Microbial contamination of groundwater from private wells can pose a significant health risk to rural Canadians. To mitigate risk, Health Canada currently recommends shock chlorination along with microbial well testing, voluntary measures most often performed by the homeowner. However, infrequent testing and paucity of research assessing the effectiveness of shock chlorination guidance as...

Boil water advisories are issued when water testing detects higher than accepted amounts of microbial indicators or when there are deficiencies with water treatment. The fear of not issuing a boil water advisory when there is truly a health risk associated with water consumption can lead water operators to call for boil water advisories as a precautionary measure. Yet, issuance of boil water...

Can irrigation of food crops using surface water affected by cyanobacteria blooms result in bioaccumulation of cyanotoxins in these crops?
Can cyanotoxins bioaccumulate to a concentration that might cause a public health...

Fluoride has been added to public drinking water in Canadian communities since the 1940s as a means of preventing tooth decay. Dental fluorosis is a known adverse effect of excessive fluoride exposure during tooth formation. Fluorosis ranges from barely noticeable whitish striations in the enamel to severe pitting and brownish staining. In general, the prevalence of dental fluorosis in...

Information about Canadian drinking water systems and past water-borne disease outbreaks is incomplete and non-standardized. Standard definitions and coordinated surveillance systems for water-borne disease outbreaks would help inform policy and practice. A relatively high proportion of past water-borne disease outbreaks in Canada are estimated to have occurred in small drinking water systems...

American Public Health Association (APHA) - Drinking Water and Lead Service Lines: Partnering to Protect Public Health
Lead exposure contributes to cognitive impairments, behavioral problems and lowered IQ. While there is no safe level of lead exposure, lead can be found in dust in our homes, air, soil, and drinking water. Lead service lines are the largest source of lead in drinking water - with an estimated 6-10 million lead service lines bringing water to taps across the U.S. Following the tragedy in Flint,...
