“…Cu concentrations were below the guideline values established by the WHO and by the Directive 98/83/EC [26,27] and no significant spatial variation among sites was noticed. The concentration of Ni was influenced by the soil type, pH level and aquifer depth [50]. In this study, almost all waters had Ni concentrations much lower than the guideline value established by the WHO for drinking water purposes, except for GWR23 and GWR24, which had Ni concentrations close to the guideline established by the Directive 98/83/EC [27].…”

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.

“…Lead exposure may cause cancer, vitamin D deficiency, high blood pressure, brain damage, infertility, and mental impairment in children [30]. An erythropoietin effect, such as a swollen goiter, can be induced by excessive chromium ions in water [31]. Water with high levels of iron can cause fatigue, heart and liver disease, and diabetes mellitus [32].…”

The increasing prevalence of water-borne diseases necessitates periodic monitoring of domestic and drinking water sources. The current study assessed the safety of well water in the four emirate zones (Gwandu, Yauri, Argungu, and Zuru) of Kebbi State, Nigeria. Using normal procedures, samples of well water were examined for heavy metals, physicochemical characteristics, and microorganisms, and the results were compared to the World Health Organization (WHO) drinking water criteria. The heavy metals' chronic daily ingestion (CDI) and hazard quotient (HQ) were also determined. The results showed that well water in the four emirate zones had normal temperature, biochemical oxygen demand (BOD), dissolved oxygen (DO), total suspended solids (TSS), and zinc (Zn). However, non-permissible concentrations of lead (Pb), iron (Fe), cadmium (Cd), chromium (Cr), and pH (Gwandu and Argungu only) were detected in all the water samples. Except for Cd and Cr in children, the CDI and HQ of the heavy metals were normal. The microbiological examinations revealed that the water samples from the four zones had abnormal levels of Bacillus species (bacteria), Escherichia coli (bacteria), Staphylococcus aureus (bacteria), Aspergillus niger (fungi), Mucor racemosa (fungi), and Paecilomyces variotti (fungi). The results obtained suggest that well water in the four zones is not suitable for human consumption unless treated.

“…All of the aforementioned factors have the potential to cause significant pollution, which is harmful to human health (Alqahtani, et al, 2020). However, certain of these metals, such as zinc and iron, are required for living creatures' growth and development, but others, such as cadmium, mercury, and lead, are considered non-essential owing to their toxicity (Adeyemi et al, 2021). Understanding the origins, fate, and possible health hazards of heavy metals necessitates determining the heavy metal concentration of groundwater (Zang et al, 2018).…”

The current study looked at how heavy metals are distributed in groundwater and how they affect people's health during the pre-monsoon, monsoon, and post-monsoon seasons, water samples were collected from hand-dug wells and boreholes in the Malvan coastline and surrounding areas of Sindhudurg, MS, India's bordering the Arabian Sea. A total of 42 samples were collected and analyzed using standard methods for elements such as Iron (Fe), Zinc (Zn), Manganese (Mn), Copper (Cu), Fluoride (F), and Chromium (Cr). The data were analyzed using descriptive and inferential statistics. In the study area sampling location, the seasonal mean concentrations of heavy metals in groundwater samples (3 seasons) for Fe, Zn, Mn, Cu, Cr, and F were 1.39, 0.166, 1.148, 0.046, 0.008, and 0.509 mg/L, respectively. The metals were found in groundwater in the following order: Fe > Mn > F > Zn > Cu > Cr. The total Hazard Index (HI) of the metals in the groundwater samples revealed a high danger for people of all ages. In general, a high HI score (HI > 1.0) indicates negative non-cancer effects, with babies being the most vulnerable. For the studied metals, the cumulative cancer risk in the study areas is extremely low. The calculated health risk index indicates that Cr is high and the cancer risk on three categories such as Child, Adult and Infant is possible. Keywords: Seasonal assessment, Trace Elements, Groundwater contamination, human health risk, Malvan coastal area.
