The process begins by removing the cover over the well casing, adding the appropriate amount of chlorinating compound to three or four buckets of water and mixing thoroughly. For liquid chlorinating products with 5 percent to 6 percent available chlorinating chemical, use about 1.5 quarts of the chlorinating product. Place one end of the garden hose into the well as far as possible. Place the funnel into the other end of the hose and pour the contents of each bucketful of diluted chlorinating product through the hose while alternately raising and lowering the hose to disperse the disinfectant throughout the water supply. When the correct amount of disinfectant has been added, close the cover if the well has no pump. If it has a pump, draw the chlorinated water through all the fixtures and outlets until the smell of chlorine is noticed so that all of the piping and fixtures are disinfected. The chlorinating solution should remain in the entire water supply system for at least four hours and preferably overnight. Once the water source is chlorine-free, wait an additional two to five days and then sample for coliform bacteria. If coliform organisms are present, repeat the disinfection and sampling process.
