U.S. EPA ANNOUNCES $49 MILLION NEWMARK SUPERFUND CLEANUP DECISION

 SAN FRANCISCO, Aug. 4 /PRNewswire/ -- The U.S. Environmental Protection Agency (U.S. EPA) today announced a plan for cleaning up a five-mile-long stretch of groundwater contamination at the Newmark Superfund site, San Bernardino, Calif. The groundwater is contaminated by perchloroethylene (PCE) and trichloreothylene (TCE), commonly used as industrial solvents.
 "This action will significantly contribute to the achievement of U.S. EPA's ultimate objective in this project: protection of the health and environment of the citizens who live in the vicinity of this Superfund site," said Jeff Zelikson, U.S. EPA's regional hazardous waste management division director. "This decision was made after careful consideration of all the alternatives and a thorough review of the public's comments."
 The plan calls for extracting contaminated groundwater and treating it to remove volatile organic compounds (VOCs) from the underground water supply at two locations north and east of the Shandin Hills. A groundwater treatment system will be installed at the Newmark wellfield near 48th Street and Little Mountain Drive to prevent further contamination from entering this part of the valley. Groundwater treatment will also be installed at a location near 14th Street between Arrowhead and Waterman Avenues and is designed to stop the spread of contamination to the clean part of the underground water supply or aquifer.
 VOCs will be removed by either of two proven treatment technologies -- carbon filtration or air stripping. As a result of comments from the public concerning the contaminants that are removed from the water, U.S. EPA has also decided to perform a pilot study using an innovative technology called advanced oxidation treatment. The treatment would destroy a large percentage of the contaminants, potentially reducing the overall cost of treatment.
 After treatment, the water will meet all legal requirements for drinking water and will be piped to the public water supply system for distribution or reinjected into the aquifer. The project is expected to be ready by 1996 and is designed to operate for 30 years.
 The Newmark Superfund site includes two plumes of contaminated groundwater. The project originally addressed only the plume east of the Shandin Hills. However, further investigation traced the source of the contamination through a previously undiscovered underground channel flowing from the western or Muscoy side of the valley. In September 1992, the Newmark site was officially expanded to include the Muscoy plume which is being investigated in a separate study.
 Testing by the state of California in the 1980s showed unacceptable concentrations of PCE and TCE in a number of wells in North San Bernardino. The city and Cal-EPA built three water treatment facilities to replace contaminated drinking water supplies and a fourth is under construction. San Bernardino's public water supply is tested to meet state and federal standards.
 The Newmark Superfund site was placed on the National Priorities List (NPL) in 1989. The NPL is U.S. EPA's list of hazardous waste sites potentially posing the greatest long-term threat to public health and the environment. U.S. EPA identifies and ranks NPL sites according to threats to nearby populations through actual or potential contamination of groundwater, surface water or air.
