"The U.S. Environmental Protection Agency has ordered a new round of air quality tests for a South Bay neighborhood after detecting a variety of contaminants inside homes near two federal cleanup sites.

The EPA sampled 107 homes near the Del Amo and Montrose Superfund sites earlier this year under pressure from residents worried they are breathing dangerous chemicals seeping in their homes from a plume of tainted groundwater below.

The tests detected pollutants associated with the cleanup sites, including benzene, chloroform and trichloroethylene, at levels above the agency's health standards for long-term exposure."
