Families left in the dark about when it’s safe to return home and who’s responsible for testing ashes for chemicals and toxins.
LOS ANGELES—Anita Ghazarian and Simon Penny live in a house on the westernmost edge of Altadena—missed by the flames from the catastrophic Eaton Fire, but still close enough to be blanketed in ash. Farther east, in the burn zone, they own a house they rent out, which was minimally damaged.
As soon as the electricity comes back on, Ghazarian’s insurance adjuster told her, the rental house is considered habitable.
“How can I tell my tenants to move back into a house where the entire backyard is filled with ash and broken stuff and the houses around it are all burn zones? Are the kids going to play in that backyard?” Ghazarian asked.
In a maze of online maps, residents can find themselves in an uncertain space: Their house might be in an EPA “normal” zone, meaning it has been repopulated after evacuations, and also marked green on a county map (showing no or minimal damage), and yet surrounded by obliterated structures and covered in ash.
Such intact structures risk being cross-contaminated by nearby burned structures, according to research from the University of Colorado at Boulder that looked at health impacts from smoke in homes after the Marshall Fire, which destroyed more than 1,000 buildings in 2021.
After Colorado’s Marshall Fire, more than half of the hundreds of people surveyed experienced symptoms from wildfire smoke six months after the fire, and continue to report symptoms even after extensive remediation.
Homes untouched by the fires had high levels of volatile organic compounds (VOCs), including benzene and toluene, carried in by ash and smoke from the homes that did burn.
In scope and scale, the Los Angeles disaster dwarfs the tragic Marshall Fire, and threatens a commensurate environmental crisis.
Los Angeles County’s two major fires, in the Pacific Palisades and Altadena, burned through 40,000 acres, about 60 square miles, and killed 25 people, destroying more than 16,000 structures and reducing whole neighborhoods to rubble.
