Recent experiments have shown that atmospheric radioxenon passing over a sampling site can be transported into the shallow subsurface by barometric pressure changes. The STOMP simulator is used to examine the impact of seven hydrologic/geologic parameters and water infiltration on the imprinting of radioxenon from a transient plume during two pressure scenarios. The maximum concentration of Xe at a depth of two meters and the time of maximum concentration at that depth were calculated for each parameter set and the most impactful parameters were identified.
