Highway 260 and Main Street | Site Overview

Registry placement date: December 12, 2016

Score: 40 

County: Yavapai

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)

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. A Feasibility Study (FS) is currently underway to determine potential remedial alternatives to clean up groundwater contamination at the Site. Private domestic well sampling is ongoing. 

Status: The Draft RI Report is currently available for public comment until March 11, 2021. The FS Work Plan was noticed on January 17, 2021. The FS will be worked on as the RI Report is finalized.

Community Involvement Activities: A community involvement area has been established and a fact sheet was mailed to those located in and near the area. A community advisory board (CAB) was established summer 2018. 

If you would like more information and/or want to be on the mailing list please contact the community involvement coordinator.
