Recharge waters, dissolution reactions

The results of various attempts to explain the provenance of the mature Whittle waters in terms of the above precursor waters and mineral phases are outlined below. Assuming that Whittle recharge water is the sole precursor, several attempts were made to model the evolution of the mature Whittle water by reaction of the Whittle recharge waters with various minerals. Where the mineral suite included calcite, dolomite, gypsum, pyrite and K-jarosite, but not ankerite, the resulting models were of poor credibility they invoke coupled precipitation of calcite (although dissolution is far more likely) and substantial dissolution of... [Pg.202]

H2CO3 in recharge water was made from six Rainier Mesa water samples for which reliable pH and HCO3 values were available. In simple silicate rock dissolution, all carbonate species result from reaction of H2CO3 with the rock. Thus, HCO3 + C03 + H2CO3 at any point in the flow path is assumed to be a constant. Calculations of concentrations of these species in the six samples previously mentioned allowed calculation of H2CQ3 initially available for reaction. These data are presented in Table I. The arithmetic mean was used in subsequent calculations. [Pg.777]

The chloride content of groundwater may be a sensitive indicator of either the distance between the intake area of the aquifer and coast or the amount of evapotranspiration prior to groundwater recharge. Because chloride is not normally derived from dissolution of solid aquifer materials and it does not enter into ion exchange reactions to any great extent, the chloride content in shallow aquifers and aquifers isolated from sources of connate water should reflect some of the original environmental factors of the outcrop area [19,86]. [Pg.217]
