Site Background
The Anodyne, Inc. site is located on a 4.25-acre parcel of land in the Sunshine State Industrial Park in an unincorporated portion of Dade County, Florida near North Miami Beach. Anodyne, Inc. is believed to have begun operation around 1960. Ownership of the facility changed several times and underwent an expansion in 1968, before closing in 1978. Production activities conducted within the plant included aluminum anodizing, embossing, lithograph development and printing, silk screening, die and diamond cutting, and laminating. Some of the consumer products produced at the facility included colorful decorative trim, control panels, face plates, and equipment dials.
The manufacturing processes were conducted within the Anodyne, Inc. building. Some storage of process chemicals occurred in above ground tanks enclosed in concrete block structures along the south side of the building. It is believed that wastes were discharged via pipes through the building wall directly on to the ground. Another site feature is a 10-inch diameter, 90-foot deep, well located on the south side of the Anodyne building believed to have been used for waste disposal.
The industrial park is located in a mixed residential, commercial, and industrial district of northern Dade County, Florida. The site is bordered on the north by the Palmetto Expressway; on the east by Interstate State 95; to the south by U.S. Route 441 and Biscayne Canal; and to the west by a residential development. Buildings that formerly housed Anodyne manufacturing operations are now occupied by a packaged snack distribution center and a furniture/warehouse facility.
The site overlies the Biscayne aquifer, a shallow water table aquifer that serves as the sole source of drinking water for Dade and Broward Counties.Threats and Contaminants
Remedial investigations of the site have identified two separate and distinct zones of contamination: Zone 1, metal contaminated ground water and soil; and Zone 2, ground water contaminated with volatile organic compounds.
Site Cleanup Plan
The Record of Decision for the site was issued in 1993. For Zone 1, the cleanup approach included:
- Excavation and off-site disposal of contaminated soils along the west and south side of the Anodyne facility.
- Backfilling of excavated soil areas.
- As necessary, treatment and on-site disposal of the shallow plume of metals contamination.
- Excavated soils, which consist primarily of sand, will be used as a base material in the production of portland cement.
For Zone 2, the cleanup approach included:
- Pre-design studies to further define the shallow ground water plume boundary.
- If pre-design studies demonstrate that natural attenuation is not adequate to achieve the cleanup criteria, on-site collection and treatment of shallow contaminated ground water.
- Long-term monitoring of ground water.
- Reinjection of treated ground water into the Biscayne aquifer.
Cleanup Progress
Zone 1: Cleanup activities for Zone 1 areas (metal contaminated ground water and soil) began in 2003 and were completed in 2005. Cleanup activities included soil excavation, shallow ground water sampling, confirmation ground water sampling, and regrading of the excavated areas. A Letter of Completion for Zone 1 was signed by EPA on August 29, 2005 in accordance with the Consent Decree for the Anodyne site.
Zone 2: The design studies for Zone 2 began in January 2000 to further evaluate changes in the distribution of contaminants in the plume. Additional ground water monitoring wells were installed from January to April 2000 and ground water samples were collected in June 2000. Installation of additional monitoring wells was completed in May 2004. This effort allowed for the expanded tracking of the ground water plume. Ground water sampling was completed in June 2004. Additional ground water samples were collected from existing wells to further analyze and determine the level of concentration from previous data collected. A report evaluating the ground water sampling results was finalized in 2007.
Zone 2 work continues with additional monitoring wells. Movement of the contamination plume is relatively active due to influences of ground water recharge and local area wellheads. EPA has an interagency agreement with the Army Corp of Engineers (ACOE) to assist in ground water remediation at the site. A pilot study to assess the treatability of contaminated ground water identified in the deep aquifer was initiated by EPA and the ACOE in February 2009. The pilot study is expected to be completed in 2010.
Enforcement Activities
EPA and the potentially responsible parties for Zone 1 signed a Consent Decree in July 2000 to perform the cleanup activities for Zone 1.
Community Involvement
EPA has conducted a range of community involvement activities at the Anodyne site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public meetings on cleanup activities and ground water monitoring data and activities.
