The improvement of ecological monitoring for water bodies of the middle course of Syrdarya river
Abstract
The article is devoted to research of the ecological state of water bodies used by the population for drinking water usage. It is established that in areas of discharges of insufficiently treated industrial waste waters located in the river basin enterprises water quality does not meet the requirements on the studied parameters. To improve environmental monitoring and development of measures on protection of water objects in the basin of the middle course of the Syrdarya river carried out medium-term forecast of influence of the enterprise's waste water on water quality of the river Chirchik. The results of the forecast showed that by 2020, the standards of water quality in Chirchik river may be impaired for ammonia, nitrites, nitrates, petroleum products, and sanitary-indicative microorganisms. The magnitude of ammonia will exceed the installed regulations 2.9; nitrite and 9.3; nitrate and 3.2 and petroleum products – by 3.4 times, respectively. For the settlement period of the forecast should also expect increased levels of bacterial pollution of water by index lactosonegative Escherichia coli, Escherichia coli and enterococci. Based on the research developed the methodical recommendations on monitoring of water objects in the basin of the middle course of the Syrdarya river, to the Ministry of Health of the Republic of Uzbekistan, the practical application of which will prevent further pollution of water bodies used for potable and cultural-domestic water use of the population.
