MONITORING AND ASSESSMENT OF IMPACT OF MUNICIPAL SOLID WASTE LANDFILLS ON THE SURFACE WATER QUALITY IN THE ADJACENT PONDS
Authors O.T. Azimov, Ye.M. Dorofey, O.M. Trofymchuk, I.V. Kuraeva, K.S. Zlobina and S.P. KarmazynenkoSummaryThe monitoring ecological hydro-geochemical investigations for the surface waters of the north-western part of Landfill No 5 for the municipal solid waste disposal and the adjacent area are carried out. Based on analyses of surface water samples taking from the existing ponds, it was found that they are polluted by wastewater with the high content of organic toxicants predominantly. Most likely the latter comes from both the Sections and ponds-collectors of leachate or from the pig farm, which is located near the Landfill but hypsometrically higher in relief. In order to specify the answer the more studies are required. Contrary, surface waters beyond the Landfill area are characterized by the ecological and hydrogeochemical indicators, which no higher than the maximum allowable concentrations, although they are higher than the background ones. This indicates that the considerable outflow of chemical pollutants together with the surface waters from the north-western Landfill No 5 area beyond of its borders during for more a year is absent. Only the short-time periodic monitoring of the water bodies within the territory of interest able to determine such time intervals when water could be polluted by various toxicants.

LONG-TERM DYNAMICS AND CURRENT TRENDS IN FLUCTUATIONS OF THE FLOW CHARACTERISTICS OF THE SIVERSKYI DONETS RIVER BASIN
More LessSummaryLong-term fluctuations of average annual flow, maximum flow of spring flood, warm and cold period’s floods, the minimum flow of the winter and the summer-autumn low periods of the Siverskyi Donets River Basin are analysed. A decrease in the minimum characteristics of winter flow (winter low period) and maximum flow characteristics of the cold flood were found. The lows and highs of flow of the cold period do not significantly differ from the lows and highs of the warm period at the present period (2008–2017). Three groups of rivers are identified for belonging to a particular part of the Basin. Differences in trends of flow fluctuations for the Left-bank, Right-bank tributaries and the Siverskyi Donets River are analyzed. Some differences in the fluctuations of the flow of the Left-bank tributaries and, in particular, of the Siverskyi Donets River and, separately, of the Right-bank, were revealed. It is established that there is a dry phase from 2008 till nowadays on the rivers of the Siverskyi Donets River Basin.

MULTIPURPOSE CLASSIFICATION OF THE SUBSYSTEMS OF GEOLOGICAL-ECOLOGICAL SYSTEM OF THE BLACK SEA BOTTOM DEPOSITS
More LessSummaryAnalysis of the properties of the internal geological and ecological conditions of different spatial components of the geological-ecological system of bottom sediments of the Black Sea, as well as the processes of their interaction with external natural and anthropogenic-natural systems and other objects allowed the author to distinguish in the Black Sea a number of subsystems, to classify them according to specific characteristics and to assign them to different taxa (classes, groups, types, species, etc.) of the multipurpose classification of the subsystems of geological-ecological system of the Black Sea bottom deposits. The Classification was developed by the author using the theoretical and methodological fundamentals of marine geoecology and based on geo-ecosystem analysis of a considerable amount of geological, engineering-geological, oceanographic and ecological data, including data on the substance-genetic composition of bottom deposits, characteristics of structural links between their geo- and bio-constituents, etc. The presented Classification can be used as a basis for solving a number of fundamental and applied problems of marine geoecology, in particular at the stage of development of projects of construction of underwater hydraulic structures and communications, resource development, geo-ecological zoning, planning and implementation of monitoring, etc.

MODELING IN MONITORING SYSTEM OF UNDERGROUND HYDROSPHERE FOR TERRITORIES UNDER TECHNOGENIC PRESSURE
Authors O. Koshliakov, O. Dyniak and I. KoshliakovaSummaryThe authors provide evidence of the necessity to take into account underground hydrosphere state in assessing the stability and dynamism of urban natural-technogenic geosystems. This is because groundwater disturbance often leads to the emergence or activation of negative engineering-geological processes and even hazards. Detailed hydrogeological study of the territories in order to assess the existing natural-technogenic situation requires a change in classical approach to underground hydrosphere monitoring. It is proved that the use of statistical modeling based on spatial analysis and modeling in GIS allows the most efficient use of a small input data amount and to make prediction with the help of deterministic mathematical modelling.

LEGAL REGULATION OF GROUNDWATER EXTRACTION PROCESSES TO SUPPORT THE NEEDS OF MILITARY UNITS
Authors S. Pasika, D. Chomko, O. Opanasenko, D. Khomiakov and O. SkybaSummaryThe article analyzes the legal and normative acts that regulate certain issues of groundwater extraction processes to meet the needs of the Armed Forces of Ukraine. Reviewed and analyzed are the general trends of groundwater extraction for the needs of the military units as components of national security and defense of Ukraine. Absence of a system in the legal regulation of groundwater extraction to meet the needs of military units poses a real threat to the national security and defense of Ukraine, so the above topic is extremely relevant in the current context. Today, with insufficient resources, inefficient environmental monitoring and ineffective use of resources in the security and defense sector, the issue of legal regulation of groundwater extraction to meet the needs of the Armed Forces of Ukraine as a component of Ukraine’s national security and defense is quite urgent.

MONITORING OF THE STATE OF THE GEOLOGICAL ENVIRONMENT AND ANALYSIS OF THE OF SUBMARINE VOLCANISM IMPACT ON THE GEOECOLOGICAL CONDITIONS OF THE BLACK SEA DEEP SEA ZONE
Authors V. Iemelianov and O. IvanikSummaryThe Black Sea is a unique geo-ecosystem with special hydrological, geochemical, geological and biotic subsystems. The environmental ecological subsystems of the Black Sea geo-ecosystems, namely marine aerial, aquatic and marine geological ecosystems, have certain natural features of internal ecological conditions. Wide development of gas- and mud volcanic processes in the deep sea zone of the Black Sea and the dissemination of gas emissions mainly of methane composition have a huge impact on the material composition of the components, the physical-mechanical and engineering-geological conditions. This necessitates monitoring studies of the state of the geological environment of the Black Sea because of the need to identify and understand the features of the temporal and spatial dynamics of its degassing processes. A comprehensive study of gas volcanism, gas discharge and gas hydration phenomena of the deep sea zone of the Black Sea, showed that submarine mud volcanoes and methane eruptions are not only a reliable indicator of prospects for the detection of offshore hydrocarbon fields, but also is a very important factor of the geosystem existence. In the development of special technologies, reactive gas emissions can become a promising source of hydrocarbons as an energy resource.

THE METHODICAL APPROACH TO THE DETERMINATION OF GEOLOGICAL RESERVES CHEMICAL COMPONENTS IN THE PRODUCED WATER OF OIL AND GAS FIELDS
More LessSummaryThe produced water (PW) of oil and gas fields is a cost component of their development. The article determines that these waters contain a large number of dissolved chemical components. Components contained in PW have an industrial value. The authors point out that oil and gas companies can extract these waters from the cost component into the revenue component when extracting useful components from the PW. The authors state that geological and economic assessment is needed to use PW as a raw material. This paper proposes a methodological approach to the geological and economic assessment of chemical constituents in PW. The methodology is based on several basic criteria. The work identifies the volumes of extraction of PW, concentrations of chemical components, industrial concentrations, the term of development of the deposit are the main criteria for geological and economic assessment. The paper gives an example of determining the geological reserves of useful components at the Lelyakivskoye deposit. The authors classify these stocks according to the current regulatory documents. The result is that this technique allows these stocks to be converted from code 3.3.3 to code 1.1.2. The authors conclude that the code change should attract investors to the development of PW as a valuable resource.

VARIOGRAM ANALYSIS TO MEASURE THE SPATIAL STRUCTURE OF BRIOGEOCHEMICAL FIELD OF NORTHERN UKRAINE
Authors Yu. Tyutyunnik and O. ShabaturaSummary“Variogram analysis allows revealing the spatial structure of the biogeochemical data, to group elements according to their similarity of their biogeochemical behavior, and describe the mechanisms of their concentration in mosses. The concentration macroelements in moss make up a composite geochemical field that is determined by a combination of several factors: availability of mineral and chemical forms of elements for their assimilation, the presence and magnitude of the physic-biological barriers in the environment.
The most concentrated are the biophilic elements (S, P, K, Ca, Mg,) and B, which are capable of vigorous and strong biological adsorption. Excluding of K, their spatial size are beyond the limits of geostatistical study, meaning that they have an immeasurable scale. This is probably a reflection of the effect of the mineral substrate.
Such macroelements as Fe, Al, Na and K have a clear rank, which indicates the different size of the spatial factors and, probably, caused by a hydromorphic complex. The association of trace elements in moss have similar variogram with one rank, may be a reflection the territorial differences of the aerial fall-out of heavy metals.”

CLIMATE MONITORING DATA APPLICATION IN THE TECHNOLOGICAL REGIONAL ASSESSMENT SCHEME AND SIMULATION OF WATER FLOW
Authors S. Snizhko, O. Shevchenko, I. Didovets, O. Obodovskyi and O. PochaievetsSummaryA climate change monitoring system integrates satellite observations, ground-based data and forecast models to monitor and forecast changes in the weather and climate. A historical record of spot measurements is built up over time, which provides the data to enable statistical analysis and the identification of mean values, trends and variations. The better the information available, the more the climate can be understood and the more accurately future conditions can be assessed, at the local, regional, national and global level. This has become particularly important in the context of climate change, as climate variability increases and historical patterns shift (Climate Change Monitoring System. Until now, there are no standard methodologies, no standard scheme to correct using climate monitoring data for effectiveness assessment regional climate change and its impact on water flow in Ukraine.

OIL AND GAS PERSPECTIVES OF ATESHGAH STRUCTURE (BAKU ARCHIPELAGO) IN THE CONTEXT OF ITS GEOLOGICAL HISTORY
Authors V.Sh. Gurbanov, M.S. Babayev, N.R. Narimanov and S. ShpyrkoSummaryThere is a direct relationship between the deposition rate in a basin and the amount of accumulated organic matter. We try to establish the potential of relevant lithologic units as mother rocks, determining the depositional rates for different geological time spans based on the lithological and stratigraphic cross-section of the area. As case study, Ateshgah uplift is considered as a large offshore anticline structure in the central part of Baku archipelago in the Caspian Sea. From the reconstructed paleoprofiles (backstripping technique), the rates of the fold development depending on the geological epochs can be approximately assessed. Fold growth rates for this structure steadily increased throughout the time eventually reaching the values of 0.5–1.3 km/mln yr. This result is in agreement with similar paleographic reconstructions, recently reported for other prospective structures in the region. With the exception of Paleocene and Eocene, the remaining stratigraphic intervals were favorable for the accumulation of organic matter in potential mother rock at least exceeding the Clarke number.

THE USE OF GROUND PENETRATING RADAR TO IDENTIFY THE BURIED STRUCTURE IN THE CHURCH OF ST. ELIAS - BOHDAN KHMELNYTSKY BURIAL VAULT
Authors K. Bondar, R. Khomenko and A. ChernovSummaryThis paper shows results of investigations in St. Elias Church in Subotiv (Cherkasy region, Ukraine) using ground penetrating radars (GPR) VIY3–300 (300 MHz) and VIY3–500 (500 MHz). The church is known as family burial vault of Bohdan Khmelnytsky, the Hetman of Ukraine (1648–1657) and founder of the Ukrainian State. Anomalies were indicated at a time 51–125 ns (depth 2.1–5.4 m) in the centre of the nave. Archival materials and results of previous archaeological excavations were considered for the interpretation. An underground structure with area 3×2 m, probably faced inside with bricks and partly infilled with soil is predicted in church. The structure could be considered a burial crypt with entrance tunnel located at the western part of the nave.

DEVELOPMENT OF ALGORITHM FOR CALCULATING EXPOSITION VALUE OF CO2 CONCENTRATION IN AIR FOR TASKS OF MONITORING OF SOILS OF UKRAINE POLISSYA AGRO-LANDSCAPES
Authors O.I. Bondar, P.I. Trofymenko, N.V. Trofimenko, V.I. Zatserkovnyi and F.I. BorysovSummaryThe paper presents the results of field analytical studies and development of an algorithm for calculating the exposure value of CO2 concentration in the air of Ukraine Polissya agro-landscapes soils. A clear procedure for calculating exposure time for in situ studies is given, depending on the intensity of soil air exchange. Depending on the 6 types of air exchange intensity, approximate measurement time ranges are established to measure soils with too difficult, relatively difficult, satisfactory, good, very good and excellent intensity level of air exchange. It is defined that the time range of measurements of the value of CO2 concentration in the ground air, the soil organic matter reserves, as well as the determination of diffusion coefficients in situ conditions are in the range of 2 to 11 and more hours. In case of unsatisfactory values of soil diffusion coefficient (due to unfavorable granulometric composition, over-wetting, excessive compaction), the measurement time for carbon dioxide concentration in the ground air exceeds 5 hours. In the case of favorable values of D, the measurement time usually does not exceed 2–3 hours, characterizing this method of measurements as an express method.
