water from 970 feet down has been filtered by 970 feet of ground, I suppose... =o)

Actually, no. The aquifer is beneath impervious layers. It is filtered by about 40-50 miles of rock, between the well site, and the recharge zone.
The tilt of the beds means that the cap is missing in the recharge area; not that the aquifer layer itself is exposed.
First, the surface water has to percolate down to the aquifer, doing a first-filtration.
Next it spends several years slowly moving, mainly by osmotic pressure, through the miles of fine-grained filtration to the well site.
A few PPM of dissolved minerals, but that's it. The bacteria of surface water rarely get past the first 10-20 feet of surface & sub soils.
