Even in the midst of its historic, ongoing drought, California used millions of gallons of water for hydraulic fracturing last year, according to state officials.
The state used nearly 70 million gallons of water to frack for oil and gas in 2014, Reuters reported last week. That amount is actually less than the 100 million gallons officials previously estimated the state uses for fracking operations every year.
Steven Bohlen, California’s oil and gas supervisor, noted to Reuters that not all water used for fracking operations is freshwater: some of it is produced water, which rises to the surface during the fracking process and can’t be used for drinking or irrigation. In all, Bohlen said, fracking uses the same amount of water as about 514 households each year.
