Health Assessment for Ciba-Geigy Corporation (McIntosh Plant), McIntosh, Washington County, Alabama, Region 4. CERCLIS No. ALD001221902

摘要

The Ciba-Geigy Corporation site is on the National Priorities List. It also is a Resource Conservation and Recovery Act (RCRA) site. The 1,500-acre site is the location of an active facility (disposal operations carried out under the RCRA permitting process) which produces organic chemicals, pesticides, agricultural and synthetic resins. Past disposal practices utilized several on-site landfills and an open burning area. The environmental contamination on-site consists of DDT, lindane, hexachlorobenzene, and benzo(a)pyrene in soil; chlorobenzene, methylene chloride, phenols, and toluene in surface water; and chromium and mercury in sediment. Based on the available information, the site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via groundwater, soil, sediment, surface water, and air.
