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.
