New LA School Built on Contaminated Site

New school campus devoted to environmental themes
Howard Blume, Los Angeles Times, September 5, 2010

The $75.5-million Carson-Gore Academy of Environmental Sciences opened this September for about 675 students. However, critics say the campus' location poses a long-term health risk to students and staff. School officials scrambled to replace contaminated soil with clean fill, remediate groundwater, install vapor mitigation and air monitoring systems, and put a 45 foot barrier in place between the school and a gas station prior to opening, adding up to a cost of about $4 million.

Construction crews were working at the campus up to the Labor Day weekend, replacing contaminated soil with clean fill. All told, workers removed soil from two 3,800-square-foot areas to a depth of 45 feet, which was impacted from over a dozen underground storage tanks that used to serve light industrial businesses in the area.
The underground tanks of an adjacent gas station may be an additional source. In addition, an oil well operates across the street, but officials said they've found no associated risks. Like many local campuses, this school also sits above an oil field, but no oil field-related methane has been detected. Groundwater about 45 feet below the surface remains contaminated but poses no risk, officials said.
