Summary
We construct in this chapter reactive transport models of the mobility of heavy metals in an aquifer containing a complexing surface. The modeling shows that surface complexation can play a controlling role in the fate and transport of heavy metal contamination in the environment. Surface complexation causes not only retardation, as might be expected from simple sorption theory, but a pronounced tailing that hinders remediation by pump-and-treat methods.
