A report shows that progress on air quality has stalled in New Hampshire.
The American Lung Association's State of the Air 2014 notes that new Hampshire's air quality has improved overall since the reports started 15 years ago.
But board member Rick Rumba says there's still a concern with regard to the increasing impact of small air pollution sources such as residential woodstoves and fireplaces. He says homeowners should be encouraged to burn wood more cleanly and efficiently, using lower-emitting, EPA-certified devices.
The report says Hillsborough County saw its grade for ozone drop from a C to a D — experiencing three additional days when the air was unhealthy. The county has the worst ozone pollution in New Hampshire. All other counties with monitors saw their ozone levels remain even.
