Abstract Improper storage of non-aqueous phase liquids (NAPLs) in oil tanks leading to soil and groundwater contamination is still largely a concern. Thus, remediation of soil and groundwater contaminated with volatile organic compounds (VOCs) continues to pose a major public challenge. Technologies have been developed to optimize cleanup rates while minimizing costs including in situ air sparging (AS) remediation systems. Further understanding of the contaminant transport processes during cleanup can improve innovative in situ remediation techniques such as AS (injecting pressurized air through the soil). In this entry, a literature review on AS history and applications is provided. While AS and soil vapor extraction (SVE) have become the proven technology over the last 20 years, more research is still needed to improve site-specific optimization and performance.
