The Environmental Health Division is responsible for monitoring public recreational waters in Washtenaw County. Staff inspect public swimming pools, and collect water samples from pools and beaches for bacterial testing. If the bacteria levels are unsafe, we will notify the pool or beach operators to take corrective action. The Environmental Health Division will close public beaches and swimming pools if unsafe conditions cannot be corrected immediately.
Washtenaw County Environmental Health does not routinely sample water bodies located on private property. If you are wondering if the pond or lake on your private property or in your subdivison is safe for swimming, or if you want to know how best to sample the water, please see our fact sheet: Is my pond or lake safe for swimming?
