At this moment, there are no conclusive answers as inspectors zero in on the slide called the Emerald Plunge. They'll be considering things such as the drop, water flow and the height and weight requirements.
A brisk wind chilled the Memorial Day crowd up on the slide platforms at the dazzling new water park.
Four of the six slides are now open. One that had a flow meter problem on Sunday has been fixed and reopened.
The city of Dublin confirmed that Cal OSHA inspectors met with the manufacturer and contractors to figure out what happened on the Emerald Plunge on Saturday when a 10-year-old boy hydroplaned off the slide.

"So far, they are not drawing any conclusions. They really would like to speak with and have some questions for the manufacturer. Obviously, our collective goal is to get to the bottom of it," Dublin Asst. City Manager Linda Smith said.
Parents made their own risk assessments. "I thought I'll check out the slides first to see if I think it's OK and I'll let them know which ones to go on and which ones not to go on. I think they look OK but I told them to stay away from the open ones," Pleasanton resident Keelin Jardin said.

"I'm not much worried. These kinds of accidents happen. I'm sure people are taking care of that," Dublin resident Sonny Menon said.
The 10-year-old boy is recovering at home from the scrapes he got when he slid off the slide only 90 minutes after the park's grand opening.
The green slide and the one next to it will remain closed until the investigation is complete.
