Wet 'n Wild has been slapped with a $42,000 fine.
The Orlando, Fla.-based attraction owned by NBCUniversal has been cited by the federal Occupational Safety and Health Administration for a near-drowning of one of its employees in August 2014, according to the Orlando Sentinel.
The investigation resulted in six serious citations, and a proposed penalty of $7,000 each.
"We take the safety of our team members seriously and always work to improve our safety programs," Universal spokesman Tom Schroder told the Sentinel in an email.
The incident occurred when an employee attempted to retrieve a patron's set of eyeglasses from the bottom of the Black Hole attraction and was held underwater by suction from one of the pumps.
In addition to failing to complete an entry permit for the employee to enter what OSHA considers a confined space, other violations include a lack of training and protocols.
The theme park has the option to appeal.
Past incidents involving improper training or inattentive lifeguards at various attractions throughout the U.S. have led to investigations after drownings.
