Saint Lawrence River Basin Long-term Water Quality Monitoring Data

Saint Lawrence River Basin Long-term Water Quality Monitoring Data Long-term freshwater quality monitoring data for over 40 sites in the St. Lawrence River basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) as well as through the Canada-Quebec Water Quality Monitoring Agreement and the St. Lawrence Action Plan to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track the effectiveness of remedial measures and regulatory decisions. Data for sites operated by the province are available from Quebec's Sustainable Development, Environment and the Fight against Climate Change Ministry.
