This week marks National Groundwater Awareness week, so I wanted to talk about groundwater in general, and some groundwater facts for Round Rock.
- Groundwater is the water that soaks into the soil from rain or other precipitation and moves downward to fill cracks and other openings in beds of rocks and sand. It is, therefore, a renewable resource, although renewal rates vary greatly according to environmental conditions.
- It also is an abundant natural resource.
- Of all the freshwater in the world (excluding polar ice caps), 95 percent is groundwater. Surface water (lakes and rivers) only make up three percent of our freshwater.
