What is the pH Level of Water? For Tap Pure or Filtered Water

Pure ,water, is characterized by the quality and level of the impurities found in the ,water,. For ,water, to become legally defined as “,purified water,,” ,water, impurities should be reduced to an extremely low level if not removed at all costs. The impurity level of dissolved solids in the ,purified water, must not be above 10 parts-per-million. If the ,water, meets this limit inherently has a higher purity than tap ,water,, filtered ,water, or even spring ,water,.
