Paradox Valley

The Colorado River Desalination Plant

According to a High Country News article, the Paradox Valley in western Colorado was formed millions of years ago, when a huge dome of salt collapsed. Now, that salt remains and the waters of the Dolores River pick it up and carry it to the Colorado River, where it eventually degrades the water quality for downstream users. For nearly 50 years the Paradox Valley Unit, which is operated by the U.S. Bureau of Reclamation, has been treating the salt problem. According to the article, the unit treats nearly 200 gallons of brine every minute—this is seven times saltier than ocean water. The brine is then injected into a formation about 2.5 miles beneath the Earth’s surface. The formation, however, will eventually fill up rendering the unit useless. According to the HCN article, there are no obvious replacement options, and officials do not know how long they have left, but estimate 10 to 20 years.

The Paradox Valley in western Colorado got its name because the Dolores River bisects it, rather than running through it in the normal topographical fashion. The landscape is short on people, long on sagebrush and probably best known for the dramatic red cliffs that loom over travelers making the long drive from Telluride, Colorado, to Moab, Utah.

When it comes to addressing salinity levels in the Dolores River, it may be time to “think outside the well.” The Bureau of Reclamation is seeking public input on whether to continue using deep-well injection methods to reduce salinity loads where the river flows through the Paradox Valley, or to consider evaporative ponds.
