Navy contractor Hannah Brumby packages a water sample at Hickam Main Child Development Center on Joint Base Pearl Harbor-Hickam, Hawaii, as part of the Navy’s Drinking Water Long-Term Monitoring program Feb. 28, 2024. The samples will be sent off-island to multiple Environmental Protection Agency-certified labs for extensive testing to determine whether total petroleum hydrocarbons (TPH) and over 60 other analytes may be present in drinking water. These ongoing monitoring efforts are part of the Navy’s enduring, long-term commitment to ensure the safety of the environment and public health.
