El Toro Marine Corps Air Station (MCAS)

Base Background

Location Irvine, California, 92618, United States
Years of Operation 1943-1993

The El Toro Marine Corps Air Station was first commissioned in 1943 and is located near Irvine, CA. This base was one of the main aviation support facilities on the West Coast. It also served as a base for military service members deployed to Vietnam. Thousands of military personnel and family members lived on the base until its closing in 1993, making the station an economic hub for the area.

El Toro Marine Base Contamination

The EPA notes 25 potentially contaminated areas across the base: 4 hazardous waste landfills and other sites where toxic materials were either spilled or deliberately disposed of. Contaminants include polychlorinated biphenyls (PCBs), battery acids, leaded fuels, arsenic, etc. Environmental investigations, remediation work, and monitoring of these sites continue today.

The toxic exposure at the El Toro Marine Corps Air Station in Irvine has left a lasting impact on the health of service members stationed there. Veterans who served at El Toro have developed chronic health conditions, potentially linked to exposure to PCBs, TCE and other chemicals. The contamination’s effects extends beyond the service members themselves, impacting their families and children who lived on or near the base.

If you developed a medical condition related to toxic exposure after living or working at or near MCAS El Toro, our California disability lawyers may be able to help you get compensation. Get a free case evaluation here to explore your legal options.

MCAS El Toro VA Claims

The U.S. Department of Veterans Affairs recognizes toxic exposure during service as potentially eligible for veterans disability benefits, but it can be difficult to prove service connection for non-presumptive illnesses. If you or a loved one has been diagnosed with a condition potentially related to toxic exposure from being stationed at El Toro MCAS (please note the illness list above may be incomplete), get in touch for a free evaluation of your case.
