NPL Site Narrative for PCE Southeast Contamination
PCE SOUTHEAST CONTAMINATION
The PCE Southeast Contamination site includes the central and southeastern portions of the city of York, Nebraska, which is an industrial/urban residential area, and the rural residential area just outside of the southeastern portion of city limits.
Preliminary Assessment and Site Inspection activities have been conducted at the site. The PCE Southeast Contamination site is a ground water plume. The site is composed of documented releases of hazardous substances, mainly volatile organic compounds (VOCs), into soils and ground water. There are many possible sources resulting from various operations such as dry cleaners, metal degreasing operations and grain storage facilities. To date, one municipal water supply well has been impacted and taken off line due to contamination. The plume has also impacted 3 private residential water supply wells, which have required alternate water.
The ground water plume is comprised of chlorinated solvents, including but not limited to: tetrachloroethene (PCE), trichloroethene (TCE), and degradation products.
Potential Impacts on Surrounding Community/Environment:
The ground water plume extends approximately 2.0 miles. There are several private water supply wells and irrigation wells in danger of becoming contaminated because they are located down-gradient of the ground water plume. Ground water is a precious natural resource that the State of Nebraska wants protected.
Response Activities (to date):
There is an ongoing removal action at PCE Southeast Contamination site to provide alternate water to impacted residences. To date, the EPA has provided alternate water to three residences at the request of the state of Nebraska.
Need for NPL Listing:
The state of Nebraska referred the site to the EPA because the site requires short-term and long-term response actions and listing will allow for a proper and timely investigation of the nature and extent of contamination and remediation of the site. Other federal and state cleanup programs were evaluated, but are not viable options at this time. The EPA received a letter of support for placing this site on the NPL from the state.
[The description of the site (release) is based on information available at the time the site was evaluated with the HRS. The description may change as additional information is gathered on the sources and extent of contamination. See 56 FR 5600, February 11, 1991, or subsequent FR notices.]
