. A leaking tank drips 1,1,1-trichloroethane (1,1,1-TCA) into a small stream at a rate of 10 mg/min. Stream discharge is 10 liter/min, and depth is 25 cm. a. What is the maximum concentration of 1,1,1-TCA in water downstream of the tank? b. Does any NAPL accumulate on the stream bottom? Discuss your answer if necessary. c. What is the maximum flux density of 1,1,1-TCA from water to air? Assume a reaeration coefficient of 0.4/hr
