Quality of river water? What describes it?

What defines river water as having good quality? What elements affect whether it is of good quality? When does it begin to be of bad quality?

I am guessing contamination is one extreme, but I need what makes up the good extreme. Is it pH? or maybe oxygen levels? The life in it?
