San Joaquin Valley

The San Joaquin Valley is one of the world’s most productive agricultural regions and home to four million Californians. EPA is working with other agencies and local communities to address the unique environmental challenges in the valley, including some of the nation’s worst air quality, high rates of childhood asthma, and contaminated drinking water.
