There are dozens of municipalities across Canada that still use asbestos cement water pipes, servicing homes, businesses and schools. Regina, Saskatchewan has 600 kilometres of asbestos cement water pipes. “These pipes are experiencing more and more failures in recent years and account for almost all of the water main breaks in the city,” reads an NRC report on the matter. The report goes on to refer to asbestos fibres in water as a “health concern.”
Pesticides and Water Pollution
Source Water Protection
Drinking water is best protected by taking an approach that uses multiple barriers to prevent contamination from affecting our drinking water. Known as the 'multibarrier approach', it includes taking actions to prevent contamination of sources of our water, using adequate water treatment and distribution systems, water testing and training of water managers.
Detailed Escherichia Coli
Escherichia coli, also referred to as E. coli, is a type of fecal coliform bacteria that is found in the intestines of healthy warm-blooded animals and humans. Most E. coli strains are harmless and serve a useful function in the body by stopping the growth of harmful bacteria species and by making necessary vitamins. However, some strains can be opportunistic pathogens, while others can cause gastrointestinal illness in healthy humans when ingested.
