WAIANAE, OAHU (HawaiiNewsNow) - The Hawaii Department of Health is urging the public to stay away from a sewage-contaminated drainage ditch in a residential area near Waianae Mall.
The pollution hasn't gone into near-shore waters, according to the Hawaii Department of Health.
The DOH Clean Water Branch began its investigation after a sewage spill from a private commercial property near Farrington Highway on Tuesday.
More than 10,000 gallons of raw sewage is estimated to have seeped from a damaged sewer pipe on the property. The leak resulted in a spill that flowed from the sewer line onto the highway and into the drainage ditch near Lualualei Beach Park.
The owners of the broken sewer pipe were notified by the Clean Water Branch, and are required to remove the contaminated water to prevent further risk to the environment and human health.
Warning signs are posted on Farrington Highway and the west side of the ditch near Lualualei Beach Park.
The cause of the sewage spill is still being investigated.
