GIS based decision support tool for remediation technology selection

Development and use of remediation technologies for contaminated soils and water progresses at a very fast pace and thus a large number of cleanup alternatives emerge. The selection of the most appropriate Remediation technology for the given site must be based on many, usually conflicting, criteria. To successfully apply all these criteria a multicriteria decision support system (DSS) is needed. Such a system must have access to data from evaluation of remediation technology performances according to all given criteria. As the managing of all environmental data is usually accomplished with a Geographical Information Systems (GIS) it is the most suitable environment for an environmental multicriteria DSS. We will present one multicriteria DSS which is integrated into the GIS platform in order to make the appropriate decision making possible directly from GIS environment.
