Contaminants of Concern

Tetrachloroethene (PCE), trichloroethene (TCE), 1,1,1-trichloroethane (1,1,1-TCA), cis-1,2-dichloroethene (cis-1,2-DCE), 1,1-dichloroethene (1,1-DCE), 1,1,2-Trichloroethane (1,1,2-TCA), 1,2-Dichloroethane (1,2-DCA), vinyl chloride, and chromium

In 2026:

• 1,1-dichloroethane (1,1-DCA) was removed from the Contaminant of Concern (COC) list. It was originally noted in the West Van Buren Remedial Investigation (RI) Report as a COC, however since there is no Arizona Aquifer Water Quality Standard (AWQS), United States Environmental Protection Agency (EPA) Maximum Contaminant Level (MCL), or EPA MCL Goal associated with 1,1-DCA it has been removed.
• Vinyl chloride was added to the COC list. It was detected above AWQS in two groundwater sampling events in 2025 and 2026 and is a potential degradation product of the principal COCs. 

Action Taken

Source removal through soil vapor extraction has taken place at several facilities under Consent Orders or Working Agreements. Other facilities continue to be monitored and/or evaluated through other ADEQ programs (primarily Hazardous Waste), while other facilities have settled their liability with ADEQ. ADEQ finalized the RI Report in August 2012. Two interested parties, under working agreements with ADEQ, submitted separate Feasibility Study Reports in July 2013 and July 2014. Site-wide groundwater sampling events took place in 2019 and 2023. 

Status

ADEQ is currently preparing a Proposed Remedial Action Plan for the site.
