The People

The Ruhr, with an average flow of 80.5 m3/s at its mouth, is a comparatively small tributary to the Rhine River that has to perform an important task: to secure the water supply of more than 5 million people and of the industry in the densely populated region north of the river. The complex water management system and network applied by the Ruhrverband in the natural Ruhr River Basin has been developed step by step, over decades since 1913. And from the beginning, its major goal has been to achieve optimal conditions for the people living in the region. For this purpose, a functional water supply and wastewater disposal infrastructure has been built up. The development of these structures required and still requires multi-dimensional planning and performance. Since the river serves as receiving water and at the same time as a source of drinking water, the above-standard efforts of Ruhrverband for cleaner water also help to conserve nature and wildlife. Ruhrverband has summed up its environmental awareness in the slogan: “For the people and for the environment”. This basic water philosophy, successfully applied to the Ruhr for more than 80 years, will be continued in accordance with the new European Water Framework Directive, enacted in 2000, which demands integrated water resources management in natural river basins, by including the good ecological status of surface waterbodies as an additional goal.

Наведено результати досліджень вмісту солейважких металів у природних водоймах Полтавськоїобласті. Підкреслюється, що одним із забруднювачіввододжерел є хімізація сільського господарства. До-слідження проводились у 2008–2012 роках на базіПолтавського обласного державного проектно-технологічного центру охорони родючості ґрунтів іякості продукції. Результати їх показали, що пере-вищень ГДК не спостерігається, отже, є передумовидля ведення в регіоні екологічного землеробства. Од-нак необхідною передумовою цього є наявністьоб’єктивної інформації щодо агроекологічного стануґрунтових і водних ресурсів, а також впровадженняекологічно безпечних технологій вирощування сільсь-когосподарських культур. The research results of the salt content of heavy metals in natural waters of the Poltava region have been shown. It is emphasized that one of the pollutants of water sources is chemicalization of agriculture. The studies were conducted in 2008-2012 on the basis of the Poltava Regional State Technological Design Center to protect soil fertility and quality. The results of studies showed that overrunning of maximum permissible concentration is not observed, therefore, there are prerequisites for doing organic farming in the region. However, a prerequisite to this is the availability of objective information concerning the agro-ecological status of groundwater and water resources, as well as the introduction of environmentally friendly technologies of growing crops.

Depletion Risk

At the present time water resources in the Republic of Bashkortostan (Russia) are exposed by negative anthropogenic influence. Natural processes also contribute to the depletion of water resources. The implementation of the water management system raises a number of methodological problems: the uncertainty of the criteria for assessing the ecological status of water bodies; the complexity of the relationship between the quantitative and qualitative characteristics of the water body due to the regional natural, anthropogenic, climatic features of the territory. The aim of this study is to development of a method for calculating the risk of water resources depletion. The method was tested on the river Belaya (Republic of Bashkortostan, Russia) catchment area. In calculating of water resources depletion risk several parameters were taken into account in particular: the area of watershed, catchment data of surface water and groundwater, data of land use, the average annual runoff, karst phenomena, vegetation. In this paper we use the method of import of geo data containing the soil composition, vegetation, geological structure and forest to assess the ecological condition of the river Belaya. There are defined the catchment areas of the river Belaya, which required immediate management solutions. Mapping of the Belaya River catchment areas requiring immediate management decisions was carried out.

Regions of the Russian Federation classified among Arctic zone estimated to 22% of Russian territory. Arctic is characterized by the richest reserves of natural resources, and its phased, balanced development is the most important strategic task of Russia’s socioeconomic development. Production and household activities of the population of Russia living and working in the far North is associated with difficult climatic and geographical conditions. In this case, the constant cold and consumption of contaminated water can lead to aggravation of various human disease. The Arctic zone of the Russian Federation is characterized by the richness of water resources as rapidly renewable (river runoff and its underground component), and static one to which are assigned the waters of lakes, underground waters, waters (ice) of mountain and polar glaciers. A characteristic feature of water consumption in the Arctic regions is the active use of lake water, which in a number of settlements is the main source of drinking water supply. In this regard, the assessment of the lake’s fund of Arctic zone and its ecological status is extremely topical.According to the assessments, more than 2.5 million water bodies, that is a ~2/3 of all water bodies of the country, are decoded in the Arctic zone of the Russian Federation on satellite images. Mainly, these are small water bodies, only about 975 thousand of them exceed 1 ha. The total area of the water surface of Arctic lakes is ~160 thousand km2 (slightly less than a half of the total water surface of all natural water bodies of the Russian Federation), and the total volume of water enclosed in them is ~760 km3.Even in the middle of the 20th century, the lakes of the Russian Arctic, with rare exceptions, were characterized by the highest quality of their waters, but by now the ecological status of many water bodies has deteriorated significantly. The vulnerability of Arctic lakes to pollution is enhanced both by virtue of the peculiarities of their orometry and by the simplicity of the biological communities of northern ecosystems characterized by a low degree of stability. The poor knowledge of Arctic water bodies does not allow taking the necessary preventive measures for their protection and rational use. In this connection, attention to the expansion of works on the integrated study of limnology of water bodies included in the lake fund of the Arctic zone should be paid.An estimation of water resources of lakes of the Arctic zone of Russia, their ecological status and the questions of etiology of diseases on the territories of the Far North are given in this article. The morbidity of the population of the Arctic regions of Russia today is much higher than the national average. Further development of the territory and the observed warming of the climate will lead to increasing pollution of freshwater resources with toxic substances, pathogenic microorganisms and viruses. This will exacerbate the issue of ensuring environmental safety and meeting the needs of the population in quality drinking water. The situation is further aggravated by the fact that the most affordable technologies for water treatment and wastewater treatment in conditions of low temperatures and high content of humic substances in the initial water cannot ensure the proper level of disinfection. In this regard, one of the topical issues is the creation of innovative technologies for water purification that are more adequate to the conditions of the Arctic zone of Russia.

The objective of this paper is to identify the level of changes in the ecological status of surface reservoirs of Dnipropetrovsk region under the impact of anthropogenic factors and to find a rationale for the limit loads on aquatic ecosystems, based on a quantitative assessment of their assimilative capacity values using GIS-technologies.To characterize and evaluate economic activity in the river basins of Dnipropetrovsk re- gion, the data of state statistical reporting by the form of 2-TP "Water resources management" of the State Agency for Water Re- sources of Ukraine were used. Parameters characterizing the assimilative capacity of water bodies were determined by taking into consideration the perennial average values of river runoff resources of the priority watercourses of Dnipropetrovsk region in the years with varying degrees of supply: with an average (50%), a low (75%) and a very low (95%) river water content. The main indicators characterizing the assimilative capacity of the water bodies of Dnipropetrovsk region are actual and necessary multiplicity of waste- water dilution, the limit to assimilative capacity of surface reservoirs, index of assimilative capacity utilization of river runoff re- sources of varying degrees of supply. A classification that characterizes the level of assimilative capacity utilization for water bodies is proposed. The level of assimilative capacity utilization of the Dnipro River in the reservoir areas, regardless of the degree of river runoff supply, is estimated as “allowable” . At 95% degree of river runoff supply, the level of assimilative capacity utilization of the Oril and Vovcha Rivers is characterized as “moderate”, the Samara River (after the confluence with the Vovcha River) as “high” and the Ingulets River with tributary the Saksagan River, and the Samara River (before confluence with the Vovcha River) as “veryhigh”. It should be noted that irrespective of the level of river runoff supply, the index of assimilative capacity utilization of the Samara River (before its confluence with the Vovcha River) exceeds the limit value by 19-115 times. For the spatial analysis of hydrological parameters and visualizion of the data in the form of thematic maps, the geoinformation system “Rivers of Dnipropetrovsk region” was developed on the basis of the ESRI ArcGIS Desktop10 software package. Using the geoprocessing tools, on the basis of hydrological indices of 7 priority watercourses for each of the 22 administrative-territorial districts of Dnipropetrovsk region, the main indicators characterizing the assimilative capacity of water resources were calculated and ranked. The use of indicatorscharacterizing the assimilative capacity of river runoff resources allows us to identify the threshold levels of anthropogenic transfor- mation of aquatic ecosystems, develop and implement environmental measures to improve the ecological status and ensure environ- mental safety of surface reservoirs.

The Impact

Despite being a natural phenomenon, water scarcity is, to a great extent, human-induced, particularly affected by climate change and by the increased water resources vulnerability. The Water Framework Directive (WFD), an ‘umbrella’ directive that aims to provide holistic approaches to the management of water resources and is supported by a number of Communication documents on water scarcity, requires for prompt responses to ensure ‘healthy’ water bodies of good ecological status. The current paper presents a multidisciplinary approach, developed and engaged within the Globaqua Project, to provide an assessment of the main challenges towards addressing water scarcity with emphasis on the climate change projections, in two Mediterranean regions. The current paper attempts to critically assess the effectiveness of the WFD as a tool to address water scarcity and increase sustainability in resource use. Criticism lies on the fact that the WFD does not directly refer to it, still, water scarcity is recognized as a factor that increases stress on water resources and deteriorates their status. In addition, the Program of Measures (PoMs) within the WFD clearly contribute to reducing vulnerability of water resources and to ensure current and future water use, also under the impact of the projected climate change.

Purpose. To analyze the relationship between the ecological status of water bodies and the size of the tax rate for groundwater extraction. Methods. A complex of general scientific methods of research was used. In particular, a comparative analysis of the level of tax rates for the extraction of groundwater in the EU member states. Results. A comparative analysis of the level of tax rates for groundwater extraction in the EU member states has been made.The issue of allocating state income from rent payments for groundwater extraction has been investigated. It has been established that the cost of rent payments from groundwater extraction is usually attributed to: general taxation (Denmark, the Netherlands, Germany), water resources management (France), fund for the protection and restoration of groundwater (Belgium, Germany), expenditure on water resources (provinces in the Netherlands, Australia).The modern ecological status of water objects of EU countries has been studied. It has been established that rent payments for groundwater extraction in the EU member states vary considerably. The smallest are observed in the post-Soviet area (Estonia, Hungary, Latvia, Lithuania). The highest tax, among the countries under study, in Denmark. Denmark is leading the quality indicators of underground and surface waters. 70-90% of water bodies in Denmark have a good ecological status.Conclusions.It has been practically proved that the high tax rate for the extraction of groundwater does not solve environmental problems. The experience of European countries shows that the improvement of the ecological status of water objects is possible by budget allocations from the extraction of groundwater to the management and protection of water resources.

Water resources are the national wealth of each state, an important natural resource, and determine the development opportunities of most sectors of the economic complex of Ukraine. The Southern Bug River is the largest river, the basin of which is completely located in Ukraine. Due to the intensive growth of anthropogenic impact on the studied reservoir and the economic use of its resources, the quality of water in it has significantly decreased. To improve the quality of water in rivers, it is optimal to use biotechnological methods, which provide many opportunities for effective solutions to issues related to monitoring, assessment, and treatment of polluted watercourses. The aim of our study was to assess water safety, the current ecological status of the Southern Bug River within the Khmelnytsky region in three areas (Maryanivske Reservoir, Kopystyn, Shchedrivske Reservoir) and use in domestic needs, with analysis of potential risks to human health, development of new biotechnological and improvement of existing measures to improve water supply. The experimental part of the work was performed on the basis of the Khmelnytsky Regional Department of Water Resources in the laboratory at the address Khmelnytsky, st. Soborna, 29. We conducted a chemical assessment of the Southern Bug River on three indicators: salt composition (I1), tropho-saprobiological (I2), and specific toxic substances (I3). Research of river waters was carried out in order to control the MPC (maximum permissible concentrations) of substances for use in household and food needs of the population and to propose biotechnological methods of river water purification within the Khmelnytsky region. According to our research on hydrochemical characteristics, the water contained elevated levels of NH4, NO2, NO3, PO4, the average values of HSC (chemical oxygen demand) exceeded the MPC in all areas by 2 to 5 times. This may be due to exposure to organic compounds of natural origin. The content of nitrites, nitrates is within normal limits, but the content of ammonium salt exceeds the MPC up to 20 times in the village Kopystyn and from 2 to 7 times in the village of Letychiv. According to many indicators of the salt block, the maximum concentration limit was not exceeded, except for the village Kopystyn, the concentration of Magnesium (Mg) was 84.33 mg/dm3 at a rate of 40.00 mg/dm3. According to specific toxic substances, the water belonged to the III class 4 quality category, Chromium (Cr) was not detected, Manganese (Mn) and Copper (Cu) were within normal limits, although the Copper content was high. The concentration of Iron (Fe) varies in different areas and during the year, there is a case of excess Iron in the village. Kopistin up to 0.86 mg/dm3 at a rate of 0.30 mg/dm3. Iron affects the intensity of phytoplankton development and the qualitative composition of the microflora, so its concentration is subject to seasonal fluctuations. To improve the quality of water in the Southern Bug River, we have proposed the use of biotechnological methods, including those that provide many opportunities to effectively address issues related to monitoring, assessment, and treatment of polluted watercourses.
