The U.S. Environmental Protection Agency collects information on the presence of six pollutants (Carbon Monoxide, Nitrogen Dioxide, Ozone, Sulfur Dioxide, and “Particulate Matter”) in the air through dozens of measurement stations in Puerto Rico. It includes data for Puerto Rico, for several municipalities and for several statistical areas. This data is disclosed through four sections:
1) Air Quality Statistics Report: Provides statistics on the maximum value of the presence of each pollutant at all measurement stations located in the geographical area for one year.
2) Monitor Values Report: Provides statistics on the maximum value of the presence of each contaminant at each measurement station for one year.
3) Air Quality Index Report: Provides the Air Quality Index, which is an aggregated indicator of air quality that takes into account the presence of the six pollutants.
Specifically, the Air Quality Index is the maximum value obtained among all the pollutants, in a specific place. This section provides summary data for the Air Quality Index, such as the number of days in the year when the Index was so high that it is considered “very unhealthy” for a specific geographical area, and the maximum value obtained from the Index during the year.4) Air Quality Index Daily Values Report: Provides the daily value of the Air Quality Index and its components for a specific geographical area.
1) Inform the public about trends in water use in Puerto Rico and the United States.
2) To publicize how water supplies are affected by demographic, economic factors, public policy decisions and weather fluctuations.
