Interests and Research:
In Situ Aquifer Characterization Technologies. Research aimed at developing novel in situ aquifer characterization technologies focuses on the single-well "push-pull" method, which consists of the controlled injection of a prepared test solution into a single well followed by the extraction of the test solution/groundwater mixture from the same well. Within the aquifer, reactive components of the test solution are converted to products by various physical, chemical, and microbiological reactions. By measuring the concentrations of all solutes during the extraction phase, the mass of reactant consumed and product produced and reaction rates can be computed. The test is being applied at a variety of contaminated sites to study and quantify in situ microbial metabolic processes, sorption and ion exchange reactions, NAPL dissolution and mobilization, and heavy metals solubilization and mobilization. Dr. Istok is also affiliated with the Western Region Hazardous Substance Research Center.
 
Teaching:
Dr. Istok is a groundwater hydrologist who specializes in the development and validation of flow and contaminant transport models in laboratory and field experiments. Dr. Istok designed the large-scale physical aquifer models in the Groundwater Research Laboratory and has developed several new single well tests for aquifer characterization. He is the author of two widely used textbooks (Aquifer Testing: Analysis and Design of Pumping and Slug Tests, and Groundwater Modeling by the Finite Element Method).
