Georgetown's air quality reflects its position in Williamson County along the San Gabriel River, at the northern edge of the Austin metropolitan area, with vehicle emissions from I-35 and the rapidly growing suburban corridor contributing local sources. The rolling Hill Country terrain provides moderate wind dispersal, while summer regional ozone from the broader Austin metropolitan area is the primary warm-season concern throughout the year.
