Elevated nitrate toxicity in drinking water leads to infant methaemoglobinaemia (blue-baby syndrome), abortions, livestock poisoning etc. The present study was carried out to assess the causes, effects and prevention of nitrate toxicity river basin and hilly terrain area of study area, for this purpose hundred ground water samples were collected from dug wells, hand pumps and bore wells. The results revealed that water in dug wells and hand pumps/bore wells located in hilly terrain area contained more nitrate toxicity compare to dug wells and hand pumps/bore wells located in river basin area, and relatively more nitrate level in dug wells than the hand pumps/bore wells in both areas. About 50% water samples from hilly terrain and 35% from river basin showed high nitrate which was exceeded the permissible limits. The results indicated a large variation in nitrate content from 0.28-334.40 mg/l,  river basin area range was 0.28-277.00 mg/l whereas in hilly terrain area 1.72-344.40 mg/l. The identified possible nitrate sources in river basin area were excessive use of fertilizer in agricultural purpose, on site sanitation, dumping of animal waste and leakage of septic tanks in domestic area while in hilly terrain area including these, geogenic activities and shallow depth of soil zone compared to river basin, poor structure of wells also potential factor of high nitrate. And nitrate content in dug wells located in agriculture land were found more compared to dug wells located in domestic area and also found more in shallow depths dug wells.
