DERP-FUDS Opa Locka Airport - Amelia Earhart Park

Defense Environmental Restoration Program (DERP)

Congressional District: 27



Programs and projects are appropriated under Environmental Restoration – Formerly Used Defense Sites (ER-FUDS). The Opa Locka Airport DERP-FUDS property was located in the city of Opa-Locka, Florida, on 3,944.64 acres formerly used as a U.S. Navy Air Station and Blimp Base. The Amelia Earhart Park project site is located within that DERP-FUDS property and was approved for inclusion in the DERP-FUDS Program in June 2004. Contaminated soil and groundwater were discovered during construction of a sewer system at the Amelia Earhart Park. The contaminated area is located within the boundaries of a suspected former Department of Defense (DoD) burial area. Investigations have included soil and groundwater sampling, a ground penetrating radar survey which indicated the existence of buried objects along the remaining route of the sewer pipeline, and a series of excavation efforts to remove the detected buried debris. Sampling results indicate that the most widespread, often elevated contaminant at the site is arsenic.



Estimated Total Cost $4,960,000
Estimated Total Cost to Complete $887,500
Allocation thru FY17 $4,011,300
Allocation for FY18 $61,200



The nature, magnitude, and extent of contamination in soil and shallow groundwater have been adequately characterized in previous investigations; however, characterization for the deeper groundwater is ongoing. Additional deep groundwater assessment for the suspected former DoD Burial Area was completed in FY17. Pending determination that the nature, magnitude, and extent of contamination in the deep groundwater has been fully delineated, a Remedial Investigation (RI) Report containing updated groundwater data, a human health and ecological risk assessment, and a summary of previous soil data results will be prepared. If the RI Report indicates an unacceptable risk to human health or the environment, a comprehensive Feasibility Study (FS) will be generated. The RI and potential FS reports are scheduled to be completed in FY19.
