Centreville's air quality reflects the Northern Virginia suburban corridor in Fairfax County, with vehicle emissions from US-29 and I-66 and the surrounding government contractor and commercial character contributing concentrated commuter NOₓ. The Washington DC metropolitan airshed contributes regional ozone, while the flat Piedmont terrain provides reasonable dispersal and Centreville's position near the Dulles Airport corridor adds localised aviation emissions on approach flight paths throughout the year.
