      I don’t think it will happen in my lifetime! Unfortunately its a MASSIVE task because of the amount of pollution we’ve allowed into the water already. I think the best way to combat the problem is to approach it in two ways. Firstly, water can be cleaned at the point of use (like your house tap) and secondly it can be cleaned at the source of the pollution – preventing it going in the water to start with. Unfortunately the first one means the environment still suffers whilst the second doesn’t combat contamination already out there – so you need both. It’ll take YEARS but you have to start somewhere. 🙂
