First, you need water anyway. Your water input comes from any water liquid. Whether it's tapwater, water from wine, water from soda, water from fruit When you check a water bottled label check for nitrates. Presence of nitrates means that the water was reached by organic matter or ferilisers. The filtering process is too short. Also temperature at spring is important, the cooler the better. Mountain water, where the water usually has a long underground stay, is the better.
PH is not that important. Our stomac has a very low PH and it's self regulating, if you drinj acid, like wine or vinegar or coke, there is less production of HCL to regulate the PH level. Unless you dring more than a coke a day PH is not important from water.
The worst water used is the one of canning industries. That is soda. It's no better than tap soda. And on tap soda you can add a filter for heavy molecules (pesticides).
Do you know where the best water comes from? wine!
Wine fermentation precipitates most of the pesticides and 95% of wine is water that was filtered by a rood system....
