Where does drinking water come from?

In Wisconsin, about 66% of people use groundwater as their drinking water source. Groundwater is part of the water cycle. When it rains or snows, water seeps into pores and cracks in the soil. It’s stored in a rock layer in the Earth called an aquifer. This water is supplied to people who live in Wisconsin through a private well or a public water system.

The other 33% of people get their drinking water from Lake Superior, Lake Michigan, or Lake Winnebago. This water is supplied to people through a public water system.
