Some community members in Fort Resolution, N.W.T. are worried the water supply might be contaminated, and want to know who's responsibility it is to make sure it's safe to drink.

Tom Unka says the community's lagoon is 40 years old and some people are worried contaminants are seeping into Great Slave Lake.

"Why am I concerned? Because I drink the water here and everybody here is always very concerned, especially the elders during the summer months where they're a lot of illness related to the stomach," he says. "We kind of always suspected that it could be our water. The elders are telling us 'check the water, it's probably the water'," he says.

Duane Flemming, the chief environmental health officer for the territorial government, says the water is perfectly safe.

"They test the water at least three times a day for turbidity and free chlorine risidual, that's the most important test," he said. "On a weekly basis they take samples of the water for total choliform and e coli and there's never been a positive sample for e coli. As well, on an annual basis, there's chemical analysis done of the drinking water," Flemming says.

Unka says the community has requested the lagoon be moved further inland — away from the lake — but were told it would be too costly.
