“…The construction of artificial recharge structures, such as recharge pits in existing surface waters, construction of percolation ponds, and farm ponds, will support freshwater recharge in the shallow aquifers of the study area and increase the groundwater levels that can be used for irrigation [65]. In addition, the implementation of flood extraction methods, such as the construction of retention dams and the application of surface water in the ephemeral rivers of the study area, can increase the infiltration of freshwater for groundwater recharge [66,67].…”

Ramanathapuram is a drought-prone southern Indian district that was selected for conducting a hydrogeochemical study. Groundwater samples from 40 locations were collected during January 2020 (pandemic interdiction according to COVID) and January 2021. The hydrogeochemical properties of the groundwater samples were evaluated and compared with drinking water regulations to assess their water quality. The order of cation dominance was as follows: Na+ > Ca2+ > K+ > Mg2+ in January 2020 and Na+ > Ca2+ > Mg2+ > K+ in January 2021 with respect to the mean value. The order of anion dominance was as follows: Cl− > HCO3− > SO42− > NO3− > F− in January 2020 and Cl− > SO42− > HCO3− > NO3− > F− in January 2021 with respect to the mean value. In the study area, the southern coastal region was identified as a groundwater-polluted zone through spatial analysis based on all analysis results. The irrigation water quality was analyzed using various calculated indices, such as Na% (percent sodium), SAR (sodium absorption ratio), PI (permeability index), MgC (magnesium risk), RSC (residual sodium concentration), and KI (Kelly ratio), demonstrating the suitability of the groundwater for irrigation in most parts of the study area. This was also confirmed by the Na% vs. EC Plot, USSL, and Doneen’s Plot for PI. In addition, the WQI results for drinking water and irrigation confirmed the suitability of the groundwater in most parts of the study area, except for the coastal regions. The dominant hydrogeologic facies of Na+-Cl−, Ca2+-Mg2+-SO42−, and Ca2+-Mg2+-Cl− types illustrated by the Piper diagram indicate the mixing process of freshwater with saline water in the coastal aquifers. Rock–water interaction and evaporation were the main controllers of groundwater geochemistry in the study area, as determined using the Gibbs plot. Ion exchange, seawater intrusion, weathering of carbonates, and the dissolution of calcium and gypsum minerals from the aquifer were identified as the major geogenic processes controlling groundwater chemistry using the Chadha plot, scatter plot, and Cl−/HCO3− ratio. Further, multivariate statistical approaches also confirmed the strong mutual relationship among the parameters, several factors controlling hydrogeochemistry, and grouping of water samples based on the parameters. Appropriate artificial recharge techniques must be used in the affected regions to stop seawater intrusion and increase freshwater recharge.

“…Since the industrial revolution, natural and contaminated waters have been extensively investigated throughout the globe. The site-specific development has damaged and continues to pollute the groundwater system in multiple locations across India (1)(2)(3)(4) . Due to a lack of surface water resources, economic development in arid and semiarid areas is increasingly dependent on groundwater, which provides high-quality water for drinking, household, agricultural, and industrial purposes.…”

Objectives:The current study shows the magnitude of changes in land use and land cover (LULC) in the Ambattur Zone from 1990 to 2021 and examines its impact on groundwater quality through the Gibbs diagram, Piper diagram, multivariate statistical analysis, and water quality index (WQI) for drinking. Methods: Landsat images were collected to derive the LULC images through the supervised classification approach. Groundwater samples were collected from 31 wells for two seasons and analyzed for the hydrogeochemical study. Gibbs, Piper, multivariate statistical analysis and WQI were done to evaluate the groundwater quality for drinking purpose and to study the hydrogeochemical characteristics. Findings: The results show that barren land decreased from 7.4 to 4.31 km 2 , whereas, built-up land expanded from 21.37 to 24 km 2 . Compared to barren and built-up regions, water and vegetation land haven't changed much. LULC change analysis required assessing Ambattur groundwater quality. Physico-chemical investigations and ionic concentrations show that Ambattur industrial zone groundwater is contaminated and unsafe for human consumption. WQI shows that 60% of groundwater is unfit in both seasons. Evaporation and rock-water interaction alter the area's groundwater chemistry. Hydrogeochemical facies diagrams show alternating alkaline and alkali dominance, as well as strong and weak acids. According to correlation matrices, all analytical parameters except pH have a positive correlation. Four basic components and a cluster contribute to understanding industrial pollution. Novelty: (i) The present study integrates LULC changes and hydrogeochemistry for the evaluation of groundwater quality. (ii) The comprehensive approach of analyzing LULC changes in conjunction with evaluating the groundwater geochemistry gives new insights in groundwater management for the long-term development of any region. https://www.indjst.org/
