Aldergrove boil water advisory: what you need to know

Low levels of coliform bacteria at a water sampling point in one neighbourhood has caused the Fraser Heath Authority to issue a boil water advisory as  precaution for Aldergrove in the Township of Langley, B.C.

Officials say two consecutive clear tests results, 24 hours apart, are needed to to cancel the advisory and the earliest test results won't be available until July 8.

The advisory applies to the municipal water supply for Aldergrove. Affected areas include:

- east of 260 Street and west of 276 Street

- north of 24 Avenue and south of 36 Avenue

- spray park area only - Philip Jackman Park located at 32 Avenue and 271 Street is closed as a precautionary measure until the boil water advisory has been cancelled.

The township and the Fraser Health Authority are advising residents to boil their drinking water for at least one minute before drinking until further notice.

Water should also be brought to a rapid, rolling boil for at least a minute before using it to make baby formula, cook, brush teeth, wash raw food and make ice.

The presence of coliform bacteria can indicate contamination of the water with specific bacteria, viruses or parasites harmful to human health.

Drinking contaminated water can cause diarrhea, nausea and other stomach and intestinal illness, which can be fatal for babies, children, the elderly and those with a compromised immune system.

More health information about illnesses related to contaminated water can also be found at HealthLink BC

Small businesses coping

Small businesses were weathering the change over the weekend, but It's been a significant inconvenience. At Bob's Steakhouse in Aldergrove, it was business as usual as Angela McLaughlin went about serving patrons.

But McLaughlin says in order to open up the restaurant they had to bring in in cases of bottled water, bags of ice and bottles of soft drinks because the restaurant's soft drink gun is also attached to the water supply.

Some businesses decided to close altogether and residents had to take the time to go shopping for bottled water.
