Public Health Assessment for Allied Chemical and Ironton Coke, Ironton, LawrenceCounty, Ohio, Region 5. CERCLIS No. OHD043730217

摘要

The Allied Chemical/Ironton Coke site is in the City of Ironton, Lawrence CountyOhio. The areas of concern for this public health assessment are the former Coke Plant and Lagoon Area and the Tar Plant. From 1920 to the 1960's, waste was discharged into the lagoon area. Soil samples showed the on-site surface soil to be contaminated with cyanide, phenolics, benzene, naphthalene, and benzo(a)pyrene (a polynuclear aromatic hydrocarbon). Groundwater analysis detected a number of volatile and semi-volatile organic compounds plus cyanide. Sediment samples from Ice Creek, a stream bordering the lagoon area contained low levels of cyanide, phenolics, and naphthalene. The site poses a public health hazard because of the potential for long-term exposure to cyanide, benzo(a)pyrene, and naphthalene in on-site soils. The Allied Chemical Coke site also poses an indeterminate public health hazard because of the potential impact on a public water supply. The residents who obtain their drinking water from the Coal Grove well field are potentially at risk of exposure to chemicals originating from the site.
