• immediately surrounding the site does not appear to support abundant wildlife and because the site is surrounded by a fence. The nearest surface water bodies are the Stockton Diverting Canal and the Calaveras River, which are about three fourths of a mile north of the site at their closest points. D. STATE AND LOCAL HEALTH DATA Based on the evaluation performed as part of this interim preliminary health assessment, there are no indications that a non-worker population has been exposed to site-related contaminants at levels of public health concern. In addition, there were no adverse health outcomes of concern identified as part of this evaluation. Therefore, state and local health databases were not searched. COMMUNITY HEALTH CONCERNS The Agency for Toxic Substances and Disease Registry contacted the Remedial Project Manager, EPA, and personnel from the California Department of Health Services (personal communication, Diana Lee, January 1991) and the California Regional Water Quality Control Board with regard to community health concerns. At the time of those inquiries, no community health concerns had been reported. ENVIRONMENTAL CONTAMINATION AND OTHER HAZARDS To identify possible facilities that could contribute to the air, soil, and surface water contamination near the Kearney-KPF site, ATSDR searched the Toxic Release Inventory (TRI) for 1987 and 1988. TRI is a database developed by EPA from reports of chemical releases (to air, water, and soil) from certain industries. TRI did not contain information on toxic chemical releases of site-related contaminants from the Kearney-KPF facility nor from other facilities near the site. A. ON-SITE CONTAMINATION In 1986 and 1987, surface (including sludge) and subsurface soil samples were obtained from Pond 1, Pond 2, and the surface drainage area extending from Pond 1. The samples were analyzed for heavy metals, cyanide, and volatile organic compounds (VOCs) (sludge samples only) . From the data and information reviewed for this preliminary health assessment, it appears that soils from the solvent disposal and drum storage areas were not sampled. The results of analyses of the surface and subsurface samples are shown in Table 1. Sludge and soil samples taken from 0-6 inches are considered surface-soil samples; the others are subsurface-soil samples. Although cyanide was reported to be disposed of at the site, only low levels were reported in the soil samples analyses. Two on-site Kearney-KPF production wells (shallow (80-120 feet) and deep (230 feet) ] and three shallow monitoring wells were sampled to determine the 3
