Report on Air Quality Trends in the District of Columbia
To better understand the current air quality status in the District, the following summary highlights key pollutants and their compliance with the National Ambient Air Quality Standards (NAAQS). These standards are designed to ensure the air remains safe and healthy for both residents and visitors. In this context, areas are classified as either in "attainment" (meeting EPA air quality standards) or "nonattainment" (not meeting them). The summary below outlines the District's current status with respect to these classifications. Ground-Level Ozone (O3): The District and the metropolitan region are currently in moderate nonattainment status of the 2015 8-hour ground-level O3 NAAQS, though have also been determined by EPA to have attained "clean data" and are in the process of submitting a redesignation request to EPA. Particulate Matter: The District is in attainment for the 2012 annual PM2.5 NAAQS and the 24-hour NAAQS. EPA strengthened the primary annual PM2.5 standard in 2024 from 12.0 μg/m³ to 9.0 μg/m³; this revised standard should be considered separately from the District's prior attainment status. Carbon Monoxide (CO): The District is in attainment for the current 8-hour and the 1-hour NAAQS.Sulfur Dioxide (SO2): The District is in attainment for the 2010 1-hour primary SO2 NAAQS and the 2024 annual secondary SO2 NAAQS. Nitrogen Dioxide (NO2): The District is in attainment for the 2010 1-hour and the 1971 annual NAAQS. Lead (Pb): The District is in attainment for the 2008 NAAQS.
