Long Beach swimming areas were ordered closed after 15,870 gallons of sewage spilled Friday into the Los Angeles River, which dumps into the ocean in Long Beach.

The Long Beach Health Department is monitoring the water quality around the coast, but Long Beach City Health Officer Dr. Anissa Davis ordered all swimming areas west of Granada Beach to close "out of an abundance of caution," according to Long Beach officials.

The beaches will reopen once the water quality meets California requirements, officials said. The sewage spill, which happened in Los Angeles, was caused by a pump failure, according to officials.
