Cessna, who still works a day or two per week at the National Hydrology Research Centre in Saskatoon, said the federal government monitors a handful of rivers that cross provincial borders for things such as heavy metals, nutrients and pesticides.

As well, there are research programs that monitor certain industries and contaminants, such as pollution from the oilsands.

However, Environment Canada doesn’t have a consistent program to monitor prairie surface waters for ag chemicals.
