A Practical Approach for the Selection, Pilot Testing, Design, and Monitoring of In Situ Air Sparging/Biosparging Systems

The use of in situ air sparging (IAS) has increased rapidly since the early 1990s, and it is now likely to be the most practiced engineered in situ remediation option when targeting the treatment of hydrocarbon-impacted aquifers.

Description
Summary:The use of in situ air sparging (IAS) has increased rapidly since the early 1990s, and it is now likely to be the most practiced engineered in situ remediation option when targeting the treatment of hydrocarbon-impacted aquifers. To date, IAS system design has remained largely empirical, with significant variability in approaches and results. Here, the valuable knowledge gained from IAS studies and applications over the past decade has been integrated into a new paradigm for feasibility assessment, pilot testing, design, and operation. The basis for this Design Paradigm, the initial feasibility assessment, monitoring, and the overall design approach are discussed in detail here; other referenced documents contain the details of specific recommended activities. The proposed design approach is unique in that it contains two design routes; the first is a non-site-specific approach requiring minimal site characterization and testing (Standard Design Approach), while the second is a more site-specific approach (Site-Specific Design Approach).
