Mount Pleasant's air quality in South Carolina benefits from the Charleston metropolitan area's coastal position with the Cooper River and Charleston Harbour providing maritime ventilation. Vehicle emissions from US-17 and the Arthur Ravenel Jr. Bridge approach are the primary local sources, while the Atlantic coastal exposure and tidal estuary geography generally maintain moderate to good conditions across this rapidly growing Charleston East Cooper suburb.
