- 1). Open the top of the well casing. Pour the full contents of the bottle of bleach into the well.
- 2). Connect the garden hose to an outdoor water spigot. Place the other end of the hose down inside the well casing. Turn the outdoor spigot on. Wash down the inside of the well casing with the bleach water that is coming from the garden hose. Allow the water to run for up to one hour. Shut the outdoor hose spigot off.
- 3). Open all interior cold water faucets, one at a time. Run the water until a strong bleach smell is detected. Shut off the cold-water faucet. Allow the water system to sit, with the bleach water inside the plumbing pipes, for at least 24 hours.
- 4). Purge the water system of the chlorinated water. Open the garden hose spigot and allow the discharge water to run in an area that will not be damaged by the heavy concentration of chlorine water, i.e., an area free of plants and vegetation. The chlorine will soon evaporate from the discharged water. Close the outdoor spigot. Open the interior water faucets and run the water until the chlorine smell has diminished from these spigots as well.
- 5). Perform the same treatment again if the water begins to take on a rust-colored appearance. Test the water by taking a sample and sending it off to the local health department if the iron bacteria persists after a couple of treatments.
