New UBC water treatment zaps ‘forever chemicals’ for good

New UBC water treatment zaps ‘forever chemicals’ for good

Engineers at the University of British Columbia have developed a new water treatment that removes “forever chemicals” from drinking water safely, efficiently – and for good. “Think Brita filter, but a thousand times better,” says UBC chemical and biological engineering professor Dr. Madjid Mohseni, who developed the technology. Forever chemicals, formally known as PFAS (per-and polyfluoroalkyl substances) are a large group of substances that make certain products non-stick or stain-resistant. There are more than 4,700 PFAS in use, mostly in raingear, non-stick cookware, stain repellents and firefighting foam. Research links these chemicals to a wide range of health problems including hormonal disruption, cardiovascular disease, developmental delays and cancer.

Clean water for Oneida still years away

Clean water for Oneida still years away

As a years-long boil water advisory continues to drag out, there’s cautious optimism that clean water will be flowing to residents of Oneida Nation of the Thames. But it won’t be any time soon. In fact it could be a number of years yet before the community can lift its boil water advisory. "Over the holidays I heard from a lot of community members feeling a sense of hopelessness, but also a sense of guilt," said Oneida Councillor Brandon Doxtator, who oversees environmental issues for the community." Just taking a five minute shower has caused community members to be worried about their part of exacerbating the problem," he said.

Rebecca Zagozewski, executive director of the Saskatchewan First Nations Water Association, said she has seen contractors save on costs when building water treatment plants on reserves by using obsolete parts and failing to include maintenance manuals, ventilation or chemical rooms, and bathrooms. “Engineering companies will put in their bids obviously as low as they can go,” said Zagozewski.

“They cut corners every day, every day,” said Justin Gee, vice-president of First Nations Engineering Services Ltd. Gee said he encountered these recurring problems while overseeing the work of a construction firm, Kingdom Construction Limited (KCL), building a water treatment plant 10 years ago in Wasauksing First Nation, along the eastern shore of Georgian Bay, about 250 kilometres north of Toronto. “You have to be on them every step of the way,” said Gee, who was the contract administrator on the project. “You can’t leave them on their own.”

Building trust in its tap water will be Neskantaga’s next big challenge

Building trust in its tap water will be Neskantaga’s next big challenge

The chief of the First Nation in Northern Ontario that has suffered through the country’s longest continuous boil water advisory is hopeful that water coming out of the taps in the homes of Neskantaga will be safe to drink sometime in early 2021. The question now is: Even if public health and First Nation officials pronounce the water safe to drink, will anyone trust in the purity of what comes out of their taps?

Ottawa to probe contractors hired to fix longest-standing boil water advisory

Ottawa to probe contractors hired to fix longest-standing boil water advisory

Indigenous Services Minister Marc Miller is preparing to launch a third-party investigation into the business practices of consultants and engineering companies hired to end Canada's longest-standing boil water advisory — a probe that could extend to other communities, CBC News has learned. "The problem is we have a system for delivering infrastructure that always goes with the lowest bidder," Angus said. "When you have a big-ticket item, like a water plant that's very expensive to build in a community, costs and corners get cut and that's the danger. Neskantaga has been a nightmare situation."
