Reference no: EM131111578

A truck spills 1 gallon of benzene into an aquifer with an area = 50 ft2. Benzene has a solubility of 1750 ppm, and a specific gravity of 0.873. The aquifer has a porosity of 0.25, a hydraulic gradient of 0.004 and a hydraulic conductivity of 1000 gpd/ft2. Assume that the volume of aquifer affected is 500 ft3 and that the concentration of benzene in the water is 20% of its solubility.

a) What is the flow through the aquifer?

b) What is the total mass of benzene that spilled?

c) What is the concentration of benzene in the aquifer?
