Throughout the United States increasing demands for safe drinking water and requirements to maintain healthy ecosystems are leading policy makers to ask complex social and scientific questions about how to assess and manage our water resources. This challenge becomes particularly difficult as policy and management objectives require scientific assessments of the potential for ground-water resou...

Seven alternatives were evaluated to determine the most effective water supply strategy for the United Stares Marine Corp Air Station at the New River Water Treatment Plant, Camp Lejeune, North Carolina to ensure adequate flow, pressure and quality of potable water. It was determined that the No Action alternative was not acceptable due to plant deficiencies that have caused regulatory complian...

It is widely recognized that food consumption patterns significantly impact water requirements. The aim of this paper is to quantify how food consumption patterns influence water requirements in China. The findings show that per capita water requirement for food (CWRF) has increased from 255 m3 cap−1y−1 in 1961 to 860 m3 cap−1 y−1 in 2003, largely due to an increase in the consumption of animal...

Degradation of acrylic water base color from synthetic wastewater by the Fenton process was performed. Experiments were conducted on the sample containing 100 and 400 mg/l of Acrylic water base color. The study was performed for searching optimum values of FeSO4 and H2O2 concentration, pH and temperature. The H2O2 requirement seems to be re...

With more than a billion people lacking accessible drinking water, there is a critical need to convert nonpotable sources such as seawater to water suitable for human use. However, energy requirements of desalination plants account for half their operating costs, so alternative, lower energy approaches are equally critical. Membrane distillation (MD) has shown potential due to its low operating...
