Special Issue Information

Dear Colleagues,

Microbial risk assessment (MRA) is a process used to identify, confirm and quantify hazardous outcomes caused by exposure to certain microbial factors, based on existing scientific data, as well as to describe risk characterization. MRA can also provide preventative management decisions for potential microbial safety events, with powerful integrated analytical capabilities, and has received increasing attention in the field of water environmental systems (particularly in water reuse for recreational water). Over the recent decades, as outbreaks of waterborne diseases continue to occur globally, the World Health Organization (WHO) has recommended a preventive, risk-based approach for water quality management, from the source to exposure, for the management of microbial hazards. This approach indicates that the MRA of water systems will become an indispensable development area, and will play an important role in water reuse and public health safety management. The Special Issue "Microbial Risk Assessment for Recreational Waters", published in Water, will present the latest advances in MRA in the field of water reuse, as well as the key aspects of frontier hazard identification, safety assessment and risk characterization changes and applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Global water scarcity has led to significant dependence on reclaimed or recycled water for potable uses. Effluents arising from human and animal gut microbiomes highly influence water quality. Wastewater pollution is, therefore, frequently monitored using bacterial indicators (BI). However, threats to public health arise from the frequent incidence of wastewater-mediated viral infections–undetected by BI. Moreover, the enteric viromes contaminating wastewater are characterized by high abundance, genetic diversity and persistence in various water environments. Furthermore, humans usually suffer a minimum of a single acute diarrheal episode over their lifetime arising from extraneously acquired enteric microbiomes. A wide range of management methods are employed—in particular, microbial source tracking (MST) approaches to confront infections arising from exposure to contaminated wastewater. This review elaborates the viral contamination of treated wastewater and associated public health issues. Latterly, we discuss the various management strategies of wastewater pollution using conventional fecal indicators, viral indicators and human viral surrogates, with particular interest in the pepper mild mottle virus (PMMoV). Globally, PMMoV has been detected in rivers, aquifers, irrigation systems, and coastal and marine waters at high prevalence rates and concentrations greater than 105 genome copies per liter (gc/L). PMMoV was also found in almost all untreated wastewater environments. PMMoV concentrations in wastewater vary from 103 to 107 gc/L. These values are more than the maximum recorded viral indicator concentrations in wastewater for other proposed indicators. Limited variability in the daily concentrations of PMMoV in fecal wastewater has been studied, with an estimated average concentration of 105 gc/L with insignificant seasonal variability. The information summarized in this article offers fundamental knowledge for decision making in terms of defining the suitability criteria of candidate fecal indicators, risk assessment application and efficient wastewater management.
