The Department of Health has posted advisory signs to notify the public of high levels of enterococci at a section of Waikiki Beach.
Water samples collected Monday morning in waters fronting the Moana Surfrider indicate elevated levels of enterococci at 150 colony forming units per 100 milliliters, exceeding the recreational water quality standard of 130 cfu per 100 milliliters.
Runoff from Saturday’s thunderstorm is believed to be the cause of the high count, said Stuart Yamada, chief of the Environmental Management Division.
Officials warn the public that contact with the water may cause nausea, stomach pains, diarrhea or fever. It also may cause infection to the eyes, ears, nose and throat.
Yamada said advisory signs will remain posted until water samples no longer exceed the water quality standard.
The Clean Water Branch is expected to return to the beach today to collect water samples. “It takes at least 24 hours to get a sample result,” he said.
