Location: San Francisco Bay Material spilled: Bunker fuel Amount spilled: approx. 53,500 gallons Spill extent: 150 sq. miles; 26 miles of shoreline Heavy fuel oils are widely used to power marine vessels there have only been a few well-studied HFO spills. These fuels are different from other fuels (e.g., diesel and gasoline) in that they are made from the residue left behind after the distillation of crude oil distillation by adding cutting oils to decrease viscosity. Because both crude oils and cutting oils vary, there is no standard composition for HFOs and understanding how this variability in composition affects weathering is crucial to predicting impacts of future spills.

But that doesn’t mean it can also effectively identify lesser levels of oil that can have harmful impacts on ecosystems and public health. | ||||||||||||||||
