The construction of wells for soil water sampling is expensive due to the high cost of drilling and may contribute to the possible spread of pollutants by cross contamination. In this study, a novel small diameter suction lysimeter with a porous ceramic section was designed and tested. The stainless steel ram-tipped lysimeter was constructed so that it could be installed into the ground using a hydraulic ram without the need of predrilling a bore hole. The operating range of the hydraulically-installed lysimeter was compared to that of a lysimeter installed using the standard silica slurry packing technique. The decrease in sample volume uptake due to plugging in the pores of the ceramic section was investigated for the lysimeters installed both hydraulically and with the silica slurry packing, in three types of soil: medium sand, silty clay, and a topsoil clay-sand blend. The operating range for the lysimeters was ascertained in a test chamber filled with a blend of topsoil clay and sand. An investigation of the effect of sampling on the concentration of solutes was performed with aqueous solutions of two hydrocarbon test compounds.
