The station is operated by the Navajo Nation Environmental Protection Agency (NNEPA), which reports data to the EPA AQS. Typical air monitoring stations in this network measure pollutants such as PM2.5, PM10, ozone, and nitrogen dioxide. The station's last sample date is February 24, 2025, indicating recent and ongoing data collection. Its location along Indian Route 27 provides representative sampling for the surrounding community and natural environment. This station plays a vital role in protecting public health and the environment in the Navajo Nation, a region with unique air quality challenges including emissions from power plants, mining, and residential wood burning. Data from Nazlini supports regulatory decisions, health advisories, and research on air quality trends in the Southwestern United States. The station's operation underscores the commitment to environmental monitoring in tribal lands.
Environmental context
The Nazlini air monitoring station operates in the Colorado Plateau region, characterized by high desert terrain and significant seasonal variations in temperature and precipitation. Local air quality can be affected by dust storms, wildfires, and emissions from nearby coal-fired power plants and mining operations. The station's siting is representative of rural background conditions, providing baseline data for assessing regional air quality trends and the impact of anthropogenic sources. Monitoring in this area is crucial for understanding pollutant transport and protecting the health of Navajo communities.
