Bentonville's air quality benefits from the flat Ozark plateau in northwest Arkansas providing generally good wind dispersal, with vehicle emissions from I-49 the primary local source in the Walmart corporate headquarters city. The broader Northwest Arkansas technology and retail corridor generates moderate vehicle traffic, while the Ozark plateau's elevation and the surrounding forest provide a relatively clean rural backdrop and summer ozone from the regional airshed is the primary warm-season concern.
