The U.S. Environmental Protection Agency on Wednesday said it reached settlements with five companies that agreed to pay more than $3 million to help clean up contaminated groundwater at Superfund sites in the San Fernando Valley.

Lockheed Martin Corp. and Honeywell International will pay $2.2 million toward design work on an expanded cleanup system to treat contaminated groundwater in the North Hollywood area. Lockheed, Goodrich Corp., ITT Corp. and PRC DeSoto will pay $1 million to help the EPA to investigate chromium contamination in groundwater in Glendale. They also will make a $750,000 partial settlement of their share of the agency’s past costs.

“These settlements highlight our priority at EPA to clean up vital drinking water sources,” said Jane Diamond, director of the Superfund division in EPA’s Pacific Southwest regional office, in a statement. “In addition to cleaning up groundwater for use as drinking water, we are making sure those responsible for the contamination pay their fair share of the cleanup costs.”

Last April, the EPA reached settlements with 12 companies, which agreed to pay a cumulative $3.9 million to help fund cleanup of a 190-acre landfill in Monterey Park in the San Gabriel Valley.
