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.
