Superfund Record of Decision (EPA Region 9): North Hollywood/Burbank Well Field Area 1, San Fernando Valley Site, California (First Remedial Action), September 1987

摘要

The North Hollywood - Burbank Well Field (NHBWF) is located within the San Fernando Valley Ground Water basin, which can provide drinking water for approximately 500,000 people residing in the San Fernando Valley and Los Angeles. In 1980 TCE and PCE were discovered in 25 percent of DWP's wells. In July 1981 DWP and the Southern California Association of Governments began a two-year study funded by EPA. The study revealed the occurrence of ground water contamination plume patterns that are spreading toward the southeast. The primary contaminant of concern to the ground water is TCE with PCE and other VOCs present. The selected remedial action for the site is ground water pump and treatment using aeration and granular activated carbon - air filtering units, with discharge to the DWP Pumping Station for chlorination and distribution. Spent carbon will be removed and replaced with fresh carbon, with the spent carbon scheduled either for disposal or regeneration. The estimated capital cost for this remedial action is $2,192,895 with present worth O&M of $2,284,105.
