Site Background

The Kassauf-Kimerling Battery Disposal site (also referred to as the 58th Street Landfill site) is located in Tampa, Florida. It includes a former peat extraction area later used as a landfill in the 1970s. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1993 because of contaminated sediment, soil, surface water and groundwater resulting from past waste handling operations. EPA, the Florida Department of Environmental Protection (FDEP), and Gulf Coast Lead, Inc., Mr. Kassauf and Mr. Kimerling, the site’s potentially responsible parties (PRPs), 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. By monitoring groundwater, placing institutional controls on the site property and undertaking Five-Year Reviews, EPA, FDEP and the site’s PRPs continue to protect people and the environment from site contamination. After cleanup, EPA took the site off the NPL in 2000.

Stay Informed and Involved

The 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, interviews and information meetings. Site Repository: Tampa Hillsborough Library 900 N. Ashley Dr. Tampa, FL 33602

EPA’s Involvement at this Site

The less than 1-acre site is located in Hillsborough County, just north of Columbus Drive on the east side of 58th Street in Tampa, Florida. The site includes a canal, cut through the landfill in the late 1970s, that connects marshes to the east and west of the site. Undeveloped land borders the site to the north, commercial businesses border the site to the south, a wetland borders the site to the east and 58th Street borders the site to the west. The 62nd Street Dump Superfund site is located approximately one-eighth of a mile east of the site. Peat extraction took place at the site prior to the 1970s. In the 1970s, Gulf Coast Lead, Inc. filled the peat pits with cracked rubber and lead-acid battery casings and then covered the area with a layer of sand. During this time, a canal was cut through the fill material to connect the western and eastern marshes to promote surface drainage at the site. The fenced and secured site is currently vacant. Potential future uses of the site include commercial and industrial land uses.

Site Status

For cleanup, EPA divided the site into two areas, referred to as operable units, or OUs. OU-1 addresses contamination in the landfill area. OU-2 addresses contamination in the marsh and wetland area. In 1989, EPA selected the long-term remedy for OU-1. It included digging up waste material; treating the dug-up materials and soil; and disposing of treated soil in the landfill.

In 1990, EPA selected the long-term remedy for OU-2. It included digging up and solidifying contaminated sediment in the marsh and canal east of the site; flooding the marsh year round; and restoring, establishing or enhancing a new wetland or the existing wetlands and marsh area to compensate for the adversely impacted marsh, also known as wetland mitigation. The remedy also required wetland mitigation next to the site but did not specify any particular requirements. A private citizen owned the area of the marsh affected by contamination from the landfill. The site’s PRPs offered to buy the property but the owner refused to sell it.

In 1994, EPA revised the OU-2 cleanup plan to explain that McKay Bay was an unacceptable alternate location for implementation of the wetlands mitigation because of contamination in the bay. In 1997, EPA revised the OU-2 cleanup plan again to change the location of the wetlands mitigation from McKay Bay to Mobbly Bay, located in Northern Tampa Bay. The project site includes several manmade open-water ponds. In 2010, EPA revised the OU-1 cleanup plan to place institutional controls on the site property to make sure areas addressed by the cleanup plan are not disturbed without the prior permission of EPA and FDEP.

Ground water monitoring is ongoing. EPA and the site PRPs plan to place additional institutional controls on the main facility at the site and the marsh east of the site. EPA completed the last Five-Year Review in 2014.

The site is secure aand not threatened by approaching hurricanes.

Work to Protect Human Health and the Environment

Gulf Coast Lead, Inc., Mr. Kassauf and Mr. Kimerling, the site’s PRPs, lead site investigation and cleanup activities, with oversight provided by EPA and FDEP.

EPA conducted site investigations from 1985 to 1988 to identify contamination in soils and surficial groundwater at the landfill as well as in surface water and sediments in the marsh next to the site.

In 1994, PRPs completed cleanup activities for OU-1 and OU-2. In 1997, PRPs agreed to start the Mobbly Bay wetland mitigation project. All construction at Mobbly Bay has been completed. In 1998, PRPs began groundwater monitoring. In 2000, after completion of cleanup activities, EPA took the site off the NPL.

EPA completed the site’s third Five-Year Review in 2014 and found that the groundwater
monitoring data continues to confirm the effectiveness of the soil stabilization used in the cleanup approaches for OU-1 and OU-2.

Sampling and Monitoring

Ground water monitoring is ongoing to confirm the effectiveness of the soil stabilization used in the cleanup approaches for OU-1 and OU-2.

Site Risks

Risks and pathways addressed by the cleanup include health risks from people ingesting or touching contamination in groundwater, soil, surface water and sediment. Contamination resulted from waste handling practices at the site. The Southwest Florida Water Management District has listed the site and nearby surrounding area as a groundwater delineation area, which means all wells placed in the area require the District’s approval.

The EPA conducted site investigations but later negotiated legal agreements with the site PRPs to clean up the site. The PRPs continue to fund site cleanup, monitoring and oversight activities.
