Conference of the NATO Advanced Study Institute on Management and Sustainable Development of Urban Groundwater Systems -- AUG 06-15, 2004 -- Baku, AZERBAIJAN, WOS: 000243256700031, A water-saturated biological denitrification system was employed to remove selected pesticides and nitrate from drinking waters. In the study, approximately 99% nitrate removal was observed, but most of the samples included nitrite. Up to 95% removal of pesticides was also observed. The lowest removal efficiency of nitrate (63%) was observed when the temperature dropped sharply from 18 T to 14 T. Despite such oscillations, high removal efficiencies for trifluralin, fenitrothion and endosulfan (alpha+beta) were observed and the highest nitrite concentration was 16 mg/l in the effluent of the reactor., NATO, INCO-DC Project [CT 970167]; Research Foundation of Cumhuriyet University, The authors are grateful to the INCO-DC Project (Contract ERBIC 18 CT 970167) and the Research Foundation of Cumhuriyet University for financial support
