What is Air Sparging?

December 28, 2022

Air sparging is a soil remediation technique that involves injecting pressurized air into the ground to help remove contaminants from the soil. It is often used in conjunction with other remediation methods, such as soil vapor extraction or bioremediation, to effectively clean up contaminated sites.

Air Sparging Process

During the air sparging process, a series of small holes are drilled into the ground, and air is pumped through these holes using a specialized machine. The air creates bubbles in the soil, which help to loosen and lift the contaminants to the surface. This process is repeated several times to ensure that the soil is fully cleaned.

One of the main advantages of air sparging is that it is relatively non-invasive, as it does not require the excavation of large amounts of soil. It is also less disruptive to the surrounding environment, as it does not produce any hazardous waste products.

Air sparging is most effective at removing volatile organic compounds (VOCs), such as gasoline and solvents, from the soil. It is not as effective at removing heavy metals or other non-volatile contaminants.

There are a few potential drawbacks to air sparging, however. It is expensive, as it requires specialized equipment and a large amount of pressurized air. It may also be less effective in soils that have a high clay content, as the clay can bind to the contaminants and make them harder to remove.

Overall, air sparging is a valuable tool for soil remediation, particularly for sites contaminated with VOCs. It is a relatively non-invasive and environmentally friendly method that can help to effectively clean up contaminated sites and make them safe for future use.

Air Sparging in Soil Remediation

Soil remediation is the process of cleaning up contaminated soil, while environmental restoration is the process of returning an environment to its natural state after it has been damaged by human activities or natural disasters.

Soil remediation is necessary when soil becomes contaminated with hazardous substances, such as chemicals, oil, or heavy metals. These contaminants come from a variety of sources, including industrial activities, spills, leaks, and improper disposal of waste. Soil remediation involves identifying the source of contamination and removing or treating the contaminated soil to reduce or eliminate the risk of harm to human health and the environment.

Environmental Purposes

Environmental restoration involves a range of activities, including the restoration of ecosystems, habitat restoration, and the restoration of natural resources such as water and soil. Environmental restoration also involves the removal of pollution and the restoration of damaged or degraded habitats. The goal of environmental restoration is to repair or restore an ecosystem or habitat to a healthy and functional state, and to protect and preserve natural resources for future generations.

To aid in these efforts, Alliance Environmental utilizes air to help return contaminated areas to their natural state. Air sparging is an incredibly technical process, and there is significant planning that goes into it. Our experts are equipped with the tools and technology to fully remediate contaminated environments. If you are dealing with any environmental hazard, give us a call!
