Evaluating Remedial Alternatives for an Acid Mine Drainage Stream: Application of a Reactive Transport Model

Citation

Briant A Kimball, and Robert L Runkel, Evaluating Remedial Alternatives for an Acid Mine Drainage Stream: Application of a Reactive Transport Model: .

Summary

A reactive transport model based on one-dimensional transport and equilibrium chemistry is applied to synoptic data from an acid mine drainage stream. Model inputs include streamflow estimates based on tracer dilution, inflow chemistry based on synoptic sampling, and equilibrium constants describing acid/base, complexation, precipitation/dissolution, and sorption reactions. The dominant features of observed spatial profiles in pH and metal concentration are reproduced along the 3.5-km study reach by simulating the precipitation of Fe(III) and Al solid phases and the sorption of Cu, As, and Pb onto freshly precipitated iron(III) oxides. Given this quantitative description of existing conditions, additional simulations are conducted [...]
