I notice that Jon lives in a hotspot - Arizona - and that could be useful. Depending upon your free-time and DIY skills, it might be pragmatic and cost-effective to build/make a solar still. While it is super-easy to do, it can also be as much as a work of art if you wanted it so, but the end product would be the same - neutral water that is as near ideal for hydroponics as you're gonna get. There's plenty of info on the 'net about solar stills, so fill yer boots! Plus, you should have an air-con by law in Arizona (at least Wiki says so), and you could use the huge amount of condensate for your plants which in its natural state is ideal for hydroponics- just watch that the waste water doesn't exit out of rusty pipes and use a good sieve/filter if necessary to ensure clean particle-free water (but check for tds first if you think your pipes are suspect).

Collect Rain Water? by: Jerry Morse
To the person who had a high well water pH. Maybe this person should consider catching rain water and using it instead of well water for plants.
