Summerville's air quality reflects the flat South Carolina Lowcountry terrain north of Charleston, with vehicle emissions from I-26 and US-17 and the surrounding Joint Base Charleston's military aviation operations contributing elevated NOₓ alongside primary vehicle sources. The flat coastal plain provides generally good wind dispersal, while summer ozone from the broader southeastern US regional airshed is the primary warm-season concern and sea breezes from the Charleston harbour provide periodic ventilation.
