Canoe Creek Service Plaza
Design-Build Soil and Groundwater Treatment Construction

THE CHALLENGE
Florida Department of Transportation (FDOT), Florida’s Turnpike Authority had a release from the previous underground storage tanks at the Canoe Creek Service Plaza in St. Cloud, Florida.

THE SOLUTION
HCR was hired to complete the remediation of a very large gasoline impacted area for the Turnpike Authority. HCR designed and implemented the solution for Florida’s Turnpike Authority. Construction plans, including recovery system layout, trenching details, well design and underground piping, were submitted to obtain FDOT right-of-way (R-O-W) and Osceola County Building Department permits to begin the construction. Utility clearance was also required for the facility prior to underground installation.

HCR installed an extensive Air Sparge/Soil Vapor Extraction (AS/SVE) system at the service plaza. The system consisted of 70 Vertical Air Sparge Wells and 57 Horizontal Vacuum Extraction Wells. The equipment package consisted of a 40 hp Air Compressor, a 40 hp Multi-Stage Centrifugal Blower and a 1000-SCFM Electric Catalytic Oxidizer. Utilizing its extensive design experience, HCR has incorporated a number of advances achieving a quiet, powerful system, which removed 400 lbs./day of petroleum hydrocarbons at start-up. The system is designed to be obscure within the service plaza. The project was completed under the strict guidelines of the FDOT, Maintenance of Traffic (MOT) protocols, as all of the underground piping was in the R-O-W for traffic entering and exiting the Service Plaza.

THE RESULT
The installation phase of the project was completed within a 6-month time frame. HCR Technicians provide Operation and Maintenance (O&M) at scheduled intervals to monitor performance of the system and cleanup progress.
