Для отдельных муниципальных территорий, расположенных в бассейне оз. Ханка, проведена комплексная оценка водопользования, в том числе точечных сбросов загрязняющих веществ предприятиями-водопользователями. Описан состав этих сбросов с указанием характерных для каждой территории и производственной отрасли загрязняющих веществ. Установлены водотоки с наибольшими объемами сбросов. Показано, что самыми загрязненными на протяжении многих лет являются небольшие реки с низкой самоочищающей способностью. Анализируются современные и ретроспективные особенности качественного состава речных вод бассейна в целом, приводится оценка динамики качества отдельных водотоков по удельным комбинаторным индексам загрязнения вод (УКИЗВ). At the level of municipal territories a comprehensive assessment of water use in the Khanka Lake basin, including point sources of polluting substances discharge by water use industrial enterprises, has been conducted. The composition of sewage with an indication of distinctive pollutants for every territory and industrial sector is analyzed. Watercourses for which the volumes of pollutants discharges are the largest are identified. The most polluted of them over the many years are shown to be the small rivers with low self-cleaning capability. The modern and retrospective features of the river water quality in the Khanka Lake basin are analyzed, and the dynamics of the quality of some watercourses using calculated pollution indices is estimated.

Method Approach

The industrial sector is one of the important sector in supporting the development of a region. Utilization of land around the river that is used for industrial activities will affect the quality of river water. The river can be polluted by waste personinating from industries that operating around the river. The catchment area that used for industry, agriculture, urban development, and the use of land for making roads (gravel or footpaths) can affect the flow of surface water and sediments that it brings to the river. Waste generated from industrial activities can pollute rivers which are a source of water for daily needs and affect the development of biota in them. This can affect river water quality

Bacterial Source Tracking

This study is only the second to use DNA fingerprinting technology in Maryland to identify fecal coliform sources in order to guide the implementation of water pollution control practices in a watershed with bacterial impairment. By combining the use of digital air photos and GPS with GIS, fieldwork is planned and conducted more efficiently because sample sites can be selected that accurately represent the physical environment of the study area. We can also return to the field and find our sample sites or locate new ones, even in the remotest part of the study area. It is also possible to more accurately map the data directly in the context of its physical environment, greatly increasing the quality of analysis. The integration of DNA fingerprinting techniques with GIS shows great promise for extending our capabilities to identify the controls on water quality and point sources of waterborne health hazards.

Through the analysis on the data of monitoring water quality of typical reservoirs in Liaoning province, the major reservoirs in the province are in the state of mesotrophication or even eutrophication. The main pollutants are DO-consumption organic pollutants such as ammonia nitrogen and phosphorus. Despite years of special treatment, quality indexes about such nutrients are still high and they severely restrict improvement of the water quality. On the basis of the primary research, this article analyses the main reason for production of phosphorus and nitrogen, estimates the annual load of non point sources pollution and provides a basis for controlling of the pollution.

The Dragon lake diversion channel (DLDC) is the only river that recharges Dragon Lake, an artificial lake in China. This paper examines the main factors influencing water quality by investigating point source and non-point source pollutants along the main route. Based on the complicated system of rivers and desilting basins, a three-dimensional water quality model using environmental fluid dynamics code (EFDC) was developed. The model of DLDC was calibrated and verified using observed data. The error ranges of river water level, total phosphorus, total nitrogen and chemical oxygen demand were within 5%, 10%, 16% and 20%, respectively, all of which meet the precision requirement. The model was employed to predict the concentrations of pollutants in the main stream under current pollution loads within a year and a flood lasting for 24 hours. The results revealed that the main pollution sources that influence the water quality of waterways were the point sources followed by the non-point pollution sources. Water quality improved when large water quantities were delivered and this trend can be described as dilution. The water quality of the Dongfeng main channel meets the requirement; however, the water quality of the Dongfeng River is somewhat poor, and the water quality of the Wei River is seriously contaminated. To address these problems, we suggest that the Dongfeng River and Wei River adopt a culvert under its riverbeds.

In this work we performed a complex geographical analysis of the Bovan Lake basin, Serbia, as well as an analysis of the physical, chemical and biological parameters of water reservoir during a one-year period. The basic sanitary characteristics and physical, chemical and biological parameters, necessary for understanding locality conditions, were studied, and the saprobity index, class of quality, index O/H, degree of saprobity, degree of trophicity and category based on the phosphatase activity index (PAI), were determined. Our results classify the ecosystem as polytrophic. The degree of saprobity is oligosaprobic - beta mesosaprobic, with a catarobic degree in winter, classifying the water as III - IV class of quality. Due to the presence of organic residues, a domination of heterotrophic bacteria in comparison to oligotrophic bacteria is evident. The ability of autopurification is weak. The results indicate the need for continual monitoring of the water quality and environmental protection of Bovan Lake.
