Iron Bacteria

Removing iron can be complicated if iron bacteria are present. These organisms use iron as a source of energy, and they accumulate in jelly-like masses that can clog pumps, pipes and filtration systems. If a rusty slime builds up inside the toilet tank, iron bacteria are probably present. Though not harmful to health, these bacteria affect odor and taste. They may be difficult to remove. A shock chlorine treatment is recommended. The chlorine dosage is higher than the amount used for routine disinfection.

Correcting the Problem by Disinfection

Mix household bleach (Clorox, Dazzel, etc) with water in the well or spring in the following dosages:

DUG WELL

*Approximate amount of water in the bottom of a dug well and not the total depth of the well. For a surface SPRING, use 2 gallons.

DRILLED WELL

GAL = GALLON  QT = QUART

Once the chlorine has been mixed with the water, open all faucets, sillcocks and similar outlets until you smell chlorine in each outlet. Allow the mixture to stand in the system for 4 - 6 hours. Then flush the chlorine from the system using an outside faucet and garden hose. Do not flush the chlorine into your septic system. You may resume using your toilet facilities as the septic system is designed to handle this, but the septic system cannot handle the large amounts or water needed to flush the chlorine from the well. Since the chlorine will kill grass, be careful where you drain the water outside.

A repeat dosage may be necessary.
