PatPat1 Posted March 4, 2015 Share Posted March 4, 2015 So I'm having trouble with one of my questions for my hydrology assignment and I would appreciate it a lot if one of you could help me. Consider an aquifer contaminated with an aqueous phase and a sorbed phase. The organic carbon content (foc ) is 0.0025, the porosity is 40%, bulk density is 1.4 g/cm 3 , and log Koc is 2.2. For a unit volume of aquifer, calculate the percentage of mass in the solution (aqueous) phase and the percentage of the mass in the sorbed phase. How would i go about calculating the mass in the solution of the aqueous phase. I found the Kd by doing Koc=Kd/foc Link to comment Share on other sites More sharing options...
PatPat1 Posted March 4, 2015 Author Share Posted March 4, 2015 Anyone have any idea what i should do? Link to comment Share on other sites More sharing options...
studiot Posted March 5, 2015 Share Posted March 5, 2015 (edited) You need first to calculate the total solids, but I am not clear what the units of your organic carbon content are. Then I suggest you calculate the partition coefficient, Kp whichdivides this up between the phases, following the priocedure in this Environmental Protection Agency (EPA) document http://www.epa.gov/superfund/remedytech/tsp/download/issue6.pdf Edited March 5, 2015 by studiot Link to comment Share on other sites More sharing options...
