Broward County citations resulted in environmental assessment work be- tween 1985 and 1992. A contamination assessment and subsequent remedial actions indicated petroleum and chlorinated solvent impacts were present in the soil and groundwater. EPA became interested in the site while investigating groundwater contamination in the vicinity of the Peel-Dixie Wellfield, located north of the facility. Subsequent investigations lead to the inclusion of the site on the National Priority List(NPL) da- tabase in March 1998. Administrative responsibility for the site was divided between Federal Superfund, to address the non-petroleum chlorinated solvents which have extended offsite, and the State of Florida Petro- leum Cleanup Program to address the petroleum impacts. A Conditional No Further Action (NFA)was requested for the petroleum impacts by Golder&Associates in 2003, subsequent to four(4) rounds of groundwater sampling and analysis of five onsite shallow monitoring ' wells (SMW-1 through SMW-5). While the Conditional NFA was considered by FDEP, a draft Restrictive Covenant for a deed restriction was not provided(FDEP, 2003). ' The FDEP comments letter indicated that any future sampling conducted to demonstrate that the ground- water at the site has attenuated to unconditional NFA levels,for the purposes of lifting a deed restriction and issuing a superseding unconditional NFA, would require sampling of SMW-1 through SMW-5 for specific historical parameters, including BTEX, PAHs, lead and chromium. In August 2006, ECT was designated as the cleanup contractor by the State of Florida. ECT met with a ' Broward County Environmental Protection Department (EPD) representative to review current site condi- tions and to develop a scope-of-work. Based on the groundwater sampling event conducted in December 2006, petroleum constituents were identified on the property above GCTLs and natural attenuation levels. ' ECT conducted quarterly monitoring and groundwater results for sampling events conducted in 2007 through 2010 continue to indicate that elevated concentrations of petroleum constituents exist above the GCTLs. ECT conducted semi-annual groundwater monitoring. Date Completed: 2010 Total Cost $57,264 1 1 1 _ _ Envertizer 47 Technology Inc.
