A Tale of Two Treatments: The Multiple Barrier Approach to Removing Chemical Contaminants During Potable Water Reuse

Urs von Gunten

In response to water scarcity and an increased recognition of the risks associated with the presence of chemical contaminants, environmental engineers have developed advanced water treatment systems that are capable of converting municipal wastewater efflu ...

Surface water treatment by UV/H2O2 with subsequent soil aquifer treatment: impact on micropollutants, dissolved organic matter and biological activity

Urs von Gunten

Because organic micropollutants (MP) are frequently detected in river waters that are used as drinking water sources, combining a relatively cost-efficient natural treatment with upstream advanced oxidation processes (AOP) appears promising for their effic ...

Rainfall as a driver of epidemic cholera: Comparative model assessments of the effect of intra-seasonal precipitation events

Andrea Rinaldo, Francisco Javier Perez Saez, Joseph Chadi Benoit Lemaitre, Damiano Pasetto

The correlation between cholera epidemics and climatic drivers, in particular seasonal tropical rainfall, has been studied in a variety of contexts owing to its documented relevance. Several mechanistic models of cholera transmission have included rainfall ...

Stability of spatial patterns in water chemistry across temperate ecoregions

Camille Roland Marie Minaudo

Human activity has polluted freshwater ecosystems across the planet, harming biodiversity, human health, and the economy. Improving water quality depends on identifying pollutant sources in river networks, but pollutant concentrations fluctuate in time. Co ...

Inactivation of waterborne viruses by ozone: Kinetics and mechanisms

Camille Wolf

The growing world population, in conjunction with climate change, cases the global water de-mand to increase. It is, therefore, crucial to protect existing water resources from chemical pollution and contamination by pathogens. An increasingly popular stra ...

The Demographics of Water: A Review of Water Ages in the Critical Zone

Paolo Benettin

The time that water takes to travel through the terrestrial hydrological cycle and the critical zone is of great interest in Earth system sciences with broad implications for water quality and quantity. Most water age studies to date have focused on indivi ...

Effect of μM Fe addition, mild heat and solar UV on sulfate radical-mediated inactivation of bacteria, viruses, and micropollutant degradation in water

César Pulgarin, Luiz Felippe De Alencastro, Stefanos Giannakis, Dominique Grandjean

In this work, solar disinfection (SODIS) was enhanced by moderate addition of Fe and sodium perox- ydisulfate (PDS), under solar light. A systematic assessment of the activating factors was performed, firstly isolated, then in pairs and concluded in the co ...

Sunlight-mediated inactivation of health-relevant microorganisms in water: A review of mechanisms and modeling approaches

Tamar Kohn, Krista Rule Wigginton, Yang Liu

Health-relevant microorganisms present in natural surface waters and engineered treatment systems that are exposed to sunlight can be inactivated by a complex set of interacting mechanisms. The net impact of sunlight depends on the solar spectral irradianc ...

Cascaded amplifying circuits enable ultrasensitive cellular sensors for toxic metals

Sebastian Maerkl, Francesca Volpetti, Ekaterina Emilova Petrova

Cell-based biosensors have great potential to detect various toxic and pathogenic contaminants in aqueous environments. However, frequently they cannot meet practical requirements due to insufficient sensing performance. To address this issue, we investiga ...
