GAINESVILLE, Florida (Oct. 15, 2026) – U.S. Environmental Protection Agency (EPA) will hold an open house on Wednesday, Oct. 21 from 5 – 7 p.m. at the Cabot/Koppers Superfund Site, 200 NW 23rd Avenue in Gainesville, Florida, to share an update on cleanup activities, including installation of a 5,300-foot wall extending 65 feet below ground to help prevent contaminated groundwater and soil from spreading.
Additional actions, planned in coordination with local, state, and federal partners, include:
Replacing existing stormwater ditch with a new piping system configured to avoid the groundwater cut-off wall.
Removing contaminated soil piles, surface soil, and ditch sediments from former Municipal Storage Yard and relocating them inside the cut-off wall.
Background
The Cabot/Koppers Superfund Site encompasses 140 acres in Gainesville, Florida. The Cabot portion of the site operated as a pine-tar products facility from 1910 until 1967 and has been redeveloped into commercial properties. Cleanup on this portion is mostly complete and includes a separate cut-off wall to prevent contaminated water and soil from leaking out. The Koppers site operated as a wood treatment facility from 1916 until 2009. This site is owned by Beazer East, Inc. and is undergoing cleanup. Under a consent decree with EPA, Beazer East has certain cleanup responsibilities for a portion of the site.
