The San Gabriel Area I site is affected by one of four contaminated ground water plumes affecting the San Gabriel ground water basin, approximately 40 miles east of Los Angeles. Testing of wells by the California Department of Health Services (DOHS) found areas of the basin contaminated with trichloroethylene (TCE), tetrachloroethylene (PCE), and other chlorinated hydrocarbons. The DOHS has set Action Levels for TCE and PCE at the EPA suggested no adverse response level (SNARL) of 5 ppb and 4 ppb, respectively. The three mutual water companies whose wells have been affected by the contamination serve a population of approximately 200,000. The selected initial remedial measure (IRM) is installation of an air stripping system to treat contaminated ground water from the affected water mutual wells. The capital cost for the project is $525,000 and annual O&M is estimated to be $38,000.
