Water samples from Gaula river and water accumulated in the tension cracks of the nearby hill side which are prone to slide due to complex geotechnical problems and later converge in the river near Amiya village, Nainital district, Uttaranchal, have been analysed geochemically, in order to understand the quality of water and level of contamination.

The importance of environment in our daily life is well known. It adversely affects not only human lives but also to the coming generation. The present paper mainly deals with the methodology of cost benefit analysis which is dependent on the types of project.
