"An exploratory investigation was conducted to assess whether the widely-used herbicide glyphosate is present at detectable concentrations in shallow groundwater in Canada. An analytical method that combines ion chromatography with tandem mass spectrometry was developed to measure glyphosate at trace concentrations (< 0.1 pg/L). Samples of shallow groundwater were collected from readily available rural monitoring sites in British Columbia, Saskatchewan, Ontario, New Brunswick and Prince Edward Island. Thirty-two percent of groundwater samples were found to contain detectable quantities of glyphosate, at concentrations ranging from 0.0 Hg/L"--Abstract.
