East Central Phoenix - 48th Street and Indian School Road | Site Overview

Registry placement date: March 26, 1999

Score: 27

County: Maricopa

Location: Phoenix, bounded by Devonshire Avenue to the north, Fairmont Avenue to the south, 48th Street to the east and 45th Place to the west 

Contaminant of concern: Tetrachloroethene (PCE)

Action taken: ADEQ and the Salt River Project (SRP) entered into an agreement to conduct a source control interim remedial action (IRA) in 2004. As part of the IRA, SRP constructed a soil vapor extraction (SVE) system to remediate the source of PCE in soil. SRP relinquished control of the SVE system to ADEQ which continued to operate and was then decommissioned in 2012. A vapor intrusion indoor air assessment study took place during the summer of 2013 and in February 2014. This assessment focused on residences (specifically single-family homes and ground-floor residences of multi-unit buildings) and schools. Results indicated that there was no threat to residences from vapor intrusion and that no indoor mitigation systems were necessary. 

Status: The Remedial Investigation (RI) is ongoing at the Site. ADEQ is drilling soil borings and installing additional monitoring wells to characterize the vertical and horizontal distribution of the PCE contamination at the Site. The RI Report is anticipated to be complete in mid- to late-2019.

Community Advisory Board (CAB): Established and meets on a regular basis. A list of CAB members and their contact information is available in the Community Involvement Plan (CIP) | View CIP>
