ONTARIO, N.Y. — Residents of the town of Ontario are under a boil water advisory for the next few days due to possible contaminants that may have seeped in early Sunday morning.
At approximately 3 a.m. a water main break caused a leak near the entrance of the Ginna Nuclear Power Plant along Lake Road.
The water main break has since been repaired.
“All the residents within the town are in a water boil advisory.
I do want to make sure that’s clear, it’s only the town of Ontario.
The disinfectant of the soaps will take care of it.
If you want to err to caution on the dishes, use bottled water or boiling water,” added Cummings.
Residents said they aren’t too concerned, but wanted to take the safe approach stocking up on water to make sure their family members and pets are safe.
“When an outside source lets it infiltrate into the system because it’s going through soil and sediment you could have bacteria from a whole slew of wastes that are in the ground, the coliforms, fecal, e-coli.
Cummings says something like this has never happened and it’s the first ever town-wide boil water advisory.
