Groundwater is a vital but often under-appreciated part of the freshwater hydrologic system. Almost 200 million North American residents rely on groundwater for domestic use. Groundwater is also vital to the agricultural and industrial sectors of the North American economy and plays an essential role in sustaining rivers, streams, lakes, wetlands, and aquatic systems. Important though it is, the groundwater resource is under threat — contamination of aquifers is pervasive in North America and in many places groundwater is being used faster than it is being replenished.
