Identification of organic pollutants of water in sources of water supply (using the example of the Astrakhan region)

Abstract

In today’s diverse world, one of the most urgent tasks is environmental protection, rational use and reproduction of natural resources, conservation of biological diversity. The problem of clean water is one of the most important places in the solution of this problem because surface waters are the most sensitive natural environment link. Without careful monitoring of the state indicated by the latter, it is impossible to prevent the occurrence of adverse environmental situations, maintain the health of the nation and ensure the quality of life. Based on the results of the analysis of indicators of the quality of the water source, the required volumes of water for the consumer and the requirements of the consumer for the produced water, a decision is made on the technology for purifying the required water. Special climatic conditions (sharply continental climate, high summer temperatures, low water levels, etc.) negatively affect the quality indicators of the water source. The article presents the results of a study of surface water by microbiological indicators and phytoplankton. Water was investigated in the area of the channel-type surface water intake structure located in the Astrakhan region on the Volga. It is revealed that the river belongs to the category of dirty. Moreover, there is a positive trend in the development of this process. Applied water treatment technologies are not able to fulfill the tasks to ensure a safe drinking regime. It is known that chlorination of water during water treatment does not affect the removal of metabolites secreted by massively developing species of cyanobacteria (blue-green algae). The recommendations for improving water treatment facilities are made.
