“…For the passive solute (bromide), the estimated mean early arrival time, s ea , to the water table predicted by the MIM and the ADE transport models are s ea 5 2 and 5 years, respectively. Note that for carbamazepine, the relatively short mean early arrival time, s ea , to the water table, predicted by the 3-D MIM transport model (8 year) is in agreement with detectable concentrations of sulfamethoxazole found in the groundwater at the Glil Yam site [Avisar et al, 2009].…”

Field-scale transport of conservative and reactive solutes through a deep vadose zone was analyzed by means of two different model processes for the local description of the transport. The first is the advection-dispersion equation (ADE) model, and the second is the mobile-immobile (MIM) model. The analyses were performed by means of three-dimensional (3-D), numerical simulations of flow and transport considering realistic features of the flow system, pertinent to a turf field irrigated with treated sewage effluents (TSE). Simulated water content and concentration profiles were compared with available measurements of their counterparts. Results of the analyses suggest that the behavior of both solutes in the deep vadose zone of the Glil Yam site is better quantified by the MIM model than by the ADE model. Reconstruction of the shape of the measured solute concentration profiles using the MIM model required relatively small mass transfer coefficient, c, and relatively large volume fraction of the immobile water h im . This implies that for an initially nonzero solute concentration profile, as compared with the MIM model, the ADE model may significantly overestimate the rate at which solutes are loaded in the groundwater. On the contrary, for an initially zero solute concentration profile, as compared with the MIM model, the ADE model may significantly underestimate solute velocities and early arrival times to the water table. These findings stem from the combination of relatively small c and relatively large h im taken into account in the MIM model. In the first case, this combination forces a considerable portion of the solute mass to reside in the immobile region of the water-filled pore space, while the opposite is true in the second case.

“…Additionally, researchers worldwide have highlighted the risks posed by high-mobility compounds, given the possible leaching that may pollute groundwater sources [131,132,134,135]. For example, in some amoxicillin-degradation products, it was observed that high-mobility compounds polluted the groundwater of wastewater-irrigated agricultural fields [133].…”

For centuries, wastewater has been improperly used in agriculture, presenting potential risks to public health and the environment. In the context of scientific development, and confronted by an increasing water crisis, wastewater reuse merits consideration because the practice helps decrease water use pressure and moderates water pollution. Thus, this article presents a literature review that addresses the effects, both positive and negative, of wastewater use in agriculture, emphasizing the effects on the soil environment. The literature review reveals that, until the 1990s, research studies promoted the use of wastewater for irrigation purposes from a treatment approach, while proposing "end of pipe" conventional solutions. However, more recent research studies (2012)(2013)(2014)(2015)(2016) reveal that agricultural reuse significantly affects soil texture properties, while also causing possible alterations of the biomass and microbiota. In addition, research in this period has been oriented to the quantitative evaluation of microbiological risk.

“…Antibiotic compounds consistently detected in WWTP effluents include azithromycin, clarithromycin, ciprofloxacin, erythromycin, norfloxacin, ofloxacin, sulfamethoxazole, and trimethoprim (Fatta-Kassinos et al 2011b;Li and Zhang 2011;Sim et al 2011;Ghosh et al 2009;Watkinson et al 2007). Additionally, some studies have detected antibiotics, such as erythromycin and tetracycline, in wastewaterirrigated soils (Chen et al 2011;Kinney et al 2006) and sulfamethoxazole and erythromycin have even been discovered in groundwater under land irrigated with wastewater effluents (Avisar et al 2009;Siemens et al 2008).…”

The reuse of treated wastewater (TWW) for irrigation is a practical solution for overcoming water scarcity, especially in arid and semiarid regions of the world. However, there are several potential environmental and health-related risks associated with this practice. One such risk stems from the fact that TWW irrigation may increase antibiotic resistance (AR) levels in soil bacteria, potentially contributing to the global propagation of clinical AR. Wastewater treatment plant (WWTP) effluents have been recognized as significant environmental AR reservoirs due to selective pressure generated by antibiotics and other compounds that are frequently detected in effluents. This review summarizes a myriad of recent studies that have assessed the impact of anthropogenic practices on AR in environmental bacterial communities, with specific emphasis on elucidating the potential effects of TWW irrigation on AR in the soil microbiome. Based on the current state of the art, we conclude that contradictory to freshwater environments where WWTP effluent influx tends to expand antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes levels, TWW irrigation does not seem to impact AR levels in the soil microbiome. Although this conclusion is a cause for cautious optimism regarding the future implementation of TWW irrigation, we conclude that further studies aimed at assessing the scope of horizontal gene transfer between effluent-associated ARB and soil bacteria need to be further conducted before ruling out the possible contribution of TWW irrigation to antibiotic-resistant reservoirs in irrigated soils.
