Comparison of TDS and Uranium Concentrations in Ralston Creek, Upstream <br />and Downstream of Waste Rock Dumps <br />(b) Geochemical Characterization of Mine Refill Water <br />Processes affecting water quality in the flooded mine were evaluated in a geochemical modeling study by <br />Whetstone Associates(2007). The study used the equilibrium-based geochemical modeling software <br />• PHREEQCi 2.14.2 and a modified MINTEQ.v4 database that contained an expanded compilation of <br />thermodynamic data for uranium and molybdenum. <br />4109C.100419 Whetstone Associates
