A City of Port Angeles sewer treatment plant released about one million gallons of sewage — “insufficiently disinfected effluent,” according to Clallam County officials — into the Strait of Juan de Fuca Sept. 2 and Sept. 3.

Beginning at about 1 p.m. on Sept. 2, the sewage was released from an effluent discharge pipe in the Strait at a depth of about 60 feet, according to county officials.

Those officials say the risk of water contamination at Port Angeles beach and water recreation areas is low; however, the county Health and Human Services’ Environmental Health Department is advising the public to avoid contact with Port Angeles Harbor water for the next seven days.

Contact with fecal contaminated waters can result in gastroenteritis, skin rashes, upper respiratory infections and other illnesses, county officials said, and that children and the elderly may be more vulnerable to waterborne illnesses.
