Air Quality

Most counties in New Hampshire took home high marks for air quality in this year’s “State of the Air” report from the American Lung Association.

Two counties do stand out, however, as lagging behind the rest of the state.

Hillsborough county saw an elevated number of days with high levels of ozone or smog, which is produced primarily by automobile and power plant emissions. The trend generally in Hillsborough county has been toward less smog.

A report shows that progress on air quality has stalled in New Hampshire.

The EPA is proposing stricter emissions standards for wood stoves.  Manufacturers would have to build stoves that burn 80 percent cleaner than current models.  And for the first time, pellet stoves would be held to the same standards.  The EPA says pollution from these heaters is linked to asthma attacks, heart attacks, and stroke. 

The Department of Environmental Services blames cold temperatures and low winds for poor air quality in the valleys of Southwestern New Hampshire, including Keene.
