Water Quality Monitoring

Long-term water quality monitoring is essential to establishing reliable water quality baselines and changes over time and in assessing the effectiveness of targeted implementation projects. Engaging stakeholders in private or public water quality monitoring opportunities educates and promotes watershed stewardship. It is also important for publicly available water quality parameters to be accessible to the public, and in a user-friendly format. Public and private stakeholders ranked water quality monitoring as the highest priority for the English River Watershed Management Authority.
