Uncontrolled solid waste affects the stress-strain behavior of the soil as well as an environmental problem. In this research, the effect of leachate on the dynamic behavior of sand has been studied and the results were compared with clean sand at different saturation degrees. The modified split molds at 50mm diameter and 100 mm height were used to prepare the polluted soil. Both polluted and clean sand samples were prepared by dry pluviation method. After preparation, the samples in the modified mold were put in the wastewater to keep for different cure times. Then samples were installed on the dynamic triaxial test system at 0.1 Hz and ±σdev/2σ'c =0.28-0.30 cyclic ratio. For saturation, not to change the structure of polluted sand, CO2 and distilled water were not used under the vacuum. Stress control cyclic tests were conducted on both clean and polluted sand consolidated at 100 kPa isotropically. The measured B values varied between 45-93%. Test results show as the B value decreases the number of cycles causing liquefaction increases in both the clean and polluted sand. Leachate makes the sand more liquefiable depending on cure time at the same saturation value.
