    In this study a multi-element analysis was conducted on the contents of the sediments found at three different sites in the Kapulukaya Dam Lake between May 2007 and November 2007. The elemental analysis of the sediment samples was carried out by using the technique of Polarized Energy Dispersive X-ray Fluorescence (PEDXRF). Of twenty three elements, Cr, Ni, Hg demonstrated high levels of contamination at all sites and As at site 3 according to the criteria set for threshold effect concentrations and probable effect concentrations. The accuracy and precision of the technique employed for conducting the chemical analysis were demonstrated by analyzing the G01-GSD-09 sediment and the K04-NIST-2704 river sediment. Measured concentrations reached at average of 92.7 % and 89.9 % accuracy on the standards used, respectively. The present investigation revealed the effectiveness of this technique in analyzing the sediment content.
