Context. SARS-CoV-2 wastewater-based epidemiology (WBE) has been advanced as a relevant indicator of distribution of COVID-19 in communities, supporting classical testing and tracing epidemiological approaches.Gap. Up to now, there are not many studies on a large geographical scale combining severa...

Context. Arboviruses (arthropod-borne viruses) are pathogens that impose a great social and economic burden globally. Clinical surveillance of arbovirus outbreaks is insufficient to assess the true prevalence as a large proportion of cases exhibit no or only mild clinical symptoms such as reported f...

Membrane bioreactors (MBR) have better removal of emerging organic contaminants such as antibiotics, antibiotic resistance genes (ARG) and microbial contaminants compared to activated sludge processes. In addition, anaerobic membrane bioreactors (AnMBR) have advantages over aerobic configuration as ...

Wastewater-based disease surveillance is a promising approach for monitoring community outbreaks. Here we describe a nationwide campaign to monitor SARS-CoV-2 in the wastewater of 159 counties in 40 U.S. states, covering 13% of the U.S. population from February 18 to June 2, 2020. Out of 1,751 total...

Intermittent water supply (IWS), the provision of potable water non-continuously, leads to periods of stagnation with conditions favorable for biofilm growth. Regular repressuring of pipes at the beginning of each supply cycler has been shown to shear off biofilms from pipewalls and transfer inhabit...

Context. Extracellular DNA (exDNA) is an emerging contaminant in wastewater which cannot be removed efficiently due to their small molecular size and poor settleability. Hence it can be disseminated into environment by water reuse. Gap. The movement of exDNA across wastewater treatment is unknown...

SARS-CoV-2 has genetically changed since the first infections. The quick adaption of the virus to the new host led to mutations in the binding sites of the spike protein, which is known to increase the infectivity of the virus (Korber et al., 2020). The genome sequencing of wastewater has developed ...

Several factors have been identified to play a role in enhancing extracellular DNA (eDNA) transformation by bacteria. These factors include chemical compounds such as disinfection by products (DBP) and pharmaceutical drugs; moreover, environmental stressors such as solar irradiance has been shown to...

Context. Wastewater surveillance has emerged as a useful tool in the public health response to the COVID-19 pandemic.Gap. While wastewater surveillance has been applied at various scales to monitor population-level COVID-19 dynamics, there is a need for quantitative metrics to interpret wastewater d...

High yields of agricultural produce is reached traditionally by the application of fertilizers and/or pesticides. When agricultural soil is saturated with pesticides, any pesticide addition to the soil leaches and thus reaches the underlying groundwater. Preventing further contamination and remediat...
