EPA assessing Superfund sites in Midwest flood zone
The Environmental Protection Agency said it is assessing two Superfund sites located in areas that have seen overwhelming floods in recent weeks.
The EPA identified the Superfund sites as the Nebraska Ordnance Plant in Mead, Nebraska, and the Conservation Chemical Corporation in Kansas City, Missouri.
At the Nebraska Ordnance Plant, floodwaters rendered portions of the site temporarily inaccessible. Shutdown of the groundwater treatment plant and extraction wells was necessary for approximately two days, due to access issues. The treatment plant and all wells are up and running again.
Conservation Chemical Corporation partially flooded when the Missouri River topped its bank near the site. In response, the site’s Potentially Responsible Parties, under EPA oversight, successfully increased the pumping rate of the groundwater treatment system to account for impacts from floodwaters.
Superfund is a law that gives the EPA funding and authority to clean up contaminated sites.
The agency said it has not found evidence that any hazardous contaminants were released by the flooding.
The EPA said it will continue monitoring the potential impacts of the floods. Additional actions may include sampling and site inspections, among others, to ensure that installed remedies remain operational.
