***Proposed Site*** December 2013 

PCE/TCE NORTHEAST CONTAMINATION York, Nebraska 

York County 

 Site Location:

The PCE/TCE Northeast Contamination site includes the northern portion of the city of York, Nebraska, which is an 

industrial/urban residential area, and the rural residential area just outside of the northern portion of city limits.

 Site History:

The site is composed of documented releases of hazardous substances, mainly volatile organic compounds (VOCs), into 

soils and ground water. To date, one municipal water supply well has been impacted and taken off line due to 

contamination. The plume has also impacted six private residential water supply wells, which have required alternate water. 

The contamination appears to be coming from the Kroy/Alcan, Kroy Industries and Kroy Building Products facilities.

However, there may be additional source areas. The site ground water plume extends approximately 2.5 miles. 

 Site Contamination/Contaminants:

The ground water plume is comprised of chlorinated solvents, including but not limited to: tetrachloroethene (PCE), 

trichloroethene (TCE), 1,1,1-trichloroethene (1,1,1-TCA) 1,1-dichloroethylene (1,1-DCE) and 1,1,2-trichloroethane (1,1,2-

TCA). 

 Potential Impacts on Surrounding Community/Environment: 

The York Municipal Water Supply System serves a population of approximately 8,080. The site ground water plume 

extends approximately 2.5 miles. The new municipal public water supply well field is in danger of becoming contaminated 

because it is located less than 1/8 of a mile down-gradient of the ground water plume. Additionally, there are several private 

water supply wells in danger of becoming contaminated because they are also located down-gradient of the ground water 

plume. 

 Response Activities (to date):

There is an ongoing removal action at PCE/TCE Northeast Contamination site to provide alternate water to residences. To 

date, the EPA has provided alternate water to six 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.]
