Two hazardous waste sites in Los Angeles County have been added to the Environmental Protection Agency's Superfund cleanup list.
The EPA says groundwater and soil samples from the newly listed locales indicate high levels of trichloroethylene (TCE), a metal-cleaning solvent, at Southern Avenue Industrial Area and the Jervis B. Webb Co., both situated in South Gate.
Wells near the sites that supply drinking water are not currently contaminated, according to the EPA statement, but a possibility for future contamination exists, they say.
Peterson explains why Superfund matters, and why it's funding is not so super, noting that putting a site on a list is not the same thing as cleaning it up.
Of the 1,664 sites listed on the Superfund National Priorities List, only 359 have been cleaned up since 1983, she reports.
