You are working for the State of Texas environmental and public health agency. Hurricane Harvey flooded the Houston area, home to many sites now contaminated with organic pollutants. Your job is to figure out what happens to the chemicals at these sites, which are now under water. Because trichloroethylene (TCE), a carcinogen, is one of the most common chemicals at these sites, you decided to determine whether TCE is getting into the flood water in peoples homes. You found the data from the EPA on-line tool. Data for TCE from EPIWIN database are provided to you in equation sheet. A lab measurement indicated that the current partial pressure of TCE in the air above the water is atm. You observed that in addition to exposure to this contaminated water, the residents may be exposed to the TCE in the water. This could happen because the flood water carried the chemical into homes built from materials with low organic carbon content. Maximum concentration of TCE in the water at equilibrium is . The chemical formula for TCE is . Atomic weights of carbon, hydrogen, and chloride are 12, 1, and 35.4, respectively. Determine whether TCE will move from the water into the air at 25 C.
