“…Thus, DOC mineralization or adsorption overcompensated DOC releases from accumulated POC in the SAT cores in accordance to other studies (e.g., [19,26]). Studies reveal that low amounts of primary substrate (e.g., POC and DOC) can improve the removal of moderately degradable OMPs [27]. Alidina et al [28] observed a higher removal due to a higher microbial diversity when using a humic acid as a refractory substrate source.…”

Bank filtration (BF) and soil aquifer treatment (SAT) are efficient natural technologies in potable water reuse systems. The removal of many organic micro-pollutants (OMPs) depends on redox-conditions in the subsoil, especially on the availability of molecular oxygen. Due to microbial transformation of particulate and dissolved organic constituents, oxygen can be consumed within short flow distances and induce anoxic and anaerobic conditions. The effect of accumulated particulate organic carbon (POC) on the fate of OMPs in BF and SAT systems is not fully understood. Long-term column experiments with natural sediment cores from the bank of Lake Tegel and from a SAT basin were conducted to investigate the impact of accumulated POC on dissolved organic carbon (DOC) release, on oxygen consumption, on mobilization of iron and manganese, and on the elimination of the organic indicator OMPs. The cores were fed with aerated tap water spiked with OMPs to exclude external POC inputs. Complete oxygen consumption within the first infiltration decimeter in lake sediments caused mobilization of iron, manganese, and DOC. Redox-sensitive OMPs like diclofenac, sulfamethoxazole, formylaminoantipyrine, and gabapentin were eliminated by more than 50% in all sediment cores, but slightly higher residual concentrations were measured in effluents from lake sediments, indicating a negative impact of a high oxygen consumption on OMP removal.

The column system was operated in flowthrough mode at a loading rate of 0.09 m/day and a hydraulic retention time of 25 days under saturated flow conditions (45). Low-DOC nanofiltration permeated material (average, 0.6 mg/liter) was introduced as the feed water for the duration of the work described herein.…”

“…Allochthonous organic matter from terrestrial and often anthropogenic sources, such as municipal, industrial, and agricultural wastewater, contributes significantly to the organic content in freshwater systems (36). While much of the DOC released during human activity, including many emerging contaminants of concern, can be readily mineralized during MAR, certain trace organic chemicals, such as anticonvulsant drugs (e.g., primidone, carbamazepine) or artificial sweeteners (e.g., sucralose), appear to be more recalcitrant to biotransformation (22,28,42,45).…”

ABSTRACTThis study explores microbial community structure in managed aquifer recharge (MAR) systems across both laboratory and field scales. Two field sites, the Taif River (Taif, Saudi Arabia) and South Platte River (Colorado), were selected as geographically distinct MAR systems. Samples derived from unsaturated riverbed, saturated-shallow-infiltration (depth, 1 to 2 cm), and intermediate-infiltration (depth, 10 to 50 cm) zones were collected. Complementary laboratory-scale sediment columns representing low (0.6 mg/liter) and moderate (5 mg/liter) dissolved organic carbon (DOC) concentrations were used to further query the influence of DOC and depth on microbial assemblages. Microbial density was positively correlated with the DOC concentration, while diversity was negatively correlated at both the laboratory and field scales. Microbial communities derived from analogous sampling zones in each river were not phylogenetically significantly different on phylum, class, genus, and species levels, as determined by 16S rRNA gene pyrosequencing, suggesting that geography and season exerted less sway than aqueous geochemical properties. When field-scale communities derived from the Taif and South Platte River sediments were grouped together, principal coordinate analysis revealed distinct clusters with regard to the three sample zones (unsaturated, shallow, and intermediate saturated) and, further, with respect to DOC concentration. An analogous trend as a function of depth and corresponding DOC loss was observed in column studies. Canonical correspondence analysis suggests that microbial classesBetaproteobacteriaandGammaproteobacteriaare positively correlated with DOC concentration. Our combined analyses at both the laboratory and field scales suggest that DOC may exert a strong influence on microbial community composition and diversity in MAR saturated zones.

“…RBF, which is an important part of managed aquifer recharge (MAR) systems (Rauch-Williams et al, 2010), has been used for water supplies in Europe along the Rhine, Elbe, Danube, and Seine Rivers for over a century (Schubert, 2002;Tufenkji et al, 2002) and it has provided the majority of the drinking water for large cities in Russia (Filimonova and Shtengelov, 2013), the USA Roy et al, 2012), China (Wu et al, 2007) and other countries (Hamdan et al, 2013;Lee et al, 2009;Polomčić et al, 2013;Shamsuddin et al, 2014) over the last few decades. The obvious advantage of RBF is the conjunctive use of infiltrated surface water and groundwater from the alluvial catchments of intake structures (Polomčić et al, 2013), which ensure long-term productivity and stability of the water supply (Sprenger et al, 2011).…”

Keywords:Groundwater and surface water interactions Riverbank filtration Riverbed clogging Hydraulic conductivity MODFLOW s u m m a r y A steady-state flow regime in riverbank well fields is often violated by fluctuations in river stages and variations in groundwater extraction. In this study, a criterion of quasi-steady flow during filtration processes at riverbank well fields was introduced. Under the assumption of steady-state flow, an analytical approach for determining the key hydraulic parameters (aquifer transmissivity and riverbed filtration resistance) between a stream and a hydraulically connected aquifer during riverbank filtration was presented. An optimal regular observation network (consisting of the locations of monitoring wells and the observation regime), which is based on the model-oriented approach using an example of a riverbank well field near the Kuybyshev Reservoir, Russia, was designed to minimise the uncertainty in the estimates of hydraulic parameters. The analyses showed that the initial recession in the surface water levels for the simplest constant groundwater withdrawal patterns can be used to determine the key hydraulic parameters; the error in these estimated parameters was less than 7% or 12%, depending on the designed monitoring network. When comparing the two typical monitoring networks, observation line A-A that passes midway through the water supply wells performed better than observation line B-B that passes through the water supply wells when estimating the hydraulic parameters. The results of this study can be used as a reference for designing and optimising a monitoring network that aims to determine the key hydraulic parameters at riverbank well fields.
