Formerly Used Defense Sites

Formerly Used Defense Sites

DOD is responsible for the environmental restoration (cleanup) of properties that were formerly owned by, leased to or otherwise possessed by the United States and under the jurisdiction of the Secretary of Defense prior to October 1986.

Location

There are 141 eligible properties within the inventory of Arizona for Formerly Used Defense Sites (FUDS) located throughout Arizona. The U.S. Army Corps of Engineers (USACE) maintains a website with interactive maps | View Map >

Contaminants of Concern

Contaminants found on FUDS sites can vary depending on how the property was used. Contaminants in soil from UST spills include petroleum hydrocarbons and benzene. There is a possibility of contamination from unexploded ordnance (UXO) and from skeet ranges with polyaromatic hydrocarbons (PAHs) and lead.  Contaminants of concern at the site may change as new data become available.

Public Health Impact

Polyaromatic hydrocarbons may pose a risk to human health.   UXO debris may pose an explosive safety hazard. Discovery of UXO should be reported to the local law enforcement authorities and left untouched.

Action Taken

The Military Munitions Response Program (MMRP) is currently working on completing three remedial investigations (RIs) at FUDS designated properties including the Kingman Gunnery Range, Fort Huachuca, and Sahaurita Air Force Range.

The Kingman Gunnery Range site investigation was completed in 2010, and involved sampling primarily for lead from bullets used during WWII training exercises at the small arms ranges, berms, malfunction range and former moving target base. A former skeet range that was developed into a residential community was investigated and sampled for polyaromatic hydrocarbons (PAHs) which was found to be in exceedance of the Arizona soil remediation levels. USACE began a Time Critical Removal Action (TCRA) for the former skeet range area in 2013 to remove the contaminated surface soil from affected residential yards.
