A federal judge has again refused to dismiss a lawsuit filed by an Iowa woman who claims contaminated water at Camp Lejeune in North Carolina contributed to her cancer.

U.S. District Court Judge Terence Boyle this week denied the federal government's motion to end the litigation filed by Laura Jones.

Jones used contaminated water during the 1980s while her husband was stationed at the Marine Corps base. She was diagnosed with non-Hodgkin's lymphoma in 2003.

The government argued state law prevents a claim because the contamination took place more than 10 years after her illness. But Boyle said there's an exception for latent diseases.
