Virginia Tech researchers study how to clean up Gulf oil

Virginia Tech College of Engineering researchers have received a $60,000 one-year National Science Foundation grant to study how naturally occurring microbes can best be used to eat away remaining crude oil spilled in the Gulf of Mexico. Their choice of weapon: Geometry. Fueled by oxygen, naturally occurring bacteria can slowly destroy blobs and slicks of crude oil without the use of additional chemicals. Faculty researchers at Virginia Tech’s Charles E. Via Jr. Department of Civil and Environmental Engineering<http://www.cee.vt.edu/> (http://www.cee.vt.edu/) hope to determine if the shape of crude oil remnant – be it a flat syrupy sheet or a tar ball – can affect deterioration rates. The researchers also will study how a lack of oxygen can hinder microbe growth, and how carbon leaching from dissipating oil can further fuel these oil-eating microbes, a two-step process known as mass transfer and biodegradation. Remaining toxic chemicals left behind by the spill also will be studied at Virginia Tech labs in Blacksburg. “This research has the potential for improving our understanding of the long-term persistence of chemicals in the environment. In terms of clean up, there are many problems left to solve regarding the most toxic and recalcitrant pollutants that dissolve out of liquid sources, not just associated with oil spills, but at industrial sites, etc.,” says Mark Widdowson<http://www.cee.vt.edu/index.php?do=view&content=0&apps=2&level=2&id=17&pid=18ced79c659fcda0f2ec097f7043e9c6> (http://www.cee.vt.edu/index.php?do=view&content=0&apps=2&level=2&id=17&pid=18ced79c659fcda0f2ec097f7043e9c6), professor and assistant department head. He is spearheading the research with Amy Pruden-Bagchi<http://www.cee.vt.edu/index.php?do=view&content=0&apps=2&level=2&id=17&pid=ea764b3d7ce4e619692fc864f6a5d628> (http://www.cee.vt.edu/index.php?do=view&content=0&apps=2&level=2&id=17&pid=ea764b3d7ce4e619692fc864f6a5d628), associate professor of civil and environmental engineering. Widdowson and Pruden-Bagchi stipulate that oil remnants that have the geometric shape of flat surfaces will dissipate slower compared to tar balls that can be “surrounded” by microorganisms. “Each has a unique geometry where the rate of dissolution is controlled by exposed surface area,” Widdowson and Pruden-Bagchi wrote in their grant proposal. “For oil layers, aerobic biodegradation on the underside of the deposit will be severely limited by oxygen availability." More than 200 million gallons of oil is estimated to have spilled into the Gulf after the April 20 blowout at BP’s Deepwater Horizon, an incident which also killed 11 people. More than 500 miles of shoreline is affected along the Gulf Coast, which “underscores the urgent need for research that will lead to accurate predictions of the long-term persistence of the crude oil in coastal environments,” the researchers wrote in their proposal. Unknown is how much oil remains hidden along the ocean sea shore, and how the various chemicals used to more quickly disperse massive bodies of crude oil will affect future oxygen levels. If oxygen levels remain low in high-chemical-use areas, microbes likely will not grow fast. Remaining crude oil buried by sand, attached to debris, or trapped in grasses can remain for years. “There are some reports in Alaska, where you can dig a few inches in the ground and find oil left over from the Exxon Valdez spill,” said Pruden-Bagchi of the 1989 incident that spilled anywhere from 11 million to 32 million gallons – numbers vary by source -- of crude oil in the Prince William Sound. “Limited oxygen is a big part of the problem.” Before the grant was officially awarded, Widdowson and Pruden-Bagchi led a student team to the lower coast of Alabama to collect samples in late July. Additional funding for this trip and the study came from two Virginia Tech research programs, the Institute for Critical Technology and Applied Science<http://www.ictas.vt.edu/index.shtml> (http://www.ictas.vt.edu/index.shtml) and the Institute for Society Culture and the Environment<http://www.isce.vt.edu/> (http://www.isce.vt.edu/). In Alabama, along oxygen-rich beaches, they found no large oil slicks or massive tar balls, but smaller chunks of oil with the texture of soft licorice. In oxygen-poor wetland areas, thick, sludgy raisin-shaped balls of oil are still being reported. The researchers already have received assistance from the U.S. Coast Guard and the Environmental Protection Agency in surveying and sampling the crude oil. “Most of the remaining oil will end up in the marshes and on the sea floor, and may not be obvious as it is on the beaches,” said Pruden-Bagchi. Future trips to the Gulf coast are planned. Widdowson and Pruden-Bagchi are focused on sharing the information with those handling the Gulf Coast disaster and future oil spills, but also plan to submit their findings for publication in peer-reviewed scientific journals.  Pruden-Bagchi also conducted an oil spill clean-up activity for regional middle school students through Virginia Tech’s Imagination summer camp, held in July. Both lead researchers are familiar with the Gulf Coast. Pruden-Bagchi’s spouse has relatives conducting research at Mobile’s University of South Alabama, while Widdowson has lived in Alabama. “My wife and I both attended Auburn University and occasionally managed to slip away to the Gulf beaches, including Gulf Shores. We were attracted by the beauty of the white sand and crystal clear ocean.”

Amy Pruden-Bagchi and Mark Widdowson, on faculty at Virginia Tech's Charles E. Via Jr. Department of Civil and Environmental Engineering, are studying how geometry can help in dispersing oil spills quickly and safely.

Cutler backs transferring Explore Park to National Park Service

Rupert Cutler — former Roanoke city councilman and former Explore Park director — speaks today to the the Roanoke Council of Garden Clubs.

Cutler gives this preview:

“I’ll suggest they ask City Council to close Wylie Drive to vehicular traffic because of the biker/runner/walker/stroller traffic congestion there now, and the danger to pedestrians of cars and trucks close by, while suggesting that the facilities at new Vic Thomas Park, easily accessed off 13th Street/Memorial Avenue, be tailored to meet the needs of the handicapped citizens who now need to drive to Smith Park.

“I’ll urge them to support the transfer of Explore Park to the National Park Service to become part of the Blue Ridge Parkway, to protect the environment and historic buildings in Explore and make it part of the most-visited National Park System unit in the country, to benefit the local economy.

“I’ll bring to their attention their opportunity to partner with the City parks department by helping to maintain the planters along Wylie Drive that currently look abandoned. They need gardeners’ TLC.

I’ll note the continuing role of the Kiwanis Club of Roanoke in paying for and installing mile posts and environmental and historical interpretive signs along the Lick Run and Roanoke River Greenways and the Kiwanians’ intention to help make the greenways “outdoor classrooms” to meet the challenge of Richard Louv in his book, “Last Child in the Woods: Saving Our Children From Nature-Deficit Disorder.”

“I’ll point out that Lucy Ellett should be regarded as the god-mother of our greenway system.”
