Technical Report ·
OSTI ID:5122823

The Southern Pacific Transportation Company site is on the National Priorities List. The 640-acre site, a train and locomotive service facility, is located in Roseville (Placer County), California. Preliminary on-site ground water sampling results have identified various volatile organic compounds (VOCs). They include: 1,1-dichloroethane (7 ppm), trans-1,2-dichloroethene (7 ppm), methylene chloride (69 ppm), tetrachloroethene (2.5 ppm), toluene (68 ppb), 1,1,1-trichloroethane (940 ppb), trichloroethene (490 ppb), vinyl chloride (41 ppb). Nickel and zinc were also identified in on-site ground water at concentrations of 30 and 52 ppb, respectively. 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. Direct contact with and ingestion of contaminated soil and ground water by area residents are the exposure pathways of concern.
