In situ soil remediation: the reactor approach

摘要

Soil remediation is still a mystery for many decision makers, something not visible under the surface. The professionals' understanding is not yet complete, with most having only an overview of a narrow range of engineering tools used for contaminated soil. Knowledge today is not yet interdisciplinary; it mainly mirrors the attitudes of hydrogeologists. Moreover, general engineering, chemical and bioen-gineering, as well as ecoengineering, viewpoints have not yet been integrated into this knowledge. The reactor approach is an innovative classification and organization of soil remediation into a general contaminated land and soil management structure. It considers the in situ treated soil volume as the volume of a batch reactor, the groundwater flow as a flux in a flow-through reactor, etc., and establishes the (bio)engineering bases for more sophisticated and conscious remediation, with planning, execution, monitoring and evaluation (verification) processes, as is the case with other engineering disciplines.
