Superfund National Priority List (NPL) Placement: September 1983

Location

The Phoenix-Goodyear Airport (PGA) Superfund site is located primarily in Goodyear, Maricopa County, approximately 17 miles west of Phoenix, in the western part of the Salt River Valley in central Arizona. The US Environmental Protection Agency (EPA) determined two distinct sources that have impacted area soil and groundwater, and has designated the PGA Superfund site as two work areas:

• PGA-North (PGAN) with a source area near a former Unidynamics Phoenix Incorporated (UPI) facility and a mostly northward trending groundwater plume.
• PGA-South (PGAS) with a source area near a former Goodyear Aerospace/Loral facility and multi-aquifer groundwater plumes impacting areas south-southwest and also northwesterly. 

The impacted groundwater plumes are elongated and irregular, but to assist in visualizing the impacted area the site can be roughly framed by Indian School Road on the north, Dysart Road to the east, Broadway Road on the south, and Bullard Avenue to the west. Even though about 11 square miles are framed, the plumes’ irregular footprint area extent is estimated at less than 5 square miles. 

The PGA site lies almost entirely within Goodyear, Arizona. Municipal exceptions include the airport proper, which is owned by the city of Phoenix, and an area near Litchfield Road which is within the city of Avondale. Land use on and near the site includes agriculture, residential, commercial and industrial development | View Map >

Contaminants of Concern (COCs)

Soil | Trichloroethene (TCE), tetrachloroethene (PCE), methyl ethyl ketone (MKE), acetone and metals

Groundwater | TCE, PCE, MKE, acetone, 1,1,1 trichloroethene, 1,1-dichloroethylene, carbon tetrachloride, chloroform, chromium, and arsenic

If you have a private well in the vicinity of the exceedance, we encourage you to test the well water.

Other | Per- and polyfluoroalkyl substances (PFAS)

COCs at the site may change as new data become available.

Action Taken

The PGA-North groundwater cleanup remedy includes five groundwater pump and treat systems (capturing Subunits A, B, and C groundwater), returning cleaned water using a combination of reinjection, infiltration and irrigation.

The PGA-South groundwater cleanup remedy includes two groundwater pump and treat systems (capturing Subunits A and C groundwater) and returning cleaned water with beneficial reuse or permitted discharge to a water conveyance feature (ditch).

Soil clean up is complete at both PGA-South and PGA-North source areas. The site utilized soil vapor extraction for soil clean up.  At PGA-South, select surface and near surface soil was either excavated or stabilized in-place to minimize exposure and exercise chromium source control.
