A plumbing problem forced an evacuation of Cobb County's White Water amusement park early Tuesday afternoon. "No guest was exposed to anything harmful," said Six Flags White Water spokeswoman Kendall Kelton. Likewise, the park's water supply wasn't compromised, she said. Plenty of guests were inconvenienced, however, but Kelton said that couldn't be helped due to the logistics of repairing the broken water line in one of the park's bath houses.
