"I have a feeling that before Jaws came along there was some concern about sharks in the water from swimmers and surfers," the 64-year-old laughed.

- there was some concern about sharks in the water from swimmers and surfers
- there was some concern from swimmers and surfers about sharks in the water

Are both correct?
