Asbestos-Cement Pipes and Drinking Water
Between the 1940’s and 1970’s, cement containing asbestos was used for water distribution pipes (known as A-C pipe). A-C pipe has not been installed in municipal water systems for over 50 years and it is a generally accepted practice that A-C pipe be removed and replaced during any construction that exposes these pipes that remain in the ground.
The following links provide information on asbestos in drinking water including potential methods of exposure, health risks and treatment information.

Health Canada Guidelines for Canadian Drinking Water Quality
Guidelines are established based on current, published scientific research related to health effects, aesthetic effects, and operational considerations. Guidelines (maximum acceptable concentrations or treatment goals) are based on a comprehensive review of the known health effects associated with each contaminant, on exposure levels and on the availability of treatment and analytical technologies. Aesthetic objectives (e.g., for taste or odour) are provided when they play a role in determining whether consumers will consider the water drinkable. Operational guidance values are provided when a substance may interfere with or impair a treatment process or technology (e.g., turbidity interfering with chlorination or UV disinfection) or adversely affect drinking water infrastructure (e.g., corrosion of pipes) (Health Canada, 2022).
Health Canada publishes guidelines and other information on the website Drinking water quality in Canada.

Health Canada Guidance Documents
Health Canada works with the provinces, territories and federal agencies to establish the Guidelines for Canadian Drinking Water Quality. Over the years, new methodologies and approaches have led Health Canada, in collaboration with the Federal-Provincial-Territorial Committee on Drinking Water, to develop a new type of document, guidance documents, to provide advice and guidance on issues related to drinking water quality for parameters that do not require a formal Guideline for Canadian Drinking Water Quality.
Guidance documents are developed to provide operational or management guidance related to specific drinking water-related issues (e.g., boil water advisories), to make health risk assessment information available when a guideline is not deemed necessary (Health Canada, 2020).
Guidance Documents
- Guidance on waterborne pathogens in drinking water
- Guidance on the Temperature Aspects of Drinking Water
- Guidance Document: Overview of the Microbiological Aspects of Drinking Water Quality
- Guidance on Natural Organic Matter in Drinking Water
- Guidance on the Use of Quantitative Microbial Risk Assessment in Drinking Water
- Guidance on Controlling Corrosion in Drinking Water Distribution Systems
- Guidance on Chloral Hydrate in Drinking Water
- Guidance on Monitoring the Biological Stability of Drinking Water in Distribution Systems
- Guidance for Issuing and Rescinding Boil Water Advisories in Canadian Drinking Water Supplies
- Guidance for Issuing and Rescinding Drinking Water Avoidance Advisories in Emergency Situations
- Guidance on Potassium from Water Softeners
