- Abstract
The study carried out in Samarra City in central of Iraq to study some properties ground soil for selected sites. Survey was conducted and six soil samples were selected from two bore hole at depths (5 m, 10 m, 15 m) in terminal sites, coordinates were determined by using GPS. Soil-testing program was carried out at the Soil Mechanics Laboratory at University of Samarra to tested physical and chemical soil tests. Also evaluation of selected heavy metals Pb2+, Cu2+, Zn2+, Fe2+, were analyzed using Atomic Absorption Spectrophotometer (AAS). Test results of physical properties showed that the soil in upper layer to 10 m was sandy soil with gravel or silt, clay and the soil in under layer was gravelly with sand or silt, clay. According to Atterberg limits, the soil specimens were partially cohesive and had low plasticity (ML). The specific gravity values of the examined soils were ranged between 2.51-2.63 and permeability coefficient values were ranged between 1.441*10-3 to 1.694 *10-2 cm/sec, which refers to that the soil was medium to high permeability in the upper layer and decrease with depth. Regarding chemical properties, percentage of pH registered value (6.81-8.1), while the Sulphats, and chlorides recorded value were (13-25)% and ratios with means reached (16.5-31.5) for carbonates. From other hand heavy metals values indicated a homogenous distribution decrease with depth follows as Pb2+ < Fe2+ < Zn2+ < Cu2+ with means (61.9-125.15), (4.25-12.45), (2.65-11.6) and (1.8-4.65) respectively.
