A 5-m diameter tank was used to store water pumped from a contaminated aquifer. The tank has been placed down-gradient of the area of contamination where the underlying aquifer was not contaminated. The accidently suddenly leaked all of the contents. The water in the tank has a Concentration of 23.4 mg/l of Trichloroethane (TCA). The spill was located under the tank. The aquifer has an average linear groundwater velocity of 0.033 m/day. Assume that the tank was centered on a grid at location x=0 and y=0. There is a monitoring well located downgradient at x-7.4 m and y=1.1 m. The transverse dispersivity is assumed to be 10% of the longitudinal dispersivity. What will be the concentration of TCA be in the monitoring well 120 days after the leak?
