Water Quality Monitoring
Grey Sauble Conservation Authority (GSCA) collects and analyzes a wide range of local environmental data, including surface water quality, benthic macroinvertebrates, and groundwater, at monitoring sites throughout the watershed.
This ongoing monitoring helps us understand the overall health of the watershed, identify the effects of land‑use activities, and focus stewardship efforts where they will have the most impact.
“Stream bugs” are collected to help monitor changes in the biological communities of rivers over time.
Water samples are collected from sites throughout the watershed and tested for various parameters.
Groundwater wells are monitored annually to ensure groundwater levels and water quality are stable.
