The designed storm water retention pond for the project spanned two parcels of land, which were discovered to contain petroleum-based contaminants. The pond was scheduled to be constructed early in the project to receive storm water runoff during construction and remain as a permanent storm water pond after completion of construction. The contaminated conditions prevented construction and use of the pond. It was therefore imperative that the site contamination be cleaned up quickly and effectively; otherwise, the construction schedule and budget would be hurt substantially. Site assessment and remedial planning were expedited, requiring close coordination between the involved regulatory agencies, other public agencies, general contractor, and remediation contractor. The design for the contaminated groundwater recovery system included high-recovery-rate horizontal drains, the first such application in Florida, as well as deep vertical wells. The groundwater treatment system employed filtration, clarification, and carbon adsorption treatment. Treated water was discharged into recharge ponds and infiltrated in designated site areas to flush the soils in the vadose zone. This action minimized the rebound effect typical of pump and treat operations that is caused by the interaction of the recovered water table and vadose zone soil contamination. This unique, large-scale groundwater remediation was effective, removing more than 99% of the benzene and 95% of total volatile organic aromatics in 3 months.
