The City of Humboldt is closing in on a way to stop the smell from the lagoon that has annoyed residents for the past decade.

“Once we are fully comfortable to propose it as a solution, that’s when we’ll take it forward for approval for city council and potential implementation this year,” public works director Peter Bergquist told Bolt FM.

The smelly gas is created by bacteria in the first cell of the lagoon and goes by the name of hydrogen sulfide.

A Stantec Consulting study suggests adding ferric sulfate, which would break up the hydrogen sulfide and is already used in the last part of water treatment at the lagoon.

The idea is part of a broader study Stantec is conducting on how the city will provide water for an eventual population of 8,000 and beyond.
