The study relied on models and was not able to measure how much tainted water those surveyed consumed, and therefore could not gauge how much of the chemical they may have been exposed to. The study also did not look at the health effects on adults that drank the water. Eighty-two men with Lejeune ties have been diagnosed with an extremely rare form of breast cancer.
The study contradicts the longstanding position of the military, which for decades has issued public statements downplaying the health risks to Marines and their families.
Records reviewed by The Associated Press show military authorities continued to rely on the wells for years after testing suggested the water was contaminated. The most highly contaminated wells were closed in 1984 and 1985, after a round of more extensive testing found dangerous concentrations of toxins associated with degreasing solvents and gasoline.
