AB: Intermediate-scale experiments fill the gap between bench and field-scale experiments. They compensate for the missing subsurface heterogeneity in bench-scale experiments and the lack of environmental control and insuffcient sampling in field-scale experiments. A 4.22 by 2.74 by 2.13m intermediate-scale indoor facility that mimics a heterogeneous subsurface environment was constructed. To characterize the facility and to obtain a 3D subsurface contamination dataset, a 20-day point source continuous-injection experiment was conducted. Using 63 Time Domain Reflectometry(TDR) sensors, a salt concentration dataset was collected at a frequency of 20 minutes per measurement per sensor. The experiment data were compared with a finite element model - Princeton Transport Code(PTC) simulation. In the horizontal plain, which contains a point source, the PTC simulation were consistent with the TDR data. At other sampling locations, vertical to this plain, there were siginificant deviations between the PTC simulation and the TDR data.
