There is a boil water advisory for Greece Town Hall and nearly a dozen houses across the street.
It's because a contractor who was putting in water mains nearby injected some dye in the pipes to check for cracks, and some of that dye got into an active water main.
The dye is considered safe, but an official with the Monroe County Water Authority says they implemented the boil water advisory out of an abundance of caution until they get test results back.
That should happen late Thursday or early Friday.
