The American Lung Association's massive

report for 2014 is out, with the organization grading places all over the country in terms of air pollution, including Colorado.

Ozone-pollution figures for fourteen Colorado counties were available, and the ALA's judgments are harsh: Eight of the counties get grades of "D" or "F," with only two earning an "A." We ranked the photo-illustrated results, using data in other categories as tiebreakers and giving extra credit for providing data even if the scores are iffy. Count them down below.

Number 9: Jefferson County Number 8: Weld County Number 7 (tie): Douglas County Continue to keep counting down the (mostly lousy) ozone pollution grades of nine Colorado counties. Number 7 (tie): Arapahoe County Number 6 (tie): Denver County Number 6 (tie): Boulder County Continue to keep counting down the (mostly lousy) ozone pollution grades of nine Colorado counties. Number 6 (tie): Adams County Number 5 (tie): El Paso County Number 5 (tie): La Plata County Continue to keep counting down the (mostly lousy) ozone pollution grades of nine Colorado counties. Number 4: Rio Blanco County Number 3 (tie): Gunnison County Number 3 (tie): Garfield County Continue to keep counting down the (mostly lousy) ozone pollution grades of nine Colorado counties. Number 2: Pitkin County Number 1: Mesa County

Here's the complete State of the Air 2014 report.
