Final Soil Test Results Unveiled: What Health Officials Discovered in Fire-Ravaged Areas

Altadena has seen a higher number of soil samples with dangerous lead levels than Pacific Palisades following recent brush fires. The Los Angeles County Department of Public Health shared its findings from soil samples taken in these two areas.

In Altadena, 10 out of 23 sampling locations showed lead levels exceeding healthy limits. Experts suggest that the lead likely comes from homes that burned down, many of which had lead-based paint. Notably, over 70% of the homes in Altadena were built before 1979, when lead paint was banned.

In comparison, Pacific Palisades showed no widespread issues related to fire in the soil. An isolated area had some contamination from metals like cadmium and thallium, but it’s unclear if these were linked to the fire.

Soil samples were collected between February 18 and March 26, focusing on harmful substances such as heavy metals and polyaromatic hydrocarbons (PAHs). These were compared to state guidelines for safe residential soil levels.

Despite the concerning findings, the report indicated a significant drop in health risks in areas where soil and debris were cleared by the U.S. Army Corps of Engineers. However, officials cautioned that some locations may still pose risks due to harmful materials.

As we look at similar situations historically, the concern over lead in soil isn’t new. In the past, many urban areas faced issues from outdated construction materials. Continual monitoring and updated building regulations have become essential in preventing such hazards.
