An unpleasant taste and odour have plagued the Morden water supply for the past couple months, though an end may be in sight.

Director of Public Works, Les Wieler, says they have been continuously observing and testing the water and while the unwanted taste and odour have lowered the quality, the water remains safe to drink.

The culprit of the issue was a large algae bloom in Lake Minnewasta.

Wieler says the hot and dry summer promoted the growth of the algae. The issue was further complicated because with water became stagnant without flowing over the dam regularly.

However, with the weather beginning to cool, Wieler says there's been a significant decline in algae growth.

"Colder weather and cloudy days help too. With less sunshine that dissipates the chances for algae growth. There’s a substantial reduction in the algae, we're thinking about 75 percent."

The last issue with algae was back in the 1980s. Wieler says they can't guarantee this issue won't happen again, so plans have been set in place for a future solution.

"Next year we're looking at a possible treatment. It hasn't been confirmed yet, but we are looking into avenues that we can treat the raw water specifically for algae."

If the weather continues to steadily drop, Wieler says the taste should return to normal in an estimated three weeks.
