(OP)
what is the best method to contaminate a commercial Silica sand with sodium chloride to a desired salt concentration?
I'm running an experiment in electrokinetic soil remediation using silica sandy soil..Silica sand is clean sand, how can I achieve a 500 ppm salt concentration in this commercial sand?

Sand weighs approximately 100 lbs/ cu ft. Add 0.05 lbs of salt to each cu. ft. of sand.

theoretically you may be right ! but how in practice ? should I add dry salt to dry sand and then moisture the sand or prepare a salt solution with the desired concentration and then add it to the sand??

please ask me more if things still unclear !

I would start with dry sand. Since sand has approximately 45% void space, determine the water volume.
557.27 cm3 * 45% = 250 cm3 of water to fill the void space. Dry sand weighs 1.6 kg per cm3. Water weighs 1 kg per cm3
Weight of sand = 557.27 *1.6 = 891 kg
Weight of water = 250 * 1 = 250 kg
Total weight = 891 + 250 = 1141 kg
NaCl required = 0.05% * 1141 = 0.57 kg
