EPA Releases Final Report of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources

By Tom Burke

Clean and safe drinking water is central to public health—something that we work hard every day at EPA to protect.

Today, we’ve taken an important step forward in this mission. With the release of our final assessment of the impacts of hydraulic fracturing on drinking water resources, EPA is providing a strong scientific foundation for states and local decision makers to better protect drinking water resources in areas where hydraulic fracturing occurs or is being considered.

When EPA started this study, we were asked by Congress to scientifically assess the relationship between hydraulic fracturing and drinking water.

As part of conducting these studies, we met with stakeholders, collecting input that helped to make our work stronger. We reviewed thousands of sources of data and information. And we advanced the scientific understanding of hydraulic fracturing activities and their impacts on drinking water resources in the United States.

We passed this information on to others by publishing 13 EPA technical reports and just as many articles in scientific journals.

The report does two important things—it outlines what the scientific evidence shows and underscores what we don’t know because of gaps in the data. While these data gaps limited EPA’s ability to fully assess the potential impacts to drinking water resources locally and nationally, they too can serve as an important guide to local communities considering hydraulic fracturing.

Most importantly it provides states, tribes, and communities around the country a critical resource they can use to identify how to better protect public health and our drinking water resources.

In the end, I believe the assessment truly reflects the current state of the science. It cites over 1,200 sources including published papers, technical reports, results from peer-reviewed Agency research, and information provided by industry, states, tribes, non-governmental organizations, and other interested members of the public.

States and industry can now add the scientific understanding gained through this assessment to many other resources—including engineering capability and technology—to ensure that hydraulic fracturing is conducted in a safe and responsible manner.

But there is a last point that should not be glossed over, and that is the strength of the scientific process. I can tell you from experience, good science takes time. It involves careful planning, requires rigorous attention to detail, and relies on feedback through scientific peer review. In this instance, the Agency’s independent Science Advisory Board provided rigorous peer review and numerous constructive comments.

The final assessment is a strong, clear representation of the science that exists on the relationship between hydraulic fracturing and drinking water resources.

The Sweet Spot: Riding to Work

LekKadeli Lek Kadeli

By Lek Kadeli

There are times in life when everything seems to align. When you know you are in the right place at the right time, doing something that is at once productive and satisfying. I’ve found a regular activity that fits the bill: bicycle commuting.

I began making the switch to two-wheeled commuting over time. At first I was primarily looking for a way to build a bit more physical activity into my weekly routine. I began leaving the car at home from time to time in favor of riding. It turned out to be an easy transition. Continue reading

EPA’s Report on the Environment: Tracking National Trends Over Time

LekKadeli Lek Kadeli

With the cold winter still stubbornly hanging on, it’s a bit hard to believe that next week marks the beginning of the 2014 baseball season. As a life-long fan of the game, I always find it easy to slip back into the routine of reading the daily box scores each evening, keeping an eye on batting averages and other pertinent statistics, and assessing the progress of my favorite team—the New York Yankees! I am usually ready to start thinking about October travel plans to the watch playoff home games in the Bronx sometime around the All Star break.

The ability to monitor the state of my team is one of the truly gratifying aspects of baseball. Having a similar ability to assess and monitor trends when it comes to the environment is even a more gratifying aspect of meeting our mission here at EPA: to protect human health and the environment.

Healthy Hearts and Clean Air: An EPA Science Story

LekKadeli Lek Kadeli

healthy-heart-banner

This month is American Heart Health Month. I invite you to join me in understanding how EPA scientists and their partners are learning how to better protect a group of citizens who are among the most at risk from poor air quality: those who suffer from heart and other cardiovascular diseases.

Our researchers have made important discoveries linking the impact of poor air quality on cardiovascular health. For example, EPA scientists Robert Devlin, Ph.D., and David Diaz-Sanchez and their colleagues published one of the first studies looking at the effects of ozone exposure on heart health. They discovered a link between breathing ozone and inflammation, and changes in heart rate variability, and proteins that dissolve blood clots that could be risk factors for people with heart disease.

Drs. Devlin and Diaz-Sanchez, along with EPA cardiologist Dr. Wayne Cascio, are part of an Agency effort to spread the word about the results of EPA clean air research. We will be highlighting those efforts on the Agency’s science blog, It All Starts with Science, on our science Twitter feed @EPAresearch, and elsewhere as part of our Healthy Heart Month activities.

Clearing the Air: EPA Secondhand Smoke Research Making a Difference

Bob Perciasepe Bob Perciasepe

Today, no-smoking policies have become so widespread that we hardly think twice when we’re enjoying a meal at a restaurant in a smoke-free environment.

Millions of Americans benefit from these policies, which have significantly reduced exposure to secondhand tobacco smoke in public spaces. A few recent studies show us that further reducing exposure can save the U.S. $10 billion annually in healthcare costs and wages lost to sick leave.

Secondhand smoke, passive smoking, side stream smoke, or environmental tobacco smoke (ETS) all refer to the same thing: the smoke exhaled by a smoker or given off by the burning end of a cigarette, pipe, or cigar.  Whatever you call it, thanks to EPA scientists we know that exposure to such smoke threatens our health—and is especially risky for those most vulnerable like older Americans and our kids.

Through their research, our scientists released a landmark health assessment in 1992, The Respiratory Health Effects of Passive Smoking: Lung Cancer and Other Disorders, that found that secondhand smoke leads to serious health complications, and even premature death. The assessment concluded that infants and young children were especially sensitive to secondhand smoke exposure, leading to more respiratory infections like bronchitis and pneumonia, harming lower lung function, and worsening symptoms of asthma.

In his State of the Union address, President Obama said “the nation that goes all-in on innovation today will own the global economy tomorrow.” He made the point that science and research are critical to keeping that competitive edge—but also to protecting our public health and our environment. I couldn’t agree more.

Science has always been at the heart of our mission at EPA. In the State of the Union address, President Obama doubled down on his commitment to using science to address a changing climate and carry out his Climate Action Plan—which aims to curb carbon pollution, build climate resilience in our towns and cities, and lead the world to a sustainable, clean energy future.

Yesterday, I was up in Philadelphia joined by CEQ Chair Nancy Sutley and Mayor Nutter to announce nearly $5 million in EPA grants made possible through the Science to Achieve Results (STAR) program. These investments are going to five universities, and aim to fill gaps in research evaluating the costs and benefits of certain green infrastructure practices.

The projects to be invested in, led by Temple University, Villanova University, Swarthmore College, University of Pennsylvania and University of New Hampshire, will explore the financial and social costs and benefits associated with green infrastructure as a stormwater and wet weather pollution management tool.

From rain gardens and permeable pavement to using absorbent landscape materials to soak up rainwater and more, the knowledge we gain will pay dividends not just for Philadelphia, but for cities all across the country. Green infrastructure can save money, promote safe drinking water, and build more resilient water systems—especially in the face of climate change.

Results from these university research teams will supplement a growing body of knowledge that EPA’s own researchers are uncovering. From monitoring and performance evaluation to creating models and a toolbox of green infrastructure resources for decision-makers, this research will be valuable to the city of Philadelphia and beyond.

We’re especially proud of the great work going on through Philly’s Green City, Clean Waters program. Our ongoing partnership between our researchers, EPA regional staff, academia, and the City of Philadelphia under Mayor Michael Nutter is a model for others to follow. We’re helping make real progress at the community level. Community progress isn’t just what guides our actions—it’s a measure of our success in fulfilling EPA’s mission of protecting public health and the environment.

And we’ll continue to rely on that kind of collaboration—especially when it comes to climate change. Luckily, Philadelphia has made major progress, thanks to Mayor Nutter’s efforts in cutting carbon pollution and preparing the city for climate impacts. As a member of President Obama’s State, Local and Tribal Leaders Task Force on Climate Preparedness and Resilience, Mayor Nutter’s advice will be critical to make sure  our climate preparedness and resilience policies respond to the needs of communities. The advice we get from the Task Force is an important component to our national Climate Action Plan to combat climate change broadly.

We have come a long way in the 40 years since the Clean Water Act. But with new challenges like climate change—we need push forward with community-focused, innovative solutions. That’s why locally focused partnerships like Green City, Clean Water, and ground level solutions like green infrastructure, are paving a pathway for progress.

I’m confident that through our STAR program, investments in these projects will go a long way to developing innovation solutions to stormwater management, wet weather pollution, and building more resilient, safer water systems for all.

It All Starts with Science: Answering Questions about Mining in Bristol Bay, Alaska

LekKadeli Lek Kadeli

Considering the scope of resources in Bristol Bay – a 37.5 million average annual run of sockeye salmon; $480 million in ecosystem-generated economic activity in 2009; 14,000 full- and part-time jobs from that activity; and 11 billion tons in potential copper and gold deposit – it is no wonder there was significant interest in an EPA science assessment to understand how wild salmon and water resources in the Bristol Bay watershed might be impacted by large-scale mining operations. The public comment periods generated 230,000 responses on the first draft of the assessment, and 890,000 on the second.

This week, after reviewing all those comments and formal peer review by 12 scientists with expertise in mine engineering, fisheries biology, aquatic biology, aquatic toxicology, hydrology, wildlife ecology, and Alaska Native cultures, EPA released its final report, “An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska.”

More than three years ago, several Bristol Bay Alaska Native tribes requested EPA take action under the Clean Water Act to protect the Bay and its fisheries from proposed large-scale mining. Other tribes and stakeholders who support development in the Bristol Bay Watershed requested EPA take no action until a permitting process begins.
