Na-Ca-Cl groundwaters with salinities of 1 to 30{per thousand} discharge from natural springs and artesian wells in Mississippian carbonates and Ordovician sandstones and carbonates in central Missouri. Carbonate saturation and quartz supersaturation are maintained throughout the salinity range. Major and trace element and isotopic variations in the waters are used to place constraints on models for rock-water interaction and regional hydrology. The integration of geochemical, isotopic and hydrologic data on a local and regional scale suggests a history for the central Missouri groundwaters involving: (1) meteoric recharge in the Front Range of Colorado; (2) dissolution of Permian halite in the subsurface of Kansas; (3) interaction with predominantly silicate mineral assemblages in Paleozoic strata (and possibly Precambrian basement), with aquisition of crustal Sr and REE signatures; (4) dilution and migration to shallow aquifer levels in central Missouri; and (5) mixing with local meteoric recharge and discharge through Mississippian carbonates with no significant change of the isotopic signatures acquired in stage (3).
