Location

The Highway 260 and Main Street WQARF site is located in the city of Cottonwood, Arizona. The site is generally bounded to the north by East Mingus Avenue, to the south by Mongini Lane, to the east by the Verde River and to the west by South 15th Street, South Main Street and Highway 260. The site includes a mixture of public, commercial, and residential land uses.

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

Contaminants of Concern

Tetrachloroethene (PCE) and trichloroethene (TCE) in groundwater

Action Taken

Since 2015, ADEQ has installed monitoring wells and sampled private domestic use wells at the site. During the Remedial Investigation (RI), two source areas have been identified as the “North Area” and “South Area”. Several private domestic wells have been impacted above Aquifer Water Quality Standards (AWQS) for PCE and, in some wells, TCE. ADEQ has installed wellhead treatment systems at these wells as part of Early Response Actions (ERAs) taken at the site. The Remedial Investigation was completed in June 2020 and the report was finalized in May 2021. The Feasibility Study (FS) was completed in March 2022.

Status

The Proposed Remedial Action Plan (PRAP) is in progress and will be made available for public comment upon completion. ERAs and periodic private well sampling activities are ongoing.

From June 2018 to June 2023, implemented wellhead treatment systems have treated an approximate 13,138,923 gallons of water and removed 2.11 pounds of chlorinated volatile organic compounds (CVOCs).
