“…Due to the stress of global climate change and water shortage, urban stormwater is quickly becoming a potential water resource (Bloetscher et al 2010;Furlong et al 2017;Voisin et al 2018). Managed aquifer recharge (MAR) is the purposeful recharge of stormwater to aquifers for subsequent recovery or environmental benefit, such as reducing flood disaster and reducing the negative effects of groundwater overexploitation (Bell et al 2008;Leonard et al 2015;Beganskas and Fisher 2017).…”

Managed aquifer recharge is an effective strategy for urban stormwater management. Chemical ions are normally retained in stormwater and groundwater and may accelerate clogging during the recharge process. However, the effect of water chemistry on physical clogging has not previously been investigated. In this study, we investigated the hydrogeochemical mechanism of saturated porous media clogging in a series of column experiments. The column was packed with river sand and added suspensions of kaolinite particles. Calcium chloride and sodium chloride are used as representative ions to study chemical effects. We found that an increase in ionic strength resulted in retention of kaolinite solids in the column, with a breakthrough peak of C/C0 value of 1 to 0.2. The corresponding hydraulic conductivity decreased with increased solids clogging. Divalent cations were also found to have a greater influence on kaolinite particle clogging than monovalent cations. The enhanced hydrochemical‐related clogging was caused by kaolinite solids flocculating and increasing the deposition rate coefficient by 1 to 2 times in high ionic strength conditions. Three clogging mechanisms of kaolinite solids are proposed: surface filtration, inner blocking, and attachment. This study further deepens the understanding of the mechanisms of solids clogging during aquifer recharge and demonstrates the significance of ionic strength on recharge clogging risk assessments.

“…Studies have reported the substantial roles of streets in conveying runoff and discharge of environmental, faecal and antibiotic-resistant bacteria to various surrounding water systems, such as streams (Baral et al, 2018), lakes (Zhang et al, 2016), waterways (Calderon et al, 2017) or groundwater (Voisin et al, 2018). Analyses of soils from a motorway or highly trafficked road in Copenhagen have revealed the presence of microbial polycyclic aromatic hydrocarbon degraders (Johnsen et al, 2006;Johnsen et al, 2014).…”

Summary Streets are constantly crossed by billions of vehicles and pedestrians. Their gutters, which convey stormwater and contribute to waste management, and are important for human health and well‐being, probably play a number of ecological roles. Street surfaces may also represent an important part of city surface areas. To better characterize the ecology of this yet poorly explored compartment, we used filtration and DNA metabarcoding to address microbial community composition and assembly across the city of Paris, France. Diverse bacterial and eukaryotic taxonomic groups were identified, including members involved in key biogeochemical processes, along with a number of parasites and putative pathogens of human, animals and plants. We showed that the beta diversity patterns between bacterial and eukaryotic communities were correlated, suggesting interdomain associations. Beta diversity analyses revealed the significance of biotic factors (cohesion metrics) in shaping gutter microbial community assembly and, to a lesser extent, the contribution of abiotic factors (pH and conductivity). Co‐occurrences analysis confirmed contrasting non‐random patterns both within and between domains of life, specifically when comparing diatoms and fungi. Our results highlight microbial coexistence patterns in streets and reinforce the need to further explore biodiversity in urban ground transportation infrastructures.

“…High concentrations of FIB (up to 5 × 10 5 most probable number [MPN] g −1 of dry weight) were reported in the literature for several water bodies, including beach sand and sediments from estuaries and other coastal areas (Craig, Cromar, & Fallowfield, 2002, Halliday & Gast, 2011); lakes (Ishii, Ksoll, Hicks, & Sadowsky, 2006), rivers (Craig et al, 2002; Donovan et al, 2008; Kovacic, Tripkovic, Galov, & Žitko, 2011), and infiltration aquifer recharge systems (Voisin, Cournoyer, Vienney, & Mermillod‐Blondin, 2018). Analyses of the relations between the finest fractions of sediments and the occurrence of bacteria suggested a strong impact of organic matter on their metabolic states (e.g., Characklis et al, 2005; Fischer et al, 2002; Voisin et al, 2018). Some allochthonous EC populations were also found to be remobilized from riverbed sediments during erosive flood events (Brookes et al, 2004; Frey et al, 2015; Ribolzi, Evrard, et al, 2016; Ribolzi, Rochelle‐Newall, et al, 2016).…”

Responses of streambed bacterial groups to cycles of low‐flow and erosive floods in a small peri‐urban stream

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 the hydrological regime and the loads and persistence of CSO-borne bacterial contaminants among benthic sediments of a small peri-urban stream were explored. Combined sewer overflow events and their impact on benthic sediment layers at a short distance from a CSO were monitored. Concentrations of Escherichia coli (EC) and intestinal enterococci (IE) and of two bacterial pathogens, Pseudomonas aeruginosa (PA) and Aeromonas caviae (AC), were assessed.Relations with hydraulic, hydromorphic and physicochemical factors were analysed.PA cells in benthic sediments increased exponentially with time (0.15 log PA per day), as long as the river discharge remained below the sediment transport. Cycles of erosive floods and low-flow periods were found to play a critical role in PA settling and growth among benthic riverbed sediments. These hydrological and hydraulic shear forces did not correlate with changing IE, EC, and AC concentrations in the benthic sediments. Their dynamics were rather related to changing physicochemical conditions (total N, phosphate, and organic carbon). AC population size decreases most rapidly with a mean rate of 0.04 log per day according to the duration of the low-flow period, indicating a poor tropism of AC for river systems. River sediments were found significant biotopes for PA outdoor development. These analyses demonstrate the significance of PA and AC as long-and short-term indicators, respectively, of a river microbiological quality.
