Soil Adsorption / Mobility

Using a soil adsorption coefficient (Kd) of 0.17 for 1,4-dioxane measured in a grey clay soil (45% clay, 43% silt, 10% sand) obtained from a landfill site in Ontario, Canada(1), a Koc value of 29 can be derived(SRC) using the soil's organic carbon content of 0.58%(1). A measured Koc value of 17 has also been reported for 1,4-dioxane(2). According to a classification scheme(3), these Koc values suggest that 1,4-dioxane is expected to have very high mobility in soil(SRC).
