“…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. It involves methods such as riverbank filtration, stream bed weirs, infiltration ponds, and injection wells in order to increase groundwater storage [47]. Integrated holistic approaches such as the rainwater harvesting systems and PSF near rainwater-supplied surface ponds, and rainwater-supplied MAR, are being upgraded from a single rainwater or PSF system.…”

Impacts of Salinity Intrusion in Community Health: A Review of Experiences on Drinking Water Sodium from Coastal Areas of Bangladesh

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.

“…It is a dynamic tool that helps the analysts to estimate the significance of subjectivity components and provides essential information about the influence of weights for each parameter. The sensitivity analysis has been used in coastal aquifer vulnerability validation and in flood hazard area assessment by Kazakis et al [27,52], in the delineation of zones for the application of Managed Aquifer Recharge (MAR) [53], as well as in groundwater risk index by Lezzaik et al [54]. Clearly, the single sensitivity constitutes a robust method for model validation in environmental issues.…”

The aim of this study was the assessment of groundwater vulnerability and pollution risk of the Perivleptos karst aquifer in the northwestern part of Greece. Hence, the EPIK method has been applied within the study area. Additionally, a detailed literature overview has been obtained, including the worldwide application of the EPIK method. The hazard map has been developed for the implementation of risk assessment. The resulting vulnerability map was divided into four classes and showed especially high to very high vulnerability. The subsequent hazard assessment has shown mostly low to moderate endangerment for the northern part of the study area, which is mainly covered by forest, while the areas covered by urban and industrial, as well as agricultural land, use primarily show high to very high endangerment. Concluding in the risk map, the study area consists of 13% of very high, 48% of high, 36% of moderate and 4% of low risk of contamination. According to the literature overview, the EPIK method was mostly used in combination with other vulnerability assessment methods, and results have been validated through tracer tests, sensitivity analysis or comparing to other methods. In this study, an additional single parameter sensitivity analysis was obtained for validation of the EPIK parameters.

“…The analytical hierarchy process (AHP), introduced by Saaty [38], has proven to be useful for spatial decision problems with a large number of criteria [39]. It can be used to combine all the representative criteria into a "criteria tree", with different levels of priorities accordingly [9,13,40,41]. Therefore, AHP was introduced to assist the choice criteria and weight determination to improve the accuracy of GIS based analysis.…”

Towns along the West Coast of South Africa are facing water shortages due to climate change and increasing water demand. Managed aquifer recharge (MAR) is considered as a solution to improve water security. This paper presents a two-step method of combining geographic information system (GIS) based analysis with numerical modeling to select suitable sites for implementing MAR in the West Coast area. Many factors were taken into account to generate the initial map for suitable sites through GIS based analysis. Subsequently, groundwater flow modeling was adopted to verify and optimize the suitable sites selected by GIS based analysis. The result showed that the map for suitable sites produced by the GIS based analysis was reasonable from a spatial aspect, but due to the lack of groundwater seepage information, the most suitable sites developed are not necessarily the optimal choices in practice. With the aid of both the spatial analysis in GIS and seepage simulation, this two-step analysis approach provides a reliable solution to identify suitable sites for implementing MAR. This approach provides a much better reference to the study of suitable sites and possible impacts of implementing MAR in an aquifer in similar areas with water stress.
