This project explores the policy and science behind riverbank filtration. An introduction to water resource management and risk management includes discussions of the precautionary principle as well as regulatory rationalization. Basic hydrologic principles are introduced, followed by an in-depth look at the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR), and how it affects public water suppliers using riverbank filtration as their primary filtration process. An introduction to riverbed dynamics and sediment transport is followed by a description of a field research and data analysis component of this project, relating rainfall distribution to scour at a riverbank filtration site in Harrison, Ohio. Analysis of rainfall distribution showed there to be a correlation between an anomalous scour/fill pattern at the site and the downstream-to-upstream pattern of rainfall for that specific event in March of 2006. Suggestions are made for changes to LT2ESWTR. Comparisons between riverbank filtration and traditional filtration methods reveal strong similarities. Analysis of the most recent published research on the effectiveness of riverbank filtration suggests that the prescriptive removal credit for Cryptosporidium under LT2ESWTR of 1 log may be too low. By employing the concept of regulatory rationalization, it is suggested that the presumptive treatment credit regulations become suggested guidelines and that there be a push for more local decision making in regards to drinking water filtration methods. 2007-04-27 English text Miami University Honors Theses / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=muhonors1177554944 http://rave.ohiolink.edu/etdc/view?acc_num=muhonors1177554944 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
