The waters off Los Angeles County may be contaminated by toxic or carcinogenic chemicals following the Palisades Fire, according to health officials, who indefinitely closed a portion of Santa Monica State Beach this week.

The ocean water remained off-limits Thursday at beaches stretching from Malibu to Santa Monica due to the recent rains and fire debris carried to the coast, while a water quality advisory was in effect for all beaches as far south as Playa del Rey.

The ocean water along roughly eight miles of prime Los Angeles coastline remained off-limits indefinitely due to the recent rains and fire debris.
