The Environmental Protection Agency has ordered treatment of Portsmouth-owned wells at the Pease International Tradeport that have been tainted by "contaminants of emerging concern."
The Portsmouth Herald reports the order issued Wednesday requires the U.S. Air Force to design, install and operate a groundwater treatment system for the Haven well closed last year because of high levels of chemicals. A similar order was given to treat two neighboring wells with lower levels.
Air Force and EPA officials believe the contamination came from firefighting foam that was used on the base when it was an active military site.
Health officials have shipped blood samples they've received from people who were exposed to contaminated city water to the Centers for Disease Control and Prevention.
