Public Beaches

Environmental Health Division staff collect water samples from the five public beaches throughout Washtenaw County from Memorial Day through Labor Day. To protect public health and to prevent the spread of disease, the samples are analyzed for E Coli bacteria levels.

The Michigan Public Health Code sets limits for levels of bacteria at bathing beaches open to the public. If the levels detected during monitoring exceed these limits, the risk of illness increases. Beaches are closed if deemed unsafe to public health.
