Camp Lejeune water contamination and PD.
I arrived at Camp Lejeune, NC in Oct. 1981. I was assigned to the 2d Marine Regiment. This was my home from Oct. 1981 to Jun. 1984. I heard about the contaminated water (http://www.marines.mil/clwater) sometime in 1981, but I paid little attention to the things I could not control for myself at the time.
I was further exposed to one of these contaminants (Trichloroethylene) while working as a civilian at the Naval Air Warfare Center Indpls and Hughes Aircraft Indpls from 1987 to around 1996.

Dr. Samuel Goldman (Parkinson’s Institute in Sunnyvale, California) looked at 99 male twins, one of which had Parkinson's disease
(http://www.thepi.org/index.php?src=n...icles&refno=14). Apparently, the significant "difference" between each of these twins was exposure to "trichloroethylene" (TEC). The twin exposed to TCE has Parkinson's, while the twin NOT exposed to TCE does not have Parkinson's.

Dr. D.M. Gash et.al. (University of Kentucky) (http://www.ncbi.nlm.nih.gov/pubmed/18157908) has found a link between chronic exposure to TCE and Parkinson's disease. This study looked at 30 workers at one industrial setting. It found that the three workers subjected to chronic inhalation and dermal exposure to TCE had Parkinson's disease, while coworkers more distant from the exposure displayed features of parkinsonism (including significant motor slowing).

YOUR opinion--how much more evidence do we need to establish "cause and effect"?
Thank YOU.
