BURLINGTON — U.S. Army Environmental Command officials will hold a public open house on June 27 about the ongoing environmental work at the former Tarheel Army Missile Plant in Burlington.

The 22-acre plant at 204 Graham-Hopedale Road, also known as the former Western Electric site, has been unused for years, but contamination includes solvents, benzene and two types of PFAS chemicals. Since the mid-1990s, the military has spent upward of $2 million remediating the contamination, but a full cleanup never happened.
