For an accurate answer, your question needed some more information; such as, is it city water? and if it is a city does the water come from wells or stream diversions. Is it your own well water or water from a group of houses, like one well for 70 homes. What area is your water from. If mountains it could contain uranium, and that is bad. If prairie, it could contain arsenic, also bad. Does your local EPA office have your water on file so you can read what is in it?
By the way, just so you know, home and city water are regulated far more than bottled water. Chlorine kills bacteria. Salt based conditioners remove pollutants, bacteria and viral contaminants.
