The Hipps Road Landfill Superfund site is a 12-acre site located on the southeastern corner of Hipps Road and Exline Road in Jacksonville Heights, Florida. Landfill operations were conducted on approximately six acres of the site. The landfill area was initially a cypress swamp, and in the mid 1960's, the site owner at the time contracted with Waste Control of Florida (WCF) to use the low lying areas of the property as a landfill. One source of the landfill materials was nearby U.S. Navy Facilities. Landfill operations ceased in 1970 and were covered by a thin layer of soil. The site owner then subdivided the property into residential lots.
In the early 1980's, resident complaints about unusual tastes and odors in private well water led to investigations that identified contamination in the ground water. The City of Jacksonville completed installation of city water lines to the affected area in October 1983 and connected area residents to the city water supply.
Waste Management Corporation (WMC) inherited the site through acquisition of WCF.
The primary contaminants of concern at the site are vinyl chloride, benzene, and other volatile organic compounds in the ground water.
Site Cleanup Plan
The Record of Decision (ROD) for the site was issued in 1986. Major cleanup elements for the site included:
- Proper landfill closure.
- Removal of contaminated ground water with treatment at the local water treatment plant.
- Long-term (20-year) monitoring of ground water after treatment is done.
- Operation and maintenance of the remedy, including: maintaining the ground water recovery system; ground water monitoring; and maintenance of the landfill cap and associated systems.
- Institutional controls, including fencing the site; acquiring affected properties; and putting in place a well drilling ban.
In September 1990, EPA amended the ROD to provide for on-site ground water treatment and disposal.
In August 1994, EPA issued an Explanation of Significant Difference (ESD) to revise the method by which the abandonment of private wells impacted by the site ground water is achieved.
In June 1996, another ESD was issued to allow effluent disposal to the local water treatment plant in lieu of on-site ground water treatment and disposal.
A 2004 ESD modified the ground water treatment from the existing pump-and-treat system to monitored natural attenuation (MNA).
Five homes located on the landfill were acquired by WCF and removed from the site 1988.
In 1989, initial remedial actions including landfill closure and institutional controls were completed. A clay cap system was placed over the landfill and an 8-foot security fence was installed around the site. A perimeter ditch was constructed within the fenced area to carry runoff from the landfill cap. Physical closure of the landfill was completed in April 1990.
In 1994, WCF implemented the ROD-specified ground water pump-and-treat system. In 1996, WCF installed an effluent pipeline to connect the on-site ground water treatment system to the local wastewater treatment plan. After operating the ground water pump-and-treat system with disposal to the local water treatment plant, it was determined that the pump-and-treat system was no longer effective in treating large volumes of ground water with low concentrations of the vinyl chloride and benzene. In 1999, EPA gave approval to WCF to shut down the ground water pump-and-treat system for a period of one year to collect data necessary to determine if MNA would be effective at this site. MNA proved to be effective, and the 2004 ESD for the site changed the ground water cleanup approach to MNA.
Two Five-Year Reviews (FYRs) have been developed for the Hipps Road site – 1999 and 2005.
The results of the 2005 review show that the existing remedy remains protective of human health and the environment. On-going semiannual ground water monitoring results continue to show decreasing concentrations of benzene and vinyl chloride.
In 2010, EPA conducted a Five-Year review and found that the existing remedy remains protective of human health and the environment. The Site has attained all of the cleanup goals in the Record of Decision and so qualifies to be deleted from the National Priority List.
EPA is working with FDEP on processing the NPL Deletion.
Site cleanup activities have been undertaken by potentially responsible parties with oversight by EPA.
In 1989 EPA entered into a Partial Consent Decree with WCF in which WCF agreed to design the landfill cover and ground water recovery system and implement landfill closure and institutional controls.In 1992 EPA entered into a Consent Decree with WCF that required WCF to construct and operate the ground water and treatment system for the site.
EPA has conducted a range of community involvement activities at the Hipps Road Landfill site to solicit community input and to ensure that the public remains informed about site activities throughout the cleanup process. Outreach activities have included public notices and public meetings on site status updates.
WMC is required to continue existing monitoring of the well network and conduct periodic sampling to monitor the concentration of benzene and vinyl chloride in the ground water.
The next FYR for the site is scheduled for 2015. The Site qualifies to be deleted from the NPL since it has attained all cleanup standards set out in the Record of Decision. EPA is working with FDEP to delete the Site from the NPL.
