“…MAR can be applied as a measure to reverse and prevent coastal aquifer salinization related to the overexploitation of groundwater and water table decline [47]. The quality of the produced water, available for drinking or irrigation processes, is strongly dependent on the aquifer’s hydrogeochemical characteristics and on the MAR system design and operation [48]. MAR is the purposeful recharge of water to aquifers for subsequent recovery or environmental benefit.…”

Increasing salt intake has substantial negative impacts on human health and well-being. This article focused on the construction of Driver-Pressure-State-Impact-Response (DPSIR) framework for drinking water sodium (DWS) followed by a review on the published studies regarding salinity intrusion, DWS, and their effects on health perspectives in Bangladesh. Saline water is an important factor for hypertension or high blood pressure in the coastal areas. DWS can also lead women, especially pregnant women, to an increased risk of (pre)eclampsia, hypertension, as well as infant mortality. Several interventions, such as rainwater harvesting, pond sand filter (PSF) system, managed aquifer recharge (MAR), and pilot scale solar-powered desalination plants, such as reverse osmosis (RO), were reviewed on the context of their effectiveness in controlling drinking water sodium. Although rainwater consumption has the positive impact of low or no sodium intake, it still possesses negative impacts from not having vital minerals. A steady increment in sodium concentration through the span of the dry season was observed in MAR. It is, subsequently, important to increase awareness on DWS intake by providing and adopting correct technological interventions and training communities on the maintenance of the adaptive measures.

“…The geochemistry and the reducing and/or oxidising conditions affected the dominant As species, with the higher redox potential Eh to favour the presence of As(III) [55]. The mean concentration of As in groundwater from eight wells which are situated close to Paphos (Cyprus) was found to be 1.3 µg L −1 in samples that were collected during three sampling periods (November 2006 to October 2011) [63].…”

This study presents an overview about the arsenic (As) contamination and its sources in two European countries. Arsenic is a highly toxic element in its inorganic form and it is carcinogenic to human seven in low concentrations. The occurrence of As in surface water, stream and marine waters, groundwater, bottled water, sediment, soil, mines, and seafood, its environmental origin, and its impacts on human health are discussed. The classes of Geoaccumulation Index for As in Greece ranges from practically uncontaminated to extremely contaminated, and in Cyprus varies between practically uncontaminated and heavily contaminated. In many cases, the As contamination reaches very high concentrations and the impacts may be crucial for the human health and ecosystems. Physicochemical properties, regional climate and geological setting are controlling the occurrence and transport of As. In Greece and Cyprus, the geology, lithology, and ore-deposits are the most important factors for the variation of As contents in water, soil, and sediment. The dominant As species are also determined by the location and the redox conditions. The findings of this paper may be useful for scientists and stakeholders monitoring the studied areas and applying measures for protection of the human and terrestrial ecological receptors (plants, avian, mammals).

“…The non-reactive transport models for solute are based on the Advection Dispersion Equation (ADE) (Eusuff and Lansey, 2004, Tutulic et al, 2011, Rahman et al, 2013, Winiarski et al, 2013. This model could be extended to include geochemical and biogeochemical reactions (e.g., Tzoraki et al, 2018). Over the last decade, few studies evaluated the potential of such models to simulate artificial groundwater recharge and associated transport of contaminants.…”

“…The domain of the adopted model was determined from the topography of the field but recharge estimation was based on simplified water-balance model and did not take into account the variations of the water inflow over the time. A similar model to Tutulic et al (2011) was employed by Tzoraki et al (2018) for the assessment of the operation efficiency of a MAR system in Cyprus. In this study, the model was coupled with the geochemical model PHREEQC in order to take into account the chemical composition of water mixing with reactive contaminants (i.e., phosphate and copper).…”

In this paper, a 3D model of the vadose zone/aquifer system is implemented to simulate the fate of water and pollutants in storm water infiltration basin located in Chassieu (Lyon area, France). The geometry of the Django Reinhard experimental site was built from the DEM data of the National Geographic Institute (resolution of the digital elevation model is 1 m). The well-known Richards model is used to simulate the flow in the saturated and unsaturated zone of the study site. The transfer of solutes in the basin/aquifer system is modelled by the advection-dispersionequation (ADE). The infiltration rate was calculated using a basin mass balance based on surface data (measured flowrate, water level in the basin and topography). In the first step, the calibration of the 3D groundwater flow model is carried out by comparison between observed and simulated piezometric levels. This calibration is based on a reference rainy episode chosen from the data measured by the OTHU. The results have shown a reasonable restitution of the measured data in view of the complexity of the real system. The calibrated set of parameters appeared suitable to simulate a period of 1 month presenting two significant rain events. The advection-dispersionequation was then calibrated in order to reproduce the electrical conductivity decrease (intensity and dynamics) observed in control piezometers. The calibrated transport model was used to simulate the fate of a solute pollutant considered as a tracer. A characterization of the concentrations in control piezometers was carried out by posttreatment of the 3D calculation. Three main results were obtained: (1) 0 to 24% of the injection concentration could be recovered depending on the location of the piezometer around the basin with respect to the aquifer main flow direction, (2) the averaged concentration decreased by 40% if the measuring device is lowered by 5 m (effect of the depth) and (3) capillary trapping promotes a retention of up to 20% of the injected tracer in the vadose zone.
