Haverford's air quality reflects the Philadelphia metropolitan area's affluent Main Line position in Delaware County Pennsylvania, with vehicle emissions from US-30 Lancaster Avenue and I-476 the primary local sources in this major Philadelphia western suburb. The Schuylkill River corridor provides limited ventilation, while the broader Philadelphia mid-Atlantic regional airshed contributes summer ozone and the surrounding suburban parkland character maintains relatively lower local emission density than comparable urban areas throughout the year.
