Guidelines for Canadian Drinking Water Quality – Guideline Technical Document: Cyanobacterial Toxins
The ‘Guideline Technical Document: Cyanobacterial Toxins’ is now available on Health Canada's web site.
Low risk posed by engineered and incidental nanoparticles in drinking water
A just published review article on the risk of engineered and incidental nanoparticles in drinking water concludes risks to human health are low.
Poikilothermic Animals as a Previously Unrecognized Source of Fecal Indicator Bacteria-important new research finding
I learned today what ‘poikilothermic animals’ are (those with body temperatures that vary with the ambient environmental temperature, such as fish, frogs, and snails) and why, as drinking water professionals, we should care.
Potential impacts of changing supply-water quality on drinking water distribution: A review
Not too long ago the Flint water crisis drew our attention to the observation that changing the raw water source to a drinking water treatment plant needs to be done with due care and diligence.
Persistence of Viruses by qPCR Downstream of Three Effluent-Dominated Rivers in the Western United States
If you are like me you probably wonder why pepper mild mottle virus (PMMoV) is being suggested by authors of this just published paper as a viral indicator (surrogate) for fecal contamination in water (instead of enteric viruses, adenoviruses or noroviruses).
Public Consultation Guidelines for Canadian Drinking Water Quality – Guideline Technical Document on Strontium
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 at...
Identification, toxicity and control of iodinated disinfection byproducts in cooking with simulated chlor(am)inated tap water and iodized table salt
In an effort to avoid chlorinated disinfection byproduct (DBP) formation in distribution systems many drinking water utilities switched from free chlorine to chloramination.
Review of Epidemiological Studies of Drinking-Water Turbidity in Relation to Acute Gastrointestinal Illness
A review of “Epidemiological Studies of Drinking-Water Turbidity in Relation to Acute Gastrointestinal Illness” has been published in the journal Environmental Health Perspectives.
Growth and Extended Survival of Escherichia coli O157:H7 in Soil Organic Matter
It is widely assumed that an important waterborne pathogen, Escherichia coli (E. coli) O157:H7, is shed from warm blooded animals and in some instances is transported to a drinking water treatment plant intake/source.
Microbial Diversity and Putative Opportunistic Pathogens in Dishwasher Biofilm Communities
In my quest to find new and interesting topics in drinking water research this is the first study I’ve come across on dishwashers. No municipality that I’m aware of is responsible for appliances connected to distributed networks.
