This study evaluates the suitability of the hydrogeochemical computer modeling codes balance, MINTEQA2, PHREEQE, WATEQF, and WATEQ4 to the task of modeling post-mining pit water geochemistry. The advantages and disadvantages of these codes are discussed and considered in regard to their utility for pit water modeling. The report provides detailed descriptions of the operation of each software code. Chapter 2 contains a detailed discussion of introductory aqueous geochemistry and how the concepts are integrated into chemical models. Data from the cortez mine, a carbonate-hosted, open pit, precious metal mine in Nevada, are used in an inverse model to determine geochemical mass transfer that has occurred between the mine wallrock and the pit lake. These results guide the development of a forward reaction path model that may be used for future mine sites.
