Development and effective utilization of groundwater resources is essential in arid and semi-arid regions for activities such as water supply and irrigation. The present study aims to analyze, statistically, the groundwater data at the piezometric stations of upper Swarnamukhi basin in the drought prone Rayalseema region of Andhra Pradesh and to develop relationships through multiple linear correlation and regression analysis.

Long-term pumping tests were carried out on Kasai river bed in connection with augmentation of existing water supply of Kharagpur Municipal town in the district of Midnapore (West), West Bengal to cater to the need of growing population as well as industrial units.

Nitrate has become of the key environmental issues because of its implications on human and animal health. Nitrate enters in the human body through the use of ground water for drinking and causes number of health disorders. In Rajasthan, ground waters of Nagaur, Barmer, Bikaner, Churu, Ganganagar, Hanumangarh and Jhunjhunu districts were enriched with high nitrate.

Delhi is an old town, which has gradually grown into a populous city. It is one of the important business centers of India and thickly populated as well. Since the last decade, drinking water problem has created havoc in the city. In this study, we collected 32 drinking water samples through out Delhi. Different parameters were examined using Indian standards to find out their suitability for drinking purposes. During this examination mainly the physico chemical parameters were taken into consideration.

The water quality index (WQI) was calculated for the assessment of ground water quality near to the dye user industry. For the calculation of WQI physicochemical characteristics of groundwater near by dyeing-printing, pulp-paper and tanning industrial areas were studied.

In this study, templated mesoporous silica material (MS) is modified by aluminium impregnation and arsenate removal kinetics is tested.

Steel Melting Shop-1 (SMS-1) is one of the prime shops of Bhilai Steel Plant, which has a capacity of producing 2.5 MT of crude steel. It follows the conventional route in which steel is produced through twin hearth furnaces and is cast as ingot moulds. An alternate cost effective arrangement was designed, developed and implemented for the uninterrupted direct supply of chemically treated water from water chemical treatment plant (WCTP).

It has been roughly assessed that the amount of iron wasted due to corrosion is one-fourth of the world production. The direct loss due to corrosion in India amount to Rs 200 crore/annum while money spent annually in controlling corrosion is the order of Rs 50 crore. The water quality plays a important role in corrosion.

To measure impact of ecological change in Chittagon Hill Tracts after the installation od dam Kaptai in 1955 on siltation, Bangladesh Water Development Board has conducted siltation study several times from 1978.

Comparison has been made between the drinking water specifications as per IS 10500 - 1991, CPHEEO manual and the guidelines issued by WHO. There is a need to redefine some of the parameters of drinking water in our standards.
