Soil column tests and chemical analyses of water samples from the Roswell ground water basin indicate that water is saturated with calcite before entering the aquifer. It is postulated that calcite precipitation and dissolution occurring within the aquifer result from nonlinear mixing effects. Four such effects are developed and applied to the Roswell ground water basin. One result is that mixing caused by leakage from the unconfined to the confined aquifer is clogging the confined aquifer with a calcite precipitate.
