What happens if the bacteria return after chlorination?

If you have a return of total coliform bacteria, you can either have the well repaired or install a water treatment system such as a chlorinator or an ultra-violet light system. If fecal coliform bacteria returns, it is recommended to either repair the well or replace it. Disinfection treatment is not considered an acceptable remedy for wells with confirmed fecal coliform Bacteria.
