Groundwater: A Global Emergency
Groundwater is the most abundant source of liquid freshwater on the planet. Aquifers hold at least 25 times the water as rivers, lakes, and streams. Roughly two billion people rely on groundwater as a primary source of drinking water and nearly half the water used to irrigate crops comes from underground.
Yet despite its importance, groundwater is being used recklessly.
