Current Site Status
The Florida Petroleum Reprocessors site includes the area where an oil reprocessing facility operated from 1979 until 1992. EPA placed the site on the National Priorities List (NPL) in 1998 because of contaminated soil, sediment and ground water resulting from facility operations. EPA and the Florida Department of Environmental Protection (FDEP) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. Both residents and businesses use the public water system for drinking water. Through ongoing removal actions, ground water treatment and monitoring, EPA and FDEP continue to protect people and the environment from site contamination.
The 1-acre site is located in the Town of Davie in Broward County, Florida, in an industrial park immediately east of the Florida Turnpike. Interstate 95 passes one half-mile north of the site. The area surrounding the site includes industrial, light industrial and commercial land uses. Residential areas are located west of the site, across the Florida Turnpike. Site contamination does not affect these areas. While cleanup was underway, a vehicle and equipment storage facility operated on the southern portion of the site. Several highway billboards are located on the site.
EPA identified the Florida Petroleum Reprocessors site following investigation of the nearby 21st Street Manor Dump site for possible contamination of the Peele-Dixie Wellfield, a public well field. EPA identified ground water contamination near the dump and traced its source back to the Florida Petroleum Reprocessors site. During the investigation, EPA also confirmed that there were no sources of ground water contamination located on the Peele-Dixie Wellfield.
Oil reprocessing operations occurred at the facility from 1979 through 1992 by several entities, including Barry’s Waste Oil, Oil Conservationist, Inc., Florida Petroleum Reprocessors and South Florida Fuels. Operations reportedly included the collection of waste oils, including used motor oil, surplus fuels, marine oils and slops, hydraulic oils, aviation oils and fuels, and oil wastes from local automotive, agricultural and marine industries. After processing, operators delivered waste oils to used-oil marketers, asphalt plants for use as fuel and phosphate mines for use as flotation oil. In 2003, an investment corporation purchased the site property through a tax sale and leased it to equipment storage companies. Currently, the site is vacant.
The reprocessing operators dumped oil into a perforated on-site tank. Leftover waste materials referred to as non-aqueous phase liquids, or NAPLs, moved through these holes into the underlying aquifer, located six feet below the ground surface. As a result, extensive volatile organic compound (VOC) contamination of ground water occurred and spread from beneath the facility to an area over 800 acres in size, resulting in contamination of the Biscayne Aquifer. In 1998, EPA listed the site on the NPL.
Site investigations identified contamination in ground water, sediment and soil that could potentially harm people in the area. The contamination resulted from waste handling practices at the site. Contaminants of concern identified include VOCs, waste oil degradation products and residual, highly concentrated NAPLs.
Ground water at the Peele-Dixie Wellfield meets federal drinking water standards. The Peele-Dixie Wellfield is not in operation.
Nearby residents use the public water supply for drinking purposes and are not at risk of coming into contact with site contamination.
Vapor intrusion is not a concern, as ground water contamination levels are low.
Soil and sediment cleanup on the site property allows for commercial and industrial uses.
The site property is fenced and gated.
Investigation and Cleanup Responsibility / Oversight
EPA leads site investigation and cleanup activities in cooperation with FDEP.
Site Cleanup Plan
In 1997, EPA authorized a series of removal actions to address the source of contamination at the site. In 2001, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Collecting and treating contaminated ground water at the site and from the southern part of the Peele-Dixie Wellfield.
- Using natural processes to break down ground water contaminants.
- Re-starting ground water pumping at the Peele-Dixie Wellfield.
- Long-term monitoring of ground water.
An Explanation of Significant Difference (ESD) was issued in September 2004 to delay the implementation of the Peele-Dixie Wellfield protection component of the remedy due to changed conditions (i.e., City notification that southern PDWF to be moved due to salt water intrusion). Based on this change it was determined that additional groundwater data needed to be collected to verify the validity of the ROD requirement for the air stripper or other system components associated with the "Wellfield Protection" portion of the ROD. During which time the Wellfield will be sufficiently protected through the use of MNA. This decision was based on the current monitoring of wellheads and the following data decision points.
- GW data collected in the southern portion of the current Wellfield
- current and planned changes to the Wellfield
- decreases in Site contamination
An additional Explanation of Significant Difference (ESD) will be completed in the future since the plan to relocate the southern wellfield has now been completed by the City. The ESD will retain the pump and treatment remedy for use if at some point in the future the wellfields in use exhibit impacts from the site and the protection component needs to be reevaluated with the new contaminant concentrations from the site.
Cleanup actions have included removing barrels left on site, removing contaminated site soil, and breaking down remaining source material (i.e., NAPLs) in ground water with a process called bioaugmentation, which uses microbial cultures to break down ground water contaminants. Treatment through bioagumentation is ongoing.
In 1997, parties removed and disposed of numerous containers, including barrels and bulk storage tanks, off site in accordance with local regulations.
In 1999, parties excavated, or dug up, and removed approximately 6,000 tons of highly contaminated soil.
From 2001 to 2003, parties used on-site chemical oxidation to treat contaminants in soil beneath the ground surface (i.e., subsurface soil). This treatment successfully removed the bulk of subsurface soil contaminants.
Damage to the monitoring and injection well network by site tenants delayed the final treatment of contaminated ground water at the facility using bioaugmentation. Tenants damaged and made repairs to the site over multiple years. In 2010, EPA reached agreement with the current site property owner to keep the site vacant. In early 2011, EPA resumed bioaugmentation efforts.
The removal actions have been effective at addressing the source of site contamination. As a result, the site may not need ground water restoration. EPA is continuing to evaluate the appropriateness of the cleanup approach selected in the ROD. EPA implemented long-term monitored natural attenuation of ground water contamination; EPA approved the remedial design for this approach in 2007. Monitoring of natural attenuation is ongoing. Figures 6-9 illustrate how the amount of ground water contamination decreased over time.
Cleanup Coordination and Collaboration
EPA has worked closely with the City of Fort Lauderdale and the South Florida Water Management District to obtain their input and coordinate on cleanup activities. The U.S. Army Corps of Engineers also assisted with a ground water flow model for the site.
EPA negotiated legal agreements with site PRPs to clean up the site. EPA now leads site investigation and cleanup activities in cooperation with FDEP.
EPA has worked with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.
EPA has conducted a range of community involvement activities to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public notices and information meetings on cleanup progress and activities.
An interested community group obtained technical assistance support through EPA’s former Technical Outreach Services for Communities program. This technical support enabled the community to participate in the remedial investigation/feasibility study stage of the Superfund process, prior to EPA’s selection of a cleanup approach for the restoration of ground water.
Long-term monitored natural attenuation of ground water is ongoing and in conjunction with the approved optimization treatment utilizing the enhanced bio-augmentation system ground water remedy.
An ESD will probably be necessary to clarify the implemented remedy and the role of the contingency remedies mentioned in the ROD before the final Close-out Report (COR) is drafted. The ESD and COR efforts will occur when MNA attains the final cleanup goals.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
