This problem considers the movement of a benzene plume in a confined aquifer toward a lake used for recreation and drinking water supply. Using IGW-NET, asses the risk, or probability of the contaminant concentration exceeding the MCL at the aquifer-lake interface. Analyze and compare the following situations i) a homogeneous aquifer; ii) a stratified aquifer; and iii) a stochastically stratified aquifer.
