The 30-acre Scovill Industrial Landfill site is located in Waterbury, Connecticut. The Scovill Manufacturing Company used this area as a landfill from 1919 to the mid-1970s for disposal of ash, cinders, demolition debris and other wastes generated by the company. The southern, 23-acre part of the site has been developed into residential and commercial properties. The northern part of the site is an undeveloped 6.8-acre parcel, referred to as the Calabrese parcel. This parcel was in the initial stages of development for a senior housing complex when industrial wastes were encountered during soil excavations for the concrete footings. The construction project was ordered to stop until the extent and degree of contamination was identified. Following short-term actions to protect human health and the environment, EPA selected the site’s long-term remedy in November 2013. Design of the site’s remedy is underway.
What Is Being Done to Clean Up the Site?
The site is being addressed through federal and state actions.
What Is the Current Site Status?
The site’s long-term remedy includes limited targeted removal of contaminated soils, a pre-design investigation to better understand and address contaminated soils on certain parcels, a protective cap at the Calabrese Parcel, and the implementation of environmental land use restrictions across the site. Design of the site’s remedy is underway.
EPA’s Involvement at the Site
The Scovill Manufacturing Company used the site as a landfill from 1919 to the mid-1970s for disposal of ash, cinders, demolition debris and other wastes generated by the company. In 1998, the 6.8-acre Calabrese Parcel, located at the northern end of the site, was in the initial stages of development when a number of capacitors, ash, cinder, and other waste materials were encountered at depths ranging between 8 and 20 feet. In 1998, CT DEEP removed 2,300 tons of PCB-contaminated soil and 18 capacitors from the Calabrese Parcel.
Emergency Response and Removal
Site cleanup has also included removal actions, or short-term cleanups, to address immediate threats to human health and the environment. In 1998, the Connecticut Department of Energy and Environmental Protection (CTDEEP) removed 2,300 tons of contaminated soil and 18 capacitors from the Calabrese Parcel.
During cleanup, a site can be divided into a number of distinct areas depending on its complexity. These areas, called operable units (OUs), may address geographic areas, specific problems, or areas where a specific action is required. Examples of typical operable units include construction of a groundwater pump and treatment system or construction of a cap over a landfill.
