Red Hill water crisis
The Red Hill water crisis is a public health crisis and environmental disaster caused by fuel leaking from the Red Hill Underground Fuel Storage Facility into the freshwater aquifer underneath the island of Oʻahu. Residents in military housing in and around Joint Base Pearl Harbor–Hickam began reporting chemical contamination in their tap water near the end of November 2021, and the Hawaiʻi Department of Health advised residents to stop using their tap water on November 29, 2021.
