Data

Red Hill Data Dashboard

The Data Dashboard is an interactive tool to help better understand the impacts of the November 2021 Red Hill fuel spill. The dashboard enables various spatial analyses through the addition of pertinent geospatial information.

Click on the different tabs at the bottom of the dashboard. The first tab, “Tap Water Screening,” shows screening results of potential fuel contamination in community tap water samples using fluorescence spectroscopy and displays the screening results with additional interactive features, including temporal trends. The second tab, “Impacted Schools”, can be used to understand the number of potentially impacted students and schools following the November 2021 fuel spill. The third tab, “Social Vulnerability Indicators”, helps visualize some of the most vulnerable populations in the area. Additional data will be added to the dashboard as it becomes available.

University of Hawaiʻi Tap Water Screening Dashboard

The Tap Water Screening Dashboard provides an interactive visualization tool to analyze spatial and temporal patterns of potential fuel contamination in tap water samples collected from December 2021 to the present. Tap water samples were collected from surrounding areas impacted by the Red Hill fuel spill. Sample collection is conducted through water screening requests.

The Joint Base Pearl Harbor-Hickam Groundwater Monitoring Dashboard contains up-to-date groundwater results from monitoring locations surrounding the Red Hill Bulk Fuel Facility dating back to 2016.

Additionally, the latest PFAS soil and groundwater sampling data are available here in response to the November 29, 2022 AFFF concentrate release.

Public Health Data

Infographic: Red Hill Registry data shows 87% reported new health symptoms, 93% switched water sources, 80% saw improvement after switching, and 37% sought medical care.

Results from surveys conducted by the State of Hawaiʻi Department of Health and the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry in February 2022 and September 2022 to learn about the experiences of people affected by petroleum contamination in the U.S. Navy’s Joint Base Pearl Harbor-Hickam drinking water system.
