Benzene is dissolved at a constant initial concentration of 300 mg/l and is contained within a landfill in leachate water above bottom liner of the landfill system. It starts to diffuse through the liner at time t = 0. Using Equation Ci (x,t) = C0 erfc x/2(D*t)0.5related narrative, and Appendix A (error function table), calculate the concentration of benzene at its breakthrough location as it diffuses through a 1 meter thick liner (x=1 meters represents breakthrough location where liner fails, contaminant is released), after 50 years. Assume D = 10-6 m2/sec (diffusion coefficient in free standing water) and w = 0.5 (coefficient of tortuousity).

Benzene is dissolved at a constant initial concentration of 300 mg/l and is contained within a landfill in leachate water above bottom liner of the landfill system. It starts to diffuse through the liner at time t = 0.
Using Equation Ci (x,t) = C0 erfc x/2(D*t)0.5related narrative, and Appendix A (error function table), calculate the concentration of benzene at its breakthrough location as it diffuses through a 1 meter thick liner (x=1 meters represents breakthrough location where liner fails, contaminant is released), after 50 years.
Assume D = 10-6 m2/sec (diffusion coefficient in free standing water) and w = 0.5 (coefficient of tortuousity).
