A: Spills usually happen due to bad weather (hurricanes, storms, and earthquakes), intentional acts of violence (like war, vandals, or dumping) and human mistakes. The main sources of the spilled oil are usually: 1. Tankers (boats that carry oil from one location to another) crashing, breaking, or running up on land. 2.
In the United States, the Coast Guard and the Environmental Protection Agency are two agencies that are responsible for cleaning up oil spills. When an oil spill occurs, the oil floats and forms a millimeter-thick layer on the surface of the water. Timing is crucial to prevent the slick's spread.There are four basic ways to clean or contain an oil spill, and workers determine the most appropriate method depending on the location of the spill, potential hazards, weather conditions, waves and currents. Contain the spill using booms, and collect the oil from the surface of the water using skimmers: Long, buoyant booms, which can be solid or inflatable tubes, surround and isolate the oil slick. 2  The booms rise about 3 feet (1 meter) above water level, and are attached to a skirt that hangs underwater.
