El Toro Marine Corps Air Station
The El Toro Marine Corps Air Station was located near Irvine, California. Before it was decommissioned in 1999, it was the 4,682-acre home of Marine Corps aviation on the West Coast. About 1,300 acres of land originally taken by the air station was converted into the Orange County Great Park, while the rest was re-zoned for residential and commercial development.
18 wells were tested at the old El Toro Marine Corps Air Station and 6 were found to be above the Lifetime Health Advisory (LHA) of 70 ppt. The wells were found to contain 3,826 ppt. of PFOS/PFOA.
Off base, 4 wells were tested and one was above the LHA with 101.5 ppt of the contaminants

El Toro Marine Corps Air Station Superfund Site
The El Toro Marine Corps Air Station covers about 4,700 acres. Commissioned in 1943, it supported the Fleet Marine Forces in the Pacific Ocean, serving as the major west coast jet fighter facility. A total of 25 potentially contaminated areas were identified on the Air Station, including four landfills suspected of containing both hazardous and solid waste, and other areas where polychlorinated biphenyls (PCBs), battery acids, leaded fuels and other hazardous substances were suspected of being dumped or spilled. Site investigations and long-term cleanup activities and monitoring are ongoing.
Two large aircraft hangars were the primary source of the VOC contamination detected in groundwater. This contamination is the principal threat at the site. A second VOC plume in the central area of the station is stable. The four landfills have been inactive for more than 25 years. There are some low levels of contamination, primarily VOCs and metals, in groundwater adjacent to one landfill. However, this contaminant plume appears to be stable and is not migrating. A perchlorate plume emanating from the old explosive ordnance disposal range is present along a tributary drainage to Borrego Wash.
The Upper Newport Bay Ecological Reserve is potentially threatened by contaminants from the site.

33 Total Contaminants
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.
The California Water Board tested the water of the Irvine Ranch Water District in 2019 and found 40.85 ppt of PFOS/PFOA, 29.15 ppt of other PFAS chemicals for a total of 70.0 ppt PFAS 70. See: First round of PFAS sampling for CA Public Water Systems - April 1st to June 30th 2019
