Chemical Testing: River Monitoring

From the earliest days of its oldest predecessor, the St. Clair River Research Committee, the SLEA has monitored the quality of Sarnia-Lambton’s largest watercourse.

At the beginning of the monitoring program, in the early 1950s, the industrial co-operative applied its scientific approach to establish a long-term, water quality measuring stick. Member companies could use the annual results as a further means of assessing the effectiveness of their plant improvements. It was reasoned that, over time, continuous reductions in plant discharges to the river would be tracked through improvements to the quality of the St. Clair River.

Water Quality: Chemical Testing: River Monitoring

This monitor, fully automated, is located at Courtright. Established in 1987, it analyzes samples of river water on an hourly basis. Twenty chemical compounds are tracked; these are associated with the refining of petroleum and the manufacture of chemicals.

See the most recent Progress Technical Summary for details on Chemical Testing of river monitoring.

Biomonitoring Studies – Some Examples

No significant differences have been observed when the test populations both upstream and down have been compared. Good water quality occurs both upstream and downstream from Sarnia Lambton industries and municipalities.
