Abstract: Changes in chlorine residual concentrations in water distribution systems could be used as an indicator of microbial contamination. Consideration is given on how to model the behavior of chlorine within the distribution ...

Abstract: Bromide concentrations have been changing in rivers in Pennsylvania. Elevated bromide in source waters at drinking water treatment plant intake locations is expected to increase the formation and bromine incorporation of ...

Abstract: A water distribution system was analyzed for optimal sensor placement based on different intrusion scenarios and optimization criteria. The spatial distributions of the selected sensor networks were analyzed and compared ...

Abstract: Fossil fuel extraction activities generate wastewaters that are often high in total dissolved solids (TDS) and specific constituents that can affect drinking water, if these wastewaters enter surface waters. Control of TDS ...

Abstract: In this study, a modification is proposed to the Soil and Water Assessment Tool (SWAT) to enable identification of areas where the implementation of best management practices would likely result in the most significant ...

Abstract: The present work is the first to examine temporal variability of bacterial diversity in a free-chlorinated drinking water distribution system over multiple years. The authors examined seasonal and monthly bacterial diversity ...

Abstract: Polychlorinated biphenyl (PCB) contamination in the United States is predominately from commercially manufactured Aroclor mixtures. These mixtures consist of approximately 150 congeners and are characterized by chlorination ...

Abstract: Temporal variability in water quality sampling can lead to under or overestimation of pollution. More frequent sampling during times of expected high variability can reduce temporal bias. However, bacterial indicator ...
