Beaches in Port Huron, Marysville under swim advisory

Holland Beach in Port Huron and Chrysler Beach in Marysville were placed under a swim advisory on Thursday due to elevated presence of E. coli.

The St. Clair County Health Department issued the advisory and the beaches have been closed for now. Water samples will be collected at these beaches until E. coli test results are within acceptable water quality range as advised by the state of Michigan.

E. coli bacteria are a common microbe found in the digestive systems of warm-blooded animals, including humans, and can indicate the presence of fecal contamination.

Beach goers should be aware that elevated E. coli levels are possible after a storm or strong winds because bacteria are carried in storm water runoff and stirred up by waves.

Advisories for St. Clair County public beaches are shared on the health department's "St. Clair County Beaches" Facebook page and Michigan BeachGuard website at www.egle.state.mi.us/beach/.
