The history of drinking water chlorination

In the early 1900s, life was very different in the United States. Waterborne diseases like typhoid fever and dysentery were a common part of life—and a common cause of death, too.

But that all changed with a single significant advancement in public health: the introduction of chlorine in drinking water. We have Dr. John L. Leal to thank for this. His courage and persistence improved public health in our country and all over the world.

We hope you’ll enjoy learning more about this exciting achievement with the following:
