Thirteen papers from the September 2001 NATO workshop are presented by Ray (civil and environmental engineering, U. of Hawaii at Manoa). Scientists from academia, research stations, and water utilities convened in order to explore the role of hydrogeological and well construction factors in the development of redox zones at bank filtration sites, their impacts on contaminant removal, mechanisms of pathogen removal, and the status of riverbank filtration processes in a number of countries.

Riverbank filtration is widely used in Europe and to some extent in the United States for the public water supply. It is a cost-effective and realisable treatment technology in which horizontal and vertical wells pump a mixture of ground water and induced surface water from a river. This book describes the biogeochemical issues involved in contaminant removal from surface water and the mechanisms of pathogen removal. Specifically, the following three points are considered:
*The role of hydrogeological and well construction factors in the development of redox zones at bank filtration sites and the resulting impacts on contaminant removal.
*The mechanisms of pathogen removal, including the processes, colloid filtration, die-away, decay, and predation.
*The status of riverbank filtration processes in NATO partner countries.
