When Kirby first brought one of the high-powered lights to the Gulf Coast beaches at night, he described seeing an entire beach “glow orange, literally, from the dune line to the water line.” He believed that the orange coloration under the UV light was a result of the oil mixing with Corexit, the chemical dispersant used to clean up the oil spill. It took almost two years of work, during which Surfrider sent 71 samples from the beaches for testing. The results verified that the material that glowed orange was, in fact, tar product from crude oil mixed with Corexit dispersant.
