Health assessment for Tosco Corporation, Spokane, Spokane County, Washington, Region 10. CERCLIS No. WAD000641548. Preliminary report

Technical Report ·
OSTI ID:6674729

The Tosco Corporation site was proposed for the National Priorities List in Update 7. The site is located 1.5 miles north of Spokane in eastern Washington. Industrial activities, which have been conducted at the site since the 1920s, have resulted in contamination of environmental media with petroleum-derived chemicals. High concentrations of volatile aromatic compounds and polyaromatic hydrocarbons were detected in on-site soils and groundwater. The migration of contaminated groundwater from the site has impacted off-site private wells, but, to date, there is no evidence that any public water supply wells have been impacted. The use of contaminated water for potable or nonpotable purposes could result in exposures of potential health concern by the ingestion, inhalation, or dermal absorption. Human contact with oil wastes in the former lagoon area could result in exposures of health concern by the ingestion, dermal absorption, or inhalation of contaminants. Such exposures would be most likely to occur during excavations in the lagoon area.
