If people can at all afford it, get a reverse osmosis unit for about 170.00 on Amazon. Or, at least a Berkey water filter system. The Berkey won't clean the water nearly as well and may leave key components of the vax in the water because it doesn't really remove particulate. However, the RO cleans to the micron leaving the water nearly pure H20. My tap water is around 600 parts per million. My RO is 25. People think they need the "minerals" in tap water, but they are also getting dangerous particles like high nitrates, nitrites, fluoride, chemicals and chlorine, and those outweigh the benefit of any minerals. You're better of taking electrolytes/minerals separately. If you think your bottled water is much better, think again, unless it's purified with RO.
