A continuous source has been leaking contaminant for 2 years into a 1-D aquifer. The steady state dilution attenuation factor DAF for the aquifer is 100. DAF = Concentra- tion at source/concentration at receptor well. Source concentration 1200 mg/L (a) What is the concentration of benzene at a receptor well after 2 years. (b) What is the concentration of benzene at a receptor well in 2 years, if there is first order decay at a rate of 0.01 (1/day).
