One of my first recollections of Kansas City was sitting at a stoplight while fierce gusts of wind attacked my car and shook traffic signal poles so viciously that I thought they would snap like popsicle sticks. Actually, it wasn’t just the wind but also the ragweed that was assaulting my car and senses. I am violently allergic to ragweed and the stuff grows…well like weeds out here.

My allergies notwithstanding, we have pretty good air quality throughout the Midwest although we do face challenges with ozone and particulate matter in urban areas like Kansas City and St. Louis. Throughout the country, states, tribes, and local governments maintain monitors that sample for pollutants. Since these monitors play an important role in revealing air quality, they must be operated and maintained properly. We assist by auditing stations to ensure that equipment is operating properly. This work requires a platform that can house delicate instruments yet is rugged enough drive to remote locations. After several possibilities we settled on a Winnebago, but there is nothing recreational about this vehicle.

We designed it to operate as a mobile air monitoring laboratory. We’ve used this platform successfully for a number of years and it serves as a great conversation piece when we talk with children about air quality. On-site audits require several hours to complete and we use a gasoline generator to power the instruments. Sometime last year the guys got the idea of supplementing the lab with the abundant source of clean energy that was howling in their ears… wind.

Several weeks ago we installed a turbine to harness the clean energy provided by the wind. The turbine generates electricity to recharge batteries stored inside the lab that when fully charged can run the entire lab for up to eight hours without a single wisp of generator exhaust. Thanks to this innovation we will conserve gasoline on each trip (as long as the wind cooperates). As my old high school football coach Sherman Smith used to say… if it’s to be it’s up to me. We know that it is up to all of us to find ways to help reduce our carbon footprint both at home and where we work, even if work is sometimes on a dusty road in western Nebraska. Now if we could just find something to use all that ragweed for…

Movies require you to suspend your disbelief, but when you watch a film that hits close to home it can be tough. I have a friend in federal law enforcement who squirms when cardboard cutout agents run across the screen. Action flicks don’t do his profession justice, but at least his job is sometimes glorified on celluloid. The only two movies I can remember featuring a prominent EPA employee are Ghostbusters and the Simpsons Movie, neither of which ever made a kid say, “Man, when I grow up I want to work for the EPA.” On the off-chance your youngster was inspired to seek out public service please let them know we don’t inspect unlicensed nuclear storage facilities, nor do we have a fleet of helicopters. We do however, have one cool plane.

EPA’s Airborne Spectral Photometric Collection Technology, known as ASPECT, is an aircraft equipped with sensors that allow for surveillance of gaseous chemical releases from a safe distance. ASPECT gives emergency responders information regarding the shape, composition and concentration of gas plumes from disasters such as a derailed train, factory explosion or terrorist attack.

This was the scene in Kansas City outside our office windows in 2007 when a chemical facility went up in flames. ASPECT deployed and was instrumental in verifying that while ominous, the fire did not present a significant health threat to the community (the white signature you see below is the fire).

Since its inception ASPECT has flown over several fires, provided support during the Olympics and Columbia shuttle recovery, and supplied some of the first aerial images of the devastation along the coast during Katrina.

Most of the technology you see in movies is sheer fantasy, but EPA’s high-tech plane and the scientists who operate it are worthy of a spot in the next summer blockbuster. Here’s hoping for the appearance of an EPA scientist who isn’t a bad guy (although with my face the best I could hope for is Thug #4 in the next straight to DVD clunker).
