| Abstract: |
Please note that the text in this document summarizes the Record of Decision for the purposes of facilitating searching and retrieving key text on the ROD. It is not the officially approved abstract drafted by the EPA Regional offices. Once EPA Headquarters receives the official abstract, this text will be replaced. The 5-acre B&B Chemical site is located in Hialeah, Florida. Administrative and manufacturing operations are housed in buildings located in the southwest and south-central portion of the site. Warehouse and storage areas for raw materials and finished goods are located in the eastern and northern portions of the site. Two tank farms are located in the northeast corner and south-central portion of the site. However, only the south-central tank farm is still in use. Approximately four tanks are located in each area, ranging in capacity from 5,000 to 10,000 gallons each. The site is located over the Biscayne aquifer, the sole source of freshwater for South Florida and part of the surficial aquifer system. B&B began mixing products at the Hialeah facility in early 1963 and gradually increased its product line. Chemicals and other products known to have been used by the facility include a variety of solvents, polishes, detergents, oxidizing agents, corrosive inhibitors and metal cleaners. In the mid-1970's, Dade County Department of Resource Management (DERM) inspectors documented the presence of wastewater residues in soakage pits at the site. In August 1985, DERM requested that EPA investigate conditions at the site. EPA obtained a warrant from the Federal District Court to install monitoring wells and sample groundwater and soil. During 1987, B&B had an RI/FS and a remedial action plan, which was later found to be deficient by EPA, prepared by a consulting firm. In April 1989, EPA offered the company the opportunity to conduct the RI/FS and informed them of their potential liability for all costs associated with the site. EPA resampled the site's wells in September 1992, four weeks after Hurricane Andrew. This is the first and final planned remedial action for this site. The remedial action selected at this site would protect human health and the environment from potential exposure to the contaminated groundwater in the Biscayne aquifer. The objectives for the remedy are to prevent disturbance of the site's contaminated soil and to monitor gorundwater quality to confirm that natural attenuation is occurring. Groundwater 1 is Final Action. The media volume associated with this site is not documented. Soil 1 is Final Action. The media volume associated with this site is not documented. The state does not concur with the selected remedy. |
| Remedy: | The selected remedy is natural attenuation of groundwater contaminants; institutional controls to ensure the integrity of the existing asphalt cover; and groundwater monitoring to confirm natural attenuation. The overall present worth costs are $92,400. |
