More than 100 households in Newfoundland and Labrador have learned their well water contains dangerous levels of arsenic — and hundreds more across the province may be drinking the toxin without knowing it. The Department of Environment recently released the first batch of results from its free testing program for private wells it announced last year.

U.S. issues new warnings on 'forever chemicals' in drinking water

U.S. issues new warnings on 'forever chemicals' in drinking water

The U.S. Environmental Protection Agency on Wednesday released new warnings for synthetic pollutants in drinking water known as "forever chemicals" saying the toxins can still be harmful even at levels so low they are not detectable.

That's about 60 per cent of some 1,000 kilometres of the mains that deliver water to homes around the city. Increasingly, some scientists and communities are questioning the wisdom in having drinking water flowing through pipes constructed from asbestos fibres.
