The ground water does not have excess of available oxygen; therefore oxidation that can purify surface water does not occur in deep aquifers. Although most of the ground water are still safe but once it is contaminated there is no practicable way to clean it up. Hence it must be prevented. Since 1960's there is a considerable evidence that nitrate level in water have increased in India. Heavy fertilizers application result in unused nitrate migrating down into the ground water. As a result ground water withdrawn by the well is likely to have measurable concentration of Nitrate and in some region can exceed the recommended limit (44.3mg L-1 NO3). The health hazard of ingesting excessive in water is infant methaemoglobinaemia, thereby reducing the oxygen carrying capacity. In adult stomach, reduction of nitrate leading to endogenous synthesis of N-Nitroso compounds in presence of secondary amines could be associated with cancer of gastro-intestine and urinary tracts as these compounds are highly carcinogenic. Excessive use of fertilizer has seriously affected quality of ground water in Dhar District Madhya Pradesh (India). It is likely that changes in agricultural practice including control in the use of nitrogenous fertilizers and the specification of protection zones around wells and bore wells should be introduced in an attempt to stem the upward trend in nitrate concentration.
