Health Assessment for Spiegelberg and Rasmussen Dump National Priorities List (NPL) Sites, Green Oak Township, Livingston County, Michigan, Region 5. CERCLIS No. MID980794481 (Spiegelberg) and CERCLIS No. MID095402210 (Rasmussen)

摘要

The Spiegelberg Site and the Rasmussen Dump Site are two separate National Priorities List Sites which share a common property line. The sites are located in Green Oak Township, Livingston County, in southeastern Michigan, approximately 40 miles west of Detroit. A number of Hazardous Substance List (HSL) contaminants were found in on-site groundwater and surface and subsurface soils, with the highest levels in areas in which wastes were dumped directly onto the ground or those areas in which containerized wastes leaked. Site contaminants include methylene chloride, polychlorinated biphenyls (PCBs), toluene, xylene, arsenic, chromium, and lead. Ingestion and/or dermal contact with groundwater, soil, and contaminated foodchain entities and the inhalation of contaminant vapors or fugitive dusts are the primary pathways of human exposure.
