The US EPA’s Maximum Contaminant Level (MCL) in drinking water is 0.002 mg/L or 2 ppb for Alachlor. The Arachlor 1221 concentration in the soil outside of a factory is 0.028 mg/kg, and the soil has a 12% organic content. Arachlor 121 has a reported octanol-water coefficient equal to 800. 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 Arachlor 1221 in the groundwater.
