Children’s Health: An Investment in Our Future

By Dr. James H. Johnson Jr.

Group of children at school

Children’s health is our best investment.

Although children make up 30 percent of the population, they are 100 percent of our future. As a former college professor, I’ve had the distinct honor of serving as an educator and mentor to many, many young people, and there is no greater personal or professional pleasure than watching that kind of investment grow.

Children's Health MonthToday marks the beginning of Children’s Health Action Week at EPA, and I’m thrilled to kick off a number of blog posts we will be sharing about what is without a doubt one of the greatest investments we make in our nation’s future: children’s environmental health research.

In 1998, EPA, together with our partner at the National Institute of Environmental Health Sciences (NIEHS), established the EPA/NIEHS Children’s Environmental Health and Disease Prevention Research Program (Children’s Centers), one of the most successful public health research programs in the world. The program funds multi-disciplinary, community- and university-based research centers that together serve as a network of top experts and practitioners in children’s environmental health.

The Children’s Centers program fosters collaborative research that connects scientists, social scientists, pediatricians, public health professionals and community organizations all focused on a single overarching goal: to improve the health and environments of children. Together, their work has led to groundbreaking research results. Examples include:

The Centers are explicitly designed to match researchers with public health experts and caregivers so that the results of their work quickly and effectively reach those who can put it into practice and protect children wherever they live, learn and play.

For the past 16 years, EPA has invested over $130 million (matched by NIEHS) to fund more than 30 Children’s Centers.

This week, EPA is not only celebrating the great strides we have made in children’s health research, but we are also recommitting ourselves to our overall mission of ensuring safe and healthy lives for all children. The Children’s Centers are providing the research that will help parents and mentors achieve that. It is a rewarding investment.

Please join me in celebrating children’s health week and 16 years of scientific achievement by learning about how EPA and its partners are providing a better world for our children, today.

About the Author: Dr. James H, Johnson Jr. is the Director of EPA’s National Center for Environmental Research, which runs the Agency’s Science to Achieve Results (STAR) program as well as other grant, fellowship, and awards programs that support high quality research by many of our nation’s leading scientists and engineers.

Local Water Woes, No More? Advancing Safe Drinking Water Technology

By Ryann A. Williams

P3 Team shows their water filter

The SimpleWater company got their start as an EPA P3 team.

As a child growing up in Washington, D.C. I remember hearing adults talk about their concerns about the local tap water. Overheard conversations about lead content and murkiness in the water certainly got my attention. As an adult who now works at the Environmental Protection Agency, I know things have greatly improved.

Today, DC tap water is among the least of my concerns. I drink it every day. Frequent testing to confirm its safety and public awareness campaigns by DC Water (the District of Columbia Water and Sewer Authority) have put my own worries to rest. But in other parts of the world and even in some areas of the U.S., people still have a reason to worry about their drinking water: arsenic.

Globally, millions of people are exposed to arsenic via drinking water and can suffer serious adverse health effects from prolonged exposure.

This is especially true in Bangladesh where it is considered a public health emergency. Other countries where drinking water can contain unsafe levels of arsenic include Argentina, Chile, Mexico, China, Hungary, Cambodia, Vietnam, and West Bengal (India). In addition, parts of the U.S. served by private wells or small drinking water systems also face risks due to arsenic in their drinking water.

Remedies are expensive and both energy- and chemical-intensive.

In 2007, a student team from the University of California, Berkeley won an EPA People, Prosperity and the Planet (P3) award for their research project aiming to help change that.

Explaining the arsenic removal project.

Explaining the arsenic removal project.

The students set out to test a cost-effective, self-cleaning, and sustainable arsenic-removal technology that employs a simple electric current. The current charges iron particles that attract and hold on to arsenic, and are then removed by filter or settle out of the water.

By the end of their P3 funding in 2010, promising results had allowed the team to extend their field testing to Cambodia and India, and move forward with the licensing and marketing of their product to interested companies in Bangladesh and India.

Today, the same group of former Berkeley students who formed the P3 team now own a company called SimpleWater.

SimpleWater is among 21 companies that recently received a Phase One contract from EPA’s Small Business Innovation Research Program.

SimpleWater aims to commercialize their product and bring their track record of success in Bangladesh and India to help Americans who may be at risk from arsenic exposure in their drinking water. In particular they’re focusing on those who live in arsenic-prone areas and whose drinking water is served by private wells or small community water systems that test positive for elevated arsenic levels. (Learn more about Arsenic in Drinking Water and what to do if you think testing is needed for your water.)

Thanks to EPA support, SimpleWater is working to reduce the threat of arsenic in small drinking water systems and private wells. With their help, millions of people may soon feel safer about their drinking water, and like me, have one less big thing to worry about.

A Job Worth Doing is Worth Doing Together

By Janice Lee 

Arsenic element from periodic tableMost everyone recognizes the value of teamwork. We learned this from a young age in school, and most people can point to a professional experience where a project has improved because of group input. For me, a terrific example is the inorganic arsenic health assessment that EPA is currently developing through our Integrated Risk Information System (IRIS)—a program that provides information on the health effects that may result from exposure to environmental contaminants.

Arsenic is well known—it’s been used since ancient times for a variety of purposes, it had a major role in the Hollywood movie Arsenic and Old Lace, and many people are familiar with health issues that occur in areas where naturally-occurring arsenic shows up in high levels in drinking water.

Throughout 2013, our team met with a lot of people who will use our inorganic arsenic assessment once it’s developed. We learned a lot from those conversations, including several things that will ultimately improve our assessment and make it more useful to the people who make decisions to protect public health. For example, we had initially planned to focus our assessment on oral exposures—the kind you might get from drinking water or eating food contaminated with inorganic arsenic. Based on the feedback we heard from others, we realized it was important to include information about the potential health effects of inhaling inorganic arsenic, too.  We were also reminded that providing information about those populations that may be more sensitive to the effects of inorganic arsenic is important to the users of the inorganic arsenic assessment.

We also learned that many people wanted to continue to have discussions on science issues that may inform the development of the assessment.  We agreed this was important, and in response started an arsenic webinar series.

To date we have held eight webinars on various topics relevant to assessing the human health risks of exposure to inorganic arsenic. For example, we held one webinar on inorganic arsenic and its potential effects on children’s neurodevelopment. We heard that the most sensitive endpoints to look at when examining the relationship between arsenic and children’s neurodevelopment are IQ and behavior.  We held another one on environmental justice issues related to inorganic arsenic. During that one, we heard about the importance of considering social stressors when looking at susceptibility.  This includes access to nutritional food, health care and prenatal care, and housing conditions.

I have really enjoyed holding these webinars. The talks have been informative, and it has been a great forum for discussion and input. I am happy to note that we are committed to engaging partners and public stakeholders throughout the development of the inorganic arsenic assessment. The next opportunity to provide feedback will be the upcoming IRIS June Bimonthly Public Meeting.

We have released several products for public input and discussion, including an assessment development plan, literature search, risk of bias evaluations for the studies under consideration, evidence tables, and some qualitative summary information about mode of action hypotheses (the chain of events that happens in the body after exposure to cause a health effect).

In addition, we will also be discussing key science issues relevant to assessing the health hazards of inorganic arsenic. A list of these issues is available on our website. We encourage you to help us identify additional science issues that you think are important.

These public discussions will ultimately help shape the science of our assessment. We hope you can join us for the conversation—your input could prove to be another terrific example of the power of teamwork!

Improving Water by Removing Arsenic

By Marguerite Huber

Arsenic removal system, Twentynine Palms, CA.

If you lead an active and busy life like me, you probably don’t spend a lot of time thinking about what is in the water you drink. You just fill up your water bottle and are out the door.

But behind the scene a lot goes into making our water safe to drink. To protect public health, EPA regulates arsenic in drinking water. Arsenic is a semi-metal element that can enter drinking water supplies through natural deposits or from agricultural and industrial practices. Health effects due to prolonged excess exposure can include skin damage, circulatory system problems, and increased risk of cancer.

EPA initiated the Arsenic Removal Technology Demonstration Program to evaluate the performance, reliability, and cost of arsenic removal and the effect on water distribution systems. One type of arsenic removal system consists of a tank of adsorptive media that is similar to a home water softener.

As the water passes through the tank of media, the dissolved arsenic adsorbs on to surface of the media. Adsorption is not to be confused with absorption, which is the process in which a fluid is dissolved by a liquid or solid, such as water being absorbed by a sponge.

Adsorption on the other hand is the process in which atoms, ions or molecules, stick to a surface. Once the media reaches its arsenic removal capacity, the media must be replaced. Many water systems, such as the Twentynine Palms Water District in California, have experienced high operating costs due to frequent replacement of the adsorptive media.

EPA researchers partnered with Battelle to conduct lab and pilot studies to investigate the possibility of these media being reused to reduce costs. The study found that as much as 94% of the arsenic from exhausted media could be removed and the media could be regenerated.

Following the successful results of the laboratory regeneration study, EPA and Battelle demonstrated the efficiency of media regeneration in Twentynine Palms, CA. The testing led to substantial reductions in the operational cost, proving to be successful and that regeneration can work.

The goal of this research was to reduce operating costs, and since starting the regeneration program in 2010, Twentynine Palms Water district has been saving about $20,000 a year.

All in all, there is a lot of science and technology that bring you the clean water in your water bottle.  I’m now going to stop and appreciate that each time I fill up my water bottle.

My Confidence in Future Young Scientists

By Thabit Pulak

EPA guest blogger Thabit and friends

The students were taking part in “enrichment clusters,” sessions in which they learn about one important public issue in depth. I was invited by 2nd-grade teacher Ms. Claborn to visit her cluster on water purification and to present a real-life example of a water filter.

I had recently worked to develop an affordable filter that removed not only bacteria and contaminants from water, but also arsenic, a poisonous substance that affects nearly 150 million people across the world today. I had the opportunity to present my water filter at the 2012 Intel International Science Fair, where I won 3rd place and EPA’s Patrick J. Hurd Sustainability Award. The Hurd Award included an invitation to present my project at the annual National Sustainable Design Expo, which showcases EPA’s People, Prosperity, and the Planet (P3) program.

STEM in the classroomI presented the filter to the class and answered questions, learning just as much from them as they did from me.  I was invited to stay for the remainder of the cluster, where the students were putting final touches on their own water filters. Ms. Claborn gave each of the students some muddy water to run through the filters. It was exciting for me to see the children’s smiles as they looked at the clean water slowly trickling out of the open edge of the soda bottle after traveling through the sand and rocks. The filters were based on a water filtration activity that EPA designed specifically for students.

Afterwards, I was invited to attend the upcoming STEM (Science, Technology, Engineering, and Math) exhibit that the school was hosting. The students’ mini filters would be on display, and I was invited to display my filter alongside theirs. As the stream of curious parents and students came in, I gladly talked about both what the students did and my own filter, and what this means for the future of environmental sustainability issues like water.

This was my first opportunity to present my work outside of my school and science fairs. I felt very honored and happy to be able to give something back to the community. I hope to find ways to keep doing so!

Injecting Knowledge to Cure Injustice

By Dr. Sacoby Wilson

Growing up in Vicksburg, Mississippi, I had a fondness of the Big River and the love of the environment.  Unfortunately, I was aware that some communities did not enjoy the same level of environmental quality that others did.  I grew up near a concrete plant, waste water treatment plant, oil facility, and power plant in the background.  My father was a pipefitter who over the years worked at nuclear power plants, oil refineries, coal fired plants and was exposed to many contaminants.  These experiences, combined with my diagnosis at age 7 with alopecia areata, an autoimmune disease, really drove me to explore why some communities were burdened by hazards and unhealthy land uses and how exposure to environmental stressors can lead to negative health outcomes.


I was inspired to use my interest in science and environmental health for environmental justice after meeting Drs. Benjamin Chavis and Robert Bullard in the early 1990s. These professors taught me the value of getting out of the ivory towers of academia and getting into communities to spread knowledge to push for positive change. Since then, I have been a passionate advocate for environmental justice working in partnership with community groups across the United States. Through this work, I have learned that the use of science to empower through education, paired with community organizing and civic engagement, is the key to alleviating environmental injustices.

One of those individuals who helped me understand the importance of getting communities into the research process was Omega Wilson.  Wilson’s Group, the West End Revitalization Association (WERA) has  fought against environmental injustice, infrastructure disparities, and the lack of basic amenities for the last twenty years.  WERA leaders have used a community-driven research approach known as community-owned and managed research (COMR) to address environmental injustice in their community.  COMR focuses on the collection of data for action, compliance, and social change.  In combination with EPA’s collaborative-problem-solving model, WERA’s work provides a blueprint for other communities to use partnerships, stakeholder engagement, action-oriented research, and legal tools to achieve environmental justice.

Untitled-2As a professor who learned through my mentors, I also firmly believe in inspiring the next generation of academics to take their tools and research into communities that need it the most. Currently, I am building a program on Community Engagement, Environmental Justice, and Health (CEEJH) at the University of Maryland-College Park. CEEJH is building off existing work of leaders in the DC Metropolitan region to address environmental justice and health issues at the grassroots level; we use community-university partnerships, capacity-building, and community empowerment to address environmental justice and health issues in the Chesapeake Bay region.  Following in the footsteps of WERA, I plan to inspire young people to be bold, courageous, and become advocates for environmental justice.

About the author: Dr. Wilson is an environmental health scientist with expertise in environmental justice and environmental health disparities. His primary research interests are related to issues that impact underserved, socially and economically disadvantaged, marginalized, environmental justice, and health disparity populations. He is building a Program on Community Engagement, Environmental Justice, and Health (CEEJH) to study and address health issues for environmental justice and health disparity populations through community-university partnerships and the use of CBPR in Maryland and beyond.

Arsenic Arresters

By: Hudson, Brett and George

“Water is the one substance from which the earth can conceal nothing; it sucks out its innermost secrets and brings them to our very lips” (Jean Giraudoux, 1946). Water is essential for all dimensions of life. The quality of water in rivers and underground has deteriorated, due to pollution by waste and contaminants from cities, industry and agriculture.  Over one billion people lack safe water. Since water is so essential to our health, then we should strive to make our drinking water as safe as we can from contaminants.

We are a sixth grade team of three students from Whiteface, Texas. We read an article in the Lubbock Avalanche-Journal concerning the high levels of arsenic in a family’s drinking water, which comes from their private well. It led to serious health problems for the entire family. Our team began researching the topic and learned that arsenic is a semi-metallic element and originates in many geological formations.  It is found in soil, river sediments, and the water supply in some regions. The groundwater of the Ogallala Aquifer supplies all our water at the tap, and for irrigating cotton, peanuts, and wheat crops of Texas. Arsenic-contaminated groundwater constitutes a health problem.  The EPA acceptable level of arsenic in drinking water is 10 parts per billion (ppb).  Inorganic arsenic is a human carcinogen that is linked to liver, lung, kidney, bladder and skin cancers as well as Type 2 diabetes. Arsenic, according to the Dartmouth Toxic Metals Superfund Research Program, is considered the number one environmental chemical of concern for human health in the U. S. and worldwide.

In the agricultural region where we live, the drinking water has arsenic values from 11-30 parts per billion. Our team is researching and testing different methods to reduce the amount of arsenic in our drinking water and our soil. We are working with environmental scientists from Texas Tech University and West Texas A & M University to find solutions.

Is there anyone else concerned about this problem? Is any research being done in your area?  Are you an expert in this field who would share information with us? We are called the Arsenic Arresters and we are interested in educating others and decreasing the risk of arsenic contamination.

Hudson, Brett, and George enjoy working outside, being with family, playing basketball, and playing Minecraft when they’re not saving the world from arsenic contamination!

Cutting Mercury and Protecting America's Children

by Administrator Lisa P. Jackson

From historic efforts to cut pollution from American automobiles to strong measures to prevent power plant pollution from crossing state lines, 2011 was already a banner year for clean air and the health of the American people. And the EPA is closing out the year with our biggest clean air protection yet.

Last week, we finalized the Mercury and Air Toxics Standards, or MATS, a rule that will protect millions of families and, especially, children from air pollution. Before this rule, there were no national standards that limited the amount of mercury, arsenic, chromium, nickel and acid gases power plants across the country could release into the air we breathe. Mercury is a neurotoxin that is particularly harmful to children, and emissions of mercury and other air toxics have been linked to damage to developing nervous systems, respiratory illnesses and other diseases. MATS will require power plants to install emissions controls that will also reduce particle pollution, which has been linked to premature death and cardiovascular and respiratory diseases.

As a result, MATS will provide between $37 billion and $90 billion in health benefits for the American people. Once the rule is fully implemented in 2016, it will prevent up to 11,000 premature deaths, 4,700 heart attacks, and 130,000 cases of aggravated asthma among children between six and 18 years old.

That last point is especially significant to me as a mother. I understand the importance of MATS in very profound ways, because both of my sons have struggled with asthma. Fifteen years ago, my youngest son spent his first Christmas in the hospital fighting to breathe. Like any parent of a child with asthma, I can tell you that the benefits of clean air protections like MATS are not just statistics and abstract concepts.

What we’re really talking about with all those numbers above are pregnant mothers who can rest a little easier knowing their children won’t be exposed to harmful levels of mercury in critical development stages. We are talking about reducing the levels of mercury in the fish that we and our kids eat every day. We are talking about future generations growing up healthier because there is less toxic pollution in the air they breathe.

Find out how MATS will protect health in your state.

What we’re also talking about with MATS are thousands of new opportunities for American workers. Not only will MATS provide health benefits that far outweigh the costs of compliance, it will also support jobs and innovation for our economy.

To meet the MATS standards over the next several years, many power plants will have to upgrade their operations with modern and widely available pollution control technology. There are about 1,100 coal-fired units that are covered by MATS, and about 40 percent do not use advanced pollution controls to limit emissions. Increased demand for scrubbers and other advanced pollution controls will mean increased business for American companies that lead the way in producing pollution control technology.

But that’s just the start. Power plants making upgrades will need workers to build, install, operate and maintain the pollution controls. As the CEO of one of the largest coal-burning utilities in the country recently said about cutting emissions by installing pollution control technology, “Jobs are created in the process – no question about that.” The EPA estimates that the demands for workers will support 46,000 short-term construction jobs and 8,000 long-term jobs.

The Mercury and Air Toxics Standards will protect millions of families and children from harmful and costly air pollution, provide the American people with health benefits that far outweigh the costs of compliance, and support job creation and innovation that are good for our economy. Families across the country – including my own – will benefit from the simple fact of being able to breathe cleaner air. That is what environmental protection and the work of the EPA is all about.

In this holiday season as we gather with our friends and families, Americans can take pride in the gift of clean air. Our children and future generations will have healthier air to breathe because of MATS and this historic year for clean air protection.

Telling the Truth About the Environment and Our Economy

This is cross-posted from The Huffington Post

By Administrator Lisa P. Jackson

It’s a certainty in Washington that lobbyist talking points and inside-the-beltway speeches are going to be overblown and exaggerated. But lately, misleading claims about the EPA’s work have been making their way into the mainstream debate.

The most notable is an industry report that the EPA is responsible for an unprecedented “train wreck” of clean air standards that will lead to the mass closure of power plants. The “train wreck” claim has been repeated by everyone from congressional leaders to major newspapers. It sounds pretty scary, but the trouble with these reports — there is no “train wreck.”

Earlier this month a Congressional Research Service report concluded that industry’s claims were made “before EPA proposed most of the rules whose impacts they analyze,” and are based on “more stringent requirements than EPA proposed in many cases.”

On the issue of plant closures, I take the word of industry leaders like the Chairman and CEO of Exelon Corporation, who said “These regulations will not kill coal… up to 50% of retirements are due to the current economics of the plant due to natural gas and coal prices.” The Congressional Research Service report also found that EPA’s standards will primarily affect “coal-fired plants more than 40 years old that have not, until now, installed state-of-the-art pollution controls.” That echoed the remarks of the CEO of American Electric Power from April of this year: “We’ve been quite clear that we fully intend to retire the 5,480 megawatts of our overall coal fleet because they are less efficient and have not been retrofitted in any particular way.”

This is just one example from the larger debate over the EPA’s effect on the economy. That’s an important debate when job creation is our nation’s top priority, and that makes it all the more troubling to see the EPA attacked for measures we haven’t actually proposed, and to hear our fundamental responsibility of protecting the health and environment for all Americans targeted as an enemy of job creation.

Some in Washington are working to weaken safeguards and undermine laws that protect our families from pollution that causes asthma, cancer and other illnesses, especially in children. Big polluters are lobbying congress for loopholes to use our air and water as dumping grounds. The result won’t be more jobs; it will be more mercury in our air and water and more health threats to our kids. As a senior official from the Bush EPA recently wrote, “Abolishing the EPA will not cause a revival of America’s economy, but it will certainly result in a major decline in public health and our quality of life.”

It’s time for a real conversation about protecting our health and the environment while growing our economy. EPA’s 40 years of environmental and health protection demonstrate our nation’s ability to create jobs while we clean our air, water and land.

When big polluters distort EPA’s proposals as a drag on our economy, they ignore the fact that clean air, clear water and healthy workers are all essential to American businesses.

They also overlook the innovations in clean technology that are creating new jobs right now. The CEO of Michigan’s Clean Light Green Light recently said, “EPA has opened the doors to innovation and new economic opportunities. By spurring entrepreneurs who have good ideas and the drive to work hard, the EPA has helped give rise to countless small businesses in clean energy, advanced lighting, pollution control and more, which in turn are creating jobs.”

It’s time to recognize that delays of long-expected health standards leave companies uncertain about investing in clean infrastructure, environmental retrofits, and the new workers needed to do those jobs. These are potential opportunities for engineers and scientists, as well as pipefitters, welders and steelworkers. Pledges to weaken or slow proposed standards, many of which have been developed over years and with industry input, prevent businesses from investing in those jobs.

Some leaders in congress have already stated their intent to roll back critical environmental protections when they return to session. Misleading claims are translating into actions that could dismantle clean air standards that protect our families from mercury, arsenic, smog and carbon dioxide. All of this is happening despite the evidence of history, despite the evidence of Congress’ own objective Research Service, and despite the need for job creation strategies that go well beyond simply undermining protections for our health, our families and our communities.

Telling the truth about our economy and our environment is about respecting the priorities of the American people. More than 70 percent of Americans want EPA to continue to do its job effectively. Those same Americans want to see a robust economic recovery. We have the capacity to do both things if we don’t let distractions keep us from the real work of creating jobs.

Science Wednesday: Searching for a Sustainable Way to Remove Arsenic from Groundwater

Each week we write about the science behind environmental protection. Previous Science Wednesdays.

Many people in Bangladesh use groundwater for their drinking water. In some parts of Bangladesh, arsenic levels in groundwater are more than 100 times the World Health Organization’s recommended limit of 10 parts per billion. Already, 40,000 Bangladeshis are showing signs of arsenic poisoning. Without intervention, 10% of the deaths in this country of 140 million people could be caused by arsenic poisoning.

I am part of the Berkeley Arsenic Alleviation Group (BAAG), a group aiming to provide affordable, sustainable technologies to remove arsenic from groundwater. Our goal is an efficient and cheap technology that removes arsenic and can be easily operated and maintained by local communities.

Our technology, partly funded by an EPA People, Prosperity and the Planet (P3) Award research grant, takes advantage of the fact that arsenic binds to rust. We first put iron into water and then use electricity to corrode the iron and produce rust. Then by filtering the water, or allowing the rust to settle, we can remove the arsenic.

From an engineering standpoint, the design efficiently and sustainably removes arsenic from water . But we can’t just drop it off and leave.

First, we need to figure out if the technology will be affordable for local communities. Are there cultural barriers that might prevent its use? Can this new technology be easily adopted and used?

To develop a sustainable solution to real-world problems, we need an interdisciplinary approach with collaboration among engineers, social scientists, and most importantly local communities.

Because local communities are so important, we are proposing a community-scale clean water center. It will be operated by the local community, for the local community—selling clean water at an affordable price (~$0.02 per person per day). It means partnerships with local people, the key to the sustainability of our technology.

We are now collaborating with local universities, local village leaders, local communities, and local entrepreneurs. By operating a treatment center themselves, the community will be empowered, leading to more likely acceptance and sustainable operations.
