River Bank Filtration: Design, Purpose, Experience

Aired: June 19, 2013 from noon to 1pm Eastern

Induced recharge near rivers is one way to produce reliable yields in alluvial aquifer systems. This approach to groundwater extraction has many advantages and a few regulatory challenges. This webinar will discuss the history of river bank filtration (RBF) systems in the United States and in Europe and present the issues that well field developers, regulators, and design/modelers need to think about as they site and use these system for their clients. The webinar outline will be as follows:

- History of RBF
- Hydraulics of wells near rivers
- Water quality – pathogens and inorganic chemistry
- Regulatory challenges – GWUDI designation
- Evaluating impacts and yield – new tools
- Experiences and case histories
