Release of PCE DNAPL (red) into a water‑saturated heterogeneous sand showing migration along and breakthrough of capillary barriers before accumulating in a coarse sand lens. Black vertical bars are supports on the outside of the front glass wall. Darker region in the middle portion of the sand is caused by variation in lighting. (1 minute)
A discussion of the material in this video is provided in Section 6.1 “DNAPL Migration through Heterogeneous Sand (1 minute)” of the Groundwater Project book “Flow and Distribution of Non-Aqueous Phase Liquids”.
