The Okotoks Recreation Centre's Swindell's Leisure Pool has been closed until further notice.
According to a media release from the town, the pool is being closed in cooperation with AHS after an issue was found with the chlorine system.
The town describes a sample test of the pool's water from November 14 as "testing outside of normal parameters," with an HPC count over 100, but says AHS has told them there is minimal risk to people who have recently used the pool.
It will remain closed until further sample tests confirm the water is meeting safety standards.
Recreation Operations Manager Daniel Robinson was quoted.
"The health and safety of our community is our top priority, and as such, the decision to close the pool has been made in accordance with industry standards and guidelines... Routine water quality testing revealed higher than acceptable levels of heterotrophic plate count (HPC), necessitating immediate action to address and rectify the situation."
A new sample has already been sent for testing after the issue was corrected, and the town says the pool could reopen as early as Sunday, November 19.
The town will be reaching out to pool users whose schedule has been disrupted by the closure.
The Riley Minue pool, hot tub, and sauna are still open as usual.
