abstract = {Study Region: Southern Poland, Dunajec River catchment Study Focus: The study evaluated an eleven-year observation period of physicochemical parameters within a riverbank filtration (RBF) site located by the Dunajec River. A total of nine parameters (pH; electrical conductivity; sulphate; chloride; nitrate; manganese; water hardness; colour; turbidity) in both surface water and groundwater underwent statistical scrutiny. This analysis encompassed Spearman's correlation, linear mixed-effects models and hypothesis testing. New Hydrological Insights for the Region: This study revealed that the Dunajec River constitutes a major factor in forming the exploited groundwater physicochemical composition. Statistically significant differences between two rows of wells were found, implying a more substantial RBF impact on the row closer to the Dunajec. However, the river's influence on further wells was also highlighted. The RBF process in the study area was considered efficient since it maintained a stable groundwater physicochemical composition and provided sufficient water for exploitation over the years. Comprehending the interactions between the surface water and groundwater flow system is crucial to the well field sustainability, enabling water supply system optimisation and a more precise assessment of risks regarding groundwater contamination. © 2024 The Authors},

abstract = {This research aimed to assess the PPCP contamination of the water environment within the Silesian Province (southern Poland), where emerging contaminants are likely to occur due to urbanisation and industrialisation, especially in the central part of the voivodeship. An attempt was made to compare the PPCP occurrence in waters of areas that varied in land use and urban development, i.e. within the Upper Silesian Urban Area (USUA) and outside this region. The research was performed in selected areas of the province and involved sampling of raw and treated wastewater from four wastewater treatment plants (WWTPs), as well as surface water (9 samples) and groundwater (14 samples) in six pilot sites. In total, 102 PPCPs were analysed using the LC-MS/MS method. In the natural waters, physicochemical parameters were also measured, and the basic chemical composition of the samples was determined. In the wastewater samples, the number of detected substances and the total PPCP concentrations were up to 66 PPCPs and 1211.0 µg/L in influents, and up to 59 PPCPs and 174.1 µg/L in effluents. The values for the natural water samples were respectively up to 71 PPCPs and 172.2 µg/L in surface water, and up to 13 PPCPs and 1.5 µg/L in groundwater. The results revealed that wastewater discharges from WWTPs using conventional treatment methods serve as a significant source of PPCPs due to inefficient removal of the microcontaminants. The contamination level of the surface waters in terms of the PPCP occurrence and basic chemical composition was higher within the USUA, where rivers are recipients of wastewater discharges from WWTPs. The PPCP quantity in the groundwater samples did not vary greatly within and outside the USUA, likely due to hydraulic connection between rivers and aquifers or induced surface water infiltration that recharge aquifers in some of the selected areas. © 2024 Elsevier B.V.},

abstract = {Isotopic signatures of anthropogenic sulfate sources within the Upper Silesian urban area (southern Poland) were investigated to increase the reliability of the origin assessment of groundwater contaminants. To analyze δ34S and δ18O in sulfate, 64 samples were collected, representing several sulfate sources: synthetic and organic fertilizers, raw and treated wastewater, mine water, leachate from landfills, mine heaps, and industrial waste dumps. Additionally, 10 surface water samples were taken from contaminated rivers regarded as potential groundwater pollution sources. Results of δ34S and δ18O in sulfate derived from anthropogenic sources were compared with literature data, which indicated significant discrepancies for some contamination sources. The results were applied to assess SO42- origin in groundwater samples from the Gliwice aquifer. Apart from the δ34S and δ18O data, the study included measurements of major ions, inorganic nitrogen forms, trichloroethene and tetrachloroethene in groundwater. Isotopic analyses of river water samples confirmed the impact of urbanized and industrialized areas on surface water pollution and possible influence on groundwater contamination. The values of δ34S and δ18O similar to wastewater were reported for most groundwater samples from the Gliwice carbonate aquifer. Groundwater contamination was also manifested by higher values of electrical conductivity and concentrations of chloride, sodium, trichloroethene and tetrachloroethene. The comparison of recent isotopic data on SO42- sources with literature values clearly shows that it is very important to investigate local potential contamination sources to increase their reliability in determining the source of groundwater or river water pollution. © 2022 The Author(s)},

abstract = {The application of combined research methods, such as hydrochemical and isotopic anal-yses, facilitates understanding of the origin of water constituents and migration of contaminants in the aquatic environment. The presented study attempts to identify contamination sources affecting water quality within the Kozłowa Góra reservoir catchment area (southern Poland). A total of 100 water samples were collected from surface water (the Brynica river; streams; and the reservoir) and groundwater (a Quarternary aquifer) in four time periods. During fieldwork, the physicochemical parameters were measured (temperature; pH; electrical conductivity; redox potential; and dissolved oxygen). The chemical analysis included the determination of major ions (HCO3−; SO42−; Cl−; Ca2+; Mg2+; Na+; and K+), nutrients (NO3−; NO2−; NH4+; and PO43−), and total organic carbon. The study was complemented by isotopic analysis of sulphur and oxygen in sulphate, which enabled a more pre-cise identification of stressors affecting water quality in different parts of the catchment area. Chemical and isotopic results (δ34S = 4.38–13.99‰; δ18O 3.59–13.30‰) revealed that wastewater discharges and agricultural activities have a significant influence on the chemistry of the Brynica River and other streams. At some sampling points, a lower quality of water was manifested by elevated concentrations of NO3− (up to 22.6 mg/L) and several other ions (e.g.; up to 114 mg/L for Cl−; up to 51.52 mg/L for NH4+; and 12.5 mg/L for PO43−). The quality of groundwater was deteriorated mainly by infiltration of sewage from leaky septic tanks. The level of groundwater contamination varied depending on the location, as higher concentrations of major ions and values of electrical conductivity were observed in residential areas. The Brynica river, streams, and groundwater recharge the drinking water reservoir, and thus its quality depends on these sources. A dilution of water and the presence of biochemical processes led to a reduction of contaminant concentrations in the Kozłowa Góra reservoir (down to 3.5 mg/L for NO3−; 32 mg/L for Cl−; 0.21 mg/L for NH4+; and <0.05 mg/L for PO43−) compared to water in the river and streams supplying the reservoir. The study revealed the role of wastewater discharge and agricultural activities in the evolution of surface water chemistry. The results will be used in further research on the origin and migration of other substances in water, including microcontaminants. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {This paper addresses groundwater pollution and the potential presence of pesticides within the catchment areas of two reservoirs that are sources of drinking water. The two reservoirs are Goczałkowice and Kozłowa Góra, both in Southern Poland. Agricultural and rural areas dominate both catchments. Archival data showed local groundwater contamination with nitrates. This indicated the possible presence of pesticides in shallow groundwater. In total, 13 groundwater samples from shallow sandy aquifers were collected. All the samples were tested for the presence of 35 organophosphate pesticides and 28 organochlorine pesticides. Additionally, in order to determine the current groundwater conditions, physicochemical parameters were measured in the field, and water samples were subjected to analysis of their chemical composition (incl. the determination of nitrates). The research outcomes showed that pesticides were not detected above the detection limits in any of the samples. Due to variations in the persistence and degradation rates of pesticides, the occurrence of these substances in the groundwater environment and the possibility of their migration to aquifers should not be completely excluded. Natural processes and factors (e.g.; sorption; biodegradation; hydrolysis and redox conditions) may gradually reduce the pesticide concentrations in groundwater. The chemical analyses revealed high concentrations of nitrates in the groundwater. This suggests the possible influence of agriculture and fertilizer application on groundwater quality; however, a proportion of NO3- ions may be connected with improper sewage management within the two catchments. The absence of pesticides in groundwater impacted by agriculture may result from processes occurring in the aquifer and the rapid degradation of these compounds due to photolysis and prevailing weather conditions. In the vicinity of dwellings, nitrates also originate from domestic wastewater. Thus, the occurrence of pesticides in groundwater contaminated with NO3 cannot always be expected. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.},

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 = {A comprehensive study on the sources of groundwater contamination in the Triassic carbonate aquifer, southern Poland, was conducted. The Gliwice aquifer is an important source of potable water in the Silesia region, the most industrialized part of Poland. Groundwater quality has been deteriorating over the last decades, which encouraged researchers to undertake comprehensive study to identify the sources and fates of the observed pollution. The presented study comprised analyses of major and minor ions, trichloroethylene (TCE) and tetrachloroethylene (PCE), CFC-11, CFC-12, SF6, Ne and Ar in groundwater. The results showed that shallow groundwater within the Tarnowskie Góry town, located in the recharge zone of the aquifer, was more contaminated than groundwater abstracted from deeper part of the aquifer within the town, as well as groundwater located downgradient. A contamination plume of boron indicated an impact of the closed chemical plant, operating in the 20th century. Groundwater in the vicinity of the chemical plant was significantly altered, which was manifested by elevated concentrations of Cl−, SO4 2-, Na+, total Fe and Mn. The study revealed groundwater contamination with CFC-11 and CFC-12. Comparison of concentrations obtained in two field campaigns (in 2010 and 2015) showed an increase in the extent of pollution plumes. The third analysed gaseous tracer, SF6, did not appear to come from non-atmospheric sources, therefore, it was possible to calculate groundwater age using lumped parameter models. The results showed relatively young ages of the analysed groundwater samples, from 4 to 5 to 30–50 years. The youngest groundwater were found close to the Drama River, suggesting infiltration of the surface water into the carbonate aquifer. This feature of the river was confirmed by the observation of TCE and PCE concentrations in groundwater. Central part of the Tarnowskie Góry town was a source area for TCE and PCE contamination. Two directions of pollutants migration were observed, one of them was induced by the drainage of the historic ore mine and subsequently the Drama River – recipient of water coming from the mine drainage. © 2020 Elsevier Ltd},

abstract = {In order to determine geochemical processes affecting chemical composition of groundwater in the Gliwice- Łabedy well-field area two research methods were applied. Chemical analysis allowed us to assess the quality of groundwater in the Triassic karst-fractured-porous aquifer of the southwestern part of the major groundwater basin no. 330. The chemical composition of groundwater is distinguished by spatial heterogeneity highlighted by higher mineralization and concentrations of individual ions in the western area. In addition, all samples collected in 2016 were analyzed for the δ35S and δ18O to identify sources of sulfates in the waters examined. The study revealed a different origin of these ions depending on location of the wells sampled. The results of chemical analysis and archival data allowed for application of geochemical modeling in identification of processes taking part in groundwater chemistry evolution. Simulations of processes controlling water chemistry within the Triassic aquifer were conducted using The Geochemist's Workbench 10.0.6. The examined processes encompassed dissolution of minerals forming the carbonate aquifer and Miocene evaporates overlying the Triassic aquifer as well as mixing of groundwater and surface water. © 2018 Polish Geological Institute.
