Abstract:

TECO Peoples Gas System (TECO) operated a manufactured gas plant (MGP) in Tampa, Florida, dating to approximately 1905. Based upon Site-specific complexities, including existing buildings, roadways, trolley line, and a hydrogeologic setting which includes a significant groundwater gradient, Geosyntec identified Multi-Phase Extraction (MPE) as a viable remedy for remediation of the mobile Non-Aqueous Phase Liquid (NAPL) source area. Due to these unique complexities, the fast-track nature of the project, and uncertainties associated with extracting NAPL from the subsurface, the MPE system design included a significant amount of flexibility to facilitate real-time optimization during operations. In under one year, Geosyntec designed, permitted, constructed, and operated an aggressive, innovative and highly flexible MPE system to recover and treat mobile NAPL, groundwater and vapor-phase contaminants. This presentation will provide an overview of how proven remediation technologies were mixed with new techniques to maximize NAPL recovery and maintain a high level of operational flexibility and optimization. Since startup in July 2016, the MPE system has recovered over 8,100 gallons of NAPL as of March 2017, and when combined with dissolved and vapor-phase mass treated, represents over 33 tons of MGP-related impacts from the subsurface.
