Description Fargher Lake Grocery (located near Yacolt) and Shell Mart McKenzie Automotive (located in Morton) are listed on the Washington State Department of Ecology’s Toxics Cleanup Program contaminated sites list; this is because of petroleum releases from leaking underground storage tanks. Both projects underwent some initial cleanup work, however, it has been several years since any cleanup activities have occurred at either site. At the time of the last groundwater monitoring (April 1993 for Fargher Lake Grocery and May 1996 for Shell Mart McKenzie Automotive), contaminant concentrations still exceeded the applicable Model Toxics Control Act (MTCA) Method A cleanup levels. The goal of this project is to collect groundwater samples from the shallow aquifer underlying each site using existing monitoring wells to assess current petroleum contaminant concentrations. This information will assist the Toxics Cleanup Program in determining if further action is needed at either of these sites.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
