Özet: Ovacık Village is located in Balıkesir province and is 12 km away from Balıkesir Center. The GPS coordinates of Ovacık Village are 39° 43' 51'' North and 27° 47' 37'' East. The stream sediments in the study area consisted of the erosion of magmatic, metamorphic and volcanic rocks and surface waters and eroded rock particles along the stream bed. The relationship between metals in stream sediments has been investigated on the basis of geochemical properties. As, Cd, Cu, Mn, Ni, Pb and Zn element contents of 23 stream sediment samples were taken from different locations from Ovacık village and its surroundings. The minimum, maximum, medyan, median and standard deviation values of these metals in the stream sediments were calculated and it was observed that the mean values were higher than the standard deviation values. The minimum and maximum values (ppm) of the metals studied As: 7.7 - 51.3, Cd: 0.13 - 0.58, Cu: 25.2 - 70.6, Mn: 661 - 1135, Ni: 8.6 - 33.7, Pb: 12.3 - 57.7 and Zn: 59 - 220 According to the Spearman correlation coefficient values, a strong positive correlation was observed between As - Cu, Cd - Pb, Cd - Zn, Cu - Ni and Pb - Zn metal associations (p <0.01). Factor analysis was made with the obtained analysis results and 3 different factor values were created and analyzed. Factor 1: Cd - Pb - Zn association and 37.01% of the total variance; Factor 2: Cu - Mn - Ni association and 24.7% of the total variance; Factor 3: As and total variance was 18.4%, the total variance value was found to be 80.1%. The spatial distributions of the metals were analyzed using the Surfer 9.0 program in the creation of the distribution maps. As and Cu elements at locations 16 and 17; Mn and Ni elements at locations 3, 6 and 7; Cd, Pb and Zn elements have the highest values in locations 3, 12 and 20, they show a similar distribution.
