National Ambient Air Quality Standards (NAAQS)
In this exercise, you will collect data on NAAQS exceedances for 2007. You will be collecting data for your home state and 5 others for 6 of the 7 criteria air pollutants. The data is accessed from the EPA Web site noted on our course homepage as EPA AirData. To access data, follow this procedure:
1) Click on the desired state
2) Click on the “Go!” icon (lower right-hand corner, next to map)
3) Using the “Monitoring” block of links (blue), select the “Monitor Values” link under the Reports header for the Criteria Air Pollutants
4) Select the desired pollutant from the drop down menu
5) Scroll farther down the page and set the “Lines per Page” option to 500
6) Select “Generate Report”
Complete the tables below.
