The Department of Health has removed warning signs from all beach areas affected by the Aug. 24 wastewater spill.

The signs were taken down on Saturday after recent testing indicated that the affected waters no longer posed a health threat. No further testing will be conducted, the department said.

An estimated 500,000 gallons of sewage emptied into the ocean at Ala Moana Beach Park, affecting the Ala Wai Small Boat Harbor, Kewalo Basin Small Boat Harbor, the canoe launch area adjacent to Ala Wai Small Boat Harbor, the pond and canal along Ala Moana Boulevard, and the western end of Kakaako Park.

A brown water advisory remains in effect for all islands as coastal areas continue to be vulnerable to contaminated runoff from recent heavy rains.

The public is advised to stay out of flood waters and storm water due to possible contamination from pesticides, animal fecal matter, dead animals, pathogens, chemicals and associated flood debris and from overflowing cesspools, sewers and manholes.
