The federal agency in charge of studying the effects of contaminated water on Marines and their families at a North Carolina base said critical gaps in funding still exist.
The Department of the Navy and the Agency for Toxic Substances and Disease Registry have been fighting for months over the funding of a mortality study at Camp Lejeune.
In a letter Monday, the Agency for Toxic Substances and Disease Registry argued that the study is "the most-time efficient" and valid method of determining the health effects.
The study will determine if there are higher mortality rates for active duty Marines who served at the base during the years that the water was contaminated.
