  • Patent number: 8082981
    Abstract: An multiple point adjustable depth air sparging well system having a multiple air injection points for injecting compressed air into saturated or groundwater regions of the soil's subsurface to remove volatile contaminants from the soil's subsurface. At plurality of flow-through air sparge packer which are slidably mounted flow-through packers within the well casing of the air sparging well system allows a user to adjust the depths of the air injection points. Each packer has attached thereto a pressure regulator which provides compressed air to one of the multiple air injection points.

  • Patent number: 7828495
    Abstract: A supplemental fluid adjustable depth air sparging system which is used to remediate contaminants from groundwater within the soil. An adjustable depth air injection point injects compressed air mixed with a chemical oxidizer or nutrient into saturated or groundwater regions of the soil's subsurface to remove contaminants including chlorinated solvents from the soil's subsurface.

  • Patent number: 6305878
    Abstract: An adjustable depth air sparging well comprising a flow through packer which is slidably mounted within a well casing allowing for vertical movement of the flow through packer within the well casing. Flow through packer includes an inflatable packer fabricated from inflatable vitron tubing, a lower end portion of an air supply tube which has a plurality of openings for providing pressurized air to inflate the packer, and a pair of vitron rubber packer end caps. An air compressor is coupled to the air supply tube supplying pressurized air to the inflatable packer which inflates the packer holding the packer at a fixed depth within the well casing. Deflating the inflatable packer allows for vertical movement of the inflatable packer within the well casing. Positioned at the lower end of the air supply tube is a one way valve through which air under pressure passes to a well screen. The well screen, which comprises the lower portion of the well casing, is mounted in the soil's saturated zone.
