AquaChem defines itself in its web site [10] as a groundwater software package featuring a
customizable database of physical and chemical parameters and a selection of analysis, calculation,
modeling, and graphing tools. This analysis tools cover a wide range of functions and
calculations used for analyzing, interpreting and comparing water quality data. This includes
simple unit transformations, charge balances, statistics and sample mixing to more complex
functions such as correlation matrices and geothermometer calculations. These analytical capabilities
are complemented by a selection of commonly used plotting techniques to represent the
chemical characteristics of aqueous geochemical and water quality data.
