Studying the Cycling of Water through the Soil

Annually, more than 375 trillion gallons of water seep into the soil to be filtered before recharging the groundwater. 375,000,000,000,000 gallons of water… how much is that? A swimming pool the size of North Carolina would have to be 450 feet deep to hold all of the water.

Protecting this essential resource is a one of the many jobs soil scientists perform everyday.
