WSJ piece noting that all this hydralic fracturing (fracking) is coming up against local water limits. Already, US fracking uses water on par with the city of Chicago or Houston.
So the industry jumps into figuring out how to reuse the water multiple times by cleaning it up (not enough for drinking but enough to reuse). Already in PA the percentage use of recycled water is up to 17% this year, jumping from 13% last year.
This is a huge issue, because we're looking at 1 million more fracking wells globally by 2035, according to Schlumberger (oilfield services co.). The issue is expressed both in unwanted externalities (enviro risks/damage) and cost within the industry (acquiring and disposing).
Something to keep an eye on, as the industry competes with Mother Nature (climate change), agriculture and urbanization globally.
