“…The parameters loading in PC1 governed the nutrient input source from natural sources, while positive loading of parameters in PC2 defined the nutrient input through direct discharge of partially or untreated treated domestic or industrial wastewater into the river ( Mishra and Kumar, 2020 , Kumar et al, 2018 ). During the comparative analysis of parameters loading in PCs at all locations, it was noted that the parameter K, SO 4 , Na, and Cl were positively loaded in PC1, which signified the input of their salts from both natural source through runoff or landslides and anthropogenic agricultural activities (where use of chemical herbicides, fertilizers, pesticides, and mining operations occurs) ( Dalakoti et al, 2018 ).…”

The deteriorating water quality (WQ) of the sacred north-flowing perennial Indian River, Ganga was a serious concern in recent decades for population adjoining to the river and policy planners. The present evaluation attempts to assess the long-term (1989–2016) physiochemical characteristics of WQ of river Ganga at five upstream locations (Uttarkashi, Tehri, Rudraprayag, Devprayag, and Rishikesh) of Uttarakhand, India using comprehensive pollution index (CPI) and environmetrics (PCA and CA). These methods were used to categorize, summarize expensive datasets, and grouping the similar polluted areas along the river stretches. The WQ of river at all the locations were within the good category and most of the physiochemical parameters were well within their acceptable limit for drinking WQ. Considerably, CPI demonstrated the river WQ was in slight pollution range (CPI: 0.40–1.00) in the year 2007 and 2015 at all the five locations. The positive correlation coefficient (R 2 > 0.50) among NO 2 NO 3 , Ca, Na, B, and K indicates the significant contribution of organic and inorganic salts through runoffs from catchments due to weathering of rocks. PCA confirmed the input source of nutrients in the river from both natural and anthropogenic sources. Moreover, the upstream WQ assessed was found to be good as compared to the severely polluted downstream region. Due to COVID-19 and shutdown in the country, reduction of pollution load in the river was observed due to the rejuvenation capability of river Ganga. This information can assist the environmentalist, policymaker, and water resources planners & managers to prepare strategic planning in advance to maintain the aesthetic and cultural value of Ganga river in future.

“…Globally, various water quality indices have been developed for monitoring surface water quality of rivers such as the Weighted Arithmetic Water Quality Index, National Sanitation Foundation Water Quality Index, Comprehensive Pollution Index, Carlson's trophic index, and Canadian Council of Ministers of the Environment Water Quality Index (Batabyal & Chakraborty, 2015;Gupta et al, 2017;Kumar, Sharma, & Rai, 2017;Mishra & Kumar, 2020;Mishra, Kumar, & Shukla, 2016).…”

“…Also, high lead concentrations in groundwater pose significant risks to consumers. Indeed, in most research [36,46,56], it is indicated that increased blood Pb concentration affects behaviour, cognitive performance, postnatal growth, delays puberty and reduces the hearing ability of infants and children. In adults, Pb causes cardiovascular, central nervous system, kidney, fertility, and cancer problems.…”

This study aims to assess the groundwater quality and the origin of water mineralization in an environment with high anthropogenic pressure in the municipality of Treichville. Twenty-one water samples were analysed to determine the quality. Kruskal-Wallis nonparametric test, Mann-Whitney test, Kohonen algorithm, and water table building were used to determine the factors influencing the mineralization. The results showed that the well's water contains chemical and bacteriological elements whose concentrations are higher than the standards authorized by the World Health Organization (WHO). Thus, high levels of nitrate (peak = 173.1 mg L −1), phosphate (peak = 1.03 mg L −1), lead (peak = 2.987 mg L −1), and Escherichia coli (peak = 2.31 × 10 5 UFC 100 mL −1) were obtained in these waters. So, the groundwater is not suitable for human consumption. The most mineralized waters are found in the areas near the Ebrié Lagoon and extend in the direction including the low-income neighbourhoods of Biafra, Nanan Yamousso and Appolo. Pollutant transfer is continuous in the study area and comes from surface sewage, latrines, sewage disposal systems, well water collection materials, and the Ebrié Lagoon. Indeed, the pollutants leave Biafra neighbourhoods where water is heavily polluted and the pollution is amplified by the presence of septic tanks and latrines located on the line of groundwater flow. The main factors influencing water quality are the lagoon water intrusion, the advection mechanism linked to the infiltration of surface water and the lateral migration of pollutants from septic tanks and latrines, and mechanism of dissolution of the clay component of the clayey-sandy layers.
