Since phosphates are ones of the key components causing eutrophication of water bodies, every country has to have clear legislation on them. Comparing standards of the EU and Ukraine concerning total phosphorous in wastewater, effluents from wastewater treatment plants (WWTPs), drinking water, and consumer detergents, the paper shows how the difference of legislation makes legal the eutrophication of water bodies in Ukraine. As demonstrated, the current Ukrainian regulations do not oblige strictly municipal WWTPs to remove phosphorus compounds from wastewater, although the EU has rigid requirements therein. Instead, Ukraine forbids discharging wastewater with more than 5 mg/l of total phosphorous into the municipal sewage system, though many local regulations in EU-countries allow higher values, e.g. such cities of Germany as Berlin, Hannover, and Düsseldorf permit up to 50 mg/l of total phosphorous in their municipal sewage systems. This is mostly because only natural human metabolism causes up to 10 mg/l of total phosphorous in wastewater, so, to reduce total phosphorous to 5 mg/l, every domestic house would oblige to have its own WWTP. All this leads to the situation where water companies in Ukraine, instead of modernization their 30-40 years old WWTPs, fine their clients due to the steep requirements. For instance, the municipal water company Khmelnitskvodokanal won the case No 20/4901 against the company “Khmelnitsk plant of experimental production” that discharged into the municipal sewage system in the town of Khmelnitsk its wastewater with 17.42 mg/l phosphates (or 5.68 mg/l as total phosphorous), usual concentration for the EU. Moreover, phosphonates in detergents also contribute to the eutrophication. Another problem is that, due to the lack of trained qualified staff, the amount of total phosphorous determined in different laboratories in the same sample of water may differ by several times.

AbstractMonitoring and regulating discharges of wastewater pollution in water bodies in England is the duty of the Environment Agency. Identification and reporting of pollution events from wastewater treatment plants is the duty of operators. Nevertheless, in 2018, over 400 sewage pollution incidents in England were reported by the public. We present novel pollution event reporting methodologies to identify likely untreated sewage spills from wastewater treatment plants. Daily effluent flow patterns at two wastewater treatment plants were supplemented by operator-reported incidents of untreated sewage discharges. Using machine learning, known spill events served as training data. The probability of correctly classifying a randomly selected pair of ‘spill’ and ‘no-spill’ effluent patterns was above 96%. Of 7160 days without operator-reported spills, 926 were classified as involving a ‘spill’. The analysis also suggests that both wastewater treatment plants made non-compliant discharges of untreated sewage between 2009 and 2020. This proof-of-principle use of machine learning to detect untreated wastewater discharges can help water companies identify malfunctioning treatment plants and inform agencies of unsatisfactory regulatory oversight. Real-time, open access flow and alarm data and analytical approaches will empower professional and citizen scientific scrutiny of the frequency and impact of untreated wastewater discharges, particularly those unreported by operators.

The near and mid-term future of the existing Polish coal-fired power fleet is uncertain. The longer-term operation of unabated coal power is incompatible with climate policy and is economically challenging because of the increasing price of CO2 emission allowances in the EU. The results of the techno-economic analysis presented in this paper indicate that the retrofit of existing coal-fired units, by means of replacing coal-fired boilers with small modular reactors, may be an interesting option for the Polish energy sector. It has been shown that the retrofit can reduce the costs in relation to greenfield investments by as much as 35%. This analysis focuses on the repowering of a 460 MW supercritical coal-fired unit based on the Łagisza power plant design with high temperature small modular nuclear reactors based on the 320 MWth unit design by Kairos Power. The technical analyses did not show any major difficulties in integrating. The economic analyses show that the proposed retrofits can be economically justified, and, in this respect, they are more advantageous than greenfield investments. For the base economic scenario, the difference in NPV (Net Present Value) is more favorable for the retrofit by 556.9 M€ and the discounted payback period for this pathway is 10 years.

The article examines how the normative power, which the EU puts forward as an ideological basis of its actions in the world, manifests itself in the national partnerships for modernization between Russia and EU member states. The authors demonstrate the influence of the EU’s normativity on its approach to modernization as well as the difference in the positions of its member countries. It is concluded that there is no unity in the EU’s approach to democracy, human rights and the rule of law, and the new classification of EU member states, which is based on their readiness to act in accordance with the Union’s concept of normative power, is offered.

Surface Water Contamination

The aim of this paper was to review the literature data regarding the physico-chemical characteristic of plastic pollutants discharged with municipal sewage, the practical possibility of removing microplastic particles from wastewater during different treatment steps in WWTPs and the problem of surface water contamination within them. Microplastics (the size range of 1 nm to < 5 mm), have been recognized as an emerging threat, as well as an ecotoxicological and ecological risk for water ecosystems. Municipal wastewater treatment plants (WWTPs) are mentioned as the main point sources of microplastics in an aquatic environment. Microplastic particles can be effectively removed in the primary treatment zones via solids skimming and sludge settling processes. Different tertiary treatment processes such as: gravity sand filtration, discfilter, air flotation and membrane filtration provide substantial additional removal of microplastics, and the efficiency of wastewater treatment process can be at a removal level of 99.9%. Nevertheless, given the large volumes of effluent constantly discharged to receivers, even tertiary level WWTPs may constitute a considerable source of microplastics in the surface water.

In spite of the fact that negotiations have been going on for years, the chances that Turkey will eventually become a full member of the European Union are slim. At present, a political majority among the EU-member states headed by Germany seems to oppose Turkey entering the EU. In the Netherlands, however, most political parties are still in favour of Turkey's membership. That difference coincides with the difference in the position of Turkish immigrants in German and Dutch societies.

Abstract This study is focused on the changing of areas of water bodies in selected villages of the Pilsen Region (Czechia). We researched several different types of rural settlements and three time horizons with the help of old maps, orthophoto maps and GIS tools. To capture the influence of their location within the urban system, we chose 15 places from four categories (inner suburban area, outside suburban area, rural area, periphery rural area) depending on their distance to the core of the Pilsen agglomeration. There is no significant change in the amount of water bodies between the first reference period (1838-1839) and the second period (1957-1963) in the selected settlements. However, the third period (2013-2015) is characterized by the emergence of a large number of small water bodies - swimming pools and garden ponds. Based on the results of our research we identified the declining importance of public water bodies in some of the settlements. However, we have identified a notable prevalence of garden ponds which have a more positive ecological impact than pools. The proportion of private water bodies (covered and uncovered pools and garden ponds) in the total area of water bodies in the rural settlements in most cases is less than 20%, in the suburban settlements up to 100%. Peripheral settlements have a below-average share of these water bodies. The difference between the number of pools in different settlements is related to the proportion of newly built houses there. Although there are relatively fewer pools in rural settlements, the difference compared to the situation in suburban settlements is not pronounced due to the change in lifestyle in rural areas and the change in functions of some villages to recreational areas. Influence of pools on water consumption is dependent on the individual exchange technology of water in swimming pools. Filling of the pool before the season can overload the capacity of the local water supply.

Critical Aspects

The EU Water Framework Directive requires Member States to assess the quantitative and qualitative status of groundwater bodies and to achieve a good status by 2027. The present study was developed in order to assess the groundwater quantitative status in the Aosta Plain (NW Italy), following the methodology proposed through a guideline defined by the Italian Institute for Environmental Protection and Research (ISPRA), with the aim of supporting local authorities in their periodic assessment of water bodies status. In the study area, during the period 2000-2017, groundwater levels were measured in 213 wells and piezometers. Performing the four tests required by the abovementioned guideline, the quantitative status was assessed on the basis of multi-year groundwater level variations, water balance and the interconnections of groundwater with surface water bodies and groundwaterdependent ecosystems. A good status was assessed for the study area, although some critical aspects emerged from the application of the guideline methodology: the data collected by the monitoring network are not sufficiently robust in terms of sample size, spatial distribution, temporal interval and frequency to fulfill the requirements of the guideline methodology. Therefore, some recommendations to improve the data quality and better address the future assessment of groundwater quantitative status were given.

The article assesses the EU legal system as a unique institutional unit and highlights its features. It deals with the comparative legal aspects of the regulation of the social welfare of migrant workers in the EU and the EAEU. Attention is paid to the study of legislation on social welfare for migrant workers in the EU, as well as the possibility of realizing the experi-ence accumulated within the EAEU. It is emphasized that the use of comparative models con-cerning the social welfare of migrant workers in the EU and the EAEU can be productive, taking into account the analysis of the state and dynamics of the EU's legal policy in its historical development. The authors have analyzed the historical stages reflecting the difference within the EU approaches to the regulation of social welfare relations for migrant workers. The emphasis is on the role of EU administrative institutions, which provide a balancing approach to the key principles and social policy settings, due to the desire to eliminate distortions and possible conflicts between the norms of states. At the same time, EU members have the competence within the existing common standards of financial security obligations to expand the estab-lished standards and this makes the EU's social policy geographically differentiated. It is noted that the allied states, formed on trade and economic grounds, such as the EU and the EAEU, are characterized by an objective desire for a single legal space, with the uni-fication of approaches on the social welfare of migrant workers throughout the Union. Never-theless, in complex interstate unions, it is impossible to abandon the principle of multi-level regulation of social and security relations, and in this sense, the situation in the EU and the EAEU is quite similar. The current state of EU law in terms of regulating the relations under consideration largely preserves national legal regimes, and each of them, through its special legal means, determines a different amount of social rights of migrant workers. In the context of the EAEU, a similar approach should not be considered productive, since it does not contribute to the goals of this interstate association, defined by Article 4 of the Treaty on its creation. Therefore, within the framework of the EAEU, it is advisable to fix as early as possible the uniform standards in the area of social welfare of migrant workers, estab-lishing a relatively narrow range of powers of the member states of the Union.

Abstract Charles Liernur’s Pneumatic Sewage System and the Governing of Soils This article interrogates the epistemological conditions of Charles Liernur’s pneumatic sewage system in order to shed light on the changing relation between soils and Dutch society in the nineteenth century. The first section discusses the relation between hygienism, soil and sewage. The second section unearths how Liernur’s design related to the agricultural chemistry of Justus Liebig. Through the epistemologies and the mediating technologies that are operationalized by hygienists and chemists, soils are made governable. The final section of this article discusses the struggle to commercialise the urban waste collected by Liernur’s system, highlighting the difference between governable and governed soils.
