“…However, only a few samples showed E. coli together with the optical brighteners, suggesting a different fate and transport of these indicators within the aquifer (Smith et al 2014 ). In Montreal, Canada, a study applied a multiparameter source tracking toolbox combining chemical source tracking markers for sewage (caffeine, theophylline, and carbamazepine) together with the human-associated genetic markers HF183 and mitochondrial DNA to detect illicit wastewater discharges into storm sewers during dry weather (Hachad et al 2022 ). The authors used a composite index of the different markers together with the levels of E. coli to identify household cross connections or indirect illicit discharges and verified them successfully with dye tracing.…”

The impacts on faecal pollution analysis using nucleic acid-based methods, such as PCR and sequencing, in health-related water quality research were assessed by rigorous literature analysis. A wide range of application areas and study designs has been identified since the first application more than 30 years ago (>1,100 publications). Given the consistency of methods and assessment types, we suggest defining this emerging part of science as a new discipline: genetic faecal pollution diagnostics (GFPD) in health-related microbial water quality analysis. Undoubtedly, GFPD has already revolutionised faecal pollution detection and microbial source tracking, the current core applications. GFPD is also expanding to many other research areas, including infection and health risk assessment, evaluation of microbial water treatment, and support of wastewater surveillance. In addition, storage of DNA extracts allows for biobanking, which opens up new perspectives. The tools of GFPD can be combined with cultivation-based standardised faecal indicator enumeration, pathogen detection, and various environmental data types, in an integrated data analysis approach. This comprehensive meta-analysis provides the scientific status quo of this field, including trend analyses and literature statistics, outlining identified application areas, and discussing the benefits and challenges of nucleic acid-based analysis in GFPD.

“…60,71 Studies have demonstrated the utility of sourcetracking human fecal pollution signatures in storm drainage networks in order to pinpoint these sources of sewage pollution. 58,68 A. butzleri was also detected in samples that lacked detection of source tracking markers for human sewage, and the lower effect size (φ < 0.4, see Tables S9 and S10, Supporting Information File 1) of the significant relationship between A. butzleri and HF183 reflected the fact that other animal reservoirs may also contribute A. butzleri loading into stormwater drainage systems. 12−16 Important animal host reservoirs of A. butzleri that may be pertinent to urban stormwater drainage include dogs, 15 geese, 12 and cats.…”

A. butzleri is an underappreciated emerging global pathogen, despite growing evidence that it is a major contributor of diarrheal illness. Few studies have investigated the occurrence and public health risks that this organism possesses from waterborne exposure routes including through stormwater use. In this study, we assessed the prevalence, virulence potential, and primary sources of stormwaterisolated A. butzleri in fecally contaminated urban stormwater systems. Based on qPCR, A. butzleri was the most common enteric bacterial pathogen [25%] found in stormwater among a panel of pathogens surveyed, including Shiga-toxin producing Escherichia coli (STEC) [6%], Campylobacter spp. [4%], and Salmonella spp.[<1%]. Concentrations of the bacteria, based on qPCR amplification of the single copy gene hsp60, were as high as 6.2 log 10 copies/100 mL, suggesting significant loading of this pathogen in some stormwater systems. Importantly, out of 73 unique stormwater culture isolates, 90% were positive for the putative virulence genes cadF, ciaB, tlyA, cjl349, pldA, and mviN, while 50−75% of isolates also possessed the virulence genes irgA, hecA, and hecB. Occurrence of A. butzleri was most often associated with the human fecal pollution marker HF183 in stormwater samples. These results suggest that A. butzleri may be an important bacterial pathogen in stormwater, warranting further study on the risks it represents to public health during stormwater use.

“…Thus, urban stormwater pipes have become the input sources of contaminants (DOM and hazardous DBPs) to natural water due to illicit connection of sewage pipes. Previous studies have focused on the diagnosis of pipe illicit connections (Xu et al, 2021), the location of illicit discharges (Hachad et al, 2022), the runoff quality dynamics (Regier et al, 2020), the nitrogen transport and sources in urban stormwater (Wang et al, 2022) and the management of urban stormwater (Marazuela et al, 2022;Rentachintala et al, 2022). However, little is known about the impacts of illicit connection on the characteristics of DOM and the output level of DOM in urban stormwater systems.…”
