Which leaves many towns in southern Florida no choice but to dig their sand from inland quarries and haul it to the coast one roaring, diesel-spewing truck at a time. Tourists and locals hate the noise and traffic, and county officials hate the extra cost, which can be easily double that of dredged sand. But it does have some advantages. The inland mines, with their elaborate sorting and washing machines, can deliver sand of a precise spec—the exact size, shape, and color county officials deem appropriate for the beach. Beach town residents and tourists alike are very particular about the color and consistency of their beaches. The sugary white-sand beach has become the global standard of perfection, and any resort falling short of it loses points. (That’s nothing compared to the fussiness of Olympic beach volleyball players. To make sure their bare feet come into contact only with grains of just the right size and shape, sand was brought in from Hainan Island for the 2008 Beijing Games, and from a quarry in Belgium for the 2004 Athens Games.)15 “You pump sand from the ocean floor, you don’t know what you’re getting,” said Eastman. That’s not exactly true; sea sand is examined closely to make sure it is suitable for a given beach before the regulatory agencies will allow it to be dredged for nourishment. But land-mined sand can be sorted, sifted, and cleaned to a uniform standard. The grains that Eastman was emplacing were all about the size of a salt grain, all the same silver gray, unadulterated with stones or shell fragments. Their color was approved using the Munsell color order system, a visual index of hues created in 1915. The sand is tested at the mine, at every 3,000 tons, and every 500 yards on the beach after it’s in place to make sure it’s up to spec. The waves will gradually mix in shells and other organic matter, so in a few months it won’t look as obviously artificial as it does now.
