An air sparge/soil vapor extraction (AS/SVE) remediation system was designed based on pilot test data. A total of 6 AS wells and 5 SVE wells were to remediate gasoline constituents in the groundwater by directly volatilizing the constituents and supplying oxygen for aerobic biodegradation. The work included preparation of construction plans, specifications and bid documents, construction oversight and quality control, preparation of an APEN emissions notification, performance evaluation, and long-term performance monitoring.
