Abstract :
In the study area, Shahr-e-Ray industrial zone, south of Tehran, petroleum activities have led to aquifer pollution, so that in some parts the thickness of a light non-aqueous phase liquid (LNAPL) on the surface of the groundwater reaches to more than 20 meters. In this regard, estimation of thickness, density and viscosity of LNAPL, is of great importance to understand the quality of petroleum products of aquifer. Regarding the results of measurement, the range of LNAPL thickness in the aquifer vary between 2.73 to 14.305 m and the range of relative density (LNAPL to water) vary 0.78 to 0.83 and the range of viscosity vary 0.60 to 1.91 cst. According to the result in 10 wells the highest thickness of LNAPL is in the eastern and northeastern regions of the study area.
