Toxic Contaminant in Water Linked to Sharp Increase in Parkinson’s Risk

A new study of over 300,000 veterans found a strong connection between contaminated water at Marine Corps Base Camp Lejeune, North Carolina, and a higher risk of developing Parkinson’s disease. The research, published Monday in the journal JAMA Neurology, concluded that the risk of Parkinson’s was 70 percent higher in Camp Lejeune veterans than others stationed at a different Marine Corps base on the opposite side of the country in California.

The study included over 300,000 service members. Those stationed at Camp Lejeune were there for at least three months between 1975 and 1985. Even veterans who were not diagnosed with Parkinson’s disease still had “significantly higher” risk for early signs and symptoms of the illness, the researchers reported in the study.

The study’s researchers link the increased risk of Parkinson’s with exposure to trichloroethylene, which, according to the Centers for Disease Control and Prevention, is a colorless cleaning chemical with a chloroform-like odor. The Agency for Toxic Substances and Disease Registry notes that the chemical was first discovered in Camp Lejeune’s drinking water – specifically water from the Hadnot Point treatment plant – in 1982. Both Veterans Affairs and the Department of Defense have previously acknowledged the exposure of trichloroethylene at Camp Lejeune.
