Denver may be America's newest, favoritist city, but there's something foul in the air here. And no, this is not a 4/20 post, though that happens to be today's date.

A survey by the American Lung Association just scored the Denver metro area at no. 8 on the list of worst ozone pollution. We trailed six Southern California areas and Phoenix, showing once again that this is a Sunbelt problem. Denver's air was less than half as bad as California's worst, measured in ozone alert days.

The worst ozone problem in Colorado occurs in Jefferson County, where I live. On summer days, high-level westerly west winds overhead create a breeze out of the east, sort of like an eddy in a stream. That picks up pollutants from a 600-square-mile metro area and pushes them against the 1200' foothills of the mountains, where they bake in the strong sun and concentrate further. The result: Jefferson County had 103 days per year when some level or ozone alert is called; Denver had 23.

None of this is intuitively obvious. A visitor or immigrant would never notice. When I moved out of downtown Denver 15 years ago, I didn't expect to face four times the ozone alerts out in the suburbs, but that's what happened. I've always loved the western suburbs of Denver above all others, for their central location, mountain access, lower traffic and density. But maybe I've been making a mistake. Yes, I have asthma, and reduced lung function. This could be one reason why. All I can do is share what I know, and, unfortunately, I learned this something today.

Very interesting! I to would have thought the air would be better as I always think the prevailing winds are from the west as opposed to headed toward the west.

Do you have a link for the details you provided? I would like to read more.

I hope you realize that Colorado | American Lung Association has a HUGE agenda here. They want to raise money.

Really, Dave Barnes? Your implication is that the data is false, or biased, because they want to raise money? Can you provide some evidence of this?

I live on Lookout Mtn, which is Jeffco but provides a downslope view of the murky brown cloud that often hangs over the city. I was hopeful that the air up here (a couple of thousand feet higher than Denver) is cleaner, but maybe I have been fooling myself. I have noticed an uptick in my mild asthma lately.

I'll console myself that it is all just "propaganda" from the American Lung Association. Sheesh.

Agree with you, Nele -- I can see the cloud when I drive into Denver on the 36. I have also had trouble breathing since I arrived so maybe it is not just the altitude.

You must not have been in the Denver area in the 80s. Smog so bad that, from Sixth and Union at Green Mountain, my coworkers and I sometimes could not even see Denver AT ALL. It was completely Brown Clouded. At that time, the Brown Cloud crept to Sheridan. Later, population growth and traffic expanded the smog all the way INTO the foothills. On a few days, we even noticed it almost to Conifer.

This is no surprise whatsoever given the huge growth bubble.

Coming from CO Springs, that was one noticeable difference, the brown cloud... CO Springs never has that. It was really noticeable for me once you hit I-25 and 6th. The geography, the bowl shape, plays a part.

I do know my sources. I hate ALEC.
The references in the articles are worth looking at.
Both sides are exaggerating to make their points.

I have a problem with giving Denver an F.
Is Denver's air quality equal to Houston? Don't think so.
