Push-Pull Tests for Site Characterization

The push-pull test is a powerful site characterization technique that has been applied to a wide range of problems in contaminant hydrogeology. The theoretical and practical apsects of push-pull testing were initially developed to characterize groundwater acquifers but the method has now been extended to saturated and unsaturated soils and sediments as well as to surface water bodies. Dr. Istok and his collaborators have been instrumental in the development of these techniques and he is widely recognized as the world's leading expert push-pull testing. This is the only reference book available on this powerful method.

Dr. Istok is a tenured professor in the Civil Engineering Department at Oregon State University where he has taught courses in hydrogeology for the last 27 years. He began work on the push-pull test method in 1995 and has conducted hundreds of tests across the US in research funded by federal and state agencies and private industry.
