The state Department of Health is advising the public to stay out of the water at Keehi Lagoon Beach Park because of contamination from sewage. 

Warning signs are being posted Thursday by the City and County of Honolulu and water samples taken by DOH and CCH are being tested, according to a news release issued by the Department of Health Thursday afternoon.

On Wednesday, DOH officials responded to a report of an unknown discharge occurring within a drainage channel along Nimitz Highway. The source of the discharge was a damaged 10-inch gravity sewer main, which was spilling into a storm drain. The City and County of Honolulu patched the break. 

Officials reported the discharge of sewage stopped at about 7:30 p.m. Wednesday.
