Amount of water withdrawals in America in a DAY! Image from http://ga.water.usgs.gov/edu/wusw.html


Water is a major concern throughout the world because the earth has a tiny percentage of usable water. The water that we use in America are mostly stored in aquifers and surface water. Aquifers are huge surfaces of underground water that can be extracted for use. Studies proved that aquifers are depleting rapidly due to our excessive usage. Taking out more water than putting it in is known as drawdown, which would lead to droughts.

If there is no more water in our aquifers, then we would be forced to drain surface water at a dangerous rate that can influence landforms. If that does happen in Colorado, then the Rocky Mountain rivers would be a significant source of freshwater fueling most of the state. But other bodies of surface water would also be affected as well, such as lakes and reservoirs. This would mean Cherry Creek Reservoir would be at risk of becoming dry. The reservoir is in the middle of a high population community, it would be the main source of freshwater for Aurora to Denver.

One solution that I thought of is to capture fresh glacier water and ice for our needs in order to decrease the high volume of ground and surface water usage.
