In some publications, Wilson's Disease is listed as a health effect of copper. Does copper in
drinking water actually cause Wilson's Disease?
Response:
No. Wilson's Disease is an inborn disorder with copper metabolism, and is not caused
by copper in drinking water. Rather, individuals born with Wilson's Disease are at a
higher risk of experiencing toxic health effects due to copper metabolism, allowing
accumulation of copper in the liver, brain, kidneys, and corneas causing hemolytic
anemia, neurological disorders and cornea opacity (56 FR31516). Also, the mandatory
health effects language in 141.32(e)(14) of 56 FR 26460 (June 7, 1991) states that copper
at high doses has been shown to cause stomach and intestinal distress, liver and kidney
damage, and anemia.
