The occurrences of iron and manganese, in the present study was carried out from Manar dam (Nanded district, Maharashtra). Two sampling stations were selected for present study.

A three-dimensional mathematical model to simulate regional groundwater flow was used in the coastal area of Kanyakumari district in South Tamil Nadu. The study area is characterized by heavy rainfall, less extraction of groundwater for agricultural, industrial and drinking water supplies.

The study on physico chemical characteristics of estuary (Rajakkamangalam) water samples were collected in four sampling stations were studied in 2001.

To find an approach to underground drinking water management through statistical regression analysis of various water quality parameters, the correlation analysis of eight data point of water of different IM2 handpumps at Moradabad was performed.

This paper investigates the adsorption of arsenic, As (III) and As (V) from water onto activated alumina (AA) which was used as an adsorbent in batch and column adsorption experiments and critically analyses the effect of various parameters, such as contact time, pH of water, adsorbent dose, and inlet arsenic concentration to find out removal of arsenic by adsorption on AA.

Pollution of rivers first affects its physico-chemical quality; later on it systematically destroys the community disrupting the delicate food web. To assess the level of pollution of main rivers of Punjab, Sutlej and Beas, water quality indices have been calculated with the help of sixteen water quality physico-chemical parameters using WHO/EPA water quality standards.

This paper deals with short review and the determination of seven heavy metals, namely Cu, Fe, Mn. Zn, Ni, Cr and Pb in the groundwater of different sites of two districts (Sehore and Bhopal) of Madhya Pradesh.

A field study has been taken up in a newly developing area of Jalore city (Rajasthan), a semi-arid region receiving an average normal rainfall to 560 mm. The study of one year duration revealed that water quality of the domestic wells is fast deteriorating.

In the present study, samples of ground and wastewater were collected from Pali, Rajasthan and analysed for relevant parameters. The results of the analysis of ground and wastewater showed the high range of toxic heavy metals and other parameters in the ground used for potable purposes.

Studies on the environmental distribution of radionuclides, namely 226 Ra and 228 Ra are important in the context of external and ingestion hazards evaluation. The Cochin backwater, located in the south-west coast of India is a potential sink for anthropogenic inputs of natural radionuclides. The estuary in its surroundings is located downstream of industrial complexes.
