A rapid, economic, sensitive and reliable method for the determination of epichlorohydrin (ECH) in drinking water is presented. After extraction by methylene chloride, trace-level ECH was quickly concentrated with K-D concentrator. An Agilent 7890A GC System with an Agilent J&W DB-5ms Ultra Inert column were used for ECH analysis. The calibration curves were linear over the range of 0.08–1.60 ng with correlation coefficients greater than 0.9997. Recoveries of ECH at spiked levels of 1.0, and 5.0 µg/L were 104.7% and 107.0%, respectively. The RSD value for ECH reproducibility was lower than 2.21%. The detection limit was less than 0.07 µg/L, which is below the maximum residue limit (MRL) of 0.1 µg/L in European Union regulations for ECH in drinking water.
