N BOUNDRY OF CITY LIMITS
The Elmendorf Air Force Base (EAFB) site covers approximately 13,130 acres near Anchorage. The Installation is bounded by Knik Arm of Cook Inlet to the west, the municipality of Anchorage to the south, and Fort Richardson Army base (also on the NPL) to the east and north. More than half of the area at the site is undeveloped, including 1,416 acres of wetlands, lakes and ponds. The remaining area has been developed for airfield operations, base-support operations, housing, and recreational facilities. In 2010, Elmendorf Air Force Base and Fort Richardson were merged under the Base Realignment and Closure to become Joint Base Elmendorf-Richardson (JBER). The Air Force has identified 33 parcels for investigation under Superfund. These parcels are grouped into six operable units, including: inactive landfills contaminated with lead, batteries, and waste solvents; inactive underground storage tanks where fuel leaks and spills have occurred since the mid-1950s; a shop-waste disposal area and former transformer area, where solvents, paints, and transformer leaks have contaminated soils with polychlorinated biphenyls (PCBs); ten source areas consisting of hangars and aircraft maintenance facilities, a drum storage area and an inactive fire training area; fuel spill areas; former landfills and surface disposal areas; and pesticide storage and petroleum areas. A 27 Acre site, DP98, was added to the Federal Facility Agreement (FFA) in 2004 to address chlorinated solvents in soils and groundwater. Investigations into Spill Site 22 (SS22) to determine the extent and magnitude of contamination have been underway since 2001. The area was historically used for materials handling and subsurface disposal of waste in pits and trenches, resulting in 28 potential areas of concern. A risk assessment, remedial investigation, and feasibility study are underway to characterize the site. Current construction activities on the Installation may expose areas with buried debris or stained soils, resulting in new investigations for soil or groundwater contamination. EAFB employs about 7,400 people, and approximately 8,600 people currently live on the base. Approximately 121,000 people reside within three miles of the site. Emergency backup water supply wells for EAFB are located within three miles of the identified contamination. Several sensitive environments exist within, adjacent to, or downgradient from the areas of contamination at the base. These include wetlands, moose habitats, beaver ponds, and Ship Creek, which has several active fisheries, including salmon. Site Responsibility: This site is being addressed through state and federal actions under a CERCLA federal facilities agreement.
