In-Situ Air Sparging
Course Highlights

This online engineering PDH course provides guidance for evaluation of the feasibility of in-situ air sparging (IAS) for remediation of contaminated groundwater and soil. This course also describes design and operational considerations for IAS systems.


In-Situ Air Sparging (IAS) is a rapidly emerging remediation technology for treating contaminants in saturated zone soils and groundwater. It is a relatively easy technology to implement and it is well known to regulatory agencies. IAS involves the injection of air, pure oxygen, or other gases below the water table which may result in the removal of contaminants through volatilization or bioremediation. In a less common application, IAS can also be used to immobilize contaminants through chemical changes such as precipitation.


This 14 PDH online course is intended for civil and environmental engineers as well as other technical professionals interested in learning about the design, operation, and feasibility of IAS systems.
