Action Taken

In January 2003, as part of an early response action (ERA), ADEQ completed construction of a groundwater treatment system to remediate and control the migration of contaminated groundwater. The groundwater pump and treat system operated from 2003 to 2018. The system is currently offline.

In June 2004, ADEQ initiated an ERA evaluation of the Maroney’s Drycleaner facility. Based on the results, a soil vapor extraction (SVE) system was installed to address the PCE-contaminated soil beneath the site. The SVE system operated continuously from 2006 to 2017. The SVE system resumed operation in January 2020 and currently operates on an intermittent schedule.

The remedial investigation (RI) was initiated in 2007. A final RI report was completed in December 2014. The feasibility study (FS) was completed in 2015. A proposed remedial action plan (PRAP) was completed in June of 2017.


A record of decision (ROD) is currently being drafted for the site.

Community Advisory Board (CAB)
