Advisories on high bacteria levels at two beaches near Queen’s Surf in Waikiki remained in effect Thursday, a day after being posted by the state Health Department.

The levels of enterococci detected were about 10 times the threshold of 130 per 100 milliliters — 1,296 per 100 milliliters at Public Bath Beach and 1,445 per 100 milliliters at Kapiolani Beach.

Enterococci bacteria indicates possible contamination by fecal waste that could originate from wastewater treatment plants, septic systems, stormwater runoff, sewage discharge or even animal waste.

The beach at Hanauma Bay will be closed again today after an advisory for high bacteria levels was also posted Wednesday at the snorkling attraction. City officials said while the beach will remain closed, access to the upper park and visitor center will be open.

During routine beach monitoring, the state found levels of enterococci at Hanauma Bay had reached 137 per 100 milliliters. A high-bacteria advisory also was issued Wednesday for the Ewa side of Ala Moana Beach Park.

On Thursday afternoon state health officials canceled high bacteria advisories for Pokai Bay and the Kohola Lagoon at Ko Olina in Leeward Oahu but issued a new one for Kahaluu Beach park. Levels of 324 per 100 milliliters of enterococci were detected there.

Signs are posted at the affected beaches. Results from routine beach monitoring take at least 24 hours to process. A full list, maps and updates are available at the state’s Clean Water Branch web portal at eha-cloud.doh.hawaii.gov/cwb/#!/viewer.
