GENERATION OF RISK MAPS OF CONTAMINATED AREAS COMBINING GEOGRAPHIC INFORMATION SYSTEMS WITH GEOSTATISTICS (original) (raw)
We present a methodology to estimate the uncertainty associated with the determination of contaminated areas requisite for the assessment and application of soil remediation techniques. This methodology uses geostatistical techniques to develop uncertainty models of contaminant concentrations. The advantage of this method is that it accounts for the ubiquitous natural uncertainty in the concentration level of a hazardous substance in the soil and it directly incorporates this uncertainty into the decision process. The method is developed in the context of Geographic Information Systems (GIS), using new routines to couple Geostatistical packages with the GIS.
