From the Denver Business Journal (Cathy Proctor):
“In 2010, it reflected slightly less than one-tenth of one percent of the total water used [statewide],” says a report from the Colorado Oil & Gas Conservation Commission (COGCC). “In 2015, it is projected to increase by 4,800 acre feet to slightly more than one-tenth of one percent.”
Meanwhile, most oil and gas operators in Colorado are reporting hydraulic fracturing chemicals to the state, according to this report from Cathy Proctor writing for the Denver Business Journal. From the article:
The Colorado Oil & Gas Association (COGA) launched a voluntary water-testing program in January for any energy company that’s drilling in Colorado. It has signed up companies that are drilling 93 percent of all the oil and gas wells being worked in Colorado every year, said Tisha Schuller, COGA’s president and CEO. “And it’s expanding. We think that everyone [drilling in Colorado] should be in this program,” she [said].
