2044, whereas Sen's
slope method predicts an increasing trend. (Previously, a weak upward trend.)

MW03-11:

•	the median for PCE was 7 times higher than its CUG. (Previously, 11 times higher.)

•	PCE had a very strong downward trend, possibly meeting the CUG in 2029/2030, however
concentrations have been plateauing around 9ppb over the past two years. (Previously, there was
a strong downward trend but the last 1-1.5 years of PCE data were plateauing at a median of
13ppb.)

Methods

Data

The USEPA Region 5 EQuIS database was queried for six chemicals of interest: DCE, cis-DCE, trans-
DCE, PCE, TCA, and VC. These chemicals were queried from the fourteen wells (see Figure 1) with
chemistry data for the time period of interest, June 2018 through March 2023. The selected time period
ensured that five years of annual or quarterly data were analyzed and complemented the previous five-
year review of June 2013 through March 2018 groundwater data.

Specifically, in EQuIS, the "Analytical Results II" query ("report" in EQuIS jargon) was used for the
above query with the following modifications:

•	all monitoring wells were queried

•	field duplicates as well as the default "normal" samples were queried

•	the date range was 6/1/2018 through 3/31/2023

•	only the groundwater sample matrix was queried

•	only the above six chemicals were queried

•	additional well information was also queried, e.g., surface elevation, well start depth
Data Handling and Basic Statistics

The output from the above EQuIS query, a comma-separated file (*.csv), was imported into the SAS
statistical software for data "cleanup", formatting, new field creation, subsetting, basic statistics,
graphing, and exporting for use in other software (ArcGIS Pro, ProUCL, and VSP). Two of the wells
had field duplicates, wells MW01-08 and MW03-09. SAS was used to create a maximum value from
these field duplicates in order to be most conservative, from an ecological and human health standpoint.
Historically, the consultants for Vandale Junkyard (Engineering Management, Inc. EMI) selected the
"parent" sample ID in the case of any duplicate samples and used that value for statistical analysis. (The
"parent" sample ID is that sample not identified as the duplicate.)

Reporting limits and Cleanup Goals

One concern with the existing data is the use of reporting limits at or very close to the cleanup goal
(CUG). In the case of VC, the reporting limit is at the CUG of 0.5ppb. Hence it will not be possible to
demonstrate that the VC levels in these wells were below the CUG; only that they were at the CUG.

Upgradient compared to Downgradient wells

Graphic comparisons of the six chemicals of interest in selected up- and down-gradient wells were
generated in the SAS statistical software.

Maps of Chemical concentrations by well

ArcGIS was used to create maps of the maximum concentration level for each of the 14 wells and each
of the six chemicals of interest for the period June 2018 through March 2023.

Trend Analysis and Time to Meet Cleanup Goals (CUGs)

A Python script was integrated with ArcGIS Pro to perform the Mann-Kendall nonparametric test for
trend. (The Python scripts' Mann-Kendall results matched those found from ProUCL version 5.1.) The
Theil-Sen trend test was performed in ProUCL version 5.1. And, Visual Sample Plan (VSP) version
7.19 was used to perform the Season-Kendall trend test. The Seasonal-Kendall is "an extension of the
Mann-Kendall" test when "the data collected over time were expected to change in the same direction
(up or down) for one or more seasons" (VSP, 2018). Both softwares were funded, in part, by the U.S.
EPA and other Federal agencies.

The time required to meet a cleanup goal (CUG) for selected wells and chemicals was calculated using
equations for trend estimated in the VSP software and confirmed in the ProUCL software. Both
softwares estimate trend equations using linear regression methods and nonparametric regression
methods (i.e., nonparametric methods Theil-Sen in ProUCL and Sen's slope estimation in VSP).

Results and Conclusions

Data characteristics and Basic Statistics

Most of the 14 wells had a very high proportion of non-detects for the six chemicals of interest. For
example, wells MW03-04, MW03-12, MW07-13, and MW07-14 had non-detects for all six chemicals
for every sampling event, hence 100% non-detects. Another six wells (MW01-01, MW01-02, MW01-
03, MW01-07, MW03-05, and MW03-06) had from 68 to 93% non-detects for all six chemicals. Due to
the larger proportion of non-detects or very narrow ranges of concentrations, trend analysis was not
conducted on many of the chemicals of interest for these wells, save for VC levels. Additionally, trend
analysis was performed for MW03-06 for DCE and VC, MW03-11 for PCE and VC, MW03-12 for PCE
and VC, and MW07-13 for DCE and VC. (See Table 1 for an overview of the trend results as well as
basic statistics for the 14 wells.)

Basic statistics were performed in the SAS statistical software. The results are presented in Table 1 and
Table 2.

Upgradient compared to Downgradient wells

Four upgradient versus downgradient well pairings were compared (see Figure 2). Well MW03-11 was
compared to the two downgradient wells, MW07-13 and MW07-14 (Figures 3-8), one of the six
chemicals, PCE, had almost always consistently higher levels than either of the downgradient wells (see

5


-------
Figure 5). Additionally, the downward trend can be seen in this figure. Vinyl chloride, although having
three concentrations higher than the CUG, had the same concentrations in each of the three wells over
time (see Figure 8). Four of the six chemicals (cis-DCE, DCE, TCA, and trans-DCE) in MW03-11 were
well below the respective cleanup goals (CUGs).

For MW03-09 compared to the two downgradient wells, MW01-07 and MW03-12 (Figures 9-14), four
of the six chemicals (cis-DCE, DCE, PCE, and VC) had higher or sometimes higher levels in the
upgradient (MW03-09) well than the downgradient wells MW01-07 and MW03-12. Three of these four
chemicals were often above their respective cleanup goals (cis-DCE, see Figure 9) or were well above
their CUGs (DCE and PCE, see Figures 10 and 11). Vinyl chloride, although having three
concentrations higher than the CUG, had the same concentrations in each of the three wells over time
(see Figure 14). The other, TCA, had levels well below its CUG of 20ppb.

Well MW01-08 contained concentration levels all six chemicals well above, or mostly so, than those
found in the downgradient well MW03-12 (Figures 15-20). Chemicals cis-DCE, DCE, PCE, and VC
were well above, or mostly so, then their respective CUGs (see Figures 15, 16, 17, and 20). Since June
2022, PCE levels have been below its CUG of 1.5ppb (see Figure 17). cis-DCE may meet its CUG in
2062/2067. DCE and VC may meet their CUGs in 2033 and 2024, respectively, but each appears to be
plateauing at about 40ppb and 50ppb, respectively (see Figures 16 and 20). TCA and trans-DCE were
well below their respective CUGs in both the up- and downgradient wells (see Figures 18 and 19).

Three of the chemicals in well MW01-10 were higher than those in well MW03-05 (see Figures 21-26).
These chemicals were cis-DCE, DCE, and PCE (see Figures 21, 22, and 23). The other three chemicals
in well MW01-10 were very close to their respective chemical concentrations in well MW03-05. DCE
and PCE levels in well MW01-10 were sometimes above their respective CUGs, but not by a lot (see
Figures 22 and 23). Vinyl chloride, although having three concentrations higher than the CUG, it had
the same concentrations or lower than the downgradient well, MW03-05 (see Figure 26).

Maps of Chemical concentrations by well

Maps of the maximum concentration level for each of the 14 wells and each of the six chemicals of
interest for the period June 2018 through March 2023 are shown in Figures 27-32. The lowest range of
concentration values in the legend of each figure represents each chemical's cleanup goal (CUG). As in
the previous five-year analysis, four of the six chemicals of interest had levels above their respective
cleanup goals: cis-DCE, DCE, PCE, and VC (see Figures 27-29 and 32). Only one well, MW01-08 had
a cis-DCE level above the CUG (see Figure 27). Four wells, MW01-08, MW01-10, MW03-06, and
MW03-09 had DCE levels above their CUGs (see Figure 28). Four wells, MW01-08, MW01-10,
MW03-09, and MW03-11 had PCE levels above their CUGs (see Figure 29). Seven of the 14 wells had
VC levels above their CUGs. These wells were: MW01-08, MW03-05, MW03-06, MW03-09, MW03-
11, MW07-13, and MW07-14. Each had VC levels above their CUGs (see Figure 32). Taken as a
whole (see Figure 33), there were eight wells with one or more chemicals of concern with a maximum
value above their respective CUGs. These wells were: MW01-08, MW01-10, MW03-05, MW03-06,
MW03-09, MW03-11, MW07-13, and MW07-14. The four downgradient wells, MW03-05, MW03-06,

6


-------
MW07-13 and MW07-14 only had VC levels above the CUG, however each had some VC
concentrations with non-detect values of lppb, very close to the CUG of 0.5ppb.

Another way to show the elevated levels of the six chemicals of interest in these four upgradient wells is
displayed in Table 2. This table provides descriptive statistics for the chemicals of interest in each well
(number of observations, median, and range) as well as the proportion of samples at or above the
cleanup goal (see column "2018-2023 Prop, ge CUG" in Table 2). This field, "Prop, ge CUG", is a
measure of the consistency of exceedances. As seen in the table, the majority of wells with exceedances
had them at very high proportions, e.g., 20/20, 17/19. (These are in red font.) Compared to the previous
five-year period (see column "2013-2018 Prop, ge CUG"), PCE levels in MW01-08 decreased from
17/20 exceedances to 10/20 exceedances. Well MW01-10 had fewer exceedances for cis-DCE, DCE,
and PCE in the current five-year period compared to the last. Although not shown in Table 2, well
MW03-06 improved during this 5-year period compared to the previous in that fewer exceedances of the
CUG of 1.5ppb (from 9/20 to 2/20) even though there was no real change in the maximum values, from
2.9ppb versus 2.8ppb. In contrast, wells MW03-09 and MW03-11 did not improve compared to the
previous five-year period.

Trend Analysis and Time to Meet Cleanup Goals (CUGs)

An overview of the trend analysis findings is presented in Table 1. Three different trend tests were used.
One, the nonparametric Mann-Kendall (M-K) trend test was performed on all six chemical of concern
for all 14 wells. The results are shown in Table 1. For selected wells and chemicals, the Theil-Sen trend
test was performed in ProUCL and the Seasonal Kendall trend test was performed in VSP. In cases
where the downward trend was statistically significant, estimates of dates when a well would meet the
cleanup goal (CUG) for a particular chemical were estimated using the linear regression equations
estimated by both ProUCL and VSP. Additionally, the Theil-Sen and Sen's slope estimator equations
were also used to estimate the time to meet a CUG. (The former was estimated in ProUCL, the latter in
VSP.) These estimates were also generated for several other chemicals in wells with no significant M-K
trend but which had instances of higher numbers of exceedances of the CUG.

Of the 14 wells examined for the six chemicals of interest, ten wells had levels of each of the six
chemicals of concern at or below their respective CUGs (see Table 1). These wells were: MW01-01,
MW01-02, MW01-03, MW01-07, MW03-04, MW03-05, MW03-06, MW03-12, MW07-13, and
MW07-14. Given that these wells had chemical levels at or below the CUGs, trend analysis was not
performed for most of the chemicals. The only concern in each of these wells is that the reporting limit
(i.e., detection limit) for vinyl chloride (VC) is at the cleanup goal of 0.5ppb. Hence, it will not be
possible to demonstrate that the VC levels in these wells were below the CUG; only that they were at the
CUG.

In the remaining four wells, the levels of one or more chemicals of interest were above their respective
CUGs (see Table 1). These wells were: MW01-08, MW01-10, MW03-09, and MW03-11. These wells
were addressed, in turn.

-------
MW01-08

In well MW01-08 there were four chemicals with values above their respective CUGs (see Table 1).
Three of which had concentrations well above their respective CUGs, i.e., cis-DCE, DCE, and VC. cis-
DCE had a weak to non-existent downward trend, no seasonality, with the possibly of meeting the CUG
in 2062/2067. A relative sense of the significance of these elevated values can been seen in the ratio of
the median to the CUG. That value was 7.0; essentially the median cis-DCE levels were nearly an order
of magnitude higher than the CUG. DCE had a very strong downward trend, no seasonality, with the
possibility of meeting the CUG in 2033. However, the DCE concentrations began to plateau at the end
of 2020, roughly at 40ppb (see Figure 34). The ratio of the median to the CUG was 32 indicating that
the median DCE level is 32 times higher than the CUG (see Table 1). PCE had a downward trend, no
seasonality, and, since, June 2022, the levels were below the CUG. The ratio of the median to the CUG
was 1.33 (see Table 1). Although VC had a median to CUG ratio of 172, two orders of magnitude
higher than the CUG, it had a very strong downward trend, no seasonality, with the possibility of
meeting the CUG at the end of 2023 or in 2024. However, VC concentrations may be plateauing near
50ppb (see Figure 35).

MW01-10

Well MW01-10 had one chemical, DCE, that appeared to have an increasing trend. The Mann-Kendall
trend test found a very weak upward trend and both linear regression and Sen's nonparametric slope
estimate also had upward trends. The ratio of the median to the CUG was 1.2, not an extremely high
ratio. PCE appears to have met the CUG in 2019 and currently had no trend either using the Mann-
Kendall test or the Theil-Sen test. VC had a strong downward trend and all values were at or below the
CUG.

MW03-09

Well MW03-09 had four chemicals that were consistently or often higher than their respective CUGs
(see Table 1). cis-DCE was found to not have a statistically significant trend or seasonality, but the
linear regression and Sen's nonparametric slope estimate generated upward trends. These potential
upward trends may lead this well to go above the CUG in 2029/2030. DCE had no trend, no seasonality,
but the linear regression estimated a downward trend with the possibility of meeting the CUG in 2064,
whereas Sen's nonparametric slope estimate predicted an upward trend. The ratio of the median to the
CUG was 4.27. As with DCE, PCE also had no trend or seasonality, and the linear regression estimated
a downward trend with the possibility of meeting the CUG in 2044, whereas Sen's nonparametric slope
estimate predicted an upward trend.

MW03-11

In well MW03-11 there was only one chemical, PCE, with concentration values of concern (see Table
1). Its median to CUG ratio was 7.33. However, there was a very strong downward trend (see Figure
36), no seasonality, and may possibility meet the CUG by 2029 or 2030. However, concentrations may
be plateauing around 9ppb over the past two years (see Figure 36).

Mann-Kendall graphs and trend results as shown in Figures, 34, 35, and 36 are available for the
remaining chemicals and wells upon request.

1. INTRODUCTION

This Monitored Natural Attenuation (MNA) Efficacy Evaluation for the Vandale
Junkyard Site (Site) was prepared by Geosyntec Consultants, Inc. (Geosyntec) on behalf
of Engineering Management, Inc. (EMI) and the Vandale Junkyard Site PRP Group (The
Group) in accordance with Section 3.8.2 of the Inspection, Maintenance, and Monitoring,
Plan (IMMP). The IMMP indicates that for each five-year review period, a MNA Efficacy
Evaluation will be prepared to assess the effectiveness of MNA processes occurring at
the Site. This Report evaluates the effectiveness of MNA processes at the Site through
September 2021.

1.1	MNA Efficacy Evaluation Requirements

Section 3.8.2 of the IMMP outlines the items to be included in this MNA Efficacy
Evaluation, including:

•	Assessment of progress toward attainment of the Record of Decision (ROD)
performance goals;

•	Summary of data collected during the monitoring period, with a comparison to
ROD cleanup levels; and

•	If the assessment concludes insufficient progress, a discussion of the reasons and
possible corrective measures.

1.2	Objectives

To address the provisions of the IMMP for evaluation of the selected MNA remedy at the
Site, historical groundwater monitoring data have been reviewed and analyzed. The
following analyses have been completed:

•	The current concentrations of constituents of concern (COCs) defined by the ROD
have been compared to the ROD cleanup levels (Table 1) and U.S. EPA
Maximum Contaminant Levels (MCLs) to evaluate the progress of groundwater
restoration via MNA processes;

•	Key MNA indicator parameters that have been measured at the Site have been
evaluated to assess if MNA processes are ongoing;

consultants

•	Statistical trends of groundwater data for select volatile organic compounds
(VOCs) identified in the ROD have been calculated for multiple timeframes to
evaluate MNA progress in decreasing VOC concentrations; and

•	Source decay rates and time to achieve the ROD cleanup goals have been
estimated for VOCs that exceed the ROD cleanup goal and that are characterized
by a decreasing trend.

1.3 Report Organization

The remainder of this MNA Efficacy Evaluation is organized as follows:

•	Section 2 details the Site background including geology, hydrogeology, Site
history and recent MNA evaluations;

•	Section 3 provides a summary of the groundwater monitoring data collected and
analyses completed to evaluate MNA progress;

•	Section 4 details the evaluation of MNA progress and efficacy at the Site; and

•	Section 5 provides a summary of key findings and recommendations.

2. SITE BACKGROUND

The Site is located in Washington County, Ohio, approximately 1.5 miles northeast of
Marietta, Ohio, in Marietta Township Section 18 (Figure 1). Located in the Appalachian
Plateau Province in southeastern Ohio, the Site occupies a 31-acre tract of land,
approximately 10 acres of which are reported to have been utilized as a junkyard. The
Site is located in a rural area on top of a natural ridge. The Site is bordered on two sides
(north and east) by a steep, wooded ravine that approaches 200 feet (ft) deep in places.
An unnamed tributary (designated Tributary A in the Feasibility Study (FS; Metcalf and
Eddy, 1992)), which receives runoff from the Site, is an intermittent tributary in this
ravine and empties into Duck Creek approximately 1,500 ft west of the Site. The Marietta
Sanitation Corporation Landfill, which forms the southern boundary of the Site, was
closed in 1985. The wooded, sloped areas of the Site formerly contained discarded
junkyard materials, debris, and the remnants of drums from industrial waste previously
accepted for disposal at the Site.

2.1 Geology

The sandstone and siltstone strata beneath the Site are typically gray or brown and are
relatively resistant to weathering, occasionally forming ledges on the valley walls that are
identifiable across the Site. The mudstone strata beneath the Site are typically reddish-
brown with some gray intervals. The mudstone is readily weathered and does not form
ledges. Previous investigations confirmed that interbedding of the rock types is common
in the subsurface. Based on geologic logs in the FS Report (Metcalf and Eddy, 1992),
thin layers of resistant siltstone and sandstone were identified from rock cores within
intervals defined as mudstone on the cross section and in the stratigraphic section.
Likewise, layers of less-resistant mudstone occur within intervals identified as the ledge-
forming sandstone. One stratigraphic marker that extends across Washington County is
the Washington Coal. This coal has been identified in the higher elevations of the Site,
ranging in thickness from 2 to 3 feet. A veneer of soil material derived from the
underlying bedrock overlies the bedrock across the Site. Portions of the Site are covered
by colluvium ranging in grain size from clay to boulders deposited by downslope
movement. Some of the soil near the top of the Site may be residual, rather than colluvial,
in nature. The creek (Tributary A) at the foot of the northeast slope is very narrow with
steep side walls of exposed soil and bedrock.

One important deviation of the Site geologic setting is the local-scale slump of bedrock
outcrops along the northern flank of the hillside, where strata were measured at a dip of
3 to 5 degrees north-northeast consistent with the slope direction (opposite, and at a
greater angle of relief than the regional dip direction). The primary relevance of this

consultants

slump feature is its influence on groundwater flow. The incline on the bedrock ledge
promotes the groundwater to flow along the dip of the slump feature, i.e., down the face
of the valley wall toward Tributary A. A conceptual cross-section is shown in Figure 2.

2.2	Hydrogeology

The primary conduit for shallow groundwater flow at the Site is a system of shallow
interconnected fractures. The hydraulic head in these fractures results in a potentiometric
surface that is a subdued replica of the ground surface. The flow characteristics are due,
in part, to the large permeability contrast with the underlying competent rock, where
lower permeabilities slow the vertical migration of infiltrating water creating a water table
in the upper more highly fractured zone. Groundwater flows from higher elevations along
hilltops and discharges in the lower elevations along the valley floor. Groundwater in
this fractured mantle systems is primarily derived from vertical infiltration.

The direction of groundwater flow within the fractured mantle mimics the ground surface
topography. The potentiometric surface map (Figure 3) depicts groundwater flowing in
a northward direction from the ridge along a relatively even hydraulic gradient toward
Tributary A, the discharge location.

2.3	Site History

The Vandale Junkyard Site was a permitted junkyard operation (by Washington County)
from the early 1960s. During its operation, the junkyard accepted a variety of materials
for disposal and/or salvage. These materials included typical household and commercial
wastes such as scrap metal, white goods (refrigerators, stoves, washing machines, etc.),
tires, batteries, automobiles, and non-putrescible municipal waste, as well as a number of
55-gallon drums that contained variable quantities of waste industrial
solvents/degreasers, waste tar and iron cakes, sludges from organic chemical
manufacturing, paint thinners, paints, and ink wastes.

The Site was placed on the National Priority List (NPL) in 1986 and became part of the
Superfund program. The ROD was issued in 1994. Remedial action was completed at the
Site in the late 1990s when soils containing COCs were excavated from the former source
zone, consolidated on-Site with impacted solid waste residue/soil, and covered with a
Resource Conservation and Recovery Act (RCRA) Subtitle C cap. The ROD identified
MNA as the groundwater remedy.

2.4 Recent MNA Evaluations

The progress and efficacy of the selected MNA groundwater remedy has been evaluated
numerous times since monitoring began in 2001 following remedial action. The most
recent MNA Efficacy Evaluation was completed by Antea in 2017 (Antea, 2017)
followed by an MNA Progress Evaluation by Porewater Solutions in 2018 (Porewater
Solutions, 2018) and a Groundwater Contingency Evaluation completed by Geosyntec in
2018 (Geosyntec, 2018). The results of these evaluations supported the use of MNA as
the groundwater remedy for the Site. Specifically, the MNA Progress Evaluation
(Porewater Solutions, 2018) concluded: "Back-diffusion from the fractured rock matrix
is known to require a long remediation timeframe, and is consistent with the ITRC (2017)
guidance manual for remediating fractured rock sites. There is no risk to downgradient
receptors, and the plume is continuing to recede inward over time. There is no technology
currently available which can expeditiously remediate the dissolved constituent mass
stored in the rock matrix. Thus, there is no benefit associated with additional remedial
action at this Site, nor is there a need given the lack of risk and demonstrated MNA
progress. The entirety of the data set demonstrates that natural processes are attenuating
VOCs in groundwater at a rate in excess of VOC back-diffusion from the former source
area."

3.	GROUNDWATER MONITORING DATA ANALYSIS

3.1	Groundwater Monitoring

The groundwater monitoring program currently consists of 14 wells, seven of which are
sampled quarterly (MW03-05, MW03-06, MW01-08, MW03-09, MW03-11, MW07-13,
and MW07-14) and seven of which are sampled on an annual basis (MW01-01, MW01-
02, MW01-03, MW03-04, MW01-07, MW01-10, and MW03-12). The locations of the
monitoring wells included in the groundwater monitoring program are provided in Figure

4.	During the annual sampling event conducted during the second quarter, groundwater
samples are collected from all 14 wells and analyzed for the list of COCs shown in Table
2, which includes 1,1,1-trichloroethane (1,1,1-TCA), 1,1-dichloroethene (1,1-DCE), cis-
1,2-dichloroethene (cis-l,2-DCE), tetrachloroethene (PCE), trans-1,2-dichloroethene
(trans-1,2-DCE), vinyl chloride (VC), bis(2-ethylhexyl) phthalate (BEHP), and several
metals. In addition, in 2018, trichloroethene (TCE) was added to the VOC analysis. For
the remaining quarterly events, groundwater samples are analyzed for the chlorinated
VOCs only.

3.2	Groundwater Monitoring Data

3.2.1	VOCs

Analytical results of groundwater monitoring conducted since 2001 are presented in
Appendix A. Table 2 provides a summary of the results from the most recent groundwater
monitoring event conducted at each location compared to the ROD cleanup goals. In the
most recent groundwater sampling event, VOC concentrations in samples from ten of the
fourteen groundwater monitoring wells did not exceed the ROD cleanup goals. This is
consistent with results since June 2018. Samples from MW01-10 and MW03-11 each had
an exceedance of a single VOC. Samples from MW01-08 and MW03-09 exceeded ROD
cleanup goals for three VOCs each.

3.2.2	Metals and BEHP

Analytical results of groundwater monitoring conducted since 2001 are presented in
Appendix A. Table 2 provides a summary of the most recent groundwater collection event
compared to the ROD cleanup goals. Metals and BEHP had limited exceedances of their
respective ROD cleanup levels over the entire 20-year monitoring period (Appendix A).
During the most recent sampling event in May 2021, there was only one detection of a
metal or BEHP that exceeded a ROD clean up level. Barium was detected at 491 |ig/L in
the sample from MW03-06, in exceedance of the ROD cleanup goal (302 (J,g/L). While
the barium concentration at MW03-06 also exceeded the ROD cleanup goal in 2020 (378

consultants

Hg/L), it had previously not exceeded the ROD cleanup goal since 2006. It is important
to note that although the barium concentrations exceed the ROD cleanup goal, they are
below the U.S. EPA MCL for barium of 2,000 (^g/L.

It should also be noted that the detection limits for BEHP and antimony in 2020 and 2021
were higher than the ROD cleanup goals and in the case of antimony also higher than the
U.S. EPA MCL (Appendix A). The concentrations of BEHP and antimony from 2017 -
2019 were all below the ROD cleanup goals or non-detect with the exception of BEHP,
which exceeded the ROD cleanup goal but not the U.S. EPA MCL in MW01-08 in 2018
and in MW03-09 in 2020.

3.3 MNA Parameters

Several parameters were measured in Site groundwater to assess the contribution that
intrinsic biodegradation is making to the overall natural attenuation process for VOCs in
the Site groundwater. Unimpacted well MW01-1 was used for background comparison.
The groundwater monitoring results for the last five years are summarized in Table 3.

3.3.1	Total Organic Carbon

The process of anaerobic VOC biodegradation by reductive dechlorination consumes
TOC in groundwater. Low levels of TOC (less than 10 mg/L) were detected in all of the
monitoring wells sampled during the last five years (2017 - 2021), providing a line of
evidence that this natural attenuation process is ongoing at the Site.

3.3.2	Nitrate and Nitrite

Anaerobic VOC biodegradation can result in the reduction of nitrate to nitrite and then
nitrogen gas. Background monitoring well MW01-01 has contained measurable levels of
nitrate (0.8 - 1.25 mg/L) from May 2017 - May 2021. However, the monitoring wells in
and downgradient of the former source zone are characterized with low, often non-detect
concentrations of nitrate, indicative of depletion by biodegradation processes. Nitrite
concentrations are also low in Site groundwater, which serves as evidence of degradation
to nitrogen gas.

3.3.3	Iron and Manganese

Iron and manganese reduction are common types of microbial metabolism in
groundwater, suggesting a zone of biodegradation that can concurrently reduce
chlorinated VOCs. Where microbial-induced reduction is occurring, the reduced forms
of iron and manganese (soluble in water and therefore detectable during groundwater
monitoring) accumulate in the zone of biodegradation. Iron was not detected over the past

five years in background monitoring well MW01-01. However, it was detected in
MW01-08 and MW03-09 up to 0.6 mg/L, which are located in the former source zone
where VOC concentrations exceed ROD cleanup goals. Similarly, the downgradient
monitoring wells that still have VOCs above the ROD cleanup goals (MW01-08, MW03-
09, MW01-10, and MW03-11) have elevated concentrations of manganese
(concentrations up to 1.2 mg/L) relative to the background monitoring well (MW01-01)
where concentrations ranged from 0.02 to 0.2 mg/L. This supports the presence of
ongoing anaerobic oxidation of VOCs at the Site under iron-reducing and manganese-
reducing conditions.

3.3.4	Ethane and Ethene

Ethene is the final degradation product of the PCE anaerobic dechlorination pathway,
which includes, in subsequent steps, cis-l,2-DCE, 1,1-DCE, and VC. Ethane is the final
degradation product of the 1,1,1-TCA anaerobic dechlorination pathway. Ethane would
not be expected at the Site, as 1,1,1-TCA concentrations have historically been below the
ROD for at least the last 20 years.

Ethene has been detected in MW01-08, a well in the former source zone with VOC
exceedances of the ROD cleanup goals. The time series graph provided in Figure 5
illustrates how decreasing cis-l,2-DCE concentrations correlate with increasing VC
concentrations starting around 2008. Ethene concentrations appear to track closely with
VC, suggesting that as VC is generated, it undergoes dechlorination to ethene. This
provides evidence that critical microorganisms such as Dehalococcoides ethenogenes,
organisms which facilitate complete dechlorination of PCE to non-toxic endpoints, are
present at the Site.

3.3.5	Alkalinity

Alkalinity is principally a measurement of dissolved carbon dioxide. Biodegradation of
organic compounds produces carbon dioxide; therefore, groundwater undergoing
biodegradation of dissolved organic carbon or VOCs may have elevated alkalinity.
Alkalinity concentrations from June 2017 to May 2021 averaged approximately 280 mg/L
in MW01-01, which serves as the background well. The average alkalinity concentration
in MW01-08 was over 500 mg/L for the five-year period of 2017 through 2021 and the
average concentrations in MW03-09 and MW01-10 for the same time period were
approximately 350 mg/L. The higher than background concentrations of alkalinity
observed in former source zone monitoring wells where VOCs exceed the ROD cleanup
goals suggest MNA processes are ongoing.

3.4 VOC Trends in Groundwater

To evaluate the trends in VOC concentrations over time, Mann-Kendall statistical trend
tests were completed using Site groundwater data collected from three different time
intervals i) the most recent five years; ii) the most recent ten years; and iii) the full
monitoring period with U.S. EPA ProUCL software. The timeframes and associated
rationale are detailed below:

•	September 2017 - September 2021: In recent groundwater evaluations
completed for the Site, U.S. EPA has requested short-term trend evaluations.
Therefore, statistical trends of VOCs with concentrations that have exceeded the
ROD cleanup goal in the most recent five years of groundwater data have been
completed.

•	September 2012 - September 2021: The use of a period longer than 5 years for
near-term trend analysis is recommended in U.S. EPA's guidance "Best Practices
for Environmental Site Management: Recommended Contents of a Groundwater
Monitoring Report" (EPA-542-F-16-005, September 2016). The document states:
"For sites with a long history, it is recommended that trend analyses include only
recent data (e.g., the past 8 to 10 years) to support evaluation of remedy progress."
Therefore, statistical trends of VOCs with concentrations that have exceeded the
ROD cleanup goal in a given well in the last 10 years have been completed.

•	Full monitoring period (at most June 2001 - September 2021): The near-term
trends (for data from the last 5 and 10 years) must be considered in conjunction
with longer-term VOC trends to provide a complete understanding of overall
VOC attenuation at the Site. Therefore, statistical trends of VOCs with
concentrations that have exceeded the ROD cleanup goal in a given monitoring
well at any time over the full monitoring period have been completed.

Trends were only generated for VOCs of concern defined by the ROD in monitoring wells
that had an exceedance of a ROD cleanup goal at least once during the evaluated
timeframe (i.e., last five years, late ten years, or the full monitoring period).

The results of the trend analysis are provided in Tables 4 through 6. Statistical results are
provided in Appendix B. Specific observations include:

•	September 2017 - September 2021: All trends evaluated were stable (10 trends)
or decreasing (2 trends).

consultants

•	September 2012 - September 2021: All trends evaluated were stable (5 trends)
or decreasing (12 trends).

•	Full monitoring period (at most June 2001 - September 2021): A single
increasing trend was observed - PCE in MW03-09. All other trends evaluated
were stable (2 trends) or decreasing (22 trends).

The trend analysis demonstrates that the plume is not expanding.

3.5 Remaining Time to Cleanup VOCs

For those VOCs that showed a statistically significant decreasing trend during the
evaluated time period but remained consistently above the ROD cleanup goal, a source
decay rate constant and the approximate time to achieve the ROD cleanup goal were
estimated for each compound using U.S. EPA SourceDK software (see Table 7). If a
VOC concentration fluctuated above and below the ROD cleanup goal during the most
recent five-year monitoring period (2017-2021), this evaluation was not completed for
the specific VOC at that location because it is anticipated that the parameter will
consistently achieve its cleanup level in the near term. As such, three VOCs in two wells
were excluded: 1,1-DCE and PCE in MW01-10 and cis-l,2-DCE in MW03-09.

Source decay rates were calculated for remaining VOCs exceeding cleanup goals in
monitoring wells MW01-08 (1,1-DCE; cis-l,2-DCE, and VC), MW03-09 (1,1-DCE and
PCE) and MW03-11 (PCE) using VOC data from each of the three different time periods
that were used to evaluate the concentration trends. Each of these wells is discussed
further below.

MW01-08: Based on the most recent sampling event, three VOCs remain above the ROD
cleanup goals in MW01-08, located in the former source zone: 1,1-DCE, cis-l,2-DCE,
and VC (Table 2). The concentration trends for the three VOCs were stable or decreasing
over all three time periods of data evaluated:

•	1,1-DCE - A decreasing trend was observed for 1,1-DCE, both with data from
2001 - 2021 and with the most recent 5 years of data (2017 - 2021). Based on
long-term data, the time to achieve cleanup for this VOC is approximately 90
years; however, recent data in the last five years suggests a more rapid cleanup of
approximately 25 years.

•	cis-l,2-DCE - The longest time to cleanup, regardless of the dataset evaluated,
was observed for cis-l,2-DCE, which is approximately 70-100 years.

consultants

• VC - VC was observed to have a stable trend when evaluating data for the five-
year dataset or the full monitoring period. A decreasing trend was observed when
evaluating data over the past ten years (2012 - 2021). For the ten-year dataset, the
time to achieve ROD cleanup goals is approximately 30 years.

MW03-09: Based on the most recent sampling event, two VOCs remain consistently
above the ROD cleanup goals in MW03-09, located in the former source zone: PCE and
1,1-DCE (Table 2). PCE concentrations show stable trends in recent monitoring data
(2017 - 2021 and 2012 - 2021) and increasing trends over the full monitoring period
(2003 - 2021); therefore, the time to achieve cleanup goals was not calculated for PCE.
1,1-DCE was observed to have a stable trend when evaluating data for the last five years
or the full monitoring period and a decreasing trend when evaluating data over the past
ten years (2012 - 2021). For this ten-year dataset, the time to achieve ROD cleanup goals
is approximately 10 years.

MW03-11: PCE is the only VOC above its ROD cleanup goal in monitoring well
MW03-11 (Table 2). MW03-11 is located sidegradient of the former soil excavation area
and PCE in this well is predicted to achieve concentrations below the ROD cleanup goals
in less than approximately 15 years regardless of the timeframe of data evaluated.

This evaluation indicates that MNA is attenuating the plume over time. As expected, the
former source zone will require the greatest amount of time to restore (the ROD notes
that "ground water contamination may be especially persistent in the immediate area of
the contaminant sources"). The majority of monitoring wells contain VOCs below or
fluctuating just above and below the ROD cleanup goals. Based on recent data for the
last 5 to 10 years, the few VOCs at MW01-08, MW03-09, and MW03-11 that are
consistently above ROD cleanup goals but exhibit decreasing trends are expected to
achieve cleanup goals in about 25 years or less, with the exception of cis-l,2-DCE (which
is predicted to take longer to reach cleanup goals at MW01-08).

4. EVALUATION OF MNA EFFICACY

4.1 Monitored Natural Attenuation Evaluation Summary

There are two naturally occurring processes resulting in substantial attenuation of COCs
at the Site:

•	VOC degradation as evidenced by decreasing and stable trends described in
Section 3.4, along with favorable geochemical conditions as demonstrated by
MNA indicator parameters as described in Section 3.3; and

•	Matrix diffusion as discussed in detail in the MNA Progress Evaluation
(Porewater Solutions, 2018) and further supported by this evaluation, which
includes:

o Forward matrix diffusion in the downgradient plume, which is
substantially retarding the COC plume and preventing offsite migration,
thereby reducing risk; and

o Depletion of dissolved mass stored in the rock matrix along with a
corresponding decline in back-diffusion, which is causing the COC plume
to recede over time.

Each of these processes are described in more detail in subsequent sections.

4.1.1 Summary of COC Trends Over Time

At most wells, COC concentrations have been steadily declining over time and are now
below the respective cleanup goals. Based on the most recent sampling event (May or
September 2021), there are only four of 14 monitoring wells that currently have VOC
exceedances of the ROD cleanup goals (MW01-08, MW01-10, MW03-09, and MW03-
11) and one monitoring well with a barium exceedance of the ROD cleanup goal (MW03-
06) (Table 2). It is important to note that the exceedances of VOCs in MW01-10 and
barium in MW03-06 are below U.S. EPA MCLs. Therefore, only three wells, two of
which are in the former source area (MW01-08 and MW03-09), still maintain VOCs at
concentrations exceeding both the ROD cleanup goals and MCLs. The concentration
trends for VOCs in exceedance of the ROD cleanup goals were evaluated over time as
described in Section 3.4.

The trend results suggest the following about the progress of MNA at the Site:

•	Most trends observed, regardless of the time period evaluated, are decreasing or
stable, suggesting on-going MNA progress at the Site.

•	A single increasing trend of PCE was observed in MW03-09, located in the soil
removal area, when the full monitoring period of data was evaluated. The trends
for more recent data (5-year and 10-year datasets) were stable. A visual review of
the PCE groundwater concentrations (Figure 6) in MW03-09 in the last five years
(since 2017) suggest that the concentration is now stable and beginning to decline.

•	The numerous observed decreasing trends, regardless of the time period
evaluated, provide supporting evidence that MNA processes are attenuating
VOCs at the Site.

Downgradient and sidegradient monitoring wells MW01-02, MW01-03, MW03-04,
MW03-05, MW03-12, MW07-13 and MW07-14 have not had VOC exceedances of ROD
cleanup goals in the last 14 years. Downgradient/sidegradient monitoring well MW01-07
has not had VOC exceedances of the ROD cleanup goals in the last nine years.
Downgradient/sidegradient monitoring well MW03-06 has not had VOC exceedances of
the ROD cleanup goals in the last three years. Only one VOC (PCE) present in
downgradient/sidegradient well MW03-11 exceeds its cleanup goal, and it is exhibiting
a decreasing trend regardless of the timeframe data set evaluated.

These temporal trends indicate that dissolved constituent VOC mass stored in the rock
matrix in former source areas is depleting naturally over time and not migrating to
downgradient and sidegradient monitoring wells. In addition, the plume is not expanding
and migrating off-Site, as evidenced by no detections of Site-related VOCs in Tributary
A, the final groundwater discharge point (Table 8). The rate of decline has been observed
to be slower at MW01-08 and MW03-09 than at other wells, presumably due to the effects
of back-diffusion in the former source area (Porewater Solutions, 2018).

4.1.2 Plume Attenuation

COC concentrations attenuate by orders of magnitude downgradient from the former
source area, due to the combined processes of degradation and forward matrix diffusion
occurring in the plume (Geosyntec, 2018 and Porewater Solutions, 2018). The strength
of these attenuation processes has caused the COC plume to recede inwards towards the
former source area, which demonstrates that MNA is progressing sufficiently, and
additional remedial measures are not necessary.

Figures 7 through 10 present a summary of the receding plume conditions for 1,1-DCE,
PCE, cis-l,2-DCE, and vinyl chloride, respectively. The historical extent of exceedances
of each VOC is provided on the figure. The current extent of VOCs is indicated using the
most recent set of data collected from each monitoring well. The VOC concentrations
remain the highest in the former source area characterized by MW03-09 and MW01-08.
In addition, a single VOC exceedance, each, is observed in MW01-10 and MW03-11. In
general, the VOC exceedances have receded as exceedances are no longer observed in
MW03-06 and exceedances observed in MW01-10 and MW03-11 are only slightly above
the ROD cleanup goals, providing evidence of the plume recession.

4.1.3 MNA Progress Summary

Natural attenuation is occurring at varying rates due to the natural physical properties of
the aquifer matrix and the distribution of COCs at the Site. The continued presence of
COCs in groundwater is attributed to a secondary source of dissolved mass in the low-
permeability rock matrix. Back-diffusion of dissolved COC mass, from the rock matrix
into open fractures in the former source area, is causing low COC concentrations to
remain in groundwater in the shrinking plume at the Site.

The attenuation over distance for all COCs, combined with the depletion of back-
diffusion contributions to the plume is resulting in the receding COC plume observed at
the Site. This indicates that risks are continuing to be reduced at the Site, and that MNA
is continuing to progress towards groundwater restoration.

There are currently four wells at the Site where one or more VOCs exceed cleanup goals:
MWO1-08, MW03-09, MWO1-10, and MW03-11. VOC trends at MWO1-10 indicate that
this well is progressing quickly to restoration and will be below the cleanup goals in the
near-term. All VOCs are currently below MCLs at MW01-10. VOCs in MW01-08 and
MW03-11 are exhibiting downward trends and decay rates associated with a receding
plume in the long-term, but will take longer to remediate due to the slow decline in back-
diffusion contributions in the vicinity of these two wells (Geosyntec, 2018). An
evaluation of VOC trends at MW03-09 should be conducted again in five years to
determine if the VOC concentration stability observed over the last five years at this well
will continue or if the concentrations begin to statistically decline.

The entirety of the data set presented in this MNA Efficacy Evaluation demonstrates that
natural processes are degrading COCs faster than the flux from back-diffusion in the
former source area, and thus reducing the overall contaminant mass.

4.2	Alternative Remedy Evaluation

The information presented above indicates that MNA processes are ongoing at the Site
and are actively attenuating VOCs in Site groundwater.

A contingency evaluation prepared in 2018 to evaluate alternative groundwater
remediation technologies (Geosyntec, 2018) concluded that MNA is the best remedial
option for Site remediation. As detailed in the contingency evaluation, back-diffusion
from the fractured rock matrix is known to require a long remediation timeframe and is
consistent with the ITRC (2017) guidance manual for remediating fractured rock sites.
There is no risk to downgradient receptors, and the plume is continuing to recede inward
over time. There is no technology currently available which can more expeditiously
remediate the dissolved constituent mass stored in the rock matrix. Thus, there is no
benefit associated with additional or alternative remedial action at this Site, nor is there a
need given the lack of risk and demonstrated MNA progress.

4.3	Institutional Controls

An Environmental Covenant was recorded in February 2019 on 30.5 acres encompassing
most of the Site. The Environmental Covenant prohibits groundwater use until
groundwater cleanup goals are achieved and requires that any residential use of the parcel
requires U.S. EPA written approval. An Environmental Covenant was recorded on a 0.4-
acre portion of the Site in January 2021. This Environmental Covenant prohibits
groundwater use until groundwater cleanup goals are achieved.

5. SUMMARY AND RECOMMENDATIONS

In summary, the following conclusions can be made based upon this MNA Efficacy
Evaluation:

•	Expeditious progress, defined by U.S. EPA as statistically significant, decreasing
VOC trends through time, is occurring via MNA at most monitoring wells on-
Site. Historical practices at the Site support the occurrence of spatially dispersed,
small areas of residual COC mass in the rock matrix below the water table that
are generally impracticable to identify and remediate but that can sustain low
levels of COCs in groundwater through back diffusion; a level that MNA is
controlling, as evidenced by Site data, a single increasing VOC trend, and an
overall receding plume footprint.

•	VOC concentrations are decreasing, as evidenced by plume shrinkage and
receding source decay rates, at an expected and acceptable rate given the fractured
rock geology of the Site. Remedial actions accomplished to date have effectively
eliminated the majority of source mass, minimized the influx of dissolved VOCs
from existing residual mass locations, and stabilized the Site such that natural
attenuation processes are controlling dissolved concentrations and prohibiting
migration of COCs as the Site progresses toward long term restoration.

•	Data show that the COCs are not migrating off-Site as evidenced by VOCs
measured below the ROD cleanup goals or non-detect in the following
downgradient/sidegradient monitoring wells for at least the last nine years:
MW01-02, MW01-03, MW03-04, MW03-05, MW01-07, MW03-12, MW07-13,
and MW07-14. In addition, surface water sampling locations in the ultimate
groundwater discharge point of Tributary A were non-detect for VOCs in 2021
(Table 8) and have been since monitoring began in 2001.

•	Environmental indicators from the Site provide support that the selected remedy
achieves the goals of Superfund because human exposure is controlled (i.e., there
is no complete exposure pathway for direct contact with potable groundwater;
sufficient groundwater is not even available to support residential or agricultural
pumping), and groundwater containing COCs is not migrating off-Site. Off-Site
migration of groundwater containing COCs has not been observed during the
entire monitoring period beginning in 2001.

Notes:

NS = no standard

BEHP = Bis(2-Ethylhexyl)phthalate
VOC = volatile organic compound
MCL = maximum contaminant level
ROD = record of decision
— indicates no sample collected
< indicates value below the reporting limit

* = The ROD does not provide separate cleanup levels for cis-1,2-dichloroethene and trans-1,2-dichloroethene. One cleanup level of 100 jxg/L was assigned to both.

The data included is the most recent sampling event for each constituent. Annually sampled monitoring wells were sampled for the full suite of COCs in May 2021 and VOCs were

sampled in September 2021 for monitoring wells sampled quarterly.

All VOC and Semi-VOC results are in micrograms per liter (jxg/L)

All Metals results are in milligrams per liter (mg/L)

Bold highlighed numbers indicate results that have exceeded ROD cleanup levels

Notes:

NS = no Record of Decision (ROD) cleanup standard
-- indicates no sample collected
< indicates value below the reporting limit

* = The ROD does not provide separate cleanup levels for cis-l,2-dichloroethene and trans-l,2-dichloroethene.

One cleanup level of 100 |ig/L was assigned to both.

All VOC, Semi-VOC, and Gas results are in micrograms per liter (|ig/L)

All Metals results are in milligrams per liter (mg/L)

Bold highlighted numbers indicate results that have exceeded ROD cleanup levels
