Abstract

Introduction. Assessment and study of the ecological and geochemical characteristics of groundwater and determination of their compliance with environmental standards is a relevant area of research, as these waters are used by the population for domestic and drinking purposes.

Purpose of the article. Analysis and assessment of ecological and geochemical indicators of groundwater within the Boryslav-Pokuttia Zone of the Carpathian Foredeep, identification of natural and anthropogenic influences, and determination of their compliance with environmental standards.

Research methods. The results of analytical determinations of 35 water samples from shallow wells and boreholes used by the population for domestic and drinking purposes are presented. To establish the status of groundwater, the maximum permissible concentration (MPC) standards for sanitary and chemical indicators of drinking water safety and quality, as well as indicators of physiological compliance with the mineral composition of drinking water, were utilized. Statistical, analytical, and graphical visualization methods were used to process and interpret the results of water analyses.

Results. The composition of the studied waters varies from hydrocarbonate calcium to chloride calcium-sodium. Statistical analysis of the data on the content of macroelements in groundwater showed abnormal variation in the concentrations of chlorine, sodium and potassium, mineralization and magnesium.

A close linear positive correlation between Pearsonʼs correlation coefficients between mineralization and concentrations of Na+ + K+, Ca2+, Mg2+, Cl− and permanganate oxidability was established, indicating the presence of a single process of groundwater enrichment with these ions.

It has been established that the main processes affecting the geochemical composition of groundwater are water-rock interaction and evaporation, which is particularly clearly illustrated by two samples from wells in the Volia Blazhivska village.

The graphs showing the interdependence of sodium and chlorine concentrations demonstrate increased concentrations of these ions in groundwater, which are caused by the dissolution of halite and the amount of atmospheric precipitation. The graph of the ratio (HCO3− + SO42−) and (Ca2+ + Mg2+) indicates the dominance of cation exchange processes in the studied aquifer.

Conclusions. It has been established that the main factors influencing the chemical composition of groundwater within the Boryslav-Pokuttia Zone of the Carpathian Foredeep are water-rock interaction, evaporative concentration and anthropogenic impact. Exceedances of sanitary and chemical safety and quality standards for drinking water have been identified in terms of total hardness, permanganate oxidisability, chloride content, total salt content and nitrate content. Non-compliance with the standards for the physiological adequacy of the mineral composition of drinking water is recorded for calcium, potassium, sodium, total salt content, total hardness, alkalinity and magnesium content, which makes them of limited suitability for human consumption. However, the majority of samples showed no deviations from the normative values for the indicators assessed.

Abstract

In this article, the authors examined 15 sources in Lviv and the surrounding area. Sanitary-chemical indicators and quality of spring waters were assessed. It is established that in 2024 оnly 2 springs are suitable for human consumption: “Spartak” and the source in Bryukhovychy. In all other springs many water quality indicators exceed the maximum permissible concentration (MPC): mineralisation, hardness, sulfates, calcium and nitrates. In two sources (High Castle and “Green Eye”) we observe an excess of nitrates. In the spring on Bilogorshcha we observe a slight excess of the mineralization index. Мost of the investigated waters are very hard, source “Spartak” – moderately hard. Nitrite and ammonium content was not detected in any water sample. The concentration of sodium ions in all sources of the city of Lviv and its surroundings is within normal limits and does not exceed the MPC. Chlorides are determined within normal limits in all selected samples, no exceedance of the maximum permissible concentration (MPC) is observed. Sulfates are present in all samples, but only in the source on Bilogorshcha they exceed the MPC norm by 1.5 times. Most of Lviv’s springs are calcium bicarbonate in composition. And only the source on Bilogorshcha is atypical in chemical composition – calcium sulfate. Such indicators are probably related to water-bearing rocks – gypsoanhydrite deposits of the Tyrrhenian Badenian aquifer.

A comparative analysis of ten popular sources in the city of Lviv was conducted over 14–15 years. The “Spartak” spring has remained suitable for human consumption for 18 years and the water from this spring meets the requirements for drinking water. The source in front of Vynnyky Lake was suitable for human consumption in 2010, but in 2024, due to an excess of calcium ions, it became unfit for consumption. Other springs also remain unfit for human consumption. Significant changes are observed in the nitrate content in the spring in Stryisky Park: over the past 15 years, the concentration of nitrates has decreased sixfold and no longer exceeds the MPC. Positive dynamics in the purification of the mineral composition of groundwater are observed in the springs at High Castle (the content of Calcium and nitrates is still above the MPC) and in Stryisky Park (the concentration of Calcium and hardness is above the MPC). The spring in Kleparov would have good characteristics, but the high calcium content excludes it from being suitable for human consumption and provokes an increase in hardness.

Abstract

The aim of the work was to quantitatively characterize the spatial‑stratigraphic variability of mobile forms of lead (Pb), cadmium (Cd), arsenic (As) and mercury (Hg) in peatlands of the Lviv Region and to identify the main physicochemical factors of their accumulation.

Materials and methods. 26 samples from six peatlands (Bilohorshcha, Honchary, Hamaliivka, Artyshchiv, Polonychna, Sknylivok) were studied along profiles 0–140 cm at 20 cm intervals. Mobile forms of Pb, Cd, As were determined by ICP AES after extraction with 0.2 M HCl, whereas Hg was measured by direct thermal decomposition-amalgamation AAS (NIC MA 3 Solo) without prior wet extraction. pH, ash content (Ash), moisture content (W), and organic matter content were measured. Statistical processing included descriptive statistics, geoaccumulation index (GI), Spearman correlations, hierarchical clustering (Ward) and PCA with varimax rotation.

Results. The studied peat deposits of the Lviv Region are characterized by a high proportion of organic matter (median = 83.95 %), variable ash content (9.69–37.08 %) and an acidic-to-weakly neutral environment (pH = 4.40–7.69). Mobile forms of Pb, Cd, As and Hg show high spatial stratigraphic variability and lognormal distributions; coefficients of variation are ≈ 236–263–136 % for Pb, Cd and Hg, respectively, while As has moderately high variability (≈ 82 %). According to the averaged concentration coefficients normalized to the median, the geochemical spectrum is: Cd (3.57) > Pb (3.02) > Hg (1.28) > As (1.20). Comparison with lithospheric and soil reference levels indicates persistent enrichment in Cd, whereas Hg is generally at background to subbackground levels (Igeo ≤ 0), with Pb and As mostly not exceeding background except for local anomalies. The vertical structure is mosaic: Hg shows modest near-surface increases with no stable deep maxima and no significant geoaccumulation (Igeo < 0); Pb frequently peaks near the surface but exhibits a deep maximum in the Honchary profile (60–80 cm); Cd forms contrasting intraprofile anomalies (Honchary, 60–80 cm), and As combines near-surface increases with a deep peak (Hamaliivka, 120–140 cm), indicating the role of redox gradients and mineral admixture. Multivariate analyses (correlation, clustering, PCA) before and after ash normalization consistently reveal a stable cationic Pb–Cd block, organic control of As, and moisture-redox-acid-base control on Hg, separating the roles of organic and mineral phases in forming profile anomalies and providing a basis for further monitoring.

Abstract

The aim of the research is to clarify the influence of the Badenian-Sarmatian sedimentary accumulation on the autochthonous part of the Precarpathian trough and the nature of consolidation and postsedimentation dislocations in the middle of the upper molasses. The research methods are based on a detailed correlation of well sections within individual megablocks of the Outer zone of the trough and a comparison of the obtained results, establishing the connections of the sedimentary accumulation with the paleogeomorphological features of the pre-Neogene erosional surface. The Miocene epoch of the development of the Outer zone of the Precarpathian trough was accompanied by regional transgression with the accumulation of a thick layer of Badenian-Sarmatian, mainly terrigenous sediments. The erosion system created in the early Miocene in areas not involved in the processes of the late Alpine orogenesis, preserved its main structural features under the layer of the upper molasses. The lithofacies features of the latter were directly dependent on a number of factors, the main of which are the lithological composition of the supply sources, the distance from the zone of active erosion processes, the mechanisms and routes of sedimentary material transportation, the mobility of the sedimentation basin and post-sedimentary transformations at different stages of sediment consolidation. The granulometric composition, the degree of sorting and the heterogeneity of the clastic material were largely controlled by the paleorelief of the bottom of the sedimentation basin and its dynamics. The main factor in the formation of discontinuous and plicative dislocations within the upper molasse complex were the forces of gravity, which were especially activated in areas with significant slope steepness. This led to the formation of regional and local slip-landslides, which were accompanied by antithetical (compensatory) disturbances.

Abstract

The paper addresses to the topical scientific and practical issue of enhancing the efficiency of hydrocarbon recovery from reservoir rocks formed in thin-bedded Neogene deposits of the Bilche-Volytska zone in the Precarpathian Basin. The reservoirs in this region are characterized by complex lithological structure, significant layering, variability in granulometric composition, and generally low filtration and storage properties. An additional complicating factor is the high heterogeneity of the strata, which manifests itself in both horizontal and vertical directions, significantly affecting the efficiency of oil and gas extraction using traditional methods.

The paper provides a detailed analysis of the geological prerequisites for the formation of thin-bedded sandstone-siltstone complexes, including their petrophysical characteristics, such as porosity, permeability, cementation type, and fluid saturation degree. Considerable attention is paid to the study of the filtration properties of rocks in the context of the spatial variability of reservoir parameters that determine the productive potential of wells. The influence of structural and tectonic factors on the formation of traps and the distribution of reservoir zones is considered separately.

The main factors limiting well yields in such geological conditions are analyzed, and possible ways to optimize development are considered. Improving geological and geophysical models, applying modern intensification methods, in particular hydraulic fracturing and acid treatment, as well as introducing technologies for detailed zoning of productive intervals, are promising areas for improving production efficiency. The work emphasizes the importance of a comprehensive approach that combines geological analysis, laboratory research, and modelling of filtration processes to ensure the rational and efficient development of resources in this complex category of reservoirs.
