Fracking operations in the U.S. have gotten thirstier in the last 15 years, consuming more than 28 times the water they did a mere 15 years ago.
A new study by the U.S. Geological Survey (USGS), in partnership with the American Geophysical Union, shows that not only has the number of such operations grown as fracking has expanded its reach and improved technology has allowed drilling in harder to reach locations, but individual wells are consuming more water as well. The median amount of water consumed by a single fracked well grew from 177,000 per oil and gas well in 2000 to more than 4 million gallons per oil well and 5.1 gallons per gas well in 2004. That's far more than the 671,000 gallons a year used by a conventional or vertical well. In the 52 out of 57 watersheds with the highest average water use, more than 90 percent of the wells were involved in horizontal drilling in shale gas areas.
Water consumption within a watershed where fracking takes place varied considerably, depending on the geology of the region and the location of the oil or gas deposit. Some operations in southern Illinois used as little as 2,600 gallons per well, while others in Pennsylvania, Ohio, Montana, Colorado, Arkansas and Texas used as much as 9 million gallons.
"One of the most important things we found was that the amount of water used per well varies quite a bit, even within a single oil and gas basin," said USGS scientist Tanya Gallegos, the study’s lead author. "This is important for land and resource managers, because a better understanding of the volumes of water injected for hydraulic fracturing could be a key to understanding the potential for some environmental impacts."
According to study co-author Mark Engle, the increase is due to the same improved technology that allows companies to reach more out-of-the-way deposits. Fracturing the rock formations in those areas to allow access to the gas or oil requires more fluid to be injected under pressure.
The study compiled data on the amount of water used in more than 263,859 oil and gas wells drilled between 2000 and 2014 to create the first ever map depicting how and where hydraulic fracturing operations use water. The shale formations that coincided with watersheds where the most water was used for fracking operations including Eagle Ford and Barnett with watersheds located in Texas, Haynesville-Bossier above watersheds in Texas and Louisiana, Arkansas' Fayetteville, Oklahoma's Woodford, Tuscaloosa with watersheds located mainly in Louisiana and Mississippi, and the eastern Marcellus and Utica shale plays with watersheds in parts of Ohio, Pennsylvania, West Virginia and New York.
Many of those areas have also experienced damaging droughts in the last five years due to climate change-driven global warming. So while the amount of water used in fracking is small compared to other uses such as agriculture, "The reality is there is a pretty strong constraint on the amount of fresh water available,” said Engle.
Some of the water used in drilling operations is recycled. But most of it, laden with toxic chemicals, is injected into deep underground wells where it is removed from future reuse. And, injecting fracking wastewater into underground wells has created another issues for many of these states—earthquakes.
"This research was carried out as part of a larger effort by the USGS to understand the resource requirements and potential environmental impacts of unconventional oil and gas development," says the governmental organization.
And if understanding leads to banning, as it did in New York recently, environmental advocates will cheer.

Here are three new films to watch this Earth Week that will transport you from pole to pole and introduce you to the scientists and activists working to save our shared home.
1. The Year Earth Changed
Where to Watch: Apple TV+
When to Watch: From April 16
The coronavirus pandemic has brought home the stakes of humanity's impact on the environment. But the lockdowns also proved how quickly nature can recover when humans give it the space. Birds sang in empty cities, whales surfaced in Glacier Bay and capybara roamed the South American suburbs.
The Year Earth Changed captures this unique year with footage from more than 30 lockdowned cities between May 2020 to January 2021. Narrated by renowned wildlife broadcaster David Attenborough, the film explores what positive lessons we can take from the experience of a quieter, less trafficked world.
"What the film shows is that the natural world can bounce back remarkably quickly when we take a step back and reduce our impact as we did during lockdown," executive producer Alice Keens-Soper of BBC Studios Natural History Unit told EcoWatch. "If we are willing to make even small changes to our habits, the natural world can flourish. We need to learn how to co-exist with nature and understand that we are not separate from it- for example if we closed some of our beaches at for a few weeks during the turtle breeding we see that it can make a huge difference to their success. There are many ways that we can adapt our behavior to allow the natural world to thrive as it did in lockdown."
2. After Antarctica
Where to Watch: San Francisco International Film Festival
When to Watch: 12 a.m. PST April 9 to 11:59 p.m. April 18
In 1989, Will Steger led an international team of six scientists and explorers to be the first humans to cross Antarctica by dogsled. Steger and his team weren't just in it for the adventure. They also wanted to draw attention to the ways in which the climate crisis was already transforming the icy continent and to rally support for the renewal of the Antarctic Treaty, which would keep the continent safe from extractive industries.
In After Antarctica, award-winning filmmaker Tasha Van Zandt follows Steger 30 years later as he travels the Arctic this time, reflecting on his original journey and once again bringing awareness to changes in a polar landscape. The film intersperses this contemporary journey with footage from the original expedition, some of which has never been seen before.
"Will's life journey as an explorer and climate activist has led him not only to see more of the polar world than anyone else alive today, but to being an eyewitness to the changes occurring across both poles," Van Zandt told EcoWatch. "But now, these changes are happening in all of our own backyards and we have all become eyewitnesses. Through my journey with Will, I have learned that although we cannot always control change, we can change our response. I feel strongly that this is a message that resonates when we look at the current state of the world, as we each have power and control over how we choose to respond to hardships, and we all have the power to unite with others through collective action around a common goal."
After Antarctica is available to stream once you purchase a ticket to the San Francisco International Film Festival. If you miss it this weekend, it will screen again at the Minneapolis St. Paul International Film Festival from May 13 to May 23.

3. The Race to Save the World
Where to Watch: Virtual Cinema
When to Watch: From Earth Day, April 22
While many films about the climate crisis seek to raise awareness about the extent of the problem, The Race to Save the World focuses on the people who are trying to stop it. The film tells the story of climate activists ranging from 15-year-old Aji to 72-year-old Miriam who are working to create a sustainable future. It follows them from the streets to the courtroom to their homes, and explores the impact of their advocacy on their personal lives and relationships.
Emmy award-winning documentary filmmaker Joe Gantz told EcoWatch that he wanted to make a film about climate change, but did not want to depress viewers with overwhelming statistics. Instead, he chose to inspire them by sharing the stories of people trying to make a difference.
"Unless millions of people take to the streets and make their voices heard for a livable future, the politicians are not going to get on board to help make the changes needed for a sustainable future," Gantz told Ecowatch. "I think that The Race To Save The World will energize and inspire people to take action so that future generations, as well as the plants, animals and ecosystems, can survive and thrive on this planet."
Check back with EcoWatch on the morning of Earth Day for a special preview of this inspiring film!
