Phoenix Goodyear Airport Superfund Site Information
Phoenix Goodyear Airport CERCLA (Superfund Site) It is important to clarify that PFAS are not included in the PGA Superfund cleanup efforts.
The Phoenix Goodyear Airport (PGA), which is owned and operated by the City of Phoenix, is a Superfund that was placed on the National Priority List in 1983. The US Environmental Protection Agency (EPA) determined two distinct sources that have impacted area soil and groundwater and has designated two Superfund work areas: PGA-North and PGA-South.
Historical operations at the site including aircraft maintenance and military manufacturing activities contaminated the area with solvents and chromium. The contaminants of concern include:
Site cleanup includes treating groundwater, extracting soil vapor, and removing and capping the contaminated soil.
Soil clean up is complete at both PGA-North and PGA-South. The site utilized soil vapor extraction for soil clean up and surface soil was either excavated or stabilized in place to minimize exposure.
The PGA-North groundwater cleanup remedy includes five groundwater pump and treat systems returning cleaned water using a combination of reinjection, infiltration and irrigation.
The PGA-South groundwater cleanup remedy includes two groundwater pump and treat systems and returning cleaned water with beneficial reuse or permitted discharge to a water conveyance feature.
The 2020 Five-Year Review concluded that the remedies at PGA-North and PGA-South are protective of human health and the environment. Treatment of contaminated soils prevented further migration of contaminants from the soil to groundwater. The groundwater treatments systems eliminate migration of contaminated groundwater and are restoring water quality in the aquifer.
EPA and ADEQ (Arizona Department of Environmental Quality) continue to monitor City of Goodyear production wells to ensure the public is protected from exposure to contaminated groundwater.
