Abstract

Imagine drinking water that has dripped through the sponge you’ve just used to clean the breakfast dishes. This is what is happening around the world. Rain and snow pass through soil polluted with pesticides, poisonous metals, and radionuclides into the underground lakes and streams that supply rivers, lakes and drinking water. We need to understand this system better to protect our groundwater and, by extension, our drinking water. That's where Pacific Northwest National Laboratory comes in.
