Description:
The experimental design and the results of an interlaboratory study for an analytical method to detect purgeable aromatics in water are described herein. The method, EPA Method 602, Purgeable Aromatics, employs a purge-and-trap chromatographic technique for determination of seven aromatic hydrocarbon analytes in water matrices. The three Youden pairs of spiking solutions used in this study contained benzene, chlorobenzene, 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, ethylbenzene and toluene. The six water types used in the study were distilled water, drinking water, surface water, and three wastewater samples from industries employing or producing aromatic hydrocarbons. Twenty laboratories participated in the Method 602 validation study. The participating laboratories supplied their individual distilled, drinking, and surface water samples. Monsanto Research Corporation (MRC) supplied the three industrial wastewater samples. The statistical analyses and conclusions reached in this report are based on the analytical data obtained by the 20 participating laboratories.
