“…Heavy metals and As contamination in groundwater systems have been reported in several Indian cities (Ravindra and Mor, 2019;Shaji et al, 2021).ji For instance, several villages of Chandigarh were reported to be contaminated with heavy metals/-metalloids such as Cadmium (Cd), Nickel (Ni), Lead (Pb) and Zinc (Zn) (Ravindra and Mor, 2019). In addition to urban cities, surface and groundwater resources in pristine landscapes of the north eastern region are also reported with excess concentrations of heavy metals and As (Zonunthari et al, 2023a;Zonunthari et al, 2023b;Laishram and Kshetrimayum, 2019;Lahkar and Bhattacharyya, 2019). The ingestion of these heavy metals/-metalloids contaminated groundwater can cause various human health hazards like immunodeficiency, osteoporosis, neurotoxicity, kidney and other organ failures, and cancer (Ravindra and Mor, 2019;Gupta et al, 2023).…”

The increase in population and rapid industrial development have resulted in surface water pollution that stresses groundwater resources to ensure sustainable consumption and human well-being. The present study was aimed to assess the physico-chemical characteristics and heavy metal concentration of groundwater in Aizawl city. The study also seeks to determine the indicator parameters of water quality through analysis of variance (ANOVA) and correlation coefficient in relation to physico-chemical properties. The results revealed that all physico-chemical parameters were within the regulatory standards, except turbidity (80.9 NTU) and phosphate (0.6365 mg/L). Trace amounts of Zinc (Zn) and Copper (Cu) were also present; however, Iron (Fe) and Manganese (Mn) slightly exceeded (Fe: 1.162 mg/L; Mn: 0.6892 mg/L) the permissible limit. Statistically, two-way ANOVA revealed that temperature, chloride, total alkalinity (TA), total hardness (TH), calcium, and dissolved oxygen (DO) were significant (p<0.001) both between sites and seasons. Further, TH showed positive and significant correlation with total dissolved solid (TDS) (R2=0.792), chloride (R2=0.52), TA (R2=0.62), calcium (R2=0.88), and Zn (R2=0.61). Conversely, DO demonstrated negative and significant correlation with turbidity (R2=-0.73), chloride (R2=-0.52), phosphates (R2=-0.70), ammonia (R2=-0.81), and Mn (R2=-0.58). These results indicate that the analysis of TH and DO can serve function as proxies for indirectly indicating the presence and concentrations of the other correlated water quality parameters. Thus, TH and DO act as indicator parameters for water quality in holistic groundwater monitoring in Aizawl. The identification of water quality indicator parameters can play a key role in future research for cost-effective, rapid, and seasonal groundwater monitoring to ensure the sustainable management of this resource.

The present investigation attempts to assess the harmful heavy metals and uranium exposure in shallow aquifers of the highest populated district Nagaon in the central Brahmaputra floodplain of Assam, India. Spatial distribution using the inverse distanced weighted interpolation method in Arc GIS, various pollution indices and health risk assessment indices pooled with statistical studies were employed to appraise the pollution scenario and potential health risk. The contamination degree index for the three locations was 14.09, 21.43 and 25.95, signifying a considerable degree of contamination. The excess cancer risk due to the radioactivity of uranium in adults and children of Nagaon district is negligible compared to the prescribed limit of 1.67×10-4 set by the Atomic Energy Regulatory Board. The average concentration of the analyzed heavy metal follows the order Mn > Fe > Zn > Cu > Ni > U > Pb > Cr > Cd. The notch box plot study reveals that the risk associated with the ingestion of water contaminated with heavy metals is higher than the dermal absorption. The HQIngestion of manganese in children shows a higher range (0.003-6.85) than in adults (0.002-4.12), with a median value of 0.14 compared to 0.08 in adults. Both adults and children are vulnerable to non- carcinogenic risks, and the risk is higher in children than in adults.
