Health Assessment for Ionia City Landfill, Ionia, Michigan, Region 5. CERCLIS No. MID980794416

摘要

The Ionia City Landfill (ICL) is listed on the National Priorities List. The 20-acre site is a former landfill located in Ionia City (Ionia County), Michigan. Waste drums containing industrial and non-industrial waste materials were discovered at the site in 1981. Preliminary on-site groundwater sampling results have identified unspeciated chromium (186 ppb), vinyl chloride (86 ppb), 1,1,-dichloroethane (26 ppb), and trans-1,2-dichloroethylene (31 ppb). Surface water sampling results identified vinyl chloride (ND to 23 ppb). Soil sampling results identified chromium, barium, and lead; soil sampling concentrations were not reported. In addition, various organics and inorganics were reported to exist in on-site surface water and sediment. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of human exposure to hazardous substances. Potential human exposures to contaminants include ingestion and direct contact with groundwater, surface water, soil, and possible ingestion of bioaccumulated contaminants in the food chain. In addition, inhalation of volatilized contaminants or contaminants entrained in air is another potential source for human exposure.
