Columbus prepares for pool season, warns swimmers about waterborne illness

COLUMBUS (WCMH) — Last year, central Ohio encountered the largest outbreak of crypto in our state with more than 1,000 cases.

The outbreak forced some pools to close early for the summer.


Columbus city pools started cleaning and prepping its pools back in April, making sure they are chemically balanced and safe for swimmers.

“The main chemical is chlorine or hyper-chloride,” said City of Columbus Aquatic Administrator, John Gloyd.

Every Columbus city pool is equipped with electronic readers, checking and adjusting chlorine levels.

There is nothing to prevent crypto, once the water is infected there is a risk of the disease spreading.
