In order to determine the spring water quality, hydrogeochemical processes, and seasonal changes, thirty-six samples from nine locations in four seasons (2021–2023) were collected and analysed for physicochemical constituents, heavy metals, and stable isotopes (δ<sup>18</sup>O and δ<sup>2</sup>H). The findings demonstrate that a mixture of processes, such as silicate and carbonate weathering through ion exchange and reverse ion exchange processes, regulate the spring water chemistry. The geochemical evolution of spring water is primarily driven by rock weathering, with 86% of the samples exhibiting a Ca.Mg-HCO<sub>3</sub> water type. Most parameters show insignificant seasonal changes except for SiO<sub>2</sub> (p = 0.002), Al (p = 0.007), Co (p = 0.002), Cu (p = 0.00), Li (p = 0.00), Mo (p = 0.00), and Pb (p = 0.00). The isotopic data suggests meteoric origin of spring water, with δ<sup>18</sup>O and δ<sup>2</sup>H values ranging from −8.91‰ to −7.65‰ and −62.7‰ to −51.6‰ (pre-monsoon) and −9.71‰ to −7.86‰ and −63.9‰ to −51.3‰ (post-monsoon), aligning with the local meteoric water line (δ<sup>2</sup>H = 7.73 × δ<sup>18</sup>O+10.45; r<sup>2</sup> = 0.99). The EWQI and HPI suggest excellent spring water quality in 89%–100% of samples. Among the heavy metals, arsenic poses a potential non-carcinogenic risk in 11%–44% of spring water samples for adults and children. Similarly, arsenic (33%–56%) and nickel (44%–78%) present significant carcinogenic risks, exceeding the acceptable limit of 1 × 10<sup>−4</sup>. Overall, the spring water quality is adequate and primarily driven by natural processes, but the levels of As and Ni are in the critical range for human health.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"29 ","pages":"Article 101411"},"PeriodicalIF":4.9,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143101816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Monte Carlo Simulation was employed to model probabilistic risk and identify the factors contributing most to arsenic-related health risks. Limited probabilistic risk assessments have been conducted in this high-risk region. The findings revealed a higher mean As levels in drinking water (24.5 μg/l) and rice grain (201 μg/kg) surpassing the acceptable limit, whereas, pulses (26.5 μg/kg) were considered to be safe. Besides, As accumulation in chronic toxicity biomarkers of the studied population was also found higher (100% and 96% for hair and nails, respectively) than the threshold values. Furthermore, a significant correlation was observed between As ingestion and biomarker accumulation, reflecting an age-dependent increase in As levels in hair and nails. However, gender was found to have no substantial impact on As accumulation in chronic biomarkers. Among all the sources, rice grain was found as the primary route of As exposure followed by drinking water and pulses. The total estimated daily intake of As (EDI<sub>Total</sub>) was found to be highest in adult males, correlating with their heightened carcinogenic risk (CR), followed by females and children. Non-carcinogenic risks (NCR) were notably high among children and according to the sensitivity test result, As concentration in ingestible sources was found to be the most significant component contributing to the CR and NCR followed by exposure duration (ED). These findings underscore the need for immediate interventions in water management and agricultural practices to reduce As exposure and prioritise the necessity for As-safe drinking water to protect human health from its toxic consequences.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"29 ","pages":"Article 101410"},"PeriodicalIF":4.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143101815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Managed Aquifer Recharge (MAR)- groundwater recharge and underground water storage for later use or environmental support presents a viable alternative for water storage and may provide an effective tool for coping with such challenges. However, the potential area where MAR can be feasibly implemented has not been identified. This study mapped MAR feasibility using a Geographic Information System-based Multi-Criteria Decision Analysis (GIS-MCDA) and assessed MAR potential in Africa. The methodology focused on three key pillars of MAR feasibility: intrinsic suitability based on biophysical parameters, water source availability, and water demand. Maps responding to these pillars were developed and combined to create a composite MAR feasibility map. Results show that 18% of the continental area falls into the low feasibility class, 73% into the moderate feasibility class, and 7% into the high feasibility class. The feasibility map was validated against 17 existing MAR schemes in Africa, demonstrating a good correlation between their locations and areas with MAR potential. Results of sensitivity analysis of criteria weights of the biophysical parameters show that geology is the most influential criterion, followed by slope. In general, this first feasibility assessment shows good potential for MAR implementation in Africa. Therefore, MAR should be considered prominently among other water storage options for resilience building in Africa and policymakers should ensure adequate resource allocation for its implementation.

The modified water quality index (MWQI) was employed to assess the health risks linked to drinking water quality. The overall water quality index suggests that the water is safe to drink, Thus, 81 % of the groundwater is suitable for drinking, while 7.1 % is considered poor and unsafe for drinking.

The concentrations of trace elements in the groundwater of each aquifer type were below the MCL of USEPA, however, excessive Sr concentrations were evident mostly in the evaporite-rich aquifer.
