CHARLESTON, W.Va.—West Virginia officials investigating reports of a powder in the air and on some vehicles in the mid-Atlantic have determined the source: pollen.
Final results from the dust samples collected Friday in the state’s Eastern Panhandle indicated the material is predominantly pollen, with trace amounts of mineral matter, the West Virginia Department of Environmental Protection said in a statement Monday. The samples were analyzed by West Virginia University’s Department of Geology and Geography.
