The USS Missouri and USS Arizona Memorial are shown in Pearl Harbor, Hawaii, on Monday, Dec. 7, 2020, on the anniversary of the 1941 Japanese attack. The Red Hill facility serves Pearl Harbor and holds 20 underground fuel storage tanks, which sit above an aquifer that supplies drinking water to Oahu. A 2014 leak from one of the World War II-era tanks caused concern the facility could contaminate drinking water. (Caleb Jones/AP)
