The Toastmaster Macon Superfund Site (site) encompasses a light industrial and residential area of Macon, Missouri, where trichloroethylene (TCE) has been detected in the groundwater, soil gas, and indoor air at the former Toastmaster small-appliance manufacturing facility and certain other properties. The facility, located at 704 South Missouri Street, is now occupied by Compton’s Furniture & More, a retail outlet.

The U.S. Environmental Protection Agency (EPA) Region 7 has reached settlements with the Potentially Responsible Parties (PRPs) Compton’s LLC, Spectrum Brands, Inc., and Cooper Industries, LLC, the current and previous owners of the facility, to address TCE contamination at the site.

From the mid-1950s to 2001, Toastmaster, Inc., manufactured small appliances at the facility. In 1991, during Toastmaster’s ownership, TCE was discovered to have been released from an above-ground storage tank on the facility, and also found in nearby groundwater. Further investigation found that TCE vapors were present in both the indoor air and sub-slab air of the facility.

In July 2014, the Missouri Department of Natural Resources conducted indoor air and sub-slab soil gas sampling in homes in the immediate vicinity of the facility to determine whether the contaminants from the facility were impacting nearby residences.

The results of this sampling documented elevated indoor air and/or sub-slab levels of TCE in two of the nearby residences. TCE had volatized (evaporated) and entered the indoor air through vapor intrusion. In October 2014, EPA conducted a Superfund removal action and installed sub-slab vapor mitigation devices in the two affected residences.

Sampling was conducted at nearby residences in 2016 and 2017. The responsible parties, through the settlement that EPA reached with them, installed another vapor mitigation device at a third residence.

The EPA is currently soliciting public input for an Engineering Evaluation/Cost Analysis (EE/CA) for a removal action at the Site. An EE/CA looks at environmental conditions and ways to clean up contamination.
