abstract = {This comprehensive risk assessment, done for a MAR facility in Tarnów, southern Poland, covers two MAR techniques: infiltration ditches and induced bank filtration during the operation and planned potential expansion phases. Two methods were applied: the semi-quantitative risk assessment matrix and the probabilistic risk assessment – fault tree analysis (PRA-FTA), and their advantages and limitations analysed. Both methods examine a range of technical and non-technical risks that may pose a threat to the efficient functioning of the MAR facility in Tarnów, which supplies about 25% of the city's population with drinking water. It was found that 34 of the 65 risks analysed could pose a low to high risk for the Świerczków well field. The predominant risks potentially reducing MAR efficiency or leading to MAR failure are technical ones. According to the PRA-FTA method, if no preventive measures are taken, there is a 99.5 and 99.3% probability of the MAR system failing during the operational and expansion phases, respectively. The results indicate that the most serious risk is associated with the insufficient initial removal from the recharge river water of suspended solids, which clog infiltration ditches. The risks scored as medium relate to the threat of groundwater inflow from an extensive industrial zone, lying to the east of the well field, and to climate change negatively affecting the quantity of groundwater resources. This is the first example in Poland of a risk assessment for an existing MAR facility and its expansion, based on a broad spectrum of technical and non-technical risks present at the Świerczków well field, using two methods: the risk assessment matrix and PRA-FTA. This case study is a practical example of how to perform a risk analysis for a MAR site. It can make an important contribution to existing knowledge in this field and enrich the subject literature, a particularly relevant aspect given the widespread use of MAR techniques in Central Europe for the supply of drinking water to the public. © 2023 Elsevier B.V.},

abstract = {The article presents the impact of Zn and Pb ore mining and land use on ecohydrological changes in the area of the Biała Przemsza valley in the historical aspect, with particular emphasis on the period 1941–2021. GIS was used to analyse the maps to identify spatial and temporal changes in land use. The following trends could be observed in the spatial development of the Biała Przemsza valley: rapid urbanisation and industrialisation in the 21st century, marked reduction in the surface area of arable land and sands, and dynamics of the increase in the surface area occupied by forests. Notable changes occurred in the plant ecosystems between 1941 and 2021 due to land management. Groundwater level lowering due to mining activity resulted in the change from wet meadows to fresh or dry xerothermic grasslands, while forest cover increased by 4% within the catchment area. The hydrographic network evolved. After the commissioning of the Zn-Pb ore mines Olkusz and Pomorzany in the 1960s and 1970s, a regional depression cone with an area of 400 km2 was formed, while the maximum groundwater inflows to the mines reached 360 m3/min. Changes in the hydrodynamic conditions have resulted in changes in the hydrogeochemical regime of the Triassic aquifer manifested by increased levels of, e.g., SO4 and Cl. Wastewater with lignosulphonate compounds from the paper factory caused periodic degradation of some of the water flowing into the Pomorzany mine. As a result of mining activity, the character of some sections of the Biała Przemsza river changed to an infiltrating one, the quantitative depletion of groundwater resources within the range of the mine drainage cone occurred, river springs disappeared, and the flow in the river decreased. At the same time, mine water was discharged to the tributaries of the Biała Przemsza. A radical reduction in the flow of the Biała Przemsza and its tributaries occurred after the decommissioning of the Zn-Pb ore mines at the turn of 2021 and 2022. © 2023 by the authors.},

abstract = {The diversity of groundwater chemistry in the Peshkopi gypsum karst area may be related to its setting within the tectonically active Korab Massif (Albania), as shown by field tests of temperature, pH, Eh and EC, and sampling of the waters for chemical analysis (both major and trace components) from cool brackish springs and mineralized thermal springs. The relationship between the chemical composition of the spring waters and of the reservoir rocks was elucidated by analysis of anhydrite-gypsum rocks and experimental dissolution of an anhydrite-gypsum sample. Statistical analysis was used in the processing of hydrochemical data. Comparison of analytical results from 2019 with earlier data indicates compositional stability of the groundwaters over time. Our results together with statistical analysis of the hydrochemical data support an earlier hypothesis of two systems of groundwater circulation within the anhydrite-gypsum deposits of the Peshkopi region. A shallow circulation system involves cold (10–14°C), mainly brackish SO4-Ca waters with very low concentrations of Na+ and Cl-ions, reflecting their formation in a sulphate rock environment that probably corresponds spatially with a gypsum layer formed by hydration of anhydrite in the near-surface zone. A deep circulation system conditioned, inter alia, by the presence of a large fault, brings to the surface water at up to 44°C, saturated with H2S, mineralized, of the SO4-Ca type with an increased content of Na, K, HCO3, Cl, BO3 and SiO2. The chemical composition of these waters, regardless of the presence of large amounts of sulphates, is significantly different and suggests the influence of other factors on their formation, such as slow circulation, contact with flysch rocks in the fault zone and the mixing of deep and near-surface waters in the final part of their ascent to the surface. © 2023, Polish Geological Institute.

abstract = {The issue of pharmaceuticals and personal care products (PPCPs) in the water environment has gained increasing interest worldwide. To determine the nature and extent of this problem for Poland, this paper presents a review of research on the presence of PPCPs in Poland, looking at results for different water samples, including wastewater (before and after treatment), landfill leachate, surface water (standing water bodies and rivers), seawater, groundwater and drinking water. The review is based on over 50 scientific articles and dissertations referring to studies of PPCPs. It also briefly outlines possible sources and the fate of PPCPs in the aquatic environment. The review of Polish research has revealed that studies have previously covered at least 39 PPCP groups (270 compounds in total). These studies focused mainly on wastewater and rivers, and only a few concerned landfill leachate and seawater. They most often reported on nonsteroidal anti-inflammatory drugs and antibiotics. The highest concentrations of the analysed PPCPs were found mainly in raw wastewater (e.g.; naproxen; up to 551;960 ng/L), but they were also occasionally found in surface water (e.g.; azithromycin; erythromycin; irbesartan and metoprolol) and in groundwater (e.g.; N;N-diethyl-meta-toluamide; known as DEET; up to 17;280 ng/L). Extremely high concentrations of bisphenol A (up to 2;202;000 ng/L) and diclofenac (up to 108;340 ng/L) were found in landfill leachate. Although numerous substances have been detected, PPCPs are still not monitored regularly, which makes it difficult to obtain a clear understanding of their incidence in the water environment. © 2021 by the authors.

abstract = {The functioning of Uzbekistan’s economy is closely linked to the water resources of its huge cross-border rivers: the Amu Darya and the Syr Darya, as well as to the groundwater present within their basins. Both natural lakes and artificial reservoirs (e.g. the Aydar-Arnasay system of lakes; the Kayrakkum Reservoir; the Chardarya Reservoir) are present there, which retain significant amounts of water, and large canals with lengths of up to several hundred kilometres which involve complex hydraulic structures are used for irrigation purposes. All these are components of a water management system which needs optimisation; as much as 80% of agricultural land is irrigated, with 70% of the water being lost due to inefficient irrigation systems. The consequence of this allocation of river flows and the overuse of water in irrigation systems has been the disappearance of the Aral Sea (1960 year – 68;900 km2; 2017 year – 8;600 km2) and the inflow of water into the Sarygamysh Lake as well as the reduction of Uzbekistan’s groundwater resources by about 40%. The intensive development of irrigated agriculture is associated with changes in surface and groundwater quality caused, inter alia, by the increased use of chemicals in agriculture and the discharge of collector-drainage waters into river systems as well as their reuse. The extent of environmental degradation in some areas (especially in the Aral Sea region) is unique on a global scale. The origins of Uzbekistan’s other hydrological tourist attractions are related to attempts to ensure the availability of water for both human consumption and industrial use under conditions of water scarcity in the country’s arid and semi-arid climates. Not just the spectacular watercourses and water bodies present there (e.g. rivers; lakes; canals), but also small water retention facilities and minor infrastructure elements (e.g. wells; springs and retention basins; canals; ditches and flow control structures) are of potential tourist importance. © 2021, ASERS Publishing House.

A comprehensive analysis was carried out concerning spatial development, mining activity, hydrogeological conditions and the biotic environment. The current state of the hydrogeological conditions was also characterized. Mining activity in the vicinity of the studied town caused significant changes in its relief, which contributed to its area dropping by about 5 m. In fact, these terrain forms are overgrown by various forms of vegetation that colonized these areas both naturally and as a result of forest reclamation. The contemporary vegetation of Wojkowice differs from the potential natural vegetation, which is an indicator of the complete anthropogenization of the natural environment. Over 100 years of industrial activity in Wojkowice has also contributed to a strong transformation of the groundwater. There has been a quantitative depletion of usable groundwater in the Triassic and Carboniferous formations. With inflows to the ore mines of up to 17 m3/min, the groundwater table has dropped by more than 60 m. The aquifer of Muschelkalk has been practically drained. At present, wells extract the waters from the Röth aquifer. There has been a major transformation of groundwater chemistry. The waters of the Triassic carbonate complex are anthropogenically transformated and are characterized by increased mineralization, multi-ionic types and usually with a quality class III and IV, and, therefore, they require some treatment. © 2021 by the authors.

abstract = {The Zoloushka Cave, with passages >90 km long and a volume of ~0.65 million m3, is among the largest gypsum caves in the world. The cave was opened in the course of gypsum excavation in a quarry in the village of Criva (Moldova) located just near the border with Ukraine. During the quarry exploitation, with the accompanying pumping of water, the groundwater table was lowered to the bottom part of the gypsum layer. As a result of the pumping, the karst aquifer within the cave labyrinth was fragmented into separate underground reservoirs controlled by the morphology of the karst system and its content of clay deposits. Currently, there are several dozen lakes in the cave with a varied hydrodynamic regime (relict lakes; lakes with direct and indirect hydraulic connection with the aquifer). Research was carried out in February 2020 to determine the degree of, and reasons for, the hydrogeochemical diversity of 10 selected lakes of various hydrodynamic types present in the cave. The degree of variability of the hydrogeochemical parameters of these lakes was found to depend on a number of factors, mainly: The hydrodynamic type of the cave lake resulting from the degree of its hydraulic connection with the aquifer; the geochemical environment of the lake; and anthropogenic influence. The autonomizing role of these factors is the modification (within individual lakes) of the hydrogeochemical context of the transit waters flowing through the cave system to the quarry. © 2021 Korean Mathematical Society.},

The study of the causes and consequences of land-use and other human induced changes was examined by the estimation of biodiversity and environmental requirements of individual species. The studied biotic variables in spring habitats referred to diatoms (algae), mosses, vascular flora and benthic fauna. The species presence was controlled by both natural and anthropogenic factors. The results showed that the heterogeneity of diatoms, mosses and vascular flora of springs are mainly constrained by physical and chemical water parameters. Among other factors reflecting species requirements (including benthic fauna) in the springs were the mineralogical diversification of bottom sediment, discharge and flow velocity, physical and chemical water parameters and anthropopressure. The most natural springs were large outflows Centuria and Błękitne Źrodła. The springs Pióro and Łączki Kobylańskie are among the most anthropogenically modified springs. Various taxa such as postglacial relict Crenobia alpina were found in selected springs (Pilica-Piaski and Centuria). Tracking changes in springs using hydrogeological monitoring and analysis of related bioindicators is the only valuable method for testing long-term trends in our environment. © 2020},

A comprehensive ecological analysis was carried out concerning spatial development, mining activity, hydrogeological and hydrological conditions as well as the biotic environment. Among the unfavourable changes found were a drastic reduction in the agricultural function of the area (from 7.03 to 0.47 km2), mainly due to periodic activity of sand mine in 1967-2002, covering an area of about 5.80 km2, the destruction of the original biocenoses, the depletion and deterioration in quality of the groundwater resources, and man-made transformations of the hydrographic network (during the mine's activity its length reached over 103 km). Vegetation changes during the 70-year period examined were closely related to human mining activity. The greatest changes occurred at the end of the 1960s when large areas of pine forest were cut down. The analysis of vegetation in the former workings demonstrated that the diversity of habitats within the workings results in a significant increase in species (367 plant species; 2002 birds) and community diversity (Molinion caeruleae; Molinion caeruleae; three Natura habitats) there compared to the adjacent areas. On the other hand, favourable changes included the construction of a flood control reservoir, with an area of 560 ha and a volume of 51 million m3, created in 2003-2005, making the area more attractive for tourism and recreation, and an increase in biodiversity, including the establishment of a Natura 2000 site. © 2020 by the authors.},

abstract = {The paper presents the varied presence of nitrates and phosphates in water from caves located in Częstochowa and Kraków, in urban, strongly anthropogenic conditions, representing the vadose zone of the fissure-karstic-porous massif of Upper Jurassic limestones. Hydrochemical research was carried out by the authors in the Cave on the Stone in Częstochowa in 2012–2015, in caves of the Zakrzówek horst from 1996 to 2002, and in the Dragon’s Cave by the research team of J. Motyka in 1995–1998. A number of NO3 and PO4 measurements were performed in waters sampled at these research sites: 20 measurements each of NO3 and PO4 at the Cave on the Stone, 228 of NO3 and 422 of PO4 at Zakrzówek, and 19 each of NO3 and PO4 at the Dragon’s Cave. To assess the quality aspect of N and P compounds in waters from the Cave on the Stone, the results of geochemical modelling were processed using PHREEQC software. In cave waters, the oxidised form of nitrogen NO3 − predominates; in surface waters in the vicinity, unoxidised forms prevail: NH4+, NH3, and NH4SO4 −. Among phosphorus speciations, dissolved forms are dominant: HPO4 2−, H2PO4 −, and the insoluble form CaHPO4; in surface waters, these forms are practically absent. Transformations of water chemistry in ‘urban’ caves, often centuries old, manifest themselves in, inter alia, the occurrence of multi-ionic waters, including seasonal variations and extremely diversified concentrations, with very high concentrations in subpopulations of NO3 (0.2–485 mg dm−3) and P (0.02–6.87 mg dm−3). The common presence of NO3 in waters of the phreatic zone of the Częstochowa Upland, an area developed in an agricultural direction, is documented by, inter alia, the exploitation of intakes supplying the city of Częstochowa (10–57 mg dm−3, 2011) and crenological studies from 2008 to 2015 (NO3, 2–58 mg dm−3), at simultaneously low phosphate concentrations (PO4, 0.02–0.24 mg dm−3). © 2017, The Author(s).},

abstract = {The carbonate fissure–karstic aquifer of Upper Jurassic age is the main aquifer in the Cracow Upper Jurassic Region (CUJR). The aquifer is recharged directly or indirectly by Quaternary or Quaternary–Cretaceous overburden of varying permeability, which predominates diffused recharge. Concentrated recharge occurs locally and has a diverse nature. Field studies carried out in 20 quarries show moderate permeability of the unsaturated zone of carbonate massif. Karst funnels are filled with rubble and clay material and dominate filled fissures with an opening b < 10 mm. The average surface fissure porosity of massive with chalky limestones and bedded limestones reach 0.12 and 0.45 %, respectively, while fissure permeability coefficient is, respectively, kS 6.60 × 10−5 and 1.27 × 10−3 m/s. The average karstification in quarries was determined as nk = 2.5 %. Tracer studies, carried out in an unconfined carbonate Zakrzówek horst in Cracow (Kraków), document vertical migration of infiltrating water through the systems with different hydraulic resistance, with a flow rate from 8.1 × 10−6 to 4.9 × 10−5 m/s and the lateral migration velocity between communicated caves from 6.94 × 10−6 to 1.06 × 10−4 m/s. The significant presence of poorly permeable overburden and moderate fissuring and karstification of rock in the unsaturated zone of CUJR are reflected in the assessment of the Upper Jurassic aquifer vulnerability to contamination, performed by a modified DRASTIC method. In the area of unconfined karst, occupying 55 % of the area, vulnerability to contamination is high, while as much as 45 % of the area is characterized by medium and low vulnerability. © 2016, The Author(s).},

abstract = {Migration and concentration of heavy metals in infiltration waters within unsaturated and saturated zones of a carbonate massif result from their mobility as well as anthropopression. The purpose of this project, carried out in 1995-2005, was to observe changes in the chemical composition of infiltration waters, especially Sr, Ba, Fe, Mn, and Zn concentration in precipitations, in soils and in caves within an unsaturated zone and a saturated zone situated in a carbonate massif. Field research was conducted in the Prądnik River’s drainage basin and at the Zakrzówek horst in Kraków. The chemical and mineralogical composition of limestone samples from 11 different quarries and natural exposures in the Kraków Upland were studied. The mineralogical research was conducted using the Roentgen diffraction method. The concentration of Sr, Ba, Fe, Mn and Zn in 700 samples from precipitation, caves and saturated zone waters was analysed. The determinations were made using mainly the ICP-AES Plasma 40 and ICP-MS Elan method. To assess the quality aspects of the migration of heavy metals, the results of the geochemical modelling were accounted for using the PHREEQC software. The hydrochemical research has shown distinct variability of concentrations of the analysed minor elements in different forms of precipitation (the highest concentrations being observed in sleet and the lowest in pure snowfall). In rainwater as well as in waters of the unsaturated and saturated zones, quantities of the five chemical elements appeared in the following decreasing order: Fe>Zn>Mn>Sr>Ba and Sr>Ba>Fe>Zn>Mn. The chemical composition of infiltration waters in the carbonate massif changes vertically. The fundamental trends in the waters of this area include an increase of Sr and Ba concentrations, a decrease of the concentration of Zn, and static concentrations of Fe and Mn. © 2015, Polish Society Magnesium Research.

In the years 2009-2010 hydrological mapping and phytosociological releves (according to Braun-Blanquet methodology) of 21 spring niches were done. Basing on these investigations values of ecological indicators after Zarzycki were calculated: T - temperature, W - moisture, Tr -trophy, R - acidity (pH), H - organic matter content, L - light. T values correspond to microclimate from cold to moderately warm one. They indicate interdependence with spring exposure and thermal conditions of the water. W values correspond to intermediate habitats between fresh and moist ones. They are connected with depth of occurrence of the first aquifer. Tr values indicate the abundance of mainly nitrogen in water and soil what is confirmed by higher concentration of NO3 in water. R values correspond to a habitat with neutral reaction (pH), typical of water circulating in the environment of carbonate rocks. H values are characteristic to soils from mineral-humus type to organogenic ones and they show relationship with Eh values in the water. Making up hydrogeological investigations with phytoindication ones will widen range of recognition of the Jurassic hydrogeological environment.},

They are slightly mineralized water, mainly of hydrochemical type S04-Ca, sometimes So4-HCO 3-Ca. Groundwater of the gypsum series also modifies the chemistry of groundwater in the Upper Cretaceous which occurs in intermediate flow systems. On the base of hydrochemical investigation it has been stated that in the shallow flow systems simple ionic forms are dominant and presence of sulfate forms is observed too. Water circulating in gypsiferous series is oversaturated with regard to calcite and its chemistry is close to equilibrium with gypsum with tendency to oversaturation with growing depth of circulation.},

The area investigated is the Jura Krakowska (South Poland) - an area of upland merokarst (or relict karst), where the Upper Jurassic aquifer is mainly unconfined. The method applied is a combination of a simulation model of the groundwater aquifer (factors: net recharge; hydraulic conductivity; groundwater flow velocity in the aquifer) and a geographical information system - GIS model (depth of groundwater table; lithology of vadose zone; thickness of Upper Jurassic aquifer), and additionally a soil factor was taken into account. In the area of the Jura Krakowska, 5 classes of intrinsic vulnerability to pollution were distinguished according to the values of vulnerability factors. These classes range from extremely high to low vulnerability (IP 200-50). Based on the synthetic map of vulnerability it emerges that high vulnerability indices cover 54% of the area studied while medium and low vulnerability indices cover 46% of this area. The modified DRASTIC method presented seems to be a useful tool to evaluate the intrinsic vulnerability of karst-fissured aquifers of "Torcal" type with a scattered system of recharge and discharge, and a thick vadose zone of variable permeability. This is consistent with the method developed with European programme COST ACTION 620. All rating methods recommended for karst have limitations, therefore the method applied is constantly updated. Many of them are particularly useful for areas of bare karst, mountain systems of "Aliou" type and in areas of complete karst development (holokarst).},

abstract = {A karst-fissured aquifer in the Upper Jurassic carbonated rocks of the Krakow Upland shows a very high yield (safe yield 117 000 m3/day) and belongs to the major groundwater basins (MGBs) of Poland. The uncovered character of the aquifer and its hydraulic structure favor the intensive infiltration and migration of anthropogenic pollutants from the surface. This pollution is caused by agriculture and industry in the proximity of Krakow and the Upper Silesian agglomeration. Progressive degradation of groundwater quality on a regional scale results. Evaluation of the endangering of the aquifer studied is based on the analysis of the time interval of vertical water percolation from the surface, the time interval of groundwater horizontal flow through the aquifer and the duration of water residence in the aquifer derived from tritium data. Quaternary and Cretaceous overburden occur in the Krakow Upland in addition to numerous out-crops of limestones. The time interval of vertical water percolation in highly permeable limestones does not exceed 3 years and in the areas covered by overburden it is from several to 50 years. The mean effective time interval of horizontal groundwater flow through the Upper Jurassic Rocks along the flow paths ranges from several months in the areas of direct drainage to over 15 years in the elevated areas of local groundwater divides. The age of water in the rock matrix was determined using tritium data interpreted according to an exponential model and it ranges from 70 years to over 130 years. In karst-fissured systems with a high retardation index (R(p) = 21) the effective time of water circulation in local drainage basins does not exceed 7 years.

abstract = {This paper presents the karst phenomena at Wieliczka, which occur within salt and sulphate rocks. Karst processes have been analyzed in vicinity of gallery Mina, where in April 1992 mining operations disturbed the stability of the cap rock isolating rock salt deposit from the inflow of allochthonous waters. From April 1992 to August 1994 three cycles took place, during which rock masses were transported and removed from the Miocene strata. Intensity of these movements decreased in time. Quantitative description of karst phenomena being examined are presented in Tables 1-3. It is very likely, that so called denudation megacycle may occur again in the future.},

abstract = {Describes hydrochemical investigations in the Upper Vistula River and some of its tributaries from the Upper Silesian Coal Basin. The total volume of waters being pumped from coal mines directly or indirectly to the Vistula River is about 514.24 m3/min. These waters show a high degree of diversification of mineralization. About 210.0 m3/min of waters have TDS below 1.5 g/dm3, while 299.5 m3/min have content of TDS 1.5 to 70.0 g/dm3 and about 4.74 m3/min have TDS above 70.0 g/dm3. The Vistula River waters near Goczalkowice, before collecting the mine outflows, are characterized by mineralization of about 0.3 g/dm3 and by hydrochemical type of HCO3-SO4-Ca. Waters at the Bierun Nowy and Dwory water level gauges, that is after inflow of mine waters, have mineralization of 3.3-3.5 g/dm3 and 2.4-3.1 g/dm3 respectively. They are waters of the Cl-Na hydrochemical type. -from English summary},
