Maui Wildfire Data
Maui Wildfire Data
Since the wildfires in August 2023, DOH and other partners have been monitoring the environment around Lahaina and Kula to understand the impact of the fires and to help keep people safe. Monitoring helps us detect and measure potentially harmful substances in the environment, understand potential human health and environmental risks, make informed judgments and decisions, take actions to improve environmental quality and safety, and prevent pollution from the wildfires from entering the air, water, and the places people live, work, and play. This website provides public access to the data so people can make informed judgments about risks to their health, safety, and the environment.

This Conceptual Site Model shows how fire-related substances could move through the environment, how people are possibly exposed, and how sampling and monitoring programs have been set up to assess the potential for exposure and inform people about potential exposures. For more detail, see the information under the “What We Monitor” button above.
1. Air
Residents, visitors, and workers could breathe in particulates from the air. Measures are in place to stabilize ash and dust (Soiltac®) and suppress dust during removal activities. Multiple air monitors are continuously active and consistently show good quality air.
2. Settled Debris and Ash
Disturbed ash and debris could lead to skin contact and incidental ingestion. Safety measures protect workers during removal activities. Before allowing public access or issuing completion letters for rebuilding, samples are collected to confirm fire-related substance levels are below levels of public health concern.
3. Nearshore Water and Sediment
People could contact ash in water and sediment during recreation, especially after rain. Continued sampling shows that fire-related substance levels are below levels of public health concern, even on Brown Water Advisory days.
