Health Assessment for Mosley Road Sanitary Landfill, Oklahoma City, Oklahoma County, Oklahoma, Region 6. CERCLIS No. OKD980620868

摘要

The Mosley Road Sanitary Landfill, an Update 7 site proposed for the National Priorities List, is located 3.3 miles east of Oklahoma City, Oklahoma County, Oklahoma. The 72-acre unlined landfill was operated as an above-ground sanitary landfill between the early 1970's and late 1976. In 1976, an estimated 1.4 million gallons of hazardous wastes were dumped into the landfill's two unlined on-site pits. In 1987, the landfill was closed. Analysis of samples collected before the landfill was closed revealed lead, methylene chloride, trichloroethene, and vinyl chloride in soil, groundwater, and surface water. Under current site conditions the major pathways for human exposure to site contaminants include the ingestion and other domestic uses of contaminated groundwater. Other potential pathways of human exposure to site contaminants include ingestion of and dermal contact with contaminated surface water and soil and inhalation of methane gas, which could be generated by decomposing landfill wastes. The site is determined to be of potential health concern based on the presence of groundwater contaminants and possible human exposure.
