A boil order was issued Friday at Ravinia Festival in Highland Park for 24 hours, officials said.
Highland Park officials said the order was issued by the Lake County Health Department as a result of a water service repair.
“Drinking fountains and soda fountains within the Ravinia Festival grounds have been turned off,” officials said in an emailed statement.
Neighboring properties were not affected and can continue to use water, officials said.
No other information was immediately available.
