Thinking About Technology During Drinking Water Week

By Katie Henderson

This week is national Drinking Water Week, and it’s a good time to highlight drinking water technology, a critical component to safe drinking water in the United States.

A few years ago, my husband and I went camping in Montana. My husband likes to find ingenious gadgets and gear for outdoor recreation. Right before the trip he had bought a portable water sterilization gadget that uses ultraviolet (UV) light to purify water. We decided to give it a try during our hike. I have to admit, it seemed a little like science fiction! Of course, this little gadget only had to treat a liter of water. The average American household uses about 1100 liters of water every day. Public water systems must meet nearly 100 different standards to deliver safe water using a variety of technologies, including UV treatment.

I continue to marvel at the improvement of water technology over the last century. Public health experts say that water technology improvements – like chlorine treatment and filtration – are some of the most important public health innovations of the last century. One hundred years ago, waterborne diseases like typhoid, cholera, and dysentery were much more common. They are very rare in the U.S. today thanks, in a large part, to drinking water technology.

This year is the 40th anniversary of the Safe Drinking Water Act (SDWA), which requires EPA to establish national standards for drinking water quality and treatment for all public water systems. Public water systems must comply with SDWA as they treat and monitor your water, maintain the system’s infrastructure and equipment, and keep consumers informed. The little UV gadget we used on our camping trip is a tiny version of the sophisticated processes involved in delivering your drinking water.
