Arizona National Guard Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) Updates

The Air Force launched a comprehensive approach to identify, respond to and prevent drinking water contamination after determining that Aqueous Film Forming Foam — a firefighting agent containing PFOS/PFOA and used commercially and by the Department of Defense — may have been released at fire training areas, emergency response and aircraft crash sites at active, Reserve, Air National Guard and closed installations. Morris Air National Guard Base was one of 203 installations the Air Force Civil Engineer Center identified as a potential AFFF-release location.

As members of the Tucson community, we care about the health of our Airmen and neighbors. We will continue moving forward aggressively in our investigation and work toward remediation. We will remain cooperative with residents and partners to deliver information and updates here as soon as they become available.

Current Environmental Assessments

No information to display at this time



The Federal Aviation Administration announces its adoption of the Final Environmental Assessment (dated December 2019) and issuance of a Finding of No Significant Impact (FONSI) for its federal action of approving an Airport Layout Plan update for the Tucson International Airport (Airport) located in Tucson, Pima County, Arizona. 

The action addressed by the FONSI includes the construction of a new Entry Control Facility (ECF) for the Tucson Air National Guard Base (ANGB) and the relocation of the Aerovation Hangar at the Airport.  The need for this action is driven by the existing configuration of the entry road to the Tucson ANGB, which causes security risks and congestion.

The FONSI indicates that the proposed action is consistent with existing environmental policies and objectives as set forth in the National Environmental Policy Act and will not significantly affect the quality of the human environment.

Electronic copies of the FONSI are available for review at the following:
