It is my understanding that the "used steam" is re-injected near where it was sourced. I could not find the depth but an email to Puna Geothermal would probably give you the answer. Since it is below the water table I do not see how it can effect the water quality. I am pretty sure that things like papaya farming and cesspools have a much more detrimental effect.
