There are a couple of ways to deal with iron in the water. For moderate iron a softener will often take care of the problem. A good filter will do it as well. For more iron and dissolved iron there are systems similar to softeners that will take the iron out. I had one on our shallow well back in Maryland. The one I had used Potassium Permanganate to rejuvenate the bed. Those systems work very well but they are something of a pain to maintain because of the potassium permanganate. The other method is to inject chlorine into the water which oxidizes the iron out of the water. I don't like chlorine personally so that system was a non starter for me right from the get go.
Call a water professional in your area and see what they recommend. My experience is over 15 years old and technology has moved forward since then.
