Officials say they are super-chlorinating the pools.
“City officials were notified this evening by the Cerro Gordo County Department of Public Health of individuals who had symptoms prior to swimming at the Mason City Aquatic Center. We immediately closed all pools at the Aquatic Center and began the process to elevate chlorine levels,” said Brian Pauly, Recreation Superintendent for Mason City. “We will hold elevated chlorine levels to cleanse the pool of any bacteria before re-balancing pools back to safe levels of chlorine for our patrons.”
Pools are expected to reopen on Saturday, August 20th at 1:00pm.
Earlier, Brian Hanft of the Cerro Gordo public health department told the city that “due to confirmed cases of cryptosporidiosis of children that have been in the Mason City Family Aquatic Center in the past week we require that the pool be hyperchlorinated per CDC guidelines for a diarrhea’ incident.”
He sent a guidance document from the CDC on proper chlorination procedures.
