Well Water Testing Reminder Services

The Middlesex-London Health Unit offers reminder services by e-mail or water sample bottles by mail to remind private well owners to test their well water for bacteria (total coliforms and E. coli). Learn more about each service and how to sign up below.

The Middlesex-London Health Unit suggests that private residences test their well water frequently, as water supply conditions can change allowing harmful bacteria into drinking water. Examples that could change water quality include: flooding or heavy rain fall/snow melt, well condition/maintenance, or nearby construction.

Who can sign up for these services?

If you live in Middlesex County or in the City of London and have a private well on your property you can sign up for these free services.
