UPDATE: The boil water advisory has been lifted. The Capital Regional District says the Vancouver Island Health Authority tested the water and gave it an all clear on the afternoon of December 31.

About 80 homes on Salt Spring Island are under a boil water advisory until further notice.

The Capital Regional District (CRD) is testing the water to make sure it isn't contaminated, after a water main was damaged by a tree that had wrapped around it. The main was repaired Sunday.

Dan Robson, with the CRD, says the advisory is a cautionary measure.

"Because we really don't know if water quality was compromised, we'll go through the process of proving that out through water sampling and testing as well."

Robson says the CRD hopes to get the all-clear by Tuesday or Wednesday.

In the meantime, residents should boil water before drinking it, using it to prepare food, or brushing teeth. Full details and updates can be found on the CRD website.
