The 2.75-acre Airco site is a former industrial landfill northeast of downtown Calvert City in western Kentucky. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1984 because landfill disposal activities contaminated ground water and soil. EPA, the Kentucky Department for Environmental Protection (KDEP) and potentially responsible parties (PRPs) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination.
The site shares a border with the B.F. Goodrich Superfund site. Because of their shared history and location, PRPs took Superfund-related cleanup actions at both sites under one approved cleanup plan (a Record of Decision, or ROD). EPA approved the plan in 1988. PRPs implemented the cleanup plan in the 1990s. Some cleanup activities, such as ground water treatment and monitoring, are ongoing.
Site contamination does not threaten people living and working near the site. The landfill area is fenced and secured. Waste in the landfill is capped. Local residents and businesses are not using contaminated ground water for drinking water purposes. By treating and monitoring ground water and undertaking Five-Year Reviews, EPA, KDEP and PRPs continue to protect people and the environment from site contamination. The agencies and PRPs are currently evaluating the need for changes to the site’s approved cleanup plan.
What Has Been Done to Clean Up the Site?
The PRP for the Site (The Linde Group) (formerly Airco)) led site investigations and cleanup activities, with oversight provided by EPA in cooperation with KDEP.
The site’s 1988 long-term remedy included installing a system to remove contaminated groundwater migrating fromt the landfill. Additional cleanup activities included constructing a flood protection dike around the landfill, improving the landfill cap, monitoring ground water, and placing deed restrictions on the site property to prevent residential development and ground water use.
PRPs started treating contaminated ground water in 1992 by installing five ground water extraction wells to pull contaminated ground water from beneath the landfill and stop it from spreading into the Tennessee River. In 1996, PRPs started several cleanup activities required in the ROD, including constructing the flood protection dike, improving the existing landfill cap, installing the leachate and ground water removal systems, combining surface soil and drainage ditch sediment, and installing site fencing.
The PRPs monitor ground water contamination on a biennial basis to make sure the system continues to work properly.
What Is the Current Site Status?
The most recent Five Year Review was published by EPA HQs in 2017.EPA is currently evaluating the long-term monitoring data along with the cleanup plan for the BFG to determine whether modifications the 1988 ROD are warranted.
EPA is currently conducting a Five-Year Review for the Airco and BFG Sites. The review is scheduled to be completed in late-2019. The review is being conducted ahead of the normal review process to address results from the 2015 Five-Year Review.EPA is currently conducting a Five-Year Review for the Airco and BFG Sites.

Enforcing environmental laws is a central part of EPA’s mission to protect human health and the environment. When warranted, EPA will take civil or criminal enforcement action against violators of environmental laws.The EPA negotiated legal agreements with PRPto investigate and clean up the site. The PRPs continue to fund site cleanup, monitoring and oversight activities.
