The Canadian Council of Ministers of the Environment (CCME) is looking for input into the draft Canadian Groundwater Quality Guidelines for the Protection of Environmental and Human Health for 101 contaminants of concern. It is available for public review and comment until January 10, 2020.
I’ve seen some news reports that prosecutors have dismissed all charges in the Flint water crisis investigation (recall that there were two issues, lead which was the focus, but also Legionnaires disease which was not considered in the original investigation)...
Health Canada is hosting a 1.5 hour webinar entitled ‘Guidelines for Cyanotoxins in Drinking and Recreational Water’ on Wednesday, May 29, at 1:30 pm EDT. There is no cost for this webinar, but the number of participants is limited.
Guidelines for Canadian Drinking Water Quality – Guideline Technical Documents: Enteric Protozoa and Enteric Viruses formalized
Two new guideline technical documents for Canadian Drinking Water Quality are now available on Health Canada's website.
Analysis of cyanobacterial metabolites in surface and raw drinking waters reveals more than microcystin
As drinking water professionals we have turned our attention to the latest potential threats including for example microplastics, perfluorinated compounds, and cyanobacterial toxins.
Hi all…with spring just around the corner, for some of us anyway, an interesting paper entitled “Persistence of fecal contamination and pathogenic Escherichia coli O157:H7 in snow and snowmelt” has recently been published. There has been a substantial amount of research conducted in the area of watershed protection as a key element in the production of safe drinking [...]
National Trends of Bladder Cancer and Trihalomethanes in Drinking Water: A Review and Multicountry Ecological Study
There have been a number of studies which have been unable to link the risk of certain cancers with trihalomethanes (THMs) in drinking water over the past couple of decades. In a just published review, the authors examined trends in the incidence of bladder cancer in 8 countries in the 45 years since THMs were detected in chlorinated drinking water...

It identifies a relationship between Mycobacterium avium complex in humans and premise plumbing.
Poikilothermic Animals as a Previously Unrecognized Source of Fecal Indicator Bacteria-important new research finding
