The former Davisville Naval Construction Battalion Center (NCBC), located 18 miles south of Providence in North Kingstown, covers approximately 900 acres. Serving as a military installation since 1942, its primary mission was to provide mobilization support to Naval construction forces. Much of the NCBC-Davisville site is contiguous with Narragansett Bay and consists of four areas, including the Main Center, the West Davisville storage area, Allen Harbor area, and the Pier Support area. Camp Fogarty, a training facility 4 miles west of the Main Center in the Town of East Greenwich was transferred to the Army in 1993, is also part of the listing. Adjoining NCBC's south boundary is the decommissioned Naval Air Station Quonset Point, which was sold to the Rhode Island Port Authority between 1978 and 1980. The Navy disposed of wastes in all areas. The Navy has identified at least 24 areas with potential hazardous contamination, but the Department no longer owns several of them. These areas are being investigated by the Army Corps of Engineers. Chief among the areas are Camp Avenue Landfill and former NIKE Launcher Site. The Navy's studies will focus on twelve areas: the Allen Harbor Landfill (the largest of the areas), which received solvents, paint thinners, degreasers, polychlorinated biphenyls (PCBs) from transformers, sewage sludge, and contaminated fuel oil from 1946 to 1972; the Calf Pasture Point, which received "decontamination agents" and various other contaminants; the Construction Equipment Department (CED) Battery Acid Disposal Area; the CED Solvent Disposal Area; the Transformer Oil Disposal Area (near Building 37); the Solvent Disposal Area; the Defense Property Disposal Office (DPDO) Film Processing Disposal Area (FPD); the Camp Fogarty Disposal Area; the Fire Fighting Training Area; and the Disposal Areas northwest of Buildings W-3, W-4, T-1; the Asphalt Disposal Area; and the Cresote DipTank and Fire Fighting Area. Approximately twenty 5-gallon cans of calcium hypochlorite were disposed of in a drainage ditch at Calf Pasture Point between 1960 and 1971. In 1973, thirty to forty 35-gallon cardboard containers of a chloride compound were stored at the site and deteriorated over time. From 1968 to 1974, approximately 2,500, 3-gallon cans also were disposed of at Calf Pasture Point. The surrounding area is single-family residential. Groundwater is assumed to flow toward Narragansett Bay, which is located 600 feet from the site. Approximately 27,000 people get their drinking water from public wells located within 3 miles of the site.
Threats and Contaminants
Heavy metals including lead, cadmium, silver, mercury, and chromium were found in the sediments and on the shoreline of Allen Harbor. Other contaminants in Allen Harbor include chlorinated volatile organic compounds (CVOC), polycyclic aromatic hydrocarbons (PAHs), polynuclear aromatic hydrocarbons (PNAs), solvents, and PCBs. Soil contamination is not specified, but dumping practices involved organic solvents, PCBs, sewage sludge, contaminated fuel oil, and halogens. Some public wells are located between 1 and 3 miles upgradient from disposal sites. The potential of contamination to these wells is small. Groundwater is shallow, 2 to 4 feet in some areas, and the soil is permeable, conditions that facilitate movement of contaminants into the groundwater and toward Narragansett Bay. In addition, it has been shown that Allen Harbor is polluted. A number of salt marshes that could be affected by contamination from the site have been identified in the Allen Harbor, Calf Pasture Point, and Narragansett Bay areas.
The site is being addressed in nine stages: initial actions and seven long-term remedial phases focusing on cleanup of Buildings 316 and 38, the Allen Harbor Landfill, the DPDO/FPD and Transformer Oil Disposal Area, Calf Pasture Point, CED Area, the Creosote Dip Tank and Former Fire Fighting Training Area, QDC Outfall 001, and the Main Center Area.
Response Action Status
|Initial Action ||In 1991, the Navy removed materials from two on-site buildings that were|
contaminated by PCB spills. Throughout 1995, the Navy removed PCB-contaminated soil at the disposal areas northwest of Buildings W-3, W-4, and T-1; the battery acid tank at the CED Battery Acid Disposal Area; the asphaltic material at the CED Asphalt disposal area; and lead from contaminated soil at Camp Fogarty.
|Buildings 316 and 38: ||In 1991, the Navy removed flooring materials and underlying soils from Building 316, the DPDO Transformer Oil Spill Area and Building 38, and Transformer Oil Leak Area. Additional sampling after removal operations revealed elevated levels of PCBs outside the excavated areas. A final cleanup remedy was selected in the fall of 1993 calling for the excavation and off-site disposal of remaining PCB-contaminated materials at a federally-licensed disposal facility. Design for the long-term remedy was completed in 1994. Construction activities began in 1995 and were completed in 1997. The excavation was so thorough that the site has been cleaned up to residential values. No longer are institutional controls or 5 year reviews needed. |
|Allen Harbor Landfill: ||In 1985, the water, sediment, and organisms in Allen Harbor were sampled as part of the confirmation studies and found to be contaminated. Given the landfill's location adjacent to the harbor, it is possible that leachate could migrate into the harbor. An investigation into the nature and extent of site contamination and assessment of possible cleanup alternatives was completed by the signing of a capping Record of Decision (ROD) in September 1997. Cap construction began in March 1998. Additional contamination was found after most of the cap was completed so another cap was constructed at the site. Construction of the additional cap was completed in 1999. Over one acre of wetland mitigation was also completed in 1999. Quarterly Long Term Monitoring began in the winter of 2001. The first monitoring event report was submitted in July 2002, and additional reports are being submitted every quarter after this. Institutional controls are in place and being monitored on an annual basis. The next five Year Review is due in 2018 . |
|DPDO/FPD, Transformer Oil Disposal Area and Camp Forgerty: ||The Navy investigated these sites in 1993. An additional investigation into the nature and extent of site contamination and assessment of possible cleanup alternatives was completed in the fall of 1995. From this assessment, the EPA determined that no further cleanup actions were required to address soil at this area of the site. Groundwater was investigated and a final cleanup remedy for No Further Action was selected in June 1998. Additional metals-contaminated soil was removed during 2011 to facilitate construction of a building at Camp Fogarty. |
|Fire Fighting Training Area, Solvent Disposal Area and Disposal Area North West|
of Buildings W-3, W-4, and T-1:
|These areas were investigated in two phases. A removal action excavating and sending off site 2,224 tons of PCB contaminated soils was completed in 1997 at the|
Disposal Area North West of Building W-3, W-4, and T-1. A No Further Action ROD was signed for these areas on September 30, 1998.
|Calf Pasture Point: ||Investigations were performed in three phases, culminating in the signing of a ROD in September 1999 for groundwater monitoring and land use restrictions. Institutional controls have been implemented and are monitored on an annual basis. The mobility of contaminants is moderate to high, however, the effect on the groundwater discharging to the harbor, to date, has been minimal. Long Term Monitoring began in summer of 2001. The first monitoring event report was issued in May 2002. The report recommended installation of additional wells to monitor a newly found lobe of the plume. The second monitoring event took place in the spring of 2002. Well installation was completed in October of 2002. Additional monitoring wells were installed in Summer 2012 to further our understanding of the contamination. These wells were included in the Long Term Monitoring Plan and are sampled either annually, every two years, or every four years. Monitoring events take place every 6 months with data reports submitted within 6 months after the event. Removal of approximately three tons of visually contaminated soil was taken off site during 2011 after Navy uncovered some cans of source are material. Additional monitoring and evaluation is planned for the five year review due in 2018. |
|Construction Engineering Division (CED) Area : ||Investigations into the nature and extent at four areas are scheduled for completion in 2016. These areas include the CED Battery Disposal Area, the CED Solvent Disposal Area, CED Drum Storage Area, and the CED Asphalt Disposal Area. The Navy performed removal actions at the CED Battery Disposal Area and the CED Asphalt Disposal Area in 1996. The Navy removed 197.88 tons of contaminated soil. Groundwater has been found to be contaminated with chlorinated solvents. The Navy's contamination at the CED area is comingling with an off site source area. A ROD is expected to be signed after the Army Corps of Engineers have a regulatory approved remedial action plan to address the off site groundwater source area which is contaminating the Navy's CED area. Institutional controls (IC) have been implemented to ensure no drinking water wells are installed on the site and that the land use is not residential. ICs are monitored on an annual basis. Additional evaluation is planned for the five year review due in 2018. |
|Creosote Dip Tank and Fire Fighting Training Area : ||Field work for investigations into the nature and extent of contamination are complete. Navy found soil contamination in the northern part of the site and a chlorinated solvent plume which migrates across the site from previously transferred land northeast to Allen Harbor and east toward Narragansett Bay. This investigation has determined that there is no unacceptable risk to the commercial/industrial users of the site as long as the soil above state standards is removed, groundwater is not used for drinking water, and buildings are not built above the plume. Institutional controls (no drinking water wells and no residential use) are being monitored on an annual basis. A ROD was signed in 2014. The Remedy is for two feet of contaminated soil removal and two rounds of chemical oxidant injections into the groundwater, and long term monitoring. Additional evaluation is planned for the five year review in 2018. |
|QDC Outfall 001 ||The QDC Outfall 001 study area is currently undeveloped land, with the surrounding area used for recreational purposes, specifically the Quonset Bike Path. Based on a review of historical “as-built” drawings of drainage systems at the former NCBC Davisville, QDC Outfall 001 is the discharge point for an underground drainage pipeline that originates from the former Building 224. The former Building 224 and nearby truck wash pad and oil water separator are the presumed sources of contamination present in the outfall area. The building was used by the Navy as a vehicle maintenance|
and truck-washing facility. Building 224 was demolished by QDC in 2006.
Contaminants associated with materials used in these activities or in other historical activities conducted at the Former Construction Equipment Department (CED) Area may have been disposed/released into the Building 224 drainage system, discharging at QDC Outfall 001. It is believed the primary source of contaminants to the wetland is the vehicle wash pad and oil water separator. Pesticides may also have been used by the Navy to control insects and other pests at the Site. The primary contaminants identified as being associated with the QDC Outfall 001 consisted of petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), pesticides, polychlorinated biphenyls (PCBs), and heavy metals. The RI field investigation was completed in September 2014 and the report is currently under review. A ROD is expected in 2017. Additional evaluation is planned for the five year review in 2018.
|Enforcement Highlights||NCBC is participating in the Installation Restoration Program, a specially funded program established by the Department of Defense (DOD) in 1978 to identify, investigate, and control the migration of hazardous contaminants at military and other DOD facilities. In 1988, the EPA and the Naval Ocean Systems Center began conducting a study at the Allen Harbor Landfill under a Memorandum of Agreement. A Federal Facility Agreement was signed by RIDEM, the Navy, and the EPA in March 1992 to provide the frame work for the cleanup process. The Base was selected for closure under the BRAC Act of 1991 and was officially closed in April 1994. A lease with the Rhode Island Economical Development Corporation (RIEDC), currently known as the Quonset Development Corporation (QDC) was signed at the base for economic redevelopment in 1996. Camp Fogerty was transferred to the Army in 1993. In September 1998, 125 acres were sold to the RIEDC. In October 1998, 96 acres were transferred through a public benefit transfer form the Navy to the US Department of Transportation's Maritime Administration (US DOT-MARAD) to the RIEDC. In April 1999, the West Davisville Parcel (approximately 70 acres) was transferred by Deed from the Navy to RIEDC. In February 2000 the Warehouse Triangle (approximately 250 acres) was sold to RIEDC. Currently, the Navy leases the Construction Engineering Division (CED) Area, the QDC Outfall 001 Area, and the Creosote DipTank/FireFighting Training Area to the QDC. Once the remaining contamination is cleaned up, the Navy will transfer the property via the US DOT-MARAD public benefit transfer. The Navy has transferred Calf Pasture Point and the Allen Harbor Landfill to the Town of North Kingstown for use as open space/passive recreation. |
A remedy was selected in 1993 to address PCB contamination at Buildings 316 and 38. Removal of contamination throughout the site began in 1995 and has reduced contaminant levels in soils. A remedy was selected in 1997 to address the landfill closure at the Allen Harbor Landfill. Cap construction was completed in 1999. A remedy was selected in 1999 to impose land use restrictions and to monitor groundwater contamination at Calf Pasture Point Solvent Disposal Area. Six sites were closed out with No Further Action RODs. Groundwater monitoring started at both the Landfill and the Calf Pasture Point Area in 2001. A remedy was selected in 2014 to remove contamination in soil and groundwater and to impose land use restrictions and monitor groundwater contaminat levels at the Creosote Dip Tank/fire fighting training area . In the meantime, the Navy has performed preliminary investigations and has determined that there are no immediate threats to human health or the environment while additional site studies are taking place.
Current Site Status
NCBC is a closed BRAC 1991 site. Several parcels have been transferred to the RI Economic Development Corporation and the Town of North Kingstown. The site was added to the National Priorities List (NPL) in 1989. In 1991, the Navy removed materials from two on-site buildings that were contaminated by PCB spills. Throughout 1995, the Navy removed PCB-contaminated soil at the disposal areas northwest of Buildings W-3, W-4, and T-1; the battery acid tank at the CED Battery Acid Disposal Area; the asphaltic material at the CED Asphalt disposal area; and lead from contaminated soil at Camp Fogarty. In 1985, the water, sediment, and organisms in Allen Harbor were sampled as part of the confirmation studies and found to be contaminated. Additional investigation into the nature and extent of site contamination and assessment of possible cleanup alternatives was completed by the signing of a capping Record of Decision (ROD) in September 1997. Cap construction began in March 1998. Additional contamination was found after most of the cap was completed so another cap was constructed at the site. Construction of the additional cap was completed in 1999. Over one acre of wetland mitigation was also completed in 1999. The Navy is implementing a long term monitoring plan at the Landfill and the Solvent Disposal Area at Calf Pasture Point.
Investigations into the nature and extent at the Construction Engineering Division (CED) Area are scheduled for completion in 2016 with a plan to clean up the soil. The Navy's groundwater contamination at the CED area is co-mingling with an off site source area, (Former NIKE PR-58 (FUDS)). A Final Groundwater ROD is expected to be signed after the Army Corps of Engineers have a regulatory approved remedial action plan to address the off site groundwater source area which is contaminating the Navy's CED area. Investigations into the nature and extent of contamination at the QDC Outfall 001 Area are continuing with a ROD expected in the year 2017.
