New Britain's air quality reflects the Quinnipiac River valley in central Connecticut, with vehicle emissions from I-84 and the surrounding manufacturing legacy of this former hardware manufacturing capital contributing local sources. The Connecticut uplands create modest topographic variation, while the broader New England regional airshed contributes upwind urban and industrial sources from the New York and Hartford corridors on prevailing southwesterly winds throughout the year.
