Water Quality: Swimming Area

A volunteer in our community collects water samples periodically and has them tested for E. coli by Oakland County Health Division. He tests 3 areas within the roped swimming area, between the docks & middle rope.

The average reading level of E. coli should be below 300 CFU/100mL for safe swimming.
