Broward County Aviation Department
- Air Sparge/Soil Vapor Extraction
- Remedial Action Plan
- Post Active Remedial Monitoring
The Fort Lauderdale-Hollywood International Airport was undergoing over a billion dollars in renovations associated with terminal modernization and runway expansion programs. In preparation of the planned expansion the Broward County Aviation Department tasked us with investigating a former rental car facility which was in the building footprint of the proposed Terminal 4 expansion. We were requested to obtain non-conditional site closure before construction commenced.
The main petroleum plume was moving in another direction, following groundwater directional flow. We installed an Air Sparge/Soil Vapor Extraction (AS/SVE) System to treat the main petroleum plume, after a Remedial Action Plan for the site was approved.
After two years, the shallow petroleum plume had been abated by the installed AS/SVE treatment system to below groundwater and soil cleanup target levels, and we implemented a groundwater monitoring program. Through monitoring we discovered the main petroleum plume had been successfully treated and a RAP modification was prepared and approved. We started the required one year Post Active Remedial Monitoring (PARM) prior to closure. The site showed 4 clean quarters and achieved non-conditional closure.
