### PCE/TCE NORTHEAST CO NTAMINATION York, Nebraska York County

 **Site Location :**  The PCE/TCE Northeast Contamination site includes the northern portion of the c ity of York, Nebraska, which is an indus trial/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 volati l e organic compounds (VOC s), 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 a pproximately 2.5 miles.

 **Site Contamination/Contaminants:** The ground water plume is com prised of chlorinated solvents, including but not limited to : tetrachloroethene (PCE), trichloroethene (TCE), 1,1,1

- trichloroethene (1,1,1

- TCA) 1,1

- dichlo roethylene (1,1

- DCE) and 1,1,2

- trichloroethane (1,1,2

- TCA)

.

 **Potential Impacts on Surrounding Commu nity/Environment** **:** The York Municipal Water Supply System serves a population of approximately 8 ,080 . T he 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.

 **Respons e 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 s tate of Nebraska

.

 **Need f or NPL Listing:**  The s tate of Nebraska referred the site to the EPA because the site requires short term and long- term response action s 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 opti ons 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.]
