Background

The 18-acre Selma Pressure Treating Company Superfund Site (Site) includes a four-acre wood treatment facility and a vineyard next to the Site where liquids from the facility were dumped. The Selma Pressure Treating Company was a wood treatment company that operated from 1936 to 1981 in Selma, Calif. The wood treatment activities contaminated the soil and groundwater with harmful chemicals including hexavalent chromium.

The U.S. Environmental Protection Agency (EPA) added the Site to the Superfund program’s National Priorities List (NPL) in 1983. EPA has been cleaning up the soil and groundwater contamination.
