Appendix:
Calcium and magnesium ions present as sulfates, chlorides, carbonates and bicarbonates cause water to be
hard. Water chemists measure water impurities in parts per million (ppm). For understandability, hardness ordi-
narily is expressed in grains of hardness per gallon of water (gpg). The two systems can be converted mathe-
matically.
