North Carolina State University researchers have developed a computer model that will accurately predict stormwater pollution impacts from proposed real-estate developments – allowing regulators to make informed decisions about which development projects can be approved without endangering water quality.
The model could serve as a blueprint for similar efforts across the country.
“The model is designed to evaluate the amount of nitrogen and phosphorus found in stormwater runoff from residential and commercial developments – particularly runoff from a completed project, not a site that is under construction,” says Dr. Bill Hunt, an associate professor and extension specialist of biological and agricultural engineering at NC State who helped develop the model. “To comply with regional water-quality regulations, cities …
