The underground water containing 2.5-69.5μg SeL-1 used for irrigating transplanted rice grown in Se-contaminated area resulted in a net Se addition in soil up to 881gha-1y-1; possibly further aggravating the Se-toxicity problem. Presence of substantial amount of Se in rock samples and sediments of seasonal rivulets suggests that Se-rich materials are being transported from Shiwalik hills and deposited in regions where seasonal rivulets end up.
