| Description | WATEQ4F is a program for the calculation of chemical equilibrium in natural waters. It models the thermodynamic speciation of major and important minor inorganic ions and complex species in solution for a given water analysis and in situ measurements of temperature, pH, and redox potential. From this model the states of reaction of the water with solid and gaseous phases are calculated. The examination of reaction states may suggest the origin of the dissolved constituents and assist in the prediction of the chemical effects of ground-water production, recharge, irrigation, and anorganic pollution. The original version (WATEQ) was written in 1973 by A.H. Truesdell and B.F. Jones in PL/1. WATEQ4F is the latest version of WATEQ and includes several revisions to the thermodynamic data base including the addition of selenium and uranium species as well as the recently published values of Nordstrom and others (1990). |
