Onishchenko G. G.

Hygienic evaluation of the provision of the population of the Russian Federation with drinking water and measures for its improvements

In accordance with the sanitary-and-epidemiological requirements, drinking water should be epidemiologically, radiationally, and chemically safe and have good organoleptic properties. In 2007 versus 2006, the situation associated with the state of both underground and surface sources of centralized drinking water supply and the quality of water in the areas of hydraulic works substantially unchanged and continues to remain poor. In 2007, the proportion of water pipes from the underground sources unconformable to the sanitary regulations and standards was 20%, including those due to the absence of sanitary control areas (13.1%), the required complex of waste disposal plants (6.1%), or sterilizing units (2.6%). After water preparation, the quality of water continues to remain poor in terms of sanitary and chemical parameters. In 2007 in the Russian Federation, 17.5 and 5.8% of water samples from the water-supply network were unconformable to the hygienic requirements in sanitary-and-chemical and microbiological parameters, respectively. As for rural water supply, in 2007 in the Russian Federation, rural areas exploited 59362 water pipes, i.e. 82.5% of the water pipers in Russia as a whole. The proportion of water pipes in the rural areas, which were unconformable to the sanitary regulations and standards, was 21.2% in 2007, including those due to the absence of sanitary control areas (13.7%), a required complex of waste disposal plants (6.8%), or sterilizing units (3.3%).
