A portion of Newport Harbor is closed to swimming and diving after 750 gallons of raw sewage spilled into the water Saturday afternoon.
Sewage flowed from a storm drain into the water at Newport Marina at West Coast Highway and Newport Boulevard around 1 p.m., said Anthony Martinez, water quality program manager for the Orange County Health Care Agency.
The spill originated in a parking lot at 620 W. 17th St. in Costa Mesa after a pump station failed to move the sewage into the main line. Instead, it flowed into a storm drain and into the harbor, Martinez said.
Water quality tests are being conducted, and the earliest the closure could be lifted is Tuesday, Martinez said.
