A cycle stop valve and smaller pressure tank was one of our best investments without going to a VSD.

There is no magic pool of water underground. It all comes from the surface, trickling down through the dirt/rocks. Yes, the same dirt/rocks that your septic leech field dumps into. The regional geology determines the water taste and composition. In Fiji and Iceland, their volcanic rocks make acidic water that people here pay five bucks a bottle to buy. In our area, the deeper aquifer has sulfur-smelling water and the shallower one has a nuisance iron bacteria.

Most local well drillers have records for their drillings in an area, and can give you an idea about the type of water and about how deep it is. Many county health departments have well records for every home/business, if you want to spend a few hours poking around those documents.....
