Cyanobacteria, commonly known as blue-green algae, are naturally occurring microscopic organisms found in fresh, brackish, or marine water that can release cyanotoxins into freshwater systems. These toxins can pose a serious public health risk as exposure through skin contact, or ingestion of contaminated drinking water or food can cause symptoms ranging from minor irritation to more serious...

Lead is a potent neurotoxin that is commonly present in our environment and can have serious, irreversible cognitive and behavioral impacts, particularly in children. Historically, most lead exposure has occurred through inhaling leaded-gasoline combustion products in the atmosphere; this contribution has drastically declined due to the global phase-out of leaded gasoline. Other sources of...

Floatation or float tanks have resurged in popularity since their initial commercialization in the 1970s. These tanks, pods, or chambers are intended to help users achieve certain physical and mental benefits through the elimination (or minimization) of sensory inputs. Briefly, the user floats on his or her back in a warm, near-saturated solution of magnesium sulphate (MgSO4), which buoys the...

In Canada, most people have access to safe and secure drinking water. Nevertheless, lapses in management of drinking water safety may lead to waterborne illness outbreaks, which can lead to high personal and economic tolls as a large number of people may be exposed to disease agents simultaneously. Investigation of waterborne illness outbreaks is challenging due to rarity of occurrence,...

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...

Low level lead exposure has been linked to neurobehavioral and cognitive effects in children.1 No “safe” level of lead exposure exists and efforts should be made to reduce exposures to as low as possible. The phasing out of lead in gasoline, residential paints, and solder in food cans has substantially decreased blood lead levels among the general population, but residual sources still exist....

Topics: Cyanobacteria, Drinking Water, Recreational Water, Water General, Canada
With warming temperatures due to climate change and increased nutrient loads to freshwater systems, the occurrence of harmful algal blooms, largely associated with toxin-producing cyanobacteria, is expected to increase across Canada. While cyanoblooms have affected Canadian waterbodies for many years, the potential to negatively impact drinking water supplies is considered an emerging area of...

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...

Health officials often lack information about characteristics that predict which water systems are most likely to be placed on and to persist on drinking water advisories (e.g. health warnings offering advice or information). This study uses data collected by the Interior Health Authority in British Columbia to characterize water systems on advisory for microbiological threats and to identify...

While boiling water is an effective way to kill most microbial pathogens, research performed in the United Kingdom has shown that people do not necessarily comply with boil water advisories. Similarly, in Walkerton, Ontario in 2000, only 44% of respondents reported that they were aware of the order to boil water when it was first issued on the local radio at the start of the outbreak and in...

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,...
