High ph groundwater
WebRegular aluminum concentrations in groundwater are about 0.4 ppm, because it is present in soils as water insoluble hydroxide. At pH values below 4.5 solubility rapidly increases, causing aluminum concentrations to rise above 5 ppm. This may also occur at … 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 …
