ABSTRACT

The starting point for discussion of reactive zone strategies is an examination of the physical and chemical compartmentalization of contaminants and the migratory processes that extend the distribution of contaminants beyond their source areas, generating the large-scale, persistent distributions of contaminants we observe in aquifers. The mechanisms that determine contaminant distribution and migration are also at work in reactive zone systems, and reactive system designs must anticipate and, where possible, exploit those forces to be effective.
