You accidently spill gasoline onto your lawn while filling your lawnmower. You act quickly and measure the rate of diffusion into the soil at 2 x 10-3 g/m2*s. The porosity of the soil in your backyard is 25% and the effective diffusion coefficient of gasoline is 1.6 x 103 m2/s. If the original concentration of gasoline in the soil was 50 g/m³ and the water table is 10 meters below the surface of the ground, are you concerned about the gasoline contaminating the groundwater?
