Health Assessment for Oak Grove Sanitary Landfill, Oak Grove Township, Anoka County, Minnesota, Region 5. CERCLIS No. MND980904056.

摘要

The Oak Grove Sanitary Landfill (Oak Grove SLF) is listed by the U.S. Environmental Protection Agency on the National Priorities List. This site is located in Oak Grove Township, in northwest Anoka County, Minnesota. The area surrounding the landfill is sparsely populated. The site began operation in 1967 as an open dump. The results of two Remedial Investigations of the Oak Grove SLF have revealed that subsurface soil, cover soil, leachate, an adjacent wetland's surface water and sediment, and a surficial aquifer have been contaminated to varying degrees with volatile organic, semi-volatile organic, and inorganic chemicals. A deeper aquifer that is used as the source of potable water by nearby residents was found to contain very low concentrations of some organic and inorganic chemicals. However, nearby residential wells that draw groundwater from this deeper aquifer are not contaminated. Based on available information, the Minnesota Department of Health has concluded that the Oak Grove SLF site poses no apparent public health hazard.
