In 2015, Luke AFB investigated facilities where PFAS were potentially used and PFAS containing water was potentially released. The Luke AFB is protective of human health and the environment with respect to the organic solvents and paint strippers, waste oil spills, petroleum spills, metal plating wastes, hydraulic fluids, and radiological wastes. On base groundwater wells are regularly monitored. No on base groundwater wells are known to be impacted by these releases. On base exposure pathways have been eliminated through remediation, restricted access, and restricted use. These contaminant-impacted sites have mitigation remedies in place and do not pose a known risk to human health at this time. Other Luke AFB contaminants include organic solvents and paint strippers, waste oil spills, petroleum spills, metal plating wastes, hydraulic fluids, and radiological wastes. The most significant PFAS human exposure pathway is drinking impacted municipal or well water. Some studies have shown that certain PFAS may increase the risk of cancer, affect the immune system and impact children’s development. PFAS exposure is linked to potential adverse human health outcomes and is the subject of increasing regulation and litigation. Additional groundwater resource information can be found in the sidebar links under SEE MORE. The emerging contaminant continues to be investigated on and offsite at the Luke AFB. The emerging contaminant of PFAS has been detected on and off the Luke AFB in groundwater and soil. Risk mitigation measures have been implemented for known contaminants and locations. There is no current, known, unmitigated risk to human health at this time. Luke AFB impacted media includes groundwater and soil. Potential human health hazards included accidental ingestion or direct contact with contaminated materials. Soil was contaminated with waste oils and volatile organic compounds resulting from the diverse processes that have taken place at the site. Other contaminants associated with Luke AFB include organic solvents and paint strippers, waste oil spills, petroleum spills, metal plating wastes, hydraulic fluids, and radiological wastes. PFAS compounds at Luke AFB are associated (primarily) with firefighting foam (aqueous film forming foam ). PFAS have been used commercially in the United States to make products like stain and water resistant carpet and textiles, food packaging, firefighting foam, as well as in other industrial processes. PFAS are a group of man-made chemicals with fire-retardant properties that have been manufactured and used by a variety of industries since 1940. PFOA and PFOS are members of the per- and polyfluoroalkyl substances (PFAS) family of substances and combined (PFOS + PFOA) make up the PFAS HAL of 70 parts per trillion (ppt). Environmental Protection Agency (EPA) announced a Health Advisory Level (HAL) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Civilian and other military personnel who commute to the base daily from off-base areas bring the total daily base population to approximately 8,000. There are approximately 4,900 military personnel and dependents living on base. The base is approximately located east of Arizona State Route 303, south of Northern Parkway, west of Arizona State Route 101, and north of Camelback Road. The Luke Air Force Base (AFB) site occupies 4,198 acres in Glendale, Arizona, which is approximately 13 miles west of downtown Phoenix.
