Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
A new courthouse in Abbotsford has been found to have copper and lead in its water. In a statement to CBC News earlier this week, B.C.'s Ministry of Citizens' Services confirmed water testing completed in August 2022 at the Abbotsford Law Courts showed copper and lead levels "modestly in excess" of those permitted by regulatory standards.
Point-of-use (POU) dispensers, referring to those directly connected to the water supply lines, are widely used in public facilities such as schools and universities in Taiwan. These dispensers are equipped with filters that can remove contaminants, including heavy metals in drinking water. Assessment of water lead (Pb) levels rely heavily on sampling surveys that involve various sampling protocols. This study evaluated the effects of using first draw (FD), flush (FL) incorporating at least 20 s of flushing, and random daytime (RDT) sampling protocols on Pb level assessment in water samples collected from faucets and POU dispensers of a Pb pipe-free campus between March 2017 and July 2020. This was the first study to examine the influence of POU dispensers on different sampling protocols and their survey results. Pb levels in 19% of faucet and 11% of dispenser samples exceeded the Taiwan EPA standard of 10 μg/L. FL sampling produced the lowest Pb levels, followed by RDT and FD in the samples collected from faucets. Interestingly, all three sampling protocols exhibited similar Pb levels in samples collected from dispensers. Thus, any of the three sampling protocols can be employed to monitor Pb levels in water samples collected from dispensers.
Untreated wastewater and stormwater are no longer flowing untreated into Halifax harbour three days after a pump failed at Halifax Water's Duffus Street pump station. The pump began operating again at 4 p.m. Friday and was monitored overnight, Halifax Water said in a media release Saturday. Wastewater and stormwater are now being pumped from the station to the wastewater treatment facility on Upper Water Street.
Following public uproar of the Alberta government quietly pulling the 1976 coal policy, opening up more areas of the province for coal mining, a Calgary committee has started work to find out how those changes could affect the city on the Bow and Elbow Rivers. “The good news is, we found out today that although there’s different (land use) categories, the main category of the national parks and everything for our river system in the Bow is not affected with this policy,” Ward 1 Coun. Ward Sutherland said. “Obviously we’re very pleased with that.”
Like the rest of us, Canadian water and wastewater organizations are having to adjust to COVID-19 as the pandemic continues to impact the country. For example, the Regional District of Okanagan-Similkameen (RDOS) in southern British Columbia asked its residents recently to not flush sanitizing wipes down the toilet or pour fats, oil and grease (known as FOG) down the drain. “In this challenging time, when we are spending more time at home, as we do our part, we must be conscious that our homes have to function,” said Rina Seppen, RDOS wastewater utilities foreman in an announcement. “The last thing we need is to have the sewer lines clog and essential services stretched as we work to serve the public needs.”
One in five Winnipeg homeowners with lead pipes will get unacceptable levels of lead in their drinking water the moment they turn on the tap, according to the City of Winnipeg. Under the city's lead water quality testing program, samples were taken from 268 homes with lead pipes between Aug. 15 and Nov. 19. The testing was done to ensure water quality met new national guidelines for lead in drinking water, which cut the acceptable amount of contamination in half last March. "Overall, the results are as expected," Renee Grosselle, manager of environmental standards with the City of Winnipeg, told reporters Tuesday afternoon.
