San Diego

About 3,000 gallons of raw sewage spilled from Point Loma into San Diego Bay Monday, public health authorities reported.

The spill occurred near Kellogg and San Gorgonio streets when a sewer pipe became clogged with tree roots, according to county health educator Cheri Eir.

Pressure forced sewage from one ruptured pipe to the street surface through a crack in the pavement. The sewage then flowed into a storm drain that empties into the bay at the foot of Kellogg, Eir said.

A distance of 100 yards along the bayfront was posted with contamination warning signs, Eir said. County health workers will test samples of the contaminated water daily until its quality reaches a safe level for swimming, Eir said.
