As of 2016, the wreckage of the USS Arizona still leaks oil into the Pacific Ocean. Even though it has been 75 years since the great ship sank, oil continues to be spotted above the water of the ship. After testing, it was determined to be safer to allow the wreckage to continue to leak than to remove the ship. Microbiologist Ralph Mitchell began some interesting work studying a certain bacteria that seemed to be feeding off the oil spilling out of the USS Arizona. His preliminary studies suggested that the bacteria was increasing how quickly the monument was corroding. His study and any course of action were halted due to budget concerns.
