The San Gabriel Valley site consist of four large areas of ground water contamination located approximately 10-20 miles east of Los Angeles in Los Angeles County, California. The sites include industrial, commercial, residential, and undeveloped areas. The contaminated ground water underlies significant portions of several cities and outlying areas of the San Gabriel Valley, and appears to be the result of inadequate handling and disposal of industrial solvents by dozens of industrial/commercial facilities. This ROD addresses contamination in the Bartolo Well Field, a private water utility, owned and operated by Suburban Water Systems (SWS) and located along the east side of the San Gabriel River in the Whittier Narrows area. The selected remedial action for this site includes: onsite groundwater pump and treatment using an air stripping system equipped with air emissions controls, with subsuquent discharge to the utility's water distribution system; floodproofing the treatment facility; and ground water monitoring.
