Reptisafe is not going to remove anything other than chlorine out of the water. It won't remove mercury, lead, arsenic, etc etc etc.
I use and always have used RO.
Rain water IS distilled water. Distilled and RO are of similar quality (RO is much easier to DIY than distilling it). Chams drink rain water. 1+1=2
To make a very long story short, here is some further reading

(I see you are from Indiana...the above website tested for 35 chemicals in your water. Found 3 {Total haloacetic acids (HAAs) Total trihalomethanes (TTHMs) Nitrate} and has the audacity to score your water at 9 out of 10......THEN Goes on to say that IT DID NOT TEST for over 184 other dangerous chemicals.) You do the math.

IMO drinking tap water is just asking for 1 in 5 cancer rates, 1 in 5 thyroid problems, and just about every other 1 in 5 chronic disease that has become an epidemic and to put it honestly you're either completely ignorant to it or a complete idiot if you think tap water is safe. Safe is just a euphamism for 'sanitized', it does not mean it is purified.
It's no mystery the only thing that's changed significantly is all the chemicals and heavy metals in tap water. And all the drugs that people take to deal with these disease ends up in the water as well.
(medications are the 3rd leading cause of death in the USA btw, accounting for over 5,000 deaths per day from medications 'taken as prescribed'.)
Sorry I am in the water business and it pains me to see that in 2012 people are still asking if tap water is okay, when every year it is getting worse and worse, not better.
