Technical Report · Thu Nov 15 04:00:00 EST 1990

OSTI ID:5218421

The 40-acre Washington County Landfill site is an inactive sanitary landfill in Lake Elmo, Washington County, Minnesota. Land use in the area is predominantly residential and agricultural. From 1969 to 1975, Washington and Ramsey counties used the site as a sanitary landfill. Monitoring by Washington County in 1981 revealed low level VOC contamination, which poses a health risk based on long-term ingestion of ground water. The ROD addresses a final remedy for drinking water supply as part of a second operable unit. The primary contaminants of concern affecting the ground water are VOCs including benzene, PCE, TCE, and xylenes. The selected remedial action for the site includes providing a municipal drinking water supply system to supply drinking water to 10 homes with private wells that have been affected by the contaminant plume; and continuing operation of the gradient control well and spray-irrigation treatment system for the first operable unit.
