Drinking water comes into contact with many materials and additives as it moves through the purification process and distribution system. The materials and additives used can impact the final quality of the drinking water at the point of consumption. Therefore, regulating and controlling the materials and additives used is a key activity for ensuring a safe supply of drinking water.

How are Materials for Drinking Water Regulated in Canada?

In Canada, materials and additive products used in the processing and distribution of drinking water are not currently regulated at the national level. Despite this gap, many municipalities have adopted, or are planning to adopt, regulations for controlling the use of materials and additives used in the supply of drinking water.

Although materials and additives used in drinking water production and distribution are not currently regulated at the national level in Canada, Health Canada, the federal department responsible for helping Canadians to maintain and improve their health, does work with international standard-setting organizations to develop health-based standards for materials that come into contact with drinking water.

What are Health-Based Standards for Drinking Water Materials?

Materials used in the production and distribution of drinking water are essentially covered by two types of standards: health-based and installation-based. Health-based standards are designed to safeguard drinking water by ensuring the safety and performance of materials used in processing and distribution. Installation standards, such as plumbing standards, focus on the requirements for putting components and materials into place within the processing and distribution system.

Health-based standards for drinking water materials are developed primarily by NSF International/American National Standards Institute (ANSI). These standards include the NSF/ANSI 61 standard for Drinking water system components – Health effects.

What is the NSF/ANSI 61 Standard?

Developed by the National Sanitation Foundation (NSF) and the American National Standards Institute, NSF/ANSI 61 includes criteria for testing and evaluating products to ensure they do not leach hazardous contaminants into water. Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI 61 establishes minimum criteria for impurities and contaminants that may be released indirectly into drinking water from products, components and materials, including joining and sealing materials such as gaskets and seals.

What Drinking Water Applications does the NSF/ANSI 61 Standard Cover?

The NSF/ANSI 61 standard applies to materials used in the following:
