The state Department of Health issued a brown water advisory for the islands of Oahu, Maui  and Kauai, warning people to stay out of flood waters, storm water runoff and coastal waters that have turned turbid and brown.

The waters may be contaminated with sewage, pesticides, animal fecal mater, dead animals, chemicals, pathogens and debris, the Health Department said.

The Health Department says 27,700 gallons of wastewater overflowed on Lihue Street in Waianae into Kaupuni Stream and Pokai Bay. Another 3,975 gallons went into Halawa Stream and Pearl Harbor from a sewer manhole overflow at Piikea Street in Foster Village and 3,000 gallons overflowed at the Kaneohe Pre-Treatment Facility in to Kawa Stream and Kaneohe Bay.

Another overflow from a sewer manhole at 87-154 Maipalaoa Road is entering Maili Stream, the Health Department reported. Other sewer manholes in Waianae and other areas of Oahu may also be overflowing but difficult to see because of the heavy rain and flooding, the Health Department said.
