Summary: The Kandivalasa river sub-basin in the Northern Eastern Ghats of India is mainly composed of Khondalitic rocks. A groundwater flow model with two conceptual layers was developed using Visual MODFLOW for the period 2013-2016. The model predicts that if the extraction rate continues to increase by 2% per year, significant dry cells will develop in the study area starting from 2021, with an even greater extent by 2036. Mitigation measures such as reducing groundwater pumping and using surface water more efficiently are recommended.

Summary: Rapid groundwater withdrawal poses a threat to existing groundwater resources globally, leading to reduced groundwater levels and disrupted hydrogeochemical processes. This study evaluated the suitability of groundwater in Bemetara District, India for drinking purposes, using the water quality index (WQI) method and principal component analysis (PCA). The findings indicated degraded groundwater quality, with high levels of total dissolved solids and sulfate ions exceeding acceptable limits. The study highlights the need for treatment of groundwater in certain areas and provides important data for the design of sustainable groundwater management plans.

Summary: In this study, the hydrogeochemical processes influencing the groundwater geochemistry, potability, and suitability for agriculture in the Tummalapalle area were evaluated. Analysis of 144 borehole locations revealed that the pH, total dissolved solids, and hardness of the groundwater were within acceptable limits. Piper and Chadha charts were used to determine the dominant hydrogeochemical components of the groundwater, and the Gibbs plot analysis indicated that rock aquifer interaction was the major process governing groundwater geochemistry in this region. The water quality index revealed that 55% of the groundwater samples in the Tummalapalle region were suitable for drinking.

Summary: The article explores the application of radon deficit as a tracer of contamination, in order to assess the degree and evolution of NAPL contamination in soil and groundwater. By statistically analyzing radon data, NAPL concentration in groundwater, and the depth of the groundwater table, the factors and attenuation processes affecting the contamination sites are identified.

Summary: This research develops metrics for groundwater quality assessment using a multi-proxy approach. The study collected and analyzed groundwater samples from Tamirabarani river basin, comparing them with national and international standards. The results show higher concentrations of calcium and chloride ions, possibly due to regional point sources and agricultural practices. Principal component analysis indicates that the post-monsoon season explains a significant proportion of the variance. The dominance of certain anions and cations suggests significant degradation of groundwater quality in the region, resulting from urban pollutants and unprotected river sites.

Summary: The study identified three deep groundwater subsystems in the Huai River Basin, with the Ancient Yellow River system having the strongest groundwater renewal ability. Calculation based on stable isotopes and water chemistry data revealed that the deep groundwater renewable ability of Ancient Yellow River, Shaying River, and Guo River are 36%, 22%, and 12% respectively.

Summary: This study evaluates the sources and controlling factors of groundwater contaminants in an agroeconomic region of the Lower Ganga Basin. The findings indicate that the dissolution of fluoride-bearing minerals and semi-arid climate regulate fluoride concentrations in groundwater, while the extensive use of inorganic nitrogenous fertilizers and livestock manure contribute to elevated nitrate levels. The health risk analysis reveals that fluoride exposure is more prevalent in residents of all age groups compared to nitrate, and both contaminants pose higher non-carcinogenic health risks to infants and children.

Summary: This study evaluated the microbiological quality of groundwater from six sub-basins in the upper Choluteca River basin in Honduras and determined the phylogroups of E. coli isolated from these samples. The results showed a high proportion of fecal contamination, indicating that the groundwater in the basin is unsafe for human consumption. Measures should be taken to raise awareness about sanitation and waste management practices.

Summary: The study found a large amount of radon-222 in groundwater of hard rock aquifers, mainly concentrated in the khondalite formation, and high radon-222 activity matched with the location of lineaments. Although no significant correlations were observed between radon-222 activity and depth to water table, groundwater temperature, and electrical conductivity, the presence of high radon-222 activity in groundwater was associated with geological structural features.

Summary: Soils act as a crucial interface between human activities and the environment, requiring conservation and protection. Industrialization and urbanization have led to the release of heavy metals into the environment through exploration and extraction operations. This study analyzed the distribution of six heavy metals in soil samples collected in and around drilling sites, revealing higher pollution levels for certain metals near the drilling sites. Assessment of ecological and health risks demonstrated non-carcinogenic risks due to high concentrations of certain metals, as well as significant carcinogenic risks in the study area. These findings can guide remedial measures and management strategies to mitigate contamination in farming activities.

Summary: This study evaluates the impact of human induced activities on groundwater quality in the Agra-Firozabad industrial belts of Western Uttar Pradesh, Yamuna basin, India. The study finds that the groundwater contains high concentrations of metals and anions, making it unsuitable for industrial use but suitable for agricultural use. Health risk assessment studies show that children consuming this polluted water are more affected than adults. Timely action and strict compliance of regulations are recommended for groundwater management to prevent severe health effects and achieve sustainable development goals.

Summary: India faces a groundwater crisis due to overexploitation and deteriorating quality, driven by rapid urbanization, population growth, and mismanagement. Developing a Groundwater Quality Index using GIS can predict seasonal groundwater quality and inform sustainable water management strategies. The GIS-based Analytic Hierarchy Process model showed the highest prediction accuracy, indicating its reliability for assessing groundwater quality at a river basin scale.

Summary: In recent years, the vulnerability and contamination of groundwater have become more severe. The upper Dwarakeshwar river basin in India used a GIS-based DRASTIC model to assess groundwater vulnerability. Seven intrinsic hydro-geological parameters were considered to determine the magnitude of vulnerability, and the DRASTIC Vulnerability Index (DVI) was used to identify vulnerable zones. The study showed that the depth of water table is the most sensitive parameter for groundwater contamination in the area. The results of this scientific study can assist regional planners and policymakers in sustainable groundwater development and management.
