Twenty water samples of various drinking sources were collected from different pockets of greater Jorhat district of Assam during 2001–2002 to monitor pesticide residues. Total residues of HCH, endosulfan and DDT ranged from 0.019–0.031, 0.005–0.007 and 0.025–0.035 ng mL−1, respectively. Pesticides were only detected in the pond and stream samples but not in the tube well and ddep tube well water samples. No synthetic pyrethroid or organophosphorus insecticides were detected in the present investigation. All the water samples contained pesticide residues below the regulatory limit prescribed by European Union (EU).
