Owning an island is easier than you might think, that is–a floating island. This man-made ecosystem mimics naturally occurring wetlands and has the ability to clean water while providing the same ecological benefits as natural wetlands. Dr. Joshua McGrath, assistant professor at ENST and alumnus Kevin Hedge are exploring the nutrient removal effectiveness of floating islands in poultry stormwater ponds on the Eastern Shore of Maryland.
Initially developed to control water quality in aquatic microcosms in the early 1980s by Dr. Walter Adey at the Smithsonian Institution, Algal Turf Scrubber™ technology has been studied and refined...
Growing up in Oregon, Dr. Stephanie Yarwood dreamed of studying whales. Currently, an assistant professor of environmental microbiology in the Department of Environmental Science and Technology (ENST), she still has not forgotten about whales, but when asked about her shift of interest, she replies: “microbes are way more powerful!”
Dr. Bahram Momen, an associate professor in biostatistics and ecosystem ecology, received a Water Resources Competitive Grant of $200,000 through a joint program between the National Institutes for Water Resources and the U.S. Army Corps of Engineers. He intends to use the grant to revolutionize the way we quantify and communicate flood risk management.
As sunlight rose across the Potomac River on September 23rd 2011, it did not trace the typical blades of grass and ball fields in west Potomac park as it did seven days earlier. Instead, the sun...
The University of Maryland beat out 21 other colleges and universities from around the country to take home the top prize in the National Collegiate Soil Judging Contest hosted by the University of...
It was an old and dying oak, belonging to his grandfather, that inspired soil science doctoral student David Ruppert to grow oaks from acorns. What started as a 175-acorn-trial in the University of...
Did you ever imagine that radishes could be used to produce renewable energy? No one saw it coming. However, Dr. Stephanie Lansing and Dr. Ray Weil in the Department of Environmental Science and Technology are testing dairy manure and forage radishes to develop a new technology that could enable corn silage-based dairy farmers to reduce greenhouse gas emissions, nutrient runoff, and environmental impacts while producing a renewable biofuel.
From Louisiana to Maryland, from Delaware to New Jersey, the world’s most valuable ecosystem- coastal marshes, are threatened by sea level rise. An experienced team of faculty and graduate students from the Department of Environmental Science and Technology (ENST) are studying Chesapeake Bay coastal marshes along the Nanticoke River and at Blackwater Wildlife Refuge.
Environmental Science and Technology undergraduate student Grant Hughes-Baldwin satisfied both his love for travel and his passion for marine ecology by studying abroad for a semester at the...
Newcomer to the Department of Environmental Science and Technology and a native of New Zealand or Kiwi , Dr. Paul Leisnham brings his latest research on mosquitoes and human health from ‘down under’...
Everyone loves a good mystery. Dr. Raymond Weil is no exception. However, this detective isn’t looking for “who dunnit” but rather how it can be done better. Weil, a professor of soil science at the...
Dr. Joshua McGrath , an assistant professor in the Department of Environmental Science and Technology, has been awarded the 2010 Inspiring Young Scientist Award from the American Society of Agronomy...
Poultry litter and human biosolids have been commonly used as fertilizers for decades. However, at the Wye Research and Education Center, aquatic toxicologists Dr. Lance Yonkos and Dr. Daniel Fisher are studying the environmental fate and effects of contaminants found in these fertilizers.
Water, the world's most precious resource, will soon get a breath of fresh life thanks to graduate student David Blersch's research into wastewater treatment methods. An ecological engineering graduate student in the Department of Environmental Science and Technology (ENST), David is designing a new computer-based system that will treat wastewater via an algal turf scrubber treatment.
ENST graduate student Jennifer Brundage examines the effectiveness of grazing by goats to control common reed, an invasive wetland grass known as Phragmites Australis.
Department of Environmental Science and Technology undergraduate student Diane Peng has been chosen as a 2011-2012 Merrill Presidential Scholar. Diane recognizes her mentor, Dr. Andrew Baldwin , as...
