Abstract The work which is described in this report was performed for the purpose of validating, through an interlaboratory study, Method 625 for the analysis of the base/neutral, acid, and pesticide priority pollutants. This method is based on the extraction and concentration of the various analytes followed by their determination through gas chromatography using a low resolution mass spectrometer as the measuring device. Participating laboratories were selected based upon technical evaluation of proposals and upon the analyses results of prestudy samples. The laboratories were supplied with ampuls containing various concentrations of the pollutant compounds. These solutions were aliquoted into four different water types which were subsequently analyzed according to the appropriate method. In addition to the sample concentrates, each laboratory was supplied with an industrial effluent which was used to help determine false positive and false negative data. The data obtained from the interlaboratory study were analyzed employing a series of computer programs known as the Interlaboratory Method Validation Study (IMVS) system which was designed to implement ASTM procedure D2777.
