If the iron is high you will probably want to treat that--while not a health risk most people can't accept the aesthetics.
Any concern for PEX and PVC with respect to pin holes? I've got PEX inside and PVC from the well to tank to house. Virtually no copper,
except some of the PEX fittings (elbows, tees, etc) are copper or brass.
The high IRON is so far not apparent as far as stains, etc.
