Jonathan Istok

Jonathan Istok is a Professor and Head of the School of Civil and Construction Engineering at Oregon State University. His expertise lies in groundwater hydrology, bioremediation, and aquifer characterization. He is renowned for developing the single-well push-pull test method to quantify subsurface reactions and remediation processes. Dr. Istok’s research focuses on contaminant remediation for chlorinated solvents, radionuclides, and explosives in aquifers, combining laboratory and field experiments.

He has authored three influential books: *Push-Pull Tests for Site Characterization*, *Aquifer Testing: Analysis and Design of Pumping and Slug Tests*, and *Groundwater Modeling by the Finite Element Method*. His teaching spans groundwater hydrology, modeling, and remediation.

Research interests include microbial metabolic processes, NAPL dissolution, heavy metal mobilization, and sorption reactions. He leads the Groundwater Research Lab and collaborates on projects like the Umatilla Chemical Depot cleanup.
