Site Background:The B&B Chemical Site, located in Dade County, Florida is a 4.5 acre site which has formulated industrial cleaning compounds since 1963. In the mid-1970s, the Dade County Department of Resource Management (DERM) documented the presence of wastewater residues in five soakage pits at the site. In 1981 and 1982, construction workers excavating near the site complained of skin burns and irritation. In 1985, DERM requested that EPA investigate conditions at the site. This investigation confirmed the presence of volatile and semivolatile organic compounds in the site's groundwater and soil. A plume of contaminated groundwater had migrated across the street, south of the site. The site has impacted the Biscayne aquifer, a sole-source aquifer, supplying the needs of the City of Hialeah.
Cleanup Progress:
B&B Chemical, Inc., under an agreement with Dade County, operated a ground water recovery and treatment system from August 1988 until the early 1990s. This ground water treatment brought ground water contaminants down to levels which EPA believed were low enough for natural attenuation to finish the job. The implementation of the natural attenuation remedy is considered to have started on the date of first monitoring, December 7, 1995.
The most recent Five-Year Review for the site, completed in 2007, found that the cleanup approaches identified in the ROD are protective of human health and the environment. Performance standards established for COCs in ground water have been attained in all monitoring wells, and the COCs do not impact the nearby municipal well field.
In June 2009, EPA issued an Explanation of Significant Differences (ESD) which required a restrictive covenant to be placed on the property to ensure the long term protectiveness of the remedy. EPA is working with the Florida Department of Environmental Protection and the site owner to get the restrictive covenant in place. Once the restrictive covenant is in place, EPA will begin the process to delete the site from the NPL.
