DENITRIFICATION OF CONTAMINATED WATER INTRODUCTION:- This is an eco-friendly and economical project. In this we want to show how to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying bacteria

Water Resource Plan: Declining Fish Stock According to National Geographic News only 10% of the big fish in the ocean are left (2003). Many fishermen disagree with this figure and say their fishing hauls have not been affected. Environmentalists say that if something is not done to halt the mass fishing industry many species will become extinct. Fishermen say that if their industry is halted in any way it will affect jobs and the communities that depend on the fishing industry
