Water Comparsion

Pure water is H₂O with no other minerals or chemicals

There are various types of water -

TYPE	POSSIBLE PROBLEMS
Tap	Dirt, sodium, fluoride, iron, copper, silicon, nitrates, lots of chlorine, viruses, bacteria, chemicals, up to 500 parts per million contamination.
Spring	Same as above problems with up to 400 ppm contamination
Mineral	Also contains contaminants plus picks up the mineral or organic matter as it passes through soil and rock, usually over 500 ppm contamination.
Boiled	Inorganic minerals remain with dead germs
Rain	Picks up bacteria, dust, smoke, mud and minerals & acid rain
Filtered	Bacteria and viruses remain, filter collects decaying matter. After a few days the bacteria multiplies through the filter, causing greater contamination.
Distilled	Nothing to report!
