Chlorination of power plant cooling water is extensively used as a means of controlling biofouling. This practice presents the potential for formation of halogenated organic compounds hazardous to man and his environment. Accordingly, the organic composition resulting from the chlorination or relatively pristine estuarine waters of the northern Olympic Peninsula is currently under investigation. Organic matter is extracted by passing large volumes of seawater over columns of XAD-2 macroreticular resins. Examination of ether extracts from the resin columns using capillary gas chromatography has revealed the presence of halogenated methanes, as well as other electron-capturing components, that are not found when unchlorinated seawater is sampled. Examination of the unrefined chlorinated seawater extracts using gas chromatography/mass spectrometry has revealed a complex mixture which generally was not separable into individual components, even when high efficiency WCOT capillary columns were used. As an aid to the GC/MS investigations, the concentrated XAD-2 column ether extracts were further fractionated using high speed liquid chromatographic techniques. The samples were first separated into molecular weight fractions using a microstyragel column, and then further separated into fractions of increasing polarity using a water-deactivated silica gel column. Fractions were thus obtained which give baseline separation of components and which are more amenable to GC/MS investigation.
