A procedure was developed for encasing undisturbed soil monoliths in a 0.57‐m diam, 0.85‐m deep steel casing. The casings are available from barrel manufacturing companies, and other equipment is easily made or leased locally. This equipment includes a specially designed frame that holds the thin walled casings during filling. The technique has been successfully used in soils with textures ranging from sandy loam to clay. Bromide breakthrough curves were symmetric for the majority of the encased monoliths. This suggests that side wall boundary flow contributes little to solute mobility through the encased soils. This simple test will allow the user to discard defective monoliths.
