The fix for parched western states: Recycled toilet water. If it’s perfectly safe to drink purified wastewater, why aren’t drought-plagued states drinking more of it?
If you were to drink improperly recycled toilet water, it could really hurt you — but probably not in the way you’re thinking. Advanced purification technology so thoroughly cleans wastewater of feces and other contaminants that it also strips out natural minerals, which the treatment facility then has to add back in. If it didn’t, that purified water would imperil you by sucking those minerals out of your body as it moves through your internal plumbing.
So if it’s perfectly safe to consume recycled toilet water, why aren’t Americans living in parched western states drinking more of it? A new report from researchers at the University of California, Los Angeles, and the Natural Resources Defense Council finds that seven western states that rely on the Colorado River are on average recycling just a quarter of their water, even as they fight each other and Indigenous tribes for access to the river amid worsening droughts. Populations are also booming in the Southwest, meaning there’s less water for more people.
