| Abstract |
The 0.94-acre Yakima Plating site is an inactive nickel-chrome automobile bumper replating facility in Yakima, Yakima County, Washington. Ground water from the shallow alluvium aquifer supplies much of the domestic and irrigation water in the Yakima Basin, and many residences adjacent to the site utilize private ground water wells for their water supply. The tanks were used during the electroplating operation cleaning, plating, and rinsing processes. The wastewater system operated from 1965 until plating operations ceased in 1990. Site assessments and investigations conducted by EPA contractors in 1984 and 1990 determined that the sludge and effluent from the settling tank were a dangerous waste under State regulations and that the potential exists for public exposure to metals from contact with contaminated surface and subsurface soil. The Record of Decision (ROD) addresses remediation of contaminated onsite soil, debris, and sludge. The primary contaminants of concern affecting the soil, debris, and sludge are organics including pesticides; and metals including arsenic, chromium, copper, lead, and nickel. The selected remedial action for the site is included. |
