Decisions for environmental contamination problems are often complex due to the need to incorporate many differing measures and views. Strategies to support these decisions with a more systematic framework have evolved along with the development of computer capabilities and analytical tools. The decision process often involves incorporating subjective judgment that reflects public and stakeholder values, while also accounting for cost-benefit, toxicological health risk, and ecological risk assessment methods, along with methods to combine each of these measures. DECERNS (Decision Evaluation for Complex Environmental Risk Network Systems) has been developed as integrated decision support software for environmental problems. This tool combines multi-criteria decision analysis (MCDA) with geographic information system (GIS) components to frame practical solutions. By also incorporating cost/benefit and risk assessment tools into a common web-based platform, DECERNS permits an integrated analysis that frames effective environmental decision making.
