  • Dual point adjustable depth air sparging well system
    Patent number: 8096350
    Abstract: An adjustable depth air sparging well system having a fixed depth or secondary air injection point and an adjustable depth or primary air injection point for injecting compressed air into saturated or groundwater regions of the soil's subsurface to remove volatile contaminants from the soil's subsurface. At least one flow-through air sparge packer which is slidably mounted within the well casing of the air sparging well system allows a user to adjust the depth at which the adjustable depth air injection point is set. The flow through air sparge packer is available in one, two and one half and five foot lengths.
