Without standard clean sand, you can’t create the universal building material, concrete.
And with the scale of construction in any large city — any “concrete jungle” — the appetite for sand is immense.
New York City is no exception. While New York Sand & Stone (NYS&S) has the reputation as “the city quarry,”
the real source for its sand is Salem, N.J., a small port on Delaware Bay 30 hours away by boat.
The tugboat Daisy Mae and barge CMT Y NOT 2 move sand thousands of tons at a time.
One tug, one barge and a crew of five can transport the equivalent of hundreds of dump-truck loads.
