Abstract: This study covers the investigation of heavy metal pollution in Karadere Stream which is located in Trabzon, East-Black Sea Basin. 10 heavy metal parameters (Pb, Zn, Cr, Fe, Cu, Ni, Al, As, B and Ba) were analyzed on water samples taken from two stations on Karadere Stream every month, covering the period of February 2017 - July 2017. The results of heavy metal analysis were evaluated according to maximum values given in Water Quality Regulation. The results of the analysis showed that Fe, Cu and Al values were exceeded the limit values for both station. The heavy metal pollution index model was found useful to assess the overall pollution level with respect to heavy metals and the values were found above the critical pollution index value of 100 for both station.
