Shellie Habel checks on a groundwater monitoring well at Centennial Park in Waikīkī on Feb. 14, 2025.

Shellie Habel is a hydrologist and geologist with the University of Hawaiʻi’s Climate Resilience Collaborative. Partnering with the Honolulu Board of Water Supply, Habel monitors groundwater wells in Waikīkī to study the hidden threat of rising sea levels.

HPR connected with her last week as she fished out specialized equipment from the Ala Wai Canal to study flood inundation. She said that her research over the years has tracked high levels of fecal bacteria correlating to high visitor counts in Waikīkī hotels, which makes you wonder how it’s getting in the canal.
