The mayor of Nain says a dead dog found in the community's water supply was never a health risk for people consuming the water, even with a boil-water advisory issued.

On Friday, the community issued the advisory after two teenagers found a dead dog floating in the water supply.

However, AngajukKak Tony Andersen said the advisory was a precautionary measure to deal with concerns among the community, and there was never a health risk to anyone who drank the water.

"We issued the boil water order until we got word from the provincial water regulators on what we should do. Now, as soon as they got back to us they told us that we didn't need to issue a boil-water order because our chlorination levels were fine and there was no reason to issue it," he said.

Andersen said the order has since been lifted, and the water is safe for people to drink.

He added there is no way to prevent things like this from happening in an open water supply, and while he hasn't heard of it happening in his community before, it isn't generally uncommon.

"We have no control, whether it's bumblebees or birds, moose or dogs that get into that water supply, but before it's pumped to the community it is made healthy," Andersen said.

"The chlorination levels are checked each and every day, seven days a week, and as well once a month we send water samples off to the province for testing, and I must say that Nain's water supply is as good as it gets in this province."

Andersen said most communities in Newfoundland and Labrador get their water from an open source, as well.

He said the town is still trying to figure out where the dog came from, and how it came to be in the water supply.
