Report finds toxic chemicals at Burlington air base exceed state limits

The Air Force has released a report detailing chemical contaminants at the Burlington International Airport above Vermont regulatory limits.

These chemicals were found at multiple locations on the Vermont National Guard installation, but not in the base's drinking water, or the water supply of nearby communities. Now, the Air Force is continuing the investigation, along with the Vermont Department of Environmental Conservation, to determine the extent of the contamination.

The chemicals, known as PFOA and PFOS are present in fire retardant and have been in the news recently after the U.S. Environmental Protection Agency kept a report on them secret from the public. They've been linked to a number of serious health problems.
