“…Yadav and Mishra (2014) observed the same minimum or maximum results for groundwater pH, which supports our investigation. The salinity risk and quality of groundwater can be determined with the help of electrical conductivity (Mahalakshmi and Rivachandrabose, 2021;Rao, et al, 2019). During the present study period, ECs were observed in the range of 370-5260 µS/cm (Table 3).…”

Groundwater is an important resource and approximate 80% of the world’s population depends solely on it to satisfy their needs. In the present investigation groundwater quality was assessed using WQI. For the same parameters viz, temperature, pH, conductivity, DO, alkalinity, TDS, sulphate, fluoride, bicarbonate, chloride, uranium, total hardness, calcium and magnesium hardness were assessed during post monsoon period in November 2021 in the Chandrapur region. For conducting this research total 116 groundwater samples were collected from different hydrological stations for the assessment of WQI. WQI is an important tool to assess quality of water for drinking and is classified as excellent to unsafe, i.e., 0-100 score. In this investigation WQI was found to be in the range between 27.63-674.56 exceeding both minimum and maximum score. The results of the present investigation showed that only 5.17% of water is safe for drinking,18% of water indicated poor water quality, 15% of water has very poor water quality and 77% of water is unsuitable for drinking purpose and proper treatment is required before use. During this investigation uranium in groundwater was also assessed considering its chemotoxical and radiological effects on human health. The chemotoxical and radiological effects were analyzed adopting standard equations given by USEPA. The radiological risk of mortality and morbidity was found to be 1.37E-05-1.47E-05, respectively. Thus, presence of uranium was noted and radiological risk was found to be below the permissible limit of AERB standard. The chemical toxicity of average value of Lifetime Average Daily Dose (LADD) and Hazard Quotient (HQ) was observed 0.315 and 0.00571, respectively and chemical toxicity of LADD was found to be in 8.62% sample population and above the permissible limits which can affect human health and can have kidney toxicity, bone and lung toxicity.

“…The pH of the samples ranged between 7.9 and 6.11. The pH values in the pre-monsoon were higher in samples from the pre-monsoon of 2022, which might be due to the high temperature in the pre-monsoon (Rao and Krishna, 2019). The standard limits set by WHO and NDWQS for pH are 6.5-8.5.…”

Groundwater is a crucial natural resource for sustaining human life, agriculture, and ecosystems worldwide. In many Asian countries, including Nepal, groundwater has emerged as a dependable source of water, particularly in areas where surface water is scarce or unreliable. For instance, in Bhaktapur Municipality (BM), Nepal, groundwater has been contributing around 50–60% of the total water supply. However, over the past few years, extensive extraction, alterations in the land use pattern, and other anthropogenic interventions have posed serious threats to this highly valuable resource. As such, groundwater monitoring is an essential primary step for understanding the status of the groundwater resource. Meanwhile, the Water Quality Index (WQI) is an effective tool that can turn complex water quality data into simplified information that is understandable and usable by the public. This study aimed to understand the groundwater levels and further comprehend the groundwater quality using the WQI of the BM. The groundwater level data and water samples were collected from 24 spatially distributed wells of the BM in the post-monsoon of 2021 and the pre- and post-monsoon of 2022. Laboratory analysis was carried out to determine the nine physico-chemical water quality parameters, and the obtained parametric values were compared with those of the World Health Organization (WHO) and the National Drinking Water Quality Standard (NDWQS). The results show deeper groundwater levels in the core area than the periphery, and the water quality getting poorer from post-monsoon 2021 to post-monsoon 2022. The EC, TDS, pH, phosphate, chloride, and hardness of most of the samples were within the permissible limits of WHO and NDWQS, whereas the turbidity, ammonia, and alkalinity of many samples exceeded the permissible limits. Average WQI revealed that the majority of the samples were unsuitable for drinking and suitable only for household and irrigation purposes. This study provides insights into managing water demands, addressing issues of water scarcity, and highlighting the urgent need for additional research and policymaking to improve drinking water quality and the sustainability of groundwater management in BM.
