Technical Report ·
OSTI ID:5261230

The Southwest Ottawa County Landfill is listed on the National Priorities List. The 43-acre landfill, constructed by the county in 1968 under license by the state, received solvents, heavy metals, paint sludge, oils, municipal refuse, sludge from dewatering lagoons, and drums containing unspecified wastes. Ground water samples indicate that at least 21 contaminants occur or have occurred. Major contaminants with maximum concentrations include: 1,1-dichloroethane (81 ppb), 1,2-dichloroethane (117 ppb), 1,1,1-trichloroethane (8 ppb), benzene (620 ppb), chlorobenzene (950 ppb), ethylbenzene (850 ppb), chloroform (270 ppb), phenol (71 ppb), toluene (170 ppb), xylenes (5000 ppb), trichloroethylene (12 ppb), PCB (Aroclor 1242) (0.53 ppb), lead (70 ppb) and mercury (20 ppb). The Southwest Ottawa County Landfill site is of potential public health concern because of the risk to human health that could result from possible exposure to hazardous substances at levels that may result in adverse health effects over time. Human exposure to chloroform, dichloroethane and trichloroethylene have occurred via ingestion of ground water. Human exposure to toxic chemicals may be occurring via dermal contact, inhalation, and ingestion.
