County: Navajo

Location: In the Lakeside portion of Pinetop-Lakeside, generally bounded by John L Fish Lane to the north, Burke Lane to the south, the western boundary of the Blue Ridge Unified School District property to the east, and Niels Hansen Lane to the west.

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)

Action taken: During groundwater sampling in 2015, PCE and TCE were detected in private wells on properties near the intersection. PCE was detected at concentrations ranging from 47 to 59 parts per billion (ppb) in private wells used to supply drinking water and irrigation. The Arizona Aquifer Water Quality Standard (AWQS) for PCE and TCE is 5.0 ppb. TCE has not been detected above the AWQS. ADEQ has worked with affected wells owners to ensure access to safe drinking water. ADEQ has completed a Remedial Investigation (RI), Feasibility Study (FS), Proposed Remedial Action Plan (PRAP) and Record of Decisions (ROD) for the Site.

Status: During fall 2022, a pilot test for Soil Vapor Extraction was conducted at the source property. Results from the pilot test are still being analyzed. The site is currently undergoing remediation by Monitored Natural Attenuation, along with wellhead treatment for affected water systems. Groundwater continues to be sampled, sitewide, twice per year.

Community Involvement Activities: A community advisory board (CAB) was formed in fall of 2016 and meets on a regular basis. A list of CAB members and their contact information is available in the Community Involvement Plan (CIP) | View CIP >
