Best spring water brand - mineral content

I was curious which spring water brand would be the best to use for brewing, I have found three interesting web sites which contain data, one which is limited to only a few brands though. Two of these sites list mineral content and one site lists contaminations found in bottled spring water such as harmful bacteria and arsenic, I'm sure that there are other sites as well for a more complete list of brands and their minareal content. etc.

Anyway I was curious of what you all thought might be the better brands and for which beers and for what reasons. since currently I am only brewing with %100 spring water. (Cost is no object at this point for me, maybe later after I have perfected what I'm looking for)

Here are the three sites I,ve found.

Thank you for your research. I tried to find some of this info a few months back and was unsuccessful. I also use bottled springs water and have used Arrowhead and Crystal Springs the most..they are usually what I cn find around my location readily... After reading these reports though, I guess of the 2 I usually use, I will no longer be using any Geyser Springs. With that said I've pretty much used them in just about all the styles except IPA's.. which I don't usually care for... and would have to say that my darker styles..ie..Stouts, Porters, Scottish ales have always come out the best. Of course, I will also have to say that I prefer the darker styles so might be somewhat prejudiced. If you find anymore bottled water referencesplease pass them along. Good luck and happy brewing
