1. The aquifer underneath a site (T = 20 C) is contaminated with 1,1,1-TCA (CH:C13). The aquifer porosity is 0.35 and the dry bulk density of the aquifer material is 1.6 g/cm? A groundwater sample contains 600 ppb of 1,1,1-TCA. Assuming that the adsorption follows a linear model, estimate: (a) The 1,1,1-TCA concentration adsorbed on the aquifer material, which contains 1.0% by weight of organic carbon (b) The partition of the 1,1,1-TCA mass in the two phases (i.e., dissolved phase and adsorbed onto the solid phase)
