  		Fig. 1. Kinetic sorption of (a) estradiol and (b) testosterone to soil from the 0- to 10-cm (closed symbol) and 20- to 30-cm (open symbol) soil depths. Error bars indicate one standard error.

  		Fig. 2. Distribution of measured (a) estradiol and (b) testosterone within conventionally tilled (CT; closed symbol) and no-till (NT; open symbol) soil columns and the quasi-combined model predictions of sorbed hormones (differences between tillages were too small to show separate curves) . Error bars indicate one standard error.

  		Fig. 3. Breakthrough curve of Cl– (+), estradiol (o), and testosterone ({Delta}) through columns of conventionally tilled (CT) and no-till (NT) Cecil sandy loam. Each graph possesses two y-axes. The left y axis represents the relative concentration of hormones (C C0–1). The right y axis represents the relative concentration of Cl– (C C0–1). Solid lines indicate the fitted model generated by HYDRUS-1D. A physical nonequilibrium model was fit to the Cl– data and a quasi-combined physical and chemical nonequilibrium model was fit to the hormone data.
