Thermal energy is utilized as an environmentally friendly energy source for seasonal heat and cold storage on a global scale. Specifically, the aquifer thermal energy storage system is highlighted for being cost-effective in cooling and heating applications. The study assesses the sustainability of the aquifer thermal energy storage in the Halabja-Khurmal sub-basin by evaluating six critical criteria: groundwater transmissivity, groundwater temperature, groundwater discharge, groundwater chemistry, population density, and per capita GDP. A multi-criteria decision analysis judgment is applied to analyze all criteria, resulting in a consistency ratio of 0.3% in the analytical hierarchy process. Consequently, the sustainability map for Aquifer Thermal Energy Storage in the Halabja-Khurmal sub-basin for heating reveals that 26.45% of the area is strongly sustainable located in the north and southwestern part of the sub-basin, 73.53% is moderate in the east, central, southeast, and southern regions, 0.02% is weakly sustainable as a tiny area in the southwestern. On the other hand, the sustainability map for Aquifer Thermal Energy Storage in the Halabja-Khurmal sub-basin for cooling reveals that 19% of the area is strongly sustainable located in the north, and southwestern parts of the sub-basin, 78% is moderate in the northeast, east, southeast, west, central, and southern regions, 3% is weakly sustainable as spots in the west and southwestern areas.

Aquifer Storage and Recovery (ASR) has been promoted as a technological solution to mitigate groundwater stress worldwide. Despite its potential, the adoption of ASR remains limited, primarily due to social and economic barriers. This study examines the socioeconomic and socio-environmental impacts of a pilot ASR initiative in selected villages of South Bihar, India. By analysing the socioeconomic and environmental outcomes through an interdisciplinary approach, we highlight the short-term, medium-term and long-term challenges of implementing "participatory" technology-driven interventions in resource-constrained rural communities. Our findings underscore the significance of local socioeconomic conditions, participatory governance, and long-term sustainability in the diffusion of ASR technologies.

Managed aquifer recharge (MAR) is known to increase available water quantity and to improve water quality. However, its implementation is hindered by the concern of polluting aquifers, which might lead to onerous treatment and regulatory requirements for the source water. These requirements might make MAR unsustainable both economically and energetically. To address these concerns, we tested reactive barriers laid at the bottom of infiltration basins to enhance water quality improvement during soil passage. The goal of the barriers was to (1) provide a range of sorption sites to favor the retention of chemical contaminants and pathogens; (2) favor the development of a sequence of redox states to promote the degradation of the most recalcitrant chemical contaminants; and (3) promote the growth of plants both to reduce clogging, and to supply organic carbon and sorption sites. We summarized our experience to show that the barriers did enhance the removal of organic pollutants of conce...

This proposal outlines a pilot initiative to evaluate the performance and long-term viability of a novel artificial aquifer concept for sustainable groundwater recharge and storage. The concept has been developed and filed for patent consideration with the Sri Lanka Inventors Commission. We now seek collaboration with the National Water Supply and Drainage Board (NWSDB) to validate the design through practical field testing.
4.1.2 Project Background and Justification
Sri Lanka is increasingly vulnerable to water scarcity due to seasonal rainfall variability, over-extraction of groundwater, and shifting climatic patterns. The proposed subsurface artificial aquifer system offers a viable climate-adaptive infrastructure solution to enhance water availability during the dry season.
The concept uses a series of 450 mm diameter and 2.5 m long Hume pipes, installed at a depth of 6 meters across a 1-hectare land area. These pipes are linked to a groundwater collection trench (100 m length, 1 m width, 6 m depth) designed to intercept seepage and store up to 3.48 million liters of water annually.

The Upper Wadi Fara' basin, located at the West Bank, Palestine, has an average annual rainfall of 500 mm, which occurs only during winter. Agriculture uses stored soil water and complimentary irrigation from groundwater. Water harvesting (WH) and managed aquifer recharge (MAR) therefore is essential for sustainable water resources management in the basin. This study focuses on the comparison between two methods to determine best practices for WH/MAR. The first method uses the change in water productivity and can be considered a one parameter cost benefit analysis (CBA). The other method concerns the multi year water allocation system (MYWAS), which uses water demand curves to evaluate economic scenarios. It is concluded that the highest cost effectiveness of WH/MAR measures in upper Wadi Fara' basin is reached when water is stored as soil water. However, this is a politically disputed measure in the Israel -Palestine shared aquifer. Both models are useful tools in decisive stakeholder participation processes.

Anantapur district in Andhra Pradesh is one of the most drought-prone regions in India, with annual average rainfall below 500 mm. Overexploitation of groundwater, low soil moisture retention, and irregular monsoons have rendered vast tracts of agricultural land unproductive. Traditional water conservation measures are insufficient to meet the region’s growing water stress.
The proposed solution involves constructing engineered sub-surface aquifer systems using nano-fabric material across identified degraded lands. These structures will be combined with surface reservoirs to maximize rainwater capture and recharge groundwater sustainably.

The Atlantis Water Supply Scheme (AWSS, Western Cape, South Africa) has been in operation for about 40 years as a means to supply and augment drinking water to the town of Atlantis via managed aquifer recharge (MAR). In this study, the numerical model MODFLOW for groundwater flow and contaminant transport was used in support of the management of the AWSS. The aims were: (i) to calibrate the MODFLOW model for the MAR site at Atlantis; (ii) to run realistic scenarios that cannot be replicated through experiments; and (iii) to make recommendations in support of efficient and sustainable management of the aquifer. MODFLOW was calibrated through comparison of observed and simulated groundwater levels (R 2 between 0.663 and 0.995). Scenario simulations indicated possible drawdowns between < 5 m (low groundwater abstraction and low artificial recharge of groundwater through infiltration basins) and > 20 m (high abstraction and high artificial recharge) at localized areas of the Witzand wellfield. At Silwerstroom, large drawdown levels were not predicted to occur, so this wellfield could be exploited more without affecting the sustainability of the groundwater resource. Groundwater moves from the infiltration basins towards the Witzand wellfield at a rate of 120-150 m•a -1 . The modelling results supported recommendations for balancing groundwater abstraction and artificial recharge volumes, monitoring the water balance components of the system, the potential risks of groundwater contamination and the delineation of groundwater protection zones.

The primary aquifer at Atlantis (Western Cape, South Africa) is ideally suited for water supply and the indirect recycling of urban stormwater runoff and treated domestic wastewater for potable purposes. The relatively thin, sloping aquifer requires careful management of the artificial recharge and abstraction for balancing water levels. Water quality management is a further key issue at Atlantis for ensuring the highest quality potable water. Groundwater quality varies from point to point in the aquifer, while urban runoff and wastewater qualities vary greatly. The layout of the town allows for the separation of stormwater from the residential and industrial areas as well as separate treatment of domestic and industrial wastewater. This permits safe artificial recharge of the various water quality portions at different points in the aquifer, either for recycling or for preventing seawater intrusion. All of the management actions are dependent on detailed data collection and this paper describes the various parts of the system, describes the data collection activities, and provides results of the monitoring and aquifer responses over the past four decades. Challenges related to iron fouling of production boreholes are also described. The presence of emerging contaminants was studied in 2008 but requires follow-up research for establishing the extent of any possible threat to water recycling. In order to address the shortcomings of the system a risk management plan based on the Hazard Analysis and Critical Control Points approach was developed. Lessons learnt from the Atlantis experience can be transferred to other potential sites for establishment of similar systems in arid and semi-arid areas of South Africa and the African continent.

This paper aims to investigate the potential existence of wadi-aquifer interaction in the 320 km 2 semiarid Faria catchment using a tracer-based methodology. Faria catchment is located in the northeastern part of the West Bank and accounts for 6 % of the total West Bank's area. Surface runoff in the catchment consists mainly from springs discharge, runoff generated from winter storms, untreated wastewater effluent from the eastern part of Nablus City and Al-Faria refugee camp, and the return flow from the adjacent agricultural areas. As such, wadi-aquifer interaction may pose serious pressures on groundwater quality which is the only water source for the agricultural and domestic uses in the area. In this study, and in order to investigate the potential existence of wadi-aquifer interaction in the Faria catchment, a tracer-based experiment was conducted. The experiment was carried out using Uranine as a conservative tracer material. A representative reach of 600 m was chosen and was divided into four equal distances. A concentration curve was plotted at each section (monitoring point) with the help of OTIS (solute transport model for streams and rivers) which was used to calibrate the measured concentration curves. Accordingly, the flow rates were estimated at the different monitoring points. The obtained results proved that transmission losses took place in the wadi bed sediments of the selected reach and with different ratios. The percent loss in the flow rates' values in the different sections ranged from 4.8 to 68.3 %. It was found that the largest transmission losses took place in the section between the first and the second monitoring points. In conclusion, tracer-based methodology is considered as a modern and innovative technique that was used via this research to understand the nature of the wadiaquifer interaction in Faria catchment and to quantify it as well.

Nos últimos anos a União Europeia produziu diversa legislação relativa aos recursos hídricos subterrâneos, tendo por base a sua preservação, conservação e gestão eficiente. Portugal transpôs e implementou estas orientações, incorporando assim a questão da proteção das águas subterrâneas no planeamento, nomeadamente à escala municipal. Este trabalho pretende evidenciar a utilidade dos inventários de emergências, bem como a sua relação com a análise de vulnerabilidade preconizada na Lei Portuguesa, constituindo assim, metodologias importantes de suporte à gestão destes importantes recursos, tanto a nível municipal como local. Deste modo, apresentam-se os resultados de um inventário de recursos hídricos subterrâneos realizado na pequena bacia hidrográfica da Ribeira de Sá, localizada no concelho de Castelo de Paiva, em Portugal. Os resultados obtidos nesta área reforçam claramente a importância do conhecimento inicial dos recursos existentes, nomeadamente através da inventariação, para que se definam medidas proteção e gestão adequada.

Arid regions face a dual threat of declining groundwater quantity and quality. This study examines these interconnected challenges in the diverse aquifers of Iran's Jazmurian Basin using GIS and statistics. The study reveals significant spatial variations in salinity, hardness, and sodium content. Of particular concern is the rising electrical conductivity (EC) across most aquifers, especially in the east, which indicates potential water quality degradation. The relationship between groundwater level and salinity is intricate and requires site-specific management. Cluster analysis has identified three distinct groundwater profiles: deep formations that require geological understanding for salinity control, highquality zones that need recharge protection, and areas that struggle with salinity sources that require identification. Factor analysis identifies salinity and aridity, mineral content related to rock weathering and agriculture, recharge zones requiring protection, and complex interactions between specific ions and groundwater level as key drivers. This study highlights the importance of implementing comprehensive management strategies considering spatial variations, temporal trends, and unique drivers. Targeted interventions, sustainable water use, and effective monitoring programs are essential for safeguarding this vital resource in drought-prone regions. Further research is necessary to refine our understanding of human influences and unique geochemical processes shaping each aquifer system, ultimately enhancing global arid zone groundwater management.

Depletion of groundwater resources is currently one of the main environmental problems worldwide. The major groundwater systems on earth face large overexploitations with serious associated quality and quantity problems. Impacts of groundwater depletion involve serious economic damages from declining water tables, damages to linked groundwaterecosystems, and consequences of water quality deterioration. However, during recent years another problem related with groundwater depletion has been gaining importance and attention— land subsidence that occurs in areas with specific geological characteristics in association with groundwater exploitation. Despite the large socio-economic impacts of land subsidence most of its effects are still not well analyzed and not properly recognized and quantified. We collected information on land subsidence from 119 sites around the world and, in the absence of quantified estimates, developed a land subsidence extent index. Then, we demonstrated qualita...

MAR remains relatively underutilized in Central Asia despite its potential to address water scarcity issues, particularly those related to seasonal fluctuations in water availability. Thus, the objective of this study was to produce a map depicting the potential suitability of managed aquifer recharge (MAR) implementation in Kazakhstan. Employing a multi-criteria decision analysis framework, five distinct physical criteria were integrated and visualized within a Geographic Information System (GIS) to delineate the intrinsic potential for MAR. To demonstrate the practical utility of the generated map, it was applied to the Zhambyl region in Southern Kazakhstan, an area previously afflicted by water scarcity challenges. The intrinsic MAR potential map was overlaid with remote sensing data identifying potential water sources and water utilization patterns. This overlay facilitated the identification of priority areas with potential for further evaluation for MAR implementation. The map developed for Kazakhstan represents the first spatial representation of MAR potential within the region, serving to raise awareness regarding the feasibility of MAR application. It is anticipated that dissemination of this map will enhance understanding among water management professionals, potentially catalysing the integration of MAR methodologies into regional water management strategies.

Mountain-front recharge (MFR), defined as all inflow to a basin-fill aquifer with its source in the mountain block , is an important water budget component globally, particularly in arid and semiarid regions . Shifts in water supply in mountainous systems induced by climate change are likely to alter the timing and magnitude of MFR , and demand-side stresses on basin-fill aquifers will likely increase as surface water supplies become less reliable . As these stresses intensify, we are challenged to predict future MFR. To do this effectively, we must better quantify the processes controlling MFR and the components of MFR with improved characterization of flow and transport time scales. Mountain-front recharge components can be divided into three types: (1) surface MFR, or recharge that occurs as infiltration from ephemeral and perennial streams along the mountain front; (2) diffuse mountain-block recharge (MBR), or spatially distributed subsurface inflow from the mountain block to the adjacent basin fill; and (3) focused MBR, or subsurface inflow that occurs along discrete, permeable geologic features such as a fault or beneath streams in the unconsolidated sediment . Distinguishing between these components is necessary as they operate on different spatial and temporal scales, and thus could respond to climate change in profoundly different ways. However, characterizing MFR components is challenging because, first, they often exhibit similar chemical and stable

Despite the widespread presence of groundwater recharge check dams, there are few studies that quantify their functionality. The objectives of this study are (i) to assess groundwater recharge in an ephemeral river with and without a check dam and (ii) to assess sediment build-up in the check-dam reservoir. Field campaigns were carried out to measure water flow, water depth, and check-dam topography to establish water volume, evaporation, outflow, and recharge relations, as well as sediment build-up. To quantify the groundwater recharge, a water-balance approach was applied at two locations: at the check dam reservoir area and at an 11 km long natural stretch of the river upstream. Prediction intervals were computed to assess the uncertainties of the results. During the four years of operation, the check dam (storage capacity of 25,000 m 3 ) recharged the aquifer with an average of 3.1 million m 3 of the 10.4 million m 3 year -1 of streamflow (30%). The lower and upper uncertainty limits of the check dam recharge were 0.1 and 9.6 million m 3 year -1 , respectively. Recharge from the upstream stretch was 1.5 million m 3 year -1 . These results indicate that check dams are valuable structures for increasing groundwater resources in semi-arid regions.

Groundwater governance comprises the enabling framework and guiding
principles for management of groundwater in line with society’s goals.” There is a good understanding of the need for effective
governance of groundwater and conjunctive use as evidenced by too
many examples of overexploitation and pollution of groundwater. MAR is seen as one potential solution and its well-planned use has resulted in very positive outcomes. However, its inappropriate use can also cause problems. While some countries have documents to guide the use of MAR, and thereby facilitate exemplary MAR projects and
programs, until now there has been no international overview of the wide range of governance arrangements for MAR. These are needed to address both water resources policies and groundwater quality protection.
The book is organized in three main sections, each written by a team of authors:
• Section 1 gives an overview of purposes, types, source waters, advantages and challenges, essential requirements, and stakeholder involvement. MAR is at the interface of surface water and groundwater management and draws on good scientific and communication skills to make progress.
• Section 2 focuses on less-studied elements, namely innovative policies and regulations, which need to be soundly based to underpin the viability of MAR. This is intended to be of prime interest to water resources planners or managers, and lays out a framework that can be used in both developing and advanced jurisdictions and will allow, and even encourage, MAR to be implemented.
• Section 3 takes a parallel track focused on water quality management for health and environmental protection from a variety of starting positions and capabilities. This is fundamental to managing risk and to sustainable MAR operations, including the management of clogging and recovery efficiency.

Although it is evident that pore water pressure drawdown impacts all soil properties, the current piezometric condition is often estimated with few and poorly located points, joined with theoretically invalid curves, and inadequately extrapolated into the future. Therefore, the aspects necessary for estimating the underdrained pore water pressure profile are established here. Measurement techniques are reviewed, and a simple model is presented for fitting the results of a piezocone dissipation test to predict field pressure without waiting for total dissipation. Guidelines are also established for designating the most convenient measurement points, as well as for determining the extent of those layers in which the pore pressure is less than zero. In addition, a simple method for estimating the pore water pressure profile is provided that also allows predicting its evolution.

Managed aquifer recharge operations are often conducted in near-bank areas to regulate water resources or reduce seawater intrusion. Yet little is known about the influence of surface water level fluctuations at different temporal scales on MAR performance. A generalized conceptual model was developed based on an investigation site in Western China as a basis to simulate the response surface water level fluctuations on the water table, artificially recharged water lens (formed by the artificially recharged water), groundwater flow paths and average travel times (which is an important control on how quickly contaminants are flushed out of aquifers), and the discharge of the artificially recharged aquifer during the surface water level fluctuation. The results showed a fluctuating groundwater table in the artificially recharged near-bank aquifer under the influence of surface water level fluctuations. The peak values of the increment of the groundwater table induced by artificial recharge decreased with the increase of the period and amplitude of surface water level fluctuation, but the trough values of the increment of water table increases with that. The penetration depth of surface water into the aquifer with a fluctuating surface water level leads to a decreasing increment of the groundwater table which follows a power law. The fluctuating surface water level leads to dynamic changes of artificially recharged water lens morphology and a thinner artificially recharged water lens. A mixing zone of recharged water and ambient water could be found in the artificially recharged near-bank area, which is expected to lead to modifications in the geochemical conditions in the artificially recharged near-bank aquifer. A longer period of surface water level fluctuation leads to a longer average travel time, but the larger penetration depth of surface water and amplitude lead to a shorter average travel time. The peak discharge of the near-bank aquifer was found to decrease with the period of surface water level fluctuation, but it increases with penetration depth and amplitude. This study is important in providing insights into the performance of near-bank managed aquifer recharge with respect to surface water level fluctuation.

Aquifers are under over exploitation in other to meet up the demands for portable water, irrigation purposes and industrial uses. A lot of mechanisms take place during this recharging process. Recharging is done in three main ways, which are infiltration methods, direct injection method and filtration methods (J. Casanova et al). The principal objective of MAR in a coastal aquifer is to favor the hydraulic barrier, hence preventing or reducing the intrusion of saltwater and pollutants from the seawater into the aquifer (Casanova et al. 2007, 2008).

Drylands regions of the world face difficult issues in maintaining water resources to meet current demands which will intensify in the future with population increases, infrastructure development, increased agricultural water demands, and climate change impacts on the hydrologic system. New water resources evaluation and management methods will be needed to assure that water resources in drylands are optimally managed in a sustainable manner. Development of water management and conservation methods is a multidisciplinary endeavor. Scientists and engineers must collaborate and cooperate with water managers, planners, and politicians to successfully adopt new strategies to manage water not only for humans, but to maintain all aspects of the environment. This particularly applies to drylands regions where resources are already limited and conflicts over water are occurring. Every aspect of the hydrologic cycle needs to be assessed to be able to quantify the available water resources, to monitor natural and anthropogenic changes, and to develop flexible policies and management strategies that can change as conditions dictate. Optimal, sustainable water management is achieved by cooperation and not conflict, thereby necessitating the need for high quality scientific research and input into the process.

Treated municipal wastewater is used as an input water source for recharge of groundwater using the Soil Aquifer Treatment (SAT) method. The aim of this study is to assess the treated waste water quality performance before and after SAT by using short term soil column development for aquifer recharge applications. The water quality parameters considered during, before, and after SAT are Biological Oxygen Demand, pH, Total Suspended Solids (TSS), Nitrite and Nitrate. The quality of effluents is improved after passage through the soil layers in the soil columns. The final effluent quality from the soil columns of the different sites show different performance percentages. The infiltration rate varied in all soil columns due to development of clogging layer at the top of the soils.

This study shows the robustness of subsurface storage using sand dams under long‐term climate change for the Kitui District in Kenya. Climate change is predicted to enhance potential evaporation through an increase in average temperature of about 3°C. Even though average precipitation will also increase, approximately 13%, the net water availability is projected to decrease in the future, about 1 and 34% in the seasons November to March and April to October, respectively. This study shows that under current climate conditions, total storage in the 500 sand dams currently developed in Kitui captures only 1.8 and 3.8% from the total runoff generated during the November–March and April–October seasons, respectively. These numbers increase to 3 and 20% of total available water for the year 2100 for the November–March and April–October seasons, respectively. Hence, downstream water shortages can be expected under climate change in the April–October season. An additional water consumption...

Water recycling via aquifers has become a valuable tool to augment urban water supplies in many countries. This study reports the first use of passive samplers for monitoring of organic micropollutants in Managed Aquifer Recharge (MAR). Five different configurations of passive samplers were deployed in a stormwater treatment wetland, groundwater monitoring wells and a recovery tank to capture a range of polar and non-polar micropollutants present in the system. The passive samplers were analysed for a suite of pesticides, polycyclic aromatic hydrocarbons (PAHs) and other chemicals. As a result, 17 pesticides and pesticide degradation products, 5 PAHs and 8 other organic chemicals including flame retardants and fragrances were detected in urban stormwater recharging Aquifer Storage and Recovery (ASR) and an Aquifer Storage Transfer and Recovery (ASTR) system. Of the pesticides detected, diuron, metolachlor and chlorpyrifos were generally detected at the highest concentrations in one or more passive samplers, whereas chlorpyrifos, diuron, metolachlor, simazine, galaxolide and triallate were detected in multiple samplers. Fluorene was the PAH detected at the highest concentration and the flame retardant Tris(1-chloro-2-propyl)phosphate was the chemical detected in the greatest abundance at all sites. The passive samplers showed different efficiencies for capture of micropollutants with the Empore disc samplers giving the most reliable results. The results indicate generally low levels of organic micropollutants in the stormwater, as the contaminants detected were present at very low ng/L levels, generally two to four orders of magnitude below the drinking water guidelines (NHMRC, 2011). The efficiency of attenuation of these organic micropollutants during MAR was difficult to determine due to variations in the source water concentrations. Comparisons were made between different samplers, to give a field-based calibration where existing lab-based calibrations were unavailable.

Water has prominence over all the usable natural resources to humankind due to its very significance to human life. Approximately, 70% of Ghana's populace relies on groundwater exploitation for freshwater consumption. Managed aquifer recharge is capable of sustaining water resources for all livelihood activities. Underperformance of MAR systems is often due to site-specific hydrogeological conditions turning out to be less favorable than anticipated. This study evaluates the site-specific conditions for MAR sites identification in granitic aquifers, integrating in situ hydrogeological factors and GIS-MCDA. One hundred and twenty-one datasets from different boreholes comprising hydro geophysics, borehole drilling and pump test reports were used. The constraint mapping results indicate 92% suitable for MAR application within the study area, implying available enormous bare lands for flooding recharge technique. The suitability analysis discloses that 48 and 51% of the studied area fall within very high and high suitable zones, respectively, showing convincing and great potential to support infiltration ponds for MAR technology application. The valuable information provided through this study can serve as a guide for MAR implementation and for sustainable groundwater resources management within the Upper East region of Ghana.

A quantitative microbial risk assessment (QMRA) was performed at four managed aquifer recharge (MAR) sites (Australia, South Africa, Belgium, Mexico) where reclaimed wastewater and stormwater is recycled via aquifers for drinking water supplies, using the same risk-based approach that is used for public water supplies. For each of the sites, the aquifer treatment barrier was assessed for its log 10 removal capacity much like for other water treatment technologies. This information was then integrated into a broader risk assessment to determine the human health burden from the four MAR sites. For the Australian and South African cases, managing the aquifer treatment barrier was found to be critical for the schemes to have low risk. For the Belgian case study, the large treatment trains both in terms of pre-and post-aquifer recharge ensures that the risk is always low. In the Mexico case study, the risk was high due to the lack of pre-treatment and the low residence times of the recharge water in the aquifer. A further sensitivity analysis demonstrated that human health risk can be managed if aquifers are integrated into a treatment train to attenuate pathogens. However, reduction in human health disease burden (as measured in disability adjusted life years, DALYs) varied depending upon the number of pathogens in the recharge source water. The beta-Poisson dose response curve used for translating rotavirus and Cryptosporidium numbers into DALYs coupled with their slow environmental decay rates means poor quality injectant leads to aquifers having reduced value to reduce DALYs. For these systems, like the Mexican case study, longer residence times are required to meet their DALYs guideline for drinking water. Nevertheless the results showed that the risks from pathogens can still be reduced and recharging via an aquifer is safer than discharging directly into surface water bodies.

In this study, we attempt to identify zones suitable for artificial-recharge in Abu Dhabi using (GIS). The solution has started by employing least cost analysis to produce two cost-impact parameters for expected pollution originating from septic tanks and pesticides. Data used includes hydraulic gradient and distribution map of source point pollutions. Cost analysis considered the hydraulic gradient as a friction layer to calculate the accumulative cost-impact over the whole basin and it produces a mapping of high/low cost layers. The high hydraulic gradient is considered the low cost for pollution associated with groundwater. Next, multi criteria of Fuzzy Overlay GIS technique have been introducing in order to integrate the producing cost impact parameters together with Hydrogeomorphic and geologic Indexes based on Analytical Hierarchy Process (AHP) to finally develop Suitability mapping showing the best choice for sites adapted for artificial recharge. The cartography of the groun...

A utilização de técnicas de MAR (managed aquifer recharge, em nomenclatura inglesa ou gestão de recarga induzida de aquíferos) visa armazenar água em aquíferos durante períodos de excedentes podendo ajudar a resolver posteriores desafios de escassez de água e, assim, melhor gerir a variabilidade temporal da disponibilidade de água. Além disso, a qualidade da água pode ser melhorada através da sua circulação pelo meio poroso até ao aquífero, como resultado de processos químicos e biológicos, para além da própria diluição. Nesse contexto, a recarga induzida de aquíferos pode ser um importante contributo para resolver a crise de água da Europa, ligando o uso de excedentes hídricos com a reutilização de água e a gestão de recursos hídricos.

The accelerated growth of water demand globally calls for promising solutions in the field of water management. Managed aquifer recharge (MAR) systems are among the solutions that are capable of increasing water supply and improving water quality through natural attenuation processes. Along with hydrogeologic considerations and institutional feasibility assessments, economic analysis is essential when evaluating MAR projects. This study is the first one to provide an economic feasibility assessment of a MAR scheme in Poland by performing a cost-benefit analysis (CBA) combined with a contingent valuation study to identify the willingness-to-pay, sensitivity analysis to address uncertainty regarding the realisation of benefits and costs together with expert assessment of socio-economic risks associated with the MAR scheme implementation. The results suggest that the total economic value of the MAR scheme’s extension (which includes both use and non-use benefits) exceeds the costs of p...

After the nuclear weapons testing in the 1950s and 1960s, the atmospheric tritium levels have almost returned to natural levels (pre-1950 levels), which means that tritium is becoming more effective in determining transit times in hydrological systems. It has also been demonstrated that tritium is a non-reactive noble gas and in water is not subject to chemical reactions, absorption, or dissolution/precipitation processes, so it is conservative of the geochemical fingerprint of the source. In addition, it is used as an effective tracer of water contamination by landfill leachate, allowing to detect mixing percentages of the leachate up to levels not achievable with normal chemical analyses (less than 1 %). The purpose of the present work is to deepen the knowledge of the hydrogeochemical characteristics of the aquifers in the pedemontana area of the Venetian plain, and to formulate a conceptual framework of underground water circulation, aimed at understanding phenomena of contamination by toxic metals, harmful to human health. Tritium concentration analyses were performed on selected samples of groundwater collected in different wells in the south part of Treviso city to correlate the young age of the water recharge. The abundance of young waters, in fact, indicates a vulnerability of the aquifer to climate change with respect to possible contributions of surface waters, in particular to prolonged drought periods which could induce salinization dynamics.

This study investigates the determination of aquifer parameters using step discharge tests to evaluate well performance for effective aquifer management. Single-well tests provide estimates of transmissivity in cases where cost and access preclude multi-well pumping tests. The study focused on two wells around the KNUST campus, determining aquifer loss, well loss, well efficiency, specific capacity, yield, and transmissivity. Results show transmissivity values of 3.21 m²/day and 5.82 m²/day, well efficiencies of 88.61% and 98.45%, and specific capacities of 2.89 m²/day and 3.03 m²/day for the two wells respectively.
