Site Description Previous Investigations Current Status
Site 1 - 
Old Incinerator Ash Disposal Area
Classified documents and small quantities of paint and film wastes were incinerated and disposed of in this area. Metals from paint and film wastes were potential sources of contamination to soil and groundwater. The site is divided into two areas: a 5,000-square-feet area at the base of the Old Incinerator, which is mostly covered by pavement; and an 8,000-square-feet area to the east of the Old Incinerator, which is covered with fill and is partially revegetated. IAS; Remedial Investigation/Risk Assessment (RI/RA); Record of Decision (ROD) No Further Action
Site 2 -
Components Laboratory Fuel Tank
20,000-gallon underground storage tank (UST) supplied fuel for boilers from 1953 to 1982. After leaking 200 gallons of No. 6 fuel oil to the surrounding soil, the UST was drained, cleaned, and abandoned in place. The UST was later removed along with 50 to 75 cubic yards of oil-contaminated soil. IAS; RI/RA; ROD No Further Action
Site 3 -
Chlorinated Solvent Groundwater Plume, Northern Plume
Chlorinated volatile organic compounds (VOCs) were detected in groundwater at the northern portion of NWIRP Bedford near the Facility Storage Building and the Components Laboratory. There was one documented release of 1,1,1-trichloroethane in the loading dock area. The chlorinated VOC plume extends northwest toward an off-property wetland area. Land Use Controls (LUCs) are implemented. RI/RA; Feasibility Study (FS); ROD LUCs are implemented; Semiannual Groundwater Monitoring; Remedial Action in Process
Site 3 -
Chlorinated Solvent Groundwater Plume, Southern Plume (Southern Flight Test Area)

Chlorinated VOCs were detected in groundwater in the southern portion of NWIRP Bedford within the Southern Flight Test Area (SFTA). The source of groundwater contamination has not been determined; however, the source is not likely to the north.

The SFTA property was incorporated into the Site 3 remedial action in 2014. However, the SFTA site is completely unrelated to Site 3 and is handled as a separate site even though it is referred to as Site 3.

RI/RA; FS; ROD LUCs are implemented; Semiannual Groundwater Monitoring; Remedial Action in Process
Site 4 - 
Benzene, Toluene, Ethylbenzene, and Xylene Plume
The benzene, toluene, ethylbenzene, and xylene (BTEX) plume is associated with releases from the former Transportation Building and its 7,600-gallon UST. Investigations identified the BTEX plume in groundwater that has migrated to the north of NWIRP Bedford, to an off-property wetland area. Most of the Site 4 plume is comingled with the Site 3 plume. IAS; RI/RA; FS; ROD LUCs are implemented; Quarterly Groundwater Monitoring
