This study investigates the concentration levels of the free fatty acids (which are also important organic pollutants) in surface waters (rivers, streams and lakes) of South-Western Nigeria that are devoid of adequate information. The standard methods based on lipid extraction and isolation and methylation of the free fatty acids were modified and used for the analysis of the free fatty acids in the water samples. BF3-Methanol was used as the methylation reagent. Gas chromatography based on flame ionization detector was used for quantitative analysis of the complex mixtures of the free fatty acids. The average concentration levels of FFAs observed in all the surface (river) water samples of the dry and wet seasons are 24.1431.73 ?g/L and 23.6825.67 ?g/L respectively while those of tap waters samples are 21.42?5.77?g/L and 34.30?4.61?g/L for dry and wet seasons respectively. These represent the baseline data on which further studies on FFAs in surface waters and tap waters of Nigeria could be based. It is concluded that most of the FFAs in the surface waters circulated into the treated drinking waters and that the water treatment plants in the study area have minimal effect on the removal of FFAs (trace organics) from the raw surface waters of Nigeria.
