“…However, samples T-4 (pH ¼ 9.03) and T-6 (pH ¼ 8.53) contained a pH slightly higher than the recommended health-based guideline value (Supplementary Table S1), which is about 5.7% of the total TWWs in the primary schools (Table 1). Recently, Islam et al (2020) reported that the average pH of groundwater in coastal regions was 7.34 and 7.44 during wet and dry seasons, respectively, which are slightly lower than this study. In addition, the pH of groundwater in the Khulna district was reported to be 7.2 (range: 6.5-7.9) (Islam et al 2017), which is a bit lower than this study.…”

“…About 92% (32 out of 35) and 66% (23 out of 35) of groundwater exceeded the safe levels stipulated by WHO and US EPA (0.3 mg L À1 ) and BDWS (0.3-1.0 mg L À1 ), among which sample D-5 indicated the highest content of Fe 8.58 mg L À1 (Table 1). In Bangladesh's coastal region, the average Fe content was reported to be 6.24 + 8.41 and 5.13 + 7.02 mg L À1 during wet and dry seasons, respectively (Islam et al 2020), which are about 2-3 times greater than this study. In addition, a study from Shyamnagar and Assasuni in the Satkhira district reported about two times higher level of Fe content (4.9 + 4.76 and 3.59 + 2.50 mg L À1 , respectively) in groundwater Rakib et al 2020).…”

“…Also, in coastal regions (Khulna, Bagerhat, Satkhira, Patuakhali, etc. ), the average chloride content was reported to be 2,005.74 + 2,685.5 mg L À1 (Islam et al 2020), which is also severalfold higher than this study. This extensive chloride content was considered one of the chlorides' original salinity levels since they are strongly correlated.…”

Scarcity of safe drinking water in the coastal regions throughout the world has long been recognized due to hydrological vulnerability and natural disaster, which is severe in developing countries like Bangladesh. This study focuses on trace metal(loid)s contamination and their associated health risks for primary school children from the consumption of tubewell water at school time in the vulnerable southwest coastal region of Bangladesh. The average content of electrical conductivity (EC), turbidity, chloride, total dissolved solids (TDSs), hardness, iron (Fe), and manganese (Mn) were 1,983.6 ± 1,434.6 μS cm−1, 10.46 ± 10.3 NTU, 676.3 ± 648.1, 1,089.1 ± 788.6, 560.6 ± 326.6, 2.18 ± 1.99, and 0.19 ± 0.36 mg L−1, respectively, which exceeded their respective health-based guideline values. The concentrations of arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn) were lower than the World Health Organization provisional guideline values. Spearman's correlation analysis revealed that the EC of groundwater is dependent on TDS, chlorides, and other cations contributing to hardness, while turbidity results from the Fe content in groundwater. The hazard quotients (HQs) of As, Fe, Mn, and Zn intake were lower than unity for both boys and girls, indicating no non-carcinogenic risks to the children. However, cancer risks (CRs) from As exposure through drinking water were 1.5 and 1.8 times higher than the provisional safe value of 10−4 for boys and girls, indicating a lifetime cancer risk to the school-going children. Therefore, prompt and effective monitoring is a crying need to ensure water's continuous usability for drinking purposes in the study area.

“…The groundwater quality index (GWQI) is a useful tool to establish water quality and indicates the overall impact of chemical composition on the water quality [18,19]. Initially, the water quality index (WQI) was developed by the National Sanitation Foundation as a standard index for water quality assessment and also as a technique of rating water quality [20].…”

Human activities and natural factors determine the hydrogeochemical characteristics of karst groundwaters and their use as drinking water. This study assesses the hydrogeochemical characteristics of 14 karst water sources in the Apuseni Mountains (NW Romania) and their potential use as drinking water sources. As shown by the Durov and by the Piper diagrams, the chemical composition of the waters is typical of karst waters as it is dominated by HCO3− and Ca2+, having a circumneutral to alkaline pH and total dissolved solids ranging between 131 and 1092 mg L−1. The relation between the major ions revealed that dissolution is the main process contributing to the water chemistry. Limestone and dolostone are the main Ca and Mg sources, while halite is the main Na and Cl source. The Gibbs diagram confirmed the rock dominance of the water chemistry. The groundwater quality index (GWQI) showed that the waters are of excellent quality, except for two waters that displayed medium and good quality status. The quality of the studied karst waters is influenced by the geological characteristics, mainly by the water–rock interaction and, to a more limited extent, by anthropogenic activities. The investigated karst waters could be exploited as drinking water resources in the study area. The results of the present study highlight the importance of karst waters in the context of good-quality water shortage but also the vulnerability of this resource to anthropogenic influences.
