According to the anaylist I recieved for the water company they don't, well
it is not listed as such anyway. The copper is low or at least I think it is
at .05 ppm. There is alot of limestone around here too and the places that
have well water have a much higher hardness than I do. I am fairly lucky in
the fact that my water comes from a small river here. The GH is 130 ppm with
a KH of 66 ppm.
