The Los Angeles County Public Health Department is cautioning beachgoers to avoid all contact with the water at local beaches due to the potential presence of harmful bacteria, chemicals, and trash washed in from recent heavy rains and street runoff.

Heavy rainfall can flush a variety of pollutants and contaminants from urban areas into coastal waters, posing a serious public health risk to swimmers, surfers, and other beachgoers. This is an ongoing issue in Southern California, where storm drains and sewers often overflow during intense storms.

The details

According to the public health advisory, the combination of bacteria, chemicals, and debris in the water can cause skin rashes, stomach illness, and other health problems for those who come into contact with the contaminated ocean. The warning applies to all beaches in Los Angeles County until further notice.
