With IRONMAN looming, latest tests show improvement to toxin levels in the Ohio River

Posted: Updated:

LOUISVILLE, Ky. (WDRB) - The Kentucky Division of Water says recent samples from the Ohio River show improvement to toxin levels that caused an advisory last month.

With several thousands IRONMAN athletes scheduled to race in Louisville on Sunday, officials say the sampling is encouraging.

The test results from around the course show microcystin toxin levels to be below four parts per billion. As long as tests show levels below 20 parts per billion, the races will likely go on.

That aforementioned advisory is still in effect, and a decision to lift if by the DOW will not be made until consecutive test below 20 parts per billion are obtained. 

Officials say more testing is planned for Tuesday.
