Although I am conscientious about treating surface water before drinking it, is there any danger with drinking untreated water if it comes out of the ground (for example, a spring) and there is no development or agriculture at a higher elevation?.

The official stance of the Wilderness Medical Society is this: Treat all water from wilderness sources—better safe than sorry. On the other hand, it is likely that water emerging from a spring at higher elevations will be safe. The final decision, of course, is yours. —Buck
