Federal environmental officials say a fresh round of testing has found no chemical contamination under housing used by military families at Camp Lejeune.
The U.S. Environmental Protection Agency and the Marine Corps say a network of monitoring wells didn't find any chemical contamination under a school and base housing from a nearby Superfund site.
Base officials closed several wells in 1987 that were contaminated with solvents from a dry cleaners across the street from the Tarawa Terrace I base housing complex. Government figures estimate that up to 1 million people were exposed to the chemicals.
In July, base officials notified residents of nearly 900 homes that testing was under way conducted.
