Current Site Status
The Airco Plating Company site is the location of an active metal plating facility. EPA placed the site on the National Priorities List (NPL) in 1990 because of contaminated soil and ground water resulting from plating operations. EPA and the Florida Department of Environmental Protection (FDEP) have investigated site conditions and Airco Plating Company (APC), the site’s potentially responsible party (PRP), has taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not threaten people living and working near the site. Both residents and businesses use public water systems for drinking water. By cleaning up and monitoring ground water and soil and undertaking Five-Year Reviews, EPA, FDEP and the site PRP continue to protect people and the environment from site contamination.
Site Location and Background
The 2-acre site is located in a commercial and industrial area in Miami, Florida, about one mile northeast of Miami International Airport. Metal plating facility buildings and the site’s ground water treatment system are located on site. Businesses surrounding the site include a refrigerant distributor, a door manufacturer, an electrical parts manufacturer and several used auto parts stores. Two mobile home parks that include minority residents are located nearby. The Miami Canal is about two-thirds of a mile southwest of the site. Several other Superfund sites are located within a few miles of the site.
The site has been the location of an active metal plating facility since the 1950s. In 1990, EPA placed the site on the NPL.
Site investigations identified contamination in soil and ground water that could potentially harm people in the area. Soil and ground water contamination resulted from the operation of wastewater ponds on site as well as other waste handling practices. Contaminants of concern include metals and solvents (also called volatile organic compounds or VOCs). Specific contaminants include cadmium, chromium and solvents such as tetrachloroethylene (also called PCE or PERC), cis-1,2 dichloroethene and vinyl chloride. The main threat posed by the site is the release of contaminants into the Biscayne Aquifer, the main source of drinking water for Miami-Dade County.
Ground water treatment has prevented contamination from spreading beyond the site boundary. Ground water contamination does not affect nearby residents and businesses. Ground water treatment will continue until ground water is drinkable. The PRP, with EPA oversight, regularly checks ground water wells to make sure contamination has not moved beyond the site boundary. The PRP and nearby residents and businesses use public water systems for drinking water. The South Florida Water Management District has listed the site and the surrounding area as a ground water delineation area, which means all wells placed in the area require the District’s approval.
Soil contamination remains on site. However, the PRP covered all soil contamination with a concrete cover. The PRP regularly inspects the cover to make sure it remains in good condition. The PRP is currently coordinating with EPA to place a land use restriction on the site property to prohibit any future landowner from using the facility in a manner inconsistent with the site’s cleanup.
Investigation and Cleanup Responsibility / Oversight
The site PRP leads site investigation and cleanup activities, with oversight provided by EPA in cooperation with FDEP.
Site Cleanup Plan
In 1993, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Removing VOCs in soil using soil vapor extraction (SVE).
- Placing a concrete cover over contaminated soils not addressed by SVE.
- Cleaning up contaminated ground water using an air stripping system.
- Discharging treated ground water to the municipal sewer system.
The PRP began treating ground water using an air stripping system in 1995. As of early 2011, the ground water treatment system has treated over 102 million gallons of water.
Also in 1995, EPA began treating soil contamination using SVE. EPA discontinued use of SVE in 1999 after it had reduced VOCs to cleanup goals. In 1999, the PRP also installed a concrete cover over contaminated site soils.
The PRP regularly performs operation and maintenance activities at the site to make sure ongoing cleanup actions continue to perform as planned. Activities include inspections of the site’s ground water monitoring wells and concrete soil cap, and inspection and maintenance of the site’s ground water treatment system. The PRP monitors ground water underneath its metal plating facility quarterly and on nearby properties annually.
The site’s third Five-Year Review, completed in 2011, found that in the short term cleanup actions to date protect people and the environment from site contamination. In the long term, there is a need for additional work.
EPA issued an order and negotiated legal agreements with the site PRP to investigate and clean up the site. The PRP continues to fund site cleanup, monitoring and oversight activities.
RODs and Five-Year Reviews online provide information on specific legal agreements for the site.
EPA has worked with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.
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, a fact sheet and information meetings.
In 2011, EPA issued a public notice in the Sun Sentinel newspaper announcing the start of EPA’s third Five-Year Review for the site. In 2011, EPA also visited nearby businesses and residences to learn about people’s current knowledge of the site and to identify any related concerns. EPA is currently planning a mailing for nearby residents to provide an updated site fact sheet. EPA plans to provide the newsletter in English and Spanish.
Ground water treatment and operation and maintenance activities are ongoing.
EPA completed the last Five-Year Review in 2011 and plans to complete the next Five-Year Review in 2016.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office
