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

Because of debris runoff from fire zones, public health officials issued an advisory and closed several miles of coastline from Malibu to Playa del Rey.
