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…on the heels of Health Canada’s new guideline for lead in drinking water, Canada’s National Collaborating Centre for Environmental Health has prepared an 8-page document entitled “Testing for Lead in School Drinking Water-A Summary of Sampling Protocols.” Table 1 is a “Summary of sampling protocols for testing lead in school drinking water developed in Canada [...]
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 [...]
I came across what could be a very important article today which may not attract the attention of drinking water professionals as it has just been published in the CDCs Emerging Infectious Diseases journal which isn’t widely read in our circles. It identifies a relationship between Mycobacterium avium complex in humans and premise plumbing.
Happy New Year all! There has been a lot of interest in microplastics in water recently and it looks like this will be one this year’s hot research areas. They have the potential to be impactful on human health but a lot of science remains to be done.
A study measuring urinary fluoride levels in pregnant women in Canada has just appeared in the journal Environmental Health Perspectives. The authors conclude that “community water fluoridation is a major source of fluoride exposure for pregnant women living in Canada.”
Following up from the just-published article “Community Water Fluoridation and Urinary Fluoride Concentrations in a National Sample of Pregnant Women in Canada,” I circulated earlier today; I have located the article that was referenced to support their conclusions pertaining to health risks.
A study looking at the extent of cyanobacterial cell accumulation and presence of five cyanotoxins across the treatment trains of four drinking water treatment plants in the Great Lakes region...
When discussing proposed lead in drinking water guidelines recently, the topic of lead in point-of use devices/plumbing materials and NSF 372 came up.
The deadlines for providing comments to Health Canada on their ‘Guidance document on the use of quantitative microbial risk assessment in drinking water’ and ‘Proposed guideline technical document on copper in drinking water’ documents have expired but a ‘Proposed guideline technical document on strontium in drinking water’ is now available for public comment ...
