TM94-05 Availability of a new Analysis for the Quantitation of Glyphosate Herbicide

The NWQL has prepared an accepted method to identify and quantitate glyphosate herbicide in water matrices. This analytical procedure is an adaptation of EPA Method 547, "Determination of Glyphosate in Drinking Water by Direct-Aqueous-Injection HPLC, Post-Column Derivatization, and Fluorescence Detection." Glyphosate, found in herbicides such as RoundUp and Rodeo, is a widely used and nonselective weedkiller which is considered to be possibly toxic to mammals.
