Government estimates now say up to a million people living and working at Camp Lejeune may have been exposed to harmful chemicals in the water supply.
That from U.S. Senator Elizabeth Dole's office as she announced the senate has approved an amendment that helps notify those exposed.
Dole's amendment would require the Navy to notified Marines and their families who lived at Lejeune between 1958 and 1987 that they were exposed to harmful chemicals in the base's water system.
The wells were shut down in 1987, but Dole says the Marines knew as early as 1980 that there were problems with the water.
