Contaminants of concern: Trichloroethene (TCE) and chromium

Action taken: In 2013, the final remedial investigation report was issued and the feasibility study (FS) was initiated.  ADEQ has began addressing RI data gaps. 

A local water provider was operating an ADEQ-funded wellhead treatment system as an early response action to remove TCE from early 2007 to mid-2018. This system has been placed on bypass as concentrations of TCE have fallen below regulatory levels.

By 2018, all RI data gaps were addressed: additional boreholes and wells were installed to aid in delineating the lateral extent of the TCE groundwater plume; a soil vapor extraction (SVE) pilot test was conducted; the shallow soil-gas plume was defined; and indoor air samples were collected where soil-gas results indicated.

In 2019, ADEQ installed a wellhead treatment system on a small water provider’s drinking water well.

Status: ADEQ has issued the final FS report.

Community Advisory Board (CAB): Established 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 >
