56th Street and Earll Drive

Registry placement date: June 2, 2004

Score: 40

County: Maricopa

Location: Phoenix, bounded by Earll Drive to the north, Roosevelt Street to the south, 56th Street to the east and 26th Street to the west 

Contaminant of concern: Trichloroethene (TCE) and tetracholoroethene (PCE)

Action taken: ADEQ is working cooperatively with a party potentially responsible for the contamination to remediate the site. A pump and treat groundwater system was constructed and started operation in November 2013 as part of an early response action (ERA). 

Status: ADEQ and Freescale Semiconductor have finalized an agreement for Freescale Semiconductor  to continue to operate and maintain the groundwater pump-and-treat system as the ERA to address the TCE and PCE in the groundwater. Groundwater is extracted and treated then discharged into the Grand Canal system for non-potable beneficial reuse as irrigation water under an agreement with Salt River Project. ADEQ and Freescale Semiconductor have finalized a Consent Order for Freescale Semiconductor to perform the remedial investigation and feasibility study for the site.

Community Advisory Board (CAB): Established and meets on a regular basis
