Purpose. To perform a quantitative and qualitative impact assessment from point and diffuse sources of anthropo genic pollution on the Prut River basin within Ukraine. Methodology. Based on the developed statistical information and the use of the Guidance Paper on Impact Anal ysis and Risk Assessment in accordance with the EU Water Directive (EU project "Environmental protection of in ternational river basins"), load calculations have been carried out on four factors influencing the Prut ecosystem, namely, volumes of discharges of untreated sewage, the total share of sewage in the river, from agriculture and live stock production. findings. The main anthropogenic loads on the Prut river basin within IvanoFrankivsk and Chernivtsi regions of Ukraine from point and diffuse sources have been analyzed and calculated. In fact, it has been confirmed that diffuse sources are the main pollutants of the Prut ecosystem. Noncanalized area caused the emission of organic and nutri ent compounds into the river basin. According to the calculation of the indicators of diffuse load, water massifs in Kitsman, Kolomyia and Snyatyn districts are "possibly at risk" from agriculture, and in Hertzayivsky district-from livestock. The largest point polluters in the Prut River are communal enterprises of the settlements in Kolomyia and Chernivtsi. originality. The methodology for estimating loads on the river basin has been further developed by calculating load indicators, which allows the development and implementation of effective methods and tools for controlling the ecological safety of aquatic ecosystems. Practical value. The results obtained are the basis for adapting European approaches to integrated water resources management and developing measures to minimize the risks from human activities in the Prut basin. The work has been implemented at the national level in the process of drafting the Prut River Basin Management Plan in the frame work of the international project "Environmental protection of international river basins" (EPIRB) and improvement of the water monitoring system in the Carpathian National Nature Park.

The study solved the problem of analyzing the background spatial-factorial patterns of distribution of quantitative and qualitative indicators of groundwater sources and surface waters within the upper part of the Prut River that belongs to the Danube River basin. The studies have been conducted within the Carpathian National Nature Park, located on the northeastern slopes of the Ukrainian Carpathians. The basic regularities and peculiarities of the distribution of springs in the researched territory have been studied by means of factor analysis of the set of estimation parameters and the relationships between them. Patterns of changes in the concentrations of the natural components of the qualitative composition of the hydro-ecosystem have been found, depending on the altitude of the terrain. Similar data has been obtained in the analysis of the relationship between the average geometric components of the chemical composition of natural waters and the length of the river. Trend lines and equations have been obtained, which can be used to determine the background normative values of natural water components along the length of the stream and the altitude of the basin for individual seasons and phases of water. In this paper, for the first time, the functional natural pattern of hydro-ecosystems of the upper part of the Danube basin within the northeastern slopes of the Ukrainian Carpathians is shown to increase its qualitative potential with increasing absolute altitude above sea level for nature conservation territory.

The main object of research in this publication is the springs considered in the development system of the regional structural geology of the Carpathians. In specific theoretical and practical examples it proved that the springs can be indicators of linear faults. The effectiveness of combining field methods with remote methods for detecting geological explosive disturbances and fracturing of the local substrate has been proved. The prospects and directions for further research are shown.

The purpose of the study is to generalize methodological approaches to monitoring springs in the territory of the Carpathian National Natural Park and to identify the main hydrological and hydrochemical laws of their functioning. We conducted research of springs outlined outside the Carpathian National Natural Park (CNNP) – the first (1980) and one of the largest (504.95 km2) nature parks in Ukraine, located in the territory of Ivano-Frankivsk region. The office is located in Yaremche, Ivano-Frankivsk region. Inventory and accounting of springs is included in the plan of annual nature conservation activities held in the park. In 2019, after the grant of two wetlands in the Carpathian National Park (Prut and Pogorelets) international status and their inclusion in the list of wetlands protected by the Ramsar Convention on Wetlands of International Imports of International Imports especially as Waterfowl Habitat, 1971 – the study of environmental components, including springs, becomes more relevant and practical.There are all the necessary conditions for a comprehensive study of natural groundwater output to the surface – scientific, logistical and informational base. For the period 2011-2019 about 40 expeditions were conducted to study the springs located in three main natural complexes on the territory of the Carpathian NNP: the Outer Gorgany, the Yasinsky-Verkhovynsky intermountain basin, the Chernogora massif. In the hydrological aspect, it is a Prut river basin (left tributary of the Danube). The main methodological approaches for monitoring springs were developed and consistently implemented. The general monitoring algorithm, which is considered in the article, can be presented in the form of a flowchart with successive steps: 1) collecting available information about the springs 2) field surveys of the first level (description of the springs and their mapping) 3) field surveys of the second level (measuring flow rates and water sampling); 4) regular observations on reference springs. The water mineralization of most springs in the Carpathian NPP (about 90%) is in the range of “very fresh” and “normally fresh” – 30-500 mg/dm3 (according to the classification of Valentyn Khilchevskyi). There are springs with very low salt content – “extremely fresh” (10-30 mg/dm3), and sometimes “super fresh” with a salinity of less than 10 mg/dm3. Such a low level of spring water mineralization corresponds to the norms of the regional natural background of the salt content in unpolluted atmospheric precipitation.
