Public Health Assessment for Chem-Central, Grand Rapids, Kent County, Michigan, Region 5. CERCLIS No. MID980477079

摘要

Chem Chentral, a distributor of bulk chemicals, is located in Wyoming, Michigan. Between 1957 and 1962, a fault in the piping at this facility allowed chemicals to leak into the ground. In 1977, the Michigan Department of Natural Resources (MDNR) discovered that a section of ditch 1,000 feet north of the Chem Central property was contaminated with polychlorinated biphenyls (PCBs) and volatile organic chemicals (VOCs). The MDNR traced this contamination to Chem Central, and identified a plume of VOC contamination in the groundwater between the Chem Central property and the ditch. The site poses an indeterminate public health hazard under present conditions because the possibility of exposure to PCBs from the site through the biota of Cole Drain and Plaster Creek has not been fully investigated. The known completed exposure pathway, through surface soil on the site, poses no significant health hazard. Potential exposure pathways include the possible future use of contaminated groundwater.
