As a matter of interest, the biggest polluter of the Waikato river is Hamilton City, followed by farm run-off. The biggest heavy metal polluter is the Wairakei geothermal power station although I believe that this has been reduced with the implementation of condensate re-injection. Kinleith pulp and paper mill where I'm based adds minimal chemicals but does add to the colour load through tannin in the tree bark. We've substantially reduced this in recent years. I'm passionate about water quality too, being a river user.
BTW, Tainui have been involved with the river for as long as I can remember and have always been officially involved with the consultative meetings we regularly run with other stakeholders such a local authorities, Fish and Game, Greenpeace etc.
