The BP Gulf of Mexico oil spill occurred in 2011, resulting from a deepwater drilling rig explosion that released millions of gallons of crude oil into the Gulf of Mexico. The incident had severe environmental and economic implications, including devastating effects on local ecosystems and communities. The Oil Pollution Act of 1990 was enacted to provide a framework for responding to oil spills, but it ultimately proved ineffective in containing the BP spill. It took BP over 80 days to stop the leak, which was largely due to the complexity of the situation and the company's lack of preparedness. Implementing a real-time monitoring system would have been most helpful to BP in preventing the spill, as demonstrated by the fact that similar systems had successfully detected leaks at other drilling sites.
