Rivers are often challenged by fecal contaminations. The barrier effect of sediments against bacteria was investigated through the use a microbial source tracking (MST) toolbox, and Next Generation Sequencing (NGS) V5-V6 16S rRNA gene (rrs) sequences. Non-metric multi-dimensional scaling analysis sequences differentiated bacteriomes according to their compartment origin i.e., surface water benthic hyporheic sediments. Classification these reads showed most prevalent operating taxonomic units...
Even though organic waste (OW) recycling via anaerobic digestion (AD) and composting are increasingly used, little is known about the impact of OW origin (fecal matters food vegetable wastes) on end products’ bacterial contents. The hypothesis a predictable community structure in products according to was tested. Nine treatment plants were selected assess genetic communities found raw their content agricultural urban wastes estimate modifications through AD composting. Two main structures...
The ability of WWTP outflow bacteria at colonizing rock surfaces and contributing to the formation river epilithic biofilms was investigated. Bacterial community structures (b-) developing on rocks exposed treated wastewaters (TWW) a hospital (HTWW) domestic (DTWW) clarifier, surface waters stream located 10 m, 500 8 km from outlet, were compared. Biofilm bacterial contents analyzed by cultural approaches tpm-based DNA metabarcoding analytical scheme. Co-occurrence distribution pattern...
The hygienic quality of urban surfaces can be impaired by multiple sources microbiological contaminants. These trigger the development bacterial taxa and favor their spread during rain events through circulation runoff waters. waters are commonly directed toward sewer networks, stormwater infiltration systems or detention tanks prior a release into natural water ways. With scarcity becoming major worldwide issue, these runoffs representing an alternative supply for some usage like street...
Combined sewer overflows (CSO) are used to avoid overloading unitary sewers and wastewater treatment plants. Following the European Council Directive on Urban Wastewater Treatment (UWT), CSO discharges regulated using guidelines that aim reduce their ecological impact aquatic systems. A model CSO, which is part of a long-term experimental field observatory, was modified according these evaluate benefits compliance through analyses bacteriological chemical states receiving intermittent...
Abstract. The invasion of aquifer microbial communities by aboveground microorganisms, a phenomenon known as community coalescence, is likely to be exacerbated in groundwaters fed stormwater infiltration systems (SISs). Here, the incidence this increased connectivity with upslope soils and impermeabilized surfaces was assessed through meta-analysis 16S rRNA gene libraries. Specifically, DNA sequences encoding V5-V6 regions from free-living attached bacteria (i.e., water biofilm samples) were...
Abstract Faecal indicator bacteria (FIB) and bacterial pathogens from combined sewer overflow (CSO) in peri‐urban streams represent a major public health concern worldwide. In this study, the relationships between hydrological regime loads persistence of CSO‐borne contaminants among benthic sediments small stream were explored. Combined events their impact on sediment layers at short distance CSO monitored. Concentrations Escherichia coli (EC) intestinal enterococci (IE) two pathogens,...

The invasion of aquifer microbial communities by aboveground micro-organisms, a phenomenon known as community coalescence, is likely to be exacerbated in groundwaters fed stormwater infiltration systems (SIS). Here, the incidence this increased connectivity with upslope soils and impermeabilized surfaces was assessed through meta-analysis 16S rRNA gene libraries. Specifically, free-living attached bacteria (i.e., water biofilm samples) were characterized upstream downstream SIS,...
Stormwater runoffs are loaded with metals, PAHs, pesticides and pathogenic bacteria, conveyed for many in particulate form. One of the techniques used to manage this contaminated stormwater is use retention basins order allow settling suspended solids. The deposits thus set up represent zones contamination a particular waste. constituted waste that must be managed. objectives paper are: i) characterize sediments basin, ii) identify variability heterogeneity its microbiological, physical,...
<p>The extension of urban and peri-urban areas the related artificialization soils drastically impacts water cycle as well biogeochemical cycles. In particular, sealing with impervious surfaces such roads increases runoff decreases concomitant infiltration. At catchment scale, more significant amounts stormwater must be collected managed to prevent from flooding mitigate discharge environment. Sustainable Urban Drainage Systems (SUDS) were developed alleviate these problems....
