KS Hawaii Air Monitoring Station, Keaau, Hawaii | United States

KS Hawaii is an air monitoring station located at 16-714 Volcano Road in Keaau, Hawaii, United States. Operated by the Hawaii State Department of Health, it is part of the national ambient air quality monitoring network that supports the US EPA's Air Quality System (AQS). The station contributes to the assessment of criteria pollutants and other atmospheric parameters in the Hawaii region. As a component of the EPA AQS network, KS Hawaii follows standardized methods for sampling and analysis, ensuring data comparability across stations. The station's last reported sample date is June 30, 2025, indicating ongoing operations. Typical monitoring at such stations includes ozone, particulate matter, and other pollutants regulated under the Clean Air Act. The station serves the community of Keaau and the broader Hawaii Island area, providing essential data for air quality management and public health advisories. Its location near Volcano Road may capture emissions from local traffic and volcanic activity, supporting studies on air quality impacts in volcanic environments.

The station's location on Hawaii Island places it in a unique environmental context influenced by volcanic emissions from Kilauea, which can release sulfur dioxide and particulate matter. Monitoring at KS Hawaii helps characterize background air quality and distinguish natural volcanic sources from anthropogenic emissions. The data supports compliance with National Ambient Air Quality Standards and informs public health alerts during volcanic events.
