“…Factor one loadings which account for 25.76% of variability (Table 2) is largely related to mineralization [19] and indicates that the EC and TDS in the study area are mainly due to Na + and SO4 2with Ca 2+ playing a substantial role and related to the occurrences of Cd 2+ , Cr 2+ and Pb 2+ . Factor two which accounts for 19.26% of observed may be associated to weathering of silicates and K-feldspar [11,19,20]. Gibbs plot [21] showed water-rock interaction as main influence on groundwater chemistry (Fig.…”

This study was aimed at understanding the factors affecting groundwater for the benefit of water resources management. Groundwater collected from 18 sites over an area of 770 Km2 was analysed. Temperature (Temp.), pH, Total Dissolved Solids (TDS) and Electrical Conductivity (EC) were measured in the field and 15 chemical parameters analysed in the laboratory. Factor Analysis (FA) of physiochemical results indicated mineralization, weathering of silicates and K-feldspar, and anthropogenic sources were mainly responsible for groundwater chemistry. Hierarchical Cluster Analysis (HCA) revealed sample clusters were mainly controlled by structure rather than by lithology, water source or altitude because 86% of cluster I samples occurred along a NNE-SSW trending fault zone. It was thus concluded that water-rock interaction, tectonics and anthropogenic factors are responsible for water physiochemistry.

The result of this operation are high factor loadings obtained for the variable correlated in the factor and low factor loadings obtained for remaining variable [36,38,39].

“…To delineate the spatial distribution of water quality based on the potential for NO 3 pollution, we employed a hierarchical cluster analysis (HCA) [36,37] to identify groups with similar major ion compositions and field parameters. Based on Gibbs' [41] plots (Figure 4), water-rock interactions appeared to be the major mechanism controlling the hydrochemistry of water in UB for shallow alluvial aquifer and bedrock aquifer groundwater, as well as river water.…”

Ulaanbaatar (UB), the capital of Mongolia, is one of the fastest-growing cities in the developing world. Due to increasing demand driven by rapid population and industrial growth, sustainable water resource management is required. Therefore, we investigated sustainability in UB from the perspective of water quality. During five sampling campaigns, we collected 135 water samples (58 from bedrock wells, 44 from shallow wells tapped into the alluvial aquifer, 24 from rivers, and 9 from springs). The hydrochemistry of the water samples was controlled by two major processes: NO 3 contamination, and silicate and carbonate mineral weathering. The groundwater samples could be classified into three groups based on their NO 3 levels and spatial distribution. Group 1 had natural background NO 3 levels (median: 1.7 mg/L) and silicate weathering-dominant water-rock interactions and was distributed in the alluvial aquifer along the floodplain. Group 2 was dominated by carbonate weathering processes, had a maximum NO 3 concentration of 47.4 mg/L, and was distributed between the riverbank and upslope area; overall, it reflected ongoing contamination. Group 3 was distributed in the upslope Ger districts and showed significant NO 3 contamination (range: 64.0-305.4 mg/L) due to dense and poor living conditions. The stable isotope signatures indicated that the city's major water supply from riverbank filtration (i.e., Group 1 wells) mixed dynamically with the river; therefore, it showed no sign of NO 3 contamination. However, the isotope values and bedrock groundwater quality of wells in Groups 2 and 3 implied that they were closely connected, with the same water source, and showed a strong potential for expanding NO 3 contamination toward Group 1 wells. To support sustainable development in UB, the implementation of appropriate institutional measures to protect and preserve water resources, with systematic spatio-temporal monitoring and a focus on Ger districts, is crucial.

“…The consumption of groundwater from private wells in households is increasing significantly, due to the lower cost of maintaining the wells than the water supplied by the waterworks. However, this water is usually untreated, which makes it a carrier of diseases [7][8][9]. In uncontaminated water systems, the main ions are released through rock weathering and water quality is related to factors such as the composition of precipitation, geological structure, mineralogy of aquifers, geological processes within the aquifer and waterrock interactions [8,10].…”

Funds collection zebranie funduszy Summary Background. The use of groundwater from private wells in households is increasing significantly. However, this water is usually untreated, making it a carrier of diseases. Chemical composition plays a key role in assessing groundwater quality. Due to rapid urbanization and industrialization of the environment, pollutants (especially toxic elements) are constantly being released into the aquatic environment and pose a threat to human and animal health. There is a large variety of microorganisms in aquifers. The use of groundwater from aquifers as sources of drinking water without water treatment or disinfection is a public health problem. Material and methods. The material for the study consisted of water samples taken from used and unused domestic wells in villages located in Lubelskie Province, Biała Podlaska County, Janów Podlaski municipality, Poland. ICP-OES was used to determine the composition of elements. The total number of mesophilic and psychrophilic bacteria was determined for 5 wells using the pour-plate method according to the Polish Standard PN-EN ISO 6222:2004. Results. The water from the wells is unfit for consumption due to high microbiological contamination. A study would have to be carried out on the content of specific pathogenic microorganisms. In most of the samples analyzed, the heavy metal content of the water is below admissible limits. Conclusions. Water resources of the highest quality should be increasingly protected and retained as drinking water reserves. This is extremely important in view of the progressing climate change and the slow process of groundwater renewal.
