1.1.1 Incident Category
CERCLA Incident Category: Time-Critical Removal Action
1.1.2 Site Description
1.1.2.1 Location
The city of York is located in the west-central portion of York County in southeast Nebraska. The Site is located to the southeast of the city of York, near the intersection of Road N and Road 12. Land use in the area is primarily residential.
1.1.2.2 Description of Threat
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
In conducting downgradient sampling pertaining to another Superfund site in the area (the PCE/TCE Northeast Contamination site, f.k.a. as the York Northeast Groundwater site), a distinct groundwater contaminant plume in York was discovered by the U.S. Environmental Protection Agency in the fall of 2010. As a result of this discovery, the EPA completed an Abbreviated Preliminary Assessment (APA) for the Site in November 2010. Sampling conducted during the preparation of the APA identified eight residential drinking wells with concentrations of PCE ranging from 9.6 to 32 micrograms per liter (mg/L). Of these wells, one also contained trichloroethene (TCE) at a concentration of 5.9 mg/L. The EPA’s maximum contaminant level (MCL) for both PCE and TCE is 5 micrograms/liter.
