| Abstract |
The 80-acre Dakhue Sanitary Landfill site is an inactive sanitary waste municipal landfill located in Hampton Township, Dakota County, Minnesota. Land use in the area is agricultural and residential. the landfill overlies a sand and gravel surficial aquifer that is not a drinking water source and that extends downgradient of the site. From 1971 to 1988, Dakhue Sanitary Landfill, Inc., owned and operated the landfill and accepted mixed municipal and commercial wastes, and small amounts of industrial waste. State investigations conducted between 1983 and 1989 identified a variety of contaminants onsite. Investigations during the RI/FS identified VOCs, organics, and inorganics in the surficial onsite aquifer, and it has been determined that the possible source of contamination is related to the municipal, industrial, and commercial waste disposed onsite in the landfill. The ROD addresses the source of the contamination as OU1. A future ROD will address ground water contamination and possible remediation of the downgradient plume, as OU2. The primary contaminants of concern affecting the soil and debris are organics including phenols; and metals including arsenic, chromium, and lead. |
