What Is Air Sparging?

Air sparging is an on-site remediation process utilized to treat soil and groundwater that has gotten contaminated by volatile organic compounds (VOCs). In this process, an injection well is drilled into the contaminated soil or water table. Pressurized air is injected through the well into the contaminated material, causing the hydrocarbons within the VOC to change state and dissolve into vapor.

The vaporized air, sometimes called “off-gases,” bubbles up through the soil or water table and is pulled out of the ground for treatment. Typically, the off-gases must be piped through an air-water separator to remove moisture, which can interfere with the treatment. The contaminated off-gases are then sent into an extraction system that removes the toxic contaminants. Finally, clean air that meets air quality standards is released.

Air sparging is a safe process that poses minimal risk to site workers and the surrounding community. Chemicals are not required to treat the contaminated materials, and any hazardous off-gases are contained within the extraction equipment.
