Question

) A river sediment contaminated with anthracene (log Koc = 4.32 L/kg) has an organic matter content of 5 percent. (a) Calculate the dissolved concentration of anthracene in the sediment pore water for a sorbed concentration of 50 ppbm. (b) How many days would it take anthracene (retardation factor = 3.0) to travel 50 m in an aquifer with hydraulic gradient of 0.00058, hydraulic conductivity of 250 m/day, and porosity of 0.15?
