Artificial-turf fields proliferate in Washington, D.C., area

From The Washington Post: At high schools in and around Washington, D.C., artificial turf is becoming an athletic status symbol. Synthetic ballfields can be found at 10 public high schools in Washington, seven in Anne Arundel County, Md., four in Fairfax County, Va., and three in Arlington County, Va. But debate has emerged in Montgomery County, Md., over such matters as how the turf deals were structured and whether tire crumbs from the fields might contaminate property nearby.
