What happens to hydraulic fracturing wastewater on cropland

The use of hydraulic fracturing, or "fracking," has grown rapidly in the U.S. over the past 15 years—but concerns persist that the oil and gas extraction method could harm the environment and people's health. To better understand its potential effects, scientists simulated what would happen to the wastewater produced by the technique after a spill. They published their findings in the ACS journal Environmental Science & Technology.
