This morning a small team went to have a look.  As usual, there is a line  of litter on the high water mark. On the  mid-water mark, a dark layer.This dark layer on the mid-water mark is crude. On some parts, the crude is very obvious, forming a thick pudding-like mass on the surface.
In other parts of the shore, the crude has seeped into the midwater mark forming dark patches on the sand. There is  still a  sheen on the water surface everywhere, gathering in a thin brown scum  near the rocks as the tide receeds through the seawall.
A step on the black patches, and crude oil seeps up (the little black  sparkly bits that float up).
Litter on the shore retain the crude oil. There are still large sheets  of plastic on the midwater mark stained with oil. Fortunately, the  litter on the high shore doesn't seem to be heavily coated in crude oil. Despite the clean up effort at Tanah Merah two weeks ago, litter will keep washing up on this and our other shores.
Dark lines of crude are still found on the seawalls.
The crude that is still present on this shore results in a sheen of oil on the water surface, everywhere.
Well above the seawall, the big bags of crude-stained sand and other debris have been removed. But the oil has  seeped through the bags and into the ground where the bags used to be.
How is the marine life at Tanah Merah coping? I've done a separate post on the signs of life seen on this shore.
