Much of the water used for irrigation, drinking, swimming pools, and misters in the Southwestern states comes from the Colorado river. So much water, in fact, is diverted from the Colorado that it no longer, and has not for many years, reaches it's own outlet, instead running dry someplace in the desert. The water diverted from the river is carried hundreds of miles through the desert in largely open-air aqueducts, a practice that can mean the loss of more than 60% of the water due to evaporation in the desert heat. That water is essential to our survival is a non-issue. So is the fact that it is a finite resource. For a country that bothers to advocate water conservation in the home to school children with concepts like turning off the water when brushing your teeth, the denial of the Arizona aqueduct as a problem seems like a massive amount of denial. Water, not oil, is the major resource issue of the 21st century. It's time we started acting like it.
Where does your water come from? How long will it last?
