Xulchris – you will likely not find any “free market” rivers or othe public spaces that have not been polluted because that is an oxymoron. You can’t have a free market of public space, it is either private or public…and as we have seen public spaces become public dumping grounds all too often because the public stewards are poor executors of their duties. If you want to find an example of a non-polluted river with out government involvement I’d suggest looking to see if there has ever been anywhere a completely privately owned river or lake…I don’t know if such a thing exists but if it does that’s where you’ll find evidence of a private sphere unpolluted natural resource…or if polluted then remedied through private party suits.
