This study examines the factors and mechanisms contributing to Fˉ and U co-occurrence in the region's aquifers to enhance the understanding of the contaminants' behaviour. Fˉ and U concentrations were higher in shallow aquifers (&lt;60 m) compared to deeper (&gt;60 m), and both the contaminants surpassed their respective permissible limits under excess EC, TDS, Clˉ, NO₃ˉ, SO₄²ˉ, Na⁺, and K⁺ levels. Elevated EC and TDS and their strong correlation with U and Fˉ suggest high salinity facilitated mobilization and co-contamination by increasing ionic strength and competitive behaviour through ion exchange mechanisms. Additionally, scanty precipitation, enhanced evapotranspiration, and aridity were significantly correlated to Fˉ and U, highlighting that these meteorological variables positively influence this co-contamination, particularly in the Malwa region. The mixed chemical composition of the groundwater emanated from rock-water interaction and evaporation, which further increased Fˉ and U and facilitated their co-occurrence. U existed predominantly as UO₂(CO₃)₂²ˉ and UO₂(CO₃)₃⁴ˉ (95%), which corroborated with a strong positive correlation with HCO₃ˉ, whereas fluoride existed mainly as free Fˉ (90%). The findings of this work will help the scientific community to address similar issues in other arid and semi-arid regions globally and investigate the potential synergistic effect and health risks associated with the co-occurrence of Fˉ and U in the groundwater.</p></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"26 ","pages":"Article 101283"},"PeriodicalIF":4.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141846116","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}

The primary source of water in Kathua is groundwater, which is widely used for industrial, agricultural, drinking, and building purposes. The groundwater system is changing significantly both in terms of quantity and quality in the study area due to recent industrial and infrastructural developments. Thus, 40 groundwater samples were collected from different wells in the pre-monsoon season, May 2022, and analyzed for physicochemical variables to determine the impact of geogenic and anthropogenic activities on the groundwater. The drinking groundwater quality appears to be excellent to good. Of the variables that were examined, two—TH and HCO₃—had concentrations higher than the recommended limits of the BIS and WHO guidelines. Groundwater contains alkaline earth metals and weak acids, and its hydrochemistry is controlled by rock‒water interactions (silicate weathering or cation exchange and reverse-ion exchange processes). Several parameters (electrical conductivity, sodium percentage, sodium adsorption ratio, permeability index, magnesium adsorption ratio, residual sodium carbonate, and the Kelly’s ratio) were used to evaluate groundwater suitability for irrigation. The permeability index, magnesium adsorption ratio, and residual sodium carbonate indicate that the groundwater of a few samples is unsuitable for irrigation purposes. Land use/land cover (LULC) change analysis was used to determine the potential impacts of LULC changes on groundwater. Anthropogenic interventions are a major cause of LULC changes that are considerably reducing groundwater recharge zones, increasing surface runoff, and artificially polluting groundwater through domestic and industrial wastes, according to the LULC analysis conducted using satellite data for the year 2017 and 2022. Therefore, to minimize the effects of LULC on groundwater, prompt action must be taken, requiring regular monitoring of groundwater quality and LULC changes. The results of the study may be useful to the general public, farmers, and policy makers in the sustainable development and management of groundwater.</p></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"26 ","pages":"Article 101303"},"PeriodicalIF":4.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142012887","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}

Employing advanced geo-accumulation indices and crystal phase differentiation methods, the study unveils the intricate metamorphosis of heavy metals and mineralogical composition, tracing the transformative journey from leachate to sediments. Noteworthy revelations emerge, particularly in the striking associations between heavy metals and the mineralogical composition, which encompasses primary and secondary minerals (calcite, quartz, and Fe–Mg oxides). These findings underscore the acceleration of weathering processes within this distinctive geological milieu. The 'geo-accumulation index' exhibits pronounced elevations in proximity to the landfill site, with persistence downstream, reliant upon the evolving weathering and accumulation dynamics. The lower reaches of the study area have higher concentrations of various heavy metals (Fe, Mn, Zn, Cr, Cu, Ni, Co, Hg, As, and Cd). These heavy metals are primarily sequestered within silt-dominated sediments conquered by augite, olivine and plagioclase minerals.

Xenobiotic compounds such as heavy metals, dyes, polycyclic aromatic hydrocarbons (PAHs), oil spills, pharmaceuticals' active compounds (PhACs), and agrochemicals show detrimental effects on the environment through long-term persistence causing biomagnification, pollution, etc. In the last few decades, researchers have dedicated themselves to developing different physical and chemical remediation methods, although facing several drawbacks and challenges and searching for eco-friendly alternatives like bioremediation. Conventionally bioremediation utilizes biological agents such as plants, microbes, fungi, etc. To reduce environmental pollutants' effects. Although conventional bioremediation has certain limitations, SMS (spent mushroom substrate) has recently drawn great attention worldwide because of its low cost, environment-friendly nature, easy availability, and higher remediation efficiency. Scientists have used waste mushroom SMS for bioremediation purposes for various xenobiotic compounds. Therefore, the present review's foremost aim is to encompass the role of mushroom SMS in the remediation of xenobiotic compounds, techniques for studying the adsorbent properties of SMS, factors affecting the adsorption process, and the probable mechanism involved in its remediation process. This study has noteworthy findings implying that eco-friendly multi-purpose SMS has great efficacy against environmental contaminants, and its removal efficiency gets increased with combinatorial approaches like SMS amendments (biochar, etc), phytoremediation, rhizoremediation, and nanoremediation.

However, to identify unreported springs and shallow water upwelling zones, it is essential to understand the factors that control spring localization. In a crystalline basement, as in Sri Lanka, without a sedimentary cover, faults and fractures provide the only far-reaching fluid pathways and springs commonly emerge at fault/fracture intersections. While surveying cold and hot water springs in Sri Lanka, it was observed that all springs probed were located at the edge of alluvium. In order to gain insight into this relationship, we performed a topographic and geomorphological analysis was conducted utilizing remote sensing, geological and soil maps, and geological mapping in the field. The results of our analysis of 27 springs indicate that their localization is controlled by fault intersections, non-permeable clay in the alluvium and laterite, and the chemically weathered surface of the bedrock. Furthermore, the constant discharge rates observed over the years and isotope analysis suggest that the springs are part of a tens-of-kilometer-wide regional groundwater system. Based on these results, we propose a conceptual model in which water rises at fault intersections from depth until it reaches the base of the alluvium where up to several meters thick clay with low to zero permeability further inhibits vertical flow forcing the water to spread laterally. Along the alluvium clay boundary with the more permeable weathered bedrock, the water continues its path to the surface. The localization of springs differs from that of fault intersection by tens of meters, with the potential for mixing between shallow and deep groundwater. This observed effect of alluvium and their contact boundaries on spring localization has not been reported for Sri Lanka. Consequently, discharge rates may be significantly increased if the fault intersections are specifically targeted by shallow drilling.</p></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"26 ","pages":"Article 101289"},"PeriodicalIF":4.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352801X24002121/pdfft?md5=75b283875a1fe808107e6fee64fa1176&pid=1-s2.0-S2352801X24002121-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141960264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By merging multiple groundwater contributing theme layers, a leading-edge information-based multiparametric analytical hierarchy process (AHP) was applied to define the groundwater prospective areas. By systematically assigning weights to every subject-specific layer and feature, the subject matter layers of geology, geomorphology, drainage density, slope, soil properties, landuse/landcover, rainfall distribution, hydraulic conductivity, transmissivity, curvature, proximity to surface water bodies, and elevation were generated and used for groundwater potential map generation.

The study employs a systematic approach integrating watershed modeling using the Soil and Water Assessment Tool (SWAT), multi-criteria decision analysis (MCDA), and constraint mapping techniques. Initially, the SWAT model evaluates water availability for MAR, followed by an MCDA-AHP method to identify optimal sites based on ten spatial parameters encompassing technical, economic, and environmental criteria. Furthermore, the study employs constraint mapping to refine site suitability assessments and sensitivity analysis to gauge the robustness of the results. The SWAT analysis revealed substantial variation in runoff volumes among the eight sub-basins, ranging from 8.34 m³/s to 136.28 m³/s, indicating significant availability of source water for MAR.
