Final EPA Study Confirms Fracking Contaminates Drinking Water
The U.S. Environmental Protection Agency (EPA) has released its widely anticipated final report on hydraulic fracturing, or fracking, confirming that the controversial drilling process indeed impacts drinking water "under some circumstances." Notably, the report also removes the EPA's misleading line that fracking has not led to "widespread, systemic impacts on drinking water resources."
"The report, done at the request of Congress, provides scientific evidence that hydraulic fracturing activities can impact drinking water resources in the United States under some circumstances," the agency stated in a media advisory.
This conclusion is a major reversal from the EPA's June 2015 pro-fracking draft report. That specific "widespread, systemic" line baffled many experts, scientists and landowners who—despite the egregious headlines—saw clear evidence of fracking-related contamination in water samples. Conversely, the EPA's top line encouraged Big Oil and Gas to push for more drilling around the globe.
But as it turns out, a damning exposé from Marketplace and APM Reports revealed last month that top EPA officials made critical, last-minute alterations to the agency's draft report and corresponding press materials to soft-pedal clear evidence of fracking's ill effects on the environment and public health.
EPA Watered Down Major #Fracking Study to Downplay Water Contamination Risks https://t.co/9HhJdrSZ1R @GreenpeaceUK @globalactplan— EcoWatch (@EcoWatch)1480767012.0
Thomas Burke, EPA deputy assistant administrator and science advisor, discussed the agency's final report released Tuesday.
“There are instances when hyrdofracking has impacted drinking water resources. That's an important conclusion, an important consideration for moving forward," Burke told reporters today, according to The Hill.
Regarding the EPA's contentious "national, systemic conclusion," Burke said, "that's a different question that this study does not have adequate evidence to really make a conclusive, quantified statement."
In the new report, the authors heeded to the EPA's independent Science Advisory Board's advice to review the "widespread systemic impacts" line from the June 2015 draft study. The final 1,200-page report omits that line.

"Scientists put that language in the draft report, and scientists made the decision not to include it in the final report based on feedback from the Science Advisory Board and their interpretation of the available science," Burke explained.
The Science Advisory Board also took issue with how the draft report inexplicably omitted three critical fracking-contamination cases—Dimock, Pennsylvania; Parker County, Texas; and Pavillion, Wyoming.
As Pavillion rancher and affected landowner John Fenton testified last year, "When EPA launched its national study of fracking's drinking water impacts, we thought they'd look first here in Pavillion where they'd already found pollution. But instead they ignored us without explanation. Science means taking the facts as they are. But EPA seems to be intent on finding the facts to support the conclusion they've already reached—'fracking is safe.'"
These specific cases studies are now mentioned in the final report.
In the new report, the EPA has identified cases of impacts on drinking water at each stage in the hydraulic fracturing water cycle:
- Water withdrawals for hydraulic fracturing in times or areas of low water availability, particularly in areas with limited or declining groundwater resources;
- Spills during the management of hydraulic fracturing fluids and chemicals or produced water that result in large volumes or high concentrations of chemicals reaching groundwater resources;
- Injection of hydraulic fracturing fluids into wells with inadequate mechanical integrity, allowing gases or liquids to move to groundwater resources;
- Injection of hydraulic fracturing fluids directly into groundwater resources;
- Discharge of inadequately treated hydraulic fracturing wastewater to surface water resources; and
- Disposal or storage of hydraulic fracturing wastewater in unlined pits, resulting in contamination of groundwater resources.
Burke said that the EPA's assessment "provides the scientific foundation for local decision makers, industry, and communities that are looking to protect public health and drinking water resources and make more informed decisions about hydraulic fracturing activities."
"This assessment is the most complete compilation to date of national scientific data on the relationship of drinking water resources and hydraulic fracturing," he added.

Unsurprisingly, the oil and gas industry has criticized the report.
“It is beyond absurd for the administration to reverse course on its way out the door," American Petroleum Institute Upstream Director Erik Milito told The Hill. "The science and data clearly demonstrate that hydraulic fracturing does not lead to widespread, systemic impacts to drinking water resources. Unfortunately, consumers have witnessed five years and millions of dollars expended only to see conclusion based in science changed to a conclusion based in political ambiguity."
The industry-funded group Energy In Depth added that despite change in the central conclusion, the report still “blows apart the anti-fracking campaign's most common claim, namely that hydraulic fracturing is polluting groundwater all across America."
Meanwhile, public health and environmental groups and activists are saying the opposite.
"At last the EPA confirms what independent science has overwhelmingly determined for years, that drilling and fracking contaminate drinking water," said actor and prominent environmentalist Mark Ruffalo on behalf of the national Americans Against Fracking coalition.
"Across the country, Americans have had their lives turned upside down as fracking has poisoned the water coming out of their faucets and has made their families sick. Now all of our federal and state elected officials need to take action to protect Americans by banning fracking. Water is life," Ruffalo said.

Greenpeace researcher Jesse Coleman agreed. "The EPA's final report on impacts of fracking on groundwater has concluded what too many Americans already know from personal experience: Fracking has caused lasting harm to drinking water sources throughout the country," Coleman said. "The most important findings from this study is that drilling, fracking, and the use of hazardous chemicals necessary to frack have caused groundwater contamination. This puts to rest the widely repeated lie that fracking is 'safe' and has never caused drinking water contamination."
Julia Walsh from Frack Action said, "The EPA has rightly reported that fracking causes water contamination. For all of the Americans living with this tragedy every day, they are finally validated by the federal government."
Similarly, David Braun, Rootskeeper director, said "Kudos to President Obama's EPA for embracing the science about fracking, which clearly demonstrates serious and inherent problems with the practice."
"The EPA could have bowed to pressure from the oil and gas industry and didn't, however, now that the EPA has acknowledged the serious inherent problems with fracking, it is incumbent upon the Obama Administration to stand with the thousands of Americans who have had their water poisoned, and protect them from this dangerous practice," Braun continued.

"By listening to its scientists instead of its political advisors, EPA's fracking study sets an example that we hope, but do not expect, the Trump Administration to follow," Pagel said. "But a Scott Pruitt EPA would have to ignore 5 years of scientific study, and years of community impacts, to do otherwise. Unfortunately for the still suffering citizens of Pavillion, WY, Dimock, PA and Weatherford, TX, their EPA investigations didn't have advisory boards to publicly remind EPA that science trumps politics."
And Wenonah Hauter, the executive director of Food & Water Watch, said that "the EPA has confirmed what we've known all along: fracking can and does contaminate drinking water. We are pleased that the agency has acted on the recommendations of its Science Advisory Board and chosen be frank about the inherent harms and hazards of fracking."

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.
