| Abstract |
The 15-acre Arkwood site is a former wood treatment facility in Boone County, Arkansas. Land use in the vicinity of the site is primarily agricultural and light industrial. Ground water on, or near the site is highly susceptible to contamination as a result of underground cavities, enlarged fractures and conduits which hinder monitoring and pumping. State investigations conducted during the 1980s documented PCP and creosote contamination in surface water, soil, debris, and buildings throughout the site. Contaminated surface features at the site include the wood treatment facility, a sinkhole area contaminated with oily waste, a ditch area, a wood storage area, and an ash pile. In 1987, EPA ordered the site owner to perform an immediate removal action, which included implementing site access including fencing and sign postings. The Record of Decision (ROD) addresses remediation of all affected media, and provides the final remedy for the site. The primary contaminants of concern affecting the soil, sludge, debris, ground water and surface water are organics including pentachlorophenol (PCP), PAHs, and dioxin; and oils. |
