Due to rapid growth in the potable reuse industry, there is a need better characterize associated pathogen risks and degree of attenuation achieved by various treatment trains. It also important understand how emerging frameworks compare historical practice de facto reuse. As such, goals this study were (1) evaluate equivalency indirect (IPR) direct (DPR) systems; (2) alternative trains; (3) identify design components operational conditions that are most critical minimizing public health risks. To end, we developed static quantitative microbial risk assessment (QMRA) for Cryptosporidium, norovirus, adenovirus, Salmonella. Treatment process performance (including failure scenarios) resultant estimated using Stella 10.1 system dynamics model. The combined annual infection was lower DPR systems with no surface water influence [median = 1.1 × 10−8 ozone-based 3.9 10−6 reverse osmosis (RO)] compared IPR or raw augmentation (median 9.0 10−4 3.8 10−3). Although reuse, planned IPR, exceeded common benchmark, generally dominated concentrations upstream water, thereby highlighting importance source characterization all drinking systems. Moreover, calculation each often particular (e.g., adenovirus maximum 3.7 10−2 RO-based during compound failure). Sensitivity analyses demonstrated storage time temperature failures decreased greater recycled contributions (RWC) due robustness advanced and/or environmental buffer.

Abstract Purpose of Review Fecal contamination water is a major public health concern. This review summarizes recent developments and advancements in quality indicators fecal contamination. Recent Findings highlights number trends. First, continue to be valuable tool assess have expanded include able detect sources water. Second, molecular methods, particularly PCR-based advanced considerably their selected targets rigor, but added complexity that may prohibit adoption for routine monitoring activities at this time. Third, risk modeling beginning better connect human risks, with the accuracy assessments currently tied timing conditions where measured. Summary Research has although challenges remain effective use both traditional alternative characterization, source attribution apportionment, impact evaluation.

Abstract Human exposure to pathogenic viruses in environmental waters results a significant global disease burden. Current microbial water quality monitoring approaches, mainly based on fecal indicator bacteria, insufficiently capture human health impacts posed by water. The emergence of the ‘microbiome era’ and high-throughput metagenome sequencing has led discovery novel human-associated viruses, including both commensal microbiome. is often followed their detection wastewater, highlighting great diversity potentially present environment. Novel provide rich reservoir develop viral management tools with diverse applications, such as regulating wastewater reuse agricultural recreational waters. Here, we review pathway from tool, highlight select identified metagenomics subsequently detected environment (namely Bocavirus, Cosavirus, CrAssphage, Klassevirus, Pepper Mild Mottle Virus). We also discuss research needs enable application recently discovered monitoring, investigating geographic distribution, fate, viability potential viruses. Examples suggest that pathogens are likely be less abundant sewage, while other (e.g., bacteriophages or food) more but human-specific. improved resolution enabled metagenomic provides opportunity for tools.

Enveloped viruses are characterized by a lipid-containing envelope that encapsulates the virion, and they have been cause of major outbreaks pandemics. Some enveloped excreted in feces other bodily fluids infected people animals, raising question their fate aquatic environment. Consequently, we conducted systematic review meta-analysis decay rate constants (k) from 12 families (i.e., Coronaviridae, Cystoviridae (specifically Phi6), Filoviridae, Hepadnaviridae, Herpesviridae, Orthomyxoviridae, Paramyxoviridae, Pneumoviridae, Poxviridae, Retroviridae, Rhabdoviridae, Togaviridae) environmental waters wastewater to evaluate kinetics identify virus characteristics influence k. A total 812 k met inclusion criteria were identified literature, with number for each family ranging 0 560, averaged values 0.11 d–1 1.85 d–1. Virus type genus, species, subspecies, or subtype), method enumeration culture-based (RT-)QPCR), experimental water matrix type, temperature sterility found significant effects on Additionally, statistically significantly greater than nonenveloped viruses. Multiple linear regression models allow prediction log10k as function method, temperature, provided six had sufficient data available model fitting Phi6, Togaviridae). Compiled multiple can be used inform management human animal waste, operation facilities, exposure risks treatment plant workers communities living regions lack facilities. Given limited some potential water-related transmission route, there is need additional collection aid academic researchers, public health agencies, professionals involved outbreak response.

The impacts of nucleic acid-based methods - such as PCR and sequencing to detect analyze indicators, genetic markers or molecular signatures microbial faecal pollution in health-related water quality research were assessed by rigorous literature analysis. A wide range application areas study designs has been identified since the first more than 30 years ago (>1100 publications). Given consistency assessment types, we suggest defining this emerging part science a new discipline: diagnostics (GFPD) Undoubtedly, GFPD already revolutionized detection (i.e., traditional alternative general indicator/marker analysis) source tracking host-associated analysis), current core applications. is also expanding many other areas, including infection health risk assessment, evaluation treatment, support wastewater surveillance. In addition, storage DNA extracts allows for biobanking, which opens up perspectives. tools can be combined with cultivation-based standardized indicator enumeration, pathogen detection, various environmental data an integrated analysis approach. This comprehensive meta-analysis provides scientific status quo field, trend analyses statistics, outlining discusses benefits challenges GFPD.
