16. Abstract (Umtt: 200 words)
The 2.7-acre Tronic Plating site is an electroplating and metal anodizing facility
located in Babylon, Suffolk County, New York. Land use in the area is predominantly
light industrial. The site is bounded by light industrial businesses to the north,
west, and northeast, and the Pinelawn Cemetery to the south and southeast. Three
aquifers beneath the site, the unconfined Upper Glacial aquifer, the semi-confined
Magothy aquifer, and the confined Lloyd Sand aquifer, supply public and private needs
to the entire population of Suffolk County. The Upper Glacial and the Magothy aquifers
are of environmental concern because studies have shown that they may be
hydrogeologically connected to the site. From 1968 to 1984, onsite wastewater disposal
for the electroplating and metal anodizing facility was serviced by four industrial
leaching pools, one sanitary leaching pool, and one drywell. Between 1972 and 1982,
the County collected and analyzed industrial discharges, onsite leaching pools, and an
onsite storm drain and found elevated levels of metals. In 1983, Tronic Plating
arranged to pump out, clean, and backfill the industrial leaching pools, and the site
was connected to the municipal sewer system. In 1993, EPA required the PRP to remove
approximately 230 yd^ of contaminated sediment and soil from each of the three onsite
storm drains, the three adjoining overflow drains, and the sanitary leaching pool and

a first and final remedy for the onsite soil, sediment, and ground water. Results of the
RI and prior removals performed by EPA were adequate to protect human health and the
environment; therefore, there are no contaminants of concern affecting this site..
The selected remedial action for this site is no further action. Prior EPA removals were
sufficient to address the risks posed to human health and the environment. There are no

STATEMENT OF BASIS AND PURPOSE
This decision document presents the selected remedial action for the Tronic Plating Site
(Site) located in the Town of Babylon, Suffolk County, New York which was chosen in
accordance with the requirements of the Comprehensive Environmental Response,
Compensation, and liability Act of 1980 (CERCLA) as amended by the Superfund
Amendments and Reauthorization Act of 1986 (SARA), and the National Oil and
Hazardous Substances Pollution Contingency Plan (NCP). This decision document
summarizes the factual and legal basis for selecting the remedy for the Site.
The New York State Department of Environmental Conservation (NYSDEC) concurs with
the selected remedy. A letter of concurrence from NYSDEC is attached to this document
(Appendix IV).
The information supporting this remedial action decision is contained in the administrative
record for the Site, an index of which is appended to this document (Appendix HI).
DESCRIPTION OF THE SELECi'HD REMEDY: NO FURTHER ACTION
The United States Environmental Protection Agency (EPA), in consultation with the State
of New York has determined that the Site does not pose a significant threat to human
health and the environment and, therefore, remediation is not necessary nor appropriate.
This determination is based on the results of the Phase I and Phase n remedial
investigations conducted at the Site from 1989 to 1992, the risk assessment performed for
the Site and the sediment and soil removal activities performed pursuant to an
Administrative Order on Consent that were completed on August 13,1993. The Phase I
and Phase n studies showed that, with the exception of a localized plume of cadmium, the
groundwater contamination beneath the Site cannot be attributed to the past disposal
practices at the Site. Also, neither the groundwater nor the soils at the Site pose an
unacceptable risk to human health and the environment and are within EPA's acceptable
risk range. Finally, the removal activities have resulted in the removal of cadmium and
other metals from the contaminated on-site storm drains, sanitary inching pool and drywell,
thereby addressing the localized phone of cadmium in ground water. Therefore, "No
Further Action" is the selected remedy for the She.

DECLARATION OF STATUTORY DETERMINATIONS
In accordance with the requirements of CERCLA, as amended, and the NCP, EPA, in
consultation with the State of New York has determined that the Tronic Plating Site does
not pose a significant threat to human health or the environment, therefore, no further
remedial action is necessary. A five (5) year review is not required for the Tronic Plating
Site because no hazardous substances remain at the Site above health-based levels. EPA
has determined that its response at this site is complete. Therefore, the Site now qualifies
for inclusion on the Construction Completion List

SITE NAME, LOCATION AND DESCRIPTION
The Tronic Plating Company Site (Site) is located at 168 Central Avenue in Fanningdale,
Town of Babylon, Suffolk County, Long Island, New York. The Site occupies the southeast
portion of a building owned by Commerce Holding Company, Inc. situated on Commerce
Drive and the surrounding property, an area of approximately 7,200 square feet within a
117,000 square-foot lot (See Figure 1.) This Site is a rectangular, flat, commercially
developed property. With the exception of a 50 by 75 foot landscaped front lawn, the area
surrounding the building at the Site is paved for parking and shipping access. The southern
boundary of the Site is the southern edge of the front lawn adjacent to Central Avenue.
The Site surroundings consist of light industrial businesses to the north, west, and northeast.
The Pinelawn Cemetery is located to the south and southeast. A wooded area owned by
the Pinelawn Cemetery and separated from the Site by Central Avenue and an industrial
lot, is located approximately 500 feet to the south. The area north of the Site, lower
Melville, has no municipal sewer service and virtually all industries discharge their
wastewater to ground-water infiltration systems, thereby impacting the ground-water quality
in the area.
The relatively level surface of the Site slopes gently to the south-southeast at a grade of
approximately 3 percent Except for the lawn, the Site surface is primarily impermeable
given the presence of the building and paved areas. Surface water from precipitation drains
from the building and the paved areas into a system of 12 storm drains located along the
parking area (Commerce Drive).
There are 3 major aquifers underlying the Site. These are: the unconfined Upper Glacial
aquifer; the semi-confined Magothy aquifer; and, the confined Lloyd Sand aquifer. The
total thickness of these three aquifers beneath the Site is approximately 1,200 feet. The two
aquifers of environmental concern for this Site are the Upper Glacial and the Magothy,
since the Lloyd Sand is a deep aquifer (1000 feet) and not hydrogeologically connected to
the above aquifers. Studies have indicated that the Upper Glacial and Magothy aquifers
may be hydrogeologically connected under the Site. The Magothy aquifer is totally
dependent upon downward percolating rainfall and recharge from the overlying Upper
Glacial deposits for its surface replenishment
The Raritan Formation of Late Cretaceous age is the deepest geologic formation of
unconsolidated deposits beneath the Site. It rests directly on the crystalline bedrock and is
overlain by the Magothy Formation. The Raritan Formation occurs beneath the entire area
of Long Island but does not outcrop near the Site or within Suffolk County. Formation
thickness ranges from 300 to 600 feet The Raritan Formation is divided into a lower unit,
the Lloyd Sand aquifer, and the upper unit, the Raritan day. The Raritan Clay functions
as an aquiclude, separating the ground water within the Lloyd Sand from the ground water
within the overlying Magothy Formation. Beneath the Site, the Lloyd Sand is approximately
-1-
-------
200 to 300 feet thick and the relatively impermeable Raritan day is approximately 175 feet
thick.
The Magothy Formation is a thick sequence of Late Cretaceous age sediments which were
deposited upon the underlying Raritan Formation. At the Site the Magothy Formation is
approximately 700 feet thick. The Magothy is overlain directly by the more recent
Pleistocene deposits which comprise the Upper Glacial aquifer. Permeable outwash deposits
comprise the bulk of the Upper Glacial deposits. These sediments rest unconformably upon
the Magothy Formation at an elevation equivalent to mean sea level, or 100 feet below
grade at the Site location. The Upper Glacial deposits are approximately 100 feet thick
directly under the Site. The Upper Glacial sediments consist of horizontally stratified beds
of fine to coarse sands and gravel. The Magothy and the Upper Glacial aquifers have
historically been distinguished by differences in sediment color, texture and composition.
The direction and relatively rapid rate of shallow (near the water table) ground-water flow
beneath the Site is southerly at approximately 2 feet per day. This information was
developed from a series of water level measurements collected from piezometers installed
on-site and agrees with literature describing the hydrologic conditions for the area. The
water table at the Site was found to be between 28 to 35 feet below the surface.
Ground water supplies the public and private needs of the entire population of Suffolk
County. The two most commonly tapped aquifers for water supply purposes are the Upper
Glacial and the Magothy. The Magothy aquifer is the primary source of potable drinking
water in the area of the Site. Two water companies purvey water pumped from municipal
wells to the homes and businesses in the vicinity of the Site. The East Farmingdale Water
District supplies the businesses at the Site as well as areas to the south. The Suffolk County
Water Authority also supplies some areas to the south of the Site. Each municipal supply
well generally supplies one million gallons or more per day when in full-scale operation.
All of the local public supply wells are advanced to and completed within the Magothy
aquifer. The nearest municipal well field is located partially downgraient at 0.9 miles
southwest of the Site. The ground-water flow is to the south. Another municipal supply
well is located 2.4 miles south (downgradient) of the Site and a third municipal well field
is located partially downgradient at 2.8 miles south-southeast of the Site.
Private wells exist in the Site vicinity; these are completed within either the upper Magothy
or the Upper Glacial aquifer. Some are used to supply drinking water to businesses, but
most are used for irrigation or for process and cooling water. The nearest private well used
for drinking water supply services an office at the St. Charles Cemetery and is located
partially downgradient at 0.9 miles south-southwest of the Site. Wells located downgradient
closer to the Site are solely used for irrigation.

SITE HISTORY AND ENFORCEMENT ACTIVITIES
The Tronic Plating Company, Inc. operated an electroplating and metal anodizing facility
at the Site from July 1968 to March 1984. The facility was serviced by 4 industrial leaching
pools, 1 sanitary leaching pool and 1 drywell. The 4 industrial pools are located below the
front lawn of the building, and the sanitary pool is located under the driveway adjacent to
the front lawn. The dry well (a former sanitary leaching pool that was disconnected from
the building) is located in the rear of the former Tronic facility. There are 3 on-site storm
drains, with 2 overflow drains, located in the driveway adjacent to the building and the front
lawn. (See Figure 2.)
The Suffolk County Department of Health Services (SCDHS) records indicate that in
November 1983, the Tronic Plating Company arranged to pump out, dean, and backfill the
industrial leaching pools. There was no indication that the Tronic Plating Company
removed the contents of the storm drains, sanitary leaching pool, or drywell. Also, during
1983 the building on the Site was connected to the Suffolk County municipal sewer system.
In March and April of 1984, the Tronic Plating Company ceased operating at the Site and
moved its facility to Nassau County.
Approximately 125 million gallons of waste water were produced by the Tronic Plating
Company each year. The sources of these wastes were rinse waters from the electroplating,
anodizing and etching processes. Between 1972 and 1982, the SCDHS collected and
performed chemical analyses of fluid samples collected from the Tronic Plating Company's
industrial discharges, as well as from the on-site leaching pools and an on-site storm drain.
The analyses indicated the presence of metals (cadmium, chromium, copper, cyanide, iron,
lead, nickel, silver, zinc) with concentrations characteristic of waste streams generated by
a typical electroplating facility.
Administrative Orders were issued to the Tronic Plating Company by both the SCDHS and
the New York State Department of Environmental Conservation (NYSDEC) regarding its
unpermitted releases of industrial waste. In 1984, NYSDEC conducted a Preliminary
Inspection of the Tronic Plating Company facility. The Site was placed on EPA's National
Priorities List for Superfund cleanup on June 10, 1986.
In July 1987, EPA began preparation of a Work Plan for the performance of a Remedial
Investigation (RI) and Feasibility Study (FS) for the Tronic Plating Site. In May 1988,
Commerce Holding Company, Inc., the owner of the Site property and therefore a
potentially responsible party (PRP), entered into an Administrative Order on Consent
(AOC) with EPA to conduct the RI/FS. The RI was performed in two phases, each
designed to characterize the extent of ground-water and soil contamination associated with
the waste releases at the Site.
The Phase I study was performed in the Spring of 1989 and the draft RI report completed
in May 1990. Upon review of the Phase I report, EPA required that supplemental work,
-3-
-------
or a Phase n study, be conducted. The Phase n investigation was completed in 1991, and
the final RI report was prepared in March 1992. Using the information presented in the
final RI report, EPA conducted a baseline risk assessment to determine whether
contaminants identified at the Site pose a current or potential future risk to public health
and the environment. The results of this assessment are presented in the final risk
assessment report dated December 31, 1992.
On May 7, 1993, Commerce Holding Company, Inc. entered into another AOC with EPA
to remove contaminated sediment and soil from each of the three on-site storm drains, SD-1
(Main), SD-2 (Main) and SD-3 (Main), and the three adjoining overflow drains SD-1
(Overflow), SD-2 (Overflow) and SD-3 (Overflow) to the depth of 5 feet below the bottom
of each concrete underground structure. Soil samples were collected from the bottom of
the excavation and analyzed to determine the levels of cadmium, lead and chromium pres-
ent According to the AOC, the removal will be considered effective, based on EPA and
NYSDEC cleanup goals developed for the Site, if the levels of these contaminants meet the
following cleanup goals: cadmium -10 parts per million (ppm); lead - 200 ppm; chromium -
98 ppm. The AOC also included the provision that Commerce Holding Company, Inc.
would clean out any contaminated sediments and soil to the depth of 5 feet in the sanitary
leaching pool and drywell, where no direct soil borings were advanced in the RI. Finally,
Commerce Holding Company, Inc. agreed to take samples of the remaining soils at each
location where sediment/soil removal would take place and analyze this soil to confirm that
contaminant concentrations and, therefore, the reservoir of the contaminants in the Site soils
were significantly reduced. The field work required pursuant to the AOC has been
completed.
HIGHLIGHTS OF COMMUNITY PARTICIPATION
There was limited community involvement at the Site, possibly because it is in an industrial
area and there are no residences nearby. No one attended the public meeting held during
the public comment period except two local officials. No comments were submitted during
the public comment period.
SCOPE AND ROLE OF RESPONSE ACTION
This is the first and only operable unit for the Site. The primary objective of this operable
unit is to determine the nature and extent of contamination at the Site and to take
measures, as appropriate, to ensure protection of human health and the environment EPA
has determined that no further action is necessary because there is no risk to public health
and the environment
However, previous actions, namely the removal action, have occurred. The removal work
required by the Order was carried out by Commerce Holding Company, Inc. under the
-------
supervision of EPA. Field work began on July 22,1993 and was satisfactorily completed on
August 13,1993. (See Figure 3 for a typical leaching pool and storm drain design.) Storm
water was removed from the on-site storm drains SD-1 (Main) to SD-3 (Main) with a
vacuum truck. Samples of storm water and bottom sediments were taken in order to
characterize these wastes for disposal subsequent to their removal. Once the storm water
was emptied, a vacuum truck ("super-sucker") was used to remove contaminated sediments
and soils. An X-ray fluorescence field-screening device was employed to determine the
depth of the excavation. (See Table H for XRF results.) Confirmatory soil samples were
taken at the bottom of each excavation and sent for laboratory analysis to ensure that the
cleanup goals developed by EPA and NYSDEC were met.
Drywell DW-1 was sampled to determine if excavation was necessary, since DW-1 was not
adequately characterized during the RI. Results of the analysis of the samples revealed the
presence of cadmium at 19.1 ppm, chromium at 22.9 ppm and lead at 16.6 ppm. EPA
directed Commerce Holding Company, Inc. to excavate Drywell DW-1.
The sanitary leaching pool SP-1 (Main) was the only excavation not to pass the field
screening, which indicated that the cleanup goals had not been met. Concrete rings in SP-1
(Main) about 4.5 feet deep were caked with a green-blue sludge which field screening
indicated contained 17,000 ppm of chromium. Therefore, further field work was necessary.
SP-1 (Main) required excavation deeper than that which could be supported using the super-
sucker because the hole would collapse. A larger hole was excavated using a back hoe and
sediment and soil were removed to a depth of 30 feet, and a confirmatory sample was taken
at the bottom of the excavation. The existing concrete rings were replaced and new ones
were installed. In addition, an overflow was found for SP-1 (Main), located roughly between
SD-1 (Main) and SD-1 (Overflow).
In total, 230 cubic yards of contaminated soil were removed from the Site and shipped to
hazardous waste landfills. Approximately 10 cubic yards of cyanide-tainted wastes were
disposed of at L.W.D., Inc. in Calvert City, Kentucky, and the remaining wastes were
shipped to Michigan/Wayne Disposal, Inc. in Belleville, Michigan. The storm water was
disposed of at the Suffolk County Department of Public Works plant at Bergen Point, New
York.
Analytical results from confirmatory samples taken from the bottom of the removal
excavations were within an acceptable range of the EPA and NYSDEC cleanup goals of
cadmium - 10 ppm; lead - 200 ppm; and chromium - 98 ppm. The level of metals in the
bottom of each excavation are reported in Table G.
This action achieved the removal of cadmium from the Site sediment Cadmium in Site
sediments may have acted as a source of contamination to the ground water. Cadmium was
present in the ground water at one sampling location in concentrations exceeding State and
Federal primary drinking water standards or mam'tniim contaminant levels (MCLs).
Therefore, since the potential source of cadmium to the ground water was removed,
-5-
-------
concentrations of cadmium in the ground water at the Site should not increase. This action
also achieved the removal of lead and chromium and any other potential ground-water
contaminants found in the contaminated sediments of the storm drains and associated
overflow drains, the sanitary leaching pool and the drywell.
SUMMARY OF SITE CHARACTERISTICS
Under the supervision of EPA, Commerce Holding Company Inc.'s consultant, CA. Rich
Consultants, performed the RI in two consecutive phases. The Phase IRI included: 1) a
geophysical survey; 2) soil sampling associated with monitoring well installation; 3) ground-
water sampling; 4) sampling of sediments and water from storm drains; 5) permeability
testing; 6) a topographic survey; and, 7) numerical modeling of ground water. The Phase
n RI included: 1) soil and sediment sampling from storm drains; 2) soil sampling adjacent
to storm drains; 3) an installation of additional monitoring wells; 4) sampling of ground
water; and, 5) an additional topographic survey. The samples collected during these studies
were analyzed for organic and metal contaminants on EPA's Target Compound List.
The results of the two phases of the RI indicated that ground water, soils and storm-drain
sediments at the Site were contaminated with volatile organic compounds (VOCs) and
metals. The following summary presents the RI results for site soils and the ground water
directly below and in the vicinity of the Site. However, these data represent conditions at
the Site prior to the removal action that was recently conducted. Levels of contaminants
in the storm drains and associated overflow drains, the sanitary leaching pool and the
drywell are now much lower. Table G in Appendix II contains the post removal sampling
results for soils in the above-mentioned areas.
Contamination of Site Soils
Organic Compounds
The soil samples collected beside and below the former leaching pools did not indicate
significant presence of VOCs. Acetone was detected at random sampling locations, with
concentrations ranging between 26 to 95 parts per billion (ppb). Although it was absent
from the field blanks it was also detected in the background soils obtained from a boring
for the upgradient monitoring well, MW-1D. There was also one occurrence of each
pesticide, 4,4'-DDE and 4,4-DDT, in the leaching pool LP-2 at a depth of 14 to 16 feet
below grade. Several phthalate compounds were detected in soil samples from the four
leaching pools. Several phthalate compounds, however, were also detected in a number of
field blanks collected for the soil samples.
Freon 113 and methylene chloride were detected in the soil samples collected near the
drywell, DW-1. Methylene chloride and acetone were also detected near the former sanitary
leaching pooL
-------
Several VOCs were detected in the bottom sediments from the 3 on-site storm drains. The
concentrations ranged from 13 ppb of methylene chloride to 140 ppb of acetone at storm
drain SD-2 (Main), 2 ppb of tetrachloroethylene (PCE) to 50 ppb of acetone at storm drain
SD-3 (Main) and 20 ppb of vinyl chloride to 180 ppb of trichloroethylene (TCE) at storm
drain SD-S (Main). Polynudear aromatic hydrocarbons, such as pyrene, fluoranthene,
fluorene and naphthalene, were detected in the sediments from the main storm drains SD-2,
SD-3, SD-5, SD-6 and SD-7. The origin of these compounds may be the presence of asphalt
pavement and/or exhaust and drippings from automobile engines. As with the leaching
pools, phthalate compounds were detected in the storm-drain sediments.
The Toxicity Characteristic Leaching Procedure (TCLP) test was performed on storm drain
sediment samples from SD-1 (Main), SD-2 (Main) and SD-3 (Main). This test determines
the amount of specific contaminant which may leach out of the contaminated medium, in
this case sediment, over an extended period of time. Tetrachloroethylene and 2-butanone
were detected in the leachate from the three storm drains at concentrations two to five
orders of magnitude below the regulatory levels, respectively.
In summary, the RI results indicated that the organic contamination of the Site soils did not
appear to be high, widespread or predominant at any one disposal location. Also, with the
exception of acetone, PCE and TCE found in the storm-drain sediments, the organic
contaminants detected in the soils were not associated with ground-water contamination by
these compounds.
Inorganic Compounds
During the RI, increased levels of cadmium, chromium, copper, cyanide, lead and nickel
were found in soil samples collected between the bottom of tile leaching pools and 20 feet
below grade for the four former industrial leaching pools, LP-1* through LP-4. These
increased levels were identified by comparisons of the sample concentrations with
background soil levels measured in the boring for the upgradient ground-water monitoring
well, MW-1D. The following were the background and the maximum concentrations,
respectively, of metals in soils found in the RI leaching pool samples: chromium - 53 ppm
and 153 ppm; copper - 5.9 ppm and 38 ppm; cadmium - not detected and 82 ppm; cyanide
- not detected and 46.9 ppm, lead -1.1 ppm and 6.7 ppm, and nickel - not detected and 13.8
ppm. Soil samples obtained at the 38 to 40 foot depth beneath the leaching pools, at the
water table, indicated conditions generally similar to background.
The analyses of soils obtained from the soil boring adjacent to the sanitary leaching pool,
SP-1 (Main), revealed the presence of both chromium and cadmium at levels above
background. The levels of these metals were elevated in samples from both the 19 to 21
foot and the 37 to 39 foot depths. Chromium was detected in the 44.1 to 62.6 ppm range
and cadmium was detected in the 2 to 3.9 ppm range. The analyses of subsurface soils from
-7-
-------
a boring in the vicinity of the dry well, DW-1, indicated that metal levels were generally
similar to levels reported for background samples.
Metals were detected in the bottom sediments of all 8 storm drains sampled for the RI.
The 3 storm drains located on the Site, SD-1 (Main) through SD-3 (Main), contained
significantly higher levels of cadmium, chromium and lead in comparison with the drains
SIM (Main) through SD-8 (Main). For example in storm drains SD-1 (Main) through SD-3
(Main): cadmium ranged from 73 to 1,130 ppm; chromium ranged from 126 to 1,580 ppm;
and, lead ranged from 780 (R) to 2,290 ppm. Storm drains SD-4 (Main) through SD-8
(Main) contained concentrations of cadmium in the range of 2 to 12.8 ppm, chromium in
the range of 16.7 to 60.8 ppm, and lead in the range of 114 (R) to 874 (R) ppm. The (R)
designation indicates an unreliable laboratory result Soil samples obtained from borings
below and beside the storm drains indicate that these soils are slightly above the background
levels. The maximum concentrations obtained from these locations were: cadmium 6.4 ppm;
chromium 22.7 ppm; and, lead 54 ppm.
TCLP was performed on storm-drain sediment samples from SD-1 (Main), SD-2 (Main) and
SD-3 (Main). This test determines the amount of a contaminant which may leach out of a
contaminated medium, in this case sediment, over an extended period of time. Arsenic,
cadmium and lead were detected in the leachate from the three storm drains at concentra-
tions above their respective MCLs. The maximum concentration of these contaminants and
their MCLs are as follows: arsenic - 83.9 ppb, MCL = 50 ppb; cadmium - 3,340 ppb, MCL
= 5 ppb; and, lead - 9300 ppb, Federal action level = 15 ppb.
In summary, metals in the Site soils which were present in high levels prior to the removal
action are chromium, cadmium and lead. These metals were present in particularly high
concentrations in the storm-drain sediments, SD-1 (Main) through SD-3 (Main). This soil
contamination, considered in conjunction with the ground-water data, indicated that these
disposal locations, if not removed, could have continued to be the source of the local plume
of cadmium in the ground water under the Site. In addition, the data indicated that the
storm drain sediment contamination has not spread significantly either laterally or downward
from its present location.
Contamination of Ground Water
Organic Compounds
Several VOCs were detected during the RI in the ground water sampled from the
monitoring wells. (See Figure 4 for monitoring well locations.) The contaminants which
were detected either above the New York State's ground-water protection criteria and
sanitary code, or above EPA's MCLs were: acetone; 1,1-dichloroethylene (1,1-DCE); 1,1,1-
trichloroethane (TCA); trichloroethylene (TCE); tetrachloroethylene (PCE); and, 1,2-
dichloroethylene (1,2-DCE).
-8-
-------
Acetone and 1,1-DCE were detected very infrequently, in 4 of 24 samples analyzed in the
RI. 1,2-DCE and PCE were detected more frequently, in 11 and 21 samples, respectively,
of 24 samples analyzed. The concentrations of these contaminants were not high, however,
and ranged between 1 and 13 ppb for 1,2-DCE, and 1 and 41 ppb for PCE. Furthermore,
the distribution of these contaminants in the ground water appeared random and did not
identify a source.
1,1,1-TCA was detected in 18 of 24 samples analyzed and the concentrations ranged
between 2 and 42 ppb. The highest of these concentrations was located immediately
beneath and downgradient from the Site, indicating that the Site may have been the source
of this contamination, although in the absence of Site soil contamination by 1,1,1-TCA,
upgradient source(s) may be the cause.
TCE was detected in 23 of 24 samples analyzed and the concentrations ranged between 1
and 490 ppb. The highest levels were detected upgradient from the Site. Also, at each
location the most contaminated samples were found in the deeper wells. This distribution
of TCE in the ground water indicated an upgradient source(s).
Inorganic Compounds
Several metals were detected during the RI in the ground water sampled from the
monitoring wells. The metals which were detected either above the New York State's
ground-water protection criteria and sanitary code, or EPA's-MCLs were: antimony;
beryllium; cadmium; total chromium; lead; nickel; silver; thallium; and, hexavalent
chromium.
Cadmium was detected at a concentration of 93 ppb directly downgradient from the on-site
storm drains, SD-1 (Main) through SD-3 (Main). This level was confirmed by EPA's split
sample at a concentration of 122 ppb and was significantly higher than the MCL of 5 ppb.
These results indicated a localized contamination of ground water by cadmium. This
contamination may be attributed to the Site, specifically the storm-drain sediments.
Several of the above metals were detected very infrequently (1 of 24 samples): antimony;
beryllium; cadmium; silver; and, thallium. Silver was detected in one distant downgradient
well, and both beryllium and thallium were detected only in the upgradient wells. Antimony
was detected at 582 ppb in the ground water directly beneath the location of the inactive
industrial leaching pools, but was not detected in any of the Site soils. (While the New
York State ground-water protection criterion for this metal is 3 ppb, the detection limits for
the ground-water analyses were 35 to 50 ppb. Therefore, the contamination by this metal
is not adequately defined.)
The metals which were detected in the ground water more frequently, total chromium and
hexavalent chromium, showed some association with the Site, however, these results are
difficult to interpret since a New York State Superfund Site, Astro Electroplating, is located
-9-
-------
adjacent to the Tronic Plating Superfund Site and appears to be contaminated with
chromium. For the remaining two metals which were detected more frequently, the nickel
data show some association of the metal with the Site, whereas lead data, which include
concentrations ranging from 4 to 75.5 ppb, with many values above the 15 ppb federal action
level, indicate source(s) located upgradient from the Site. For nickel only one sample at 114
ppb exceeded EPA's proposed MCL of 100 ppb.
Surface Soils
The industrial waste waters were discharged from the Tronic Plating facility to the
subsurface environment through leaching pools and storm drains. This disposal history
suggests that surface soils are not contaminated with Site contaminants, although these soils
were not chemically characterized in the RI. In addition, most of the Site surface is paved,
precluding erosion or other transport of surface soil layers. Also, contaminants in subsurface
soils are unlikely to be transported to the surface.
Contaminant Releases to Air
The primary contaminated media at the Site were the storm-drain sediments and subsurface
soils. The extensive cover of the Site by pavement and building and the remote subsurface
location of the contaminants precludes fugitive paniculate or vapor emissions from the Site.
Low levels of VOCs in the subsurface soil samples also indicate that the volatilization to
ambient air will be negligible. During the RI, ambient air in the work space was monitored
using the HNU analyzer. During the drilling of the industrial leaching pool, storm drain,
and monitoring well borings, VOCs were detected only once at 0.5 ppm level.
SUMMARY OF SITE RISKS
The baseline risk assessment was conducted to estimate the human health and ecological
risks associated with current and future Site conditions if no remedial action was taken. The
baseline risk assessment was based upon the results of the RI. (See Table F for the
summary statistics developed from the RL)
Human Health Risk Assessment
A four-step process was utilized for assessing Site-related human health risks for a
reasonable maximum exposure scenario: Hazard Identification- identified the contaminants
of concern (COCs) at the Site based on several factors such as toxicity, frequency of
occurrence, and concentration; Exposure Assessment- estimated the magnitude of actual
and/or potential human exposures, the frequency and duration of these exposures, and the
pathways (e.g., ingesting contaminated well-water) by which humans are or could be
potentially exposed to the COCs; Toxicity Assessment— determined the types of adverse
health effects associated with chemical exposures, and the relationship between magnitude
•10-
-------
of exposure (dose) and severity of adverse effects (response); and, Risk Characterization-
summarized and combined outputs of the exposure and toxicity assessments to provide a
quantitative (e.g., one-in-a-million excess cancer risk) assessment of Site-related risks.
The baseline risk assessment began with selecting the COCs which would be representative
of Site risks. (See Table A.) The summary statistics for these COCs are presented in Table
F. These contaminants included: VOCs such as acetone and chlorinated alkanes and
alkenes, semivolatile organic compounds such as phthalates and polynuclear aromatic
hydrocarbons, and 19 metals and cyanide. In general the most toxic, mobile and persistent
contaminants, and those found frequently and at high concentrations at the Site are selected
as COCs. However, the method used in this baseline risk assessment was conservative,
favoring the inclusion of most contaminants in the analysis rather that the selection of only
a few chemicals.
The baseline risk assessment evaluated the health effects which could result from exposure
to contamination as a result of the following exposure scenarios: 1) ingestion of ground-
water by a worker in the future; 2) incidental ingestion of and dermal contact with on-Site
subsurface soils by an excavation worker in the future and a utility worker at present and
in the future; 3) incidental ingestion of and dermal contact with storm-drain sediments by
an excavation worker in the future and a utility worker at present and in the future; and,
4) dermal contact with storm drain water by a utility worker at present and in the future.
(See Table B.) Given that public drinking water supply wells are more than 2 miles
downstream, residential exposures were considered unlikely. However, given the presence
of private wells on nearby commercial/industrial properties, ingestion of ground water by
local workers was considered. The area surrounding the Site is commercial/industrial,
therefore residential soil exposure scenarios were not considered.
EPA's acceptable cancer risk range is 10~* to 10"*. This should be interpreted to mean that
an individual may have approximately one in ten thousand to one in a million increased
chance of developing cancer as a result of Site related exposure to a carcinogenic compound
over a 70 year lifetime.
The results of the baseline risk assessment for this Site indicated that the highest
carcinogenic risks (See Table £.) were attributable to a ground-water ingestion exposure
scenario. These risks were within EPA's guidelines for an acceptable exposure. Four
contaminants showed risks that exceeded a 1x10* risk level: 1,1-DCE, PCE, TCE, and
arsenic. The cumulative risk associated with this exposure was 6.0 x 10"5, which means that
6 additional persons out of 100,000 people could be at risk of developing cancer if the Site
contamination was not remediated. The cumulative carcinogenic risks associated with the
exposures to Site subsurface soils and storm-drain sediments did not exceed 1x10*. The
highest risk due to exposure to subsurface soil was 2.0 x 10*7 and to sediments was 9.8 x 10*.
These risks are within EPA's acceptable risk range.
-11-
-------
The health hazards of non-carcinogens are assessed by comparing the chronic daily intake
(GDI) of a contaminant to its reference dose (RfD); the RfD (See Table C) being a bench-
mark for safety by virtue of its being based on the contaminant's threshold for causing
adverse health effects, to which multiple safety factors are added. The ratio of the chronic
daily intake to the reference dose (CDI/RfD) is referred to as the Hazard Quotient (HQ).
An HQ > 1 may be associated with adverse health effects. To assess the overall potential
for noncarcinogenic effects posed by simultaneous exposure to multiple contaminants, EPA
has developed the Hazard Index (HI), which is the sum of all HQs within a particular
exposure pathway. In the event that the addition of multiple subthreshold HQs (Le., HQ
< 1) exceeds an HI - 1, adverse health effects may result if the individual contaminants are
believed to share a similar mechanism-of-action or toxic endpoint
The results of the evaluation of the noncarcinogenic hazards for this Site indicated that only
the chronic HI of 1.8 for the ground-water ingestion exposure scenario was above one. (See
Table D.) The His for all other exposure scenarios were below 1.
The HI of 1.8 was a cumulative value largely derived from chemical specific HQs for
antimony (.67), arsenic (25) and TCE (22). The other metals which contributed to the risk
included aluminum, cadmium, and hexavalent chromium. The computation of this HI
included the conservative assumption that the HQs were additive. The contaminants which
contributed significantly to the HI, however, affect different target organ systems and the
exposures to these contaminants would result in different lexicological effects, except for
antimony and arsenic, which affect similar target organs. Adding chemical specific HQs
overestimated the Site risks. Further reducing the significance of the Site related chronic
noncarcinogenic hazards from the ground-water ingestion scenario was the fact that some
contaminants which contributed to the HI were detected infrequently; antimony in 2/24
samples, arsenic in 2 of 24 samples and cadmium in 1 of 24 samples.
The estimates of risks/hazards associated with the actual or threatened releases of
hazardous substances from this Site did not indicate an existing or potential threat to public
health, welfare or the environment.
Uncertainties
The procedures and inputs used to assess risks in this evaluation, as in all such assessments,
are subject to a wide variety of uncertainties. In general, the main sources of uncertainty
include:
• environmental chemistry sampling and analysis
• environmental parameter measurement
- fate and transport modelings
• exposure parameter estimation
- lexicological data.
-12-
-------
Uncertainty in environmental sampling arises in part from the potentially uneven
distribution of chemicals in the media sampled. Consequently, mere is significant
uncertainty as to the actual levels present. Environmental chemistry-analysis error can stem
from several sources including the errors inherent in the analytical methods and
characteristics of the matrix being sampled.
Uncertainties in the exposure assessment are related to estimates of how often an individual
would actually come in contact with the chemicals of concern, the period of time over which
such exposure would occur, and in the models used to estimate the concentrations of the
chemicals of concern at the point of exposure.
Uncertainties in lexicological data occur in extrapolating both from animals to humans and
from high to low doses of exposure, as well as from the difficulties in assessing the toxicity
of a mixture of chemicals. These uncertainties are addressed by making conservative
assumptions concerning risk and exposure parameters throughout the assessment. As a
result, the Risk Assessment provides upper-bound estimates of the risks to populations near
the Site, and is highly unlikely to underestimate actual risks related to the Site.
More specific information concerning public health risks, including a quantitative evaluation
of the degree of risk associated with various exposure pathways, is presented in the Risk
Assessment Report
Actual or threatened releases of hazardous substances from this site, if not addressed by the
selected alternative or one of the other remedial measures considered, may present an
imminent and substantial endangerment to the public health, welfare, and the environment
through the continued leaching of contaminants from the landfill.
Ecological Risk Assessment
The Site and its vicinity have been heavily modified for industrial use. The only potential
habitat is the wooded area 300 feet south of the Site. This area is owned by Pinelawn
Cemetery and will most likely be cleared within fifteen years. In addition, known
contamination at the Site is limited to the subsurface.
Based on these observations, the potential risk of exposure of wildlife to Site contaminants
was assumed negligible.
STATE ACCEPTANCE
The State of New York concurs with EPA's selected no further action alternative. Their
letter of concurrence is attached as Appendix IV.
•13-
-------
COMMUNITY ACCEPTANCE
There were no comments received during the public comment period which began July 28
and ended August 27,1993. The only two attendees at the public meeting held by EPA in
the Babylon Town Hall on August 24,1993 were the fire marshall and a representative of
the Town of Babylon Bureau of Environmental Control. These two officials concurred with
the remedy.
DESCRIPTION OF THE "NO FURTHER ACTION" REMEDY
Based upon the review of all available data and findings of the RI and the removal
conducted at the Site, EPA has determined that a no further action remedy is protective of
human health and the environment
The baseline risk assessment indicated that the levels of contaminants present in the Site
sediments, soils and ground water presented risks which fall within EPA's acceptable risk
range. In addition, although ground-water sampling results indicated some occurrence of
contaminants exceeding MCLs, the distributions of these contaminants indicated either off-
site sources or localized contamination. With the exception of cadmium, the ground-water
contaminants could not be associated with potential sources at the Site.
The removal action performed by the PRP achieved the removal of cadmium from the Site
sediment which acted as a source of contamination to the ground water. Cadmium was
present in the ground water at one sampling location in concentrations exceeding State and
Federal primary drinking water standards or MCLs. Therefore, since the potential source
of cadmium to the ground water was removed, concentrations of cadmium in the ground
water at the Site should not increase. This action also achieved the removal of lead and
chromium and any other potential ground-water contaminants found in the contaminated
sediments of the storm drains and associated overflow drains, the sanitary leaching pool and
the drywell. Confirmatory samples taken from the bottom of the excavations ensured that
these goals were met. The removal was considered effective because it met the cleanup
goals developed by EPA and NYSDEC.
