Wildfires tore through Los Angeles in January 2025, burning more than 16,000 structures, uprooting neighborhoods and displacing entire communities. As the infernos raged, DRI scientists with a wide range of expertise in soil science, air quality, and post-wildfire impacts put together a plan for collecting ash, dust, soil, and building material samples from the burn zones. To them, these urban fires presented a unique opportunity to understand how materials like plastics, metals, and even lithium batteries from electric cars can transform into environmental contaminants when they burn.
