Michigan Plans to Use New Method to Monitor Beaches for E. Coli

The Mitten State will become the first to monitor beaches for E. coli using a new, high-tech method.

It identifies the bacteria’s DNA and gives results the very same day.

That lets officials close beaches quickly when conditions are unsafe.

Using older methods required waiting to see if cultures grew in water samples, which usually meant not closing beaches until it was too late.

The DEQ plans to use both methods to compare results and see how the new one works.
