Iron Bacteria is one of the most simple forms of contamination that can be stopped. I can't believe that she (city) just stated that blanket fact without more of an explanation to all of you.

Iron Bacteria can be killed with a minimal about of chlorine. If the city is chlorinating their water by EPA standards, there shouldn't be Iron Bacteria present in the water system at all. How stupid are they??? If iron bacteria is present then other things are present!!!!!!

You would do better in addition to an attorney to notify the EPA. If the city isn't introducing enought treatment into the water, then they are putting the people at risk for anything!!!!

Iron Bacteria is not harmful in itself, pretty much a nusance. http://www.dnr.state.wi.us/org/water/dwg/febact.htm

Having Iron Bacteria present in a municipal water system however tells me that the city isn't treating their water up to standards and is putting residents at risk. This is not acceptable!
