Contaminated: Dirty Water In California's San Joaquin Valley

Feb 14, 2018

In 2012, California made history when it became the first U.S. state to declare that clean drinking water is a human right. But five years later, nearly 300 communities still shouldn’t drink their water, according to new state data—and more than half of the 400,000 impacted residents live in the San Joaquin Valley.

In this series, our reporters visit these communities, speak with residents, and explore the challenges to obtaining safe, clean drinking water.
