The temporal and spatial distribution of trace metals in the surface sediments of Chitrapuzha river were studied.

The productivity status of 3 aquatic systems situated near Nirup synchrome dye industry, leather industry and Kakatiya University campus were analysed during 2002-03.

An attempt has been made in this study to assess the quality of ground water at the suburban area near Madurai airport by studying the physicochemical parameters and few metal ions of the water samples for a period of 1 year. It has been found that the quality of ground water is suitable for the domestic and general purpose. But they cannot be used for drinking purpose.

Surface and groundwater pollution in the mining and industrial area is a growing concern. Jharia Coalfield is one of the biggest coalfield and highly industrialized area in India. A study was undertaken in some of the coal mining and industrial areas in this coalfield to assess the quality of surface and groundwater.

The quality of ground water samples collected from 7 representatives tubewells in rural areas around Angul-Talcher industrial zone, Orissa was assessed in the rainy, winter and summer from July 2001 to June 2003. A total of 20 physico-chemical characteristics were analysed. Some parameters were found within and some parameters beyond the desirable limit for drinking purpose.
