Methodology for volatile organic compounds determination in water from wells and springs in Mexico state, Mexico

Abstract

The EPA 524.2 method using purge and trap capillary gas chromatography, electron ionization and flame ionization detection was used to determine volatile organic compounds (VOC’s) in water samples from wells and springs in Central Mexico. The sampling technique was improved to assess the presence of VOC’s in the samples. The preliminary results obtained in 7 sites from the State of Mexico, confirmed the presence of VOC´s from pesticides used in the zone.
