North Charleston's air quality reflects its position as South Carolina's industrial hub, with the Boeing facility, Port of Charleston, and Joint Base Charleston military operations generating concentrated industrial and aviation emissions. The Cooper and Ashley river corridors provide some maritime ventilation, while the industrial concentration makes North Charleston markedly more polluted than the historic Charleston peninsula.
