Abstract
The single largest uncertainty in determining the success of remediating<br>environmental contamination problems results from inability to quantify and descrtbe the<br>natural variability within the earth --- geological, hydrological and geochemical<br>heterogeneity (Schwartz and others, 1990; Sudicky and Huyakorn, 1991). Heterogeneity IS<br>a natural result of the properties of geological materials and the processes that create and<br>modify them. It has been known for years that the single largest uncertainty in determining<br>the success of petroleum recovery is geological heterogeneity (Dickey, 1986), resulting in<br>increased emphasis on reservoir characterization (Lake and Carroll, 1986). Increased<br>emphasis on site characterization is the natural parallel attack on the problems caused by<br>heterogeneity in environmental remediation.
