Vinyl chloride is a colorless odorless gas used in the production of PolyVinyl Chloride (PVC) plastics and in numerous industries. Vinyl chloride is also a known human carcinogen and the US EPA’s Maximum Contaminant Level (MCL) in drinking water is 0.002 mg/L or 2 ppb. The vinyl chloride concentration in the soil outside of a plastic factory is 0.007 mg/kg, and the soil has a 15% organic content. Vinyl chloride (chloroethene) has a reported octanol-water coefficient equal to 4. Estimate the organic carbon normalized partition coefficient, Koc, using the estimation procedures based upon equations 2.73 and 2.74 and the sediment/water partition coefficient. Use the sediment/water partition coefficient to predict the possible equilibrium concentration of vinyl chloride in the groundwater.
