Things You'll Need

  • Garden hose

  • 1 gallon household bleach

  • Funnel (optional)


A slight bleach smell may reside from the water. Over a short period of time it too will disappear.

Contact your local health department regarding any special regulations for the testing of suspected drinking water supplies.


Some local agencies may require that only licensed personal conduct the sanitizing of the water wells.

A private well and the water it contains can become cloudy and contaminated from a number of reasons. Local flooding and pump replacement can cause the turbid water conditions. In both cases, the well water must be flushed and sanitized before it can provide clean, safe drinking water for the users. Sanitizing the water well is an easy process that will only take a full day and some effort on your part.


Step 1

Connect the garden hose to any outdoor spigot. Turn the water on. Run the well water from the hose until it becomes clear looking. Shut off the outdoor spigot.

Step 2

Pour the gallon of household bleach down the well casing. Some well casings will have either a fully removable top or a small breather hole to pour the bleach into the well. Use a funnel if the breather hole is too small to fill with bleach. Pay careful attention not to spill the bleach.

Step 3

Place the hose inside the well casing. Open the outdoor spigot with the garden hose still attached. Run the hose until a strong bleach odor is detected. Shut off the spigot.


Step 4

Open the cold-water faucets in your home one at a time. Run the water until the bleach smell is detected from each faucet. Shut off the faucets. Leave the heavy bleach water sitting in the plumbing pipes for five to 24 hours. The longer the better.

Step 5

Pull the garden hose from the well casing. Open the spigot valve and allow the bleach water to flush from the water system. Run the water from the hose until the heavy bleach smell has diminished. Shut off the spigot. Run the water from the household cold-water faucets. Allow the water to flush the indoor plumbing pipes until the bleach smell has diminished.
