Phenols are produced during in various industrial activities including textile, medicine, plastics, paper, paints, pesticides, disinfectants productions. Phenols cause taste and odor problems in drinking waters even in small concentrations. In higher concentrations however, phenols are toxic for humans and aquatic life. Phenols are classified as priority pollutants by EPA and EC and maximum allowable concentration is set as 0.5 μg/L for phenols. In this work, water samples taken from drinking water sources and well waters are analysed in terms of phenol, 2,4-dichlorophenol (2,4-DCP), 2,6- dichlorophenol (2,6-DCP), 2,4,6-trichlorophenol (2,4,6-TCP), 2,3,4,6-tetrachlorophenol (2,3,4,6-TCP) and pentachlorophenol (PCP). Analyses were carried out according to Method 8041A given by EPA. Extraction method was optimized modifying Method 3510C by EPA. Recovery ratios in the analyses of fortified samples and detection and quantitation limits were determined using the optimized method. Phenols in water samples were derivatized by Pentafluorobenzylbromide (PFBBr) derivatization method following the extraction step. Samples were cleaned-up according to Method 3630C by EPA. After derivatization analyses were carried out using Hewlett Packard 5890 series II gas chromatography equipped with DB-5 capillary column, electron capture detector (ECD) and 6890 series autosampler.
