When a well test indicates the presence of coliform bacteria, a Well Disinfection Service is the appropriate way to remove the bacteria from the well and supporting infrastructure. When bacteria are detected, the first line of disinfection is a non-invasive process using calcium hypochlorite. This FDA-approved powder is added to the well via the well head. After a period of five (5) days the water is re-tested to confirm the removal of the bacteria. During the five days the well can be used as normal.
Other conditions may necessitate well disinfection: anytime the well is opened for repairs; if flood water has entered a well; a new holding tank, pump or pressure tank has been installed; a new pipeline or other piping or plumbing work has been done; or odors or slime caused by iron or sulfur bacteria are present.
Coliform bacteria are often referred to as “indicator organisms”; while their presence is unlikely to cause an illness, they indicate the potential presence of disease-causing bacteria, such as E. coli, in water. In other words, their presence indicates that a contamination pathway exists between a source of bacteria (surface water, septic system, animal waste, etc.) and the water supply. Disease-causing bacteria may use this pathway to enter the water supply.
Allowing bacteria to grow in the well can be dangerous and lead to many health concerns. A first line of defense against bacteria is to disinfect the water system from the well through the entire infrastructure.
