The fluoride contamination study has been carried out in ground waters of Khanapur, Bailhongal and Saundatti taluks of Malaprabha sub basin, Belgaum district, Karnataka. 21 samples were collected during the pre-monsoon and post-monsoon season of 1999.

The present study of Bichlari Nala, flowing through Banihal and Ramban (J&K State) has been selected for the potential of surface water resource and its quality has been evaluated thoroughly to generate baseline information.

The quality of water in four streams of Cauvery River in Mandya
District, where many small scale sugar and brewery distilleries are located, was analysed. Sampling was carried out from four streams designated as station 1 (upstream of effluent discharge point), station 2 (effluent discharge point) and station 3 (downstream of effluent discharge) station 4 (fresh water

Total heterotropic plate count (HPC), fecal coliform (FC), Escherichia coli (EC), Salmonella and Shigella were estimated in water samples collected from 21 bore wells and 15 hand pumps in and around Kanpur district, during early and post monsoon which revealed the unsanitary condition of water sources.

Outflow from agricultural fields carries diffuse pollutants like nutrients, pesticides, herbicides etc and transports the pollutants into the nearby streams. It is a matter of serious concern for water managers and environmental researchers.

Effects of industrial effluents on germination, growth, protein content and metal accumulation patterns in Hibiscus esculentus L. were studied. Effluent from two factories in the industrial belt of Cochin, Kerala were used to soak the seeds for germination and to irrigate the seedlings in the field after physico-chemical analysis.

The histopathological studies are useful in evaluating the pollution potential of toxicants since trace levels of chemicals do not bring about animal mortality over a given period and are capable of inducing considerable damage to organ.

The trace metal levels were studied in soil and water of Tipong, Tirap and Tikak Collieries of Makum Coal Field, Tinsukia, Assam. The toxic trace metals were analyzed using Atomic Absorption Spectrophotometer (AAS). On the basis of the results obtained, it is clear that continuous mining operations have left permanent scars in the coalfield environmental scenario to a large extent.
