$75M Northrop Grumman soil contamination class action settlement

Northrop Grumman agreed to a $75 million class action settlement to resolve claims it contaminated soil and groundwater in Canoga Park, California.

The Northrop Grumman settlement benefits current and former owners of single-family homes or townhomes in the Canoga Park and Winnetka areas of California. It covers those who own an eligible property as of Aug. 11, 2026, as well as those who owned their property as of July 1, 2024, but have since sold it.

A map of the settlement area and sub-areas can be found on the settlement website.

According to the class action lawsuit, Northrop Grumman contaminated soil and groundwater in Canoga Park, California, with trichloroethylene (TCE) and perchloroethylene (PCE). The soil contamination by these harmful chemicals allegedly caused property values to decrease and required mitigation measures to be installed in homes.

Northrop Grumman is an aerospace and defense technology company based in Virginia.

Northrop Grumman has not admitted any wrongdoing but agreed to a $75 million class action settlement to resolve the lawsuit allegations.

The deadline for exclusion and objection is Sept. 25, 2026.
