HAZMAT situation at Michigan's Adventure remains under investigation

MUSKEGON, Mich. (NEWSCHANNEL 3) - The cause of a HAZMAT situation at a West Michigan amusement park last week remains under investigation.

On Friday afternoon, nearly 30 people were sent to the hospital after a chlorine mishap at Michigan's Adventure in Muskegon County.

The pool was shut down and crews were called in.

Authorities believe two common chemicals were somehow combined in the pool, forming a dangerous chlorine cloud.

While human error remains a possibility for the mishap, the final determination by experts has not been made.
