I just read another article about this, but the affected group is military from Camp Legume. The water in Legume was contaminated, and its actually given a control group test for the incidence of Parkinson’s with Camp Pendleton, where the water was not contaminated.
Spoiler: it looks like the farmers are right

Amazing thing is TCE was banned by the Biden EPA in 2024 and Trump’s EPA stopped its ban.
Minor correction: it's Camp Lejeune. I just had to chime in because Camp Legume is both very funny and kind of an appropriate typo for the topic.
For anyone stopping by looking for more info, it’s Camp Lejeune not Legume.
