Why are beaches monitored?
Part 125 of Act 368, Public Acts of 1978, provides for testing and evaluation of public bathing beaches by local health departments. The St. Clair County Health Department monitors 8 beaches in St. Clair County weekly from Memorial Day to Labor Day. Samples are generally taken one foot below the surface in water that is approximately three feet deep.

Why do beaches sometimes close?
The Michigan Public Health Code sets standards that limit the levels of E. coli at beaches called Total Body Contact Standards. A beach is closed whenever these standards are exceeded. Generally, following a heavy rainfall, the beaches may be closed due to polluted storm water run-off.

What is Escherichia coli (E. coli)?
E. coli bacteria are common microbes found in the digestive tracts of warm blooded animals, including humans. The presence of E. coli in water can indicate the presence of viruses and pathogens that can make us sick.

The Health Department monitors 8 public bathing beaches in St. Clair County from Memorial Day to Labor Day.

Keep our beaches healthy!
Common sources of E. coli come from animal waste, malfunctioning septic systems, and storm drains. When it rains, storm water becomes infected with pollutants and bacteria which contaminate our beaches. Here are easy ways you can help keep our water clean and beaches healthy!

WATERFOWL - Don’t feed the geese, ducks or gulls. If you feed them on the beach, they go on the beach. Their waste contains E. coli bacteria.
PETS - Clean up after your pet and immediately dispose of the waste in the trash. Pet waste contains E. coli bacteria too.
LITTER - Place litter, including cigarette butts and grill ashes, in trash cans.
STORM DRAIN - Never place anything down a storm drain, including litter, leaves, fertilizer, oil, or chemicals. Remember, only rain in the drain!
