Most supermarkets carry a decent brand of spring water. Locally it is Arrowhead and they have WQRs listed on their website. Spring water is usually not RO and the WQRs confirm this.
Using bottled water for all grain?

Now there's where the PITA factor comes in. Am I really going to collect 40 gallons of reusable waste water for every 10 gallons of brew water, and further schlep it all over the house for other purposes? I don't think so.
Hey, if someone has the time and space to use an RO/DI system to make brewing water, that's great. I was just pointing out that such a setup isn't as straightforward as turning a knob and quickly collecting several gallons of water on brew day. I had to use one for my reef tank and found it a serious pain. For my time, space, and money, I'll pay .40 a gallon for RO from someone else. But then again I'm a lazy sod.
Well, you do have to go drive to the store to retrieve the water and pay more for it at the same time. You could just dump the waste water down the drain and you're still coming out ahead. "that's wasteful" say the quasi-environmental folks
but when you buy RO water from the store, where do you think their waste water goes?chemman14

why is 3-5 gallons wasted for every 1 gallon of water???

The waste water containing all the solids that are stripped out goes out one tube while the "clean" water goes out another. You get about 3x as much waste water as filtered water. Like I pointed out though, it's not like turning on a hose and getting water in real time. It takes hours to produce 10 gallons of water.
While I'd never bother with it for brewing as I said, if you have the space, time, and inclination it will produce some seriously stripped down water that you can use to build good brew water.
Some of the more expensive membranes will do like a 100 gallons per day so that's 4 gallons an hour. You can get a pressurized membrane tank to hold 5/10 gallons but they are not cheap. It's a lot easier to put a float valve into a barrel/bucket.
When I had a reef aquarium, I just ran the system into the sump tank with a float valve and I never had to top off.

How big was your aquarium? My reef tank was 100 gallons and I was really into the hobby and then...I just lost interest. Nothing worse than losing interest in 100 gallons of reef tank. Talk about a pain to deal with. Never again will I have an aquarium. What a cash vacuum.

Arrowhead gives as good an idea what's in their water as a muni WQR is going to tell you.

No kidding, I only had a 55gal with a 20gal sump and it was a money pit. I was running dual 250w halides for hard corals too so I also had to crank my air conditioning. Luckily I was able to sell it when I needed to move.
