“…These approaches are useful in finding the complicated relationships among the physicochemical parameters of water resources (Wang et al 2014;Ustaoglu et al 2020). Control of groundwater quality can be done using the water quality index (WQI) which has been widely used by numerous researchers (Sahu & Sikdar 2008;Bhuiyan et al 2016;Sethy et al 2016;Rawat & Singh 2018;Sharmin et al 2020). One of the advantages of WQI is its capability of overall assessment of physicochemical parameters (Abtahi et al 2015).…”

The evaluation of groundwater quality and geochemistry have an important role in the management of water resources in arid and semi-arid regions. In the present study, the spatio-temporal assessment of groundwater quality and hydrogeochemical processes, as well as, statistical analyses in the Azarshahr and Ajabshir planes located in the Urmia Lake basin were investigated. The results revealed that within six years (from 2014 to 2019), the value of total hardness was higher than the permissible level and the quality of groundwater for drinking was very hard and fresh in both planes. In 2019, 84 and 67% of the samples fell within the range of good to poor groundwater quality in the Azarshahr and Ajabshir planes, respectively. The temporal assessment with the help of water quality index values for both planes revealed a good groundwater quality for the Azarshahr plane and a good to poor groundwater quality for the Ajabshir plane. However, deterioration of water quality was observed in both planes from 2014 to 2019. The level of water quality for irrigation was better in the Azarshahr plane than in the Ajabshir plane, due to the presence of fewer salty sites. In addition, Ca–Mg–HCO3 and rock dominance were identified as hydrochemical facies and controlling factor in the groundwater of both planes, respectively. Multivariate statistical analyses indicated both natural and anthropogenic sources (such as weathering, fertilizers, and wastewater) for hydrochemical parameters. It was suggested to develop a comprehensive regulation to control the entry of pollutants into the groundwater of the study area.

“…Bodrud-Doza et al (2020) demonstrated that the children of the western part of the city were more prone to Fe and Mn exposure. According to Sharmin et al (2020), the sublime concentration of Pb and As made 6.4% of groundwater unsuitable for drinking, and the residents who reside in the central-western portion of the city were more vulnerable to carcinogenic risks.…”

“…Although the recent studies focused on the groundwater quality and associated health risks in Dhaka city (Sharmin et al, 2020;Bodrud-Doza et al, 2020), a detailed investigation of supplied tap water quality in relation to dissolved metal(oid)s composition, and evaluation of associated health risks are yet to be done. The consumers of tap water in Dhaka city (~ 95% of total population) are often unsatisfied with the quality of supplied water due to its color and smell, and the levels of the toxic element are poorly known.…”

“…Almost 95% of Dhaka City dwellers depend upon this tap water for their daily household and other seminal purposes, including drinking, bathing, cooking, washing, toilet flushing, construction, and gardening (DWASA, 2019). Also, the supplied tap water is being consumed by lower and lower-middle-income families without any purification (Sharmin et al, 2020). Rising water demand by increasing population causes the annual incremental rate of groundwater extraction (Rahman et al, 2013), which leads to the depletion of groundwater table at least 2-3m per year (Haq, 2006;Hoque et al, 2007;Hossain et al, 2018;Bodrud-Doza et al, 2019a, b).…”

Tap water is the sole source of water in urban cities but gradually being polluted by potentially toxic elements due to unplanned urbanization. The south Asian megacity, Dhaka (capital of Bangladesh) encounters drastic water pollution resulting mainly from anthropogenic differential factors. Consumption of such polluted water distributed to residents by pipelines can trigger health risks. Therefore, this study investigated the public health vulnerability associated with dissolved metal(oid)s in tap water collected across Dhaka city. The concentrations of Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Hg and Pb in measured tap water ranged from 8-156, 7–73, 400-20100, 12–110, 7-101, 12–136, 12–908, 0.03–9.75, 1–5, 0.22–1.30, and 8-118 µg/L, respectively. Among the observed elements, Pb, Cr, and Fe concentrations in 18%, 26%, and 75% of sampling sites, respectively, exceeded the standard guideline criteria of Bangladesh. Entropy-based water quality index demonstrated that ~ 12% of sampling sites possessed water unsuitable for drinking and other household works. The dominant sources of water pollution in this region are industrial effluents and domestic sewage. Both non-carcinogenic and carcinogenic health risks are invoked mostly from ingestion of Co and Pb. Regular consumption of this tap water without further pretreatment may result in detrimental health consequences to both children and adults due to the physiological accumulation of toxic elements over time. This study highlighted a comprehensive scenario of the potentially toxic elements in the tap water of Dhaka city, which will allow policymakers to take adequate measures for sustainable water quality management.
