What is the difference between EPA’s Removal Action at the site from 2020 to 2022 and the current Study Area?
EPA’s Removal Action from 2020 to 2022 was a quick response to immediate threats from hazardous substances at the former Erie Coke facility to eliminate dangers to the public. During this time, EPA’s Removal team focused on sampling surface soils, coal, and coke residuals for hazardous substances, removing and properly…

Could contaminants from the former coke facility leach into the groundwater from the soil?
There is low potential for drinking water contamination because no one in the surrounding community is using groundwater as a drinking water source. Drinking water intakes for the City of Erie are from Lake Erie miles out into the lake, far west of the site. The Pennsylvania Department of Environmental…

Why is EPA beginning a site investigation in 2024 when the Erie Coke facility existed for many decades in the past?
The Coke Facility was a permanent, operating facility from 1925 to 2019. The EPA Superfund Program does not investigate operating facilities. After the facility closed in 2019, the Pennsylvania Department of Environmental Protection (PADEP) requested assistance from EPA's Removal Program to conduct assessment activities at the Erie Coke Site. Based…
