Beersmith gives you a list of cities. I think we're talking about a list of basic styles.

RO is great as long as you want to build your water. This is what I do and I love it.

Thats a reasonably safe assumption. RO strips about 95% of everything, so if your water is reasonable, it should be pretty similar across the board (sorry phoenix and your 1500ppm tds)

Maricopas well water also has Arsenic and Uranium! so would that mean that if I had an in home RO system, that my filters would be classified as hazardous waste?

I will refute. RO is system dependent and thus will only filter out what that system is capable of when you install fresh filters. Then it degrades in performance until you replace filters. At some point the membranes also need replacing. Not all RO systems are created equal. RO systems also require the correct water pressure to get the most filtering performance.

Therefore I would bet that RO water is rather varied.

samc, after doing a bit of searching today, I think I will agree with you.

Very few of the bottled water suppliers have their WQR online. Still fewer give a detailed report that lists the ions we're interested in as brewers.

The levels of these salts are consistently lower than tap water but the levels aren't that consistent from report to report. In addition, the range of values given within these reports can be so wide they render the entire report useless.

A well maintained RO will strip 95% of pretty much everything. A well maintained RO/DI will strip pretty much everything.

Doing some more homework this morning. The more I read the more I realize how limited my knowledge is on this subject. I imagine those that know WTF goes on with all of this chemistry are sitting on the sidelines getting a good chuckle out of this thread.

I'm new to this whole beer making process...but it sure disappoints me to go back to purchasing drinking water at the store when I invested in the water softener and RO system. My knowledge to is very limited on this subject but I would love to have such a table...
