Well Chlorination

In the past, there was a method of well chlorination that consisted of pouring a gallon of household bleach down a into a well, then turning on the water in the house until the well flushed clean. There are even some Health Departments that still suggest this method. Well, guess what? occasionally it works and at times it does not.

One thing to keep in mind is that NO method of chlorination is 100 percent effective. The reason for this is that a well is not a stationary system. It is frequently affected by many underground factors that simply cannot be controlled.  A prolonged drought may dry up your water source. A extended period of rain can alter the path of your water source to abruptly bring surface water (which can hold bacteria) to your well or cause the water to change hardness, iron, pH, and more. A neighbor drilling a well could negatively affect the very underground water source that you rely on for your water source by affecting the quality and or the amount of water. Any one of these can seriously affect the performance of a well.

The first place to start in well chlorination is to find out the following information:

  1. How deep is the well?
  2. What is the static water level?
  3. What is the production rate of the well?
  4. Is there iron in the water?
  5. What is the pH of the water?

Once you know this information, you have made a big step towards getting started on your well chlorination.
