High ph groundwater
WebThe pH values for ground-water samples collected from these wells were very alkaline (pH = 9.6, 10.5, 11.3, and 11.7), were much higher than for similar wells completed in the … 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.

WebGroundwater is the leading international journal focused exclusively on groundwater. Since 1963, it has published a dynamic mix of papers on topics including groundwater flow and well hydraulics, hydrogeochemistry and contaminant hydrogeology, application of geophysics, groundwater management and policy, and history of groundwater hydrology. digifort cloudWebIn 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.
