摘要

The Koppers Wood Treating Company (Koppers) is an abandonded wood treatingfacility north of Carbondale, Illinois, that ceased operations in July 1991. A maintenance worker periodically visits the site to service the on-site wastewater treatment plant but does not remain at the site full time. A fence surrounds the site, and all access roads into the site are secured by locked gates. Soils at the site are visibly contaminated with creosote. Groundwater contaminated at the site includes phenols, metals, volatile organic chemicals, pentachlorophenol (PCP), and polycylic aromatic hydrocarbons (PAHs). Limited removal activities took place at the site in 1991, but much of the contamination remains. Past accidental releases of creosote products have resulted in off-site contamination of Crab Orchard Creek sediment. A public water supply system services most of the homes near the site. Four private residential wells about 0.5 miles north of the site were sampled for site-related contaminants including phenols, PCP, and PAHs. Samples collected in 1989 contained low levels of PAHs in two of the residential wells. In 1992, the Lakeside Water District distribution system was extended to provide water to homes north of Carbondale, including the four homes where private wells were sampled.
