According to the public health department, the soil in the Palisades Fire burn zone came back clean with no significant findings above safety thresholds.
For the Eaton Fire burn zone, however, ten areas tested positive for lead.
"The identification of high frequency lead exceedances in soil samples from intact parcels downwind of the Eaton Fire is consistent with reports of elevated lead in air samples collected in the days immediately following the fire," read a press release from the health department. "The source of lead in the fire is reasonably expected to be from the burning of homes with lead-based paint, which was common prior to 1979."
The University of Southern California Lusk Center for Real Estate reported that more than 70% of the houses within the Eaton Fire burn zone were built before 1979.
The county said residents with any concerns about their property may want to test their soil or consult an environmental professional about evaluating their property.
