Local groundwater has been contaminated with three industrial solvents. We wish to treat 1500 gpm of the water using air stripping in a column with 12 theoretical stages. What is your recommendation for the required air flow rate (in SCFM) to produce water that meets EPA standards. Use the data below for your solution. Please also calculate the concentrations of the organic species in the cleaned water. The concentrations are in ppm by weight.

Compound	K-Value	Conc. In Groundwater (ppm)	EPA limit (ppm)
1,2-Dichloroethane	60	85	0.005
Trichloroethylene	650	120	0.005
1,1,1-Trichloroethane	275	145	0.2
