Dockweiler State Beach in Los Angeles remained closed Thursday after waste including hypodermic needles, tampon applicators and condoms washed up on shore and excessive levels of bacteria were found in the water.
County health officials announced the closure Wednesday evening when the waste was spotted in the sand along the nearly 4-mile-long beach.
The environmentalist group Heal the Bay, which does regular water monitoring, said the waste may have been discharged from a pipeline belonging to the city-owned Hyperion Treatment Plant.
