 At the risk of being trolled I'd say that if deuterium oxide contaminates all 
water at that level then we should be adapted to deal with it.

Deuterium can replace hydrogen in biomolecules however, and it it replaces a 
crucial hydrogen in either an enzyme or enzyme substrate it can slow the rate 
of reaction significantly. I would also be interested to know the effects of 
drinking water with an unusually high deuterium content over a long period. I 
doubt there would be much effect given the low proportion of deuterium and the 
low chance of hitting those critical hydrogens.
