A well chlorination is an inexpensive procedure as a way to disinfect a home’s well system.  This preventative maintenance procedure should be done annually.  A well chlorination uses chlorine to shock your home’s well system as well as the copper piping inside the house.  This procedure helps to eliminate harmless bacteria causing a sulfur-like smell, alleviate iron buildup in the plumbing system, and keep iron bacteria under control.  It is important to have your well water tested for bacteria yearly by the local Health Department or an independent lab.

When to Chlorinate a Well?

• When the water in your home has a sulfur-like smell in the cold water only, caused by harmless bacteria in the water.
• As part of an annual regular maintenance in the spring, summer, or fall
• The well is producing iron bacteria found as a slime in the toilet tank
• When well work has been done on your existing well system.
• After flooding near the well cap and casing.
• Annual water test results indicate any presence of bacteria in the water
