A statewide brown water advisory is issued for the Hawaiian islands. Heavy rains have resulted in storm water runoff entering into coastal waters. The public is advised to stay out of flood waters and storm water runoff due to possible overflowing cesspools, sewer, manholes, pesticides, animal fecal matter, dead animals, pathogens, chemicals, and associated flood debris. Not all coastal areas may be impacted by runoff. However, if the water is brown stay out.
Warning signs were posted at Sandy Beach in East Oahu after a nearly 1-million gallon wastewater spill. Hawaii American Water issued a statement that on August 25, their plant across the street from the beach experienced a power disruption that affected their chlorine pumps.
The company says because the wastewater was partially treated and released about a quarter mile off-shore, it did not pose significant risk to beachgoers.
