The Grand River is running sweet.
A study done by the University of Waterloo shows concentrations of three different artificial sweeteners are the highest ever recordecd in any river, anywhere.
Samples were taken at 23 river sites between June of 2007 and April of 2009.
Among the findings: concentrations of sweetener equivalent to between 82-thousand and 189-thousand cans of diet pop flowed by one site on the river every single day.
Artificial sweeteners are widely used as a sugar substitute in foods and drink, and pass through the body and sewage treatment relatively unaffected.
Although the sweeteners are not considered toxic, there is very little research on what sort of impact they might be having on fish, plants and other wildlife in the river.
Almost a million people live in the watershed and the amount of sweetener found works out to about one-10th of one can of diet pop per person living in the watershed.
