STATEMENT OF BASIS AND PURPOSE

This decision document presents the final remedy to address Area K groundwater at the Naval Air
Engineering Station in Lakehurst, New Jersey.  The selected alternative was chosen in accordance
with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), as
amended by the Superfund Amendments and Reauthorization Act (SARA) and, to the extent
practicable, the National Oil and Hazardous Substance Pollution Contingency Plan.

This decision is based on information contained in the Remedial Investigation (RI) Report (October
1992), the Endangerment Assessment (EA) Report (October 1992), the Focused Feasibility Study
for Area K Groundwater (31 July 1996), and the Proposed Plan for Area K Groundwater (5
February 1997). These reports and other information used in the remedy selection process are part
of the Administrative Record file for Area K, which is available for public review at the Ocean
County Library in Toms River, New Jersey.

This document provides background information on the Area, presents the selected alternative,
reviews the public's response to the Proposed Plan and provides answers to comments raised during
the public comment period.

Both the United States Environmental Protection Agency (USEPA), Region II Deputy
Administrator and the Commissioner of the New Jersey Department of Environmental Protection
(NJDEP) concur with the selected remedy.

DESCRIPTION OF THE SELECTED REMEDY

The selected alternative to address groundwater at Area K is: Limited pumping of groundwater
with sprinkler irrigation and monitor contaminants through sampling and analysis.

The objectives of the proposed actions are to: 1) provide hydraulic containment of the highest
levels of contamination; 2) treat higher levels of groundwater contamination via spray irrigation; 3)
and, to monitor the levels of contaminant in the groundwater to monitor effectiveness.

-------
STATUTORY DETERMINATIONS

This final action for Area K is protective of human health and the environment. The results of this
action will attain Federal and State applicable or relevant and appropriate requirements (ARARs).

SITE DESCRIPTION
The Naval Air Engineering Station (NAES) is located in Jackson and Manchester Townships,
Ocean County, New Jersey, approximately 14 miles inland from the Atlantic Ocean (Figure 1).
NAES is approximately 7,400 acres and is bordered by Route 547 to the east, the Fort Dix Military
Reservation to the west, woodland to the north (portions of which are within Colliers Mill Wildlife
Management Area), Lakehurst Borough and woodland, including the Manchester Wildlife
Management Area, to the south. NAES and the surrounding area are located within the Pinelands
National Reserve, the most extensive undeveloped land tract of the Middle Atlantic Seaboard. The
groundwater at NAES is currently classified by NJDEP as Class I-PL (Pinelands).

NAES lies within the Outer Coastal Plain physiographic province, which is characterized by gently
rolling terrain with minimal relief. Surface elevations within NAES range from a low of
approximately 60 feet above mean sea level in the east central part of the base, to a high of
approximately 190 feet above mean sea level in the southwestern part of the base. Maximum relief
occurs in the southwestern part of the base because of its proximity to the more rolling terrain of the
Inner Coastal Plain.  Surface slopes are generally less than five percent.

NAES lies within the Toms River Drainage Basin. The basin is relatively small (191  square miles)
and the residence time for surface drainage waters is short. Drainage from NAES discharges to the
Ridgeway Branch to the north and to the Black and Union Branches to the south. All three streams
discharge into the Toms River. Several headwater tributaries to these branches originate at NAES.'
Northern tributaries to the Ridgeway Branch include the Elisha, Success, Harris and Obhanan
Ridgeway Branches. The southern tributaries to the Black and Union Branches include the North
Ruckles and Middle Ruckles Branches and Manapaqua Brook. The Ridgeway and Union Branches
then feed Pine  Lake; located approximately 2.5 miles east of NAES before joining Toms River.
Storm drainage from NAES is divided between the north and south, discharging into the Ridgeway
Branch and Union Branch, respectively. The Paint Branch, located in the east-central part of the
base, is a relatively small stream which feeds the Manapaqua Brook.

Three small water bodies are located in the western portion of NAES: Bass Lake, Clubhouse Lake,
and Pickerel Pond.  NAES also contains over 1,300 acres of flood-prone areas, occurring primarily
in the south-central part of the base, and approximately 1,300 acres of prime agricultural land in the
western portion of the base.

There are 913 acres on the eastern portion of NAES that lie within Manchester Township and the
remaining acreage is in Jackson Township. The combined population of Lakehurst Borough,
Manchester and Jackson Townships, is approximately 65,400, for an area of approximately 185
square miles. The average population density of Manchester and Jackson Townships  is  169
persons per square mile.

-------
The areas surrounding NAES are, in general, not heavily developed. The closest commercial area
is located near the southeastern section of the facility in the borough of Lakehurst.  This is primarily
a residential area with some commercial establishments but no industry. To the north and south are
State wildlife management areas which are essentially undeveloped. Adjacent to and south of
NAES are commercial cranberry bogs, the drainage from which crosses the southeast section of
NAES property.

For the combined area of Manchester and Jackson Townships, approximately 41 percent of the land
is vacant (undeveloped), 57 percent is residential, one percent is commercial and the remaining one
percent is industrial or farmed. For Lakehurst Borough,  83 percent of the land is residential,  11
percent is vacant, and the remaining 6 percent commercially developed.

In the vicinity of NAES, water is generally supplied to the  populace by municipal supply wells.
Some private wells exist, but these are used primarily for irrigation and not as a source of drinking
water.  In Lakehurst Borough there  is a well field consisting of seven 50-foot deep wells, located
approximately two-thirds of a mile south of the eastern portion of NAES. Three of the seven wells
(four of the wells are rarely operated) are pumped at an average rate of 70 to 90 gallons per minute
and supply drinking water for a population of approximately 3,000. Jackson Township operates
one supply well in the Legler area, approximately one-quarter mile north of NAES, which supplies
water to a very small population (probably less than 1,000) in the immediate vicinity of NAES.

The history of the site dates back to 1916, when the Eddystone Chemical Company leased property
from the  Manchester Land Development Company to develop an experimental firing range for the
testing of chemical artillery shells. In 1919, the U.S. Army assumed control of the site and named
it Camp Kendrick.  Camp Kendrick was turned over to the Navy and formally commissioned Naval
Air Station (NAS) Lakehurst, New Jersey on June 28, 1921. The Naval Air Engineering Center
(NAEC)  was moved from the Naval Base, Philadelphia to Lakehurst in December 1974. At that
time,  NAEC became the host activity, thus, the new name NAEC.  In January  1992, NAEC was
renamed  the Naval Air Warfare Center Aircraft Division Lakehurst (NAW6ADLKE), due to a
reorganization within  the Department of the Navy. In January 1994, the NAWCADLKE was
renamed  the Naval Air Engineering Station (NAES), due to continued reorganization within the
Department of the Navy.

Currently, NAES's mission is to conduct programs of technology development, engineering,
developmental evaluation and verification, systems integration, limited manufacturing,
procurement, integrated logistic support management, and fleet engineering support for Aircraft-
Platform  Interface (API) systems. This includes terminal guidance, recovery, handling, propulsion
support, avionics support, servicing and maintenance, aircraft/weapons/ship compatibility, and
takeoff. The Station provides, operates, and maintains product evaluation and verification sites,
aviation and other facilities, and support services (including development of equipment and
instrumentation) for API systems and other Department of Defense programs. The Station also
provides  facilities and support services for tenant activities  and units as designed by appropriate
authority.

-------
NAES and its tenant activities now occupy more than 300 buildings, built between 1919 and 1996,
totaling over 2,845,000 square feet. The command also operates and maintains: two 5,000-foot
long runways, a 12,000-foot long test runway, one-mile long jet car test track, four one and one-
quarter mile long jet car test tracks, a parachute jump circle, a 79-acre golf course, and a 3,500-acre
conservation area.

In the past, the various operations and activities at NAES required the use, handling, storage and
occasionally the on-site disposal of hazardous substances. During the operational period of the
facility, there have been documented, reported or suspected releases of these substances into the
environment.

SITE HISTORY

Area K. is located in the northwestern portion of NAES and includes Sites 4, 5, 8, 27 and 30 (See
Figure 2). Area K encompasses the receiving ends of the five Recovery Systems Test Sites
(RSTS) test tracks. The tracks are used to test arresting gear and barricade systems. A weighed
cart is propelled  by a jet car into the  arresting system.  The tracks are generally surrounded by
grass-covered and wooded areas.  A wetland area is present in the north/northeast portion of Area
K and the NAES property line forms the northern boundary of Area K. The Obhanan Ridgeway
Branch flows through the northern section of Area K, near the facility boundary. The general
direction of groundwater flow in Area K is to the northeast. Two non-potable water supply wells
are located in Area K. SW-22 in the  southern portion of the Area, at the end of Track 4, and SW-
19 in the northeastern portion of the Area, at the end of Track 1.

The results of previous investigations and removal actions at former Sites 5, 27 and 30 in Area K
have documented the absence of any  significant soil contamination posing a threat to human
health or the environment.  Proposed Plans of "no further action" were prepared for these sites
and released for public comment.  Following the 30 day public comment period, the Navy with
the concurrence of the USEPA and NJDEP, issued  "no further action" Records of Decision for
these sites dated September 16, 1991  and December 10, 1991.

DESCRIPTIONS OF REMAINING SITES

SITE 4T "Deadload Maintenance Shop (Building 372). Arresting End of Track 2. A solvent
storage rack was located at this  site, directly behind (to the northeast of) Building 372, the
Deadload Maintenance Shop, between the arresting ends of test tracks Nos. 2 and 3 (Figure 3).
Between 1958 and 1980, 55 gallon drums containing dry cleaning solvent and lubricating oil
were stored at this site.  Barrels reportedly leaked while in storage, creating a 10-foot by 20-foot
black discoloration of the soil immediately below the rack.  The total amount of leakage is
unknown. In the early 1980s, a secondary containment was constructed for storage of hazardous
material/wastes. All stained soil was removed and replaced with clean fill. It was reported that
propylene glycol may have also been used at the site.

 Special features include:
    •There is a shallow groundwater table at Site 4 at a depth of approximately 9 feet below the
    ground surface.
    •Groundwater flow is in a generally northeast direction, parallel to the northern NAES
    boundary.
    •The Obhanan Ridgeway Branch is located approximately 400 feet north (sidegradient) of
    Site 4.  A concrete drainage swale, which discharges into the Obhanan Ridgeway Branch.
    passes within about 100 feet of Site 4.

 Site 8. "Arresting End of RSTS Track No. 1. Building 529":  This site is located five feet
 northeast of Building 529 at the end of RSTS Track No. 1, and comprises a 5 by 5 feet area (see
 Figure 4). Maintenance activities at RSTS Track No. 1 produced unknown wastes which were
 reportedly disposed of by pouring onto the dirt next to Building 529. A small solvent storage
 facility was also located next to Building 529 which operated continuously between  1957 and
 1981.  Some leakage of containers reportedly occurred at this site.  However, no visible signs of
 soil contamination were present during a 1980-1981 site investigation. In 1981, a secondary
 containment facility was constructed for storage of hazardous material/wastes.

 Special features include:
    •Site 8 is located approximately 2,000 feet from the nearest (northern) NAES boundary.
    •There is a shallow groundwater table at Site 8 at a depth of approximately 6 feet below the
    ground surface.
    •The general direction of groundwater flow at  the site  is to the northeast.
    •The Obhanan Ridgeway Branch is located approximately 300 feet north of Site 8.
    •There is a non-potable water supply well, SW-19, located underneath Building 354 which
    supplies water for the Track 1 restroom facility. Bottled drinking water is supplied to
    personnel at the site.
INITIAL INVESTIGATIONS

As part of the DOD Installation Restoration Program and the Navy Assessment and Control of
Instillation Pollutants (NACIP) program, an initial Assessment Study was conducted in 1983 to
identify and assess sites posing a potential threat to human health or the environment due to
contamination from past hazardous materials operations.

Based on information from historical records, aerial photographs, field inspections, and personnel
interviews, the study identified a total of 44 potentially contaminated sites. An additional site,
Bomarc, was also investigated by NAES.  The Bomarc Site is the responsibility of the U.S. Air
Force and is located on Fort Dix adjacent to the western portion of NAES. A Remedial
Investigation (RI) was recommended to confirm or deny the existence of the suspected
contamination and to quantify the extent of any problems which may exist. Following further
review of available data by Navy personnel, it was decided that 42 of the 44 sites should be
included in the Remedial Investigation. Two potentially contaminated sites, an ordnance site (Site
41) and an Advanced Underground Storage Facility (Site 43), were deleted from the Remedial

 Investigation because they had already been rehabilitated. In 1987 NAES was designated as a
 National Priorities List (NPL) or Superfund site under the federal Comprehensive Environmental
 Response, Compensation and Liability Act (CERCLA).

 REMEDIAL INVESTIGATIONS

 SITE 4
 Investigations at this site was initiated prior to 1984 with the installation of 2 monitoring wells.
 Monitoring well AS was installed approximately 300 feet in a general down gradient direction
 from the site. Well AT was installed about 250 feet south-southwest, but not directly upgradient.
 of the site. (See Figure 5).

 Phase I Remedial Investigation
 During Phase I (1985-1986) investigations, stained soil was observed behind Building 372
 during visual inspection of the site. In June 1988, soil gas and groundwater screening surveys
 revealed elevated levels of petroleum and chlorinated hydrocarbons in soil gas and shallow
 groundwater at the site.

 Phase II Remedial Investigation
 In Phase II, (Aug-Dec 1988), analysis of groundwater samples collected from well AS and a new
 well installed about 50 feet down gradient from the site (GY) revealed high levels of vinyl
 chloride and slightly elevated levels of chromium and mercury.  The high levels of vinyl chloride
 were not confirmed by an EPA split sample nor by another round of sampling at the same well.
 Analyses of three soil samples collected from test pits excavated at the site revealed no
 contamination.

 Confirmation Sampling
 In July 1990, filtered and unfiltered groundwater samples were collected from well AS to
 confirm the elevated levels of chromium and mercury detected in the well-during Phase II.
 Chromium was detected in the unfiltered sample at a concentration of 14.3 ug/1 (below the NAES
 established background level of 324 ug/1) and was not detected in the filtered sample. Mercury
 was not detected in either sample.

 Phase III Remedial Investigation
 In Phase III (July 1991-March 1992), groundwater samples were collected from three different
depths, using the Hydropunch™, at one location upgradient of the site and three locations down
gradient of the site. Chlorinated volatile organic compounds (VOCs) and low levels of benzene
were detected in a. shallow groundwater sample from a location 800 feet northeast (down
gradient) of the site.  Vinyl chloride was not detected in this sample.  No chromium or mercury
was detected in the analysis of a filtered sample collected from well AS. Of the samples
collected from three test pits near the former solvent storage rack, contaminants were detected
which exceeded EPA acceptable risk levels or NJDEP soil criteria.

 SITES
 In 1980, an EPA contractor performed a field investigation at this site, consisting of several
 organic vapor analyzer (OVA) measurements in 3.5 to 4 feet deep test pits. OVA levels in the
 area around Building 529 exceeded 1,000 parts per million (ppm).  A gas chromatographic
 analysis indicated the probable presence of trichloroethene and, at much lower concentrations.
 tetrachloroethene. The contamination appeared to be confined to the area immediately outside
 Building 529. Monitoring well F was installed at the location of the reported disposal site at the
 northeastern comer of Building 529.  The well was monitored by NAES for the presence of
 floating product. None was detected.

 Phase I Remedial Investigation
 In Phase I investigations (1985 - 1986), no visual evidence of soil contamination was observed
 during examination of the site. Analysis of groundwater samples collected from monitoring well
 F at the site, and supply well SW-19, down gradient from the site, revealed no contamination.

 Phase II Remedial Investigation
 In Phase II (Aug-Dec 1988), analysis of groundwater samples collected at the site revealed the
 presence of two VOCs and mercury in an unfiltered sample. No contamination was detected in a
 soil sample collected from a boring drilled at the site.

 Phase III  Remedial Investigation
 During Phase III investigations (July 1991- April 1992), analysis of groundwater samples
 collected in the area of Site 8 revealed sporadic detections of chlorinated VOC contamination.
 The source of VOC contamination appears to be the disposal and/or spillage of liquid wastes,
 including solvents, onto the ground at Sites 4 and 8. The plume had a maximum width of 2,100
 feet at this point. Aromatic VOCs (benzene, toluene, ethylbenzene and xylenes (BTEX)) were
 detected at very low concentrations in groundwater samples collected to the east, west and
 southwest of Site 8.  The exact source of the aromatic VOCs in groundwater has not been
 determined but is not believed to be a prolonged or systematic release based on site history.  Soil
 samples collected from test pits excavated at Site 8 contained low levels of chlorinated VOCs,
 well  below NJ Soil Cleanup Criteria, and no visual evidence of soil contamination was noted.

 Additional Investigations
 A workplan for groundwater monitoring was developed, dated January 1994, when it was
 determined that existing groundwater sampling data was not sufficient to determine the preferred
 alternative for the site. Pursuant to the workplan, thirteen additional monitoring wells (KE
 through KQ) were installed between  18 and 29 November 1994 within Area K (See Figure 5).
 Four of these wells, KN, KO, KP and KQ, established a down gradient "line of compliance" for
 the plume. These wells supplemented the existing network of 11 wells and aided in the
 verification of data collected from some of the  14 Hydropunch™ sampling locations in Area K.

The new well network was subsequently sampled semi-annually for VOC analysis. All wells
were sampled on February 21, 1995,  October 26,  1995, and April 24, 1996 (the April results
were reported in May 1996). The line of compliance wells were resampled on May 23, 1995 to

-------
 verify the results of the February 1995 sampling event.  Additionally, well KE was sampled on
 February 21, 1996.

 The results of these sampling events have verified the presence of chlorinated solvents and
 BTEX compounds (see Table I for a summary of results). A full set of sampling results can be
 found in Appendix B of the Focused Feasibility Study for Area K. From this data, there appears
 to be a preferential path of migration of the contaminants between wells KE and KN. Sampling
 of these wells has not revealed the presence of vinyl chloride, but has shown other intermediate
 breakdown products of trichloroethene. It appears that the source, once located immediately
 northeast of building 373 (Site 4), has migrated further northeast.  Wells AT and KF at Site 4
 reveal little or no contamination (below 4 parts per billion (ppb)). Well GY at Site 4 showed a
 level of 13.62 ppb total VOCs in the May 1996 round. The highest levels of contamination in
 Area K are found in wells KE, KG, and KI (50.49 ppb February 1995, 26.36 ppb May 1996 and
 42.7 ppb February 1995 total VOCs respectively).  Detected levels of total VOCs in individual
 wells can vary significantly  with each sampling round. For example, shallow well JA had a level
 of 15.3 ppb total VOCs in the October  1995 round while the May 1996 analysis did not show
 any detectable levels of VOCs.

 In the down gradient line of compliance wells low levels of chloroform, cisl,2- dichloroethene.
 and 1,1-dichloroethane have been detected sporadically.  Other contaminants such as
 dichlorodifluoromethane,  1,2,3-trimethylbenzene, methylene chloride, benzene, xylenes, and
 isopropyltoluene have been detected infrequently. Only chloroform and cisl,2-dichloroethene
 have been detected at levels  slightly exceeding ARARs in wells KN, KO and KQ. However,
 these levels have been inconsistent.

 Side-gradient wells to the west of the Area (wells KM, KJ and pair JC/JD) reveal no
 contamination. Therefore, there is no likelihood of off-base contamination to the west.

The groundwater cleanup standards for NAES consist of Federal Maximum Contaminant Levels
 (MCLs) and State  Groundwater Quality Criteria, MCLs  are federally enforceable maximum
contaminant levels allowable in public drinking water supplies. They have been established from
health-based data by EPA's Office of Drinking Water Regulations (40  CFR 141) established
 under the authority of the Safe Drinking Water Act.

 On January 13, 1993, the revised New Jersey Administrative Code 7:9-6 which includes the
Groundwater Quality Criteria was promulgated. The criteria establish the  groundwater
classifications for the Pinelands, including Class I-PL for the Preservation Area. The actual
groundwater criteria is natural quality. However, for some constituents natural quality is often
much lower than can be measured in a laboratory, therefore, some measureable criteria are
necessary to determine compliance.  Practical Quantitation Levels (PQLs)  are the lowest
concentration of a  contaminant that can  be reliably achieved among laboratories within specified
 limits of precision and accuracy during routine laboratory operating conditions.  The PQLs will
be used to determine compliance with the Groundwater Quality Criteria for Class I-PL
groundwater.

Summary of Findings
A plume of chlorinated volatile organic contamination (VOCs), primarilytrichloroethene and
tetrachloroethene, is present in shallow groundwater at Area K and encompasses both Site 4 and
Site 8 (See Figure 5). The contamination is attributable to parts cleaning operations and solvent
storage practices occurring in the past at Sites 4 and 8 (see site descriptions). The plume begins
at Site 4 and widens, and decreases in ccncentration, in the down gradient (northeast) direction.
The maximum width of the area of concern has varied with sampling rounds but has been
between 2,100 feet to 1200 feet. Since it was determined likely that the low levels of
contamination present in this area are discharging into the wetland region immediately down
gradient, four line of compliance wells were installed in the down gradient wetlands.  Sporadic
detectable levels of VOCs have been detected at the Line of Compliance wells approximately
900 feet down gradient from Site 8.

The primary contaminants found in groundwater at Area K are trichloroethene and
tetrachloroethene (at levels of 40 part per billion (ppb) or less for each).  Based on groundwater
monitoring of the down gradient and sidegradient line of compliance wells, it is unlikely that
contamination has migrated past NAES boundaries.
                                                                                    15

 HIGHLIGHTS OF COMMUNITY PARTICIPATION

 A draft Proposed Plan was first issued for comments on 30 September, 1996.  On December 21
 and 22, 1996, a newspaper notification inviting public comment on the Proposed Plan appeared
 in The Ocean County Observer and The Asbury Park Press. The public notice summarized the
 Proposed Plan and the preferred alternative. The announcement also identified the time and
 location of a Public Meeting and specified a public comment period, and the address to which
 written comments could be sent. Public comments were accepted from January 7, 1997 to
 February 7, 1997.  The newspaper notification also identified the Ocean County Library as the
 location of the Information Repository.

 A Public Meeting was held on January 15, 1997 at the Manchester Branch of the Ocean County
 Library at 7:00 p.m..  At this meeting representatives from the Navy, USEPA and NJDEP were
 available to answer questions concerning Area K and the preferred alternative.  A list of
 attendees is attached to this Record of Decision as Appendix A. Comments received and
 responses provided during the public hearing are included in the Responsiveness Summary,
 which is pan of this Record of Decision.  A transcript of the meeting is available as part of the
 Administrative Record.

 During the public comment period from January 7, 1997 through February 7, 1997. no written
 comments were received, from the public, pertaining to Area K.  On February 4, 1997, the
 NJDEP submitted additional  comments to the Proposed Plan for Area K.  The Proposed Plan was
 revised to include these comments.  A copy of the final Proposed Plan for Area K, dated
 February 5, 1997, has been placed in the Administrative Record for NAES located at the Ocean
 County Library, Toms River, NJ.

This decision document presents the selected alternative (i.e., spray irrigation and long term
monitoring) for Area K, chosen in accordance with CERCLA, as amended by SARA and, to the
 extent practicable, the National Contingency Plan (NCP).  The decision for Area K is based on
the information contained in  the Administrative Record, which is available for public review at
 the Ocean County Library, 101 Washington Street, Toms River, New Jersey.
SCOPE AND ROLE OF RESPONSE ACTION

Studies conducted in Area K from 1985 to the present show that the groundwater in this area had
been contaminated with various VOCs as a result of past operations dating back to the 1950s
through the 1970s. The Navy implemented groundwater use restrictions and has conducted
monitoring for the last three years.

Previous Remedial Actions

The results of previous investigations and removal actions at former Sites 5, 27 and 30 in Area K
have documented the absence of any significant soil contamination posing a threat to human
health or the environment. Proposed Plans of "no further action" were prepared for these sites

                                                                                   16

 and released for public comment. Following the 30 day public comment period, the Navy with
 the concurrence of the USEPA and NJDEP, issued a "no further action" Record of Decision for
 these  sites.

 SUMMARY OF SITE RISKS

 In April 1992, a facility-wide endangerment assessment for NAES was conducted.  The objective
 of this Endangerment Assessment (EA) was to assess the potential current and future human
 health risks and potential environmental impacts posed by contaminated soils, groundwater,
 sediment, and surface water at NAES. Based on available information, NAES was considered to
 be a potential public health concern because of the risk to human health caused by the possibility
 of exposures to hazardous substances via contaminated groundwater, soil, sediment and surface
 water.
AREA K RISK

This is a summary of the Endangerment Assessment (EA) findings for groundwater in Area K.
The assessment of this site was conducted using all available data generated during previous
remedial investigations (RI). This summary will discuss (1) the chemicals identified as
contaminants of concern (COCs), (2) the land use assumptions upon which estimates of potential
human exposure to site contaminants are based, (3) the quantitative estimates of carcinogenic
risk and noncarcinogenic hazard, and (4) a summary interpretation of the EA findings with
regard to need for site remediation.
CONTAMINANTS OF CONCERN

For Area K groundwater, chemicals of concern (COCs) include:  trichloroethene,
tetrachloroethene, cis 1,2-dicloroethene, 1,1-dichloroethane, 1,1,1-trichloroethane, benzene,
toluene, xylenes, and chloroform. These chemicals are cleaning solvents and their breakdown
products and volatile constituents found in gasoline.

LAND USE AND EXPOSURE ASSUMPTIONS

Four different scenarios representing current and potential future land uses were evaluated to
assess applicability to the site.  Evaluated scenarios included military, light industrial,
construction and residential land uses. For each of these scenarios, human exposure is effected
by mechanisms that include direct contact, inhalation and ingestion.

Based on current land use conditions within Area K, a light industrial land use scenario was
quantified for direct exposure to contaminated groundwater via incidental ingestion.

Future residential land use conditions were evaluated as part of the risk characterization for Area
K groundwater.

                                                                                    17

-------
 HUMAN HEALTH RISK AND HAZARD FINDINGS

 The endangerment assessment for the groundwater media addressed the cumulated groundwater
 data associated with Sites 4 and 8. The COCs included after the screening process are
 tetrachloroethene, trichloroethene, cisl,2-dichloroethene, 1,1-dichloroethane, 1,1,1-
 trichloroethane. benzene, toluene, xylenes, and chloroform.

 Under a current light industrial  scenario, the carcinogenic risk contributed by the COCs listed
 above was 2.78x10° and the Hazard Quotient was 0.061. Under a future residential scenario, the
 risk was calculated as 5.74xlO"5 and Hazard Quotient of 0.155.

 Both these potential future land use scenarios show a risk within EPA's acceptable risk range of
 10"6 to 10"4 but above New Jersey's acceptable risk of 10"6 . The associated Hazard Quotients are
 under 1.0.  There is currently no pathway between groundwater and humans in this area.
 Without a pathway, risks associated with ingestion of groundwater is unlikely. In fact,  workers
 in this area are supplied with bottled drinking water based upon the high iron, turbidity  and
 overall poor water quality from existing shallow wells in the area.

 ECOLOGICAL ASSESSMENT

 As part of the Endangerment Assessment, a Baseline Ecological Evaluation (BEE) was
 conducted to obtain a description of the ecosystems at NAES.

 Currently, it does not appear that groundwater is having an impact on the ecology of Area K.
The low levels of VOCs likely to be discharging to the wetlands are not expected to be a
significant present or future ecological impacts.
ENDANGERMENT ASSESSMENT SUMMARY

In summary, the results of the EA indicate that contaminant present in groundwater at Area K
pose a concern relative to potential future exposure populations.  Therefore, alternatives for tl'e
remediation of groundwater contamination at this area are warranted. No elevated risks
associated with contaminants in soil at Sites 4 and 8 were found. In addition, no adverse
ecological effects due to contamination at the individual sites were found.
SUMMARY OF REMEDIAL ALTERNATIVES

Under CERCLA, the selected alternative must be protective of human health and the
environment, cost effective, and in accordance with statutory requirements.  Permanent solutions
to contamination are to be achieved wherever possible.  The remedial alternatives considered for
the site are summarized below.  Detailed descriptions of the remedial alternatives can be found in
the FFS (31 July 1996), which is available in the Administrative Record for NAES.

                                                                                    18

-------
 The alternatives 1 through 6 were evaluated as final remedial alternatives for groundwater. All
 alternatives include the establishment of a Classification Exception Area (CEA) pursuant to
 NJAC 7:9-6.6.

 ALTERNATIVE 1:  NO ACTION
 Estimated Construction Cost:  SO
 Estimated Net O&M Cost:    SO
 Estimated Implementation Time Frame: Not applicable (N/A)
 Estimated Time to Completion:   N/A
 Estimated Cost to Completion:  SO

 This alternative involves no additional actions at Area K (Sites 4 and 8).  This alternative is
 evaluated as a baseline by which to compare other alternatives.
ALTERNATIVE 2: LONG TERM GROUNDWATER MONITORING
Estimated Construction Cost: $0
Estimated Net O&M Cost:   S8,860/yr.
Estimated Implementation Time Frame:  3 months
Estimated Time to Completion:  30 years
Estimated Cost to Completion:  5265,800

This alternative involves monitoring of groundwater contaminants. No contaminants would be
treated or contained. Area K has no continuing sources contributing to groundwater
contamination. Monitoring of the sites can be implemented by using previously installed
monitoring wells.

There are four shallow wells that make up the area's "line of compliance". These wells are
located on NAES property and sampling results of these wells will be used to monitor
compliance with applicable standards. These wells are currently monitored on a semi-annual
basis.

Monitoring would consist of taking samples from all monitoring wells at the sites semi-annually
for 5 years, followed by a comprehensive evaluation of the data. The sampling program would
be re-evaluated based on the results.  At that time a determination would be made if the remedy
was protective or if additional remediation is necessary.

The sampling data will be entered into a groundwater model to determine the rates of
contaminant movement and reduction, and to determine the placement of additional wells as
needed.
                                                                                  19

-------
 ALTERNATIVE 3:  NATURAL RESTORATION WITH LONG TERM MONITORING
 Estimated Cost of Study: $216,400
 Estimated Net O&M Cost: 8,860/yr.
 Estimated Implementation Time Frame:  6 months
 Estimated Time to Completion:  30 years
 Estimated Cost to Completion:  5482,200

 Natural restoration would involve groundwater monitoring as outlined in Alternative 2 and an
 additional one-time study to determine whether biological activity can sufficiently reduce
 contaminants to appropriate standards. The study, which would last for two years, would
 determine if microorganisms are present that can remove the contaminants at the site. A similar
 three-year study is currently underway at another area of similar groundwater contamination at
 the base (Areas I & J). A similar workplan would be followed for Area K.

 ALTERNATIVE 4: SOURCE REDUCTION THROUGH SPRINKLER IRRIGATION
 WITH LONG TERM MONITORING
 Estimated Construction Cost:  544,495
 Estimated Net O&M Cost:   $ 13,260/yr.
 Estimated Implementation Time Frame: 3 months
 Estimated Time to Completion:  10 years
 Estimated Cost to Completion:  $177,095

Sprinkler irrigation consists of pumping groundwater and spraying it in the air to volatilize
contaminants. Groundwater pumping would be implemented at the areas of highest groundwater
contamination. One or two wells would be installed to pump water from the aquifer and spray
irrigate the water. This technology would only be effective in the temperate months  (i.e. April -
September) to avoid freezing. Pumping of groundwater provides hydraulic containment of the
highest levels of contamination.  By reducing the highest areas of contamination, overall
treatment goals can be achieved faster and at lower total cost.  An air permit may be required for
this alternative.

ALTERNATIVE 5: SOURCE REDUCTION THROUGH IN-WELL AERATION WITH
LONG TERM MONITORING
Estimated Construction Cost: $129,000
Estimated Net O&M Cost:   S62,360/yr.
Estimated Implementation Time Frame: 3 months
Estimated Time to Completion:   15 years
Estimated Cost to Completion:  $327,900

In-well aeration is a technology  where air is injected inside the wellbore of the well.  The air
injection acts as an in-situ air stripper to remove dissolved volatile organic compounds. In-well
aeration would be implemented  at the areas of highest groundwater contamination. One or two
wells would be installed with sparging/ air blower systems. This technology would be effective
                                                                                20

-------
throughout the year, whereas sprinkler irrigation can only be accomplished a portion of the year.
The radius of influence of this aeration technology is limited and may not reduce levels as fast as
other aeration technologies that use pumping. However by reducing the highest areas of
contamination, overall treatment goals can be achieved faster and at lower total cost when
compared to long-term monitoring alone.

ALTERNATIVE 6:  GROUNDWATER PUMPING, PRETREATMENT FOR
INORGANICS, AIR STRIPPING, CARBON TREATMENT AND AQUIFER
RECHARGE
Estimated Construction Cost: 51,344,325
Estimated Net O&M Cost:     Sl40,000/yr.
Estimated Implementation Time Frame:  3 months
Estimated Time to Completion: 10 years
Estimated Cost to Completion: $2,744,325


With this alternative groundwater is pumped to retrieve contaminants.  Pretreatment and multi-
media filtration are used to remove metals. Volatile organic compounds are removed through air
stripping and activated carbon. The  treated groundwater, which will meet Federal and State
primary drinking water standards, will be returned to the aquifer through irrigation/infiltration
piping or spraying upgradient of the sites. The number of wells and pumping rate would be
determined through groundwater modeling during the design phase of the remedial action
implementation.  This alternative will halt the continued migration of the contaminated plume
and enhance groundwater quality.

ANALYSIS OF ALTERNATIVES

During the detailed evaluation of remedial alternatives, each alternative is assessed against the
nine evaluation criteria which are summarized below.

1.      Overall Protection of Human Health and The Environment draws on the assessments
       conducted under other evaluation criteria and considers how the alternative addresses site
       risks through treatment, engineering, or institutional controls.

2.      Compliance With ARARs evaluates the ability of an alternative to meet Applicable or
       Relevant and Appropriate Requirements (ARARs) established through Federal and State
       statutes and/or provides the basis for invoking a waiver.

3.      Long-Term Effectiveness and Permanence evaluates the ability of an alternative to
       provide long term protection of human health and the environment and the magnitude of
       residual risk posed by untreated wastes or treatment residuals.

4.      Reduction of Toxicity, Mobility or Volume Through Treatment evaluates an
       alternative's ability to reduce risks through treatment technology.
                                                                                  21

-------
 5.     Short-Term Effectiveness addresses the cleanup time frame and any adverse impacts
       posed by the alternative during the construction and implementation phase, .until cleanup
       goals are achieved.

 6.     Implementability is an evaluation of the technical feasibility, administrative feasibility,
       and availability of services and material required to implement the alternative.

 7.     Cost includes an evaluation of capital costs, annual operation and maintenance (O&M)
       costs, and net present worth costs.

 8.     Agency Acceptance indicates the EPA's and the State's response to the alternatives in
       terms of technical and administrative issues and concerns.

 9.     Community Acceptance evaluates the issues and concerns the public may have
       regarding the alternatives.

 The first two criteria, protection of human health and the environment and compliance with
 Applicable or Relevant and Appropriate Requirements (ARARs) are considered by the EPA to
 be threshold criteria which each alternative must meet.  The next five are balancing criteria, and
 the final two are considered modifying criteria.

 ANALYSIS OF ALTERNATIVES

 Overall Protection of Human Health and Environment
 Groundwater use restrictions in place in Area K are protective of human health. Accelerating
 groundwater cleanup would provide greater protection than relying on these institutional controls
 alone.  Alternatives 4 and 6 would pump and treat water at the greatest rates and may therefore
 be the most protective of human health and the environment.  Alternative 5 would also actively
treat contaminants but at a slower rate. Alternatives 1, 2 and 3 rely on slowly occurring natural
processes to remediate groundwater.  However,  groundwater monitoring under Alternatives 2
 and 3 are more protective than Alternative 1 since changes in contaminant levels and migration
 are monitored.

Compliance with ARARs
 EPA considers drinking water Maximum Contaminant Levels (MCLs) and because of the
 location of NAES within the Pinelands, State Practical Quantification Levels (PQLs), whichever
 is more stringent for each contaminant of concern, to be ARARs. All alternatives would require
 an institutional control in the form of a Classification Exception Area since no alternative would
meet ARARs immediately. Alternatives 4 and 6 would reduce contaminant levels the fastest, but
 may require an air permit.  Alternative 5 would reduce contaminant levels at a rate slower than
Alternatives 4 and 6 due to the limited possible in-well circulation rates. Alternatives 1, 2, and 3
would comply with cleanup requirements in the same time frame.
                                                                                    22

-------
 Long-Term Effectiveness and Permanence
 Alternative 4 (Spray Irrigation) and Alternative 6 (Groundwater Pumping and Treatment) would
 provide the greatest overall protection of human health and the environment through treatment of
 high contaminant areas. Alternative 5, in-well aeration, would provide source reduction but at a
 much slower rate (circulation rates of groundwater are 3-4 gpm). Alternatives  1 (no action), 2
 (groundwater monitoring) and 3 (natural restoration) do not actively treat the groundwater and
 therefore provide the same rate of cleanup. However, monitoring of the plume under
 Alternatives 2 and 3 provide  for protection of human health and the environment in terms of
 being able to implement treatment if needed.

 Reduction of Toxicity, Mobility or Volume through Treatment
 Both Alternatives 4 and 6 could provide the highest reduction of toxicity, mobility and volume of
 the plurne depending on designed groundwater pumping rates and system capacities.  The spray
 irrigation of Alternative 4 will only operate in during the six warm months of the year, which
 will reduce its effectiveness.  Alternative 5 would provide some source reduction but at a much
 slower rate than Alternatives 4 and 6.  Alternatives 2 and 3 do not actively reduce toxicity,
 mobility or volume of the plume but would gather important information regarding these
 properties. Alternative 1 offers the least information about the existing contamination and would
 not provide reduction of toxicity, mobility or volume of contaminants.

 Short-Term Effectiveness
 Alternatives 4 and 5 provide the best source reduction with the least construction impacts to the
 environment. Alternatives 1, 2, and 3 require little if any construction activities but require
 longer remediation time. Alternative 6 would require the most disturbance to the area and would
 alter the natural groundwater chemistry through metal removal and pH adjustment.

 I mplementability
 Alternative 1 is the most easily implementable since it requires no further action. Alternative 2.
 groundwater monitoring is currently implemented. Alternative 3 would require an intensive
 study of groundwater and soil conditions but the study could be completed in 2 years.
 Alternative 4, spray irrigation, would be simple to design but may require a prove-out test for air
 permit conditions. Alternative 5 would require special well drilling techniques and may not be
 suitable in the iron-rich environment of NAES. Alternative 6, construction of a pump and treat
 facility, would require the most construction and operations and maintenance effort.

 Cost
 Alternative 1 (no action) has zero cost.  Based on contaminant transport models, a low cost
 source reduction technique may be more cost effective than long term monitoring alone. The
cost of a natural restoration study may not be justified since long term monitoring alone will
produce the same result. Groundwater pump and treat is the most costly alternative due to the
extensive construction and operations and maintenance required of the system.

Agency and Community Acceptance
Agency and Community Acceptance will be addressed in the Responsiveness Summary to the
Record of Decision.

                                                                                    23

-------
THE SELECTED ALTERNATIVE

To address low levels of volatile organic compounds (VOCs) in groundwater in Area K, the
selected alternative is Alternative 4, limited pumping of groundwater to reduce higher levels
through sprinkler irrigation and monitor contaminants through sampling and analyses. Existing
groundwater use restrictions will continue until levels of contaminants in groundwater are in
compliance with applicable groundwater standards. Sampling will be conducted using the
existing network of 24 monitoring wells in the area and groundwater will be analyzed semi-
annually for volatile organic constituents. A sprinkler irrigation system will be installed between
Test Tracks 2 and 3 to pump and aerate the groundwater containing the highest levels of
contaminants.  This system will consist of sprayers and an infiltration basin to aid the percolation
of water back to the aquifer. Spraying will only occur in temperate months of the year to prevent
freezing and aid in the volatilization of contaminants.  It is anticipated that an air permit will not
be required due to the low levels of contaminants present. However, the Navy will submit
information to the NJDEP AirjQuality Permitting Program for their determination and the permit
process will be initiated if necessary. Groundwater will be returned to the aquifer to prevent
depletion. The alternative will include the establishment of a Classification Exception Area
(CEA) pursuant to NJAC 7:9-6.6.
The groundwater would continue to be monitored. The spray irrigation system can be designed
and constructed within one year. A workplan detailing the monitoring and spray irrigation
system will be submitted to the EPA and NJDEP within 21 days of the signing of the final
Record of Decision.

STATUTORY DETERMINATIONS

Under CERCLA, the alternative selected must protect both human health-and the environment,
be cost effective and comply with statutory requirements. Permanent solutions to contamination
problems are to be achieved whenever possible.

Based on the consideration of alternatives, Alternative 4 was selected as the preferred alternative
to address the groundwater in Area K for the following reasons:

        • The selected alternative will provide protection of human health and the environment
        through accelerated groundwater cleanup. A combination of spray irrigation, extensive
        monitoring and groundwater use restrictions will be used to ensure protection of human
        health.
        • Spray irrigation will provide a high reduction of toxicity, mobility and volume of the
        plume and is relatively simple to design and implement.
        • The selected alternative is cost effective.
                                                                                    24

process and provides answers to any comments raised during the public comment period.

The responsiveness summary for Area K is divided into the following sections:

OVERVIEW - This section briefly describes the remedial alternative recommended in the
proposed plan and any impacts on the proposed plan due to public comment.

BACKGROUND ON COMMUNITY INVOLVEMENT - This section describes community
relations activities conducted with respect to the area of concern.

SUMMARY OF MAJOR QUESTIONS AND COMMENTS - This section summarizes verbal
and written comments received during the public meeting and public comment period.

OVERVIEW

Area K is located at the NAES in Ocean County, Lakehurst, New Jersey.  This responsiveness
summary addresses public response to the Proposed Plan, proposing pumping and spray
irrigation to reduce high levels of contamination, extensive monitoring of the groundwater and
continued use of groundwater restriction in  the area.

The Proposed Plan and other supporting information are available for public review at the
information repository located at the Ocean County Library, 101 Washington Street, Toms River.
New Jersey.

BACKGROUND ON COMMUNITY INVOLVEMENT

This section provides a brief history of community participation in the investigation and remedial
planning activities conducted for Area K. Throughout the investigation period, the USEPA and
NJDEP have been reviewing work plans and reports and have been providing comments and
recommendations which are incorporated into the appropriate documents. A Technical  Review
Committee (TRC), consisting of representatives of the Navy, the USEPA, the NJDEP, the Ocean
County Board of Health, the New Jersey Pinelands Commission, other agencies and
communities surrounding  NAES was formed and has been  holding periodic meetings to maintain
open lines of communication and to inform  all parties of current activities.

Prior to public release of site-specific documents, NAES's public relations staff compiled a list of
local public officials who demonstrated or were expected to have an interest in the investigation.
                                                                                25

-------
 Local environmental interest groups were also identified and included on this list.  The list is
 attached as Appendix B to this Record of Decision.

 On December 21 and 22, 1996, a newspaper notification inviting public comment on the
 Proposed Plan appeared in The Ocean County Observer and The Asbury Park Press. The public
 notice summarized the Proposed Plan and the preferred alternative. The announcement also
 identified the time and location of a Public Meeting and specified a public comment period, and
 the address to which written comments could be sent. Public comments were accepted from
 January 7, 1997 to February 7, 1997.  The newspaper notification also identified the Ocean
 County Library as the location of the Information Repository.

 A Public Meeting was held on January 15, 1997, from 6:00 to 8:00 p.m. at the Manchester

 SUMMARY  OF MAJOR QUESTIONS AND COMMENTS

 Written Comments
 During the public comment period from January 7, 1997 through February 7, 1997, no written
 comments, from the public, were received pertaining to Area K.

 On February 4, 1997, the NJDEP submitted additional comments to the Proposed Plan for Area
 K. The Proposed Plan was revised to include these comments. A copy of the final Proposed
 Plan for Area K, dated February 5, 1997, has been placed in the Administrative Record for
NAES located at the Ocean County Library, Toms River, NJ.

 Public Meeting Comments
The only question or comment that was received concerning Area K at the Public Meeting held
on January 15, 1997, was if the groundwater contamination was in the Cohansey Aquifer? The
 Cohansey aquifer underlies all of Lakehurst and is the aquifer which is closest to the surface.
The aquifer extends several hundred feet deep, but the contamination from Area K is contained
within the first twenty feet of the aquifer.

A transcript of the Public Meeting is provided in the Information Repository at the Ocean County
 Library, Toms River NJ.
