Match the breakthrough curves given in the diagram with the appropriate description given below. Curves represent responses to the injection of a tracer in 1-D soil columns. Choose the best match for each case. 1. Curve for a 1-D continuous injection where the constituients get sorbed to the medium 2. Curve for a 1-D continuous injection with plug flow is observed 3. Curve for an instantaneous source with longitudinal dispersion 4. Curve for an instantaneous source with no dispersion 5. Curve for a 1-D continuous injection with longitudinal dispersion 6. Curve for a 1-D continuous injection with longitudinal dispersion and biodegredation 7. Curve for a 1-D continuous injection in which a fracture existed along the soil column $1_{\mathrm{A}}$ pore volume in a column is the volume of water that will completely fill all of the voids in the column.
