Garden beds filled with native plants, parking spots reserved for fuel-efficient vehicles and plant-covered roofs that trap rainfall before it runs into storm drains: these simple steps to “go green” have turned a Southern Maryland community college into a model of conservation.
Located less than five miles from the Patuxent River, the College of Southern Maryland’s (CSM) Prince Frederick campus has become home to a green building that shows students and citizens alike the benefits of green infrastructure.
Indeed, green building has become the norm for new facilities in a state that has long championed smart growth and all that it entails, from funding development inside of existing communities to protecting rural areas from suburban sprawl. Maryland legislation passed in 2008 even requires building projects of a certain size to be certified as green, whether it is through the Leadership in Energy and Environmental Design (LEED) Green Building Certification program or the Green Globes system. At 30,000 square feet, the academic building in Prince Frederick fit the bill of needing to be green.
“[Earning green certification] was a mandate from the state,” said Richard Fleming, CSM vice president and dean of the Prince Frederick campus. “It’s a laborious process, but it has also been exciting, because I had never worked with [a green building] before.”
Fleming has worked with community colleges for 35 years, and was until 2009 the vice president for academic affairs at Thomas Nelson Community College in Hampton, Va. The chance to construct a new building on the fastest-growing campus in the CSM network attracted him to this new position at his sixth college in as many states.
Opened in September and funded in part by the state, the Prince Frederick building is the second LEED-certified building in Calvert County. According to the U.S. Green Building Council, which operates the LEED certification program, green buildings can lower energy use and operational costs; reduce waste and carbon emissions; and provide healthy indoor spaces for building occupants. These are all benefits that Fleming hopes to see.
“The goal behind LEED is to one, reduce water consumption, and two, reduce energy consumption,” Fleming said. “We should, after a period of time… start to see some kind of gas savings, electrical savings, energy savings.”
To earn LEED certification, building projects collect points based on different aspects of their construction. The higher their final score, the higher the certification level earned. Fleming hopes that the Prince Frederick building will reach gold status, and gave us a tour of some of the items on its green building checklist: large windows that flood the space with natural light; green roofs that capture rainfall; bike racks that encourage public transportation; bio-retention cells that collect stormwater from sidewalks and parking lots; and native, drought-tolerant plants—like black-eyed Susans, American beautyberry and Joe-Pye weed—that fill up garden beds.
Students and faculty “are all very pleased with [the new building],” Fleming said. But it is not just the campus that will benefit.
“This is a building that’s open to the public,” said Dorothy Hill, lead media relations coordinator for CSM. The campus has hosted film festivals and concert series, and the new building’s 3,000-square-foot meeting space has been called the best in Calvert County.
“At the dedication, people were very interested in learning what LEED certification was all about,” Hill said. “The community comes here, and will be able to see… that we’re stewards of the environment, and we care about the community.”

The oldest body of seawater ever identified is buried under the Chesapeake Bay.
According to the U.S. Geological Survey (USGS), this recently discovered body of water dates back to the Early Cretaceous period, when wet and dry seasons controlled the climate, tropical jungles dominated the landscape and dinosaurs were becoming more plentiful.

The water is buried beneath a large meteorite that struck the earth 35 million years ago, throwing debris into the atmosphere and spawning a train of tsunamis that probably reached as far as the Blue Ridge Mountains. The so-called “Chesapeake Bay impact crater” is the largest crater discovered in the United States and helped determine the current shape of the Bay.
Because the water is trapped in place, USGS scientists have been able to estimate its age—100 to 145 million years old—and its salinity—twice as salty as modern seawater.
Acting USGS Associate Director for Water Jerad Bales said in a media release that before this discovery was made, no one realized that the saltier-than-normal groundwater found deep in the Atlantic Coastal Plain “was North Atlantic ocean water that has essentially been in place for 100 million years.”
“We are working directly with seawater that dates far back in earth’s history,” Bales said.
Slow-moving groundwater on the Delmarva Peninsula could push excess nutrients into the Chesapeake Bay even after we have lowered the amount of nitrogen and phosphorous we put onto the land.

According to new research from the U.S. Geological Survey (USGS), most of Delmarva is affected by the slow movement of nutrients from the land into the water. A USGS model developed to track the movement of nitrogen through the region showed that groundwater—and the pollutants it can contain—takes an average of 20 to 40 years to flow through the peninsula’s porous aquifers into rivers and streams. In some parts of Delmarva, the groundwater that is now flowing into local waterways contains nitrogen linked to fertilizer used three decades ago.
The slow flow of nitrogen-laden groundwater into the Bay could affect efforts to restore the watershed, lengthening the “lag-time” between the adoption of a conservation practice and the effect of that practice on a particular waterway. In other words, it could take days or even decades for today's management actions to produce positive water quality results.
“This new understanding of how groundwater affects water-quality restoration in the Chesapeake Bay will help sharpen our focus as many agencies, organizations and individuals work together to improve conditions for fish and wildlife,” said Lori Caramanian, Department of the Interior Deputy Assistant Secretary for Water and Science, in a media release.
While these findings seem to contradict the value of our restoration work, the study in fact indicates that pollution-reducing practices put in place over the past decade have begun to work. The study also confirms that rigorous steps taken to reduce nutrients on the land will lower the amount of nitrogen loading into streams in the future.

Between fast food restaurants and speed-of-light cell phones, we live in a culture of instant gratification. But the environment around us doesn’t operate that way. Instead, it is slow to respond to changes—like the upsets or imbalances created by human activity.
Scientific evidence shows that many of the pollution-reducing practices we are placing on the ground now may take years to show visible improvements in water quality. One reason? Pollutants can be persistent. French and Canadian researchers, for instance, tracked the movement of fertilizer through a plot of land over the course of three decades. While more than half of the fertilizer applied to the land in 1982 was absorbed by agricultural crops like wheat and sugar beet, 12 to 15 percent remained in the soil. The researchers predicted it would take an additional 50 years before the fertilizer fully disappeared from the environment.
Much of the farmland in the Chesapeake Bay watershed sits over groundwater, now contaminated with high levels of nitrates following years of fertilizer applications above ground. Work by the U.S. Geological Survey (USGS) has shown that it will take a decade for this nitrogen-laden groundwater to flow into rivers, streams and the Bay. On the Delmarva Peninsula, where deeper, sandy aquifers underlie the Coastal Plain, this so-called “lag-time” could take 20 to 40 years.
So what implications could lag-times have for the Bay restoration effort? Last year, the Chesapeake Bay Program’s Scientific and Technical Advisory Committee (STAC) released a report about the lag-time phenomenon. The team of experts concluded that lag-times will affect public perception of our progress toward meeting the pollution diet set forth by the Chesapeake Bay Total Maximum Daily Load (TMDL).
The TMDL requires the six Bay states and the District of Columbia to implement their proposed pollution-reduction measures by 2025. There may be an expectation on the part of the general public and our elected officials that once these measures are fully implemented, the Bay will have met its water quality goals. But now we know that it may take some time before we can make that claim. As 2025 approaches, we must remind the public that lag-times exist and ask for their patience in seeing a healthy Bay. Because through patience—and vigilance—the Bay will be restored.
