The 18-acre Selma Treating Company site (Site) includes a 3 to 4 acre wood treatment facility and 14 acres of an adjacent vineyard that were used for site drainage. The facilities on-site have been used by a series of owners to treat lumber products almost continuously since 1936. Historically, at least two methods of wood preservation have been used on-site. Before 1965, lumber was dipped into a mixture of pentachlorophenol (PCP) and oil, and then was dried on open racks, letting the excess liquid drip off. In 1965, the Site converted to a pressure-treating process, which consisted of two basic steps: conditioning the wood to reduce moisture content and to increase permeability, and impregnating the wood with chemical preservatives. From 1936 to 1971, chemical wastes from the treatment plant were disposed of on-site in percolation ditches, dry wells, an unlined pond, and a sludge pit. Chemical preservatives also were released to the ground, particularly in the wood treatment area, as a result of spillage, dripping, and leaking. Waste fluids were discharged through pipelines that ran along the boundaries of the vineyard into off-site drainage areas and ditches. In 1971, after the Regional Water Quality Control Board (RWQCB) determined that the discharges posed a serious threat, the Selma Treating Company was required to install an effluent recovery system. In 1981, the Selma Treating Company filed for bankruptcy. In 1982, Sawmill Properties, Inc. acquired the facility with the stipulation that Selma Leasing Company continue to accept responsibility for Site cleanup. The groundwater aquifers beneath the Site provide the only source of potable water in the area. The Town of Selma has a population of approximately 23,000 people.
