Concerned about fire contaminants in your soil? A new expert guide can help

A new guide from a group of local scientists helps Angelenos affected by the 2025 L.A. fires navigate questions about soil testing and clean up.

The guidelines are based on soil tests conducted by USC CLEAN and Community Action Project Los Angeles on more than 6,000 lots in and around burn zones in the Pacific Palisades and Altadena.

Sujeet Rao, the health and well-being practice director at Public Exchange at USC, who contributed to the guide, said it’s a response to questions that he and other contributors knew residents had.

“We all came together … to help fire-affected families understand and navigate questions they may have about environmental contamination related to the fires,” Rao said.
