Second Five-Year Review to Begin, Cleburn Street Well Superfund Site, Grand Island, Hall County, Nebraska
The U.S. Environmental Protection Agency (EPA) conducts regular checkups, called five-year reviews, on Superfund sites where cleanups are in progress or have been completed. These reviews are required by the Superfund law [42 U.S.C. Section 9621 (c)]. EPA Region 7 has initiated the second five-year review of the Cleburn Street Well Superfund Site in Grand Island, Hall County, Nebraska.
In 1986, tetrachloroethylene (PCE) contamination was discovered in a public water supply well known as the Cleburn Street well. The well was disconnected from the public water supply and studies were initiated to find the source of the contamination.
EPA investigations found the primary source of contamination in the Cleburn Street well was from a former dry cleaning facility. PCE is a solvent commonly used in dry cleaning operations. EPA investigations also found other sources of ground water contamination, but these sources were not associated with the contamination of the Cleburn Street well.
Since the late 1990s, various cleanups have been done by EPA, the state, and private parties to address ground water and soil contamination at each of the source areas.
At the source of the primary contamination:
- A soil vapor extraction system was installed to treat the contaminated soil.
- An extraction and treatment system was installed to address the contaminated ground water.
At two other source areas, ground water monitoring was started. For the remaining source area, soil vapor extraction was used to treat the contaminated soil, and pressurized air injection was used to clean up the ground water.
During the review, EPA studies site information and inspects the site to make sure the treatment systems are operating properly and continue to be protective of human health and the environment. We encourage the community to tell us about site conditions or concerns you may have.
A final report will be prepared at the end of the five-year review and will be available at the site information repositories. This is expected to be available to the public in June 2008.
