The chief building official with the town of Fort Frances is opposing a change to the provincial building code.
The change will allow builders to connect non-potable water services to an existing municipal line.
Rick Hallam says it opens the door for toxins getting into the local water system.
"It could have anything in it," says Hallam, "from chemicals that are spilled, noxious or toxic, even to excrement from animals to human. We don't know. You have no control over what goes into that non-potable water supply."
Hallam is making his opposition known in a submission to the Ministry of Municipal Affairs and Housing.
