Description BALANCE is an USGS program to calculate mass transfer for reactions in groundwater. Defines and quantifies reactions between groundwater and minerals. Calculates the mass transfer necessary to account for a change in composition between two water samples. Also models mixing of waters, redox reactions and isotropic composition. Runs as a batch program requiring input files prepared with the pre-processor BALNINPT, or a text editor. The pre-processor automatically accesses a chemical reaction data base, BALNINPT.DAT, included with the software. Contains source code and runtime versions. The documentation includes a description of the underlying principles and the input necessary to run the program, and three examples typical of ground-water systems. BALANCE is no longer maintained by the developers; it has been replaced by the program NETPATH.
