Shelby Township resident James Fontella is a breast cancer survivor who believes contaminated water at the Camp Lejeune military base in North Carolina caused his illness. The Marines are trying to determine whether he and 3,346 other Michiganders with various illnesses are correct about a possible link. They are among 144,000 people nationwide participating in a study on the health effects of drinking water at Camp Lejeune between the mid-1950s and the mid-1980s.
