High ph groundwater
WebIt is therefore suspected that the high pHs are not representative of true aquifer conditions. Two previous studies conducted at SRP (Price, 1984; Schreeder, 1986) conclude that high pH readings in M-Area monitoring wells and Z-Area piezometers are the result of contact between groundwater and grout. Price … continued below Physical Description 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 …
