ABSTRACT
Poland has monitoring activities in rivers, lakes, coastal waters, and the Baltic Sea. The river water-quality surveillance system is composed mainly of conventional monitoring stations. Processes associated with intensive urbanization and the growth of industry has resulted in deterioration of surface water resources, despite the introduction of certain measures for water pollution control. Mathematical modeling of river systems in Poland has become an integral of water resources planning and water-quality management. The prediction of water quality by simulation, mathematical models have been serving as tools in the determination of investment in the construction of wastewater treatment plants. Water resources are unevenly distributed among different parts of the country, water supplies appear inadequate in quality, and demand will grow in many regions. Water-quality improvement programs should be aimed at improvement of treatment methods, implementation of advanced treatment processes, recovery and water reuse in industry, and encouraging the production of biodegradable detergents and pesticides along with use of dry technologies.
