The 2023 Maui wildfires threatened the island’s drinking water, but fast action by the Maui Department of Water Supply helped avoid a major crisis. In past wildfires, harmful chemicals from melting pipes and smoke, specifically volatile organic compounds (VOCs), entered the water supply and spread to homes. In Maui, officials quickly shut off damaged areas, flushed the system, and worked with other agencies to test the water and share results with the public. At the same time, our team at the University of Hawaiʻi collected over 400 tap water samples from homes. We found very few VOCs during our sampling, showing that the county’s actions worked well. This study is the most detailed of its kind and offers a clear example for other communities on how to protect water after wildfires.
