// Strategic Significance
The Honolulu Board of Water Supply serves 400,000 Oahu residents drawing primarily from groundwater aquifers. In November 2021 a fuel leak from the US Navy Red Hill Bulk Fuel Storage Facility contaminated the primary aquifer used by the Halawa water shaft which serves Joint Base Pearl Harbor-Hickam and nearby communities with JP-8 jet fuel. Thousands of military families reported fuel-tainted water causing illness. The Honolulu water system is on an island with no external water backup and is uniquely vulnerable to contamination events.
// Civilian Impact Assessment
Honolulu County with 1 million residents on an isolated island with no external water backup. The 2021 Red Hill fuel leak contaminated drinking water for thousands of military families. Island isolation means any major aquifer contamination has no alternative water source. Tsunami and hurricane risk threaten intake infrastructure.
