The Department of Health warned the public of high levels of enterococci at Laniakea on Oahu. 

During a routine inspection, enterococci levels were 2,005 per 100 milliliters.

Enterococci is fecal bacteria, which comes from human and animal waste and may threaten public health and coral reefs. In humans, enterococci has caused urinary tract infections, meningitis, gastrointestinal symptoms (nausea, vomiting, stomachache, diarrhea, headache or fever), rashes, ear, eye, nose and throat infections, and more. 

“Swimming at beaches with pollution in the water may make you ill,” the DOH’s notice said.

The advisory will remain in effect until water sample results no longer exceed the threshold level of 130 enterococci per 100 milliliters.

The DOH’s Clean Water Branch monitors water quality at beaches, alerting the public through a Brown Water Advisory website and notification system.
