PFAs found at Salem-Willamette Valley Airport raise health concerns

Per- and polyfluoroalkyl substances, or PFAs, were found in the soil at a development site at the south end of the property in an area where the Salem Fire Department has done firefighting foam testing.

City officials want to determine whether the chemicals could be harmful to firefighting staff who train there.

The Environmental Protection Agency says PFAs have been linked to harmful health effects in people and animals.
