Manitoba wants to back out of $34M sewage-treatment promise, city says

February 1, 2019 – CBC News

Manitoba’s Progressive Conservative government wants to back out of a $34-million commitment to help Winnipeg pay for billions worth of sewage-treatment upgrades, and instead spend the money on other infrastructure projects, the city’s chief financial officer says.

The province denies Mike Ruta’s report and claims the city is attempting to move around money intended for upgrades at the North End Water Pollution Control Centre.

A report to city council’s finance committee, published Friday, says the province wants Winnipeg to redeploy $34.4 million it already gave to the city and use that cash to help pay for other projects it’s agreed to fund, including the Waverley underpass and transit projects.

Council finance chair Scott Gillingham (St. James) said he’s very concerned about the request considering Winnipeg is facing billions of dollars worth of sewage-treatment upgrades.

“To move any money off of wastewater treatment when we have these significant projects in the queue is very problematic,” Gillingham said Friday at city hall.

The potential redeployment of wastewater-treatment cash could further delay plans to conduct $1.4-billion worth of upgrades to the North End Water Pollution Control Centre, the largest of Winnipeg’s three wastewater treatment plants.

This is the largest component of a multibillion-dollar sewage-treatment upgrade ordered by the province in 2003 to reduce the quantity of nutrients that flow into the Red River and into Lake Winnipeg, where they help spawn algae blooms. READ MORE.

Canadian cities rethink removal of fluoride from tap water

Jan. 24, 2019 – CBC News

It shouldn’t be up to cities to decide to add fluoride to drinking water, but provincial officials, a Canadian mayor says.

Windsor, Ont., is bucking a national trend and looking at lifting its ban on adding fluoride to drinking water after seeing an increase in cavities among children.

Community water fluoridation is recommended by public health, medical and dental groups, including the Canadian and American Dental Associations, Canada’s Chief Dental Officer and the World Health Organization. The U.S. Centers for Disease Control and Prevention called its contribution to the decline in cavities one of the 10 great public health achievements of the 20th century.  

Fluoride is a mineral that binds to the enamel of teeth, strengthening them to prevent bacterial decay.

But ever since Canadian communities first introduced fluoridation in 1945, some cities have gritted their teeth at the contentious addition, and the debate continues. Some Windsor city council members initially argued that fluoride could be obtained cheaply from toothpaste and other critics have presented general fears over adding chemicals to water supplies. 

A 2018 review by the Canadian Agency for Drugs and Technologies in Health evaluated dozens of studies on the health effects associated with fluoridation. “The evidence in this review supports the protective role of community water fluoridation in reducing dental caries [cavities] in children and adults,” the authors concluded.

Lake Winnipeg fish species in ‘grave peril’ due to mismanagement, wildlife group says

Oct. 22, CBC News:

Some Lake Winnipeg fish species are on the brink of extinction due to “decades of mismanagement” of the commercial fishing industry, says the Manitoba Wildlife Federation.

“The issue of declining fish stocks in Lake Winnipeg is a direct result of commercial fishing policies that are not based on science,” said Brian Kotak, managing director of the wildlife federation.

“The harvest levels are unsustainable.”

Commercial fishers are allowed to catch a quota of any of the three main species — walleye, sauger and lake whitefish.

That system encourages intense fishing pressure on whichever species is most in demand, which has meant a heavier focus on walleye for many decades due to market prices, said the federation. Read more.

Event: Disentangling the Impacts of Climate Change and Human Interventions on the Hydrology of Key Canadian Watersheds

This presentation will explore climate change and flow regulation impacts on daily and annual river discharge variations and trends into Hudson Bay, the Nechako and Fraser River Basins over the past half-century or so. The first part of the presentation will focus on the 3.7 million km2 Hudson Bay drainage basin for which daily observed streamflow data from the Water Survey of Canada, Manitoba Hydro, Ontario Power Generation and Hydro-Québec for 21 rivers were used to analyze the basin from 1960 to 2016. Decadal hydrographs were developed to assess the changing hydrological regimes in both regulated and unregulated sub-basins and spectral analyses are used to infer the dominant modes of temporal variability on the river discharge input to Hudson Bay. While the unregulated systems exhibit signals of climate change, these remain secondary relative to flow regulation even at the larger Hudson Bay drainage basin scale.
