ESM 222 Fate and Transport of Pollutants in the Environment Lab #4: Modeling Equilibrium Distribution Report Due: 05/09/2008 Objective: Use a numerical fugacity model for estimating the equilibrium distribution of pollutants in the environment. Methods: The models we will use are loaded in the GIS lab and SCF computers, under Scientific Applications/ESM222. The first model is called Level I, and does a “closed system” equilibrium calculation. The second model is called Level II, and allows for transport in and out of the “box”, which is more realistic. First we will use Level I. After a general “tour” of the model, we will do three exercises: 1) Calculate the expected equilibrium distribution in your Air/Water/Sediment experiment from last week You will need to: Calculate the mass of TCE you added to the vial, when you added the aqueous solution Have the volumes of air, water and sediment you added available – remember to correct the volume of air to account for the fact that the vials hold about 42.9 mL, not

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
