This report aims to identify where Bountiful fits among other metropolitan areas across the continental United States with respect to Hazardous Air Pollutants (HAPs)’ concentration and trends. To accomplish that, four other metropolitan areas with diverse levels of industrialization, population, geography, and climate were used for comparison. A crucial requirement in selection was for each area to have identical monitoring equipment and analytical methods.
