摘要

The Michigan Disposal Service (Cork St. Landfill), which has been proposed for listing on the National Priorities List, is a partially restricted, 68-acre landfill located in an industrialized area in Kalamazoo, Michigan. From 1925-1968 it existed as an unrestricted disposal area. In 1968, it became a Type III facility which accepted only demolition materials. Prior to April 1985, 18 of 41 groundwater samples analyzed had detectable levels of lead with a maximum level of 280 ppb. Lead has been nondetectable in all samples analyzed from wells since April 1985. Arsenic has equaled or exceeded U.S. EPA Drinking Water Standards in 10 out of 148 samples taken since 1981. Volatile organic compounds have been detected, with benzene concentrations ranging from 38 to 1,200 ppb and chlorobenzene concentrations ranging from 14 to 110 ppb. Other contaminants include 1,1,1-trichloroethane (1.0-5.8 ppb), ethylbenzene (2.5-78 ppb), toluene (
