AB  - Serious health problems are linked to excessive nitrate (NO3¯) concentration in drinking water. The aim of the present study was to assess the causes, determine the effects and discuss possible prevention strategies of NO3¯ toxicity in a river basin and in a hilly terrain area of Jahazpur Tehsil, North West India. For this purpose, ground water samples were collected from three different sources: dug wells (DW), hand pumps (HP) and bore wells (BW). Results indicated that water in DW and HP/BW located in the hilly terrain area contained significantly more nitrates concentration as compared to the respective water sources located in the river basin area. Nitrate levels were relatively higher in DW than in HP/BW in both areas. About 50% of the water samples from the hilly terrain and 35% from the river basin showed higher than the permissible limits NO3¯ concentration. Results showed large variation in NO3¯ concentration ranging from 0.28 to 334.40 mg/l, river basin area range was 0.28 to 277.00 mg/l whereas in hilly terrain area 1.72 to 344.40 mg/l. Excessive use of nitrogenous fertilizers, on site sanitation, mismanagement of animal waste and leakage of septic tanks in domestic area were identified as possible causes of excessive NO3¯ concentration in river basin. In the hilly terrain additional causes of elevated NO3¯ include, geogenic activities, high water table compared to river basin and poor well structure. Moreover, shallow DW neighboring to agricultural land, exhibited higher NO3¯ concentration as compared to those in domestic area.
