You can imagine the crap they find in dredged sand coastally. Its been screened a couple of times before they can bag it, but small parts of pollution can get through like bacteria. Pieces of glass are probally the safest(most senseless pollution because we can control that) in sand anywhere unless you cut you foot! These days I would think you could find that and much more that could "slip through" the screening process, no matter where you get it from. I went through mine after I put it in the tank, didn't find anything but still had to look.
