Approved Water Quality Guidelines

Ambient water quality guidelines (WQGs) are developed to promote healthy ecosystems and protect human health. Water quality guidelines are science-based levels of physical, biological and chemical parameters for the protection of water uses such as aquatic life, wildlife, agriculture, drinking water and recreation.

Approved WQGs are policy statements and applied generically province wide, providing the basis for water quality assessments and informing decision-making in the natural resource sector.
