“…The role of the HZ in the movement and attenuation of natural dissolved organic carbon between groundwater and surface water has been long recognised (Boulton et al, 1998), as has the potential of river bank filtration for the removal of organic pollutants (Tufenkji et al, 2002). A number of studies have shown the persistence of microorganics from surface water into groundwater, albeit at lower concentrations (Banzhaf et al, In press;Heberer et al, 2008;Lewandowski et al, 2011).…”

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.

“…There, alluvial soil consists of 90% sand. Nevertheless, together RBF sites in Jordan, US, and Netherlands show E. coli removal rates of up to 99% (Saadoun et al, 2010;Weiss et al, 2002;Tufenkji et al, 2002). These studies indicate that most RBF sites have been built on sandy aquifers.…”

Abstract:Shallow riverbank groundwater along permanent rivers represents a good water resource. The particle distribution in a soil determines its hydraulic conductivity, which is a critical criterion in the selection of riverbank sites for filtration. Over time, particle size distributions (PSD) may change because of clogging and the weathering of local soil. In this study, the effect of PSD on the removal of color and Escherichia coli (E. coli) from groundwater was investigated. A laboratory scale model was constructed to determine the horizontal hydraulic conductivity of local alluvial soil with different PSD. The results were analyzed on the basis of two factors: (a) different alluvium soils and (b) soil uniformity coefficient (C u ). The alluvial soils (Sands A, B, C, and D) showed hydraulic conductivities ranging from 6.87 × 10 -4 m/s to 8.96 × 10 -4 m/s. Results indicated that an increase in C u can improve the removal of color and E. coli. The Sand A, which had a well-graded PSD and the highest C u value, achieved color and E. coli removal rates of up to 70% and 100%, respectively.
