Palmdale Air Force Plant #42
United States Air Force Plant 42 is a classified United States Government aircraft manufacturing plant, used by the United States Air Force. It is also used by the National Aeronautics and Space Administration (NASA).
Plant 42 and Palmdale Regional Airport (PMD) are separate facilities that share a common runway at the site. The facility is located in the Antelope Valley, approximately 60 miles from downtown Los Angeles.
Site 5 - The Abandoned Fire Training Circle
The fire training circle is located in the central airfield portion of Palmdale Air Force Plant #42 and was used for fire training activities between 1959 and 1981. The abandoned fire training circle is approximately 100 feet in diameter and was initially unpaved with soil berms constructed around the burn area. Former fire training at the site involved spraying flammable liquids (e.g., petroleum, chlorinated solvents, etc.) then igniting and extinguishing the liquids. Large amounts of aqueous film forming foam (AFFF) were used as the extinguishing agent during the fire training exercises beginning in approximately 1970; however, the total amount is unknown.
The area was used for training exercises 24 times per year until 1981, when the activities at Site 5 ceased. An estimated 255,600 to 384,000 gallons of liquids were used, with most of the flammable liquid burned out during training, although some percolated into the soil.

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the California State Water Resources Control Board, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the U.S. EPA (January 2019 - March 2019), tap water provided by this water utility was in compliance with federal health-based drinking water standards.
Legal does not necessarily equal safe. Getting a passing grade from the federal government does not mean the water meets the latest health guidelines.
Legal limits for contaminants in tap water have not been updated in almost 20 years.
The best way to ensure clean tap water is to keep pollution out of source water in the first place.
