Abstract
The article gives an environmental assessment of the effectiveness of drinking water purification at the water supply facilities of the Utility Company «ZhytomyrVodokanal» and found that traditional water treatment technologies such as one-stage and two-stage purification schemes for drinking water are technically outdated, as they do not provide complete cleaning of surface water from the pollutants such as manganese, phytoplankton and permanaganate oxidation, as well as they are completely ineffective in the preparation of drinking water during the warm period of the year (from the middle of spring to mid-autumn), because many residual concentrations of chloroform compounds, permanganate oxidation, manganese, residual aluminum still remain present in "drinking water" in excess of regulatory concentrations. Existing traditional technologies can only be used if they are refined, with due consideration for the permanent deterioration of the surface water quality in the reservoir «Vidsichne». It has been established that such quality, especially in the summer, according to same indicators didn’t measure up SanPiNu regulations 4630-88 (Sanitary rules and norms of surface waters protection from pollution). Thus applies to the indicators of organic pollution, such as biological oxygen consumption and chemical oxygen consumption, toxicological indices – total iron and manganese, and organoleptic index – turbidity. In accordance with the classification of surface water quality – sources of centralized drinking water supply DSTU 4808:2007 «Sources of centralized drinking water supply. Hygienic and environmental requirements for quality and selection rules», surface water quality with established deviation from the norm refers to class 3-4. The available amount of phytoplankton in the reservoir also relates the quality of water to grade 4, which in turn complicates the process of water purification according to traditional technologies.
