Superfund Site Profile
The Culpeper Wood Preservers site, located in Culpeper County, Virginia, is an active 20-acre wood treatment facility that formerly used the chromated copper arsenate (CCA) waterborne treating process. Early on in the plant's operation, pressure-treated lumber was placed on an uncovered drip pad. As the lumber dried, CCA-contaminated drippings dropped directly to the ground. In early 1981, approximately 100,000 gallons of CCA-contaminated wastewater were released from an unlined, on-site waste impoundment, contaminating neighboring surface waters. In January 1982, the Virginia State Water Control Board (SWCB) determined that the groundwater had become contaminated with arsenic and chromium from the wood treatment processes. The site was formally added to the National Priority List (NPL) on June 10, 1986 making it eligible for federal cleanup funds.
