Altadena Residents Face Toxic Challenges Post Fire

In Altadena, California, locals are going to great lengths to combat contamination following the Eaton Fire. This fire resulted in an unusual urban blaze, leading to the release of harmful substances like arsenic and asbestos. Thousands of homes and vehicles burned, releasing heavy metals into the environment.

Jennifer Rochlin, a ceramic artist, discovered lead throughout her home using an Amazon test kit. She faced challenges in getting her insurance company to cover lead testing until she detected the metal herself. Her situation, shared by many, highlights the ongoing struggle of Altadena’s residents.

Sixteen months post-fire, many people remain displaced. A report notes that nearly two-thirds of those whose homes burned or suffered smoke damage still live in temporary housing, often at personal expense. The uncertainty of when it will be safe to return or rebuild drives residents to seek outside help from scientists and advocacy groups.

Dawn Fanning leads the Eaton Fire Residents United group, helping those affected. She notes that the response systems are not equipped to handle this unique disaster. Insurance companies, local governments, and environmental agencies face challenges finding solutions in new circumstances.

California lacks specific safety standards for certain indoor contaminants found in Altadena. This lack of standards complicates decisions about when it might be safe to return home. Inconsistencies in testing methods add further challenges.

On properties where homes burned, agencies like FEMA and the U.S. Army Corps of Engineers did not include soil testing in their scope. This decision left many residents uncertain about lingering dangers, especially as two whistleblowers expressed concerns about rushed and inconsistent cleanup efforts.

The mission as assigned covered the removal of structural ash and debris, and the top six inches of soil in the ash footprint and structural foundations,” an Army Corps spokesperson said.

Altadena sits near the San Gabriel Mountains, offering a scenic yet hazardous setting due to recent fires. The Eaton Fire destroyed thousands of homes in 2025. Particles from materials like lithium batteries and old building materials became airborne, adding to the complexity of the disaster.

During the fire, Alireza Namayandeh, a postdoctoral fellow, collected smoke samples, learning about the particle size. His research indicates the presence of nanoparticles capable of entering the human body more easily.
