Nevertheless, almost 20% of the points sampled present low to moderate degrees of faecal contamination. These cases are closely related with leaks and the discharge of urban wastewater. A further contributory factor is the existence of high-risk irrigation practices, such as inundation with untreated (or ineffectively treated) urban wastewater where the piezometric levels are less than 20 m below ground level. Consequently, the incidence of contamination detected corresponds to specific situations or practices, in particular geographic areas and is generally of very limited durationspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Vega de Granada aquiferFaecal contaminationUrban wastewaterjournal articleopen access
