Effluent from three New Jersey publicly owned treatment works (POTWs) was analyzed for the presence of semivolatile pollutants using on-column gas chromatography/mass spectrometry (GC/MS) and positive discharge chemical ionization liquid chromatography/mass spectrometry (LC/MS). Wastewater samples were extracted by liquid/liquid extraction and XAD-2 resin adsorption methodology. GC/MS identified 323 different compounds. Ninety-one additional components were detected by GC/MS, but could not be characterized. LC/MS analysis detected 106 compounds with the same molecular weight as those found by GC/MS. More importantly, LC/MS revealed the presence of 95 compounds that GC/MS failed to determine. This study illustrates the need for both GC/MS and LC/MS techniques in environmental analysis. Twenty of the identified compounds are known to have genotoxic and/or carcinogenic activity.
