“…Commonly, the amount of phages is ten times higher than that of enteroviruses in environmental water samples (Savichtcheva and Okabe 2006). However, enteric viruses have been detected in water environments in the absence of somatic coliphages, and some of them may replicate in water environments (Health Canada 2012 Some studies demonstrated a better correlation of these with infectious enteroviruses and enteric viruses than somatic phages (Health Canada 2012; USEPA 2012) and significant correlations with adenoviruses in environmental waters (Wu et al 2011), although their presence does not always correlate with the occurrence of human enteric viruses (Hot et al 2003). Despite the interesting physical (size and shape) resemblance of F ?…”

The microbiological quality of recreational waters (RW) has been assessed through the use of microbial indicators. Usually, three typical fecal bacteria, namely fecal coliforms, Escherichia coli and Enterococcus spp., are deemed by legislation and regulatory agencies for routine monitoring of the fecal contamination in RW. However, these traditional indicators have some limitations, as they underestimate health risks and do not determine the sources of contamination. Currently, the increasing concern with the minimization of human health risks associated with recreational water use and the protection of water resources outweigh the actual normative perspective. The potentials and limitations of conventional and alternative fecal contamination detection systems must be carefully evaluated, taking into account the specificities of each recreational water body and the natural or anthropogenic sources of environmental variability. The careful choice of analysis for detection and quantification of indicators in the light of their potential and shortcomings is of major importance for the timely evaluation of risks and implementation of strategies that effectively protect users and preserve water quality. This paper presents a critical literature review of the traditional and innovative methodologies for the analysis of fecal indicators in recreational water and intends to discuss their contribution for the management of the microbiological quality and safety of leisure surface waters.

“…Thus, many studies have failed to show any correlation in fresh surface waters [133][134][135][136][137], marine surface water [136][137][138], and groundwater [131,139]. In contrast, other studies have shown some correlation between human viruses and F-specific phages [23,123,126,140,141] and between human viruses and somatic coliphages in surface waters [104,140,142], between enteroviruses and somatic coliphages in sludge [82], and between human viruses and both somatic and F-specific phages in surface water [78].…”

Two groups of bacteriophages that infect Escherichia coli, somatic and F-specific coliphages, have been used in academia as both fecal and viral indicators for many years. Regulatory authorities in different parts of the world are beginning to consider coliphages as indicators of water quality in a range of settings. However, issues such as their potential replication in natural water environments, the cumbersome detection and enumeration methods, a lack of definition concerning which of the two groups should be included in future regulations, and the lack of a clear correlation between coliphages and human viruses and health risks in different water settings remain controversial. This review attempts to shed some light on these contentious issues. The conclusions are that: 1) supposing that they can replicate in some natural water settings, the contribution of coliphages replicated outside the gut will not affect the numbers contributed by fecal pollution and detected by strains recommended for standardized methods; 2) there are easy, fast, and cost-effective methods that can be used in routine laboratories after a little training; 3) perhaps the best option is to determine both groups in a single step; and 4) the low correlation of coliphages with human viruses and health risks is no worse than the correlation between different human viruses.

“…Examples of some viral indicator candidates include phages of Bacteroides fragilis and coliphages (e.g., F-RNA phages) [22][23][24][25]. In addition, adenovirus, polyomavirus, norovirus, and enterovirus have been recognized as potential viral markers for human waste contamination [21,[26][27][28]. Hepatitis A and E viruses are associated with poor countries that lack sanitation and strict hygiene controls.…”

The effect of human activities on water resources has expanded dramatically during the past few decades, leading to the spread of waterborne microbial pathogens. The total global health impact of human infectious diseases associated with pathogenic microorganisms from landbased wastewater pollution was estimated to be approximately three million disability-adjusted life years (DALY), with an estimated economic loss of nearly 12 billion US dollars per year. Although clean water is essential for healthy living, it is not equally granted to all humans. Indeed, people who live in developing countries are challenged every day by an inadequate supply of clean water. Polluted water can lead to health crises that in turn spread waterborne pathogens. Taking measures to assess the water quality can prevent these potential risks. Thus, a pressing need has emerged in developing countries for comprehensive and accurate assessments of water quality. This review presents current and emerging advanced techniques for assessing water quality that can be adopted by authorities in developing countries.
