If you own a private well, live in or near the site boundaries, and have not had your well tested, please contact ADEQ.

Contaminant of concern: Tetrachloroethene (PCE)

Action taken: The remedial investigation (RI) began in 2007. Numerous groundwater monitoring and soil vapor wells have been installed at the site. PCE has been detected in groundwater monitoring wells at concentrations as high as 12,900 micrograms per liter (μg/L).

At the Viking Cleaners source area, an air sparge/soil vapor extraction (AS/SVE) system was first installed in 2004 as part of an Early Response Action (ERA). ERA operations were conducted at the site until 2018. It is estimated that the systems removed more than 3000 lbs of volatile organic compounds (VOCs). At the Maroney’s source area, an SVE system was first installed in 2011. The system has been expanded twice and it has removed approximately 115 lbs of VOCs. Rebound evaluations continue at Maroney’s to determine the need for continued operation.

In April 2019, the highest PCE concentration detected in groundwater was 280 μg/L. The remedial investigation report was completed in June 2019 and the Feasibility Study report was completed in September 2019.

Status: The Proposed Remedial Action Plan is currently being prepared.
