Abstract Water Treatment is defined as the selection of sampling sites and sampling frequency to determine physical, chemical, and biological properties of water. The main approaches to water treatment were identified as hydrogeologic and statistical. The various methods available in the hydrologic literature have been evaluated by considering the spatial scale of the monitoring program, the objective of sampling, data requirements, temporal effects, and range of applicability. Considerable advance has been made over the last two decades that now permit the application of methodical and testable approaches to water quality monitoring, design riverbank filtration, although they mostly serve for preliminary analysis and design. The main goal of these studies was to characterize the ability of riverbank filtration to provide a cost-effective, stand alone pretreatment for filter- media technologies. Results indicate that the use of riverbank filtration can reduce membrane treatment costs by 10-20 percent. In addition, overall recommendations were developed to help other utilities evaluate this technology as a potential lower cost alternative for minimizing treatment costs. The opinion on Ground-Water Quality Monitoring Network Design is that as there continues to be advances in hydro geochemistry, ground-water hydrology, and risk and geo statistical analysis, methods for ground-water quality monitoring network design will be improved and refined, and they will become ever more useful in the important mission of water treatment.
