Water - What is it?

[biertourist]

I appreciate the vote of confidence, Will but I'm not going to be able to help out on this subject as I just don't know the answer to your question.  I've never come across this 47ppm number before nor the general idea that there's always a certain amount of permanent hardness left behind.  Let me see if I can drum up a true expert to weigh in...

The Wikipedia article seems to imply that temporary hardness (reducable by boiling or addition of lime) is chemically either calcium bicarbonate or magnesium bicarbonate while permanent hardness involves sulfate or chloride compounds. (Calcium sulfate or magnesium sulfate.)
