The Dan River flows 214 miles (344 km) in the U.S. states of North Carolina and Virginia. It rises in Patrick County, Virginia, and crosses the state border into Stokes County, North Carolina. It then flows into Rockingham County. From there it goes back into Virginia. It reenters North Carolina near the border between Caswell County and Rockingham County. It flows into northern Caswell County and then back into southern Virginia and finally into Kerr Reservoir on the Roanoke River. The name of the river comes from the Saura word for otter, "ptan", which sounds like "Dan" in pronunciation.
A variant name is South Branch Roanoke River.
Coal ash spill
In 2014, tens of thousands of tons of coal ash and 27 million gallons (100,000 cubic meters) of contaminated water spilled into the Dan River near Eden, NC from a closed North Carolina coal-fired power plant that is owned by Duke Energy. It is currently the third worst coal ash spill ever to happen in the United States. A 48-inch (120 cm) pipe spilled arsenic and other heavy metals into the river for a week, but was successfully plugged by Duke. The federal government plans to investigate, and people along the river have been warned to stay away from the water. Fish have yet to be tested, but health officials say not to eat them. Cities in Virginia which use the river say that with standard methods of treatment, the water is safe to drink. Ash is found on the bottom of the river for 70 miles (110 km) and is as much as 5 feet (150 cm) deep in places. Late in February, North Carolina regulators cited Duke for the violations at the plant on the river. On March 3, in addition to citing Duke for similar problems elsewhere in the state, North Carolina's Department of Environment and Natural Resources called the spill on the Dan River an "environmental disaster." On April 18, Duke said three North Carolina State University researchers had determined pollutants were down significantly and that the water was safe for farm uses, as long as recent precipitation had not disturbed sediments. At the same time, Duke was attempting to remove some of the ash in the river. As of November, Duke said it had removed 3,000 tons of ash.
A study by Wake Forest University researcher Dennis Lemly completed in November estimated the cost of cleanup at $300 million. Another study by U.S. Fish and Wildlife Service, Duke, and environmental agencies in both states was to be released in 2015. Also in November, the North Carolina Department of Environment and Natural Resources reported that insects in the water east of the plant "appear to be thriving".
