LA County testing finds elevated lead in Altadena soils after Eaton Fire, complicating rebuilding

An After-Action Report found systemic failures in L.A. County’s response to the January 2025 Eaton and Palisades fires—which killed more than 30 people and destroyed thousands of homes—citing staffing and resource shortages. County soil testing in Altadena found many properties with lead above California’s 80 mg/kg screening level, and independent USC testing shows contamination persisted after the Army Corps scraped six inches of soil; with over a third of homeowners lacking desired tests, some will need hazardous soil removal before rebuilding, complicating recovery.

🔍 Key Facts

  • An After-Action Report by the McChrystal Group (released the week of Sept. 26, 2025) found systemic failures in LA County's emergency response to the fires, citing staffing shortages (including sheriff deputy vacancies), an under-resourced Office of Emergency Management, only four staff trained on Genasys alert software after a November contract expansion, and unreliable cellular/connectivity and field reporting platforms.
  • The Eaton and Palisades fires in January 2025 killed more than 30 people and destroyed thousands of homes in Altadena and Pacific Palisades.
  • L.A. County Department of Public Health's final soil testing found a sizeable number of Altadena properties with lead concentrations above California's safe level of 80 mg/kg, raising health and rebuilding concerns.
  • Caltech data show more than 90% of homes in Altadena were built before 1975, increasing the likelihood of legacy lead paint contributing to soil contamination.
  • USC's CLEAN testing program reported that contamination persisted at some sites even after the Army Corps scraped six inches of soil, suggesting scraping alone may not remove all hazardous lead contamination.
  • More than one in three Altadena homeowners say they have not obtained the soil testing they want; some homeowners will need to remove hazardous soil before rebuilding, complicating recovery and reconstruction efforts.
