Scott,
Typically the farther west you go your way from me the iron levels drop but manganese goes up according to the test well data I have. There are exceptions though. My well driller that really knows his stuff warned me my iron level could rise if in put in a larger pump.
On an interesting note the high school down the road has very little iron, but across the highway two houses down in the direction of the high school a Cuuligan technician told me a household has twice as much iron as I do. (5 ppm)
According to a map I have the highway in front of me divides the Soloman Creek aquifer and the the Natural Lakes aquifer. I'm supposed to be on the side of the Natural Lakes aquifer.
