None, but you must understand that distilled water has no buffer 
capicity whatsoever.  A ph drop of 0.8 in distilled water is caused by 
much less CO2 than what it would take to lower the pH of tapwater. 
Either that or CO2 is more soluble in distilled water.

Simple experiment:  Put your distilled water, and your tapwater under 
aeration and measure the pH.  The deionized water in my lab usually 
rings in at a pH of 4.5 wheras the tapwater is about 7.1.
