Background and Objective: With the industrialization of communities, population increase and use of surface water, river pollution has been increased by agricultural, industrial pollutants and urban wastewater. Therefore, investigation of river pollution for regional and environmental planning is of great importance. To evaluate surface water pollution, a number of surface water quality indices...
twenty water samples from a river system in southern caspian sea basin werecollected and analyzed for physicochemical parameters and metals (cu, zn, as, cd, pb, ni andmn). in order to evaluate the risk potential of metal pollution in river water, use of two indicesnamely heavy metal pollution index (hpi) and contamination index (cd) accompanied by clusteranalysis was taken in to consideration. ...
Wise and sustainable uses of water resources are essential for an effective river-basin-management planning. Recent management strategy further addresses the fact that quantity and quality of water are closely interrelated, and both must be considered simultaneously for all water resources and water quality management practices. The aim of this paper is to explore the impacts of water resources...
Aquatic environmental deterioration is becoming a serious problem due to rapid urbanization and economic development, particularly in developing countries. As two important components of the aquatic environment, water quality and sediment pollution are widely considered to be concerns; however, they are considered separately in most cases. The relationship between water quality and sediment pol...
Water of River Kosi in stretch of 35 Kms at Rampur was studied for pollution by determining various water quality parameters, for all three seasons viz. winter, summer and rainy season. The river is subjected to severe domestic and industrial pollution at Kashipur (U.A). This polluted water is carried down stream to Rampur (U.P.). The pH range is 7.3 to 7.9.The organic pollution is mild as indi...
The aim of this study was to establish microbial and heavy metal pollution of the Sava River at three locations close to industry and urban areas (Šabac, Obrenovac, Beograd) in Serbia. Heavy metal analysis included Cu, Zn, Pb, and Cd in the river water and sediment samples. Using the microbiological analysis we tried to establish the effectiveness of total coliforms, faecal coliforms and Escher...
In this paper, we to assess the level of pollution in the Akagera Transboundary River. The followings parameters namely NH4-N, NO3-N, PO4-P, Total Dissolved Solids (TDS), conductivity, pH, Temperature, and Turbidity were identified and quantified. Sampling was conducted a monthly basis from March 2008 to February 2009 at eleven sampling points on the Akagera River system. The landuse and land f...
abstract shahdadroud river is one of the most important rivers in kerman province that during previous years has been threatened by drought and anthropogenic pollution. this river supplies some parts of drinking water of kerman city and some vicinity villages. the main objective of the present study is consideration of pollution situation of the river; for this purpose, limnological and biologi...
The acceleration of urbanization and rapid development of economy led to making surface water pollution problem becoming more critical. Water treatment technologies can be generally classified as insitu or ex-situ. In this paper, a comprehensive review describing the latest surface water remediation developments and technologies that can be suitable for in-situ applications. The review covers t...
