Groundwater Data for the Nation
The USGS National Water Information System (NWIS) contains extensive water data for the nation.
Groundwater is one of our most valuable resources—even though you probably never see it or even realize it is there. There is water somewhere beneath your feet no matter where on Earth you live. Groundwater starts as precipitation, just as surface water does, and once water penetrates the ground, it continues moving, sometimes quickly and sometimes very slowly. Eventually groundwater emerges back to the surface and continues to participate in the global water cycle.

View Media DetailsThe Magic of GroundwaterThese kids probably think there is some kind of magic happening here ... they pull down a lever and out of the ground below their feet comes clear, cool freshwater. They (and maybe you) may not realize that there is an immense amount of water in aquifers below the earth's surface. In fact, there is a over a thousand times more water in the ground than is in all the world's rivers and lakes. Groundwater Basics
