While there are some filters that you can have installed onto your well to rid the water supply of rust, soil, or other particle debris, there are not really any filters currently that disinfect your water and rid it of bacteria that may be growing in it, such as E. coli. Cleaning the water yourself manually, though, is always an option by simply using unscented chlorine bleach.



Most people chlorinate their well water to disinfect it after some kind of repair has been done, after the well has not been utilized in a long time (like with a summer or winter home), to get rid of bacteria living in it, or to remove hydrogen sulfide buildup.

Before you start the process of cleaning your well water, you need to get enough water put back in jugs or buckets in your house to last the occupants of it for at least the next 24 hours. The water system in your home should not be used during this 24 hours period at all.

You need to use an unscented bleach for this job. This will have around 3 to 5 percent of sodium chlorite. You will need to use a different amount in your well depending on how deep and how wide your well is.

If the well is under 50 feet in depth and about 6 inches in diameter, you will need to use between 3 and 4 liters of bleach.

Your water supply should not smell like chlorine after the 24 hours is up. If it does, you will need to wait longer for the chlorine to be flushed from the system. You should not drink the water until it no longer smells like bleach.

If you notice a significant change for the better in the quality of your water supply after you finish this process, but the issue returns in the next couple of weeks or longer, the process will need to be repeated and you should probably add a bit more bleach to the water.

Repeat the process until the results last or seek help from a professional. It will be worth it in the long run when you do not have to worry about the safety of your home's water supply.
