The Camp Pendleton Marine Corps Base site covers 125,000 acres in San Diego County, California. The base provides housing, training, logistical and administrative support for the Fleet Marine Force units. Past disposal practices have contaminated the groundwater and soil. In an initial investigation, the Marine Corps found nine areas of contamination. Waste generation operations at this site include maintenance and repair of vehicles (trucks, tanks, and aircraft); landfill operations; waste disposal areas, such as scrap yards; and fire fighting drill areas. The base contains wetlands, streams, and rivers which feed into the Pacific Ocean. This land is the only remaining undeveloped area between Los Angeles and San Diego.
The primary mission of the 4,198-acre Luke Air Force Base (LAFB) site was to provide advanced flight training to fighter pilots. Discharges and waste disposal practices at LAFB resulted in soil and possible groundwater contamination. Thirty-two areas of the base were subject to further investigation. Soil was contaminated with waste oils and volatile organic compounds (VOCs) resulting from the diverse processes that have taken place at the site. Groundwater was potentially contaminated with waste oils and VOCs. Potential human health hazards include accidental ingestion or direct contact with contaminated materials.
This 1,200 acre site is comprised of the Naval Air Station Joint Reserve Base Willow Grove (NASJRB/WG) and the Willow Grove Air Reserve Station (WGARS), which are operating U.S. Navy and U.S. Air Force installations, respectively, located in Montgomery County, Pennsylvania. Activities that generate, store, or dispose of hazardous waste at the facilities fall into four general categories: (1) aircraft maintenance; (2) base civil engineering; (3) fuel operation and (4) personnel training.
