Fumes released at Holiday World theme park

The Chicago Tribune reports a filter malfunction at Holiday World, a holiday-inspired water park in Indiana this past Saturday. Numerous people suffered from breathing problems due to the fumes:

A filter pump malfunction in a water ride at southern Indiana’s Holiday World caused fumes that sent 42 people to a hospital with breathing troubles.
Park president Will Koch (COOK) says the pump sent highly concentrated levels of bleach and muriatic acid into the Bahari River waters at Splashin’ Safari on Saturday.

Life guards immediately got people out of the water and closed off the area. Some customers required first aid, others drove to the hospital or were taken there by ambulance. The issue has since been fixed and the ride re-opened.
