A $75 million settlement in Los Angeles is offering some relief to homeowners who say toxic chemical contamination damaged both their property values and their peace of mind.
The agreement marks a notable win for residents in Canoga Park and Winnetka who sued major defense contractor Northrop Grumman over alleged soil and groundwater contamination.
Here's what to know
According to Top Class Actions, Northrop Grumman has agreed to set aside $75 million to resolve a class action suit involving eligible current and former owners of single-family homes and townhomes in Canoga Park and Winnetka.
The class action lawsuit had alleged that the defense contractor contaminated thousands of homes after releasing the chemicals trichloroethylene and perchloroethylene into the soil and groundwater. Both of these chemicals have long been linked to health and environmental concerns.
Despite agreeing to pay $75 million to address the contamination, the company maintains that it did nothing wrong, per Top Class Actions. The agreement also provides funding for in-home mitigation aid related to the contamination concerns.
The settlement will provide funds to individuals who are current homeowners (as of August 11, 2026) or to people who have sold their homes since July 1, 2024. A map of the covered area and its sub-areas is available on the settlement website.
