Duke professor Curtis Richardson, one of Duke's internationally recognized scholars, brings his expertise to North Carolina by removing pollutants from a regional water supply in Durham and improving the local wildlife habitat. Richardson is one of many Duke professors whose research benefits North Carolinians.
It's a common but unfortunate effect of development: Paving over land for shopping centers, subdivisions and the like can cause stormwater runoff that threatens drinking water sources. Curtis Richardson is doing something to remedy the situation.
Richardson, a professor of resource ecology at the Nicholas School of the Environment and Earth Sciences, has been called on to help preserve the Florida everglades and the marshlands in Iraq. The spring, Richardson focused his talents at home, supervising the transformation of about 2,000 feet of heavily eroded, silt-clogged Sandy Creek in Duke Forest into a restored wetland. Once refurbished, the wetlands will treat about 1,400 acres of stormwater runoff from Durham and the Duke campus, removing sediment and nutrients before the water drains into the Jordan Reservoir, a drinking-water source for thousands in the Triangle.
"By restoring the natural flood plain that used to be here before the onslaught of urban development, we'll recreate a healthy wetlands ecosystem that sops up pollutants and improves wildlife habitat," says Richardson, founder and director of the Duke University Wetland Center. "Our goal is to create an ecosystem similar to what you would have found here 75 to 100 years ago."
Project sponsors include the Clean Water Management Trust Fund, the North Ecosystem Enhancement Program, Duke Forest, Duke's Facilities Management Department EPA 319 Program, and the Wetland Center. The reconstruction will take about six months and cost $ 1.5 million dollars. EPA 319 Program will also provide an additional $340,000 for monitoring and construction of treatment wetland at the site over the next three years.
Lessons from the restoration will contribute to a better understanding of what to do elsewhere in the state, says Bill Holman, executive director of North Carolina's Clean Water Management Trust Fund. The fund, created in 1996 by the N.C. General Assembly, makes grants to local governments, state agencies and conservation non-profits to help finance projects that address water pollution problems.
"With most of these restoration projects, we're still in the art, not the science, phase," Holman says. "We're still learning a lot about what really works and what doesn't. [Duke's] wetlands research project is a win for water quality and a win for improving the science of stream and wetland restoration."
Besides being an example of a rare Piedmont wetland, the eight-acre ecosystem provides a site for research on biological diversity, hydrology, mosquito control, invasive plant species and other environmental concerns, Richardson says. The project will serve as an outdoor classroom and field laboratory for students and researchers from Duke and other area schools and universities.
"What we learn here will reach far beyond Durham," adds Richardson. "It will benefit wetlands and watersheds nationwide."
