National Water Quality Monitoring

Sampling in a lakeWater quality is determined by its physical, chemical and biological characteristics. To ensure the health of aquatic ecosystems in Canada, maximum allowable limits exist for most potentially harmful contaminants. The monitoring programs of Environment Canada and its partners are designed to measure these characteristics to determine if these maximum allowable limits are exceeded.

The degradation of water bodies by human waste and industrial activities can seriously harm fish and other wildlife.

The National Water Quality Monitoring group is a distributed network of chemists, biologists and ecologists that share a common goal of protecting the health of Canada's aquatic ecosystems. With offices in several areas of the country, we implement the majority of our monitoring programs with provincial and territorial partners.
