Long Beach health officials closed coastal beaches Monday after 11,000 gallons of sewage was discharged into the San Gabriel River on Sunday.

Los Angeles County reported to the city on Monday that the spill came from the city of Hawaiian Gardens and was caused by a grease blockage.

City health officials are monitoring the situation, and will continue to do so until test results show the water quality complies with state standards, officials said in a statement today. The closure does not affect Alamitos Bay.

State law requires closure of beaches and that notices be posted until tests are clear.

Long Beach has roughly seven miles of public beach.
