Many rural residents rely on private wells and cisterns as their drinking water source. In Hamilton, we estimate that there are about 10,000 private wells and cisterns in use.
The condition of water wells and safety of its water is the responsibility of the well owner. Unacceptable levels of bacteria, such as E.coli can contaminate a private water supply and put the health of those who use it at risk. Even a very small change in the well's structure, such as crack or a change in the environment such as heavy rain can result in significant changes to water quality. Public Health Services recommends private well and cistern owners do regular bacterial testing of their well and cistern water.

If you have an abandoned well that is no longer in use, check for funding to decommission your well. All abandoned wells raise health, safety and environmental concerns. Contaminated surface water, agricultural runoff and effluent from private sewage disposal systems can enter the groundwater through abandoned wells and cause pollution of other wells in the area used for drinking water.
