Testing Private Well Water for Bacteria - Safe Water

Testing for Bacteria is Free

Public Health Services urges rural well and cistern owners to have their drinking water tested for bacteria on a regular basis. Test results for 2007 show that approximately 28% of water samples taken from private residential wells and cisterns in Hamilton have unsafe levels of bacteria. Public Health Services recommends that owners of these drinking systems test their water at least 3 times a year.

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 in your water quality.

Rural residents with private wells and cisterns are reminded to check the safety of their private well supply, know where their well is located, and to make sure that their water supply is constructed properly and protected from contamination sources.
