      The drinking water distribution system is the last protective barrier before the consumers' tap. A well-maintained and operated distribution system is therefore a critical component of providing safe drinking water. This webinar will present information included in a new guidance document prepared by Health Canada in collaboration with the Federal-Provincial-Territorial Committee on Drinking Water. Information to be covered includes: the direct and indirect health effects of water quality deterioration in the distribution system; factors that contribute to water quality deterioration; monitoring methods or parameters that are available to determine if water quality changes are occurring; and strategies that can be used to manage these changes. Practical applications of the suggested guidance will also be presented by two municipalities.

      Who should attend?
      Representatives of federal, provincial and territorial environment and health agencies, local governments, drinking water suppliers, consultants, equipment suppliers, laboratory staff and other stakeholders interested in learning about drinking water distribution system biostability.
