Influence of Ecological Conditions of Water Sources on Water Supply of a Megalopolis

SUMMARY

In theory the improvement of conditions of surface sources of water supply is an effective method of enhancement of potable water quality. However, even if there are possibilities to realize nature-conservative measures they have long-term character. In practice the most realizable methods are correction of water quality at water treatment stations’ water intakes changing the hydrologic conditions and operative control over water treatment at water treatment stations. The application of classical technique of water treatment with coagulation and clarification in complex with ozone sorption and ultrafiltration makes it possible to ensure the necessary degree of water treatment and its compliance with the perspective normative requirements regardless of conditions of a water supply source.

Estimation of biological hazard of organic xenobiotics
in water supply sources

Summary

Identification of pollutants, estimation of their concentration in water and biological hazard are important practical tasks in the assessment of water quality in the Moscow drinking water sources. In estimating the pollution rate of a water body it is required to draw out a xenobiotics profile, i. e. the complex of bioactive species of all the xenobiotics present in water. Among xenobiotics the compounds of medical origin were defined alongside with compounds with pharmacological activity, however not used in medicine («quasidrugs»). The technique of determining biological activity profile with the help of a special search and design information system has been developed. The first part of the system is based on the Russian and international regulatory documents; lists of especially hazardous substances; guides on separate toxic substances; journals or data bases compiled by international and national organizations. The second part of the system is represented by the technique of prognosticating biological activity on the basis of analyzing its relationships with the chemical structure of a substance. This method has been implemented in PASS software with teaching selection containing the information on more than 250,000 pharmaceuticals and toxicants. Xenobiotic profile can be reflected on ecotoxicological maps. The results of studies give the start to sequential practical actions from compiling a xenobiotic profile of a project to developing efficient water treatment technologies that will provide for reducing the concentration of xenobiotics inclu­ding ones with pharmacological activity to the maximum permissible level.

Assessment of the state of water supply sources under the conditions
of anthropogenic eutrophication of water reservoirs

Summary

Deterioration of the water quality in water supply sources and amplification of water treatment technologies have been typical pheno­mena under the conditions of anthropogenic eutrophication of water reservoirs. The results of water quality monitoring in the Kuibyshev water reservoir under normal and abnormal weather conditions are presented. The observations were carried out both at fixed and mobile stations with the use of traditional and automated measuring instruments. It was stated that phosphate concentrations in water influenced the rate and duration of algae growth (water bloom). On the basis of the observations in an abnormally hot year the prediction of the ecological state of the water reservoir under the conditions of global warming in the Lower Volga watershed is made. It is shown that under the conditions of excess nutrient load and global temperature increase the state of the Kuibyshev water reservoir as a water supply source will deteriorate. The measures are recommended that will provide for reducing the nutrient load in the water reservoir including the development and introduction of regional standards with account for the natural specifics of the given water supply source.

Surface runoff of Samara: effect of the seasonal factors

Summary

Surface runoff is still one of the main sources of pollutants discharged into water bodies. By the example of the storm sewer system of Samara urban district the detailed qualitative and quantitative characteristics of the discharged wastewater are considered. The storm sewer of Samara receives surface runoff and drainage water from the urban territory and territory of industrial enterprises, clean surface runoff, drainage flow from heat distribution networks and process effluent generated in the process of the network maintenance. The data is presented on the assessment of the seasonal variation of the effluent quality. A representative set of indicators for monitoring purposes and diagnostics of the state of the wastewater disposal system is presented. The representative diagnostic set includes the following indicators: рН, BODfull, suspended solids, dry residue, ammonium, nitrates, nitrites, copper, aluminium, oil products. The results of the studies of interaction between the raw water quality coming to the pumping filtration station of Samara and characteristics of the surface runoff discharged upstream the same water body are cited. It is shown that the water source turbidity and color are related to certain qualitative parameters of the surface runoff. The level of this interaction is estimated; calculation dependencies are proposed. The need for the further implementation of the municipal program of the storm sewer system of Samara urban district is substantiated.
