LOS ANGELES (CBSLA.com) —Los Angeles County health officials warned beachgoers Wednesday to be careful when they swim, surf or play in the ocean around discharging storm drains, creeks and rivers until Saturday.

Dr. Jonathan E. Fielding, the county’s public health officer, said hazardous materials from streets and mountain areas may enter ocean water because of the rainfall.

“There is the possibility that bacteria or chemicals from debris and trash may contaminate the water near and around these areas, and some individuals may become ill,” he said.

Fielding continued, “Fortunately, the discharging storm drains, creeks and rivers only comprise a small portion of the beach, and therefore, anybody who wants to go to the beach will be able to enjoy their outing.”

The beach warning could be extended past the weekend depending on more rainfall.
