Residents in Metro Vancouver have been noticing an unusual smell in their tap water over the past few weeks. Social media platforms have been buzzing with complaints about the water tasting and smelling like mildew, mold, or mud. Some users likened the taste to algae or a fish tank. The Metro Vancouver Regional District has also received similar complaints.
According to Jeff Charrois, the program manager for quality control, around 60 calls were made to the district about the issue in recent weeks. This was an unprecedented situation for Metro Vancouver, with widespread reports of taste and odor issues. Further investigation revealed that the issue originated from the Seymour-Capilano Filtration Plant, which serves several areas in the region.
Testing identified an odorous compound called geosmin, a challenge faced by many drinking water utilities in Canada. Despite its unpleasant smell, geosmin poses no health risks, as it is naturally produced by cyanobacteria. Charrois assured residents that the water is safe to drink, as rigorous testing is conducted throughout the treatment process.
Geosmin’s presence at this time of the year is unusual for the region, typically occurring at the end of a hot summer or early fall. The duration of the issue remains uncertain, depending on natural factors. To address the taste concerns, Metro Vancouver has increased its use of water from the Capilano supply, which does not contain geosmin.
Charrois recommended storing water in the fridge to reduce the odor, as lower temperatures can help mitigate odorous compounds. Alternatively, adding a splash of lemon or cucumber can help mask the taste. Residents are advised to follow these tips until the situation improves.
