This paper deals with a comparative study on the fluoride removal capacity of readily and cheaply available five kinds of materials-calcium, phosphate, magnesium and magnesium carbonate. Among these materials aluminium phosphate is the most efficient defluoridating agent. 2007

The Veli lake is the smallest among the backwaters of Kerala. The partially treated sewage and the completely untreated industrial effluents are the main sources that brought undesirable changes in the lake.

Acid Mine Drainage (AMD) is recognized as one of the most serious environmental problem in the mining industry. The problem of acid mine drainage has been present since mining activity began thousands of years ago. Mining activity has disrupted the hydrology of mining areas so badly that it is extremely difficult to predict where water would eventually re-emerge.

Geographic Information System (GIS) was utilized to apply a modified DRASTIC method to assess the aquifer vulnerability to pollution of English Bazar Block of Malda District, West Bengal, India. In the western, central and southern parts of the study area the aquifer is prone to contamination. Therefore, in these regions pesticides, which may contain arsenic or arsenic rich groundwater, should not be used in irrigated land or mango orchards. In order to understand the reliability of the aquifer vulnerability, sensitivity analysis was carried out.

The mismanagement of water is one of the most pressing development problems of the day. This research argues that, in some circumstances, an often-neglected form of water management, communal property management, can offer a viable solution to this problem. India has a rich history of traditional water management. Within India, the region of Ladakh was examined as an example of successful communal water management.

A stakeholder workshop for the Tungabhadra basin was organised by the Society for Promoting Participative Eco-system Management (SOPPECOM) and the UNESCO Centre for Water Law, Policy and Science of Dundee University in Scotland in Hospet, India (Karnataka) on 9-10 January 2007.

This study evaluates the presence and extent of toxic pollutants within surface and groundwater resources of the Hindon river catchment. The devastating impacts of this contamination of water resources of the health of those living within the catchment is highlighted.
