The Alberta Centre for Toxicology tests drinking water to make sure it’s safe to drink. They use the
Guidelines for Canadian Drinking Water Quality set by Health Canada to report levels of chemicals in your drinking water, including those that can be harmful to your health. To understand your drinking water chemical test results, use the information below.
Depending on the chemical, the guidelines that are used to test your water can be based on health and safety (maximum acceptable concentration) or effects like taste and smell (aesthetic objective).
If you have any questions about your drinking water test results, contact Alberta Health Services
Environmental Public Health.
Talk to your doctor if you have questions about chemicals in your drinking water and if they could affect your health.
