LOUISVILLE, KY (WAVE) - The swimming portion of Sunday's Ironman competition is officially a go. The recreational use advisory for the section of the Ohio River that encompasses the triathlon swim course was lifted.earlier on Friday by the Kentucky Division of Water (DOW) and the Kentucky Department for Public Health (DPH).
Recent sampling by DOW indicates the levels of microcystin toxin are now below the advisory threshold.
Harmful algae blooms detected in the water prompted the recreational advisory on September 18. The advisory was issued when water sampling results showed levels above the DOW recreational threshold of 20 parts per billion of mycrocystin toxins.
The recreational advisory remains in effect for the upper McAlpine pool to the West Virginia state line and from the McAlpine locks and dam to the Cannelton locks and dame in Hancock County.
