The Raleigh Street Dump site (RSDS) is located in Tampa, Florida and was used to landfill battery casings, furnace slag, miscellaneous trash, and construction debris. Aerial photographs show that plastic chips of battery casings are visible on the surface throughout the site from approximately 1977 through 1987. Aerial photographs indicate that the material was dumped at the west end of Raleigh Street and “fanned out” mainly to the north and west sections of the site. It is evident that the dumped material was also placed over the southern portion of the site. A battery recycling facility (Chloride Metals, Inc.) was in operation during the disposal period at the eastern end of Raleigh Street at the intersection of Highway 41. It is suspected that material from the battery recycling facility could have been transported to the site and landfilled as well.
The site was initially discovered during an investigation of the area in conjunction with the September 1980 EPA investigation of the Chloride Metals, Inc. facility. A representative from Chloride Metals, Inc. told the EPA investigator that battery case disposal was halted at this location in November 1978. A nearby business owner stated that battery casings and other trash were disposed at this site until July 1980 and that multiple dumping events took place at the site.
Soil/Sediment: Based on results reported in the Expanded Site Inspection and Remedial Investigation (RI) approximately 11,800 cubic yards of contaminated soil and sediment are present at the site.
Ground water: The primary contaminants detected in the surficial aquifer are antimony, arsenic, and lead. 0The surficial aquifer has a high natural salinity and would not be classified as potable water.
Antimony and arsenic are used as alloying metals in lead-acid batteries; therefore, it is also possible that the disposal of battery casings at the site is the cause of the antimony and arsenic contamination in the surficial ground water. Due to the relatively low permeability of the soils in the surficial aquifer and the relatively low mobility of the metal contaminants, the potential of contamination in the ground water is thought to be limited. The extent of contamination in the surficial aquifer is uncertain, but it likely extends to the wetland located just southwest of well MW-5S.
Site Cleanup Plan
The Record of Decision (ROD) for the site was issued in June 2009. Major cleanup elements for the site include:
- Excavate surface and subsurface soil, sediment, and debris containing chemicals of concern above site-specific remedial goal concentrations.
- Perform confirmation sampling and analysis of the excavated areas to ensure that cleanup goals are met.
- Dispose of the excavated material at an off-site nonhazardous disposal facility (Subtitle D landfill), as appropriate. Any soil or sediments with characteristics requiring it to be classified as Resource Conservation and Recovery Act hazardous waste will be treated and disposed at an appropriate Subtitle C treatment/disposal facility.
- Backfill the excavated areas with clean soil to the pre-remedial action grades. Place a 6- to 12-inch layer of topsoil over backfilled areas, grade, compact, seed, and mulch.
- Restore the existing site wetlands that have been adversely impacted by the site contaminants and/or the remedial activities.
- Conduct pump tests and other means of data collection from existing wells for determination of extent of ground water contamination.
- Develop a contingency plan in the event of no or unsatisfactory ground water contamination reduction as documented through monitored natural attenuation ground water sampling.
- Implement institutional controls to limit and monitor activities on site.
A Remedial Investigation and Feasibility Study were completed in 2007.
An extensive ecological assessment was conducted for the site.
A Proposed Plan for cleanup was completed and submitted for public comment in July 2007.
EPA is conducting a range of community involvement activities at the Raleigh Street site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process.
EPA will be initiating Remedial Design and Remedial Action activities at the site.
