I have a friends who's daughter has a copper sensitivity. Dont know why it just is. The Doctor told her that she cannot go into swimming pools because of the copper in the water will be absorbed by her body and it is bad for her.
So I told my friend that the only way that copper can get into the water is for it to leach into it from a heater core, or by using copper based agecides.
My questions is 2 fold.
Was I right with that assumption? And is there any other way for copper to get into the water, and how does he get it out?
I ask as he has a soft sided pool that he wants to put up next year, and asked my advice on how to get water that has no copper in it so that his daughter can swim in it.
