The Munisport Landfill site occupies a 291-acre parcel of land within the city limits of North Miami, Miami-Dade County, Florida. The site is the location of a former municipal landfill that operated from 1974 to 1981. The landfill resulted from the filling of low-lying wetland areas with construction debris and solid waste in an effort to raise the elevation of the land for the construction of a cultural and trade center known as Interama. Because the solid waste was disposed of without the use of a liner or leachate control mechanisms, rainfall percolating through the solid waste has caused the release of contaminants into the underlying ground water and discharge into adjacent surface water. A Remedial Investigation completed by EPA in 1988 and a water quality and toxicity assessment completed in 1989 found that the landfill posed no threat to human health, but that it did pose a significant threat to aquatic organisms in the adjacent wetlands.
The main contaminants found in the ground water were base neutral acids, inorganic compounds, heavy metals, polycyclic romatic hydrocarbons (PAHs), pesticides, and volatile organic compounds (VOCs).
Site Cleanup Plan
The Record of Decision (ROD) for the site was issued in 1990. Major cleanup elements for the site included:
- Interception, collection, and treatment of leachate-contaminated ground water prior to its emergence in the wetland preserve.
- Construction of a hydraulic barrier using a system of ground water recovery wells and an air stripping treatment.
- Closure of the landfill under the direction of the Florida Department of Environmental Regulation.
Tidal restoration of the wetland area, including Biscayne Bay Aquatic Preserve and the State of Florida mangrove preserve, was completed in September 1995. Construction of access roads and recovery wells for the hydraulic barrier was completed in 1996.
A draft design for the ground water treatment and disposal system was submitted to EPA in 1996. However, after extensive study of the changes in water quality and toxicity conditions in the mangrove preserve area, EPA concluded that increased tidal circulation was adequate to address the threat to the environment. A ROD amendment was issued stating “No Further Action” was required under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the site was deleted from the National Priorities List on September 24, 1999.Site cleanup activities have been led primarily by potentially responsible parties (PRPs) with oversight by EPA.
In 1992, the PRP entered into an Administrative Order on Consent with EPA to perform the Remedial Design and Remedial Action (RD/RA) described in the ROD.
EPA has conducted a range of community involvement activities at the Munisport Landfill site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices, interviews, and public meetings on cleanup activities and updates.
The state and county are expected to oversee the closure of the landfill. No Five-Year Reviews are required for the site. No further updates are warranted at this time.
