Subject: Must I need distilled water for my rusting of nails experiment?

I am currently conducting an experiment that calls for a nail to 
be put in a soil and water mixture and a nail in just plain 
water that has been sterilized. The nail in the soil mixture 
should rust more quickly than the nail in the water. For the 
water, i used plain tap water, but the nail seemed to 
disenigrate very quickly. I am wondering if distilled water 
would prevent that because it has no chemicals in it such as 
chlorine.
