Webb6 mars 2024 · U.S. EPA water quality criteria for pH in freshwater suggest a range of 6.5 to 9. Fluctuating pH or sustained pH outside this range physiologically stresses many species and can result in decreased reproduction, decreased growth, disease or death. This can ultimately lead to reduced biological diversity in streams. Webb30 juli 2013 · Bottled drinking still water had pH between 6.9 and 7.5 while the sparkling type had pH between 4.9 and 5.5.

Acidic water is any water with a pH (potential of hydrogen) of 6.5 or less on a scale from 0 to 14, with 7.0 being neutral. Ideally, your drinking water should be neutral, but more often than not, this is not the case.
