National Ground Water Association (NGWA) has organized this week-long event, devoted to raising the public's awareness of groundwater. Some facts gained by reading the NGWA's press release about the event are definitely worth sharing:
- 99% of all available freshwater in the world is groundwater, according to the USGS. That means all the world’s rivers, lakes, and streams make up only 1%.
- The USGS also reports that on average, 30% of all streamflow in the U.S. is from groundwater.
- Perhaps 90% of the population in rural areas would have no reliable water source if it weren’t for private household water wells that tap groundwater.
