What's wrong with tap water?
Tap water is not automatically safe. It may be contaminated with
bacteria, viruses, protozoa, and dirt. Have your tap water tested by a
laboratory. Then ask a water company to design a filtration and
system based on the lab results. If your water comes from a well, it may
necessary to have it softened, which means eliminating hard elements like
calcium, iron, and magnesium. Water is a complex, precious substance, and
we should not take its quality or supply for granted.
