The mission of the MCAS Yuma Detention Facility is to provide the Provost Marshal’s Office with the capability to temporary detain individuals suspected of or having actually committed an offense.
Established in 2024, after the disestablishment of the Marine Corps Air Station Yuma Brig, the Assistant Deputy Commandant, Installations and Logistics (Facilities), redesignated the Level I Marine Corps Military Correctional Facility (MCF) aboard MCAS Yuma to a Detention Facility, enabling the Provost Marshals Office to support holding cell and detention space capabilities. Currently, this includes the temporary detention of individuals suspected of or having actually committed an offense.
Marine Corps Air Station Yuma no longer has the capability to confine individuals aboard the installation. Commanders who deem confinement necessary for an individual can contact the MCAS Yuma Detention Facility.

PUBLIC NOTICE OF AVAILABILITY
MARINE CORPS AIR STATION YUMA YUMA, ARIZONA
PROPOSED TIME-CRITICAL REMOVAL ACTION AT MUNITIONS RESPONSE PROGRAM SITE 1A AND
CERCLA AREA OF CONCERN (CAOC) 10 November 2025
The United States Department of the Navy (Navy) announces the public availability of the Action Memorandum to implement a Time-Critical Removal Action (TCRA) within an area of Munitions Response Program (MRP) Site 1a and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Area of Concern (CAOC) 10, located at Marine Corps Air Station (MCAS) Yuma, in Yuma, Arizona. This removal action will involve digging up and safely transporting soil with lead and polycyclic aromatic hydrocarbons (PAHs) above cleanup levels to an approved off-site disposal facility. The Action Memorandum was prepared in coordination with the Arizona Department of Environmental Quality (ADEQ) and the U.S. Environmental Protection Agency (EPA).
The 11.43-acre cleanup area is located in the southeastern part of MCAS Yuma, south of the installation’s main buildings. This area was once used as the Moving Base Range, where aerial gunners trained by firing at moving targets from moving vehicles. Past investigations found lead and five PAHs—benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, dibenzo[a,h] anthracene, and indeno(1,2,3-cd)pyrene—at levels that could pose human health risks.
The Navy will carry out this removal action to ensure that soil left behind is safe. After contaminated soil is removed, samples will be collected to confirm cleanup goals are met and to determine whether the site is safe for unlimited use and unrestricted exposure. Because part of the area may be developed in the future for residential and recreational use, meeting these cleanup goals is especially important.
