WebThe Natural pH of Groundwater. The pH is a measure of the acidity of groundwater: the lower the pH, the more acidic is the water. At the typical temperature of groundwater, a pH of 7 is considered neutral. Therefore, a pH less than 7 is acidic and a pH greater than 7 means the water is alkaline. The pH is actually a measure of the hydrogen ion ... WebIn groundwater systems, pH is initially established as meteoric water comes into equilibrium with atmospheric carbon dioxide (Langmuir, 1997). This results in the formation of diprotic carbonic acid (a diprotic acid yields two H + ions per acid molecule), which subsequently undergoes dissociation to form first bicarbonate and then carbonate. As the first …
