U.S. Senator Mark Udall says there is no reason to worry about the use of hydraulic fracturing to free up oil and gas deposits if it’s done properly.
Hydraulic fracturing, or fracking, involves injecting vast amounts of water and chemicals to open deeply buried gas formations.
People living near drilling areas have complained about water and air quality.
Udall says it’s a safe technology that has resulted in a lot of home-grown energy being produced.
