The $21 million cleanup will be completed in 2019 and will require additional groundwater testing
The U.S. EPA has finalized three orders with Lockheed Martin Corp. and Honeywell Intl. Inc. requiring the companies to expand groundwater treatment and conduct additional groundwater contamination studies at the San Fernando Valley Area 1 Superfund site. The work is expected to cost more than $21 million.
The first order, with Honeywell Intl. Inc., will require the company to construct four extraction wells on the western portion of the North Hollywood Operable Unit (NHOU) site and build a treatment system for 1,4-dioxane, hexavalent chromium and other volatile organic compounds (VOCs) from the area that will prevent additional groundwater contamination. The project will cost about $10 million and will be completed in 2019.
The order with Lockheed Martin Corporation, will require the company to design, construct and operate four extraction wells for the eastern portion of the NHOU that will address VOCs. The system will prevent further migration of existing groundwater contamination. It will be completed around 2020 and will cost approximately $10 million.
Both Lockheed and Honeywell are owner and operators of former aerospace manufacturing facilities which released contaminants including TCE, PCE, hexavalent Chromium, and/or 1,4-dioxane into the groundwater.
