COLUMBUS, Ohio – The water footprint of hydraulic fracturing is increasing in Ohio and around the nation, according to new findings from the U.S. Geological Survey.

A USGS report found an average horizontal gas well consumed more than 5 million gallons of water in 2014, up from around 177,000 gallons in 2000.

Melanie Houston, director of water policy and environmental health with the advocacy group Ohio Environmental Council, says the fracking of Marcellus and Utica shale formations in Ohio put the state at the higher end of the spectrum of water use.

"It's needed to be used at a higher percentage in the fracking fluids that are created, so unfortunately that means that we're going to be tapping lots of different water resources from reservoirs and lakes to municipal water supplies to small streams and tributaries to feed this industry," she explains.

Houston says there are concerns about potential contamination, as the water used in fracking is combined with chemicals and is disposed into deep underground injection wells. But some well operators are working to capture and clean post-fracking water for reuse.

Ted Auch, Great Lakes program coordinator at FracTracker Alliance, says he's not surprised by the findings because his research found that fracking has used up to 7 percent of available water from the Muskingum Watershed.

He says he's troubled because the number is likely to exceed 10 percent in the next two years.

"In good years when it's raining cats and dogs like it is right now, there is excess water,” he states. “But that excess water buffers that watershed against drought in subsequent years.

“If you keep pulling water out and putting it down in the geology underneath, you are really compromising the integrity of that watershed."

The length of drilling wells is expected to increase, which Auch contends along with inadequate pricing of water will also deplete the resource.

"There's no incentive to use less water,” he points out. “As a matter of fact, there's an incentive to ramp up water demand when your number resource is priced so cheaply relative to its real cost."

Some in the industry say fracking uses significantly less water than many other processes, and the increased recycling and reuse of water will further reduce the use of water resources.

Minnesotans are preparing for another winter, and a new global study raises questions about how colder climates might see fewer days of ice cover on lakes.

The findings in the journal Nature Communications showed lakes in the Northern Hemisphere have seen ice melts happen sooner by an average of eight days, and the authors pointed to climate change.

Jerry Grundtner, president of the Forest Lake Lake Association, said recent ice-outs have varied, with some stretching into early May. But he added it is fair to think about the possibility of future issues.

"Earlier ice out means that vegetation has a more robust opportunity to grow more thick during the summer months," Grundtner explained. "It also allows, I think, the water temperature to increase to a higher temperature, which causes more algae."

Researchers at the University of Minnesota have also been sounding the alarm about the links between a warming climate and the conditions of northern lakes. A study from last year found oxygen levels in the world's freshwater lakes are declining at rates faster than in the oceans. And conservation groups say dry summers have fueled harmful algae growth on northern lakes.

As for earlier ice melts and the potential impact on lake recreation, Grundtner feels there is a double-edged sword. While fewer days of a frozen surface might shorten the ice-fishing season, he pointed out a longer ice-free season creates other concerns.

"There'll be a lot more recreational boat use on any lake if ice goes off earlier," Grundtner noted. "As more people use the lake, obviously, there's more of a detriment to the lake by heavy use. So, you know, I think there's an impact from a recreational standpoint also, on the water quality."

Groups like Minnesota Lakes and Rivers Advocates have called attention to the growing prevalence of larger watercraft and the powerful waves they create, impacting shorelines. Meanwhile, a separate, new study from a University of Arkansas researcher predicts a dramatic increase in fish kills as lakes experience rising temperatures.

Wildfires in Wyoming and across the West are creating bigger impacts on snowpack supplying farms, energy production and drinking water for millions of downstream users, according to a new study.

Steven Fassnacht, professor of snow hydrology at Colorado State University and the report's co-author, said the 2020 Mullen Fire in southern Wyoming and Cameron Peak Fire in Colorado were both very large fires destroying forests in places which have historically not seen fires spark or spread.

"They were burning at this high elevation where the snowpack is deep," Fassnacht observed. "They burned up there not because of a lack of snow; they burned because of a lack of rain in the summer."

Researchers found snow in wildfire-burned locations is now melting roughly three weeks earlier than normal, and Fassnacht explained as climate change expands fire zones into more snow areas, water managers and others may need to make adjustments. Increasing storage capacity can help capture melting snowpack, and managers can also re-time water releases from reservoirs to be in sync with time-sensitive users including farms.

Instead of less-than-precise tools such as snow courses and SNOTEL stations to estimate annual water supplies, Fassnacht urged managers to tap technologies including LIDAR, which works like radar using light instead of radio waves to measure snowpack, and new modeling, which can better calculate actual water volumes.

"We need to use multiple tools from our toolbox to better manage the water," Fassnacht emphasized. "One is the storage, and two is the information of how much is there, and how much is actually coming into the system?"

After the Cameron Peak fire, the city of Fort Collins was forced to cut off water coming down the mountain because it was filled with ash and soot. Wildfires also can increase landslides in watersheds, which Fassnacht pointed out can harm fish habitat and water quality for downstream users.

"Especially municipalities, especially for residential water use downstream of any of these fires," Fassnacht asserted. "The ash is very difficult to treat in water treatment plants."

A new film is documenting efforts to prevent invasive carp species from entering the Great Lakes.

"Against the Current 2: Keeping Invasive Carp Out of the Great Lakes" is a sequel to 2020's "Against the Current," which detailed work on the Brandon Road Lock and Dam project near Chicago.

Marc Smith, policy director for the National Wildlife Federation, said although the effort has been centered on Illinois and Lake Michigan, it has wide-reaching implications. He cautioned any of the Great Lakes could be vulnerable to invasive species of any kind, not just carp.

Smith described how carp could affect waterways such as Lake Erie.

"Carp would eat a lot of the forage food that a lot of the prey fish rely upon," Smith explained. "In some instances, perch can be impacted and that not only means for the fishery. But, the fishery has multiple impacts on the economy of Lake Erie and the quality of life."

Smith noted lawmakers in Congress have been coming together across the political divide to support the project. Congress will be funding 80% of the work at the Brandon Road Lock and Dam, while the state of Illinois is backing the project as well. He is grateful to see people taking the issue seriously and realizing how invasive species could pose a detriment to the numerous industries of the Great Lakes.

While the Brandon Road Lock and Dam project is a short-term project, it will have long-term effects on keeping invasive carp at bay. Prior to the Brandon Road project, Smith acknowledged some projects were contentious.

"A lot of the solutions and proposals to keep carp out of the Great Lakes were met with serious challenges," Smith recounted. "Not only just financial, but how much it would cost to, essentially, fill in and block the transfer of water so that you would stop carp from getting into Lake Michigan through the Chicago Sanitary and Wastewater Canal."

Given how many states border the Great Lakes, Smith knows invasive carp could pose a serious risk to the environments of the surrounding states as well as neighboring Canada. As technologies for keeping invasive species out of the Great Lakes have developed through time, Smith emphasized education must continue, so people understand why the Great Lakes are the wrong ecosystem for invasive carp.
