Los Angeles-area wildfires left lead in soil, but how much and where remains contentious
An EPA study indicates that most properties affected by the Eaton Fire have lead levels below hazardous thresholds. However, some scientists express skepticism about the adequacy of the testing methods used. Concerns remain among residents regarding potential contamination and the thoroughness of the cleanup process.
- ▪The EPA tested soil from about 1% of the homes burned in the Eaton Fire and found that most properties do not have hazardous lead levels.
- ▪Only five out of 100 tested lots exceeded EPA screening standards for lead, while seventeen exceeded California's stricter standards.
- ▪Concerns persist among residents due to the lack of soil testing before and after the cleanup, leading to uncertainty about contamination risks.
