Nonattainment Areas for Criteria Pollutants
The interactive map that I created shows county-level non-attainment status by pollutant and year. By clicking on a county, you can see in which years the county was out of attainment for a pollutant. It helps us visualize those areas that meet or violate air quality standards over time. This map was based on the EPA Green Book Data and the dataset that Nicholas Miller put together.
Please shoot me an email if you have any question related to this map.
