Abstract: Kysil M.I., Vronska N.Y. (supervisor). Environmental assessment of the city of Lviv. Master’s Thesis - Lviv Polytechnic National University, Lviv, 2024 Extended Abstract The study focuses on the environmental assessment of the city of Lviv in the context of modern urban challenges and ecological risks. The primary goal of this work is to analyze the condition of key environmental components and to develop strategies for enhancing its ecological sustainability. The study includes a comprehensive analysis of air quality, water resources, wastewater management systems, green spaces, waste management practices, and other critical aspects of the urban environment. The environmental situation in Lviv is characterized by significant challenges, driven by the slow modernization of industrial enterprises, inefficient transportation infrastructure, high urban density, and insufficient ecological awareness among the population. The analysis revealed that the main sources of air pollution are mobile sources (96% of emissions) and thermal energy enterprises. The situation is further aggravated by inadequate fuel quality control and the lack of modern transportation solutions. The analysis of water resources showed that Lviv heavily relies on groundwater (99% of its water supply). However, the condition of the water supply and sewage infrastructure requires modernization. Key issues include high water loss rates, pollution of surface water bodies, and inefficiencies in wastewater treatment. The city’s water bodies, particularly the Poltva River, remain ecologically stressed zones, posing international environmental risks. The study also addresses waste management issues, including municipal solid waste (MSW). The development of organic waste composting systems is highlighted as a promising approach to reducing landfill burdens and fostering the principles of a circular economy. Proposed strategies include enhancing environmental monitoring, modernizing the transportation system, creating bypass routes for transit traffic, expanding green spaces, and increasing public ecological awareness. These measures aim to ensure Lviv’s sustainable development and improve the quality of life for its residents. 8 Object of the study: The environmental condition of the city of Lviv, including air quality, water resources, biodiversity, and soil conditions. Subject of the study: Key ecological risks related to the city’s water resources, methods for their assessment, and opportunities to mitigate them, particularly through the adoption of sustainable technologies in water supply, wastewater management, and sewage treatment. Objective of the study: To conduct a comprehensive analysis of Lviv’s environmental condition, identify key problems, and explore solutions using modern methods of environmental monitoring. Research tasks: 1. To assess the quality of air, water resources, soil, and biodiversity in the city. 2. To analyze modern methods of water purification and waste management. 3. To identify ecological risks associated with the urban environment. The study employs modern analytical methods, including environmental monitoring, modeling, cluster analysis, and comparisons with global practices. The research highlights the main ecological challenges facing Lviv and proposes measures to reduce pollution levels and enhance environmental safety. Particular attention is given to the analysis of water resource conditions and the prospects for implementing sustainable waste management technologies. The results of the study can be used to develop local environmental strategies, improve environmental monitoring, and enhance the efficiency of natural resource management. Keywords: environmental assessment, air quality, water resources, urban environment, sustainable development, waste management, biodiversity.
