About 40 people, mostly children, have fallen ill this afternoon due to a possible chemical exposure at an East Bay water park.
At 2:29 p.m., emergency crews responded to reports of a child complaining of respiratory problems after swimming at Antioch Water Park, located at 4701 Lone Tree Way, according to a fire inspector with Contra Costa Fire Protection.
The chemical exposure may be due to excessive chlorine that leaked into the pool, Fire Inspector Lisa Martinez said.
As of 4 p.m., 10 to 15 people had been taken to the hospital, Martinez said.
Parents have arrived at the park to pick up their children.
