Riverbank Filtration Understanding Contaminant Biogeochemistry and Pathogen Removal

About this book

Proceedings of the NATO Advanced Research Workshop, held in Tihany, Hungary, from 5 to 8 September 2001.

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.
