Major oil spills like the 2010 Deepwater Horizon spill are devestating, but aren’t the only way oil gets into the ocean. Nearly 85 percent of oil in U.S. coastal waters comes from runoff (roads, parking lots, etc.), polluted rivers, airplanes, and small boats and jet skis. These sources add millions of gallons of oil to the ocean annually. Help stem the tide by maintaining your vehicle, fixing leaks quickly, and always recycling used motor oil.
