The Zanesville Well Field Superfund Site is located on the banks of the Muskingum River in the center of Zanesville, Ohio. The property on the west side of the bank had been used for manufacturing purposes since 1893, when American Encaustic Tiling Company was a ceramic products manufacturer. United Technologies Automotive was the source of the contamination and retained the liability for the site. Unknown waste storage and disposal practices occurred. However prior to 1929, a well was installed on the property. The well fell into disuse and in the 1970's the well was filled to prevent it from being a safety hazard.
Rubble from the demolition of the well pump house along with some 120 steel drums was used to fill the well. The drums contained trichloroethylene-based solvents. TCE is a chemical commonly used as a solvent and in pharmaceuticals. It can be toxic to humans. The remaining fragments of these drums and debris were removed and closed 1983.
In 1981, EPA detected contamination at the Zanesville Municipal Well Field. As a result of additional sampling of the well field, three wells in the southern portion of the well field were found to be contaminated with TCE. An investigation of contamination problems at the site was concluded in September 1990. There were elevated levels of TCE. There were no detectable concentrations of contaminants in any of the wells sampled in the municipal well field that were in use at the time.
The Record of Decision for the cleanup design was approved in 1991. It included containment and capture of contaminated groundwater, restoration of the aquifer, treatment of contaminated groundwater, treatment of soil contaminated with inorganic compounds by soil washing, and treatment of soil and source areas contaminated with VOCs by in-situ soil vapor extraction. The groundwater remediation system design was based on the results of groundwater modeling and historical performance of the interim design. Over 1,880 cubic yards of soil was removed and a total of 16 soil vapor extraction wells were constructed.

The U.S. Environmental Protection Agency completed a five-year review of the Zanesville Well Field Superfund site on Linden Avenue in Zanesville, Ohio. The Superfund law requires regular checkups of sites that have been cleaned up – with waste managed on-site – to make sure the cleanup continues to protect people and the environment. This was the third five-year review of this site. The review concluded that the remedy is functioning as intended and is protective of human health and the environment. A copy of the report is available below.
