Stochastic Analysis of Reactive Transport

Researcher: Thomas Harter


Paralleling my efforts to create projects that would generate scientific field data describing the fate and transport of nonpoint source contaminants in soil and groundwater, I have been involved in developing and synthesizing mathematical concepts and models that explicitly account for spatial and temporal variability of physical and chemical processes we measure in our field projects. The natural variability in the sediments that make up California's aquifers can be tremendous. It has significant impact on the distribution, travel time, and fate of contaminants. Using the data obtained from the field, these models are capable not only of giving better estimates of the future fate of nonpoint source contaminants, but also allow us to quantify estimates of the uncertainty associated with assessing the fate of contaminants.
