Control of plumes in soils with air sparging

(MEng dissertation by: Siobhan Catney, Will Armitage)

This project was looking at the feasbility of injecting compressed air into the ground to control the movement of water-borne plumes in soils.












This is a plume of dye moving through sand. A high hydraulic head on the right is driving the plume under the barrier and upwards on the left of the barrier. In this case there is no air sparging.


When air is sparged into the soil, the plume is observed to divert around the sparged region.
