Drinking Water and Your Health

In Canada, we are fortunate to have access to drinking water that is generally of very high quality. That said, no naturally-occurring water is 100% pure. Water picks up minerals and contaminants found in the soil or deposited from the air. It is disinfected to kill harmful bacteria and other microorganisms. And, because water is a very effective solvent, it can leach metals and other substances out of the materials it comes into contact with in the municipal distribution system and in your home.

Municipal drinking water supplies

If you are like most Canadians, you receive treated drinking water from your municipal supplier. The quality of this drinking water is monitored according to the requirements of your provincial or territorial drinking water authority. If you have specific questions about the quality of the drinking water in your community, the best place to start is with your municipality. For information on how drinking water is regulated in your province or territory, check with the agency responsible for drinking water issues.

Private drinking water supplies

If you get your drinking water from a well located on your own private property, it is likely that you are responsible for making sure it is safe to drink. Well water should be tested periodically to confirm it is safe. More information on testing private wells is available from your provincial/territorial department of health or of environment.
