One thing to keep in mind when searching is what happens around you and upstream from you. Pueblo is bottom of the river, so all the big ag that happens between there is what makes the water shit. The farther down you are, the more shit gets in the water...Just look at the algae blooms at the mouth of the Mississippi. All that is from the N runoff in the big ag. I've seen wells in the metro area at 600 ppm.
But mountain water can be shit too, depending on where you are. It doesn't all run through limestone caves on it's way to you.
Well rights (the amount you can draw) will be different based on WHEN the well was built, acerage owned, rights inherited/purchased, WHERE you are (since these rights were bought and sold a hundred years ago, lots of the senior rights are in the plains or neighboring states).
If buying 35+ acres then you can usually have up to an acre in cultivation with a home well. That will vary. I looked at a place between Fairplay and Hartsel where you were allowed five acres of cultivation (but good luck, that's Yak/Cattle country out there).
Always worth a water test if buying, if renting bring your pH meter (or grab a water sample and take home) to at least get what your starting pH and ppm are. A little educated guessing can go a long way.
If you RO, then some of these mountain wells may be pushed to the max, and you have to get creative (like using the RO waste water for other purposes).
TG: Water is a long subject and without knowing some of your needs, hard to say. Shit water isn't shit water if you have planned for it and are running it into an appropriate organic system. Hydro, you can get a lot out with cascading carbon/sediment filters, a friend uses some 1 micron filters from the Home Depot that drop his ppm 200-300 from original. A shit (flow) well in the mountains could be 100-200 gallon a day. If it's yellow, let it mellow.
Also, you'll want to know the cistern size, I'd be wary of anything under 500 gal for 1 person and 1 grow, otherwise you might be getting crazy with timers and tanks. A 30 minute shower can use 80 gallons or more.
When deciding separate water needs and wants, just in case that bitching house in the right spot is great, but you have to live like a granola to be there with your ladies.
