(AP) – Federal environmental regulators say they have reached a deal with four companies to build a groundwater treatment system at two Superfund sites in southern Los Angeles County.
The Environmental Protection Agency said Tuesday the $14 million settlement is the first step in cleaning up contaminated groundwater at the Montrose and Del Amo Superfund sites in Torrance.
For three decades, the Montrose site made the chemical DDT. The nearby Del Amo site made synthetic rubber. The EPA said groundwater contamination from both sites has mixed and will be treated by the proposed plant.
The settlement is subject to a final court approval. Construction is expected to take 18 months. Once built, it will treat about a million gallons of contaminated water a day.
