    Stage of Clean-up: Construction Completed

    California Conditions at proposal (January 22, 1987): Southern California Edison Co. (SCE) treated utility poles on a 20-acre site in Visalia, Tulare County, California, from the 1920s until 1980. The site is on the edge of town in a primarily agricultural area with some scattered industry and houses. Wood preservatives, including CREOSOTE and pentachorophenol (PCP), were used and stored on-site during the poleyard's operations. Leaking tanks and stored treated poles have contaminated ground water and soil with wood-treatment chemicals, as well as associated hexa-, hepta-, and octachlorodioxins and FURANS, according to analyses conducted by both the California Regional Water Quality Control Board (CRWQCB) and SCE. California Water Service Co. wells within 3 miles of the site supply drinking water to Visalia's 62,000 residents.  More...
