Uptake without inactivation of human adenovirus type 2 by Tetrahymena pyriformis ciliates

Human adenoviruses are ubiquitous contaminants of surface water. Indigenous protists may interact with adenoviruses and contribute to their removal from the water column, though the associated kinetics and mechanisms differ between protist species. In this ...

Mechanistic insights on interactions of dissolved organic matter with chemical oxidants: quantification of reactive sites and identification of oxidation byproducts

Joanna Maria Houska

Chemical oxidants including ozone (O3), chlorine (HOCl/OCl-) and chlorine dioxide (ClO2) are applied for disinfection of drinking water. To cope with water scarcity and the increased risks associated with the presence of micropollutants, water treatment sy ...

Efficacy and health benefits of different water distribution systems in informal settlements: a cross-sectional study in Nairobi, Kenya

Jérôme Chenal, Vitor Pessoa Colombo, Jürg Utzinger

Access to safe water sources, whenever needed, is a human right. However, attending to this fundamental right remains challenging in informal settlements. Consequently, these settlements are more exposed to risk factors of several diseases related to the l ...

Global sensitivity analysis of environmental, water quality, photoreactivity, and engineering design parameters in sunlight inactivation of viruses

Tamar Kohn, Xinyi Zhang

Sunlight-mediated inactivation of microorganisms is a low-cost approach to disinfect drinking water and wastewater. The reactions involved are affected by a wide range of factors, and a lack of knowledge about their relative importance make it challenging ...

Resolving biogeochemical processes in lakes using remote sensing

Alfred Johny Wüest, Damien Bouffard, Theo Baracchini, Vincent Maurice Nouchi

Remote sensing helps foster our understanding of inland water processes allowing a synoptic view of water quality parameters. In the context of global monitoring of inland waters, we demonstrate the benefit of combining in-situ water analysis, hydrodynamic ...

Effects of groundwater on desalinization in coastal reservoir and adjacent aquifer

David Andrew Barry, Jing Xu

Coastal reservoir provides the additional storage capacity of freshwater in coastal zone which greatly alleviate the water shortage in stressed areas, and the salinization of reservoir water degrade the utility of coastal reservoir. Salinization may result ...

Pepper mild mottle virus as a water quality indicator

Pepper mild mottle virus (PMMoV) was recently found to be the most abundant RNA virus in human feces, and is a plant virus belonging to the genus Tobamovirus in the family Virgoviridae. When in human feces, it is of dietary origin from peppers and their pr ...

Behavior of NDMA precursors at 21 full-scale water treatment facilities

Urs von Gunten

A source-to-tap evaluation of the origin and fate of chloramination N-nitrosodimethylamine (NDMA) precursors at 21 full-scale drinking water plants was conducted. Upstream wastewater discharges accounted for (on a median basis) similar to 16 ng L-1 NDMA fo ...

White Paper on the Application of Molecular, Spectroscopic, and Other Novel Methods to Monitor Pathogens for Potable Reuse

Tamar Kohn, Krista Rule Wigginton, Brian Pecson

Direct potable reuse (DPR) is gaining interest in water-scarce and water-conscious regions of the world as a technology capable of treating domestic wastewater to potable water standards. Because wastewater is the source water of such treatment schemes, th ...
