Geosmin behind changes to Battlefords drinking water

Sep 4, 2026 | 2:39 PM

Residents in the Battlefords may notice an earthy or musty taste and odour in their drinking water as elevated levels of geosmin are detected in the North Saskatchewan River. 

Geosmin is a naturally occurring organic compound produced by certain algae and microorganisms. It can affect the taste and odour of drinking water at very low concentrations, although sensitivity varies from person to person. 

These occurrences are typically seasonal and are most common in the fall or following significant rainfall, when changing river conditions can increase geosmin production. 

Residents have taken to Facebook to share concerns about changes to their water. 

“Smells like lake water,” Kelsey Anne Craig said. 

“Finally someone said it, I thought I was the only one. But yes 100 percent! Its almost like a fishy smell,” Irvin Applegarth commented. 

“When I filled up my jugs earlier in the week the water seemed to be almost foamy in the jug and it’s never looked like that before,” said Jeremy Nicotine. 

City officials said they have received inquiries from residents about the water but stressed that geosmin does not pose a health risk. The City of North Battleford has adjusted operations at its water treatment facilities to help minimize the impact of geosmin on consumers.
