High levels of arsenic detected in 112 wells across N.L. — and hundreds more could be at risk

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.

Of just over 1,000 test results, the department reported 112 wells with arsenic levels above 10 parts per billion, the limit imposed by Health Canada.

Anything over that amount places the drinker at risk of myriad diseases, including skin lesions, neurological problems and several cancers.

Minister Bernard Davis told CBC News his department still has a few hundred tests left to give out. The samples are sent to a provincially owned lab, and cost only a few dollars each to process.

"We've seen some pretty good uptake," Davis said.

"It's providing pretty much real-time information to the people that submit the samples, so they know exactly what the quality of their water is."

Those over the safe limit can install a special filtration system, or import their drinking water from elsewhere.

But with around 40,000 private wells dotting outports across Newfoundland and Labrador, one Memorial University researcher says the program should expand.

At a presumed 10 per cent risk rate, Sarkar points out some 4,000 households could be drinking arsenic without any clue the odourless, colourless toxin has infiltrated their water supply.

"These free test kits are actually an investment in health, public health," he said.

"By that logic you are actually saving a good number of [the population] from future illnesses, which might be very expensive in terms of health-care costs."

The provincial government has known about arsenic deposits for decades, but for well owners like Moreton's Harbour resident Debbie Rideout, the message that her family could be at risk simply never reached her.

Rideout was informed her water contained 80 times the safe limit after a local doctor pushed for testing in the community. Her husband and children had been drinking the water for years at that point, she said.
