Any help/advice greatly appreciated please - I've read in a number of books and heard the comments in Up Close and Personal - Part 2 about the impact on rivers and more to the point fishing following gritting and wash off into the rivers after rain.
How long before the impact of the salt washing into the river wears off? is it day's/weeks? - sorry if my question is akin to "How long is a piece of string?"

PS: I don't need to know about the string
