The main purpose of this study was to evaluate the effects of irrigation with polluted water on soil properties in two water treatment as river water and well water during two years on Gharesoo River located in Dorodfaraman district, in 20 km south of Kermanshah. This study was performed in three soil layers 30, 60 & 90 cm with three replications in a randomized complete block design. Different soil properties including Gradation curve, coefficients of uniformity (Cu) and curvature (Cc), saturation hydraulic conductivity (Ks) and other parameters such as bulk and practical density (ρ b & ρ a) and porosity (η ) were determined. The results of statistical analysis showed that there was no uniform trend between various parameters. Using the polluted water caused a significant difference at 1% level on saturated hydraulic conductivity and uniformity coefficient at 5% level on curvature coefficient but on the other soil properties, no significant difference was found. Gradation curve of contaminated water had been transferred to the lower and right that this represented an increase of particles size. Also, the use of contaminated water increased uniformity and curvature coefficients then it improved these coefficients and the soil was more non-uniform. The results showed that irrigation with polluted water in loamy soil increased saturated hydraulic conductivity ratio but it decreased bulk and practical density significantly. It can be concluded that the use of polluted water increased the soil porosity.
