Superfund Record of Decision (EPA Region 7): Kem-Pest Laboratories, MO. (First Remedial Action), September 1989

摘要

The Kem-Pest Laboratories site is a former pesticide manufacturing facility approximately 3 miles northeast of Cape Girardeau, Cape Girardeau County, Missouri. The 6-acre site is in a rural area devoted primarily to agricultural activities. Contamination at the site resulted from the manufacturing of pesticide products from 1965 until 1977. Production activities took place in an onsite concrete block formulation building. Sewage and plant wastes were disposed of in an onsite lagoon which was backfilled with clay in 1981. EPA investigations beginning in 1981 have identified pesticide and volatile and semi-volatile organic contamination in soil, sediment in drainage channels, and in groundwater. This operable unit addresses contaminated soil and sediment. Future operable units will address groundwater and the formulation building. The primary contaminants of concern affecting the soil and sediment are VOCs including xylenes, other organics including organochlorine and pesticides, and metals including arsenic.
