*Occurred in Mexico waters, but oil traveled to US waters.
There may be incidents that NOAA was not involved in and therefore are not represented in this statistic. This list also focuses on spills on or into navigable waters. There have been large terrestrial and underground spills that are not listed here. Additionally, spill volumes may be inexact as some of these incidents involved fires, sinkings, hurricanes, and other conditions causing uncertainty.
