Determination of Haloacetic Acids in Drinking Water According to EPA Method 552.3 using Hydrogen Carrier Gas
Haloacetic acids (HAAs) are known carcinogens that may occur as disinfection byproducts in drinking water. Currently five HAAs are regulated under the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR) and occurrence of four more HAAs is being monitored under the Unregulated Contaminant Rule 4 (2018-2020) 1. Whether the targets are HAA5 or HAA9, this analysis will continue to be ...

Application of an Interactive Water Simulation Model in urban water management: a case study in Amsterdam
Water simulation models are available to support decision-makers in urban water management. To use current water simulation models, special expertise is required. Therefore, model information is prepared prior to work sessions, in which decision-makers weigh different solutions. However, this model information quickly becomes outdated when new suggestions for solutions arise and are therefore ...

Is strategic asset management applicable to small and medium utilities?
Urban water infrastructures provide essential services to modern societies and represent a major portion of the value of municipal physical assets. Managing these assets rationally is therefore fundamental for the sustainability of the services and to the economy of societies. “Asset Management” (AM) is a modern term for an old practice—assets have always been managed. In recent ...

On the political sideline? The institutional isolation of donor organizations in Jordanian hydropolitics
Fresh water availability is very low in Jordan. Current water usage is unsustainable and structures of water resource governance are inadequate. Drawing on expert interviews and the analysis of media texts, this study shows that patterns and privileges of water consumption sustain specific political and social orders, aggravating Jordan's suboptimal water resource deployment. Many of ...

Decision making and technology selection in water (reuse) applications
In recent years, a large number of developed countries have considered water reuse schemes as a mandated alternative water resource to tackle water scarcity. With increasing knowledge on and understanding of the merits of water reuse in developing communities, a number of planned water reuse schemes have also been established (Chen et al., 2012; Fatta-Kassinos et al., 2011a). The range of water ...
