The aim of the article was the analysis of the physicochemical quality of water within the hydropower plant on the Ślęza River in Wrocław (south-west Poland) in the context of the European Union's classification of water quality, as well as an assessment of the potential impact of hydropower plants on this quality. The study uses the results of monthly tests from three measurement points within the hydropower plant on the Ślęza River in the city of Wrocław (points upstream and downstream the hydropower plant and the reference point), from the period June 2018 to May 2020. The analyses covered 10 physicochemical parameters, i.e.: pH, electrical conductivity (EC), water temperature, turbidity, NH4-N, NO3-N, NO2-N, total phosphorus, dissolved oxygen and BOD5. The conducted analysis showed that the hydropower plant has no clear influence on the physicochemical quality of the water in the Ślęza River, other interactions present in the catchment area are more important. From the effects visible in the results, a decrease in the amplitudes of water temperature downstream the hydropower plant compared to the other points was noted, as well as a lower median of its value (statistically significant changes). An additional noticeable effect was the increase in water oxygenation below the damming, but it was not statistically significant. It has been shown that the physicochemical condition of water at the tested points does not meet the assumed standards for 8 out of 9 parameters (except for water temperature). The largest exceedances of the limit values concerned NO2-N (up to 923% of the norm), and the most consistent, almost constantly occurring – EC (23 out of 24 months). The reason for the high NO2-N content was most probably surface runoff from the fields and the re-suspension of sediments rich in nutrients, while in the case of EC, its high values result from the specificity of the catchment area.

Water resources are threatened nowadays by pollution that comes from domestic, industrial and agricultural discharges without prior treatment. This pollution causes the degradation of water quality. Surface pollutants can seep through the soil into water tables. The objective of our work is to assess and control the physicochemical quality of the Chari Baguirmi groundwater, to protect human health. The quality of 83 boreholes was assessed, while performing analysis for 12 physicochemical parameters at the National Water Laboratory and at the Center for Quality Control of Foodstuffs in Chad. These parameters are pH, EC, Ca2+, Mg2+, Na+, K+, Cl−, SO42−, NH4+ and NO3−, Fe2+ and HCO3−. The results obtained were also compared with WHO standards. The geochemical statistical approach has made it possible to characterize hydro geochemical properties and to understand the major processes of mineralization of groundwater resources in the Chari Baguirmi region in Chad. Some of its waters are acidic and weakly mineralized, rich in Fe2+ and NH4+. The origin of the mineralization is due to the alteration of the host rocks and to the hydrolysis of silicate and ferromagnesian minerals, as well as anthropogenic pollution. The ammonium concentrations in N’Djamena boreholes are higher than WHO standards, indicating the presence of pollution which may come from organic waste. These results constitute a preliminary step in understanding hydro geochemical functioning and a basis for monitoring the physicochemical quality of water in the study area.

In Senegal, the majority of the regions are not served by the drinking water supply networks. The phenomenon is more pronounced in rural areas, particularly in Sinthiou Maléme commune. For example, communities living in these areas often use well water and borehole. This work has been undertaken to evaluate the physicochemical quality of the water resources consumed by these populations. A total of 24 water samples were taken from the single borehole and 02 publics wells, let be 8 samples per source of water. To assess the quality of these different sources, the physical parameters (electrical conductivity, pH, total dissolved solids and hardness) and chemical parameters (F-, SO42-, PO43-, Fe and NO2-) were analyzed by the photometric method. The results obtained show that, from the physical point of view, drilling water is highly mineralized, slightly hard and has a basic tendency, unlike wells. Chemical analysis shows that well waters are heavily loaded with phosphate ions and nitrites. Based on the parameters analyzed, the quality of the drilling water is chemically acceptable. Studies on the elements of metallic traces will be envisaged to better assess the quality of this drinking water. Au Sénégal, la majeure partie des régions n’est pas desservie par les réseaux d'adduction d’eau potable. Le phénomène est plus accentué en milieu rural notamment dans la commune de Sinthiou Maléme. Ainsi, les communautés qui vivent dans ces zones ont souvent recours à l'eau des puits et des forages. Ce présent travail a été entrepris en vue d’évaluer la qualité physico-chimique des ressources en eaux consommées par ces populations. Au total 24 échantillons d’eaux ont été prélevés de l’unique forage et de 02 puits publics, soit 8 prélèvements par sources d’eaux. Pour apprécier la qualité de ces différentes sources, les paramètres physiques (conductivité électrique, pH, totale des solides dissous et dureté) et chimiques (F-, SO42-, PO43-, Fe and NO2-) ont été analysés par la méthode photométrique. Les résultats obtenus montrent que, du point de vue physique, les eaux de forage sont fortement minéralisées, légèrement dures et présentent une tendance basique contrairement à celles des puits. L’analyse chimique montre que les eaux de puits sont fortement chargées en ions phosphates et nitrites. Sur la base des paramètres analysés, la qualité des eaux de forage est chimiquement acceptable. Des études sur les éléments des traces métalliques seront envisagées pour mieux apprécier la qualité de ces eaux de consommation.
