“…Findings demonstrated that a positive correlation was shown between Cr and Cu in DW samples. Similar findings were observed in water quality studies in Saudi Arabia [62], India [63], Sri Lanka [64], Egypt [65], Burkina Faso [66], Greece [67], Iran [68], and Turkey [69]. Likewise, a positive correlation between Fe and Zn was observed and comparable to the result of the studies by Atangana and Oberholster [70], Esmaeili et al [71], Duggal et al [72], Varghese and Jaya [73], and Karthikeyan et al [74].…”

Clean and safe drinking water is an integral part of daily living and is considered as a basic human need. Hence, this study investigated the suitability of the domestic water (DW) and groundwater (GW) samples with respect to the presence of metals and metalloid (MMs) in San Jose, Occidental Mindoro, Philippines. The MMs analyzed in the area of study for DW and GW were Arsenic (As), Barium (Ba), Copper (Cu), Chromium (Cr), Iron (Fe), Lead (Pb), Manganese (Mn), Nickel (Ni), and Zinc (Zn). The results revealed that Pb has the mean highest concentration for DW, while Fe is in GW resources in the area. Quality evaluation of DW and GW was performed using Metal Pollution Index (MPI), Nemerow’s Pollution Index (NPI), and Ecological Risk Index (ERI). The mean NPI value calculated for DW was 135 times greater than the upper limit of the unpolluted location category. The highest NPI observed was 1080 times higher than the upper limit of the unpolluted site category. That of the ERI observed in the area was 23.8 times higher than the upper limit for a “low” ERI category. Furthermore, the health risk assessment (HRA) of the GW and DW of the study area revealed non-carcinogenic health risks of the MMs analyzed in GW samples, and potential carcinogenic health risks from As, Cr, Pb, and Ni in DW. The use of machine learning geostatistical interpolation (MLGI) mapping to illustrate the PI and health risk (HR) in the area was an efficient and dependable evaluation tool for assessing and identifying probable MMs pollution hotspots. The data, tools, and the process could be utilized in carrying out water assessment, the evaluation leading to a comprehensive water management program in the area and neighboring regions of similar conditions.

“…The deterioration of groundwater quality has attracted the attention pf researchers, as high concentrations of certain elements could potentially cause adverse health effects, including a variety of cancers and noncarcinogenic illnesses like bone and kidney diseases [1]. Due to physical and behavioral differences, various populations would have different sensitivities to the toxic chemical elements contents of groundwater [29].…”

Groundwater chemistry and its potential health risks are as important as water availability in arid and semiarid regions. This study was conducted to determine the contamination and associated health threats to various populations in a semiarid basin of north China. A total of 78 groundwater samples were collected from the shallow unconfined aquifers. The results showed that the phreatic water was slightly alkaline, hard fresh water with ions in the order of Ca2+ > Na++K+ > Mg2+ and HCO3− > SO42− > Cl−. Four hydrochemical elements, NO3−, F−, Mn and Zn, exceeded the permissible limits. NO3− and F− contaminants may pose health risks to local residents, while the risks of Mn and Zn are negligible. Dermal exposure is safe for all populations, while the oral pathway is not. Minors (i.e., infants and children) are susceptible to both NO3− and F− contaminants, and adults only to NO3−. The susceptibility of various populations is in the order of infants > children > adult males > adult females. Anthropogenic activities are responsible for the elevated levels of NO3−, Zn, Total dissolved solids (TDS), while F− and Mn are from geogenic sources. Thus, differential water supplies, strict control of waste, and rational irrigation practices are encouraged in the basin.

“…They account for only 2.5% of the planet's surface water, with a significant portion existing in the form of ice and snow, making it less accessible for human use. 1 In recent decades, the world has witnessed the effects of climate change and declining rainfall, particularly in arid and semi-arid regions like Iraq. 2 Iraq faces a compounded issue as its surface water sources are limited, and the Tigris and Euphrates rivers, along with their tributaries, originate in neighboring countries that control the flow of these rivers.…”

Background: The primary objective of this study was to assess the nitrate ion concentration in drinking water and determine the potential health risks associated with nitrate contamination for humans. Methods: A total of 100 water samples were collected from ten sites, including the Dandan water supply station and adjacent residential neighborhoods on the right side of Mosul city between September 2021 and February 2022. Results: The results of the study revealed that the concentration of nitrate ions ranged between (0.95-3.614 mg/L). Based on the study’s results, all of the analyzed water samples fell within the international drinking water quality standards set by the World Health Organization. The concentrations of nitrate ions corresponded to low values of both chronic daily intake (CDI) and hazard quotient (HQ or QI), which ranged from 0.05162 to 0.18164 mg/kg/day and 0.03226 to 0.11357, respectively. Consequently, the hazard index (HI) for this study remained within safe limits for drinking water. The study also revealed that infants and individuals within the age group of 21 and older were the most susceptible to potential nitrate-related health risks, while the age group of 16 to 18 exhibited the lowest susceptibility to such risks. Conclusion: The study recommends the use of examined water for drinking due to its safe and healthy nitrate ion concentration. It further suggests the continuation of periodic assessments of drinking water supply stations to ensure ongoing consumer safety, as no potential health risks, including cancerous and non-cancerous risks, were identified.
