7th Street and Arizona Avenue | Site Overview

Registry placement date: April 27, 2000

Score: 40

County: Pima

Location: Downtown Tucson, approximately bounded by Speedway Boulevard to the north, Eighth Street and the railroad to the south, Fourth Avenue to the east and Perry Avenue to the west

Contaminants of concern: Tetrachloroethene (PCE), trichloroethene (TCE) and cis-1,2-dichloroethene (cis-1,2-DCE)

Action taken: ADEQ operated an early response action soil vapor extraction (SVE) system at the former Oliver’s Cleaners (site source) from June 2006 to July 2009 that removed more than 700 pounds of volatile organic compounds (VOCs).

ADEQ issued the final remedial investigation (RI), final feasibility study (FS) and the draft proposed remedial action plan (PRAP) in 2014. In 2015, a second source — the former dry-cleaning facility property at 847 North Stone Avenue — was added to the site.

Status: ADEQ is in the process of re-evaluating the necessity of addressing data gaps at the site and revising the FS to include consideration of the 847 North Stone Avenue source. 

Community Advisory Board (CAB): Established, merged with the Park-Euclid CAB in 2014
