Overview

Air Quality in San Antonio

San Antonio is a big city blessed with a warm climate, robust economy and growing population. But, like all big cities, those blessings also present challenges that may threaten our collective well-being. One of those challenges is keeping our air clean – the air that we breathe every day and on which all life depends. Our air doesn’t look particularly dirty, but the truth is we have surpassed the U.S. Environmental Protection Agency’s (EPA) health-based clean air standards. Therefore, it’s important for us all to work together to reduce pollution and clean up our air.
