Collierville's air quality reflects the flat suburban Shelby County position east of Memphis in the Tennessee-Mississippi border region, with vehicle emissions from US-72 and the surrounding affluent residential and commercial character contributing local sources. The broader Memphis regional ozone from vehicle sources is the primary warm-season concern, while the flat terrain and consistent Gulf South winds generally maintain moderate conditions and Collierville's planned community character limits heavy industrial emissions throughout the year.
