Water Strategy

Water resources protection and rehabilitation to the ecologicallly favorable living condition is one of the main tasks of Water Strategy of the RF till 2020. This task cannot be considered fulfilled. This article analyses the reasons of the situation. Several broblems are discussed: insufficient scientific support of the natural waters quality assessment methods, state of the quality management (regulating) system, lack of the advanced and adequate monitoring system, and lack of funding for the purposes of water protection. It has been shown that scientific/methodological basis for natural waters quality assessment and management focused on the MPC system and the discharges statistics according to the 2-TP (vodkhoz) pattern is obsolete and out-dated. No monitoring of micro-pollutants, zenobiotic first of all, is done. Practically, there is no monitoring of bottom sediments. Thechnology of hydro/chemical information processing is not developed. Any requirements to the disposed water quality should take into account the background concentrations different for water bodies located in different physical/geographic and climatic zones. The order of procedure for transition from the current discharge regulation system on the basis of NDS to the system based on NDT is not worked out. There are no norms of the pollutants content in bottom sediments. It has been proposed to apply information techniques for assessment of the xenobiotic pollution on the basis of the biological activity forecast for PASS and GUSAR compounds. All units of the water sector are to use computer information/calculating systems provided with the advanced model of water basins and their sections in order to change radically the situation with water sector funding. It seems that one of the possible ways of the water quality regulating problems is the transition to the risk-oriented approach which is actively used in the legislative regulation systems of the developed countries.

The Impact

Methodological approach to the water quality and ecosystem health from the ecological paradigm position has been vindicated. Critical analysis of the currently existing methods of water quality assessment has been performed. It has been shown that biological criteria of the ecosystems’ status diagnostics (in-situ) based on studying of laws of aquatic organisms and communities organization levels variability adequately reflect water quality and ecosystem health. New methodical solutions on hydro/chemical information compression to the unified indicator of the impact doze and vindication of informative biological water quality assessment criteria are depicted. Results of practical testing of the developed methods on a number of water bodies of Russia are presented. The methods are based on revealing of the cause-effect relations that are developed on the basis of doze-effect dependencies between the water quality chemical composition integral indicator and fish physiological status indicators.

Purpose: to assess the quality of water in water bodies of the Volga-Akhtuba floodplain from an ecological viewpoint, taking into account the modern regulatory framework in the field of environmental protection. Materials and Methods. To assess the quality of natural waters from an ecological viewpoint, a complex indicator calculated by basic analyte markers that characterize typical negative impacts was used. The following hydrochemical indicators were taken as analyte markers: pH, mineralization (dry residue), suspended solids of natural origin, total iron, total manganese, ammonium (N), nitrites (N), nitrates (N), phosphates (PO4), chemical oxygen demand (COD). Results. The ecological state of water bodies was determined by hydro-chemical indicators of surface waters and bottom sediments using the example of such representative objects as water bodies on the territory of the Volga-Akhtuba floodplain: lakes Peschanoe, Varyuzhka, Zhestkovo, erik Chayka, lakes Beshenoe, Chubatoe, Yamy, erik Shumrovatyy, lake Shirokogorloe. In accordance with the provisions of GOST R 58556-2019 “Assessment of water quality in water bodies from an ecological point of view”, the quality of water from an ecological viewpoint, the degree of quality disturbance and changes in the state of aquatic ecosystems under anthropogenic load have been determined. Conclusions. Petroleum products have been recorded in the water bodies of the Volga-Akhtuba floodplain (lake Varyuzhka, erik Shumrovatyy). The analysis of hydrochemical indicators of water quality and bottom sediments shows that currently the overall level of pollution of the considered water bodies does not reach critical levels of permissible values.

Reference Manual

The first edition of Bioanalytical Tools in Water Quality Assessment was released in 2012. The field has exploded since and the second edition updates and reviews the application of bioanalytical tools for water quality assessment including surveillance monitoring. The book focuses on applications to water quality assessment ranging from wastewater to drinking water, including recycled water, as well as treatment processes and advanced water treatment. Emerging applications for other environmental matrices are also included. Bioanalytical Tools in Water Quality Assessment, Second Edition, not only demonstrates applications but also fills in the background knowledge in toxicology/ecotoxicology needed to appreciate these applications. Each chapter summarises fundamental material in a targeted way so that information can be applied to better understand the use of bioanalytical tools in water quality assessment. The book can be used by lecturers teaching academic and professional courses and also by risk assessors, regulators, experts, consultants, researchers and managers working in the water sector. It can also be a reference manual for environmental engineers, analytical chemists and toxicologists. ISBN: 9781789061970 (Paperback) ISBN: 9781789061987 (eBook)
