NSF/ANSI 60 and NSF/ANSI 61 updated for Canada and published as National Standards of Canada. ANN ARBOR, Mich. – The American National Standards for health effects of drinking water treatment chemicals (NSF/ANSI 60) and plumbing system components (NSF/ANSI 61) have been updated for the Canadian market and published as National Standards of Canada.
Drinking Water Chlorination - Canada.ca
2004 article from Health Canada and the Public Health Agency of Canada. Chlorine is a disinfectant added to drinking water to reduce or eliminate microorganisms, such as bacteria and viruses, which can be present in water supplies. The addition of chlorine to our drinking water has greatly reduced the risk of waterborne diseases.
The day-to-day responsibility of providing safe drinking water to the public generally rests with the provinces and territories, while municipalities usually oversee the day to day operations of the treatment facilities. Health Canada's Water and Air Quality Bureau plays a leadership role in science and research.

Guidelines for Canadian Drinking Water Quality - Summary
Drinking water treatment devices are also an effective option. I: Magnesium (1978) None required: None: Naturally occurring (erosion and weathering of rocks and minerals) No evidence of adverse health effects from magnesium in drinking water, therefore a guideline value is not necessary. No additional comments: P: Malathion (1986, 2005) 0.19: None

- What is polyacrylamide (PAM)?
- Explore the versatile world of Polyacrylamide (PAM), its synthesis, properties, uses across various industries, and safety concerns. Polyacrylamide, often abbreviated as PAM, is a synthetic high molecular weight polymer with a significant role in several industries. It is composed of acrylamide monomers, hence its name.
- Why is polyacrylamide a versatile polymer?
- Versatility: The physical properties of PAM can be altered by changing the polymerisation process. This means that by varying the degree of polymerisation or crosslinking, PAM can be tailored to specific needs, resulting in diverse forms and uses. Polyacrylamide has found extensive use in several sectors due to its unique properties.
- What are the properties of polyacrylamide?
- Several properties make polyacrylamide a crucial compound in various applications. These include its high water solubility, ability to form gels, and its versatility in changing its physical properties through modifications in the polymerisation process.
- What is hydrolyzed polyacrylamide (HPAM)?
- Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.
