What are your findings, if any, and comment on the amount of salt that is used in the various cities around the great lakes whose storm water drains into them, untreated?
Growing up in Toronto, insemento notice that far more salt seems to be used today than ever before. On roads but particularly in plazas and parking lots.
I know the volume of water in the great lakes is immense but i have to imagine this is having a measurable effect.

Mike: Our group has not done research on salinization (at least to date!) but other researchers have documented that levels of road salt application are increasing. In general, road salts are washed into storm drains and the water is not treated before it enters lakes and streams.

Ty. Where's the best place to learn more about this?

Sailing on Lake Ontario outside of Toronto versus Georgian Bay you can definitely notice the difference in salinity when you get splashed by the water.
Entirely anecdotal evidence though.
