I have a new well, drilled last fall and put into service in February. I've had three water tests done. The first test was done when we were able to get the water in the well to "clear up". The water tested great, was mildly hard, no iron to speak of, no manganese, really just nothing in it. Fast forward a week and the majority of the time the water is cloudy/tan and will leave a light rust colored stain in the toilets that brushed away easily. The small cartridge filters that came with the house are stained rust colored. The second test showed elevated levels of iron and a mild rise in manganese, but everything else checked out okay. I had another test done to confirm what I was seeing and find out if it was ferric or ferrous iron.
The most reccent water test showed:
Iron .7 mg/L - They indicated that it was all ferric iron with no ferrous present. (No iron bacteria either)
Manganese .017 mg/L
PH 7.2
Hardness 4 GPG
At the same time they recommended a 1.5 cu/ft backwashing filter with Greensand Plus (clack setup).
My question is, why would they go with a greensand filter if I don't have any ferrous iron to remove? Shouldn't I be able to go with some type of carbon or other media backwashing filter followed by something like a 1 micron cartridge filter to clean up anything that sneaks past the media filter?
I'd really like to get something ordered soon to take the ferric iron out of the water but I'm not really sure what type of filter media to use. Thoughts?
