Sediment contamination raises hidden health risks for beachgoers—what you need to know before visiting.
Recent tests reveal that toxic materials from the Palisades Fire, such as arsenic and debris from vehicles and electronics, have reached the sand on popular LA beaches through runoff. While the ocean water quality has returned to normal, hazardous substances have been found in coastal sediments.
Authorities, including LA County Public Health, currently state that beach recreation is safe. However, environmental groups like Heal the Bay warn that high arsenic levels, especially near Will Rogers State Beach, pose long-term health risks, particularly to children and pets.
There’s concern over the lack of clear safety standards for beach contamination after urban wildfires. Political tensions rose after FEMA refused funding for broader testing. Removing contaminated sediment is difficult due to the risk of releasing more toxins and worsening beach erosion.
Officials suggest that visitors use caution, especially avoiding areas north of Montana Avenue. Experts recommend families stay on dry sand farther south and remain vigilant about possible long-term health effects.
