I found out 7 years after my diagnosis of "Ataxia/2006" 2013 USMC base Camp Lejeune newspaper article, toxic drinking water from 1953-1987..........more like 1940's to present. Lead plumbing still in drinking water. VA addresses 4 toxins TCE, PCE, Benzene and  Vinyl Chloride.........................on NPL there are 51 different chemicals in drinking water at 34 different sites.
