Based on daily water sample collection, E. coli bacteria test results show Lighthouse Beach and Holland Road Beach in Port Huron and Keewadhin Road Beach in Fort Gratiotare within the acceptable range and are now open. As of Thursday, August 20, all public beaches are open. In order to remain open, public beaches must meet the State of Michigan’s full body contact standards of 300 E. coli bacteria per 100 ml of water.
Yesterday’s advisories follow several days of rain. Elevated E.coli levels are possible after a rain storm or strong winds because bacteria are carried in storm water runoff into waterways or stirred up from waves. Residents should avoid swimming in surface water within three days of rain or if the water is stirred up and turbid.
The St. Clair County Health Department’s Environmental Health Division monitors public beaches in St. Clair County for the presence of E. coli from Memorial Day to Labor Day. Current advisories for St. Clair County’s beaches are shared on the SCCHD’s 24-hour Water Quality Hotline at 877-504-SWIM, “St. Clair County Beaches” Facebook page, the “MyBeachCast” app, and Michigan BeachGuard website at www.egle.state.mi.us/beach/.
