Nitrogenous material such as organic matter and ammonia may be oxidized to nitrate by organisms. Nitrate may also be released into the environment by disposal of domestic sewage and use of nitrate based fertilizers. Presence of elevated concentration of nitrates in drinking water poses to have potential health hazards related with methaemoglobinamia. High nitrate is alarming as it indicates possibility of seepage from sewage. Many samples had nitrate within the maximum permissible limits recommended by ICMR, yet most of the water is not potable due to high nitrate. The most efficient way to prevent nitrate impacts is to identify the sources of nitrate and to reduce them at the source. This study shows the important role of the sub soil, combined land use in determining the source of nitrate in ground water. An attempt was made to investigate the ground water quality of northern part of Bijapur district with respect to nitrate and other physico-chemical properties. It was found that a few water samples had elevated nitrate concentration while the rest water samples had nitrate concentrations falling within the standard limits.
