This year, once again, I resolved not to watch so much football and not to put on extra pounds doing so. I also resolved to take an active part in EPA’s Year of Science 2009. Now that I have broken my first resolution, I am even more resolved to keep my second resolution, and I need your help.
 
EPA is partnering with the Coalition for the Public Understanding of Science to support the Year of Science 2009 (YOS). This is a national, year-long celebration of science that will shine the spotlight on how science works, who scientists are, and why science matters. Activities and events will be led by a wide variety of scientific organizations, and I’m proud to say that EPA is one of them.

Each month will be organized around a specific theme, starting in January with the “Process and Nature of Science.” Given EPA’s world-class science and technology in support of our mission to protect human health and the environment, we’re looking forward to sharing real-world stories of EPA “Science in Action.”

Also, be sure to mark your calendars for EPA-sponsored activities during May. We’re taking the lead in organizing events and awards in support of the YOS theme of “Sustainability and the Environment,” because sustainability is an important topic across EPA. I plan to keep my New Year’s resolution by actively participating in May, and throughout the year. Please join me!

For more details about YOS, keep an eye on EPA’s Science Wednesdays, where you’ll find actionable information each month. Also, take a look at the site developed by the Coalition for the Public Understanding of Science, YearOfScience2009.org, to learn more about how you can get involved.

I can already tell it’s going to be a Happy New Year—of Science.

Be sure to check out our Year of Science Question of the Month, What kind of a scientist would you like to be?

For each month in 2009, the Year Of Science, we will pose a question related to science. Please let us know your thoughts as comments. Feel free to respond to earlier comments or post new ideas.

Ponder. Observe and discover. We are all born scientists, naturally curious to figure out more about the world around us: how we affect the environment, and how the environment affects us.
2009 is the Year Of Science.

If you could be any type of scientist, what kind would you be and why?

January is National Radon Action Month, and I hope that it can be the time when you take a small step to protect your family by testing your home for radon. Until I started working at EPA, radon testing wasn’t on my radar, much less my to-do list. I have vague memories of hearing about it in high school chemistry class, but I never thought of it as something I should be concerned about. In my job as a communication specialist, I sift through a lot of meaningful statistics. This one really stands out - radon is the second leading cause of lung cancer. Knowing I could prevent something as serious as cancer with something as simple as a radon test astonished me.

Every day I have to explain a wide range of issues so that the public can easily understand them. In this case, my parents were my target audience - they hadn’t tested their home for radon. I bought them a radon test kit and dropped it off at their house. Little did I know that I was about to face my greatest communication challenge yet: my mom. When I arrived with the test kit, she eyed the package warily and asked dozens of questions. She was worried about what would happen if we found high radon levels, whether the test was accurate, and if it was even necessary. It took some convincing, but in the end she agreed that their health was paramount, and we sent off the test. When we get the results back, we will have the peace of mind of knowing that either our radon levels are low, or that they soon will be after we install a radon mitigation system.

Movies require you to suspend your disbelief, but when you watch a film that hits close to home it can be tough. I have a friend in federal law enforcement who squirms when cardboard cutout agents run across the screen. Action flicks don’t do his profession justice, but at least his job is sometimes glorified on celluloid. The only two movies I can remember featuring a prominent EPA employee are Ghostbusters and the Simpsons Movie, neither of which ever made a kid say, “Man, when I grow up I want to work for the EPA.” On the off-chance your youngster was inspired to seek out public service please let them know we don’t inspect unlicensed nuclear storage facilities, nor do we have a fleet of helicopters. We do however, have one cool plane.

EPA’s Airborne Spectral Photometric Collection Technology, known as ASPECT, is an aircraft equipped with sensors that allow for surveillance of gaseous chemical releases from a safe distance. ASPECT gives emergency responders information regarding the shape, composition and concentration of gas plumes from disasters such as a derailed train, factory explosion or terrorist attack.

Since its inception ASPECT has flown over several fires, provided support during the Olympics and Columbia shuttle recovery, and supplied some of the first aerial images of the devastation along the coast during Katrina.

This was the scene in Kansas City outside our office windows in 2007 when a chemical facility went up in flames. ASPECT deployed and was instrumental in verifying that while ominous, the fire did not present a significant health threat to the community (the white signature you see below is the fire).>

Most of the technology you see in movies is sheer fantasy, but EPA’s high-tech plane and the scientists who operate it are worthy of a spot in the next summer blockbuster. Here’s hoping for the appearance of an EPA scientist who isn’t a bad guy (although with my face the best I could hope for is Thug #4 in the next straight to DVD clunker).

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

Many of America’s streams, rivers, and lakes are not clean enough for swimming or fishing. In the past, much of the nation’s water quality problems were caused by industrial and municipal dumping. Thanks to the Clean Water Act, however, many of these sources of pollution have been greatly reduced.

So why are America’s urban rivers still not swimmable and fishable?

The answer is that every time it rains, the streets and rooftops of developed areas are washed clean by the downpour. All that water has to go somewhere. Stormwater runoff carrying loads of various contaminants has been the top water quality problem in the U.S. since 1994.

One strategy for dealing with polluted stormwater runoff has been to keep it from flowing too far—using devices such as rain barrels, retention ponds, green roofs to catch, slow down, and treat it. While these engineering devices help a great deal, they apply to small, distinct points across watersheds that are spread out over large regions.

That’s where my work comes in.

I am building a computer simulation of urban development and hydrology in Mecklenburg County, North Carolina (the home of the city of Charlotte) in order to explore how different regional urban forms of development could impact future water quality.

Rapid urban growth and its environmental consequences are a big concern in many American communities. I hope my work will help local decision-makers understand the tradeoffs involved with different policy directions.

A lot has been portrayed lately in the media-with a sense of urgency-regarding a possible future food crisis and water shortage due to the increasing demands of emerging economies. The world’s water consumption rose sixfold between 1900 and 1995 - more than double the rate of population growth - and keeps on growing as farming, industry and domestic demand all increase, specially in said economies such as India and China. Yet, every species living in the planet needs water for sustenance and it can’t be consumed by some and on the shortfall for others. Farming, which accounts for 70% of the world’s water consumption, is also essential to the life of all humans.

On the other hand, climate change has brought excessive rainfall to some areas and droughts in others affecting farming practices and the food supply chain. While many people have grown aware of the climate change issue, efficient use of water in our home to industrial and agricultural practices still needs to be taken into account. I recently read an article in The Economist that blamed the problem of a future water shortage on bio-fuels and while it correctly pointed out our that one third of the world’s population could be affected by the scarcity of water by 2025 it offered no real solutions to the issue at hand.

Climate change aside, we have to understand that every day activities also affect our fresh-water supplies. This is not a distant problem, but rather one for which every single citizen is responsible. Erosion from incorrect land use provides excess sedimentation which in turn diminishes our reservoirs accumulation capacity while introducing pollutants that affect not only water quality but ecosystems as well. According to the U.S. Natural Resources Conservation Service soil runoff can impact, directly or indirectly, water quality and water usage. Surface and stormwater runoff from urban activities also impact our rivers and lakes by delivering pollutants into them.

In my six years at EPA I have participated in countless beach, lake and river cleanups. The amount of trash and sediment from illegal dumping that goes into our water bodies might surprise anyone who has not seen it. Large toys, stoves, tires, construction materials and even cars, just to name a few, all have been retrieved from our reservoirs, creeks and rivers. Education is the key to prevent a water shortage in the future. After all water is finite and we all need it.

Informes presentados recientemente por los medios de comunicación advierten con sentido de urgencia acerca de una potencial crisis por escasez de alimentos ligada a una escasez de agua debido a las demandas cada vez mayores de las economías en desarrollo. El consumo de agua en el mundo aumentó exponencialmente-entre 1900 y 1995-más del doble del crecimiento poblacional y sigue en aumento debido a la creciente demanda que tiene para usos industriales, comerciales y agrarios en las economías antes mencionadas como India y China. Todas las especies en el planeta necesitan agua para vivir y no podemos segmentar su uso. La agricultura, que consume el 70% del agua a nivel mundial, es también esencial para nuestras vidas.

Adicionalmente, el cambio climático ha traído exceso de lluvia en algunas regiones y sequías en otras, lo que ha afectado la agricultura y la cadena de alimentos. Aunque muchas personas conocen sobre el cambio climático, el uso ineficiente del agua en nuestras casas, industria y agricultura también ha impactado adversamente nuestros abastos de agua. Recientemente leí un artículo en la revista The Economist en el que se culpaba a los bio combustibles por las posibles carencias de agua en el mundo. Aunque ciertamente planteaba que un tercio de la población mundial sufrirá por escasez de agua en el 2025, este artículo no ofrecía soluciones reales al problema.

Dejando el cambio climático a un lado, tenemos que comprender que son nuestras actividades diarias las que afectan nuestros abastos de agua dulce. Este no es un problema distante o ajeno, más bien uno sobre el cual cada ciudadano es responsable. Por ejemplo, la erosión ocasionada por el mal uso de la tierra puede causar sedimentación, lo que a su vez reduce la capacidad acumulativa de nuestras reservas. Esto también arrastra contaminantes que afectan no sólo la calidad de nuestras aguas sino también nuestros ecosistemas. De acuerdo al Servicio de Conservación de los Recursos Naturales de los Estados Unidos  las escorrentías impactan, directa o indirectamente la calidad de nuestras aguas y su uso. Los contaminantes de las escorrentías urbanas también impactan adversamente nuestros ríos y lagos.

En mis seis años en la EPA he participado de muchas actividades de recogido de basura en playas, lagos y ríos. La gran cantidad de basura y sedimento que llegan de forma ilegal a nuestros cuerpos de agua no debe sorprender a nadie. Juguetes grandes, estufas, llanta, materiales de construcción e inclusive autos, por nombrar algunos, han sido sacados de nuestras reservas, quebradas y ríos. La educación es la solución para prevenir una escasez de agua en el futuro, real o potencial. Todos podemos hacer algo para proteger este valioso recurso. Después de todo el agua es limitada y todos la necesitamos para vivir.

One of the “gifts of the season” we usually overlook is the amount of STUFF we have left over - food scraps, dead batteries, old fir trees, and more.  But most of these things can be recycled or reused in some way, or at least disposed of properly.

How will you handle holiday waste?
