If your water test indicates the presence of total coliform or E. coli bacteria and you so not see an obvious source of contamination, you should consider a chlorine shock for your well. The following chlorination process is usually effective in treating bacterial contamination in well water.


The following describes the equipment and steps you will need to follow to successfully disinfect your well. Shock chlorination is an essential procedure to help maintain a safe water supply system. This procedure should be used prior to start of operations at seasonal facilities, and annually at year-round facilities.

Equipment you will need includes:

  • A clean water hose to reach the closest outside faucet to well
  • A clean container (for storing if a hose is not available)
  • Standard household bleach (Use an unscented bleach)
  • A wrench to remove the well cap or well seal


  1. Bypass your water treatment equipment (if present). Follow the manufacturer's recommendation for cleaning water treatment equipment at this time.
  2. We recommend 1 cup of powered chlorine or 1 gallon liquid bleach to disinfect a well
  3. Remove the well cap. Be careful not to contaminate the cap. Pour the powder or liquid chlorine down the well casing, rinsing the walls thoroughly. If you have a hose nearby, flush hose water down the well until you can smell chlorine come out of the hose. This will mix the chlorine with the well water. If you do not have a hose nearby, then use 10 gallons of water and pour it slowly down the well, washing the casing wall. Recap your well.
  4. Run water through every tap in the house, including tubs, utility sinks, showers and toilets, etc. until you can smell chlorine. Let the chlorinated water sit in the lines for a minimum of 8 hours. Do not use chlorinated water for pets, house plants, bathing, or clothes washing.
  5. After 8 hours, discharge the chlorinated water onto a lawn or unused land area until you no longer smell chlorine. Do not empty into streams, ditches, or lakes, or into your septic system. The little remaining chlorinated water in house water lines can be emptied into your septic system or city sewer.
    (This process can take hours to complete. If you have a low yield well or are worried about running your well dry you can run the water for an hour and then wait for a couple of hours and run the water off again. Repeat this step until the smell of chlorine is no longer present.)
  6. Put your treatment equipment back in service. You can now use your water.
  7. A bacteriological analysis can be performed when chlorine is no longer present.
