I presume the melting snow washes it into the waterways.

Does it measurably affect the salinity of what would be freshwater and does it affect the flora and fauna?

Could it be recovered?

I've also wondered about that and, also, about all the rubber on the roads from tyres. Where does that end up?

As you say salt dissolves in the ground water and eventually reaches the sea via the rivers. It can indeed affect flor, salt will kill many plants in high concentrations, so watch how much you throw around on your driveway if you don't want to kill your garden plants. Interestingly our roadside verges are now home to some plants previously found by the coast because they can tolerate high salt levels and councils usually plant verges with salt tolerant plants for this very reason.

Here in Lancashire, we scrape it all up and send it over to Yorkshire where they put it on their chips.

>>also, about all the rubber on the roads from tyres.

That can now be measured on plants.

We're eating the stuff!

I used to work in sewerage (so to speak) and it was well known that on highway drainage systems what was referred to as 'the first flush' ie the first rush of water through a system following a period of dry weather, would be heavily polluted, mostly with visible oils and such but I suppose there would be high salt levels too on occasions.
