The results of studies of sea and river waters, soils of the territory adjacent to the Vanino transport and industrial hub are presented. Iron, manganese, copper and zinc have been identified as common priority pollutants of sea and river water. The quality of river waters of the Toki and Aya rivers, estimated by 14 hydrochemical indicators, is classified as "polluted". Local areas of peat-bog soil and brown soils belonging to the Toki river catchment area were identified as background areas in the studied territory.

The present research is related to one of the basic component of the environment – waters with study area the Ogosta river catchment. It is based on the investigation of water samples collected during field research in the river monitoring area and laboratory analysis. The research is focused on the state of the pollution and quality of the water. The results can be used in the processes of environmental optimization and realization of the strategies for sustainable development in the region.

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

The evaluation concerns selected indices of oxygen regime and of basic physical and chemical indices: BSK5, N-NO3-, N-NH4+, P-PO43-, the total phosphorus and dissolved matters. A particular attention is paid to a comparison of average levels for the whole observed period and for the last five years. The indices of quality are selected to register mainly local sources of pollution which most influence the quality of water in the Ohře river and in its affluents.

Intensification of economic activities (construction of terminal for liquefied hydrocarbon gas, coal and alumina trans-shipment) in the Khabarovsk Kray Vanino Rayon made it necessary to determine the dissolved substances background concentrations in the river waters. The 2015 observations in the Vanino Rayon “Tumninskiy” nature reserve enabled to establish spatial variability of the substances content in the small rivers’ water during the summer-fall low water period. According to the 1966–1982 Rosgidromet data the characteristic of the Tumnin River water chemical composition has been given. Differences in the dissolved substances content in the natural reserve rivers’ waters caused by the territory natural/climatic special features have been revealed. The mineralization low values (<55 mg/dm3) and hydro/carbonate/calcium composition of the Tumnin River and its left-side tributaries’ waters have been shown. The sodium ions and chloride ions higher concentrations (at the average 2.0 mg/dm3 higher) and mineralization values (10 mg/dm3 higher) have been registered in the Tatar Strait coast mainland part rivers’ waters outside the zone of the high/low tides flows influence. Higher concentrations of aluminum, iron, manganese and organic matter have been found in the Tumnin River basin small rivers’ waters draining wetlands in the catchment lower parts. Nitrates nitrogen maximal concentrations have been notices in the Tatar Strait coast continental part rivers’ waters whose catchments had been affected by forest fires. The higher concentrations of silicon and mineral phosphorous have been shown in the small rivers’ waters draining deposits of volcano origin. Dissolved microelements concentrations in the conditions of the river waters low mineralization are comparatively low.

Abstract There is a dearth of information in the literature concerning water quality changes between the headpond and the point where river water emerges from a hydroelectric station. This type of information is required in order to produce continuous water quality models in rivers where there are hydro developments. This project concerns a study conducted to determine the nature of water quality changes as St. John River water passes through the Mactaquac Hydroelectric Dam. Samples were collected from points immediately above and immediately below the Dam in each season thereby covering a range of temperature and flow. The samples were analyzed for temperature, biochemical oxygen demand, organic carbon, dissolved oxygen, pH, conductance, alkalinity, hardnesss, tannin and lignin, phosphate, total kjedlahl nitrogen, iron, manganese, copper and zinc. An analysis of the results revealed that the water quality changes were erratic. On some occasions there were slight increases in parameter values between the upstream and downstream stations and sometimes there were slight decreases. It is concluded that, for the measured parameters, there is a negligible change in the quality of the river water as it passes through Mactaquac Dam.

Four central rivers of Bangladesh were selected for this research. The name of the rivers is Buriganga, Dhaleshwari, Shitalakshya and Meghna. The Electrical Conductivity (EC), pH, Total Dissolved Solid (TDS), and Salinity of the four river waters were evaluated. The EC values of the water of the Buriganga, Dhaleshwari, Shitalakshya and Meghna rivers were found to be 366.0, 299.2, 290.4 and 130.8 µS/cm respectively. Similarly, the pH values of 7.67, 7.38, 7.30 and 7.18 were found for the river waters of the Buriganga, Dhaleshwari, Shitalakshya and Meghna respectively. The EC and pH values were found higher for the Buriganga river water than that of the other three river waters. The TDS and salinity of the Buriganga river water were found 180 mg/l and 0.72% respectively. On the other hand, the TDS and salinity of the Meghna river water was found lower compared to the other three rivers. From this research, this is clear that the quality of the Meghna river water is much better than the river waters of the Buriganga, Dhaleshwari, and Shitalakshya. The quality of the Buriganga river water was found inferior. Dhaka city, the capital of Bangladesh, stands on the bank of the Buriganga river, and as a result a large number of unban waste goes directly to the river Buriganga. As a result, the water of Buriganga became polluted. This investigation proved that the Meghna river water quality is still much better and suitable for many applications.

Data of the Federal Information Fund for Social Hygiene Monitoring conducted on the basis of the Federal Center for Hygiene and Epidemiology of Rospotrebnadzor have been analyzed to assess environmental risks, as well as to develop environmental safety system as a factor for sustainable development of the territory in the regions of the Russian Federation. Atmospheric air pollution in Russian regions was evaluated by content of priority pollutants. Ranking of Russian regions according to the quality of drinking water supply was carried out. The possibility of using Federal Information Fund for Social Hygiene Monitoring as an integral part of the model for optimizing the social and environmental conditions of populated areas is estimated.
