    Opis:
    Selected quality parameters of groundwater from four artesian wells of the Jurassic aquifer located in the center of Krakow (Cracow) are presented. Water from these public wells i.e. Nadzieja, Jagielloński, Królewski and Lajkonik, during 20 years of exploitation, has had constant bacteriological purity and rather constant chemical composition. A comparison of nitrates concentration in the investigated wells with Quaternary wells located in the same area, and with municipal drinking water in Krakow shows that water from the above-mentioned four wells is characterized by the lowest concentration of NO3 ions. Very low nitrate and nitrite concentration suggests that despite passage of time the chemical composition of water from the investigated intakes is not affected by anthropogenic pollution because of isolation of water reservoir due to geological conditions.

    Soummam Valley
    Opis:
    Analysis of groundwater quality in the alluvial aquifer of the lower Soummam Valley, North-East of Algeria, was realised through the application of multivariate statistical methods: hierarchical cluster analysis (HCA) in Q and R modes, factorial correspondence analysis (FCA), and principal component analysis (PCA), to hydrochemical data from 51 groundwater samples, collected from 17 boreholes during periods of June, September 2016 and March 2017. The objectives of this approach are to characterise the water quality and to know the factors which govern its evolution by processes controlling its chemical composition. The Piper diagram shows two hydrochemical facies: calcium chloride and sodium bicarbonate. Statistical techniques HCA, PCA, and FCA reveal two groups of waters: the first (EC, Ca2+, Mg2+, Cl-, SO42- and NO3-) of evaporitic origin linked to the dissolution processes of limestone rocks, leaching of saliferous soils and anthropogenic processes, namely contamination wastewater and agricultural activity, as well marine intrusion; and the second group (Na+, K+, and HCO3-) of carbonated origin influenced by the dissolution of carbonate formations and the exchange of bases. The hermodynamic study has shown that all groundwater is undersaturated with respect to evaporitic minerals. On the other hand, it is supersaturated with respect to carbonate minerals, except for water from boreholes F9, F14, and F16, which possibly comes down to the lack of dissolution and arrival of these minerals. The results of this study clearly demonstrate the utility of multivariate statistical methods in the analysis of groundwater quality.

    classification of soil and groundwater quality
    Opis:
    The result of human activity is polluting the soil and water. Based on the results of heavy metals studies it can be stated that the level of contamination of soil and water in urban areas is not high. This image is changing after taking into account other types of pollution. Besides some heavy metal contamination urban areas are contaminated with petroleum. Contamination of oil derivatives has a significant impact on the soil and water environment. In addition, some petroleum substances, such as petrol, have high vapour pressure. This causes a displacement of soil air from the vadose zone through the hydrocarbon gases, which creates a risk of explosion, especially in urban areas. This paper describes the pollution of ground-water oil derivatives in an urban area on the example of an oil filling station, operated for several years. In order to assess the condition of soil, 90 soil samples from different depths and 20 samples of groundwater were taken. Samples were taken for laboratory oil content tests. Using a computer program, a map of quality standards exceedances of soil and groundwater at the oil filling station and its vicinity was created. Results of laboratory tests of water samples are presented in tables and based on them, the classification of the underground water quality was made. Results of this study indicate a significant pollution of soil and groundwater exceeding the applicable standards. Condition of the soil and the quality of underground water in the oil filling station indicate the necessity of reparation.

    Opis:
    The aim of the study was to evaluate the impact of the landfill on the groundwater environment. The assessment of water status in the region of landfill sealed with a layer of clay with a thickness of 0.5 m, was based on the own research and monitoring received from the municipal office, and conducted in 2007–2010. Waters flowing out of the landfill revealed an increase in pollution indicators such as: total organic carbon (TOC), concentrations of PAHs and heavy metals including zinc, cadmium, and chromium. It was demonstrated that the landfill sealed with a clay layer does not reduce the outflow of leachate to groundwater, but also that the purity of these waters is influenced by increased agricultural activity in the areas adjacent to the landfill.

    Opis:
    With a flow estimated at 1200 m3∙s–1 and a height of 8 m downstream, the flood that occurred on October 10, 2008 spread along the M’zab River over a length of more than 180 km. Material and human damage is visible, but its effects on the quality of the waters of the alluvial layer remain unknown: this is the purpose of this paper. Samples of groundwater were taken during the period 2005–2012 in 4 oases of the valley. Physicochemical analyses were performed using molecular and flame spectroscopic methods and also volumetric methods on water samples. The results obtained were interpreted using histograms and hydrochemical diagrams, such as the Avignon software (L.H.A) (version 4, 2008). Low effect of flood on the water quality of the alluvial aquifer was manifested by concentrations of magnesium sulphate and calcium chloride. On the other hand, there is an accumulation of salts infiltrated by sewage except for the zone of Bouchen. The diagrams show that there is an improvement in water quality in this area.
    Osiągając przepływ szacowany na 1200 m3∙s–1 i wysokość fali 8 m, powódź, która wystąpiła 10 października 2008 r., objęła swoim zasięgiem 180 km biegu rzeki M’zab. Straty ludzkie i materialne są znane, ale wpływ powodzi na jakość wody poziomów aluwialnych pozostaje nierozpoznany i dlatego stał się celem niniejszych badań. Próbki wód gruntowych pobierano w latach 2005–2012 w czterech oazach w dolinie rzeki. Próbki zostały poddane analizom fizycznym i chemicznym. Otrzymane wyniki interpretowano z wykorzystaniem histogramów i diagramów hydrochemicznych opracowanych za pomocą oprogramowania Avignon (L.H.A), wersja 4, 2008. Stężenie siarczanu magnezu i chlorku wapnia dowodziło niewielkiego wpływu powodzi na jakość wód aluwialnych poziomów wodonośnych. Z wyjątkiem strefy Bouchen, stwierdzono jednak akumulację soli infiltrujących ze ściekami. Na podstawie wyników badań można zaobserwować poprawę jakości wody na badanym obszarze.
