CHID takes one water sample per week from rotating locations throughout the system. These samples are delivered by courier to an accredited lab for testing.  The lab sends the results to the Vancouver Island Health Authority.  Test results are maintained by Island Health, posted on its website, and are accessible for Public information.

In addition to the weekly water testing, CHID carries out quarterly well testing and annual full spectrum well testing.
