The objective of this study was to determine the contamination degree of Marren Alsaleeb dam’s soils (Hama – Masyaf) and the relation between total and exchangeable Cadmium with the physical and chemical properties of soils. Soil samples were collected from two depths (0-20 cm) and (20-40 cm) along 3 km. The study indicates that soils had different textures. Soil pH was neutral to alkaline. Soil salinity was within the normal range. Soils organic content was between (0.28-3.64%), Results also showed that total calcium carbonate content was high content. Average of the total amount of cadmium in layer ranged between (1.25 – 2.94 mg/kg). Whereas Exchangeable form was between (0.4 – 1.34 mg/kg). Cadmium was accumulated in the topsoil in most of the sampled sites. The highest concentration of Cadmium was in samples locate near the pollution source  and it exceeds  the critical limit (2 mg/kg). Cadmium accumulated in the river bed soil compared by soil of the side. There was a positive coefficient correlation between total amount and Exchangeable cadmium. Positive coefficient correlation between cadmium content with organic matter calcium carbonate  and soils clay content. Linear regression equation showed the significant R2 between the Cd fractions (Total, Exchangeable) with studied soil properties in soils of Marren Alsaleeb dam.
