Deering Avenue Groundwater and Soil Contamination Lawsuit

For decades, industrial operations along the Deering Avenue corridor in Chatsworth and the western San Fernando Valley released hazardous solvents, heavy metals, and degreasing chemicals into the ground beneath surrounding neighborhoods. State and federal investigations have confirmed extensive plumes of trichloroethylene (TCE), perchloroethylene (PCE), 1,4-dioxane, hexavalent chromium, and other volatile organic compounds in the groundwater and soil vapor beneath residential properties, schools, and businesses.

The Source of the Contamination

Manufacturing facilities, aerospace contractors, metal-finishing shops, and automotive operations historically located along Deering Avenue and adjacent industrial parcels disposed of waste solvents through unlined pits, leaking tanks, sumps, and discharges to bare ground. Over decades, these chemicals migrated downward into the aquifer and outward beneath nearby homes, generating soil-vapor intrusion that delivers carcinogens directly into indoor air through cracks in foundations and utility penetrations.

Health Risks of TCE, PCE, and Related Solvents

Trichloroethylene is a known human carcinogen formally classified by the EPA, IARC, and the National Toxicology Program. Documented effects of TCE and PCE exposure include kidney cancer, liver cancer, non-Hodgkin's lymphoma, multiple myeloma, leukemia, cardiac birth defects, neurodevelopmental disorders, autoimmune disease (including scleroderma), Parkinson's disease, and reproductive harm. 1,4-dioxane is a likely human carcinogen with no safe drinking-water threshold, and hexavalent chromium is the same compound made famous by the Hinkley, California, contamination case.

Property Damage and Loss of Value

Properties within the impacted plume have suffered significant diminution in value. Residential transactions now require disclosure of the contamination and often vapor-intrusion mitigation systems. Many homeowners have been forced to install sub-slab depressurization systems, replace HVAC components, and conduct repeated indoor-air testing — all at considerable expense.

Who May Qualify

Current and former residents, employees, and property owners in the impacted area — including portions of Chatsworth, Canoga Park, West Hills, and Winnetka — who have developed qualifying illnesses or whose property values have been impaired may bring claims. Children and long-term residents with the heaviest cumulative exposure are particularly vulnerable.

Damages Available

Recovery may include medical expenses and medical monitoring, diminished property value, the cost of vapor mitigation and remediation, relocation costs, pain and suffering, and punitive damages against polluters whose conduct shows a conscious disregard for community safety.
