I would be very hesitant to use sand right from any of the local beaches, including Toms River. The local waters as we all know have been known to deposit lots of undesirable deposits on the beaches. Forget about the syringes from years ago, but there is still runoff from the local businesses and residences that wind up on the beaches, unseen, ie: fertilizers, sewage, various chemicals.
I just wouldn't chance it. Not worth the minimal savings IMO.
