Session 4. Water quality in natural reservoirs

High-quality water is necessary for preserving public health, biodiversity, environment’s aesthetic and recreational potential, food production and manufacturing. The importance of anthropogenic impact on chemical compound of water in natural reservoirs is increasingly comparable with natural geochemical and biologic processes. Transformation of catchment basins, transboundary flows, direct industrial and communal discharges, unorganised drainages lead to disruption of water ecosystems, eutrophication, acidulation, appearance of toxic elements and substances in water environment, resulting in lower water quality. Climatic variations also contribute to changing hydro-chemical regime by changing hydrological cycles, emergence of drought or excessive rainfall periods.

Maintaining high quality of water in natural reservoirs is one of the crucial conditions for sustaining life on the planet, and, thus, becomes a particularly acute present-day problem. Major related issues include the following: controlling water quality under the existing anthropogenic load and global warming; biogenic pollution of agricultural lands and water reserves’ eutrophication; acid rains, and water acidulation; circulation of toxic elements in ground waters and self-purification processes; environmental consequences of major rivers, lakes, and transboundary waterways pollution; methodology and  techniques for biological assessment of water quality; recovery of water quality and hydroecosystems following reduced pollution.
