Provincial & Federal Regulations

All public drinking water systems in British Columbia must comply with the BC Drinking Water Protection Act and the BC Drinking Water Protection Regulation. In addition, while not legally required to comply with all of the water quality parameters in the Guidelines for Canadian Drinking Water Quality, many water suppliers use the Guidelines virtually as compulsory criteria that must be met if possible.

USEPA Regulations

In addition to the regulations listed above, where appropriate, CRD-operated water systems also comply with many of the United States Environmental Protection Agency (USEPA) rules and regulations on a voluntary basis. Some of the limits in the USEPA rules provide the basis for water quality treatment goals.

World Health Organization Regulations

The Province of British Columbia uses the World Health Organization limits as general reference — mostly when there is no Canadian Guideline.
