“…The results of the descriptive analysis of chlorides showed a minimum value, 3.24 mg L -1 , for the reservoir that supplies Camaquã, and a maximum of 16.90 mg L -1 for the groundwater source. Wang et al (2023) reported the Cl − concentration varied from 0.00 to 33.42 mg L -1 , with an average of 1.40 mg L -1 , and was relatively lower than the standard for drinking purposes. The association of chloride with TP indicated the release of domestic e uents.…”

In this research, multivariate statistical analysis was performed to assess the water quality of 4 important drinking water sources in the state of Rio Grande do Sul (RS), Brazil. For this, nineteen water quality parameters (WQP) were applied twice a year, for the period 2013-2018, to assess water quality from different sources. The evaluation was conducted on tree water surface (SWS) and one groundwater source (GWS), separately. Analysis of outliers, Shapiro-Wilk normality test, non-parametric Kruskal-Wallis test, Spearman correlation analysis, hierarchical cluster analysis and the Ward method were carried out to identify the quality of water from different sources. There were higher coefficients of variation for metals, color, turbidity, and total phosphorus. The multivariate analysis pointed out that variables with the highest correlation and grouping in the springs indicate the movement of soil particles into water bodies and their degradation, due to the lack of protection in the areas of these relevant sources of supply.

“…The weighted water quality index (EWQI) surpasses the water quality index (WQI) by incorporating weighted factors, allowing for a more objective and comprehensive evaluation of groundwater quality that considers the relative importance of individual parameters [17]. The human health risk (HHR) model systematically assesses potential health risks linked to exposure to contaminated groundwater, considering factors such as contaminant concentrations, exposure pathways, and toxicity to estimate the likelihood and severity of adverse health effects on individuals exposed to the contaminated groundwater [18].…”

Elucidating the hydrogeochemical processes and quality assessment of groundwater holds significant importance for its sustainable development. In this paper, 53 groundwater samples were collected from a typical agricultural area in the northeastern Chongqing municipality in SW China. The integration of multivariate statistical analysis, ion ratio analysis, geomodelling analysis, the entropy water quality index, health risks assessment, and sensitivity analysis was carried out to explore the hydrochemical processes and quality assessment of groundwater in this study. The statistical results reveal that the cationic concentrations followed the order of Ca2+ > Mg2+ > Na+ > K+, while the anionic components were in the order of HCO3− > SO42− > NO3− > Cl−. Based on the Piper trilinear diagram, the hydrochemical types were shown as Ca-HCO3 and Ca-Mg-HCO3 types. Hierarchical cluster analysis indicated that the groundwater samples could be categorized into three groups. The hydrochemical compositions were primarily influenced by water–rock interactions (e.g., carbonate dissolution and silicate weathering). In terms of irrigation suitability, the sodium adsorption ratios (SARs) ranged from 0.05 to 1.82, and the electrical conductivity (EC) varied from 116 to 1094 μs/cm, indicating that most groundwater samples were suitable for irrigation. The entropy-weighted water quality index ranged from 15 to 94, suggesting that the groundwater samples were suitable for drinking purposes. Non-carcinogenic human health risks followed the order of children > adult females > adult males, within the average values of 0.30, 0.21, and 0.18, respectively. Sensitivity analysis showed that the parameters had the weight order of NO3 > body weight (BW) > ingestion rate (IR) > exposure frequency (EF). Hence, we recommend prioritizing the management of areas with high salinity levels, while avoiding the excessive use of nitrogen fertilizers, raising awareness among local residents about safe groundwater, and providing robust support for the sustainable development of groundwater in typical agricultural areas.
