Hi Joice,

In the European union we have the european water framework directive (2000) for surface water.

Hi Joice

The Australian National Guidelines (for ecosystems, drinking water, primary industries etc) can be found at the following (scroll down for links to individual documents)

We also have individual State and even local/regional guidelines for protection of freshwater and marine ecosystems. See for example the Queensland water quality guidelines which you can find a link to on this page

This is a nice dataset that I use for this kind of information. I hope it helps!
