Mineral-saturation indices were computed using water-quality data collected from groundwater wells to determine if chemical constituents were present in sufficient concentrations to abiotically precipitate the minerals identified in SEM and X-ray analyses described in SIR 2018-5073 (Bayless and others, 2018). Mineral-saturation indices were also computed for multiple hypothetical mixtures of groundwater from EW-4B, collected on October 9, 2014, and groundwater from D40, collected on June 14, 1993, to explore the effect of over-pumping and inducing shallow, oxygenated water into the well screen on mineral precipitation. This USGS data release contains all of the input and output files for the simulation described in the associated publication (https://doi.org/10.3133/20185073).
