Groundwater flows through soil rock, with a medium permeability equal to 5 m/day and a porosity of 25 %. A chemical spill has caused the pollution of the groundwater in a small region beneath an industrial site. How long would it take the contaminant from that location to reach a drinking water well located 70 m downgradient It is known that soil density is 2.3 g/cm, soil-water partitioning coefficient of the pollutant is 4.2 cm/g.
