Measuring Colloidal Travel Through Sand Using Fluorescence

Hank Hogan

The poet William Blake evoked the image of seeing the whole world in a grain of sand, but some researchers instead use entire beds of sand to model the movement of contaminants and microbes in soil. Sand is less complex than soil; still, measuring the movement of colloids through the particles has been difficult. UV light illuminates solute (green) and colloid (red) tracers passing through sand beds, which are used as a simple model for soil. Here, colloids from a point source form a narrow plume as they travel downward through saturated sand. Images courtesy of Jonathan W. Bridge,...Read full article
