Description:
Riverbank filtration (or induced infiltration) is a process in which river water passes through ground prior to its use as a drinking water supply. Alluvial aquifers that are hydraulically connected to rivers may provide an alternate source of water supply for water utilities. Riverbank filtration may provide a natural technology for many water treatment utilities in the US to meet the requirements of the upcoming Stage 2 Disinfectants/Disinfection By-Products and Long Term 2 Enhanced Surface Water Treatment Rules. European and recent US experience with riverbank filtration has shown that during infiltration and underground transport, processes such as filtration, sorption, and biodegradation produce significant improvements in raw water quality. Data are presented for study that evaluates the water quality improvements through riverbank filtration for three Midwestern sites.
