Federal officials drop post-fire soil testing in Los Angeles, raising contamination concerns
The U.S. Army Corps of Engineers will not conduct soil testing after clearing debris from Los Angeles County properties burned by recent wildfires, leaving homeowners and local officials concerned about lingering toxic contamination.
Tony Briscoe reports for Los Angeles Times.
In short:
- The Army Corps says removing six inches of topsoil is enough to eliminate hazardous pollution, breaking from a long-standing practice of testing soil after wildfire cleanups.
- Previous fire cleanups, including the 2018 Camp fire, found dangerous levels of contaminants remained even after initial soil removal, prompting additional remediation.
- Without federal testing, homeowners, schools businesses may have to pay for testing and further cleanup to meet California’s safety standards.

“If they’re not willing to do confirmatory sampling, that tells us they’re willing to leave the properties contaminated.”

Why this matters:
Wildfires don’t just destroy homes and landscapes — they can leave behind toxic legacies in the form of contaminated ash and soil. When structures burn, they release heavy metals like lead and arsenic, which can settle into the ground and linger long after the flames have been extinguished. Without proper testing and remediation, these contaminants could remain in residential areas, exposing families to long-term health risks. Children and other vulnerable populations are particularly at risk, as lead exposure can affect brain development and arsenic has been linked to cancer. As wildfires become more frequent and intense, concerns about post-fire contamination are growing, raising questions about how to protect communities from the hidden dangers left behind.
