India has 18% of the world’s population, 1.15 billion people, but access to only 4% of world’s fresh water resources. In the recent past, the dependency of Indian agriculture on ground water resources has increased upto an enormous extent due to several factors including increased demand of food, erratic behavior of monsoon, developmental pressure of various allied sectors etc. Currently, the a...

background: survey of pollution and evaluation of water quality in rivers with oregon water quality index (owqi) and gis are effective tools for management of the impact of environmental water resources. the information in calculating the wqi of moradbeik river allowed us to take our tests results and make a scientific conclusion about the quality of water. gis can be a powerful tool for develo...

In this paper we investigate the relationship between economic growth and industrial pollution emissions in China using data for 112 major cities between 2001 and 2004. Using disaggregated data we separate FDI inflows from Hong Kong, Macao and Taiwan from those of other foreign economies. We examine four industrial water pollution indicators (wastewater, chemical oxygen demand, hexavalent chrom...

This paper reviews various impacts of urbanization on rivers and streams, which lead to symptoms summarized by the general term “urban stream syndrome”. Growing areas of impervious surfaces cause deterioration of water recipients flowing through urban areas. The symptoms of deterioration usually include altered chemical parameters of water and sediment, accumulation of priority pollutants in aq...

In recent years, worldwide attention has shifted from point source to non-point source (NPS) pollutants, particularly with regard to the pollution of surface and subsurface sources of drinking water. This is due to the widespread occurrence and potential chronic health effects of NPS pollutants. The ubiquitous nature of NPS pollutants poses a complex technical problem. The area1 extent of their...

Abstract The presence of pharmaceutical compounds in the environment has given an unparallel impact on human and environment. Till present day, several methods have been imposed for pollutants’ removal. However, these suffer from some drawbacks which limited their application wastewater treatment. As a new advanced technology, photocatalysis method considered as efficient to eliminate pollutant...

In the 21st Century, Majority of water pollution is caused due to incorrect discharge of waste products into the water bodies. These pollutants can be categorized as dyes, textiles, pesticides and hydrocarbons. This review paper deals with a comprehensive analysis of various methods for degradation of these pollutants in water. Due to the efficient mineralization of organic compounds; advanced ...

From the first awareness of agricultural sources of water pollution in the US in the 1960s, we finally see in the 1990s a commitment at the national level for agricultural non-point source (NPS) pollution control. This has been occasioned by a growing awareness that, with point sources of some pollutants largely controlled by waste-water treatment, greater attention must be paid to NPS pollutio...

Wastewater is the spent or used water containing dissolved or suspended solids such as pollutants and microbes, including nutrients. The wastewater discharged into the water bodies are hazardous to environment and cause various health problems in human beings. Eutrophication is one such major environmental problem caused due to the discharge of nutrient rich wastewater into the nearby water bod...

Organic pollution is a significant challenge in environmental protection, especially the discharge of refractory organic pollutants chemical production and domestic use. The biological treatment method traditional sewage plants cannot degrade such pollutants, which leads to continuous transfer these into water environment. Therefore, it necessary study clean efficient advanced technologies poll...
