Straw Bale Along the Coast to Slow the Oil
As some of you may know, straw bales are used as erosion control all the time during construction projects. They are used to form silt traps, like the one shown here. The concept is that the water is slowed down, but still flows through the bale. The straw which is netted in a web within the bale, traps the silt and doesn’t allow it to move through. I believe the same system could work for the oil that is floating along the surface of the water. If bales were set all along the coast line, they would act like silt traps or sponges and soak up the oil. If they didn’t actually soak up the oil, they would certainly slow down the water and cause the oil to accumulate at the face of the bales. This would make it thicker and easier to collect, as one of the big issues with this spill is the fact that the oil itself is thin and does not collect easily.
