Water is one of the major factors of environment on what health and sanitary living conditions of the population appreciably depend. Increase of reliability and quality of water supply of the population potable water is one of prime social problems. Maintenance with potable water of the population in Krasnodar region is made priority through the centralized systems of water supply.

In Krasnodar region for economic-drinking water supply mainly are used deep-well waters. Except underground waters, as a water supply source, the rivers Kuban and Urup are used, that makes 11 % from all quantity of submitted water to the consumer.

Fresh underground waters of a southern part of the Azovo-Kuban artesian pool differ remarkable drinking qualities. By results of researches of water quality of pool as a whole, the highest indicators of discrepancy have territories of northern zone of the region where water on natural qualities doesn’t meet the requirements of the sanitary legislation and can’t be applied to drinking needs without corresponding water preparation. Activators of pathogenic, conditional-pathogenic flora and parasitic diseases in the given water sources are not revealed. On radiological researches all tests answer hygienic specifications.

Quality of water in the river Kuban according to long-term supervision doesn’t correspond to specifications. The river Urup as the water supply source is unstable and doesn’t guarantee constant quality of water because of seasonal fluctuations of a water level and uniform water selection. The basic sources of pollution of the rivers Urup and Kuban are:

• Transboundary carrying over of polluting substances from the sources located in upper courses of the rivers and their inflows (organic substances, hydrocarbons, zinc, copper);
• Substandard work of municipal treatment facilities of the water drain, inefficient work of local treatment facilities of the water drain of various objects;
• Storm drains from settlement territories and the agricultural objects located in coastal zones.

At the Black Sea coast of Krasnodar region the basic source of economic-drinking water supply are the underground waters dated to channel adjournment of river valleys, running into Black sea. A distinctive feature of formation of underground waters in coast valleys – close interrelation of their accumulation from dropping out deposits that leads to deficiency of water in absence of rains and to microbic pollution of water sources.

Thus, the most reliable in the sanitary relation are fresh underground waters of the Azovo-Kuban artesian pool.

With a view of development and modernization of water supply systems in region, work on program realization «Maintenance of the population of Krasnodar region with potable water for 1999-2010» is spent, in which questions of monitoring of water supply sources quality are reflected.
