The river water pollution with Organochlorine pesticides from agricultural activities, industrial activities and domestic sewage has received great attention during recent years. The Organochlorine pesticides are very dangerous and harmful because of their tissue degradation and carcinogenic character in nature. Liquid-Liquid extraction followed by GC-ECD, was used for the determination of a, b, g- HCH, Aldrin, Dieldrin, o,p´-DDT, o,p´-DDD, p,p´-DDD &Endosulfan in Karhera Drain &Hindon River. High concentration of  β-HCH was detected in the surface water collected from Karhera drain (32 ng/l), Mixing point (28.34 ng/l) & D/S of out fall Karhera drain (24.56 ng/l). α-HCH was detected in the surface water collected from Karhera drain (19.8 ng/l), Mixing point (17.45 ng/l) & D/S of out fall Karhera drain (14.3 ng/l). o,p´-DDT was detected in the surface water collected from Karhera drain (5.89 ng/l), Mixing point (4.58 ng/l) & D/S of out fall Karhera drain (3.76 ng/l). o,p´-DDD were detected in the surface water collected from Karhera drain (5.34 ng/l), Mixing point (4.89 ng/l) & D/S of out fall Karhera drain (3.78 ng/l). p,p´-DDD were detected in the surface water collected from Karhera drain (8.43 ng/l), Mixing point (7.27 ng/l) & D/S of out fall Karhera drain (6.29 ng/l). The concentration of α, β-HCH, o,p´-DDT, o,p´-DDD, p,p´-DDD  was found to be much higher than the EC water quality standards in the water samples from sampling location posing a high risk to the common people.
