Luke Air Force Base (LAFB) is an active military installation located west of Phoenix. Its primary mission is to provide advanced flight training to fighter pilots. Discharges and waste disposal practices at LAFB resulted in soil and possible groundwater contamination. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 2002.

What Has Been Done to Clean Up the Site?

The site is being addressed through federal actions.

The site participated in the Installation Restoration Program, a specially funded program established by the Department of Defense (DoD) in 1978 to identify, investigate and control the migration of hazardous contaminants at military and other DoD facilities. A Federal Facilities Agreement to conduct the site cleanup was signed in September 1990.

EPA has conducted several five-year reviews of the site’s remedy. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended by site decision documents. The most recent review concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment. Long-term protectiveness of the remedy will be verified by continuing groundwater monitoring. The site’s fourth Five-Year Review will be conducted in 2017. Institutional controls are also in place and are in compliance.

What Is the Current Site Status?

This site was addressed in three stages: initial actions and two long-term remedial phases focused on cleanup of the entire site and soil contamination. The Air Force completed all activities necessary to achieve site cleanup completion at Luke AFB.

After cleanup, EPA took the site off the NPL in 2002.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup.

Soil was contaminated with waste oils and volatile organic compounds (VOCs) resulting from the diverse processes that have taken place at the site. Groundwater was potentially contaminated with waste oils and VOCs. This site has arsenic contamination in soils. Arsenic can cause . . . .
