ABC7: Are Montgomery County synthetic turf fields safe for play?

BETHESDA, Md. (ABC7) — Concussions, fractured skulls, broken bones, even death: these are the concerns a trio of civic organizations have raised about the synthetic turf field at Walter Johnson High School.
In 2010, crews installed the faux grass field at the school located roughly half-a-mile east of the Montgomery Mall. However, over time, activists contend the synthetic grass has shed, effectively reducing the once thick green blades to short stubble.
