Our tap water has an average of 32 ppm solids (I think that's a measure of hardness?).
Heavy metals:
1. Chromium - .003 ppm
2. Barium - .l ppm
3. Selium - .004 ppm
4. Lead - .003 ppbillion
Our chlorine content averages 0.7 ppm and our fluoride content averages 0.4 ppm
Perhaps you water quality buff/experts will tell me whether these are good numbers for using my tap water on most of the carnivores, or perhaps bad numbers. I don't really have a clue what reverse osmosis numbers would look like or for that matter, rain water. Distilling water would/should result with zero of all of these substances (I think).
