Public Health Assessment for Sauk County Landfill, Excelsior, Sauk County,Wisconsin, Region 5. CERCLIS WID980610141, September 25, 1995

摘要

The Sauk County Landfill site is located in the township of Excelsior innortheast Sauk County. The site is a closed landfill that operated from 1973 to 1983. The landfill was designed to function as a 'natural attenuation' site. This means that the site has no liner, leaving the existing sandy soils and sandstone bedrock beneath the site to filter out any contamination leaching from the site. The site currently poses no apparent public health hazard. There are currently no exposures to contaminants from the site that are expected to result in adverse health effects. Groundwater contamination at the site may pose a public health hazard in the future, should it migrate from the site at its highest concentrations. Relatively high levels of carcinogenic VOCs have been detected in soil gas samples from soil gas probes located next to the landfill. While this cannot be associated with an exposure to those VOC's, a low possibility exists for those compounds to migrate to the ambient air at concentrations that could pose a health hazard.
