Abstract: Water samples collected from ground water of Agra region were analyzed for the presence of pesticide residues using solid phase extraction and gas chromatographic techniques. Both organochlorine and organophosphorous pesticides viz., malathion, chloropyriphos, γ-HCH, α-HCH, endosulfan (α and β isomers) and isomers of DDT (p'-DDE and p'-DDT) were detected in concentrations much above the prescribed limits. Seasonal variations were observed in the level of pesticide residues.
