Beaches west of Belmont Veterans Memorial Pier remain closed after a sewage spill contaminated local waters Thursday.

The city’s Health & Human Services Department announced the closure Thursday evening.

The spill originated some 25 miles north of Long Beach, according to the city announcement. An estimated 11,200 gallons of sewage escaped a Los Angeles County Public Works sewage line about 9 a.m. Thursday near LAC+USC Medical Center.

That resulted in some 8,300 gallons of sewage flowing into a storm drain before reaching the Los Angeles River. The river’s mouth is near downtown Long Beach.

Long Beach officials reported learning of the spill late Thursday afternoon from the Los Angeles County Public Health Department.

Members of the public can call 562-570-4199 to obtain updated information on beach closures from city government.
