The Hawaii Department of Health ordered the U.S. Navy to stop all operations at a Pearl Harbor facility in an emergency order Sunday after reports of petroleum contaminating the water supply.

The Navy received complaints last week from 680 households that the tap water at the Red Hill Bulk Fuel Storage Facility smelled and tasted like fuel. After the most recent testing, dangerous levels of petroleum were found in the water system at the joint Pearl Harbor-Hickam Naval and Army base.
