16. Abstract (Umlt: 200 words)                       
 The 4.S-acre Picillo Farm site is a former pig farm located in Coventry, Rhode Island,
 approximately 20 miles southwest of Providence,  Rhode Island. The site lies one mile
 west of the Quidnick Reservoir, which is used for recreational purposes. The two 
 closest residences are located on the farm, and an estimated 40 houses are within a
 one-mile radius of the site. Al~ residences are served by private wells. Land use in
 the area is predominantly residential,  with adjacent woodland and wetland areas. In
 1"977, drums containing hazardous waste and bulk waste were disposed illegally into six
 different trenches (Northeast, Northwest, West,  South, and two slit trenches) within a
 7.S-acre area of the farm. Waste disposed of at the site included industrial solvents,
 oils, pesticides, PCBs, paint sludge, resins, still bottoms, and other hazardous 
materials; the total volume of which is unknown. As a result of a sodium aluminum 
 hydride explosion and fire at the site in 1977,  the dumping activities were brought to
 the attention of regulatory agencies. Since then, a number of remedial activities have
 been conducted at the site. Between 1980 and 1982, the State and EPA engaged in a 
 joint cleanup by excavating and disposing offsite approximately 10,000 drums and 
 contaminated soil from the six trenches, and stockpiling onsite other soil contaminated

Abstract (Continued)
with PCBs and phenols. A 1985 ROD provided for the disposal of contaminated soil in an
onsite RCRA landfill, but a 1987 ROD amendment designated the stockpiled contaminated soil
to be disposed of offsite. In 1988, EPA ordered four of the PRPs to remove the
contaminated soil and perform site closure activities. This ROD addresses a final remedy
for the soil and ground water. The primary contaminants of concern affecting the soil and
ground water are VOCs, including benzene, PCE, TCE, and toluene; other organics, including
PCBs and pesticides; and metals, including chromium and lead.
The selected remedial action for this site includes treating 130 yd3 of contaminated soil
using an onsite in-situ soil vapor/vacuum extraction system to extract soil vapors
contaminated with VOCs and SVOCs; dewatering the soil in conjunction with the vapor/vacuum
extraction; pumping the contaminated vapors through a vapor liquid separator; sending the
liquid component offsite for treatment and disposal; passing the air component through a
thermal oxidation system; treating the residual hydrochloric acid generated by the thermal
oxidation using a caustic scrubber; disposing of the residual brine solution offsite;
excavating approximately 600 yd3 of PCB-contaminated soil, and disposing of them offsite
at a TSCA-regulated treatment, storage, and disposal facility; combining extracted ground
water with water from the dewatering operations; pretreating the water with equalization
and precipitation to remove contaminants/solids and metals, respectively, with offsite
disposal; pumping the contaminated ground water to a UV/oxidation system, followed by
activated carbon filters; reinjecting the treated ground water onsite or discharging this
onsite to surface water; regenerating and reusing spent carbon periodically; allowing for
natural attenuation in the dilute portion of the plume; conducting environmental
monitoring, including sampling of monitoring wells, residential wells, surface water, and
sediment to evaluate the performance of the treatment system, the rate of natural
attenuation, and the overall effectiveness of the remedy; and implementing institutional
controls, including ground water and surface water use restrictions, and site access
restrictions. The selected remedial action for ground water is contingent upon whether
air stripping becomes more cost-effective than UV/oxidation. The estimated present worth
cost for this remedial action is $15,700,000, which includes an estimated present worth
O&M cost of $11,400,000. The estimated present worth cost for the contingency remedy is
$18,900,000, which includes an estimated present worth O&M cost of $18,000,000.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil cleanup goals are based on Summers Leaching Model, SDWA MCLs,
MCLGs, and an Ecological Risk Assessment (ERA), and include benzene 5 ug/kg; TCE 5.1
ug/kg; toluene 990 ug/kg; and PCBs 1,300 ug/kg. Chemical-specific interim ground water
cleanup goals are based on SDWA MCLs, SDWA MCLGs, and Action Levels and include benzene 5

DESCRIPTION OF THE SELECTED REMEDY
This ROO sets forth the selected remedy for the picillo Farm
Site, which includes both source control and management of
migration components to obtain a comprehensive remedy.
The major components of the selected source control remedy
include:
.
In situ enhanced vacuuci extraction of contaminated soil to
remove volatile organic compounds (VOCs) and semivolatile
organic compounds tSVOCs). Activated carbon air emission
control technology will prevent the transfer of VOCs and
?VOCs from the soil to the atmosphere. Soil cleanup levels
are predicted to be achieved within an estimated 3 years of
operation. A pilot test will be conducted as part of the
design to optimize the system prior to the full scale
operation;
.
Excavation and off-site disposal of surface soil
contaminated with polychlorinated biphenyls (PCBs);
.
Access restrictions to the source area, such as fence
construction; and
.
A soil monitoring program to demonstrate compliance with
soil cleanup levels and a performance monitoring program to
evaluate the effectiveness of the enhanced vapor extraction
system and the need to adjust or modify operating parameters
of the system. .
The major components of the selected management of migration
remedy include:
.
Extraction of contaminated ground water from the overburden
and shallow bedrock aquifers using extraction wells;

Treatment of contaminated ground water using ultraviolet
(UV)/oxidation with activated carbon adsorption. The
treated water would be reinjected into the aquifer or
discharged to the surface waters. Contingent upon cost
estimates during design, EPA may implement air stripping
with activated carbon air emission controls in place of
UV/oxidation treatment technology;
.
.
An environmental monitoring program to evaluate the extent
of contamination over time; to demonstrate compliance with
ground water and surface water cleanup levels and the need
to adjust or modify operating parameters of the system. The
monitoring program shall operate until the ground water and
surface water are restored to the drinking water standards
and are protective of human health and the environment,

-------
which is predic~ed to ~ccur ;;i~hin approximately 20 years.
.
Institutional controls to pre~ent the use of contaminated
groundwater and surface wate~ as a drinking water source
until the cleanup levels are ~et.
DECLARATION
The selected remedy is protective of the human health and the
environment, attains federal and state requirements that are
applicable or relevant and appropriate for this remedial action,
and is cost-effective. This remedy satisfies the statutory
preference for remedies that utilize treatment as a principal
element to reduce the toxicity, mobility, or volume of hazardous
substances. In addition, this remedy utilizes permanent
solutions and alternative treatment technologies to the maximum
exten~ practicable.

RECORD OF DECISION SUMMARY
PICILLO FARM SITE
SEPTEMBER 27, 1993
I.
SITE NAME, LOCATION AND DESCRIPTION
The Picillo Farm Site is located on Piggy Hill Lane in Coventry,
Rhode Island, southwest of the intersection of State Highway 102
and Perry Hill Road (Appendix A, Figure 1). Coventry is a town
of approximately 31,000 residents and is located approximately 20
miles southwest of Providence. The Site was listed on the
National Priority List (NPL) in September 1983. The Site
includes the 7.5-acre disposal area where illegal disposal
activities had been documented, which is currently fenced, and,
based on the extent of contamination, approximately 35 acres of
surrounding woodland and wetland areas.
The Site is located in a rural area and is surrounded by mixed
woods and wetlands. Approximately 40 houses are located within a
one mile radius north, northeast and east of the disposal area,
along Perry Hill Road, West Log Bridge Road, and Victory Highway,
with the closest two residences located on the picillo Farm
property, approximately 1,300 feet north from the disposal area
boundary. A new development is being built along West Log Bridge
Road northeast of the Site, with new houses as close as 2,000
feet from the disposal area. All these residences are served by
private wells.
The disposal area is situated just west of the surface-water
divide, which separates the Pawtuxet River watershed to the east
from the Quinebaug River watershed to the west. The disposal
area is an upland field located on the northwest slope of a
broad, flat, northwest-sloping ridge. The picillo Farm lies one
mile west of the Quidnick Reservoir, which is used for.
recreational purposes. An Unnamed Swamp, bordering the site to
the west, drains into Whitford Pond and Great Cedar Swamp,
located approximately one mile southwest of the farm. The
wetlands and surface waters adjacent .to the Site are considered
Class A waters according to the Rhode Island Water Quality
Regulations for Water Pollution Control.
The Site is underlain by unconsolidated overburden materials
which include glacial outwash deposits ranging from 20 to 80 feet
in thickness. The deposits consist primarily of fine to coarse
sand and gravel with scattered boulders in upland areas and
organic-rich swamp deposits in some lowland areas. Lenses of
silty sand and clay have been observed at some locations but are
not common.
Compact boulder-rich till consisting of a poorly sorted mixture
of sand, gravel, silt and boulders underlies much of the picillo
study area. The till unit varies in thickness from 5 to 40 feet
and is laterally discontinuous. A thick unit of boulders present

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 2
rather than boulder-rich till was observed in portions .of the
disposal area, ranging from less than a few feet thick to more
than 20 feet thick.
The glacial deposits are underlained by a generally highly
fractured and weathered bedrock. From bedrock core observations
it appears that ground water flows through fractures as well as
through the weathered rock matrix. The remedial investigation
(RI) determined that approximately 10 to 40 feet of weathered
bedrock overlies competent bedrock in most locations. The degree
of weathering and fracturing in bedrock varies considerably
throughout the Site. Boring logs from two deep bedrock wells to
the northwest and southwest of the disposal area show heavily
weathered bedrock to ten feet below the bedrock surface and
fractured and weathered zones to depths of over 100 feet. For
the most part, the RI defined shallow bedrock as the uppermost 20
feet of bedrock.
Several significant features of the bedrock surface beneath the
Site (Appendix A Figure 2) are: (1) a bedrock trough which
extends from the northeast portion of the disposal area in a
northeast direction and forms a bedrock low under a small pond on
the Picillo Farm property in the vicinity of monitoring wells MW-
35 and MW~59; (2) fractures extending in a north-northwest
direction from the pond up to Perry Hill Road; (3) a local
bedrock topographic high under the disposal area from which the
bedrock slopes toward the west, north and east; and (4) a
northeast-southwest treading fracture system underneath the
Unnamed Swamp drainage. The highest bedrock elevations occur in
the western portion of the disposal area and to the south of the
disposal area. Bedrock lows coincide for the most part with
surface water bodies in the area. Outcroppings of bedrock are
also found throughout the area.
The unconsolidated sands and gravels are highly permeable with
moderate to high hydraulic conductivities. Sand and silt
mixtures are less permeable and have lower conductivities. Most
of the till encountered at the Site contains predominantly sand,
gravel and boulders, instead of fine silts and clays, and is
moderately permeable. By contrast, the clay lenses and silt
lenses appear to act as semi-permeable layers in highly localized
areas. Weathered shallow bedrock, especially to the west,
northwest and southwest of the disposal area has a moderate to
high permeability. Less weathered shallow bedrock to the east
and south of the disposal area, is much less permeable. Ground
water flow in the competent bedrock takes place primarily in
interconnected networks of fractures.
The predominant direction of overland runoff and ground water

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 3
is from the disposal area toward west and southwest. Most of the
ground water discharges into the Unnamed Swamp and Great Cedar
Swamp; surface water flow in these water bodies is south and
southwest. Ground water flow in the deep, more competent bedrock
is controlled by the fractures and the bedrock matrix. Deep
bedrock, shallow bedrock and overburden are found to be
hydraulically connected, thus the ground water can readily move
between the unconsolidated sediments and the bedrock.
A more complete description of the Site can be found in the
Picillo Farm Remedial Investigation Report, December 1992 (RI
Report), in sections 1 and 3.
II.
SITE HISTORY AND ENFORCEMENT ACTIVITIES
A.
Land Use and Response History
The characterization of current land use was performed
through the interpretation of aerial photographs, zoning
maps and site visits. The Site is located in a central
rural section of Rhode Island, is removed from metropolitan
areas and is currently zoned for rural/residential use. In
1988, because of the concerns about site contamination, the
Town of Coventry placed a moratorium on building near the
site. A year later, a local developer successfully
challenged the moratorium in court resulting in residential
development in the vicinity of the site. As a potential
future land use, EPA considered residential development of
upland portions of the Site and continued recreational use
of the wetlands on the Site.
The Picillo Farm property had been used as a pig farm when
drums containing hazardous wastes and bulk wastes were
illegally disposed into several trenches within a 7.5-acre
area of the farm over a period of months in 1977. Wastes
disposed of at the Site included industrial solvents, oils,
pesticides, PCBs, paint sludges, resins, still bottoms, and
other hazardous materials. The total volume of the
materials disposed at the Site is unknown. In September
1977 a sodium aluminum hydride explosion and fire at the
site brought the dumping activities to the attention of
regulatory agencies.
Since September 1977, a number of investigations and
remedial activities have been conducted at the site. The
State of Rhode Island and EPA engaged in joint cleanup
activities/supervision and single-party cleanup
activities/supervision. Between 1980 and 1982 the trenches
located along the perimeter of a cleared field -- the

-------
RECORD OF DECISION SUMMARY
Picillo Farm Site
Page 4
trench, and two slit trenches -- were excavated,
approximately 10,000 drums and contaminated soil were
removed and disposed off site. Some of the contaminated
soil from this excavation was placed in three stockpiles on
the site and was designated as the PCB pile and the first
and second phenol piles (Appendix A, Figure 3). In 1982, a
RIDEM contractor performed land farming of the first phenol
waste pile and decreased the phenol concentration from
approximately 870 ppm to 60 ppm. pilot studies conducted by
RIDEM on the biodegradation of the soils contaminated with
polychlorinated biphenyls (PCBs) proved to be unsuccessful.
In 1985, after conducting a Remedial Investigation/
Feasibility Study (RI/FS), EPA issued a Record of Decision
(ROD) which called for disposal of contaminated soil in an
on-site RCRA landfill. The State of Rhode Island contested
the ROD, and in 1987, following the enactment of the
Superfund Amendments and Reauthorization Act (SARA), EPA
issued an amended ROD. The amended ROD called for the off-
site disposal of stockpiled contaminated soil and the
implementation of the Remedial Investigation/Feasibility
Study (RI/FS) to determine the nature and extent of the
residual contamination and to evaluate cleanup alternatives.
In 1988, under an agreement with EPA, four of the
Potentially Responsible Parties (PRPs) performed the off-
site removal of the contaminated soil and site closure
activities: filling, grading and revegetating the Site,
constructing of a surface water runoff control system, and
installing a fence.
A more detailed description of the Site history can be found
in the RI Report, Sections 1 and 3.
B.
Enforcement History
EPA initially proposed the Site for the NPL on October 23,
1981. On December 15, 1981, EPA notified approximately ten
(10) parties who either owned or operated the facility,
generated wastes that were shipped to the facility, arranged
for the disposal of wastes at the facility, or transported
wastes to the facility of their potential liability with
respect to the Site and requested them to undertake the
clean-up of the Site. On January 20, 1983, EPA notified
approximately twenty (20) parties of their potential
liability. FOllow-up notice letters were sent to
approximately eleven (11) parties on April 12, 1983, and
approximately nineteen (19) parties on April 17, 1985
inviting them to participate in settlement negotiations.
Negotiations commenced with these potentially responsible

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 5
the PRP's liability at the Site and continued in 1985 and
1987. On October 27, 1987, EPA notified approximately
seventeen (17) additional parties of their potential
liability with respect to the Site and the on-going
negotiations with a group of PRPs.
These substantial negotiations resulted in four (4)
settlements agreements with twelve parties for a total
recovery of $1.6 million in EPA's past costs, plus an
agreement by four of the parties to perform a source ~ontrol
remedial action specified in the 1987 Record of Decision.
Rhode Island also recovered some of its past costs under
these settlements. .
In October 1989, EPA filed a lawsuit against two non-
settlers to recover the remainder of its past costs.
Pursuant to the March 1992 court judgment, EPA received a
total of nearly $4 million toward cleanup of the Site. The
court found the parties liable with respect to the site and
upheld EPA's authority to pursue responsible parties for the
cost of cleanup actions performed by the government.
On March 8, 1993, EPA notified approximately 17 parties of
their liability or potential liability and requested their
voluntary participation in the remaining cleanup activities.
The PRPs have been active in the remedy selection process
for the ground water contamination at the site. In 1992 and
1993 EPA met several times with the PRPs' technical
committee to discuss the findings of the RIfFS. Technical
comments presented by PRPs during the public comment period
are included in the Administrative Record. A summary of
these comments as well as EPA's responses, which describe
how these comments affected the remedy selection, are
included in the Responsiveness Summary (Appendix D) of this
document.
The State of Rhode Island also took enforcement actions at
the Site. In October 1977, following the discovery of the
illegal dumping, the State filed suit against the site
owners. The court ordered the site owners to remove all
contaminated materials and dispose of them at a facility
approved by the state and to perform a study of the ground
water contamination. The site owners failed to comply and
were found in civil contempt. In 1983 the State filed suit
against thirty-five (35) parties (owners, generators and
transporters), settled with twenty (20) of these parties,
obtained default judgment against the Site owners and
dismissed one (1) party. In May 1987, the court found three

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 6
to pay approximately $1.5 of the State's past costs.
The State filed several other lawsuits against the Site
owners. In 1979 the State challenged the conveyance of the
Site by the owners of the Site at that time. The conveyance
was voided and the Town of Coventry eventually acquired the
Site through a tax delinquency sale. The State also filed
an action to seize property in Florida owned by the former
Site owners.
III. COMMUNITY PARTICIPATION
Throughout the Site's early history, community concern and
involvement has been moderate to high. Before 1981, most
community relations activities were conducted by the State. In
1980, local citizens formed a group called Save our Water (SOW)
which represented concerned citizens and became the primary point
of contact between the community and involved agencies.
Recently, the group has been less active.
During the removal and remedial actions and investigations, EPA
has kept the community and other interested parties apprised of
the Site activities through informational meetings, fact sheets,
press releases and public meetings. EPA also maintained an
information repository near the Site.
During October 1981 EPA issued the first community relations plan
for the Site. In 1984 and 1990, EPA released revised community
relations plans which outlined a program to address community
concerns and keep citizens informed about and involved in
activities during remedial activities. EPA's informational
meeting for the first ROD was held on April 22, 1985, followed by
a public hearing on May 15, 1985. A public meeting was also held
on May 7, 1987, following the issuance of the amended record of
decision.
On September 7, 1990 EPA made the administrative record available
for public review at EPA's offices in Boston and at the Coventry
Public Library, 1672 Flat River Road, Coventry, Rhode Island.
The administrative record was updated on January 31, 1991 and
June 22, 1993. EPA published a notice and brief analysis of the
Proposed Plan in the Kent County Daily Times on June 22, 1993,
and in the Providence Journal Bulletin on June 25, 1993, and made
the plan available to the public at the Coventry Public Library.

On June 29, 1993, EPA held an informational meeting to discuss
the results of the Remedial Investigation and the cleanup
alternatives presented in the Feasibility Study and to present
the Agency's Proposed Plan. Also during this meeting, the Agency

accept public comments on the alternatives presented in the
Feasibility Study and the Proposed Plan and on any other
documents previously released to the public. On July 13, 1993,
the Agency held a public meeting to discuss the Proposed Plan and
to accept any oral comments. A transcript of this meeting and
the comments and the Agency's response to comments are included

IV.
SCOPE AND ROLE OF OPERABLE UNIT OR RESPONSE ACTION
The remedy described in this Record of Decision addresses the
remaining contamination at the Site. Removal of the drums and
contaminated soil conducted in the early 1980s reduced the
immediate threat to public health from exposure to hazardous
waste contained in the drums and trenches. The first Record of
Decision, signed in September of 1985, as amended in March of
1987, required removal of the remaining stockpiled soil and site
closure activities. That remedy reduced the risk to public
health from exposure to contaminated soil remaining onsite.
The selected remedy in this Record of Decision was developed by
combining a source control and a management of migration
alternative to cleanup the remaining contamination. In summary,
the remedy provides treatment of contaminated ground water and of
residual soil contamination. This remedial action will address
the remaining principal threats to human health and the
environment posed by the residual soil contamination, that
presents a continuing source for leaching of contaminants into
the ground water at the Site.
V.
SUMMARY OF SITE CHARACTERISTICS
Chapter 2 of the Feasibility Study contains an overview of the
"Remedial Investigation. The significant findings of the Remedial
Investigation are summarized below. ~"
A.
Ground water
Geological investigations, including fracture trace
analysis, seismic refraction and very low frequency (VLF)
surveys, soil boring and bedrock coring programs were used
to determine how the area geology influences ground water
flow and contaminant transport. Depth to ground water
beneath the Site is fairly shallow, ranging from zero (at
seep and wetland locations) to 30 feet (southeast of
disposal area) below ground surface. The saturated
thickness of the overburden varies between zero and 50 feet.
The water level in the area fluctuates significantly in

-------
RECORD OF DECISION SUMMARY
Picillo Farm Site
Page 8
fluctuation observed in some monitoring wells.
Based on the monthly water level measurements in the
monitoring wells, ground water flow patterns in the
overburden and shallow bedrock are determined to generally
follow surface drainage patterns. The RI has determined
three ground water flow paths in the overburden and shallow
bedrock, all originating in the disposal area and flowing in
the general northwest, west and southwest directions and
discharging into the Unnamed Swamp and Great Cedar Swamp.
Data from historical pump tests and pump tests performed
during this RI, demonstrated that overburden, shallow
bedrock and deep bedrock are hydraulically connected. In
the deeper, more competent bedrock, fractures are likely to
be the major flow paths.
Thirty two (32) wells were installed in overburden and
shallow bedrock during this RI, bringing the total number of
monitoring wells to seventy five (75). Ground water samples
were taken quarterly at each of the monitoring wells and
analyzed for over 100 different contaminants. The RI found
that the contaminated ground water flowing from the former
disposal area consists of a wide variety of halogenated,
aromatic, and water soluble solvents, phenols, phthalates,
and their respective degradation products (Appendix A,
Figures 4 through 7). Sampling to date has indicated that
the volatile contaminants concentrations, while exhibiting
some variation and seasonal fluctuation, have not decreased
significantly since the mid-1980s.
Each flow path has some unique contaminants related to the
materials originally disposed of in each trench. The
northwest flow path is characterized by high concentrations
of halogenated, aromatic, and water soluble solvents,
phenols, ketones, acids, and esters suggesting origins from
styrene copolymers, phenol-formaldehyde resins, and other
polymers. Chlorinated phenols appear to be unique to this
plume. In addition, there is a large number of tentatively
identified volatile and semivolatile compounds (TICs), which
are compounds not on the Target Compound List (TCL) that
were identified in this flow path, consisting of xylenes,
naphtha-based solvents and other petroleum hydrocarbons (see
Appendix A of the Feasibility Study).
As much as 72,000 parts per billion (ppb) of halogenated
volatile organics, 45,000 ppb of aromatic volatile organics,
and 100,QOO ppb of water soluble organics were detected in
the northwest ground water flow path. Up to 6,900 ppb of
total semivolatile organics were also found. In the

-------
RECORD OF DECISION SUMMARY
picillo Farm site
Page 9
organic contaminants range from 2,500 ppb (compounds on the
TCL list) to 22,500 ppb if TICs, xylenes, and naphtha
solvents are included.
The southwest flow path is characterized by halogenated and
aromatic solvents, but contains several unique compounds
including 1,2-dichloropropane, 2,6-dinitro-4-
trifluoromethylphenol, and 1-chloro-2-nitro-4(trifluoro)-
methylbenzene. The chloro-, fluoro-, and nitrobenzenes may
be related to dye wastes. Concentrations of total volatile
and semivolatile compounds in the southwest flow path (near
the slit trench) are approximately 7,000 ppbwith
halogenated organics representing approximately 90 percent
of the contaminants.
All contaminants found to date in ground water have been
dissolved. However, the high concentrations of dissolved
organic compounds found suggest the possible presence of
undissolved liquid chemicals referred to as dense non-
aqueous phase liquids (DNAPLs). Although shallow ground
water was found to flow generally to the west, the bedrock
topography and fractures may facilitate migration of any
existing DNAPLs in both westerly and easterly directions.
Pesticides and PCBs are not significant ground water
contaminants at the Site. Several pesticides were detected
sporadically at trace concentrations, typically in the 0.02
to 0.10 ppb range. PCBs were detected in only one
monitoring well at a concentration of 3.2 ppb. Metals
concentrations were found at near naturally occurring
levels. Slightly elevated levels of some naturally-
occurring metals close to source areas are possibly due to
enhanced solubility caused by sOlvents,in ground water.

The current aerial extent of ground water contamination in
overburden and shallow bedrock is approximately 35 acres.
Based on the level of total volatile organic (TVO) .
contamination, the Feasibility Study (FS) divided the ground
water contamination into three regions in order to develop
remedial technologies most appropriate for each level of
contaminant concentration.. The regions of the plume are
referred to as the source (TVO greater than 10,000 ppb),
concentrated (TVO from 1,000 to 10,000 ppb) and dilute (TVO
less than 1,000 ppb) regions. .
Residences located in the area of the site use bedrock and
overburden wells for drinking water purposes. The
residential well sampling of a total 26 wells did not
indicate contamination above the limits of EPA Drinking

no contamination detected. Two of the residential wells,
those on the picillo Farm property, extend only into the
shallow overburden aquifer. The majority of the other
residential wells are screened in the deep bedrock aquifer.
B.
Soil
An analysis of historical aerial photography, a magnetometer
survey, a soil gas survey, and test pit excavation were
conducted on suspect areas, mostly outside of the disposal
area, to supplement earlier studies. Results of these
investigations verified that all drums were removed during
earlier removal actions.
Sixty six (66) soil borings of various depths were drilled
in and near historic trench locations and outside of the
disposal area for installation of monitoring wells. Soil
samples were collected at periodic intervals and were
analyzed at an on-site laboratory. Approximately 20 percent
of these samples were split and sent to CLP laboratories for
confirmatory analysis. The chemical analysis indicated that
significant subsurface soil contamination concentrations
still exist in and near the northeast, northwest, and west
trenches. Lower contamination concentrations exist in the
south and slit trenches. A majority of the soil
contamination was found 10 to 30 feet below the ground
surface.
A variety of volatile organic compounds (VOCs) and
semivolatile organic compounds (SVOCs) were detected in and
near the former disposal trenches (Appendix A, Figures 8 .
through 11). In the vicinity of the northeast trench, up to
235,000 ppb of halogenated and aromatic VOCs were detected.
Up to 4,600 ppb of water soluble VOCs were also detected.
Highly contaminated soils were discovered as deep as 44 feet
near this trench. Phenols (up to 31,000 ppb) and 1,2-
dichlorobenzene (up to 22,000 ppb) were the two SVOCs
detected at the highest concentrations in and near this
trench.
Several aromatic and halogenated VOCs were also detected
from samples collected in and near the northwest and west
trenches. The most contaminated sample collected during the
soil boring program revealed the presence of greater than
12,500,000 ppb (1.25%) of halogenated VOCs and 41,000,000
ppb (4.1%) of aromatic VOCs. Significant concentrations of
phenols and 1,4-dichlorobenzene were also detected in the

-------

The sampling in the vicinity of the northeast, northwest,
and west trenches indicates that "fingering" of DNAPLs
contamination may have occurred, meaning that thin zones of
high concentrations of contamination have spread out from
the trenches. In at least the northwest and west trenches,
this contamination has migrated back into the clean soil
which had been used to backfill excavated trenches in the
1980s. The most highly contaminated soil samples were.
collected from the vadose zone just above the water table in
and adjacent to these trenches.
Analysis of near-surface and surface soil samples collected
throughout the former disposal area indicated lower
concentrations of VOC contamination. The highest
concentration of total VOC contamination was less than 120
ppb and the total SVOC concentrations typically were
detected at less than 25,000 ppb. Based on the soil boring
program, the volume of soil contaminated with VOCs and SVOCs
was estimated to be approximately 131,000 cubic yards, most
of which was found in a vicinity of historic trench
locations.
In general, pesticides and PCBs were found sporadically
throughout the Site mostly at the surface at low
concentrations, with exception of the former PCB pile
location. The highest PCB concentration was detected in a
surface soil sample collected at the former PCB pile
location, where 28,000 ppb was measured. PCBs were also
measured (up to 7,000 ppb) in the drainage ditch that
originates adjacent to the PCB pile and directs runoff to
the northwest corner of the disposal area. PCBs were not
detected in most other surface soil samples collected around
the Site. The volume of surface soil contaminated with PCBs
was estimated to be approximately 600 cubic yards (Appendix
A, Figures 12 and 13). .
Metals concentrations in soils were found at near naturally
occurring levels.
c.
Surface Water and Sediment
The disposal area is situated west of a surface water
divide, which is approximately coincidental with the access
road to the disposal area. The surface water hydrology in
the vicinity of the disposal area is dominated by west-
directed runoff into Unnamed Swamp and Great Cedar Swamp and
the southwest-flowing drainage patterns of Unnamed Swamp.
Surface water discharge measurements at the outlet of
Unnamed Swamp were recorded during the second and third

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 12
during high and low runoff flow periods.
Two quarterly rounds of surface water and sediment samples
were collected at more than twenty (20) locations within two
square miles study area. A third round of surface water
samples was collected at six (6) locations previously
showing significant contamination. The pattern of surface
water and sediment contamination corresponds with the
patterns of the most concentrated ground water plumes
(Appendix A, Figures 14 and 15). The most contaminated
surface water and sediment sampling locations are at the
ground water discharge points of the contaminated ground
water plume originating in the disposal area. Lower
concentrations of surface water contamination were observed
north of the disposal area along a seepage slope, and at the
edge of Unnamed Swamp.
Although similar to the contaminant profile observed in
ground water, the profile of surface water and sediment
contamination includes higher relative concentrations of
degradation products (i.e., chloroethane, vinyl chloride,
1,1-dichloroethane), especially at the edge of Unnamed
Swamp. The highest total VOCs concentration detected in
surface water was 4,400 ppb. SVOCs were also detected in
surface water, but at much lower concentrations than VOCs,
usually less than 100 ppb. The primary SVOCs appear to be
phenols, phthalates, and halogenated aromatics. Similar
SVOCs were detected in sediments at concentrations up to
3,990 ppb of total SVOCs. Total SVOCs in sediment sometimes
exceeded the total VOCs detected in the same samples.
Significant concentrations of polynuclear aromatic
hydrocarbons (PAHs) and ethers, in addition to those
mentioned above, were also detected in sediment. The
sediments in Unnamed Swamp remain contaminated at depth,
where sediments from 18 to 24 inches had similar contaminant
concentrations as the samples from 0 to 6 inches depth.
Pesticides and PCBs do not appear to be significant
contaminants in surface water and sediment, although these
chemicals were detected sporadically around the Site. The
highest concentration, 27 ppb of the pesticide Methoxychlor,
was detected in a sediment sample collected from a seep in
the southwest portion of the site. Additional PCB sampling
will be conducted in surface water and sediment to verify
the presence of PCBs in these media.

Metals concentrations were found at near naturally occurring
levels. Slightly elevated levels in surface water and
sediment of some naturally-occurring metals are possibly due

surface water.
D.
Air
Ambient air monitoring conducted immediately above the
ground surface and in the breathing zone at the most
contaminated surface water locations indicated the presence
of volatile organic contaminants (l,l-dichloroethane and
cis-1,2-dichloroethylene) at one ground water discharge
point for the northwest plume directly above a seep. The
levels did not exceed federal or state air quality
standards.
A complete discussion of Site characteristics can be found in the
RI Report in Sections 2, 3 and 4.
VI.
SUMMARY OF SITE RISKS
A Baseline Human Health Risk Assessment (HHRA) and Ecological
Risk Assessment (ERA) were performed to estimate the probability
and magnitude of potential adverse human health and environmental
effects from exposure to contaminants associated with the site.
The public health risk assessment followed a four step process:
1) contaminant identification, which identified those hazardous
substances which, given the specifics of the site were of
significant concern; 2) exposure assessment, which identified
actual or potential exposure pathways, characterized the
potentially exposed populations, and determined the extent of
possible exposure; 3) toxicity assessment, which considered the
types and magnitude of adverse health effects associated with
exposure to hazardous substances, and 4) risk characterization,
which integrated the three earlier steps to summarize the
potential and actual risks posed by hazardous substances at the
site, including carcinogenic and non-carcinogenic risks. The
results of the public health risk assessment for the picillo Farm
site are discussed below followed by the conclusions of the
environmental risk assessment.
A.
Human Health Risk Assessment (HHRA)
sixteen (16) media-specific exposure zones were delineated
based on chemical concentration, geographic location, and
hydrologic characterization. A detailed explanation of
rational and delineation of each zone can be found in
section 2 of the HHRA. In summary, (1) two exposure zones
have been identified for grOund water - source and distant
zones; (2) two soil exposure areas were identified - source
and outlying, and each exposure area was divided vertically
into two zones - surface and subsurface; and (3) five

sediment (Appendix A, Figures 16 through 18).
All chemicals identified at the site for which dose response
data were available, approximately 80 compounds listed in
Table 1 found in Appendix B of this Record of Decision, were
evaluated in the risk assessment. These Tables are compiled
for each exposure zone within each environmental media. In
addition, approximately 450 tentatively identified compounds
(TICs) were found during the remedial investigation sampling
program. TICs are compounds that were not on the Target
Compound List (TCL) , but were identified as peaks on .
chromatograms during sample analyses. A complete list of
TICs is presented in Appendix E of the HHRA.
The contaminants evaluated in the risk assessment constitute
a representative subset of contaminants identified or
tentatively identified at the Site during the Remedial
Investigation. The contaminants evaluated in the risk
assessment represent potential site related hazards based on
toxicity, concentration, frequency of detection, and
mobility and persistence in the environment. A summary of
the health effects of each of the contaminants of concern
can be found in Section 2.6 and Appendix B of the HHRA.
Potential human health effects associated with exposure to
the contaminants of concern were estimated quantitatively or
qualitatively through the development of several
hypothetical exposure pathways. These pathways were
developed to reflect the potential for exposure to hazardous
substances based on the present uses, potential future uses,
and location of the Site. The population identified as a
potential receptor in the current land use scenario is
trespasser population which is considered to visit the site
for recreational activities (e.g., biking, hiking, swimming,
and wading). Although no residences are currently located
in the contaminated area, several residences are located
near the Site, as close as 1,300 feet from the disposal
area.
Future potential land use scenarios include potential
residential and trespasser populations, since it is possible
that residential housing will be constructed in the
contaminated area at a future time and recreational
activities are expected to be similar to the current land
use scenario. The following is a brief summary of the
exposure pathways evaluated. A more thorough description
can be found in Section 4 of the HHRA.
Under future potential residential land use, exposure to

-------
RECORD OF DECISION SUMMARY

as drinking water, inhalation of vapors as showering and
basement seepage and dermal contact. The exposure pathway
through ingestion as drinking water was quantified and the
remaining exposure pathways were estimated qualitatively.
Ingestion rates of 2 liters per day for adults and 1 liter
per day for children were presumed over 30 years, which
includes 6 years as young child and 24 years as an adult.
Exposure to contaminated soil was considered through
incidental ingestion, dermal contact and inhalation of
particulates for the current trespassing population. The
same exposures plus inhalation of volatiles were considered
for future residential population. Out of these exposure
pathways, ingestion and dermal contact were evaluated
quantitatively. Dermal contact and incidental ingestion of
soils for trespassers were evaluated for older child/young
adult (age 6-15 years) who may be exposed 50 days per year
for 10 years. For potential residents, dermal contact and
incidental ingestion of soils were evaluated for 30 years of
exposure including 6 years as young child and 24 years as an
adult who may be exposed 150 days per year.
Exposure to sediment was considered for a trespassing
scenario under both, current and future land use. The
exposure pathways for sediment included incidental
ingestion, dermal contact and inhalation while wading.
Incidental ingestion and dermal contact with sediment were
evaluated quantitatively to reflect an older child/young
adult who may wade in the shallow areas of the swamp, seeps
and pond for 50 days (under current land use scenario) and
100 days (under future land use scenario) each summer for 10
years.
Exposure to surface water was evaluated similar to sediment.
For the swamp and pond, incidental ingestion and dermal
contact while swimming and wading was evaluated. For the
shallow seeps, only dermal contact while wading was
considered. Incidental ingestion and dermal contact with
surface water reflect older child/young adult swimming 20
days each summer (under current land use scenario) and 50
days (under future land use scenario) each summer for 10
years. Additional dermal contact while wading was evaluated
for older child/young adult considering 50 days and 75 days
under current and future land uses respectively for 10
years.
For the residential population, ingestion of fish caught
fr9m the open water of the swamp and the pond was evaluated
under a current land use scenario. Use of surface water as

-------
RECORD OF DECISION SUMMARY

inhalation while showering) in addition to the fish
ingestion, was considered under a future residential land
use scenario. Ingestion as drinking water and fish
ingestion were quantitatively evaluated. Exposure from
ingestion of fish was calculated assuming 10 meals per year
for 30 years. Ingestion of surface water as drinking water
was evaluated utilizing the same exposure parameters as for
ingestion of ground water.
For each pathway evaluated, an average and a reasonable
maximum exposure estimate were generated corresponding to
exposure to the average and the maximum concentration
detected in that particular medium.
Excess lifetime cancer risks were determined for each
exposure pathway by multiplying the exposure level with the
chemical specific cancer slope factor. Cancer slope factors
have been developed by EPA from epidemiological or animal
studies to reflect a conservative "upper bound" of the risk
posed by potential~y carcinogenic compounds. That is, the
true risk is unlikely to be greater than the risk predicted.
The resulting risk estimates are expressed in scientific
notation as a probability (e.g., 1 x 10-6 for 1/1,000,000)
and indicate (using this example), that an average
individual is not likely to have greater than a one in a
million chance of developing cancer over 70 years as a
result of site-related exposure as defined to the compound
at the stated concentration. Current EPA practice considers
carcinogenic risks to be additive when assessing exposure to
a mixture of hazardous substances.
The hazard index was also calculated for each pathway as
EPA's measure of the potential for non-carcinogenic health
effects. A hazard quotient is calculated by dividing the
exposure level by the reference dose (RfD) or other suitable
benchmark for non-carcinogenic health effects for an
individual compound. Reference doses have been developed by
EPA to protect sensitive individuals over the course of a
lifetime and they reflect a daily exposure level that is
likely to be without an appreciable risk of an adverse
health effect. RfDs are derived from epidemiological or
animal studies and incorporate uncertainty factors to help
ensure that adverse health effects will not occur. The
hazard quotient is often expressed as a single value (e.g.,
0.3) indicating the ratio of the stated exposure as defined
to the reference dose value (in this example, the exposure
as characterized is approximately one third of an acceptable
exposure level for the given compound). The hazard quotient
is only considered additive for compounds that have the same

-------
RECORD OF DECISION SUMMARY
picillo Farm site
Page 17
hazard index (HI). (For example: the hazard quotient for a
compound known to produce liver damage should not be added
to a second whose toxic endpoint is kidney damage).
Table 2 of Appendix B depicts the carcinogenic and non-
carcinogenic risk summary for the contaminants of concern in
ground water, soil, sediment and surface water evaluated to
reflect present and potential future exposure pathways
corresponding to the average and the reasonable maximum
exposure (RME) scenarios. A detailed summary of the
carcinogenic and non-carcinogenic risk for each contaminant
of concern for each exposure pathway can be found in Table 3
of Appendix B. .
Carcinogenic and non-carcinogenic risk estimates were
evaluated relative to the EPA's risk management criteria.
The carcinogenic risks or ILCR (Incremental Lifetime Cancer
Risks) are compared to a risk range of 10-6 ("point of
departure") to 10-4. Non-carcinogenic risks, or HIs (Hazard
Indices), are compared to a value of one (1), below which
adverse health effects from exposures are not anticipated.
Highlighted values in Table 2 of Appendix B represent those
risk estimates which exceed the upper limit of the risk
range (10-4) for an ILCR or HI of one (1).
Of the exposure media for which risk estimates were
calculated, ingestion of ground water as drinking water, and
ingestion of fish and surface water from the swamp as
drinking water are associated with significant human health
risks due to exceedance of EPA's risk management criteria
for both the average and the reasonable maximum exposure
scenarios. For ingestion of ground water, 1,2-
dichloroethane, chloroform and beryllium were the chemicals
contributing significantly to the overall carcinogenic risk
estimate. Chloroform was the largest contributor to the
non-carcinogen risk estimate. For ingestion of surface
water and fish from the swamp, vinyl chloride, 1,1-
dichloroethene, benzo(a)pyrene, Aroclor 1260 and Aroclor
1248 (PCBs) were significant contributors to the
carcinogenic risk estimate and cis-1,2-dichloroethene and
manganese were the highest contributors to the non-
carcinogenic risk estimate. Current carcinogenic risk is
primarily contributed to ingestion of fish contaminated with
PCBs. However, these PCBs were each detected once in the
surface water at the swamp, approximately 600 feet west and
northwest of the disposal area, while none of the monitoring
wells west and northwest of the Site showed PCB
contamination in ground water. Additional PCB sampling will
be conducted in surface water and sediment to verify the

-------
RECORD OF DECISION SUMMARY

In addition, approximately 24 contaminants exist in ground
water at concentrations that were found to exceed both state
and federal maximum contaminant levels (MCLs). Of the
compounds detected in surface water, approximately 26 exceed
MCLs or Rhode Island Ambient Water Quality Standards.
Potential risks associated with ground water and surface
water contamination are primarily attributed to the presence
of VOCs and SVOCs.
Exposure to soil and sediment through direct contact are not
considered to pose significant human health risks as the
risks from exposure to these media are within EPA's
acceptable risk range of 10-4 to 10-6 for ILCRs and less
than one (1) for HIs. The soil contamination, however,
provides leaching of contaminants into the ground water at
concentrations greater than MCLs and is considered a media
of concern because the residual contamination is a
continuing source of contamination for the ground water.
B.
Ecological Risk Assessment (ERA)
A baseline Ecological Risk Assessment was performed to
estimate the magnitude of potential adverse effects on
wildlife from exposure to contaminants associated with the
surface water, sediments, and soil.
The following four indicator species were selected for
evaluation in the ERA because of their sensitivity and
exposure to contaminants and expected use of the habitats at
and nearby the Site:
.
Green Frog;
American Woodcock;
Short-tailed Shrew; and
Mink.
.
.
.
In addition, risks were estimated for the entire aquatic
community of both the aquatic and wetland zones of exposure.
Four distinct zones of ecological exposure were identified
to reflect the diversity of ecosystems and habitats of the
study area. These four exposure zones are:
.
Terrestrial areas within the disposal area;
Terrestrial areas outside the disposal area;
Wetland habitats that are not permanently flooded; and
Permanently flooded aquatic habitats.

Potential effects on the wildlife from exposure to site

the characterization of the site and the study area. The
primary pathways are direct contact and food-chain exposure.
Methods for evaluation included a comparative analysis of
contaminant concentrations with regulatory criteria and
guidelines, food-chain contaminant uptake modeling, and the
performance of a chronic sediment toxicity test for two
invertebrate species.
No obvious symptoms of vegetation or animal stress were
observed on site or in the larger study area. No adverse
effects were observed from chronic toxicity tests performed
using sediment collected from the site.
However, food chain contaminant uptake calculations
indicated unacceptable ecological risks for the American
Woodcock and Short-tailed Shrew due to the presence of PCBs
and to a lesser degree pesticides in the surface soils
within the disposal area (in the drainage ditch and at the
former PCB pile location). A small component of the total
risk was from exposure to lead, a non-site related
contaminant.
Aquatic species and green frog tadpoles were estimated to be
at unacceptable risk from exposure to surface water, which
in some cases exceeded water quality criteria (Appendix B,
Table 4). Sediments in localized areas outside the disposal
area also were estimated to pose a risk to indicator species
through consumption of contaminated food items. Because
most of the risk is from non-site related contaminants, and
the contaminated sediments are found in localized areas, it
is felt that this pathway may represent a conservative risk
scenario that may not warrant direct intrusion into the
wetland habitat.
Actual or threatened releases of hazardous substances from this
site, if not addressed by implementing the response action
selected in this ROD, may present an imminent and substantial
endangerment to public health, welfare, or the environment. The
human health risk assessment identified ground water and surface
water media as posing unacceptable health risks. In order to
prevent migration of contaminants into ground water and for the
ground water to. be restored to drinking water standards, soil
needs to be remediated. Surface soil within the disposal area
and surface water are the media posing unacceptable risk to
environmental receptors. Therefore, all these media are
designated as media of concern and will be targeted as the focus

A.
statutory Requirements/Response Objectives
Under its legal authorities, EPA's primary responsibility at
Superfund sites is to undertake remedial actions that are
protective of human health and the environment. In
addition, Section 121 of CERCLA establishes several other
statutory requirements and preferences, including: a
requirement that EPA's remedial action, when complete, must
comply with all federal and more stringent state
environmental standards, requirements, criteria or
limitations, unless a waiver is invoked; a requirement that
EPA select a remedial action that is cost-effective and that
utilizes permanent solutions and alternative treatment
technologies or resource recovery technologies to the
maximum extent practicable; and a preference for remedies in
which treatment which permanently and significantly reduces
the volume, toxicity or mobility of the hazardous substances
is a principal element over remedies not involving such
treatment. Response alternatives were developed to be
consistent with these Congressional mandates.
Based on preliminary information relating to types of
contaminants, environmental media of concern, and potential
exposure pathways, remedial action objectives were developed
to aid in the development and screening of alternatives.
These remedial action objectives were developed to mitigate
existing and future potential threats to public health and
the environment. These response objectives were:
.
Restore contaminated ground water to drinking water
standards, and to a level that is protective of human
health and the environment, as soon as practicable;
.
Restore contaminated surface water to drinking water
standards and ambient water quality criteria (AWQCs),
and to a level that is protective of human health and
the environment, as soon as practicable;
.
Prevent or mitigate the continued release of hazardous
substances to the ground water and surface water from
the soils by reducing the concentration of contaminants
in the soil so that the concentration in ground water
and surface water will not exceed drinking water
standards or AWQCs and will not pose a risk to human
health and the environment;
.
Prevent or mitigate releases of contaminants to the

B.
Technology and Alternative Development and Screening
CERCLA and the NCP set forth the process by which remedial
actions are evaluated and selected. In accordance with
these requirements, a range of alternatives was developed
for the site.
with respect to source control, the RIfFS developed a range
of alternatives in which treatment that reduces the
toxicity, mobility, or volume of the hazardous substances is
a principal element. This range included an alternative
that removes or destroys hazardous substances to the maximum
extent feasible, eliminating or minimizing to the degree
possible the need for long term management. This range also
included alternatives that treat the principal threats posed
by the Site but vary in the degree of treatment employed and
the quantities and characteristics of the treatment
residuals and untreated waste that must be managed; and a no
action alternative.
With respect to ground water response action, the RIfFS
developed a limited number of remedial alternatives that
attain site specific remediation levels within different
timeframes using different technologies; and a no action
alternative.
As discussed in Section 3.0 of the Feasibility Study, the
RIfFS identified, assessed and screened technologies based
on implementability, effectiveness, and cost. These
technologies were combined into source control (SC) and
management of migration (MM) alternatives. Section 3.0 of
the Feasibility Study presented the remedial alternatives
developed by combining the technologies identified in the
previous screening process in the categories identified in
Section 300.430(e) (3) of the NCP. The purpose of the
initial screening was to narrow the number of potential
remedial actions for further detailed analysis while
preserving a range of options. Each alternative was then
evaluated and screened in Section 4.0 of the Feasibility
Study.

process.

DESCRIPTION OF ALTERNATIVES
This Section provides a narrative summary of each alternative
evaluated. A detailed assessment of each alternative can be
found in Section 4.0 of the Feasibility Study.
The time frames and costs of each SC and MM alternative are
presented in this ROD as part of a cleanup scenario, when a
source control and management of migration alternative are
combined for implementation together. A description of the
institutional controls and environmental monitoring program is
presented as part of the description of MM alternatives, but
applies to both, SC and MM portions of the cleanup scenario.
A.
Source Control (SC) Alternatives Analyzed
The source control alternatives analyzed for the site
include the following:
.
SC-l - No Action;
.
SC-2 - In-Situ thermally enhanced vapor extraction of
the soil to remove volatile and semivolatile
contaminants;
.
SC-3 - In-Situ vapor extraction of soils to lower risk
due to volatile emissions and to reduce volume of soil
that has to be remediated followed by excavation and
thermal desorption of the contaminated soil to remove
the remaining volatile and semivolatile contaminants;
and
.
SC-4 - In-Situ vapor extraction of soils to lower risk
due to volatile emissions and to reduce volume of soil
that needs to be remediated followed by excavation and
off-site incineration of the soil to remove the
remaining volatile and semivolatile contaminants.
The existence of DNAPLs within the soil and the source and
concentrated plume area will be further investigated during
the design studies. EPA may perform periodic reviews of
advances in soil and ground water cleanup technology to
determined if new techniques have been developed to

-------

whether any modifications to the remedy are appropriate.
Additional sampling of sediment and surface water for PCBs
will be performed as part of a pre-design to verify the
presenc~ of PCBs and to determine if remediation of PCB-
contaminated sediment is required.
SC-l No Action
Alternative SC-1 is evaluated in detail in the FS to serve
as a baseline for comparison with the other remedial source
control alternatives under consideration. Under this.
alternative, no action would be taken. Natural attenuation
of the contaminated soil would occur over time through
diffusion, biological degradation, and abiotic degradation.
The No Action response does not supersede the March 1987 ROD
for the picillo Farm Site, and therefore, any requirements
of that document would continue to apply, including the
maintenance of the disposal area, the drainage ditch, and
the fence around the disposal area.
The No Action alternative would require reviews at least
every five years to monitor contaminant concentrations over
time and to determine whether cleanup activities would be
required. The five-year reviews would continue until no
contaminants remain at the Site above levels that would
allow for unrestricted use and unlimited exposure.
The volatile soil contamination would persist for
approximately 500 years and the semivolatile contamination
would persist for approximately 400 years.

SC-2 In-situ Thermallv Enhanced Vagor Extraction

This alternative is designed to treat the contamination in
the subsurface soils while in place. A thermally enhanced
vapor extraction system would be installed on-site in the
areas where the soil contamination exceeds the soil cleanup
levels established to prevent migration of contaminants into
the ground water. The vacuum extraction system would be
operated in conjunction with a dewatering system. The

air stripping described in alternatives MM-2 and MM-3.
With the enhanced soil vapor extraction (SVE) technology,
heated air would be pumped through contaminated soil to
remove volatile and semivolatile contaminants. Vapor
extraction wells and hot air injection wells would be
installed in the area near the disposal trenches. The
volatilized contaminants would be treated by a thermal
oxidation system such as catalytic oxidizer. The resultant
compounds would be water, carbon dioxide and hydrochloric
acid. The hydrochloric acid would be removed using a .
caustic scrubber to adsorb the acid gases and to produce a
brine solution which would be sent off-site. Typical
destruction efficiency for the catalytic oxidizer would be
greater than or equal to 97% for TCE and 99% for DCA, TCA,
and other hydrocarbons. The scrubber would typically remove
98% of the acid gases.
The effluent water and air streams from the treatment plant
and ambient air would be sampled and analyzed as necessary
to ensure that ARARs are met. In addition, treatment
residuals would be disposed of in compliance with ARARs.
At the design stage, a pilot test for a limited number of
vacuum extraction and air injection wells would be conducted
to optimize the system prior to full scale operation. The
pilot test would assist in determining design
characteristics such as the precise number and location of
vapor extraction and air injection wells; site specific
vapor flow rates; radius of influence measurements;
contaminant recovery rates; site specific subsurface air
temperatures; precise dewatering techniques and specific
water and off-gas treatment options, to ensure that the SVE
system most effectively captures and removes the
contamination. During design and implementation of the
thermally enhanced vapor extraction, other methods may be
evaluated to enhance the effectiveness of the system in
meeting cleanup levels. Such methods may include other
enhancements to vapor extraction, such as radio frequency
heating, steam injection and air sparging.
Although this alternative may potentially impact the
wetlands by dewatering the seeps and part of the Unnamed
Swamp, based on current data, the water balance is expected
to be maintained. Evaluation of provisions to maintain the
water balance in the area would be performed at the design
stage. .

(approximately 600 cubic yards) and disposed of at an off-
site, TSCA-regulated, treatment, storage, and disposal
facility. Excavation and storage of PCB contaminated soil
would be performed in compliance with ARARs.
The thermally enhanced SVE system is estimated to require
approximately 3 years to pilot test, develop a full-scale
design and achieve operational conditions. The operation
time needed for the enhanced SVE to meet cleanup levels is
estimated to be 3 years based on a computer model described
in Appendix L of the FS which was used to calculate the
contaminant removal rates.

SC-3 Thermal Desorption
This alternative involves the excavation and on-site
treatment of the contaminated subsurface soil through the
use of thermal desorption. Prior to excavating the soils,
however, the volatile contamination would be reduced by
approximately 60% using in-situ vapor extraction and thermal
oxidation as described in the alternative SC-2. Vapor'
extraction would be used in order to reduce the potential
short-term risk to the local residents and workers from the
VOCs emitted during excavation. After vapor extraction,
approximately 94,000 cubic yards of contaminated soil (a
total of 240,000 cubic yards, which includes clean soil
above the contamination) would be excavated and transported
to the on-site thermal desorption system where the soils
would be heated in a system such as rotary drum thermal
desorber. The volatilized contaminants will be destroyed in
a thermal oxidation unit, such as catalytic oxidizer.
After the soil is treated or shown to meet the cleanup
levels for soils, it would be returned to the trenches where
it was removed. The area would be regraded and revegetated.
The effluent water and air streams from the SVE and thermal
desorption treatment plants and ambient air would be sampled
and analyzed as necessary to ensure that ARARs are met. In
addition, treatment residuals would be disposed of in

to minimize emissions during excavation, thermal desorption
and backfilling.
This alternative may potentially impact the wetlands by
dewatering the seeps and part of the Unnamed Swamp.
However, based on current data, the water balance is
expected to be maintained. Evaluation of provisions to
maintain the water balance in the area would be performed at
the design stage.
The PCB contaminated surface soil, in the drainage ditch and
at and near the former PCB pile, would be excavated
(approximately 600 cubic yards) and disposed of at an off-
site, TSCA-regulated, treatment,' storage, and disposal
facility. Excavation and storage of PCB contaminated soil
would be performed in compliance with ARARs.
This alternative would be implemented in two phases: 1) the
implementation of vapor extraction system; and 2) the
excavation and thermal desorption and excavation and
disposal of the PCB contaminated surface soil. The vapor
extraction system is estimated to take 2 years to design,
construct and achieve operational conditions and 3 years to
operate. While the vapor extraction system is operating,
the thermal desorption system would be designed and
installed in order to be operational when 60% of volatile
contaminants are removed. The excavation and thermal
desorption is estimated to operate for 2 years. Overall,
this alternative would take two years to design and install
and 5 years to operate to achieve cleanup levels.

*
The off-site incineration alternative involves excavation of
the contaminated soil and transportation of the soil to an
off-site incinerator facility. Prior to excavating the
soils, however, the VOC contamination would be reduced by
approximately 60% using in-situ vapor extraction and thermal
oxidation as described in alternative SC-2. Vapor
extraction would be used in order to reduce the potential

approximately 94,000 cubic yards of contaminated soil (a
total of 240,000 cubic yards which includes clean soil above
the contamination) would be excavated and transported off-
site for incineration. The excavated areas would then be
backfilled with clean fill material.
The effluent water and air streams from the SVE plant and
ambient air would be sampled and analyzed as necessary to
ensure that ARARs are met. In addition, treatment residuals
would be disposed of in compliance with ARARs. Engineering
controls would be used to minimize emissions during
excavation, loading of trucks and backfilling.

This alternative may potentially impact the wetlands by
dewatering the seeps and part of the Unnamed Swamp.

(approximately 600 cubic yards) and disposed of at an off-

This alternative would take place in two phases: 1) the
implementation of the vapor extraction system; and 2) the
excavation and off-site incineration of the contaminated
soil, including disposal of the PCB-contaminated surface
soil. The vapor extraction system is estimated to take 2
years to design, construct and achieve operational
conditions and 3 years to operate. While the vapor
extraction system is .operating, the excavation of the
contaminated soil would be planned to begin when 60% of
volatile contaminants have been removed. The excavation and
transport of the soils off-site is estimated to proceed for
approximately 7 months. Overall, this alternative would
take two years to design and install and 4 years to operate. .

Management of Migration (MM) Alternatives Analyzed
The development of the management of migration alternatives
was done using the available information, historical
knowledge of the Site area, and generally applied scientific
approaches to solving hydrogeologic issues. Extraction well
locations and pumping rates for all alternatives are
approximate. The estimated times for cleanup of the aquifer
are based on a model which uses a mass balance approach (see
Appendix K of the FS).
Design studies will be performed prior to cleanup to
determine the number, pumping rate, and placement of
extraction wells that will most effectively capture,
recover, and treat the contaminants. Similarly, the exact
location and method of discharge for treated water may be
altered if negative impacts on wetlands in the area are
predicted through the design studies or become apparent
after the cleanup has started.
The RI presented evidence that petroleum solvents may be
present near the northwest and west trenches. Sampling and
analysis for total petroleum hydrocarbons (TPH) in ground
water would be required as part of the design to verify
their presence and to ensure that the ground water and soil
treatment system are able to effectively treat the
additional contaminants.
Management of migration alternatives address contaminants
that have migrated from the original source of .
contamination. At the Picillo Farm Site, contaminants have
migrated via ground water in westerly, northwesterly and
southwesterly directions from the disposal trenches and have
discharged to the Unnamed Swamp and Great Cedar Swamp.
Contamination that has migrated to the overburden and
shallow bedrock will be withdrawn using wells placed to
remove the ground water in that zone. If any contamination
is present in the less fractured deeper zone of bedrock, it
is expected to diminish as ground water remediation
progresses in the shallow bedrock and overburden. Water
quality in this deeper zone will be monitored, and if it
appears to be deteriorating, EPA will address the need for
expanding the extraction and treatment systems.
Because the surface water contamination is directly related
to the ground water contamination, by remediating the ground
water to interim cleanup levels, the surface water will be
remediated to meet the surface water cleanup levels.

MM-l No Action
Alternative MM-l would include a minimal comprehensive
sampling and analysis program. Quarterly sampling events
are proposed to address ground water, surface water and
sediment. Site reviews would be performed at least every
five years to decide whether the program should be expanded,
reduced, or discontinued. This alternative is referred to
as the Limited Action alternative in the FS report.
Natural attenuation of the contaminated ground water and
soil would occur over time through dilution, biological
degradation, and abiotic degradation. The No Action
response would not supersede the March 1987 ROD for the
Picillo Farm Site and, therefore, any requirements of that
document continue to apply.
The environmental monitoring program would be implemented to
evaluate the rate of natural attenuation. The monitoring
program would include installation of additional deep.
bedrock monitoring wells. Environmental monitoring would
include periodic sampling of selected monitoring wells,
residential wells, surface water and sediment. All
monitoring data would be evaluated annually and a report
prepared at least every five years. Based on results of the
evaluation, the monitoring program, including sampling of
residential wells, would be modified as necessary.
Without implementation of an active treatment source control
alternative, the volatile contamination in ground water
would persist for approximately 500 years and the
semivolatile and nonvolatile contamination would exist for
approximately 400 years. With an active treatment source

contamination is estimated to persist for 40 years and the

The No Action alternative for groundwater has been retained
and evaluated in two scenarios: one with an active source
treatment and one without an active source treatment (as
presented below). This was done to establish a baseline to
which all other alternatives are to be compared as required

Alternative MM-2: UV/Oxidation or Air StriDDina of the
Source and Concentrated Reqions and Air strippinq of the
Dilute Reqion
Alternative MM-2 involves the extraction and treatment of
ground water in the source and concentrated regions of the
plume in order to limit the effect the residual
contamination has on the entire aquifer. Alternative MM-2
would also remediate the dilute region of the plume as
quickly as possible by pumping and treating the ground water

-------
RECORD OF DECISION SUMMARY
picillo Farm site
Page 31
EPA has selected a combination of two treatment options in
Alternative MM-2 to treat the contaminated ground water in
the source and concentrated regions of the plume:
UVjOxidation and carbon adsorption and air stripping and
carbon adsorption. Based on the cost estimate in the FS,
the UVjOxidation treatment system is more cost-effective
than the treatment option of air stripping and carbon
adsorption for the source and concentrated regions of the
plume. However EPA is proposing a second treatment option,
air stripping and carbon adsorption, so that if the cost
estimates change to the extent that air stripping becomes
more cost-effective than UVjOxidation, EPA has the option of
selecting air stripping and carbon adsorption.
Extraction wells would be installed in the source and
concentrated regions of the ground water plume. Ground
water from the dewatering wells would be mixed with the
water from the containment wells and treated in the ground
water treatment system. Additional extraction wells would
be installed in the dilute portion of the plume (Appendix A,
Figure 21). In order for the wells most effectively capture
and recover the contaminated ground water, the precise
number, pumping rate, and placement of extraction wells
would be determined during the remedial design phase.
After pretreatment, i.e., equalization and metal
precipitation systems, ground water would be pumped to the
UVjoxidation system and/or air stripper. Ground water from
the source and concentrated regions of the plume and
dewatering operations would be treated by UVjoxidation or
air stripping. Ground water from the dilute portion of the
plume would be treated by air stripping.
In the UVjoxidation system, hydrogen peroxide, ozone, or a
combination of both, would be added to the ground water.
The ground water then would be exposed to ultraviolet light
in a reactor. Based on a laboratory-scale treatability
study (Laboratory-Scale Treatability Study, Arthur D.
Little, Inc., June 10, 1993), up to 99% of the organic
contamination would be destroyed. The ultraviolet light
causes the hydrogen peroxide or ozone to form molecules
that, because they are highly reactive, break down the VOCs
and SVOCs into water, carbon dioxide, and harmless chloride
salts. The remaining contaminants would be treated by
carbon adsorption. If ozone is used, air from the treatment
system would pass through a catalytic decomposer such as
activated carbon filters to convert the remaining ozone to
oxygen and to remove the contaminants prior to discharging

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 32
For air stripping and carbon adsorption, the only difference
in the treatment train will be the use of an air stripper in
place of a uv/oxidation unit. All other components of the
MM-2 alternative would remain the same. In the air
stripping unit, contaminated water would be contacted with
clean air to volatilize the majority of the volatile organic
contaminants. Based on the pilot studies (RI/FS, Tighe and
Bond/SCI, August 1983) the air stripper would remove 90% of
VOCs, and the remaining 10% of VOCs and SVOCs would be
removed by the carbon adsorption (RI/FS, Tighe and Bond/SCr,
August 1983 and Laboratory-Scale Treatability Study, Arthur
D. Little, Inc., June 10, 1993). The contaminated air would
be passed through activated carbon to remove VOCs before the
air is released to the atmosphere. The contaminated carbon
would be periodically regenerated, a process in which the
contaminants are destroyed and the carbon is recycled. The
resultant treated water would be reinjected into the aquifer
or discharged to surface water.
Alternative MM-2 may impact wetlands by dewatering the seeps
and part of the Unnamed Swamp by extracting water in the
dilute region of the plume. Based on current data, because
of the large volume of water withdrawn and the proximity of
the extraction wells to the Unnamed Swamp, it would be very
difficult to maintain the water balance in the Unnamed Swamp
and the Great Ceder Swamp at current levels. Erosion
control techniques during construction of the reinjection
system would minimize long-term impacts on wetlands.
While the ground water is being remediated, institutional
controls would be implemented to restrict access around the
areas of active soil remediation and to restrict use of the
contaminated ground water and surface water where the
concentrations of the compounds of concern are greater than
the cleanup levels. The restrictions would remain in place
until the cleanup levels are met.
The environmental monitoring program would be implemented to
evaluate the performance of the treatment system, the rate
of natural attenuation, and the overall effectiveness of the
remedy. The monitoring program would include installation
of additional deep bedrock monitoring wells. Environmental
monitoring would include periodic sampling of selected
monitoring wells, residential wells, surface water and
sediment. All monitoring data would be evaluated annually
and a report prepared at least every five years. Based on
the results of the evaluation, the monitoring program,
including sampling of residential wells, would be modified

The effluent water and air streams from the treatment
plant(s) and ambient air would be sampled and analyzed as
necessary to ensure that ARARs are met. In addition,
treatment residuals would be disposed of in compliance with
ARARs.
Based on current data, the estimated time for restoration of
the aquifer in the concentrated and source regions of the
plume, including source control, is approximately 20 years
for volatile and 10 years for semivolatile contamination.
In the dilute region of the plume, the volatiles and.
semivolatiles will persist for approximately 4 and 8 years,
respectively, after implementation of the source control
remedy.

B.
Comparative Analysis of Alternatives
A detailed analysis was performed on the alternatives using
the nine evaluation criteria in order to select a site
remedy. The following summarizes the comparison of each
alternative strength and weakness with respect to the
nine evaluation criteria.
1. Overall Protection of Human Health and the
Environment
with the exception of alternative SC-l, No Action, all
source control alternatives evaluated are considered
protective of human health and the environment.
Alternatives SC-2 would provide overall protection to
human health and the environment through treatment of
all the contaminated soils in the disposal area.
Alternatives SC-3 and SC-4 would also provide
protection of human health and the environment by
excavating and treating the contaminated soil.
Treatment of the contaminated soils would reduce

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
paqe 38
enabling the ground water to be restored to drinking
water standards more quickly. Excavation and off-site
disposal of the PCB contaminated surface soil in all
active treatment SC alternatives would provide
protection of human health and the environment.
Alternative SC-l, No Action does not utilize adequate
controls to prevent exposure to the contaminants
because contaminants would remain in soil and continue
to be released into ground water for about 500 years.
Alternative MM-3, as well as alternative MM-2, if
implemented in conjunction with any of the active
treatment SC alternatives, would provide protection to
human health and the environment through capture and
treatment of the contaminated ground water and through
limiting discharge of the contaminated ground water to
surface water, and through institutional controls
restricting the use of the contaminated ground water
and surface water.
Alternative MM-l (No Action) would not provide adequate
controls to prevent exposure to the contaminated ground
water during the restoration time period. without the
implementation of an active treatment Source Control
alternative, the aquifer would likely be returned to
its beneficial use in approximately 500 years. with
the implementation of an active treatment Source
Control alternative, the aquifer would likely be
returned to its beneficial use in approximately 40
years.
2. Compliance with Applicable or Relevant and
Appropriate Requirements (ARARs)
with the exception of the No Action alternatives (Se-I)
and (MM-l) , all of the other alternatives that received
detailed analysis in the FS would ultimately meet
Federal and State ARARs. Implementation of MM-2 or MM-
3 with any of the active treatment source control
alternatives would achieve compliance with ARARs in
approximately 20 years. Without implementation of any
active treatment source control alternative,
implementation of either MM-2 or MM-3 would achieve
ARARs compliance in approximately 500 years. The No-

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 39
would allow continued release of contaminants from
source areas to the ground water. Implementation of
No-Action alternative MM-l in conjunction with any of
the active treatment SC alternatives would not achieve
compliance with all ARARs for 40 years. Joint
implementation of MM-l and SC-l would not achieve
compliance with all ARARs for 500 years.
3.
Long-Term Effectiveness and Permanence
All SC alternatives (except SC-l, No Action) provide
similar degrees of long-term effectiveness and
permanence since treatment of all hazardous materials
is provided prior to disposal. The No Action SC
alternative (SC-l) would not provide effective or
permanent reductions to long-term risk.
All of the MM alternatives, with the exception of MM-l
(No Action), provide similar degrees of long-term
effectiveness and permanence since all of the active
treatment alternatives provide for treatment of the
source and concentrated plume. The long-term risks
associated with implementing alternatives MM-2 and MM-3
would be eliminated in approximately 20 years, if any
of the active treatment SC alternatives are also
implemented.
Alternative MM-3 relies on natural attenuation of the
dilute portion of the plume which is estimated to take
approximately 20 years, when the source and
concentrated regions of the plume would be captured and
treated. Alternative MM-2 utilizes treatment of the
dilute portion of the plume which is estimated to take
approximately 8 years. The restoration time for the
source and concentrated regions of the plume is
approximately 20 years in both alternatives. Thus, the
overall restoration time for MM-2 and MM-3 alternatives
are the same.
Extraction and treatment technologies used in the
alternatives utilizing treatment are generally reliable
and achieve a high degree of effectiveness and
permanence. Treatment technologies in SC-2 and SC-3,
SVE and thermal desorption, destroys contaminants on
site, while alternative SC-4, includes remediation of
contaminated soils by vapor extraction on-site and
subsequent off-site incineration. In all three active
treatment SC alternatives, excavation and off-site
disposal of the PCB contaminated surface soil provides

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 40
alternatives, both air stripping with carbon adsorption
and UVjoxidation with carbon adsorption permanently
destroy the contaminants removed from the ground water.
UVjoxidation destroys more contaminants on site; the
alternative using air stripping destroys the
contaminants when the activated carbon is regenerated.
If no active treatment SC alternative is implemented,
the No Action MM alternative (MM-l) would not provide a
long-term, effective reduction in risks for 500 years.
If an active treatment SC alternative is implemented
the No Action MM alternative (MM-l) would not provide a
long-term, effective reduction in risks for 40 years.
4. Reduction of Toxicity, MObility, or Volume through
Treatment
All of the source control alternatives, with the
exception of SC-l (No Action), reduce the extent of
toxicity, mobility, and volume of the contamination
since all would employ treatment prior to disposal.
SC-4 would provide the greatest reduction since it
involves incineration of all hazardous wastes. The
off-site incinerator would destroy approximately 99% of
the contamination. Alternatives SC-2 and SC-3 provide
a lesser degree of treatment than incineration.
Between 97% and 99% of the contamination would be
oxidized in a catalytic oxidation system. All three
active treatment source control alternatives are
estimated to remove approximately 380,000 lbs of
contamination from 130,000 cubic yards of soil to be
treated. Alternative SC-l would not reduce the
toxicity, mobility, or volume of the contamination.
Both MM-2 and MM-3 reduce the extent of toxicity,
mobility, and volume of the contamination by use of a
ground water extraction and treatment system.
UV/oxidation is expected to remove approximately 99% of
the contamination. The remaining contaminants would be
treated by activated carbon. Air stripping is expected
to remove 90% of VOCs from the contaminated ground
water; the remaining approximately 10% of VOCs and
SVOCs would be removed by the activated carbon. MM-2
would provided the greatest reduction since it involves
the collection and treatment of the dilute,
concentrated and source regions of the plume.
Alternative MM-3 would capture and treat ground water
from the source and concentrated regions and would
limit migration of contaminants outside the source and

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 41
would allow the level of toxicity to decrease over time
in the dilute region through natural attenuation. MM-l
(No Action) would not reduce the toxicity, mobility, or
volume of the contamination through treatment.
s.
Short-Term Effectiveness
Alternatives SC-2, SC-3, and SC-4 would be effective in
the short term. However, the excavation of the soils
in close proximity to nearby residents and the high
concentration of VOCs in the soils cause a potential
for release of contaminants during the excavation
activities and a concern for short-term risk to the
community and workers. To minimize the potential for
contaminant emissions during cleanup related activities
in alternatives SC-3 and SC-4, vapor extraction would
be performed prior'to excavating the soils and
approximately 60% of the contaminants would be removed,
but the actual air emissions that would result for the
excavation would still pose an unknown risk to the
community. Alternative SC-4 would also require the
use of a large number of trucks to transport the
contaminated soil off-site. This activity would impact
the residents surrounding the Picillo Farm site.
Implementation of alternative SC-2 potentially could
release small amount of vapors and fugitive dusts
during excavation of the PCB contaminated surface soils
and installation of the wells system. Since
alternative SC-l does not achieve protection of human
health or the environment, it is also not effective in
the short term.
Alternative MM-3 would have no adverse impacts on human
health. Alternative MM~3 could present a short-term
impact to the wetlands by modifying the water balance
in the area and by disturbing wetlands for construction
of pipes and wells. To minimize the impact, a water
balance would be maintained during extraction and
recharge of ground water and erosion controls would be
implemented during the construction activities.
Alternative MM-2 presents greater short-term risks to
the environment than MM-3, since it could potentially
dewater the wetlands surrounding the picillo Farm site
because of the need to extract and treat the ground
water in the dilute region of the plume in the
immediate proximity to the wetlands. Since alternative
MM-l does not achieve protection of human health or the
environment, it is also not effective in the short

-------

Page 42
The treatment methods in all alternatives are not
expected to have any adverse impact on the local
community, nor on properly trained workers.
6.
Implementability
Alternative SC-2 (thermally enhanced vapor extraction)
is an innovative technology having been tested only at
a few sites; therefore, it would have to be pilot
tested prior to implementation. The treatment
technology used in alternative SC-3 (thermal
desorption) is readily implementable and has been
successfully implemented at other sites. Alternative
SC-4 may be difficult to implement due to the volume of
soil that would have to be shipped to a hazardous waste
disposal facility for incineration and limited ability
of local roads to handle high-volume heavy truck
traffic. The No Action alternative SC-1 raises no
issues regarding implementability since it requires no
technical or administrative actions.
The MM-2 and MM-3 alternatives are implementable. The
extraction/treatment systems (installation of the
ground water extraction wells, UV/oxidation system, air
stripper and carbon adsorption) are well-developed
technologies and all have been used successfully at
other sites. The No action alternative MM-1 can also
be implemented and would use established and reliable
well drilling, monitoring, and analytical procedures.
7.
Cost
Alternative SC-4 would be the most expensive of all of
the alternatives with an estimated total cost of
approximately $101,200,000. The second most expensive
source control alternative would be alternative SC-3
with estimated total costs of approximately
$23,900,000. Alternative SC-2 has the lowest cost of
the active treatment source control alternatives with
an estimated total cost of approximately $4,100,000.
The above costs are for the SC alternatives when they
are implemented in conjunction with an active treatment
MM alternative. The No action alternative SC-l
requires no cost.
Alternative MM-2 is the most expensive management of
migration alternative with estimated total costs of
approximately $14,200,000 (UV/oxidation and air
stripping) or $20,300,000 (alternative air stripping).

-------
RECORD OF DECISION SUMMARY
picillo Farm site
page 43
$11,600,000 (UV/oxidation system) or $18,900,000
(alternative air stripper). The No action alternative
MM-1 would require the least amount of money with
estimated total costs of approximately $3,700,000, if
implemented in conjunction with an active treatment
source control remedy, or $4,300,000, if No Action
alternative SC-1 is implemented.
These costs are estimates made during the Feasibility
Study that are expected to provide accuracy of +50
percent to -30 percent. In calculating present worth a
discount rate of 5 percent was used.

State Acceptance
The State's comments on the RI/FS and Proposed Plan, as
received during the public comment period, and the
EPA's responses to the comments are summarized in the
Responsiveness Summary in Appendix 0 of the ROD.
In general, the State supported the preferred
alternative set forth in the Proposed Plan. Among
other specific issues, the State commented on the
desirability of a residential well monitoring program
at specific frequency; the need for a sentinel well
system west and east of the Site and possible better
delineation of the plume; the need for routine
monitoring and options for improvement to the systems;
and the need to maintain institutional controls. The
State of Rhode Island' Letter of Concurrence, provided
in Appendix C of the ROD, documents the State's
position on the selected remedy.
9.
Community Acceptance
The comments received from the community on the RIfFS
and the Proposed Plan during the public comment period,
and the EPA's responses to the comments are also
summarized in the Responsiveness Summary in Appendix 0
of the ROD.
In general, comments received from the community did
not raise serious objections to the preferred
alternative set forth in the Proposed Plan. One of the
cementers, however, asked EPA to consider active
remediation of the entire plume. Main concerns of the
community were related to the residential well
monitoring and safety issues during construction and
operation of the remedy. Several potentially

THE SELECTED REMEDY
The remedy for the Picillo Farm Superfund Site selected to
address the remaining contamination at the Site includes: source
control alternative SC-2 and management of migration alternative
MM-3. A detailed description of the cleanup levels and the
selected remedy is presented below.
A.
Interim Ground Water Cleanup Levels
Interim cleanup levels have been established in ground water
for all contaminants of concern identified in the Baseline
Risk Assessment found to pose an unacceptable risk to either
public health or the environment. Interim cleanup levels
have been set based on the ARARs (e.g., Drinking Water
Maximum Contaminant Level Goals (MCLGs) and MCLs) as
available, or other suitable criteria described below.
Periodic assessments of the protection afforded by remedial
actions will be made as the remedy is being implemented and
at the completion of the remedial action. At the time that
Interim Ground Water Cleanup Levels identified in the ROD
and newly promulgated ARARs and modified ARARs which call
into question the protectiveness of the remedy have been
achieved and have not been exceeded for a period of three
consecutive years, a risk assessment shall be performed on
the residual ground water contamination to determine whether
the remedial action is protective. This risk assessment of
the residual ground water contamination shall follow EPA
procedures and will assess the cumulative carcinogenic and
non-carcinogenic risks posed by exposure to ground water
(e.g., ingestion of ground water from domestic water usage).
If, after review of the risk assessment, the remedial action
is not determined to be protective by EPA, the remedial
action shall continue until either protective levels are
achieved, and are not exceeded for a period of three
consecutive years, or until the remedy is otherwise deemed
protective. These protective residual levels shall
constitute the final cleanup levels for this Record of
Decision and shall be considered performance standards for
any remedial action.
The aquifer under the Site is a Class IIB type aquifer,
which is a potential source of drinking water. Therefore,
MCLs and non-zero MCLGs established under the Safe Drinking

Interim cleanup levels for known, probable, and possible
carcinogenic compounds (Classes A, B, and C) have been
established to protect against potential carcinogenic.
effects and to conform with ARARs. Because the MCLGs for
Class A & B c6mpounds are set at zero and are thus not
suitable for use as interim cleanup levels, MCLs and.
proposed MCLs have been selected as the interim cleanup
levels for these Classes of compounds. Because the MCLGs
for the Class C compounds are greater than zero, and can
readily be confirmed, MCLGs and proposed MCLGs have been
selected as the interim cleanup levels for Class C
compounds. . .
Interim cleanup levels for Class 0 and E compounds (not
classified, and no evidence of carcinogenicity) have been
established to protect against potential non-carcinogenic
effects and to conform with ARARs. Because the MCLGs for
these Classes are greater than zero and can readily be
confirmed, MCLGs and proposed MCLGs have been selected as
the interim cleanup levels for these classes of compounds.
In situations where a promulgated State standard is more
stringent than values established under the Safe Drinking
Water Act, the State standard was used as the interim
cleanup level. In the absence of an MCLG, an MCL, a
proposed MCLG, proposed MCL, State standard, or other
suitable criteria to be considered (i.e., health advisory,
state guideline) an interim cleanup level was derived for
each compound having carcinogenic potential (Classes A, B,
and C compounds) based on a 10-6 excess cancer risk level
per compound considering the ingestion of ground water from
domestic water usage. In the absence of the above standards
and criteria, interim cleanup levels for all other compounds
(Classes 0 and E) were established based on a level that
represent an acceptable exposure level to which the human
population including sensitive subgroups may be exposed
without adverse affect during a lifetime or part of a
lifetime, incorporating an adequate margin of safety (hazard
quotient = 1) considering the ingestion of ground water from
domestic water usage. If a value described by any of the
above methods was not capable of being detected with good
precision and accuracy or was below what was deemed to be
the background value, then the practical quantification
limit or background value was used as appropriate for the
Interim Ground Water Cleanup Level.

carcinogenic and non-carcinogenic contaminants of concern

While these interim cleanup levels are consistent with ARARs
or suitable TBCcriteria for ground water, a.cumulative risk
that could be posed by these compounds may exceed EPA's
goals for remedial action. Consequently, these levels are
considered to be interim cleanup levels for ground water.
At the time that these Interim Ground water Cleanup Levels

of the remedy have been achieved and have not been exceeded
for a period of three consecutive years, a risk assessment

All Interim Ground water Cleanup Levels identified in the
ROD and newly promulgated ARARs and modified ARARs wnich
call into question the protectiveness of the remedy and the
protective levels determined as a consequence of the risk
assessment of residual contamination, must be met at the
completion of the remedial action at the points of
compliance throughout the plume (defined here as
approximately 35 acres of contaminated ground water), as
indicated on Figure 22 of Appendix A). EPA has estimated
that these levels will be obtained within approximately 20
years. The ability to meet this time frame would be
dependent on the effectiveness of the source control remedy;
the ability to contain the contamination in the source and
concentrated regions of the plume while the source control
remedi is implemented; and whether DNAPLs exist, and to what
extent that they exist, in the bedrock.
B.
Soil Cleanup Levels
Based upon data developed in the RI and the HHRA, remedial
measures to address risk associated with possible exposure
to source soils are not warranted because present and future
risks are within or below EPA's acceptable carcinogenic risk
range or for the non-carcinogens generally below a Hazard
Index of one. However, available data suggest that area
soils are a source of release of VOCs to ground water. This
phenomenon may result in an unacceptable risk to those who
drink contaminated ground water in the foreseeable future.
Therefore, cleanup levels for soils were established to
prqtect the aquifer from potential soil leachate. The
Summer's Leaching Model was used to estimate residual soil
levels that are not expected to impair future ground water
quality. The interim cleanup levels for ground water were
used as input into the leaching model. If the predicted
protective soil level was not capable of being detected with
good precision and accuracy, then the practical
quantification limit was selected as the cleanup level for
soils. The table below summarize the soil cleanup levels
required to protect public health and the aquifer and were
developed for the ground water contaminants of concern

These cleanup levels in soils are consistent with ARARs for
ground water, attain EPA's risk management objective for
remedial actions, and have been determined by EPA to be
protective. These cleanup levels must be met at the'
completion of the remedial action throughout all soils in
the areas near the former disposal trenches at varying
depths, with the majority of soil contamination found 10 to
30 feet below ground, with some contamination found at
dept~s of more than 50 feet below the ground~ as indicated
on the Figures 8 through 11 and Figure 19 in Appendix A.
The volume of soil contaminated with compounds at
,concentrations above their ground water protection limits is
estimated to be 130,000 cubic yards.
..
Cleanup levels for surficial soils were developed to reduce
risks associated with the exposure of environmental
receptors (Table 2B). The cleanup level for PCBs was
developed using a multi-zone foraging scenario presented in
the ecological risk assessment which represents a probable
foraging scenario for American Woodcock and Short-tailed
Shrew populations. Based on the multi-zone scenario, which
includes area-weighed foraging in the disposal area, in the
uplands, and in the wetlands, the PCBs cleanup level of
1,300 ug/kg was selecteq for the Site for the protection of

The cleanup levels for PCBs must be met throughout the
surface soil in a vicinity of the former PCB pile and the

volume of surface soil contaminated with PCBs is estimated
to be approximately 600 cubic yards.

Surface Water Cleanup Levels
Cleanup levels have been established in surface water for
all contaminants of concern identified in the Baseline Risk
Assessment £ound to pose an unacceptable risk ~o either
public health or the environment. Cleanup levels have been
set to be protective of human health and aquatic life based
on the ARARs as available, or other suitable criteria
described below.
The Unnamed Swamp and unclassified surface waters at the
Site have been designated by the State of Rhode Island as
Class A waters, which are a potential source of drinking
water. Therefore, MCLs and non-zero MCLGs established under
.the Safe Drinking Water Act and Ambient Water Quality
Criteria (AWQCs) established under the Clean Water Act are
ARARs.
Cleanup levels for known, probable, and possible
carcinogenic compounds (Classes A, B, and C) have been
established to protect against potential carcinogenic
effects to human health and adverse effects to the
environment, and to conform with ARARs. Because the MCLGs
for Class A & B compounds are set at zero and are thus not
suitable for use as cleanup levels, MCLs and proposed MCLs
have been selected as the cleanup levels for these Classes
of compounds. Because the MCLGs for the Class C compounds
are greater than zero, and can readily be confirmed, MCLGs
and proposed MCLGs have been selected as the cleanup levels
for Class C compounds. In situations were AWQC is more
stringent than MCL and proposed MCL or non-zero MCLG and
proposed non-zero MCLG, the AWQC was used as the cleanup
leve~ for these classes of compounds.
Cleanup levels for Class D and E compounds (not classified,
and no evidence of carcinogenicity) have been established to
protect against potential non-carcinogenic effects to human
health and adverse effects to the environment, and to
conform with ARARs.. . Because the MCLGs for these Classes are
greater that zero and can readily be confirmed, MCLGs and
proposed MCLGs have been selected as the cleanup levels for
these classes of compounds. In situations were AWQC is more

AWQC was used as the cleanup level for these classes of
compounds.
In situations where a promulgated State standard for surface
'water quality is more stringent than values established
under the Safe Drinking Water Act or the Clean Water Act,
the State standard was used as the cleanup level. In the
absence of an MCLG, an MCL, a proposed MCLG, proposed MCL,
AWQC, State standard, or other suitable criteria to be .
considered, a cleanup level was derived for each compound
having carcinogenic potential (Classes A, B, and C
compounds) based on a 10-6 excess cancer risk level per
compound considering the ingestion of surface water from
domestic water usage; dermal contact with surface wateriand
incidental ingestion of surface water. In the absence of
the above standards and criteria, cleanup levels for all
other compounds (Classes D and E) were established based on
a level that represent an acceptable exposure level to which
the human population including sensitive subgroups may be
exposed without adverse affect during a lifetime or part of
a lifetime, incorporating an. adequate margin of safety
(hazard quotient = 1) considering the ingestion of surface
water from domestic water usage; dermal contact with surface
water and incidental ingestion of surface water. If a value
described by any of the above methods was not capable of
being detected with good precision and accuracy, then the
practical quantification limit was used as appropriate for
the Surface Water Cleanup Level. Also, where the background
concentration for a compound was greater than the most
stringent standard, the background concentration was used
for the Surface Water Cleanup Level. .

RECORD OF DECISION SUMMARY

Page SS
These cleanup levels for surface water must be met at the
completion of the remedial action at the points of
compliance in all surface waters, including the Unnamed
Swamp and other wetlands and open water bodies on the Site.
Because the surface water contamination is directly related
to the ground water contamination, by remediating the ground
water to interim cleanup levels, the surface water will be
remediated to meet the surface water cleanup levels. This
can be shown by mixing the water that infiltrates into the
ground water above the plume and estimating the resulting
contaminant concentration. Based on curr~nt data,the water
infiltrating into the ground water plume would reduce the.
contaminant concentration by approximately 20 percent from
the disposal area to the discharge into surface water.
Therefore, if the ground water in the disposal area has a
contaminant concentration equal to or less than the ground
water interim cleanup levels, the water discharging into the
swamp and the seeps will have contaminant concentration
equal to or less than the surface water cleanup levels.
Sediment cleanup levels are not being established at this
time. No active cleanup of the sediment is being proposed.
Additional sampling of surface water and sediment to verify
the presence of PCBs in surface water and sediment will be
performed prior to or during the design.
D.
Description of Remedial components
The selected remedy, consists of a combination of source
control alternative SC-2 and management of migration
alternative MM-3, to address the soil, ground water and
surface water contamination. The selected remedy has the
following seven components: 1) treatment of contaminated
soils by thermally enhanced vapor extraction and catalytic
oxidation; 2} excavation and .off-site disposal of surface
soils contaminated with PCBs; 3) extraction of contaminated
ground water in the source and concentrated regions of the
plume and natural attenuation of the dilute region of the
plume; 4) treatment of the extracted ground water by
ultraviolet (UV)/oxidation and carbon adsorption or air
stripping and carbon adsorption; 5) recharge of the treated
ground water into the aquifer; 6) long-term environmental
monitoring and periodic reviews of the Site; and 7)
institutional controls. Each component is described below.
1) Treatment of contaminated soils bY thermallY enhanced
vapor extraction and catalytic oxidation

This alternative is designed to treat the contamination in

-------
RECORD OF DECISION SUMMARY

need fot excavating the soils and exposing the
contamination. To meet this objective, a thermally enhanced
vapor extraction system would be installed on-site in the
areas where the soil contamination exceeds the soil cleanup
levels established to reduce migration of contaminants into
the ground water. The ground water table in these areas
would be lowered by pumping and hot air would be injected
into the soils to enhance the volatilization of both VOCs
and SVOCs. The volatilized organics would then be collected
in vapor extraction wells and piped to ~ thermal oxidation
system, such as catalytic oxidation unit, where the organics
would be oxidized. The extracted ground water would be
treated by UVjOxidation or air stripping (see Treatment of
the extracted ground water by ultraviolet (UV)joxidation and
carbon adsorption or air stripping and carbon adsorption
component of the remedy). Access to the areas of active
remediation would be restricted by a fence or application of
an equivalent method to secure the Site for the protection
of human health and equipment.
The vacuum extraction system would be operated in
conjunction with a dewatering system. A Dual Vapor
Extraction (DVE) well system could be installed to lower the
water table and extract contaminants from the soil. In the
DVE system, the vapor extraction wells would extend to the
depth where the volatile compounds are to be extracted. The
dewatering wells, smaller in diameter, would extend through
the soil vapor extraction wells below the lowered water
table. The ground water pumped from the dewatering wells
would be collected and pumped to the treatment building in a
pipeline to be buried below frost depth or application of an
equivalent method that would prevent po~ential freezing
problems. .
To enhance the volatilization of the contaminants, ambient
air would be compressed and heated to approximately 600
degrees F. The air would then be injected into the
contaminated soil through evenly spaced, multiple stainless
steel injection wells. The temperature of the air extracted
from the ground is estimated to increase from 55 degrees F
to approximately 100 degrees F. Multiple PVC vapor
extraction wells would be used to collect the volatilized
contaminants (Appendix A, Figure 23). Vapor extraction
wells would be installed in and near the area of
contaminated soil and would be evenly spaced so that their
radius of influence overlap. The extraction wells would be
capable of having a submersible pump installed at the bottom
for dewatering if the DVE system is. selected during the
design studies. The dewatering, vapor extraction and air

a sufficient depth to allow for the removal of residual
contamination from the soil in the area near the water
table, and the remediation of any DNAPLs that may be present.
in the highly fractured shallow bedrock. The system will
also allow for the upward flow of ground water from the
bedrock to capture dissolved contamination, once the ground
water table is lowered.
In order to enhance recovery of the vapor extraction system,
a temporary cap would be installed over the area. The cap.
would be installed after the wells were in place and would
consist of an impermeable membrane with clay or soil top
layer.
A vacuum pump would remove the contaminated air from the
soil. From the vacuum pump the contaminated gas would be
piped to a thermal oxidation unit to be located in a
treatment building within the disposal area. The first step
in the system would be a vapor liquid separator. The
liquids removed from the air stream would be sent off-site
for treatment and disposal. The air stream would then be
passed through a heat exchanger to recover approximately 50%
of the heat from the tre~ted gas in the effluent of the
thermal oxidation system. Following the heat exchanger, the
temperature of the gas stream would be raised further in the
preheater and then the contaminants would be destroyed in
the thermal oxidation system. The resultant compounds would
be water, carbon dioxide and hydrochloric acid (formed due
to the presence of chlorinated solvents).
After the destruction of the contaminaDts, the gas would be
passed through the heat exchanger again, this time to lower
the temperature of the treated gas stream. Acid gases from
the oxidation of the chlorinated hydrocarbons would then be
absorbed and neutralized in a caustic scrubber. The
scrubber would generate a brine solution that would be
disposed of off-site. From the scrubber, the treated. air
would then be released to the atmosphere.

2) Excavation and off-site disposal of surface soil
contaminated with PCBs
The PCB contaminated surface soil, in the drainage ditch and
near the former PCB pile, will be excavated (approximately
600 cubic yards) and disposed of at an off-site, TSCA-
regulated, treatment, storage, and disposal facility. The
exact amount of soil to be excavated is to be determined
based on the sampling and analysis for PCB contamination to
be performed during the design stage and the excavation

3) Extraction of contaminated qround water in the source and
concentrated reqions of the plume and natural attenuation of
the dilute reqion of the plume
Ground water from the source and concentrated regions of the
ground water plume would be collected using a multi-well
extraction system located in the source and concentrated.
region of the plume (Appendix A, Figure 23). The ground
water extraction wells would be constructed with stainless
steel or equivalent well casing to minimize degradation of
the well. Destruction of PVC well casing has been noted at
the 5ite, necessitating the use of the higher grade casing
material. Each of the wells would be drilled into the
shallqw bedrock. The ground water pumped from these wells
would be collected and pumped to the treatment building in a
pipeline to be buried below frost depth or application of an
equivalent method that would prevent potential freezing
problems.
The dilute region of the plume would be isolated from the
source contamination by using the extraction system as
described above to provide active containment. The dilute
portion of the plume would then be allowed to naturally
attenuate. Natural attenuation is the reduction of
contamination levels through three main processes:
diffusion; biodegradation; and physical and chemical
(abiotic) degradation. The isolation and natural
attenuation of the dilute region of the plume would be
enhanced by the reinjection of the treated ground water
downgradient of the extraction wells.
4) Treatment of the extracted qround water bY ultraviolet
(UV)/oxidation and carbon adsorption or air strippinq and
carbon adsorption
The extracted ground water would be combined with water from
the dewatering operations and pumped into an equalization
tank to be located in the ground water treatment building
within. the disposal area; The equalization tank would also
be used to remove any pure contaminants or solids which
would be drummed and sent to an off-site facility.

From the equalization tank the ground water would be pumped
to a metal precipitation unit where manganese, iron and
other inorganic (metallic) compounds would be removed. The
metals removal system would minimize the chances for
adversely affecting the UV/oxidation system and would also
reduce any elevated metal concentrations in the ground water
to naturally occurring levels. The metal sludge would be

treatment prior to disposal.

After the metal precipitation system, the pH of the ground
water would be adjusted and the ground water would be pumped
to the UV/oxidation system and/or air stripper. Hydrogen
peroxide, ozone, or a combination of both, would be added to
the ground water. The ground water then would be exposed to
ultraviolet light in a reactor. The ultraviolet light
causes the hydrogen peroxide or ozone to form molecules
that, because they are highly reactive, break down the VOCs
and SVOCs into water, carbon dioxide, and harmless chloride
salts. Based on the laboratory treatability study, a 60
minute retention time would degrade approximately 99% of the
organic contamination. .
After treatment by the UV/oxidation system, the ground water
would be passed through activated carbon filters to remove
the remaining contaminants. If ozone is used, air from the
treatment system would also pass through a catalytic
decomposer such as activated carbon filters to convert the
remaining ozone to oxygen and to remove the contaminants
prior to discharging to the atmosphere.
The only component of the preferred alternative that could
change is the implementation of an air stripper instead of
the UV/oxidation unit. Air stripping and carbon adsorption
would be used to treat the contaminated ground water
collected from the ground water extraction wells and the
dewatering system. All other components of the remedy would
remain the same. In the air stripping unit, contaminated
water would be countercurrently contacted with clean air to
volatilize the majority of the volatile organic
contaminants. Based on the pilot studies performed by Tighe
and Bond, the air stripper would remove about 90% of VOCs,
and the remaining 10% of VOCs and SVOCs would be removed by
the carbon adsorption treatment. Since either of these
treatment options (UV/Oxidation and air stripping with
carbon adsorption) will effectivelyach~eve the treatment
levels~ the decision on which system will be used will be
based upon more refined data and cost analysis during the
design. .

For the air stripping option, the vapor phase activated
carbon filter would be preceded by a heater to raise the
temperature and to reduce the relative humidity of the
contaminated air stream, thereby increasing the adsorptive
capacity of the carbon filter. The contaminated carbon
would be periodically regenerated for reuse. Based on the
data collected during the design and the system operation,

destruction, may be considered by EPA.
The remedial investigation of the source and concentrated
regions of ground water suggests that DNAPLs may be present.
The source control part of the remedy, enhanced SVE, is .
expected to effectively remove and treat the DNAPLs that may
exist. The ground water extraction wells will .initially
contain that portion of the plume where any DNAPLs may be
found so that the remainder of the contaminated aquifer and
surface water can be restored to their beneficial uses. EPA
will collect and periodically assess monitoring data and
periodically review advances in ground water cleanup
technology to determine if new techniques have been
developed to effectively remediate DNAPLs conditions and
whether any. modifications to the remedy are appropriate to
provide more effective attainment of cleanup levels.
.5) Recharae of the treated around water into the aauifer
The resultant treated water would be pumped from the ground
water treatment building to reinjection wells or discharged
into surface waters to maintain the water balance in the
Unnamed Swamp and the Great Ceder Swamp at current levels.
The piping to the reinjection wells would be buried below
frost depth or would incorporate an alternative design that
would minimize the potential for winter freeze-ups.
6) Lona-term environmental monitorina and periodic reviews
of the Site
The environmental monitoring program would be implemented to
evaluate the performance of the treatment system, the rate
of natural attenuation, and the overall effectiveness of the
remedy. The remedy would include installation of additional
deep bedrock monitoring wells to monitor for dissolved.
contamination in the deep bedrock northeast and west of the
disposal area and to act as early warning wells for
contamination approaching the residential wells. If
contamination is found to spread, an evaluation of the
effectiveness of the entire ground water extraction and
treatment system will be performed. Based on this
evaluation, adjustments or modifications to the ground water
extraction system will be implemented to prevent or limit
further contaminant. migration.
Selected ground'water monitoring wells would be sampled on a
quarterly basis for .VOCs and SVOCs. Selected surface water
and sediments locations would be sampled for VOCs and SVOCs
on at least an annual basis. Ground water, surface water

metals, PCBs and pesticides. TICs positively identified in
the RI and TICs from the monitoring program would be
periodically analyzed for in the subsequent sampling rounds.
Since evidence exists for the presence of petroleum solvents
near the northwest and west trenches, the total petroleum
hydrocarbons (TPH) analysis would need to be performed at
least annually. Residential wells in the area would be
monitored annually during the initial startup period of
cleanup activities. The number and location of weils
sampled and the frequency of sampling and analysis,
including sampling of residential wells, may be changed
based upon the evaluation of the sampling data results.

The influent and effluent from the treatment-plants would be
monitored as necessary to determine efficiency of the
treatment systems and to ensure compliance with ARARs. Air
omonitoring would be done at the treatment plants as
necessary to ensure that air emissions are in compliance
with ARARs. °
The details of the monitoring program would be developed
during remedial design to be tailored to the specifics of
the design. Additional monitoring wells and surface water
and sediment sampling locations may be needed to evaluate
the extent of the contamination over time and to monitor for
changes in the preferential contaminant movement and
discharges to the surface water system.
A soil monitoring program to demonstrate compliance with
soil cleanup levels and a performance monitoring program for
the enhanced SVE system would also be performed to determine
if the SVE system is working effectively. Results will be
evaluated to determine future operating parameters of the
system.
Selected bedrock and overburden wells would be monitored
upon initiation of remedial design until completion of the
remedial design.
Reports assessing the results of the sampling and analysis
events would be done after every sampling event. All
monitoring data would be evaluated during the implementation
of the remedial action to ensure that response objectives
are achieved. Monitoring data would beoevaluated to
determine effectiveness o~o the remedy, suggest remedy
improvements arid to refine predicted cleanup time.
Modifications to the remedial action, including the
evaluation and possible implementation of advances in ground
water cleanup technology may also require changes in

Institutional controls
Institutional controls could include access restrictions
around areas of active soil remediation and restrictions on
use of the contaminated ground water and surface water. The
institutional controls would remain in place until the
cleanup levels are met. The objective of the institutional
controls shall be to insure that no activities take place at
the Site which either affect implementation of the selected
remedy or cause exposures to hazardous substances.
8)
Remedial Desiqn Issues
At the design stage, a pilot test for the enhanced SVE
utilizing a limited number .of vacuum extraction and air
injection wells would be conducted to optimize the system
prior to full scale operation. Design components such as,
the precise number and location of vapor extraction and air
injection wells, site specific vapor flow rates, radius of .
influence measurements, contaminant recovery rates, site
specific subsurface air temperatures, precise dewatering
techniques (e.g., trenches or horizontal wells), and
specific water and off-gas treatment options, so that the
SVE. system most effectively captures and removes the
contamination would be determined based on the pilot test
results.
During design and implementation of the thermally enhanced
vapor extraction, other methods may be evaluated to enhance
the effectiveness of the system in meeting cleanup levels.
Such methods may include other enhancements to vapor
extraction, such as radio frequency heating, steam injection
and air sparging.
Design studies would be performed for the dewatering
operation to determine system parameters such as: the time
period needed to dewater the area; exact depth of .
dewatering; need for DVE system; number and location of
dewatering wells; radius of influence; and pumping rates and
operational mode (partial vs. simultaneous).
The dewatering of the soils for the enhanced SVE operation
and extraction of the ground water in the source and
concentrated regions of the plume may potentially impact the

of the remedy on the water table in the area. Similarly,

water and the method of discharge for the treated water

contamination to be performed during the design stage and
the excavation activities. .
Design studies would be performed to determined the precise
number, pumping rates and placement of ground water

data. . .
Approximately 450 compounds were tentatively identified in
the RI. Also, evidence exists for the presence of petroleum
solvents near the northwest and west trenches. Sampling and
analysis for total petroleum hydrocarbons (TPH) would be
performed during the remedial design to ensure that soil and
ground water treatment systems are capable to effectively
treat the additional contamination. Long-term environmental
monitoring would include positive identification of the
major TICs and sampling and analysis for these compounds and
TPH. . .
Since several of the PCB analyses in sediment and surface
water were invalidated during the RI, additional s~mpling of
PCBs in sediment and surface water would be performed prior
to or during the design to verify the presence of PCBs and a
risk assessment may need to be performed. If PCBs do pose a
concern, the remedy may need to be modified to address this
contamination.
The goal of this remedial action is to restore the ground
water and surface water to their beneficial uses, which is,
at this Site, a potential future drinking water source.

investigation, and the analysis of all remedial.
alternatives, EPA believes that the selected remedy may be
able to achieve this goal. Although not detected during the
RI, DNAPLs may be present at the Site. Studies to further
investigate the possibility of DNAPLs presence may need to

construction and operation of the remedy.
The ability to achieve cleanup levels at all points
throughout the area of attainment, or plume, cannot be
determined until after implementation of the source control
remedy and until after the ground water extraction and
treatment system has been implemented and operated for a
reasonably significant period of time, modified as
necessary, and contaminated ground water plume response is
monitored over time.
Based on current data, EPA estimates that the ground water
will be extracted and treated for approximately 20 years. .
During operation, the soil treatment and ground water
extraction and treatment systems' performance will be
carefully monitored on a regular basis and adjusted as
warranted by the performance data collected during
operation. These adjustments or modifications may include
any or all of the following: enhancements to the SVE system;
relocation or addition of extraction wells; modification of
withdrawal and pumping rates; alternating pumping rates; and
switching from continuous pumping to pulsed pumping.
If, following a reasonable period of the ground water system
operation, EPA determines that the selected remedy cannot
meet cleanup levels, EPA may consider contingency measures
as a modification to the selected remedy. Such contingency
measures may include the following:
a) engineering controls such as physical barriers, or
long-term gradient control provided by low level
pumping, as containment measures;
b) ARARs may be waived for the cl~anup of the relevant
portions of the aquifer based on the .technical
impracticability of a~hieving further contaminant
reductions and revised cleanup levels may be
established for the relevant portion of the

"to further reduce the mass of the contaminants and
to ensure that the remedy remains protective of
human health and the environment.
The decision to invoke any or all of these measures may be
made by EPA during a future review, following a reasonably
significant period of operation of the selected remedy. If
EPA determines that such contingency measures are necessary,
and are significant or fundamental modifications to the
remedy, such changes will be documented in a future decision
document. "
To the extent required by law, EPA will review the Site at
least once every five years after "the initiation of remedial
action at the Site if any hazardous substances, pollutants
or contaminants remain at the Site to assure that the
remedial action continues to protect human health and the
environment. EPA will also review the Site before the Site
is proposed for deletion from the NPL.
XI.
STATUTORY DETERMINATIONS
The remedial action selected for implementation at the Picillo
Farm Superfund Site is consistent with CERCLA and the NCP. The
selected remedy is protective of human health and the
environment, attains ARARs and is cost effective. The selected
remedy also satisfies the statutory preference for treatment
which permanently and significantly reduces the mobility,
toxicity or volume of hazardous substances as a principal
element. Additionally, the selected remedy utilizes alternate
treatment technologies or resource recovery technologies to the
maximum extent practicable. "
A.
The Selected Remedy is Protective of Human Health and
the Environment
The remedy at this Site will permanently reduce the risks
posed to human health and the environment by eliminating,
reducing or controlling exposures to human and environmental
receptors through treatment, engineering controls, and
institutional controls. Specifically, the risk presented at "
the Site to human health is the potential ingestion of the
contaminated ground water. The potential use of surface
water as drinking water also poses a risk to human health.
The selected remedy uses a soil treatment system which will
remove the contamination from the soil and reduce the
leaching of the contamination from the soil into the ground
wa~er~ The potential for direct contact of the

-------
RECORD OF DECISION SUMMARY
Picillo Farm site
Page 66
soil will be eliminated through the off-site removal of the
PCB-contaminated soil to an EPA-approved disposal facility.
The management of migration portion of the selected remedy,
in combination with the source control, will return the
ground water and surface waters to their beneficial use in
approximately 20 years. A long-term monitoring program will
ensure that the remedy remains protective of human health
and the environment.
Moreover, the selected remedy will achieve potential human
health risk levels that attain the 10-4 to 10-6 incremental
cancer risk range and a level protective of noncarcinogenic
endpoints, and will comply with ARARs and the "To Be
Considered" criteria. At the ti~e that the Interim Ground
Water Cleanup Levels identified in the ROD and newly
promulgated ARARs and modified ARARs which call into
question the protectiveness of the remedy have been achieved
and have not been exceeded for a period of three consecutive
years, a risk assessment shall be performed on the residual
ground water contamination to determine whether the remed.ial
actio~ is protective. This risk assessment of the residual
ground water contamination shall follow EPA procedures and
will assess the cumulative carcinogenic and non-carcinogenic
risks posed by exposure to ground water (e.g., ingestion of
ground water from domestic water usage).
If, after review of the risk assessment, the remedial action
is not determined to be protective by EPA, the remedial
action shall continue until protective levels are achieved
and have not been exceeded for a period of three consecutive
years, or until the remedy is otherwise. deemed protective.
These protective residual levels shall constitute the final
cleanup levels for this Record of Decision and shall be
considered performance standards for any remedial action.

Considering all of the elements of the selected remedy, EPA
has determined that the selected remedy is protective of
human health and the environment.
B.
The Selected Remedy Attains ARARs
This remedy will attain all applicable or relevant and
appropriate federal and state requirements that apply to the
Site. Environmental laws from which ARARs for the selected.
remedial action are derived, .and the specific ARARs include:

All listed ARARs can be found in Tables 8, 9, and 10 in Appendix
B of this Record of Decision. These tables provide a brief
synopsis of the ARARs and an explanation of the actions necessary
to meet the ARARs. These tables also indicate whether the ARARs
are applicable or relevant and appropriate to actions at the
site. In addition to ARARs, the tables describe standards that
are To-Be-Considered (TBC) with respect to remedial actions. The
more significant ARARs are also discussed below.
i.
Chemical Specific
Federal and State Drinkinq Water Standards
The ground water aquifer under the Site is classified as
Class lIB under. the Federal Ground Water Protection strategy'
and Class GA-NA by the State of Rhode Island, which is a
source of potable water. While Maximum contaminant Levels
(MCLs) and Maximum Contaminant Level Goals (MCLGs)
promulgated under the Federal Safe Drinking Water. Act are
not applicable to ground water, they are relevant and
appropriate to ground water cleanup or to the attainment of
ground water cleanup levels because the ground water may be
used as a drinking water source in the reasonably

-------
RECORD OF DECISION SUMMARY
Picillo Farm Site
Page 70
usable ground water be restored to their beneficial uses
whenever practicable. See 40 CFR ~ JOO.4JO(a) (iii) (F).
The ground water quality standards established in the Rhode
Island Rules and Regulations for Ground Water Quality are
relevant and appropriate when the established values are
more stringent than federal MCLs and non-zero MCLGs.
The remedy will attain these ARARs as well as those
identified in Appendix a, TableS, and will comply with
those regulations which have been identified as TBCs by
meeting the ground water cleanup levels throughout the
contaminated plume in approximately 20 years as a result of
the implementation of the selected source control and
management ~f migration remedy. Removal of contaminants
from the soil and operation of the ground water extraction
and treatment system will reduce levels of the contamination
'at the Site to the interim cleanup levels identified in this
ROD. .
Federal and State Surface Water Standards
Under the Clean Water Act (CWA) , EPA has established water
quality criteria found in 40 CFR 131 Subpart 0, which are
nonenforceable guidelines to be used by states to establish
water quality standards. These water quality criteria are
considered relevant and appropriate requirements for cleanup
of the surface water at the Site.
The Rhode Island Water Quality Standards established under
the Rhode Island Water Quality Regulations for Water
Pollution Control, which define the water quality standards
of a water body by designating the use or uses to be made of
the water body and by setting criteria necessary to protect
those uses, are applicable requirements. The Rhode Island
Water Quality Regulations for Water Pollution Control, which
also regulate the restoration, preservation, enhancement and
protection of state waters, are applicable requirements for
any surface water discharges at the Site.
ii.
. Location Specific
Areas immediately adjacent to the west and south of the
Picillo Farm property are designated wetlands under the
Rhode Island Department of Environmental Management Rules
and Regulations governing the enforcement of the FreshWater
Wetlands Act. Portions of the Site lie within these
wetlands under jurisdiction of the Rhode Island Fresh Water
Wetlands Act. Activities associated with the selected

-------

Page 71
the applicable requirements of the Rhode Island Fresh Water
Wetlands Act and will be met.
iii.
Action Specific
Federal and State air standards and regulations will guide
remediation measures designed to limit contaminant emissions
from the soil and ground water treatment systems. Under the
Clean Air Act (CAA), requirements setting emission' standards
for benzene and vinyl chloride are relevant and appropriate
for any air emissions caused by the soil and ground water
treatment systems. Certain provisions of the Resource
Conservation and Recovery Act (RCRA) are also relevant and
appropriate for air emissions from the soil and ground water
treatment systems. Certain provisions of the Rhode Island
Air Pollution Control Regulations, which set emission
. limitations are applicable and will be met during excavation
of PCB-contaminated surface soil and for air emissions from
soil and ground water treatment systems at the Site.
Under the Clean Water Act (CWA), substantive permit
requirements of the National Pollution Discharge Elimination
System (NPDES) for point source discharges are applicable if
treated water is discharged into the surface waters. As
discussed above under Chemical Specific ARARs, the Rhode
Island Water Quality Standards are applicable requirements
and will be met through treatment and proper controls for
any surface water discharges at the site. If treated ground
water will be reinjected into the aquifer, Rhode Island
Underground Injection Control (UIC) and Rhode Island Rules
and Regulations for Ground Water Quality will be applicable
requirements. The reinjection system will be designed,
constructed and operated in accordance with these
regulations to prevent ground water contamination.
Storage and disposal of PCB-contaminated soil will comply
with storage, treatment and disposal requirements of the
Toxic Substance Control Act (TSCA) through proper
engineering design and controls. These regulations are
currently determined to be relevant and appropriate.
However, if PCB concentration during the remedial design and'
action are determined to exceed 50 ppm, these regulations
become applicable. The disposal of PCB-contaminated soils
will provide a permanent and protective' remedy that. would
satisfy the re~uirements.of TSCA.
C.
The Selected Remedial Action is Cost-Effective
In the Agency's judgment, the selected. remedy is cost

proportional to its costs. In selecting this remedy, once
EPA identified alternatives that are protective of human
health and the environment and that attain, or, as
appropriate, waive ARARs, EPA evaluated the overall
effectiveness of each alternative by assessing the relevant
three criteria -- long term effectiveness and permanence;
reduction in toxicity, mobility, and volume through
treatment; and short term effectiveness, in combination.
The relationship of the overall effectiveness of this.
remedial alternative was determined to be proportional to
its costs. The costs of this remedial alternative are:

Costs based on UV/oxidation option; costs for the

VIII, Description of Alternatives)
With respect to the source control alternatives, the
selected alternative, SC-2 is protective of human health and
the environment. Additionally, SC-2, in comparison with the
other source control alternatives, is the least expensive
alternative with the greatest proportional over-all
effectiveness. Alternatives SC-3 (excavation and thermal
desorption) and SC-4 (off-site incineration) do not provide
overall effectiveness and protectiveness proportional to
their respective costs. Alternative SC-4 is the most
expensive source control alternative with an estimated total
cost of $101,200,000. Alternative SC-3 is the next most
expensive with a cost of $23,900,000 which is almost six
times higher than the cost of SC-2, the selected source
control remedy.
Moreover, alternatives SC-3 and SC-4 would each present a
much greater short-term risk than the selected alternative
because of the required excavation of a large volume of
soil. Although the in-situ treatment components of
alternatives SC-3 and SC-4 create an initial reduction in
contaminant concentrations, these alternatives are not
considered cost-effective due to the 'low short-t.erm
effectiveness, the high implementation ~osts, and the
adverse impacts from extensive soil excavation. Thus, of
the three source control alternatives evaluated and
considered protective, the selected source control remedy,

-------

Paqe 73
In conjunction with the implementation of the selected
source control remedy, two of the management of migration
alternatives, alternative MM-2 and selected alternative MM-
3, would attain ARARs and be protective of human health and
the environment. Alternative MM-2 would cost $14,200,000 to
implement. The selected alternative, MM-3, would cost
approximately 20% less than MM-2 at a cost of $11,600,000.
Both, MM-2 and MM-3 would achieve restoration in the source
and concentrated regions of the plume in approximately 20
years. Alternative MM-2 differs in that it entails active"
treatment of the dilute region of the plume.
Through active treatment, alternative MM-2 would attain
cleanup levels in the dilute portion of the plume in
approximately 8 years. However, restoration would not be
complete until cleanup levels are attained in the source and
concentrated regions of the plume. The selected management
of migration remedy, MM-3, provides for the natural
attenuation of the dilute portion of the plume which would"
meet cleanup levels in the same approximately 20 years
period that it would take to attain cleanup levels in the
source and concentrated regions. This would be achieved
through isolation and active treatment of the source and
concentrated regions of the plume.
Although the active treatment of the dilute portion of the
plume in alternative MM-2 achieves restoration of the dilute
region in a shorter period of time than MM-3, MM-2 presents
a greater short-term risk of impacting the environment. The
active treatment of the dilute region would require the
extraction of a larger amount of ground water." The active
extraction of ground water from the dilute portion of the
plume would be implemented in very close proximity to the
Unnamed Swamp and thus, increase the possibility of
adversely impacting wetland areas. In selecting the.
management of migration remedy, EPA weighted the twelve-year
estimated time difference in the restoration of the dilute
region of the plume and the time period "for overall
restoration of the aquifer and surface water against the
cost and the short-term effectiveness of MM-2 and MM-3.
Based on these considerations, EPA has determined that the
selected management of migration remedy, MM-3, provides a
greater overall effectiveness and protectiveness
proportional to its costs than does alternative MM-2.

treatment technologies or resource recovery technologies to
the maximum extent practicable. This determination was made
by deciding which one of the identified alternatives
provides the best balance of trade-offs among alternatives
in terms of: 1) long-term effectiveness and permanence; 2)
reduction of toxicity, mobility or volume through treatment;
3) short-term effectiveness; 4) implementabilitYi and 5)
cost. The balancing test emphasized long-term effectiveness
and permanence and the reduction of toxicity, mobility and
volume th~ough treatment; and considered the preference f6r
treatment as a principal element, .the bias against off-site
land disposal of untreated waste, and community and state
acceptance. The selected remedy provides the best balance of
trade-offs among the alternatives.
Except for the No-Action Alternative SC-1, all of the source
control alternatives (SC-2, SC-3 and SC-4) would provide
overall protection of human health and the environment and
meet their corresponding ARARs. All three alternatives
would offer good protection against the principal risks
associated with potential ingestion of contaminated ground
water in the foreseeable future resulting from the leaching
of contaminants from the soils into the ground water.
Although alternative SC-4 would offer the most permanent
protection on-site because all contaminated soils would be
transported and disposed of off-site, it would pose
potential short-term risks related to major on-site
excavation and the transport of waste off-site.
Implementation of this alternative would also be unreliable
as a result of the following major considerations: The
ability of the local roads to handle the large volume of
traffic associated with the off-site transport of waste, and
the uncertainty in securing an incineration facility which
could handle the large volume of contaminated soils
(approximately 94,000 cubic yards). In addition, the
$101,200,000 cost to implement SC-4 would be the most
expensive of all the alternatives.
Alternative SC-3 would also be very effective in reducing or
eliminating long-term risks associated with exposure to soil
leachate. However, even after an initial in-situ treatm~nt,
the sho:::--. "::erm risks to nearby communities and workers
associat8~ with extensive excavation of contaminated soils
create major uncertainties with implementing SC-3.
Alternative SC-3 would also be the next most expensive

Page 7S
In EPAi~ analysis, the selected remedy SC-2 would provide
better overall protection through long-term effectiveness
and permanence, and cost effectiveness than the other.
alternatives. At a cost of $4,100,000, SC-2 would be
designed to treat the contaminants in the subsurface soils
without the need for excavation, thereby avoiding the short-
term risks associated with the other alternatives. To
maximize the long-term effectiveness of SC-2, a pilot study
would be performed during the design phase to optimize the
operating parameters and minimize uncertainties in the
implementation. . .
Two of the management of migration alternatives, MM-2 and
MM~3, in conjunction with the implementation of any active
SC alternative, would provide overall protection of human
health and the environment and would attain all ARARs. Both
alternatives utilize the same permanent solution, extraction
and treatment of ground water, to reduce the contamination
in the aquifer and surface water. Both alternatives would
be equally implementable since they both employ similar
technology. In addition, both alternatives MM-2 and MM-3
would provide essentially the same long-term effectiveness.
However, the cost of implementing MM-3, $11,600,000, is less
than the $14,200,000 cost to implement MM-2.
The difference between the alternatives would be the amount
of contamination that is extracted and treated versus the
amount of contamination that is allowed to naturally
attenuate. Alternative MM-2 would provide greater reduction
in toxicity, mobility or volume through treatment by
extracting and treating water in the entire plume, while the
selected remedy MM-3 would only extract and treat ground
water in the source and concentrated portions of the plume,
allowing the dilute region to naturally attenuate.. By
containing and treating contamination in the' source and
concentrated regions, ground water in the dilute region is
expected to be remediated in approximately 20 years in the
selected remedy, compared to the' approximate 8 year period
to treat the dilute region under alternative MM-2. However,
the importance of this distinction is lessened because the
entire restoration time for the source and concentrated
regions of the plume would be 20 years for both MM-2 and MM-
3. ' '
Although the, restoration time of 20 years for the entire
plume is similar for both alternatives, alternative MM-2 is
expected to have a greater short-term impact on the
environment. The extraction arid treatment of the dilute
portion of the plume under MM-2 would create a greater risk

Page 76
largeramc~nt of ground water in the immediate proximity to
the wetlands would be extracted. Based on the above
considerations, EPA has determined that the selected remedy
MM-3 provides a greater overall effectiveness and
protectiveness than MM-2.
E.
The Selected Remedy satisfies the Preference for
Treatment Which Permanently and significantly Reduces
the Toxicity, Mobility or Volume of the Hazardous
Substances as a Principal Element.
The principal elements of the selected remedy are in-situ
treatment of soil by enhanced vapor extraction and
extraction and treatment of ground water. These elements
address the primary threat at the Site, which is the
contamination of soil, ground water and surface water. The
selected remedy satisfies the statutory preference for
treatment as a principal element by: permanently reducing
the volume of contaminants; reducing leaching of
contaminants from the soil into the ground water; and
reducing the amount of contaminants migrating into the
dilute portion of the ground water plume and the surface
water. .
XII. DOCUMENTATION OF NO SIGNIFICANT CHANGES
EPA presented a proposed plan (preferred alternative) for
remediation of the Site on June 29, 1993. The source control
portion of the preferred alternative included treatment of soils
contaminated with VOCs and SVOCs by in-situ thermally enhanced
soil vapor extraction and excavation and removal off-site of
surface soil contaminated with PCBs. The management of migration
portion of the preferred alternative included extraction and
treatment of contaminated water to federal and state drinking
water standards by.UV/Oxidation and carbon adsorption or air
stripping and carbon adsorption. No significant changes from the
Proposed Plan have been made to the selected remedy as detailed
in the Record of Decision.
XIII. STATE ROLE
The Rhode Island Department of Environmental Management has
reviewed the various alternatives and has indicated. its support
for the selected remedy. The State has also reviewed the .
Remedial Investigation, Risk Assessment and Feasibility Study to
determine if the selected remedy is in compliance with applicable
or relevant and appropriate State Environmental laws and
~egulations. The State of Rhode Island concurs with the selected
~emedy for the Picillo Farm Superfund Site. A copy of the

    RE:
    Record of Decision for the Picillo Farm Superfund Site, Coventry, Rhode Island
    Dear Mr. Keough:
    This is to advise you that the State of Rhode Island concurs witn the selected remedy
    detailed in the September 1993 Record of Decision for the Remedial ACtion of the Picillo
    Farm Superfund site. This concurrence is based upon all aspects of the abovementioned
    Record of Decision being adequately addressed and implemented during design,
    construction and operation of the remedy.
    I The Depanment wishes to specifically emphasize the following aspects of the Record of
    i Decision:

    The remedy as proposed and implemented must ensure compliance with all
    applicable or relevant and appropriate State and FederaI statues, regulations and
    policies.
    
    Contaminant specific interim cleanup goals, as stated in this Record of Decision. are
    an acceptable short term strategy. However, the long term remedial objective is to
    restore the site to acceptable levels that satisfy the remedial risk goals for an
    anticipated future use as a possible residential area.
    This remedy must identify institutional controls that are applicable throughout the
    remedial action project life, which are protective of human health. Also, in the event
    that the remedial risk goals cannot be achieved, long-term controls (applicable after
    the remedy is terminated) must be instituted to prevent an unacceptable risk to
    human health and the environment.

    The Record of Decision states that extracted groundwater will be. treated by
    ultraviolet (L'V)joxidation and carbon adsorption Q!: air stripping and carbon
    adsorption. . Based upon itS long-term effeCtiveness and on-site destruction
    capabilities of contaminantS, the State prefers the implementation of (Uv")joxidation
    over air stripping. Air stripping transfers contamination to another media rather than
    offering destruction ability.
    Finally, I urge EPA to make every effort to assure that the remedy will be implemented in
    a timely and. efficiem manner.
    Thank you for providing us with an opportunity to review and concur with this important
    Record of Decision. . .
