E-coli-MS2 bacteriophage interactions during solar disinfection of wastewater and the subsequent post-irradiation period

César Pulgarin, Anna Carratala Ripolles, Stefanos Giannakis

In this study, the effect of MS2 bacteriophage on the inactivation of its Escherichia coli host was evaluated in an effort to recreate some the main factors governing solar disinfection of wastewater (namely microbial growth, infection, photonic flux). As ...

Seasonal and spatial variation in total trihalomethane formation potential in groundwater in Tulkarm and Hebron, Palestine

Loay Awad

Water disinfection using processes such as chlorination is required to kill bacteria and harmful biological components. During chlorination, organic components in water react with chlorine, forming harmful disinfection by-products such as trihalomethanes ( ...

Adaptation of waterborne echovirus to warm habitats enhances disinfection resistance

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann

Because of their high mutation rate, enteric virus populations excreted from a host are not clonal, but rather consist of a mutant cloud with many different genetic variants. Among these variants, the susceptibility to environmental stressors (e.g., temper ...

Chemical disinfectants

Tamar Kohn, Loïc Decrey

Safe water, sanitation, and hygiene provision and promotion are critical elements of emergency response to ensure human safety, health, and dignity. Disinfectants, such as chlorine, are widely used in emergency response to treat water for drinking. However ...

Genotypic, phenotypic and mechanistic insights into viruses with resistance to common water disinfectants

Qingxia Zhong

Infectious diseases caused by waterborne viruses contribute to the global disease burden. An effective barrier to prevent the discharge of waterborne viruses is a disinfection step, yet disinfection is not always efficient at inactivating viruses. This the ...

Cross-resistance of UV- or chlorine dioxide-resistant echovirus 11 to other disinfectants

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Qingxia Zhong, Rachele Ossola

The emergence of waterborne viruses with resistance to disinfection has been demonstrated in the laboratory and in the environment. Yet, the implications of such resistance for virus control remain obscure. In this study we investigate if viruses with resi ...

Carbon, Hydrogen, and Nitrogen Isotope Fractionation Trends in N-Nitrosodimethylamine Reflect the Formation Pathway during Chloramination of Tertiary Amines

Urs von Gunten, Stephanie Spahr

Assessing the precursors and reactions leading to the carcinogenic N-nitrosodimethylamine (NDMA) during drinking water disinfection is a major challenge. Here, we investigate whether changes of C-13/C-12,H-2/H-1, and N-15/N-14 ratios of NDMA give rise to i ...

Formation of N-nitrosodimethylamine during water disinfection with chloramine

Stephanie Spahr

Disinfection processes such as chlorination, chloramination, and ozonation are a crucial measure to provide safe drinking water because they effectively inactivate pathogenic microorganisms. However, these processes can also lead to the formation of harmfu ...

Point-of-use water filters can effectively remove disinfection by-products and toxicity from chlorinated and chloraminated tap water

Urs von Gunten

Epidemiological risk estimates point toward potential health risks posed by disinfection by-products ( DBPs) in chlorinated drinking water. Point-of-use filters can effectively remove regulated DBPs from tap water but the removal of unknown DBPs and toxici ...

Sample Enrichment for Bioanalytical Assessment of Disinfected Drinking Water: Concentrating the Polar, the Volatiles, and the Unknowns

Urs von Gunten

Enrichment methods used in sample preparation for the bioanalytical assessment of disinfected drinking water result in the loss of volatile and hydrophilic disinfection byproducts (DBPs) and hence likely tend to underestimate biological effects. We develop ...
