Naalehu-TS Air Monitoring Station, Naalehu, Hawaii | United States Environmental Monitoring

Naalehu-TS is an air monitoring station located at 95-5545 Mamalahoa Hwy in Naalehu, Hawaii. It is part of the Hawaii State Department of Health's ambient air quality monitoring network, which tracks criteria pollutants and other parameters to assess air quality across the islands. The station is operational and contributes to the state's compliance with the U.S. Clean Air Act. The station operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA) Air Quality System (AQS). As a monitoring site in a rural area of Hawaii, it likely measures pollutants such as particulate matter (PM2.5 and PM10), ozone, and other criteria pollutants. The network is designed to provide representative data for population exposure and background conditions. Environmental monitoring in Hawaii is critical due to the state's unique geography and volcanic activity. Naalehu-TS helps track air quality impacts from volcanic emissions (vog) and other local sources. The data supports public health advisories and regulatory decisions, ensuring that residents and visitors are informed about air quality conditions.

Naalehu is located on the southern tip of Hawaii Island, near active volcanic areas. Air monitoring in this region is essential for detecting volcanic smog (vog) and other pollutants. The station's siting provides representative data for rural and downwind areas, contributing to the state's understanding of air quality dynamics and supporting health-based interventions.
