“…coli by BF were reported by Dash et al () in Haridwar, on the Ganges River, India, with a 99.9% removal of total coliforms and fecal coliforms. Similar results for the reduction or elimination of 95% of the total coliforms were obtained in the BF system installed in the Nile River, Egypt, in New Aswan (Hamdan et al, ). In a study done by Shamsuddin et al (), total coliforms and E .…”

“…Other countries such as India (Dash et al, ), China (Wu, Hui, Wang, Li, & Zeng, ), Korea (Lee et al, ), and Egypt (Hamdan, Sensoy, & Mansour, ) already use BF for supply purposes. The United States began to employ this technique because of its low cost, in addition to promoting the removal of waterborne pathogenic microorganisms such as Cryptosporidium spp.…”

In bank filtration (BF) technology, a production well is pumped near surface water and induces water flow from the river through a porous medium to the well by percolation into the soil.Several physical, chemical, and biological processes occur, providing a natural water treatment along the river banks. An experimental area was installed on the Beberibe River with 2 production wells and 7 monitoring wells. The BF potential in removing pathogenic intestinal parasites and analysis of physical-chemical and bacteriological parameters was evaluated, according to Standard Methods. River-aquifer interaction was characterized by piezometric levels of production wells. Monitoring of the wells was correlated with the water depth of the river and precipitation. Parasite analysis was performed using Hoffman, Pons, and Janer's methods of spontaneous sedimentation, followed by centrifugation and preparation of slides stained with acetic Lugol. Protozoa oocysts were isolated by a modified Ziehl-Neelsen method, preceded by sedimentation and centrifugation. The pathogenic protozoa found in samples from Beberibe River were Cryptosporidium spp., Giardia spp., Entamoeba histolytica/dispar complex, and Isospora belli. Pathogenic helminths were also detected: Ascaris lumbricoides, Strongyloides stercoralis, and hookworm eggs and larvae, Hymenolepis nana. In water samples from the production wells, no waterborne pathogens were found. The BF pilot project was effective in reducing levels of turbidity and color. Total coliforms and Escherichia coli were absent in the production wells.Piezometric levels of production wells and monitoring wells correlated with water depth of Beberibe River show hydraulic connection between the production wells and river, thus featuring a river-aquifer interaction. The BF pilot system showed potential for reduction or elimination of pathogenic intestinal parasites.

“…The RBF system operates in a number of regions around the world including countries in Europe (Hoffmann and Gunkel, 2011), Asia (Mustafa et al, 2016), Africa, (Ghodeif et al, 2016;Hamdan et al, 2013;Shamrukh and Abdel-Wahab, 2008), and in the United States (Drewes and Khan, 2010). In Brazil, studies were started by Sens et al (2006) in the Peri Lake in Santa Catarina, using RBF as a pretreatment for the removal of cyanobacteria and cyanotoxins.…”

The hyporheic environment is composed of a rich meiofauna that depends on water flow, organic matter, and oxygen. The concentration of meiofauna varies spatially (horizontal and vertical) and temporally. Several processes occur at this interface (groundwater and surface water), including biogeochemical processes involving meiofauna. A study of the hyporheic meiofauna community in the sediments of the Beberibe River, in Brazil, was conducted. Meiofauna attained peak densities of 942.8 organisms/10 cm2, with organisms distributed over six taxa, with 98% of them represented by rotifers, nematodes, and annelids. Density was higher in the dry season with an average of 653.1 organisms/10 cm2, and in more superficial sediments with an average of 739.6 organisms/10 cm2. Greater densities were found in coarser sediment with a higher percentage of organic matter. A river bank filtration (RBF) pilot project has been installed, with good results in the attenuation of contaminants and pathogens.

“…This plausible mechanism was observed and reported in many BF and alluvial aquifer fields (Bourg et al, 1993(Bourg et al, , 1994Eckert et al, 2006;Jacobs et al, 1988;Kedziorek et al, 2008;Thomas et al, 1994;Vega et al, 2017). However, it is worth noting that other mechanisms (e.g., the simultaneous mobilisation of Fe and Mn) have also been observed in many BF fields (Grischek et al, 2017;Hamdan et al, 2013;Matsunaga et al, 1993).…”
