Run through a magnet and circulate with active carbon for a few days...........make sure you dont spot any oil on the water surface.

Did you take it a low tide or high tide? Sand at low tide is more "live" and has more beneficial bacteria.

i took it while its low tide, took some sand from the water n some sand up the shore, the sand looks very clean IMO,

but, remember punggol used to be a WW2 site rite ?, hahaha
