ABSTRACT Aquifer recharge presents advantages for integrated water management in the anthropic cycle, namely, advanced treatment of reclaimed and additional dilution pollutants due to mixing with natural groundwater. Nevertheless, this practice represents a health environmental hazard because presence pathogenic microorganisms chemical contaminants. To assess quality extracted from recharged aquifers, groundwater systems Torreele, Belgium, Sabadell, Spain, Nardò, Italy, were investigated...
This study investigates the fate and transport of pathogens introduced by artificial groundwater recharge at Nardò fractured aquifer in Salento area, Italy. Wastewater effluents from a municipal treatment plant with known pathogen concentrations were injected into sinkhole migration was monitored six sampling wells. The quantified mathematical model describing colloid set three‐dimensional, parallel fractures spatially variable aperture. number their average fracture aperture determined...
Abstract In a literature review of the recent advancements in mathematical hydrologic models applied fractured karstic formations, we highlight necessary improvements fluid dynamic equations that are commonly to flow discrete fracture network (DFN) via channel models. Fluid and pollutant transport modeling karst aquifers should consider simultaneous occurrence laminar, nonlaminar, turbulent fluxes fractures rather than laminar by cubic law has been widely scientific literature. Some...
Two pilot-scale fractured aquifer models (FAMs) consisting of horizontal limestone slabs were employed to investigate the removal biocolloids suspended in reclaimed wastewater. To better understand behavior real aquifers, these FAMs intentionally not "clean". The fracture apertures randomly spread with soil deposits, and both preflooded wastewater simulate field conditions Nardo Salento area, Italy, where fractures are clean due artificial groundwater recharge. One was injected secondary...
Aquifer over-exploitation may increase coastal seawater intrusion by reducing freshwater availability. Fractured subsurface formations commonly host important reservoirs along sea coasts. These water resources are particularly vulnerable to the contamination due infiltration occurring through rapid pathways via fractures. Modeling of density driven fluid flow in fractured aquifers is complex, as their hydrodynamics controlled interactions between preferential pathways, 3D interconnected...
This study investigated the modeling of variably saturated flow and Ni transport in fractured rocks at a site (Altamura, southern Italy) polluted 2001 by unauthorized sludge waste disposal. Time‐lapse electrical resistivity tomography (ERT) infiltrometer experimental results were used to constrain near‐surface boundary conditions an unsaturated model. A plastic ring was as because its setup is very versatile adaptable many different geological conditions, taking into consideration...
[1] We examine the use of numeric flow solutions Navier-Stokes (N-S) equations to improve modeling in fractured karst aquifers. The N-S were discretized with both meshed finite difference method (FDM) and meshless smoothed particle hydrodynamics method. results using FDM model successfully compared those taken from literature. solved numerically for two practical problems aquifers: (a) horizontal displacement saltwater/freshwater sharp interface fissures due groundwater overexploitation (b)...
A pathogenic Escherichia coli (E.coli) O157:H7 and O26:H11 dose-response model was set up for a quantitative microbial risk assessment (QMRA) of the waterborne diseases associated with managed aquifer recharge (MAR) practices in semiarid regions. The MAR facility at Forcatella (Southern Italy) selected QMRA application. target counts pathogens incidentally exposed to hosts by eating contaminated raw crops or while bathing beaches coastal area were determined applying Monte Carlo Markov Chain...
Although the fractured aquifer of Salento supplies over 80% drinking water requirements local population, its exposure to pollution has recently increased. In recent years, owing arid climate and droughts, spreading wastewater on soil for irrigation become much more frequent. Consequently, hazardous pathogenic microorganisms released with have been transported into subsoil contaminated groundwater. An elaboration epidemiological data shown that population highest endemic gastroenteritis in...
A new two-step method has been developed for predicting three-dimensional (3-D) pollutant plumes and breakthrough curves (BTC) in fractured aquifers. Predicting fluid motion fields concentrations groundwater is a challenging task, due to the difficulties building 3-D discrete fracture network (DFN) with same geometry of fractures interconnections as studied aquifer computational complexity problem being modeled. To improve representation DFN, geological characterization apertures was...
